Daim ntawv thov ntawm cov dej khov ua kom qhuav hauv kev kho dej khib nyiab ntawm cov nroj tsuag ntxuav roj ntuj yuav tsum tau soj ntsuam ua ke nrog daim duab theem ntawm Na2SO4-NaCl-H2O. Cov dej khov ua kom qhuav tsis yog tsuas yog cov txheej txheem ntawm kev sib cais ntsev thiab dej xwb, tab sis kuj tuaj yeem ua ke cov yam ntxwv solubility ntawm txhua cov ntsev inorganic los cais cov ntsev inorganic kom zoo los ntawm cov kauj ruam hauv cov txheej txheem evaporative crystallization. Txhawb nqa los ntawm theem sib npaug, cov thev naus laus zis tuaj yeem siv tsis yog hauv kev kho dej khib nyiab ntawm cov nroj tsuag ntxuav xwb, tab sis kuj tseem siv rau hauv cov dej hauv av roj, cov dej hauv av, dej ntsev pas dej thiab cov dej khib nyiab uas muaj ntau yam ntsev inorganic. Ntawm qhov kev sib cais dej ntsev, kev sib cais ntsev ntsev tuaj yeem ua tiav ntxiv. Cov ntsev inorganic sib cais tuaj yeem rov siv dua raws li qhov zoo ntawm kev sib cais, lossis siv ua cov khoom siv tshuaj lom neeg, lossis ua ntsev tsiaj txhu, uas tsis tuaj yeem tsuas yog ua tiav xoom qhov tso tawm ntawm cov dej khib nyiab kawg, tab sis kuj ua tiav kev rov ua dua tshiab ntawm ntau yam khoom muaj nqis.
Cov dej khib nyiab los ntawm lub tshuab lim dej ua ntej nkag mus rau hauv chav kho mob RO membrane. Tom qab ob theem membrane concentration, dej tshiab rov siv dua. Cov dej concentrated nkag mus rau hauv lub pas dej concentrated thiab nkag mus rau hauv lub tshuab evaporative crystallization system los ntawm lub twj tso kua mis. Hauv lub tshuab evaporative crystallization system, vim muaj qhov sib txawv ntawm Na2SO4 thiab NaCI solubility, nrog rau kev ua kom dej noo, cov kua khoom siv ntxiv concentrated, thiab Na2SO4 feem ntau crystallized thiab precipitated los ua nitrate slurry. Cov nitrate slurry nkag mus rau hauv lub tshuab centrifugal dehydration system los ntawm lub twj tso kua mis slurry. Tom qab kev sib cais cov khoom khov-kua, cov kua centrifugal niam rov qab mus rau lub tshuab evaporative crystallization system, thiab cov ntsev khov raug muag ua ntsev lag luam. Nrog rau kev ua kom qhuav, COD hauv cov dej nyoos tau nplua nuj nrog kev txo qis ntawm cov dej, uas ua rau cov kua pub nkag mus rau hauv lub tank evaporation nce ntxiv thiab cuam tshuam loj heev rau crystallization ntawm ntsev hauv cov txheej txheem evaporation.
Cov khoom siv pub rau cov evaporative crystallization skid yog brine los ntawm lub cuab yeej electrodialysis sab saud, thiab lub peev xwm ua tiav ntawm cov skid yog 300m3 / d. Lub sijhawm tsim khoom txhua xyoo yog 8000 teev.
Cov khoom siv tseem ceeb: Kev sib koom ua ke ntawm cov txheej txheem, compressor skid, sib xyaw hydrocarbon cia skid, twj paj nruag thiab tswj cov cuab yeej.
