Kev piav qhia

Daim ntawv thov ntawm evaporative crystallization skid nyob rau hauv cov dej khib nyiab kho cov roj purification cog yuav tsum tau soj ntsuam nyob rau hauv ua ke nrog nrog rau theem ntawm daim duab ntawm Na2SO4-NaCl-H2O. evaporative crystallization tsis yog tsuas yog cov txheej txheem ntawm kev sib cais ntsev thiab dej, tab sis kuj tuaj yeem ua ke cov yam ntxwv solubility ntawm txhua inorganic ntsev kom cais cov ntsev inorganic zoo los ntawm cov kauj ruam hauv evaporative crystallization system. Kev txhawb los ntawm theem sib npaug, thev naus laus zis tuaj yeem siv tsis tau tsuas yog hauv kev kho dej khib nyiab ntawm cov nroj tsuag kom huv, tab sis kuj hauv cov dej hauv av, hauv av brine, dej ntsev hauv pas dej thiab cov dej khib nyiab uas muaj ntau yam inorganic ntsev. Ntawm qhov chaw ntawm kev sib cais dej ntsev, kev sib cais ntsev ntsev tuaj yeem ua tiav ntxiv. Cov ntsev uas tsis muaj dej sib cais tuaj yeem rov qab siv tau raws li qhov zoo ntawm kev sib cais, lossis siv los ua cov khoom siv tshuaj lom neeg, Los yog ua tsiaj txhu ntsev, uas tsis tuaj yeem paub tsuas yog xoom tso tawm ntawm cov dej khib nyiab, tab sis kuj paub txog kev rov ua dua tshiab ntawm ntau yam khoom muaj txiaj ntsig.

Cov dej khib nyiab los ntawm cov nroj tsuag purification ua ntej nkag mus rau RO membrane kho chav tsev. Tom qab ob-theem membrane concentration, dej tshiab yog rov qab siv dua. Cov dej concentrated nkag mus rau hauv lub pas dej ua ke thiab nkag mus rau evaporative crystallization system los ntawm lub twj tso kua mis pub. Nyob rau hauv lub evaporative crystallization system, vim qhov sib txawv solubility ntawm Na2SO4 thiab NaCI, nrog rau cov evaporation ntawm dej, cov ntaub ntawv cov kua yog ntxiv concentrated, thiab Na2SO4 yog precipitated crystallized thiab precipitated rau nitrate slurry. Cov nitrate slurry nkag mus rau hauv lub centrifugal lub cev qhuav dej los ntawm slurry twj tso kua mis. Tom qab cov kua dej sib cais, cov centrifugal niam cawv rov qab mus rau lub evaporative crystallization system, thiab cov khoom ntsev yog muag raws li kev lag luam ntsev. Nrog rau cov evaporation, COD nyob rau hauv cov dej nyoos yog enriched nrog qhov txo ntawm cov ntsiab lus ntawm cov dej, uas ua rau kom nce viscosity ntawm cov kua pub nyob rau hauv lub evaporation tank thiab cuam tshuam rau crystallization ntawm ntsev nyob rau hauv cov txheej txheem evaporation.

Cov khoom noj khoom haus ntawm cov evaporative crystallization skid yog brine los ntawm cov khoom siv hluav taws xob sab saud, thiab cov peev txheej ua tiav yog 300m3 / d. Lub sijhawm tsim khoom txhua xyoo yog 8000 teev.
Cov cuab yeej tseem ceeb: Cov txheej txheem kev sib koom ua ke skid, compressor skid, sib xyaw hydrocarbon cia skid, ntsuas thiab tswj cov cuab yeej.
