Peb lub tuam txhab muaj ntau hom me me caustic soda cog, yog tias koj cov zis qis, koj tuaj yeem xaiv cov nroj tsuag me me caustic soda, yog tias koj cov zis ntau, koj tuaj yeem xaiv cov nroj tsuag loj caustic soda raws li koj xav tau. Lub peev xwm ntau lawm ntawm cov khoom nce mus txog 2000~1,000,000 tons / xyoo, uas suav nrog yuav luag txhua qhov kev xav tau ntawm cov neeg siv khoom.
Abstract:Kev npaj ntawm caustic soda los ntawm ion-exchange membrane txoj kev yog ib qho ntawm cov kev npaj ntau hauv kev tsim cov dej qab zib caustic.
Ion membrane electrolysis soda ntau lawm yog cov txheej txheem siab tshaj plaws hauv kev tsim cov dej qab zib caustic hauv ntiaj teb: nws muaj qhov zoo ntawm kev siv hluav taws xob tsawg, tsis muaj kuab paug los ntawm peb cov khoom pov tseg, tus nqi qis thiab kev ua haujlwm yooj yim thiab kev tswj xyuas. Cov khoom los ntawm cov tshuaj chlorine thiab hydrogen tuaj yeem siv los ua ke hydrochloric acid, los yog ntxiv cov tshuaj chlorine downstream khoom xws li PVC, silicone thiab methane chloride. Caustic soda yog dav siv hauv papermaking, textiles, printing thiab dyeing, enamel, tshuaj, dyes, tshuaj tua kab, tanning, roj av refining, tsiaj thiab zaub roj ua, roj hmab, lub teeb kev lag luam thiab lwm yam sectors, raws li zoo raws li nyob rau hauv lub extraction ntawm alumina. thiab ua cov khoom siv hlau.
Lub hauv paus ntsiab lus:Ion-exchange membrane caustic soda yog tsim los ntawm electrolyzing dej ntsev los ntawm ion-exchange membrane txoj kev los ua caustic soda (xws li sodium hydroxide). Dhau los ntawm thiab tiv thaiv kev hla ntawm anions thiab gases, uas yog, tsuas yog tso cai rau H, thiab 2 ntxiv kom dhau, thaum Cl,, OH, thiab cov khoom bipolar H thiab C1 tsis tuaj yeem hla, yog li tiv thaiv cov khoom anode C12 thiab cathode 22 Cov khoom. H2 yog sib xyaw thiab tej zaum yuav ua rau muaj kev phom sij ntawm kev tawg kuj tseem ua lub luag haujlwm tiv thaiv C12 los ntawm kev cuam tshuam nrog lwm cov khoom cathode, NaOH, los tsim NaClO, uas cuam tshuam rau cov purity ntawm caustic soda.
Cov txheej txheem ntau lawm: Cov khoom siv tseem ceeb ntawm kev lag luam chlor-alkali: saturated brine, tab sis vim tias cov brine crude muaj sediment, C&2 ntxiv, Mg2 ntxiv, Fe3 ntxiv, S02- thiab lwm yam impurities, nws yog deb ntawm lub rooj sib tham. cov kev cai ntawm electrolysis, yog li nws yuav tsum tau purified thiab refined.
Hais txog Asia
Asia yog ib lub chaw tsim tshuaj paus ntawm Small Scale Caustic Soda Plant nplooj siab rau "zero emissions". Lub tuam txhab ua haujlwm ze nrog ntau lub tsev kawm qib siab hauv tsev thiab cov tsev lag luam muaj npe nrov. Lub tuam txhab siv "xoom tawm" ntawm cov dej khib nyiab ua haujlwm ua nws lub luag haujlwm.
Peb lub tuam txhab muaj ntau yam ntawm Caustic Soda Plant, uas npog yuav luag tag nrho cov kev xav tau ntawm cov neeg siv khoom.Yog tias koj cov khoom siv tsawg, koj tuaj yeem xaiv me me nplai caustic soda cog, yog tias koj muaj ntau lawm, koj tuaj yeem xaiv cov nplai loj caustic soda cog raws li rau koj cov kev xav tau.
Cov txheej txheem ntawm ion membrane txoj kev ua rau caustic soda:
1. Cov yam ntxwv ntawm ion-exchange membrane lye evaporation
(1) Cov txheej txheem yooj yim, cov cuab yeej siv tau yooj yim, thiab kev ua haujlwm yooj yim. Txij li thaum lub ionic membrane lye muaj tsuas yog ib tug me me npaum li cas ntawm ntsev, nyob rau hauv tag nrho cov txheej txheem ntawm evaporation thiab concentration, txawm tias nws tsim 99 feem pua ntawm cov khoom alkali, nws tsis yog yuav tsum tau tshem tawm cov ntsev. Qhov no ua kom yooj yim rau cov txheej txheem cov cuab yeej, uas yog, cov khoom tsim nyog desalination thiab txheej txheem engineering rau diaphragm alkali evaporation tau raug tshem tawm. Ntxiv mus, vim tsis muaj ntsev los nag thaum lub sij hawm evaporation txheej txheem, nws yog ib qho nyuaj rau ua rau pipeline blockage. Teeb meem dej, ua rau kev ua haujlwm yooj yim.
(2) Lub concentration yog siab, tus nqi ntawm cov evaporated dej yog me me, thiab cov chav noj yog tsawg. Cov concentration ntawm ion-membrane lye yog siab, feem ntau 30 feem pua, 33 feem pua, uas yog ntau dua li 10 feem pua, 11 feem pua ntawm cov membrane lye, yog li ntawd zoo heev txo cov chav siv rau concentration. Noj 32 feem pua lye ua piv txwv, yog tias qhov concentration ntawm cov khoom yog 50 feem pua, tus nqi ntawm cov dej distilled ib tuj ntawm 50 feem pua ua tiav caustic soda yog: 1 000732 feem pua, 1000750 feem pua, 1125 kg.
Yog hais tias txoj kev diaphragm electrolytic lye tseem yog concentrated rau 50 feem pua, cov dej ntim ntawm 6. ot feem ntau yuav distilled tawm. Qhov ntawd yog hais tias, concentrated rau tib 50 feem pua, txog 5.4t dej yog evaporated tsawg tshaj li lub diaphragm lye evaporation los ntawm ionic membrane lye evaporation. Vim qhov txo qis ntawm cov dej evaporated, cov chav noj tau txo qis heev. Siv cov txheej txheem ua ob zaug ua piv txwv, qhov kev siv lub zog yog feem ntau tsuas yog 0.73, 0.78t / t, thiab qhov chaw chav dej kuj txo qis raws li, yog li ntawd cov cuab yeej siv peev kuj raug txo raws li.
