  • 氨堿廢渣壓濾處理查定及完善

    601

    工藝查定目的 由于城市環(huán)保的要求,氨堿廢渣的排放已成為困擾企業(yè)的一大難題。原有的用液體廢渣船運(yùn)輸已不能適應(yīng)環(huán)保的要求,必須將廢渣的液體輸送改為固體運(yùn)輸。為了掌握板框壓濾機(jī)的準(zhǔn)確生產(chǎn)能力,了解影響其生...

  • 壓濾機(jī)在堿渣廢液分離中應(yīng)用

    703

    引言 堿渣廢液是氨堿法生產(chǎn)純堿工藝中蒸餾母液回收氨后剩余的固液混合物,其主要成分為CaCO。、CaO、CaCl2、NaCl、Mg(OH):等,據(jù)統(tǒng)計(jì),每生產(chǎn)1t純堿排出的堿渣廢液約9~10m3。隨著環(huán)保壓力的加大,且對(duì)堿渣廢液...

  • Utilisation of plate and frame filter presses in the soda ash industry

    556

    Reasons for utilising plate and frame filter presses In the soda ash production process, brine refining is required to improve product quality, reduce ammonia, salt, and carbon dioxide losses in the production process, and reduce scarring in the tower piping. Raw salt is dissolved in hot water to make saturated crude brine. In the process of removing magnesium and calcium, a slight excess of stone is added...
