磷酸鐵鋰行業壓濾機：選型、中試及應用投產全流程指南

磷酸鐵鋰（LFP）作為新能源動力電池核心正極材料，其生產過程（如磷酸鐵制備、鋰化反應、廢舊電池回收等）涉及大量固液分離環節，壓濾機作為關鍵分離設備，直接影響產品純度、生產效率、能耗水平及環保達標情況。本文結合磷酸鐵鋰行業工藝特性，詳細梳理壓濾機從選型、中試驗證到應用投產的全流程要點，結合行業實際項目案例與技術參數，為行業企業提供可落地的實操指南。

一、壓濾機選型：貼合工藝需求，兼顧效率與合規

磷酸鐵鋰生產中，壓濾機主要應用于亞鐵制備、水洗、母液處理、成品脫水及廢舊電池回收等工段，物料具有強腐蝕性（如酸性母液pH 1~2）、高粘度、細顆粒（粒徑多在1~3微米）、高附加值等特點，選型需突破“通用型”思維，圍繞工藝痛點、物料特性及環保要求精準匹配，核心遵循“適配性、高效性、經濟性、合規性”四大原則。

（一）選型核心前提：明確工藝需求與物料特性

選型前需全面梳理生產關鍵參數，避免設備“水土不服”，核心參數包括：

物料特性：磷酸鐵鋰生產中壓濾物料主要分為三類——亞鐵制備階段的反應漿料、鋰化后含雜質的混合液、母液處理后的污泥及廢舊電池回收中的浸出渣，需明確物料固含量（通常20%~40%）、粘度、顆粒粒徑、腐蝕性（如含硫酸根、鐵離子）及溫度（40~60℃）；其中酸性物料對設備材質要求極高，需重點關注耐腐性能。
工藝要求：明確壓濾核心目標——是濾餅脫水（如成品磷酸鐵鋰需低含水率）、雜質去除（如去除漿料中團聚顆粒）還是母液回收（如洗滌水套用）；成品工段需控制濾餅含水率≤5%（減少后續干燥能耗），母液處理工段需實現洗滌水高效套用，降低脫鹽水消耗（目標約15m3/噸產品）。
生產規模：結合產能確定壓濾機處理量，如年產5萬噸高壓實磷酸鐵項目，需配置10臺500㎡亞鐵制備壓濾機（帶壓榨功能）、5臺525㎡水洗壓濾機及2臺600㎡成品壓濾機；小型項目可選用單臺或多臺小型設備聯動，大型項目優先考慮自動化連續式設備。
環保與合規：需滿足《惡臭污染物排放標準》（GB14554-93）及當地廢水、固廢排放要求，如母液處理后產水電導率≤10μS/cm，雜鹽含水率≤50%，避免二次污染。

（二）核心選型參數：精準匹配設備性能

結合磷酸鐵鋰行業特性，壓濾機選型需重點關注以下核心參數，同時參考行業成熟項目配置經驗：

filtration area：根據物料處理量計算，公式為：過濾面積（㎡）= 物料處理量（m3/h）× 過濾時間（h）× 安全系數（1.2~1.5）/ 濾布有效過濾面積（m3/㎡·h）；磷酸鐵鋰行業常用過濾面積為400~600㎡，如成品工段多選用600㎡壓濾機，污水處理工段選用400㎡高壓污水壓濾機。
filtration pressure：物料粘度高、細顆粒多，需選用高壓機型，過濾壓力≥1.2MPa，隔膜壓榨壓力≥16bar（高壓隔膜擠壓可顯著降低濾餅含水率）；常規污泥脫水可選用1.2~1.6MPa，成品脫水需≥2.0MPa。
材質選擇：接觸物料的濾板、濾框、進料管需具備強耐腐蝕性，優先選用316L不銹鋼、增強聚丙烯（PP）或聚四氟乙烯（PTFE）材質；濾布選用耐酸、耐磨、孔徑適配的精密濾布（1~3微米），優先選擇PTFE/PA/PE材質，可實現自動排渣和反洗。
自動化程度：大規模生產（如年產5萬噸及以上）優先選用全自動立式隔膜壓濾機，具備PLC+觸摸屏智能控制，可實現過濾、擠壓、洗滌、風干、卸料、濾布清洗全流程自動化，減少人工干預；小型項目可選用半自動廂式壓濾機，平衡成本與效率。
輔助功能：需配套自動化學清洗裝置（含硫酸浸泡循環裝置），應對濾布堵塞問題；母液處理工段需配套精密過濾器（過濾精度5微米），實現二次過濾；部分工段需支持洗滌水四次套用，降低水資源消耗。

（三）機型對比與選型建議

磷酸鐵鋰行業常用壓濾機主要為廂式壓濾機與隔膜壓濾機，結合行業工藝需求，兩者對比及選型建議如下，同時參考行業項目實踐經驗：

機型	核心優勢	適用場景	行業應用案例	選型建議
Chamber Filter Press	成本低（比同處理量隔膜機型低30%-40%）、結構簡單、維護便捷，無隔膜易損件	母液預處理、低要求污泥脫水，濾餅含水率要求不高（25%-40%）的環節	貴州磷化開瑞6萬噸/年磷酸鐵項目母液預處理工段	小型項目、初期預算有限，或對濾餅含水率無嚴格要求的輔助工段
隔膜壓濾機（立式/臥式）	高壓壓榨（≤4.5MPa）、濾餅含水率低（≤5%）、洗滌效率高，可實現自動化連續運行，占地比臥式節省50%	亞鐵制備、成品脫水、水洗工段，廢舊電池回收浸出渣處理，對濾餅純度和含水率要求嚴苛的核心工段	銅陵安偉寧5萬噸/年高壓實磷酸鐵項目、陸良鴻泰博5萬噸磷酸鐵鋰項目核心工段	大型項目、核心生產工段，優先選用立式隔膜壓濾機，配套智能控制系統

補充說明：行業主流品牌優先選擇景津裝備、中大貝萊特、杭州興源環保等國內一線品牌，確保設備穩定性與售后保障，如貴州磷化開瑞項目明確要求壓濾機選用國內一線品牌。

二、中試驗證：銜接選型與投產，規避工業化風險

中試驗證是壓濾機從實驗室選型到工業化投產的關鍵過渡環節，核心目的是驗證選型設備的適配性、優化工藝參數、排查潛在問題，避免直接投產導致的效率低下、產品不達標、設備損壞等風險。磷酸鐵鋰行業壓濾機中試需結合行業工藝特點，遵循“模擬工業化、聚焦核心痛點、量化參數”的原則，具體流程與要點如下。

（一）中試前期準備

中試設備選型與搭建：選用與工業化擬采購設備同類型、同材質的小型試驗機型（過濾面積通常為1~5㎡），確保結構、原理、核心參數與工業化設備一致；搭建模擬工業化工藝的中試平臺，包括進料系統、壓濾系統、洗滌系統、卸料系統及檢測系統，參考鋰離子回收中試平臺的搭建邏輯，配備蠕動泵、洗滌水桶、檢測儀器等輔助設備。
物料準備：采集工業化生產中實際物料（如亞鐵制備漿料、鋰化后混合液、母液污泥），確保物料特性（固含量、粘度、顆粒粒徑、腐蝕性）與工業化生產一致；若物料獲取困難，可按工業化配方配制模擬物料，控制關鍵指標偏差≤5%。
檢測指標確定：明確中試核心檢測指標，重點包括：過濾速率、濾餅含水率、濾餅純度（如Li含量波動≤0.05%）、母液回收率、洗滌水耗量、設備運行穩定性（連續運行無故障時間）、濾布損耗情況，同時監測pH、TDS等水質指標。

（二）中試核心流程與操作要點

中試流程需模擬工業化生產的全環節，分階段開展試驗，逐步優化參數，具體步驟如下：

空載調試：先啟動壓濾機空載運行，檢查設備密封性能、液壓系統、自動化控制系統是否正常，重點排查濾板密封處是否滲漏、液壓壓力是否穩定、PLC控制系統是否能精準調控各環節（如擠壓壓力、洗滌時間），確保設備無機械故障。
單批次試驗：按工業化生產的進料量比例，向中試設備中投入物料，設定不同過濾壓力、壓榨時間、洗滌方式（單次洗滌/多次洗滌）、進料速度，開展單批次試驗；每批次試驗后，檢測濾餅含水率、純度、過濾速率等指標，記錄設備運行參數，參考隔膜壓濾機長程序（過濾→一次擠壓→洗滌→二次擠壓→風干→卸料）和短程序（過濾→擠壓→風干→卸料）的操作邏輯，對比不同程序的運行效率。
多批次連續試驗：選取單批次試驗中效果最優的參數組合，開展連續24~72小時多批次試驗，模擬工業化連續生產場景；重點監測設備連續運行穩定性、濾布堵塞情況、洗滌水套用效果，記錄每批次的能耗（電、水），排查設備易損件（濾布、密封件）的損耗規律，同時驗證洗滌水四次套用的可行性，監測脫鹽水消耗是否達到行業標準（約15m3/噸產品）。
異常工況模擬：模擬工業化生產中可能出現的異常情況，如物料固含量波動、物料溫度過高/過低、進料壓力不穩定等，觀察設備應對能力，優化應急處理方案；例如，模擬酸性物料pH值異常波動（1~3），檢測設備材質的耐腐蝕穩定性，避免工業化生產中出現設備腐蝕泄漏問題。

（三）中試數據整理與優化建議

中試結束后，需對試驗數據進行系統整理、分析，形成中試報告，為工業化投產提供數據支撐，核心要點包括：

參數優化：根據試驗數據，確定最優工藝參數，如過濾壓力、壓榨時間、進料速度、洗滌次數及洗滌水用量，明確濾餅含水率≤5%、母液回收率≥90%的參數區間，同時優化洗滌水套用流程，降低水資源消耗。
設備適配性驗證：判斷所選壓濾機機型、材質、輔助功能是否滿足工業化生產需求；若出現濾餅含水率不達標、設備腐蝕、濾布堵塞頻繁等問題，需調整選型方案（如更換材質、增加輔助清洗裝置），例如，若濾餅純度不達標，可更換更精密的濾布（1~3微米）。
風險排查與應對：梳理中試過程中出現的問題（如設備滲漏、濾布損耗過快、自動化控制系統故障），制定工業化投產中的應對措施，如定期清洗濾布、更換密封件、優化PLC控制程序，同時明確易損件的更換周期和儲備量。
成本測算：根據中試數據，測算工業化生產中壓濾環節的單位成本（包括設備折舊、能耗、濾布損耗、人工成本），對比不同設備方案的經濟性，優化選型決策；例如，隔膜壓濾機雖前期投入高，但濾餅含水率低可減少后續干燥能耗40%，長期綜合成本更具優勢。

中試報告需明確結論：所選壓濾機是否可滿足工業化生產需求，最優工藝參數是什么，存在哪些潛在問題及應對措施，為后續設備采購、車間布局、工藝制定提供核心依據；參考廢舊磷酸鐵鋰電池回收中試的報告規范，確保數據真實、參數量化、建議可落地。

三、應用投產：標準化落地，保障穩定高效運行

壓濾機中試驗證合格后，進入工業化應用投產階段，核心是實現設備標準化安裝、工藝參數落地、人員規范操作，同時建立完善的運維體系，確保壓濾機長期穩定運行，適配磷酸鐵鋰工業化生產的連續性、高效性需求。結合陸良鴻泰博、銅陵安偉寧等項目的投產經驗，具體流程與要點如下。

（一）投產前期準備

設備采購與驗收：根據中試報告確定的設備型號、參數、品牌，采購工業化壓濾機及配套設備（如進料泵、洗滌泵、濾布、化學清洗裝置、精密過濾器）；設備到貨后，對照采購合同、技術協議，驗收設備外觀、材質、參數、配件完整性，重點檢查濾板材質、濾布精度、自動化控制系統是否符合要求，如316L不銹鋼濾板的材質檢測、PLC系統的功能調試。
車間布局與安裝：結合生產工藝流程、設備尺寸、操作空間，合理規劃壓濾機安裝位置，確保設備進料、卸料、洗滌、排水順暢，同時預留檢修空間（設備周圍≥1.5m）；安裝過程中，嚴格遵循設備安裝規范，確保濾板安裝平整、密封良好，液壓系統、管道連接無滲漏，電氣系統接地可靠；參考貴州磷化開瑞項目的車間布局要求，將壓濾系統與預處理系統、干燥系統、尾氣處理系統合理銜接，占地面積控制在規定范圍內（如95m×64m界區）。
人員培訓：對操作、檢修、運維人員進行系統培訓，內容包括設備工作原理、操作流程、參數調節、安全注意事項、常見故障處理、濾布更換與維護等；培訓后進行考核，確保操作人員能熟練操作設備，檢修人員能快速排查處理常見故障，重點培訓自動化控制系統的操作的和酸性物料處理的安全規范。
工藝銜接調試：將壓濾機與前后工序（如反應釜、干燥機、母液回收系統）進行銜接調試，確保進料量、進料速度與前后工序匹配，避免出現物料堆積或供應不足的情況；調試過程中，逐步導入中試確定的最優工藝參數，模擬工業化生產的連續運行模式，重點調試洗滌水套用流程與母液回收系統的銜接，確保產水水質達標（電導率≤10μS/cm）。

（二）試生產階段：逐步磨合，優化參數

試生產是投產的關鍵過渡，需分階段開展，逐步提升生產負荷，排查問題、優化參數，確保設備與工藝適配：

低負荷試生產（30%~50%負荷）：啟動壓濾機及配套系統，以低負荷運行，重點監測設備運行穩定性、物料處理效果、工藝銜接情況，記錄濾餅含水率、純度、過濾速率、能耗等數據；排查設備密封、管道連接、自動化控制系統的潛在問題，及時調整參數，如優化進料速度、調整壓榨壓力，確保設備無滲漏、無故障。
中負荷試生產（50%~80%負荷）：逐步提升生產負荷，模擬正常生產工況，重點優化工藝參數，確保濾餅質量（純度≥99%、含水率≤5%）、母液回收率（≥90%）達標，同時監測洗滌水耗量、能耗水平，優化洗滌流程，實現洗滌水高效套用，降低脫鹽水消耗；觀察濾布損耗情況，確定濾布更換周期。
滿負荷試生產（100%負荷）：以工業化滿負荷運行，連續運行72小時以上，全面驗證設備的穩定性、工藝的合理性、人員的操作熟練度；重點排查設備長期運行后的易損件損耗、液壓系統穩定性、電氣系統可靠性，同時監測環保指標（廢水、固廢排放）是否達標，如雜鹽含水率≤50%、氨氣排放符合GB14554-93標準；針對出現的問題，及時優化調整，形成標準化操作流程（SOP）。

（三）正式投產：標準化運維，保障長期穩定

試生產合格后，進入正式投產階段，核心是建立標準化的操作、運維、檢修體系，確保壓濾機長期高效運行，降低生產成本，具體要點如下：

標準化操作：嚴格執行SOP，操作人員按規定的參數（過濾壓力、壓榨時間、進料速度、洗滌次數）操作設備，禁止擅自調整參數；做好設備運行記錄，包括進料量、濾餅產量、含水率、能耗、設備運行狀態等，實現生產過程可追溯；重點規范酸性物料處理的操作流程，避免物料泄漏導致設備腐蝕或人員安全問題。
日常運維與保養：建立日常運維臺賬，定期對壓濾機進行檢查、清潔、保養，重點包括：① 濾布：定期清洗、檢查，若出現破損、堵塞，及時更換（一般更換周期為1~3個月，根據物料腐蝕性調整）；② 液壓系統：定期檢查液壓油液位、純度，及時補充、更換液壓油，排查液壓管路滲漏；③ 密封件：定期檢查濾板密封件，若出現老化、破損，及時更換，避免物料滲漏；④ 電氣系統：定期檢查PLC控制系統、傳感器、線路，確保運行正常；⑤ 輔助設備：定期清洗化學清洗裝置、精密過濾器，確保輔助系統穩定運行。
故障排查與處理：建立快速故障排查機制，針對常見故障（如濾餅含水率過高、設備滲漏、濾布堵塞、自動化系統故障），制定標準化處理流程，確保故障發生后能快速處理，減少停機時間；例如，濾餅含水率過高，可調整壓榨壓力、延長壓榨時間或更換濾布；設備滲漏，可檢查密封件或濾板安裝情況，及時維修更換。
成本控制與優化：定期分析壓濾環節的生產成本（能耗、濾布損耗、人工、維修），優化工藝參數，降低成本；例如，通過優化洗滌流程，減少洗滌水用量，實現洗滌水四次套用；合理安排設備檢修，減少設備故障停機時間，提高設備利用率；批量采購濾布、密封件等易損件，降低采購成本。
環保合規管控：定期監測壓濾環節的廢水、固廢排放情況，確保符合環保標準；母液處理后的產水需回收利用，污泥需按規定處置，避免二次污染；定期檢查尾氣處理系統，確保氨氣等有害氣體達標排放，符合《惡臭污染物排放標準》。

（四）投產后期優化升級

正式投產后，結合生產實際情況，持續優化壓濾機運行參數、運維體系，同時關注行業技術升級，適時進行設備改造或升級，提升生產效率、降低成本；例如，引入智能監測系統，實時監測濾餅含水率、濾布狀態，實現精準運維；結合“靶向提鋰技術”等行業新技術，優化母液回收流程，提升鋰回收率（目標≥94%）；針對生產規模擴大，適時增加壓濾機數量或升級設備規格，適配產能提升需求，如陸良鴻泰博項目二期投產后，可根據產能增加情況優化壓濾機配置。

四、行業應用注意事項與常見問題解決方案

（一）核心注意事項

材質適配是關鍵：磷酸鐵鋰生產中物料多為酸性，需嚴格選用耐腐材質（316L不銹鋼、PTFE等），避免設備腐蝕導致物料污染、設備損壞，尤其是濾板、濾布、管道等直接接觸物料的部件。
濾布選擇需精準：濾布孔徑需與物料顆粒粒徑匹配（1~3微米），同時具備耐酸、耐磨特性，避免濾布堵塞或破損導致濾餅純度不達標、過濾效率下降；定期更換濾布，避免因濾布老化影響生產。
參數控制需穩定：過濾壓力、壓榨時間、進料速度等參數需嚴格按中試確定的標準執行，避免參數波動導致濾餅含水率過高、母液回收率下降，影響后續干燥、燒結工序的產品質量。
安全與環保并重：操作過程中需做好安全防護（如佩戴防腐蝕手套、防護眼鏡），避免酸性物料接觸皮膚；嚴格落實環保要求，做好廢水、固廢、尾氣的處理，確保合規生產。

（二）常見問題及解決方案

五、總結

磷酸鐵鋰行業壓濾機的選型、中試、應用投產是一個系統性工程，需緊密結合行業工藝特性、物料特點及生產需求，實現“選型精準、中試充分、投產規范”。選型階段需聚焦物料腐蝕性、濾餅含水率、生產規模等核心需求，優先選用適配的隔膜壓濾機，搭配耐腐材質與精密濾布；中試階段需模擬工業化場景，優化工藝參數，排查潛在風險，為投產提供可靠數據支撐；投產階段需注重標準化操作、常態化運維，保障設備穩定高效運行，同時兼顧成本控制與環保合規。

隨著磷酸鐵鋰行業的規模化發展與技術升級，壓濾機正朝著自動化、智能化、高效化、節能化方向發展，企業需結合自身產能與工藝需求，持續優化壓濾環節的設備配置與工藝參數，降低生產成本、提升產品質量，同時參考行業成熟項目經驗，推動壓濾機在磷酸鐵鋰生產及廢舊電池回收中的高效應用，助力行業綠色可持續發展。

1 Introduction

Zinc sulfide ores are the main source of zmc metal in the world, in which zinc generally exists in forms of sphalerite and marmatite. Currently,more than 80 per cent of the zinc is produced by conventional zinc hydrometallurgical methods, including roasting, leaching and electrowinning processes [1, 2]. % of the zinc is produced by conventional zinc hydrometallurgical methods, including roasting, leaching and electrowinning processes [1, 2]. During the roasting process, ZnS is converted to ZnO, but a significant fraction of ZnO reacts with the iron impurities to form zinc ferrite [3-51]. Zinc ferrite is insoluble in mild acidic conditions, strong Hs. A considerable amount of leaching residue will be produced in the subsequent leaching process [f6, 7]. In addition, the leaching reaction rate decreases over time due to the decreasing acid concentration during the tradifional leaching process in the stirred tank. Consequently, incomplete leaching will OCCur, thereby further increasing the generation of zinc leaching residue (ZLR), leading to a significant waste of resources and a high environmental impact. Consequently, incomplete leaching will OCCur, thereby further increasing the generation of zinc leaching residue (ZLR), leading to a significant waste of resources and a high environmental risk [8, 9]. The high demand for zinc has attracted the interest of industry to utilise the ZLR as a valuable secondary source [1].Hydrometallurgical processes are dely applied to recycle zinc from ZLR due to their significant advantages of lower capital and operating costs, as well as being less harmful to the environment [1, 1]. environment [1, 2]. Currently, the most common hydrometallurgical process is to recover zinc from ZLR in a bath of hot concentrated sulfuric acid [10]. high extraction rate of zinc can be obtained using this process, but incomplete leaching still occurs due to the leaching in the stirred tank.Moreover, the hot concentrated acid leaching process involves a high extraction rate of zinc in a bath of hot concentrated sulfuric acid. Moreover, the hot concentrated acid leaching process involves a long reaction time f4-6¨and consumes an enormous amount of energy and sulfuric acid More importantly, in most electrolytic zinc plants, the ZLRs containing water-soluble zinc with a content of less than 5 per cent of the ZLRs were used to produce the ZLRs in the stirred tank. More importantly,in most electrolytic zinc plants, the ZLRs containing water-soluble zinc with a content of less than 5% are directly discharged or heaped, causing a portion of the zinc losses. The water-soluble zinc can cause soil contamination, water pollution and several other serious environmental pollution through the leachate by rainfall [8, 9]. Therefore, finding a cost effective and environment friendly process to recover zinc from ZLR remains a major challenge. The membrane filter press (MFP), which is a common machine on solid． The membrane filter press (MFP), which is a common machine on solid-liquid separation, has advantages of low cost, high solid content and outstanding efficiency that has been widely used in various industries. years, the washing functionof MFP has also been attracting attention for use in the titanium dioxide, sugar,pigment and electrolytic manganese metal In recent years, the washing functionof MFP has also been attracting attention for use in the titanium dioxide, sugar, pigment and electrolytic manganese metal industries[1b14]. LIU et al[14] recovered 50%of water-soluble manganese from an electrolytic manganese residue fEMR) via a MFP using water. -based water washing technology could be industrially applied because it solves the problem of ''water swelling". swelling", which commonly occurs in previous water washing technologies [1 4, 1 5]. On the basis of the previous work of LIU et al [1 4], we attempted to wash the EMR via a MFP using anolyte. In 2009, the MFP-based technology on the leaching and recovery of manganese from EMR via a combination of anolyte washing with water was developed. combination of anolyte washing with water washing was realized and resulted in a patent application being submitted (No. CN1 024700A) 『1 61.Note that However, the possibility of using this technology in the hydrometallurgical zinc production process has not yet been demonstrated. However, the possibility of using this technology in the hydrometallurgical zinc process has never been investigated previously. The thickening, pulping, second leaching, washing, filtering and pressing would be integrated and realised using a single MFR In addition, the leaching of zinc from ZLR In addition, the leaching of zinc from ZLR in the form of spent electrolyte washing would be performed under constant acid concentration via a continuous flow of spent electrolyte. Hencethe feasibility of leaching and recovery of zinc from ZLR would be improved. feasibility of leaching and recovery of zinc from lcaching residue of zinc calcine based on MFP was investigated, combining spent electrolyte washing with flesh water washing. For this work, the uniformity of filter cakes, which is directly related to the leaching result, was examined. Based on this experimental result, the 1eaching and washing on extracting zinc from ZLR were subsequently studied.

1 Introduction

The ZnS04-contained slurry was pumped into MFP through central feeding hole and filter pressed to obtain the filter cakes (i.e., ZLR); next, the filtrate (1eaching liquor) entered the subsequent production process. 3. 1eaching in Ⅳ[FP: Spent electrolyte at the desired temperature was pumped into the MFP and reacted with filter cakes to leach zinc again and simultaneously recover part of ZnS04. 4) water washing: The filter cakes were washed again with flesh water to further recover ZnS04. 5) pressing: Water with a pressure of 1.5 mL was used for the treatment. with a pressureThe eluate obtained from spent electrolyte washing and flesh water washing steps was then pumped into the membrane plates, which was maintained for 20 min to reduce the water content of filter cakes, and the pressed filter cakes were subsequently discharged from the MFP and transported to landfills. The eluate obtained from spent electrolyte washing and flesh water washing steps were collected and returned to spent electrolyte tank and eluate collection tank. The eluate obtained from spent electrolyte washing and flesh water washing steps were collected and returned to spent electrolyte tank and eluate collection tank, respectively.

3 Results and discussion

3.1 Filter cake formation To obtain a high zinc ex仃action rate and recovery rate using an MFP.the most important step is to obtain uniform filter cakes.the particle size of zinc calcine and sedimentation time.which are directly involved with the width of the filter chambers. particle size of zinc calcine and sedimentation time, which are directly involved with the width of the filter chambers, are the most important parameters regarding the uniformity of filter cake. The particle size of zinc calcine and sedimentation time, which are directly involved with the width of the filter chambers, are the most important parameters regarding the uniformity of filter cake. The five-spot test (upper left, bottom left, centre,upper right, bottom right) was used for estimating the uniformity of the filter cakes by measuring the zinc content. The five-spot test (upper left bottom left, centre, upper right, bottom right) was used for estimating the uniformity of the filter cakes by measuring the zinc content and thickness of the cakes at these selected points. Through observation of the filter cakes formed in the MFP, it is found that triangle cakes were easily formed using raw zinc calcine. The presence of zinc calcine of large particle size inhibits the formation of uniform cakes due to its good The presence zinc calcine of large particle size inhibits the formation of uniform cakes due to its good settleability: thus, small size particles should be selected.Choosing the particle size of zinc calcine less than 106 gm仃,able 1 1. which could be obtained in actual production, a series of experiments regarding the filter cake formation were conducted. and the results are presented in Fig．2. From Fig.2.2, using zinc calcines with particle sizes less than 1 06 gm, the zinc content and filter cake thickness vary clearly at the five tested points when the When the filter chamber width is 40 mln, suggesting that the cake uniformity is poor under this condition, which might be due to long sedimentation time. When the filter chamber width is 30 lnnl, the cake uniformity is improved significantly relative to the chamber width of 40 nun. When the filter chamber width is 20 mm, the cake uniformity is improved significantly. When the filter chamber width is 20 mm, the cake uniformity is similar to the results obtained as the chamber width is 30 mm. Thus. it can be clearly observed that the uniforlTl filter cakes could be formed by choosing the particle size of zinc calcine to be less than 1 06 Bm for filter chamber widths of 20 mm and 30 mill. As a result, the zinc calcines with particle size 1ess than 1 06 Bm were used in the following filter chamber.

3.2 Leaching of zinc from zinc calcine In this lcaching process, 1 00 L of spent electrolyte solution was added to a 300 L stainless steel drum equipped with a variable speed stirrer and then stirred for approximately 1 h at a speed of 60 r/min. Next, the 1eaching solution was adjusted by adding zinc calcine or Next, the 1eaching solution was adjusted by adding zinc calcine or sulfate acid until the final Zn "concentration of electrolyte was in the range of 130-140 g／L and the final H2S04 concentration was in the range of l-2 g／L. Subsequently, the ZnS04-contained slurry was filtered using a MFE The analysis results of zinc calcine and ZLR are presented in 1 'ables 2 and 3. The analysis results of zinc calcine and ZLR are presented in 1, 2 and 3, respectively. As presented in Table 2, the grade of zinc calcine is 57.52%, in which ZnO approximately accounts for 90.06% of total zinc in mass. Table 3 indicates that in this process of leaching, most of the Zn0 is converted to ZnS04, resulting in the dramatic decrease of the content of ZnO. Table 3 indicates that in this process of leaching most of the Zn0 is converted to ZnS04, resulting in the dramatic decrease of the content of ZnO. After solid-liquid separation using the MFP, many insoluble materials are concentrated in the residue. leaching residue is higher than 20%, causing the extraction rate of zinc in this process to be less than 90%. Analysis of ZLR indicates that zinc iS mainly presented in the forills of ZnO. presented in the forills of ZnFe204, ZnO and ZnS04, which in total account for uD to 80% of the zinc iS.(Thus, a secondary leaching process is required to recover the remaining zinc.

3.3 Leaching of zinc from ZLR In this leaching process, the zinc was extracted from ZLR obtained in Section 3.2 in the form of spent electrolyte washing To dissolve ZnFe204 using MFE, strict leaching conditions, such as high temperature (above 90°C, and high concentration of acid solution (100 -200 g/L), were applied. -Under hi. temperature and high acid concentration conditions, the extraction rate of zinc can increase to approximately 97% [19, 20]. approximately 97% [19, 20]. To enable a comparison with the extraction rate obtained in the traditional route, the lcaching conditions in the present work are under a temperature in the range of 0.5 to 0.5°C. The extraction rate of zinc was determined as follows The lcaching conditions in the present work are under a temperature in the range of 90 to 96 oC and an acid concentration in the range of 1 00 to 200 g/L. Becanse alsoe leaching residues of zinc calcine Becanse also e leaching residues of zinc calcine were fixed in the chamber of the MFP. the high reaction temperature condition was realized through heating of the spent electrolyte. Figure 3 shows the Zn "and H2S04 concentrations with the MFP. Figure 3 shows the Zn "and H2S04 concentrations with leaching time under atemperature in the range of 90 to 96 oC during the leaching process based on MFE From Fig. 3, the Zn "concentration is the highest in the chamber. The Zn "concentration is observed to obviously increase during the initial 5 min, followed by a decrease to 55 gui after washing for 60 min and only a slight change around the level of 55 g/L in the following 30 min. Conversely'the H2S04 concentration obviously decreases during the initial 5 min. followed by a decrease to 55 g/L in the following 30 min. Conversely'the H2S04 concentration obviously decreases during the initial 5 min. followed by an increase to 11 7 g／L after washing for 60 min and then slight changes around the level of 120 g／L in next 30 min. Based on these Based on these above results, it can be concluded that the violently reaction of the leaching residue with the hot spent electrolyte only lasts for approximately 60 min. The analysis result of the residue after hot concentrated acid leaching for 90 min is presented in T2lble 4. Clearlv. the zinc content in the residue reduces significantly from over 20% (Table 3) to less than 1 0% (Table 41. As a consequence, the zinc extraction rate 1ncreases to 97%. This result obviously demonstrates that using a MFP as a leaching reactor could not only ensure a high extraction rate but also reduce the leaching time compared with the traditional hot concentrated acid The short leaching time using a MFP might be due to the constant reaction conditions of high temperature and high acid concentration during the whole process when using a MFE Based on the above results. The short leaching time using a MFP might be due to the constant reaction conditions of high temperature and high acid concentration during the whole process when using a MFE Based on the above results． temperatures, such as at 30 oC, 60 to 70 oC, 70 to 80 oC and 80 to 90 oC. to reduce the energy consumption further. The zinc extraction rate at 30 oC is 92.67% and increases to 94.95% at 60 to 70 oC. When the 1eaching temperature is further increased to 80 to 90 oC, the ex仃action ratio increases to 94.95% at 60 to 70 oC. The ex仃action ratio increases to 95.56%. The temperature of spent electrolyte has an obvious effect on t11e zinc extraction ratio. high zinc extraction could be obtained by increasing the temperature of the electrolyte. High zinc extraction could be obtained by increasing the temperature of leaching, which is consistent wim the results of Ref．f191. Under Iow temperatures, the energy consumption is lower,the extraction ratio can be increased by 1.5 per cent. Under Iow temperatures, the energy consumption is lower,the extraction ratio can not reach the traditional result of 97%.In conelusion, the hot acid leaching only at 90 to 96 oC or above can achieve the ideal result(i). achieve the ideal result(i.e., more than 97%,...).

3.4 Recovery of water-soluble zinc

The water-soluble zinc approximately accounts for 3%of the total zinc in the residue after hot acidTo recover this part of the zinc, the leaching residue was further washed with Water. Figure 5 shows that both the Zn2+and H,S04 concentrations of eluate decrease with increasing washing time. Figure 5 shows that both the Zn2+and H,S04 concentrations of eluate decrease with increasing washing time.especially in the initial 5 min. These results indicate that Zn "and H,S04 These results indicate that Zn "and H,S04 in the zinc residue could be quickly washed out by Water using the MFP. After washing for 25 min, the final Znz+and H2S04 concentrations of eluate decrease to 0.05 ki and H2S04 concentrations of eluate. to 0.05 g/l and 1.25 g/l.pectively. The final residue obtained after being washed and pressed merely contains 6% of zinc. in which the water-soluble zinc only accounts for 0.07% (Table 5), suggesting that the majority of water-soluble zinc is recovered during the water washing process. Compared with the traditional hot concentrated acid leaching process, the water-soluble zinc lost in the leaching residue iS very 10 %. The water-soluble zinc lost in the leaching residue iS very 10W. 3.5 Washing uniformity To estimate the washing results, the washing uniformity of MFP was examined by measuring.Both the total zinc and the water-soluble zinc were measured. Both the total zinc and the water-soluble zinc contents in the final residue. As presented in Rlble 6. change slightly at five selected points (upper left, bottom left, centre,upper right, and bottom right) in the residue, indicating that the hot spent The zinc that can be extracted in zinc calcine and the Water-soluble zinc that can be recovered in the residue are completely uniforiil. The zinc that can be extracted in zinc calcine and the Water-soluble zinc that can be recovered in the residue are completely extracted and recovered by USing the MFP.

4 Conclusions

1] The use of a MFP is found to be completely feasible and effective to 1each and recover zinc from leaching residues ofzinc calcine.

2] The zinc calcines with particle size of less than 1 06 gm and MFP chambers with a width of 30 I/IlTI are proper for establishing unifornl filter cakes to obtain acceptable leaching and recovery results.

What is the filter press in the plant for?

cairui2003 — Wed, 26 Jun 2024 00:15:53 +0000

Filter press is a kind of mechanical equipment widely used in industrial production, especially in the fields of sewage treatment, chemical industry, metallurgy and environmental protection. In the factory, filter press is mainly used for solid-liquid separation, i.e., separating the solids in the liquid and solid mixture from the liquid. In this article, we will introduce the use and working principle of filter press in the plant in detail, so that readers can better understand this equipment.

I. Use of filter presses

Filter presses are mainly used in the following areas:

1. Wastewater treatment: In the field of wastewater treatment, filter presses are mainly used for sludge dewatering. The sludge after treatment in the bioreactor and sedimentation tank is piped to the filter press for dewatering. The filter press dewater the sludge by applying pressure so that the water in the sludge is squeezed out. The dewatered sludge cake can be further treated or utilised.

2. Chemical: In the chemical field, filter presses are mainly used for solid-liquid separation. For example, in the production of sulfuric acid, chemical fertiliser and other chemical products, it is necessary to separate the solids in the raw materials from the liquid, and at this time, the filter press can be used for separation.

3. Metallurgy: In the metallurgical field, filter presses are mainly used for solid-liquid separation of mineral slurries. The filter press can separate the useful minerals in the slurry from the solids, such as waste rock, and improve the utilisation of the minerals.

4. Environmental protection: In addition to the above fields, filter presses are also widely used in the field of environmental protection. For example, in the treatment of industrial wastewater, municipal sewage, etc., filter presses can be used for solid-liquid separation, so that the treated water quality meets the emission standards.

Second, the working principle of the filter press

The filter press is mainly composed of feed pump, filter mesh, pressing mechanism and hydraulic system. Its working principle is as follows:

1. The feed pump conveys a mixture of liquids and solids into the filter screen of the filter press.

2. The function of the strainer is to retain the solids on its surface while the liquid flows out through the strainer. At this point, the solids are compressed on the surface of the strainer to form a cake.

3. The pressing mechanism presses the plate frames on both sides of the filter chamber to generate a certain pressure. As time passes, the pressure gradually increases so that the water in the filter cake is squeezed out.

4. The hydraulic system is the power source of the filter press, which pushes the movement of the piston rod and plate frame through hydraulic oil to achieve the functions of filtration and compression.

5. When the preset filtering time or pressure is reached, the filter press automatically unloads and loosens the plate frames on both sides of the filtering screen chamber. Subsequently, the filter cake on the filter screen is scraped down and discharged by the scraper, completing the whole filtration process.

III. Advantages of filter presses

1. High separation efficiency: the filter press adopts high-pressure filtration technology, which can complete the separation of a large number of solid-liquid mixtures in a short time.

2. Energy saving and environmental protection: Compared with traditional separation methods such as sedimentation tanks and centrifuges, filter presses consume less energy during operation and produce less sludge, which is conducive to environmental protection.

3. High degree of automation: most of the modern filter presses adopt intelligent control system, which can realise the functions of automatic feeding, automatic control of pressure and time, etc., which reduces the manual operation and improves the production efficiency.

4. Wide range of applications: due to its features of high efficiency, energy saving and environmental protection, the filter press has a wide range of application prospects in various fields.

As an efficient and energy-saving solid-liquid separation equipment, the filter press is widely used in factories. Its working principle is mainly to make the solids in the liquid and solid mixture be retained on the filter mesh by applying pressure and form the filter cake, while the liquid flows out through the filter mesh. After a period of time, the pressure mechanism is loosened, and the scraper scrapes down and discharges the filter cake, completing the whole filtration process. In the fields of sewage treatment, chemical industry, metallurgy, environmental protection and so on, the filter press plays an important role. With the continuous progress of technology and the increase of application demand, the performance and function of the filter press will be further improved and perfected in the future.
