Chlor Alkali Ntau Lawm Cog

 

 

Cov tub ntxhais ntawm chlor - Alkali cog (siv cov txheej txheem sib txuas ua piv txwv) yog los tsim cov tshuaj ntsuab, thiab hydrogen los ntawm cov qauv hluav taws xob siv hluav taws xob siv cov dej ntsev. Cov txheej txheem tuaj yeem muab cov ntsiab lus mus ua plaub kauj ruam tseem ceeb, txhua tus tsom rau cov yuam sij tseem ceeb:

 

1. Cov Khoom Siv Raw Pretreatment: Hloov cov ntsev ntsev rau hauv "cov ntsev ntxuav ntsev"
Cov ntsev uas nyoos (muaj ntsev) yog yaj nyob rau hauv cov dej tshiab los tsim cov brine brine, uas yog thawj lim los tshem tawm cov av;
Tshuaj lom neeg cov tshuaj tiv thaiv (xws li sodium carbonate thiab sodium hydroxide thiab sulium hydroxide) yog ntxiv rau tshem tawm cov brine kom tiv thaiv clogging ntawm electrolytic membrane;
Thaum kawg, "ua kom zoo brine" yog lim thiab preheated rau qhov ntsuas kub tsim nyog rau siv.

 

2. Cov qauv electrolysis: hluav taws xob tau thov kom cais cov brine.

Cov khoom ua kom zoo nkauj brine yog pub rau hauv ion {{0} mext txauv membrarane cell, qhov twg ncaj qha rau tam sim no yog siv.

Anode: chloride ions yog hloov mus rau chlorine roj (tawm), thiab seem "brine" yog rov ua dua tshiab rau rov siv dua.

Cathode: Cov lwg dej roj yog hloov mus rau hydrogen gas (tawm), thaum muaj "cov tshuaj soda sodium fydroxide yog tsim tawm (tawm).

Lub ion -} Exchange kev ua yog tso cai rau cornace, tiv thaiv cov tshuaj tiv thaiv los ntawm cov tshuaj tua kab thiab cov tshuaj tawg thiab cov tshuaj chlorine.

Chlorine: dej thiab cua ci ntsa iab tau muab tshem tawm, tom qab ntawd qhuav nrog cov sulfuric acid rau siv ncaj qha lossis muaj liquefied cia.

Hydrogen: Residual Caus Soda so kom deb thiab, tom qab ziab, siv tau los tsim cov roj hydrochloric acid, lossis huv kom muaj kev coj dawb huv.

Caustic Dej Qab Zib: Cov Quav Quav Hluav Taws Xob Yooj Yim (kom tshem tawm cov nplaim hluavtaws ntau dua 99% {% {} Kev tiv thaiv dhau los: txo cov poob thiab muaj kuab paug

Qhov "brine dej" tseem tshuav hluav taws xob yog lub ntsej muag thiab xa rov qab mus rau "cov khoom siv raw pretreatment" theem rau re ... 0}} salting.

Wastewater tsim tawm thaum lub sijhawm tsim khoom (xws li ntxuav dej) yog ib nrab ua dua tom qab kev cuam tshuam thiab kev kho mob, nrog cov qauv kev sib tw.

Impurity precipitates (xws li ntsev sludge) yog lub cev qhuav dej thiab xa mus rau cov chaw pov tseg tshwj xeeb.

 

 

Yuav ua li cas chlor - cov nroj tsuag alkali ua kom muaj kev tsim khoom nyab xeeb thaum lub sijhawm tsim khoom?

 

1. High {{{}}} Cov Khoom Siv Khoom Siv Khoom Siv: Kev tiv thaiv kev pheej hmoo ntawm cov chlorine, hydrogen, thiab alkali

Chlorine: Khaws cia rau hauv siab - Cov hlau hluav taws xob tawm nrog cov tshuaj lom neeg thiab cov khoom siv alkaline Cov neeg ua haujlwm yuav tsum hnav zoo - pa siab lub pa.

Hydrogen: Pipelines / tso tsheb hlau luam / tso tsheb hlau luam rau hluav taws xob zoo li qub thiab tawg}}} Cov kiv cua ua pov thawj yuav tsum tau nruab (kom tiv thaiv kom tawg). Huab cua yuav tsum tau hloov nrog nitrogen (oxygen cov ntsiab lus<0.5%) before use.

Caustic Soda: Khw hauv Corrosion -} istant tso tsheb hlau luam / cov tsev muag khoom. Cov neeg ua haujlwm yuav tsum hnav corrosion -} Cov khaub ncaws tiv thaiv thiab geggles thaum tuav. Daim tawv nqaij yuav tsum tau yaug nrog dej thiab thov nrog boric acid.

 

2. Cov Khoom Siv thiab Txheej Txheem Kev Nyab Xeeb: Tag Nrho-} kev tiv thaiv ua txhaum

Cov khoom siv tseemcub: Cov electrolyzers yuav tsum yauv kev kuaj xyuas rau ion {} Pauv Hloov Membrane (txhawm rau tiv thaiv cov kab mob chlorine thiab hydrogen). Compressors yuav tsum yog roj - ywj nrog kev tiv thaiv kev tiv thaiv. Cov khoom siv tshwj xeeb yuav tsum dhau kev tshawb xyuas txhua xyoo.

Cov qauv tsim: Nruab DCS system rau tiag - lub sijhawm ntsuas kev soj ntsuam (nrog lub tswb ceeb toom rau kev txwv). Ib qho xwm ceev nres (ESD) khawm yuav tsum muab nruab. Cov tshuaj chlorine thiab hydrogen iples yuav tsum tsis txhob hla lossis sib xyaw.

 

3. Cov neeg ua haujlwm tswj hwm: Qauv ua haujlwm + txhim kho kev kawm
Cov neeg ua haujlwm tshiab yuav tsum dhau "peb {{{{{{}}}}}}}}}}}}}}}}}}}}} Kev Nyab Xeeb Kev Nyab Xeeb Kev Kawm Ntawv" kev ntsuas ua ntej noj lawv cov posts. Cov neeg ua haujlwm uas twb muaj lawm yuav tsum nyeem cov txheej txheem kev nyab xeeb thiab xyaum cov txheej txheem teb thaum muaj xwm ceev (xws li tuav tshuaj chlorine txi) txhua xyoo.
Cov txheej txheem ua haujlwm (xws li kaw tawm lub zog thiab txhuav pob hluav taws xob electrolytic ua ntej muab cov hloov pauv. Cov thawj saib xyuas kev nyab xeeb raug xaiv los rau kev ua txhaum cai thiab txhawb kev tshaj tawm txog kev phom sij.

 

4. Kev npaj khomob tam sim no: teb sai sai rau kev kub ntxhov
Cov phiaj xwm tshwj xeeb tshwj xeeb (rau cov tshuaj txhuam hniav kub, kev txav tawm thiab sib xyaw ua ke, thiab sib koom tes nrog thaum muaj xwm txheej ceev / kev tua hluav taws / kev tua hluav taws / kev tua hluav taws / kev tua hluav taws.
Kev cob qhia yog nruab nrog cov khoom siv tsom iav thiab cov khoom siv ceev. Ib lub vane cua nyob hauv cov cheebtsam chlorine cheeb tsam. Cov thawv ntim cov khoom siv thiab cov neeg sawv cev nruab nrab yog cov khoom siv xwm txheej, thiab cov khoom siv thaum muaj xwm txheej ceev yog kuaj xyuas rau kev muaj kev ntseeg siab.

 

5. Ib puag ncig thiab saib xyuas: tiag- lub sijhawm tswj kev pheej hmoo
Cov Retectors (Chlorine thiab Hydrogen) tau teeb tsa ntawm cov chaw tseem ceeb thoob plaws hauv cov nroj tsuag, nrog cov ntaub ntawv txuas nrog lub chaw tswj hwm. Kev soj ntsuam cov ntsiab lus yog nyob hauv qab ntawm cov nroj tsuag kom tiv thaiv kom tsis txhob muaj kev sib kis ntawm thaj chaw ib puag ncig.
Wastewater raug kho kom tau raws li cov qauv rau kev tso tawm / rov ua dua tshiab. Cov khib nyiab, xws li ntsev sludge thiab khib lav week, yog pov tseg ntawm cov chaw tsim nyog thiab tsis muaj pov tseg hauv kev sib cais.
