Cov khoom siv tseem ceeb:
Xws li cov kua qaub thiab ntsev tso tso tsheb hlau luam, cov khoom siv kho cov kua khib nyiab, thiab cov cuab yeej pabcuam.
Cov kua qaub ntsev tov cia tank suav nrog cov kua dej khib nyiab (pas dej), cov kua qaub tshiab, cov kua qaub tshiab, oxidant, catalyst thiab lwm lub tank cia. Nws cov hom muaj xws li ntsug, kab rov tav, hauv av, thiab lwm yam. Nws lub peev xwm yog txiav txim siab los ntawm kev tsim kev suav, thiab cov khoom yuav tsum yog acid resistant thiab ntsev tov corrosion-resistant. Lub tank cia qhov chaw yuav tsum tau tiv thaiv corrosion, qhov cua, thiab kev ntsuas thaum muaj xwm ceev yuav tsum tau txiav txim siab.
Cov khoom siv kho cov kua khib nyiab thiab cov cuab yeej pabcuam sib txawv nyob ntawm txoj kev kho:
(1) Cov cuab yeej siv rau lub tshuab nqus tsev vacuum crystallization txoj kev suav nrog lub tshuab nqus tsev crystallization, nrog rau plaub lub evaporator. Nws muaj 1 evaporator, 3 crystallizers, 6 chav injectors, 1 lub ntsiab condenser, thiab 1 ob chav condenser. Thiab nruab nrog cov cuab yeej pabcuam xws li ferrous sulfate centrifugal separator, acid twj, thiab lub tshuab nqus tsev twj.
(2) Lub evaporation concentration freezing crystallization txoj kev yog nruab nrog graphite evaporator thiab separator, lub tshuab nqus tsev twj tso kua mis, crystallization tank (nrog stirring thiab khov dej ntsev coil hauv), ammonia tub yees chav tsev, lub tshuab nqus tsev lim los yog centrifuge, thiab lwm yam.
(3) Cov txheej txheem polymeric ferric sulfate yog nruab nrog lub twj tso kua mis, cov kua dej pov tseg, nruab nrab cia tank, metering tank, catalyst dissolution tank, roj-dawb cua compressor, cua cia tank, oxygen cylinder, oxygen buffer tank, polymerization reactor, khoom hloov twj tso kua mis, thiab tail gas absorption tower.
