Kev xaiv cov txheej txheem ntau: Caustic soda nroj tsuag ntawm qhov ntsuas no feem ntau xaiv cov txheej txheem tsim nyog raws li lawv tus kheej cov txiaj ntsig zoo, cov khoom siv raw, thiab cov nqi txiav txim siab, xws li ion exchange membrane txoj kev. Cov txheej txheem ion txauv membrane yog siv dav hauv cov khoom loj loj caustic soda vim nws qhov zoo ntawm purity siab ntawm caustic soda tsim, siv zog siv tau zoo, thiab kev sib cais zoo ntawm cov khoom lag luam xws li chlorine thiab hydrogen. Los ntawm kev xaiv permeability muaj nuj nqi ntawm ion txauv daim nyias nyias, kev tsiv teb tsaws ntawm ions raug tswj tau meej, kom cov tshuaj sodium chloride raug hloov mus rau hauv cov dej qab zib caustic, chlorine thiab hydrogen hauv electrolyzer, nteg lub hauv paus zoo rau cov khoom tom qab refining thiab los ntawm - kev siv cov khoom.
Cov yam ntxwv ntawm cov txheej txheem thiab qhov zoo: Piv nrog rau cov txheej txheem diaphragm ib txwm muaj, cov khoom lag luam caustic soda tsim los ntawm ion exchange membrane txoj kev muaj cov impurities tsis tshua muaj xws li sodium chloride, uas feem ntau tuaj yeem tswj tau nyob rau hauv ib qho me me. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau daim ntawv thov scenarios uas yuav tsum tau high-purity caustic soda, xws li ib co zoo tshuaj synthesis tshwm sim thiab hluav taws xob-qib khoom tsim. Tsis tas li ntawd, tag nrho cov txheej txheem ntau lawm kuj ua tau zoo hauv kev tswj kev siv hluav taws xob. Los ntawm rationally configuring electrolytic hlwb, optimizing fais fab mov, thiab txais kev txhawb siab txheej txheem xws li evaporation thiab concentration, nws muaj peev xwm txo tau lub zog noj ib chav tsev cov khoom thaum ua kom tiav cov zis, yog li txhim kho lub Hoobkas kev lag luam cov txiaj ntsig thiab kev sib tw hauv kev ua lag luam.
Cov khoom siv tseem ceeb:
Electrolyzer: Cov khoom siv tseem ceeb hauv kev tsim cov dej qab zib caustic. Ob lub diaphragm thiab ion txauv membrane electrolyzers ncaj qha cuam tshuam cov zis, zoo, kev nyab xeeb, thiab ruaj khov.
Evaporator: Cov tshuaj caustic soda los ntawm cov electrolyzer feem ntau tsis tshua muaj siab, yog li cov evaporator siv los ua kom nws cov concentration. Multi-effect evaporators, uas siv cov chav rau cua sov thiab evaporate dej, feem ntau yog siv rau lub zog-npaum concentration, tsa lub caustic soda rau cov qauv kev lag luam (xws li, 30%, 32%, lossis 50%).
Kev sib cais thiab kev huv: Cov khoom siv lim tshem tawm cov khoom impurities, thaum ion txauv resin yees tshem tawm cov kab hlau ions (piv txwv li, calcium, magnesium) thiab lwm yam impurities, kom ntseeg tau siab-purity, ruaj khov-zoo caustic soda rau kev siv.

Cov khoom siv raw khoom thiab kev tswj xyuas zoo
Qhov chaw ntawm cov khoom siv raw: Cov khoom siv tseem ceeb ntawm sodium chloride feem ntau yog xaiv cov ntsev uas muaj txiaj ntsig zoo, uas tuaj yeem los ntawm hiav txwv ntsev, ntsev zoo lossis ntsev ntxhia. Lub Hoobkas yuav tsim kom muaj cov khoom siv raw khoom ruaj khov channel. Rau cov ntsev hiav txwv, cov dej hiav txwv zoo thiab cov txheej txheem ziab tshav ntuj ntawm cov ntsev yuav raug tshuaj xyuas kom ntseeg tau tias cov ntsiab lus tsis huv ntawm cov ntsev yog nyob rau hauv ntau yam tswj tau; rau cov ntsev zoo thiab ntxhia ntsev, yuav tsum tau them nyiaj rau kev ruaj ntseg zoo thaum lub sij hawm mining txheej txheem thiab ua ntej ua ntej kev sib txuas los xyuas kom meej tias cov ntsev nyoos nkag mus rau hauv lub Hoobkas ua tau raws li qhov yuav tsum tau ua.
Kev Tswjhwm Zoo: Ua ntej cov khoom siv raw nkag mus rau cov txheej txheem tsim khoom, yuav muaj cov txheej txheem ua ntej nruj, suav nrog kev sib cais, nag lossis daus, lim, thiab ntxiv cov tshuaj ua kom zoo rau cov tshuaj tiv thaiv thiab tshem tawm impurity. Los ntawm kev tswj xyuas cov kev mob tshwm sim, xws li kub, pH, thiab tus nqi ntawm cov tshuaj refining ntxiv, cov impurities hauv cov ntsev nyoos raug tshem tawm mus rau qhov siab tshaj plaws, xyuas kom meej tias cov brine nkag mus rau hauv lub cell electrolytic yog siab purity, muab ib qho yooj yim. lav rau kev ruaj khov ntawm cov khoom lag luam zoo caustic soda, thiab zam cov khoom puas lossis cov khoom tsis zoo vim yog cov khoom tsis huv.
