Hose ea ion-exchange membrane electrolyzer
Karolo ea Electrolysis: Hose ea Electrolyzer
a. Sistimi ea Anolyte
The super purified brine ho tloha ka tankeng ea brine e hloekisitsoeng ka ho fetisisa e fepeloa ka mokhoa o mong le o mong oa electrolyzer ebe o fetisetsoa kamoreng e 'ngoe le e' ngoe ea anode moo e senyehang ho ba chlorine le sodium ion. Selaoli sa phallo se nang le phaephe ea phepelo ea brine ho potoloho e 'ngoe le e 'ngoe ea electrolyzer se hlokomela sekhahla sa phallo ea brine e hloekisitsoeng haholo.
Mokhahlelo oa mekhahlelo e 'meli oa brine e senyehileng le khase e metsi ea chlorine e phalla ho tloha phaposing e 'ngoe le e' ngoe ea anode ho ea pokellong e mengata e nang le elektrolyzer e 'ngoe moo brine e felileng le khase ea chlorine li arohanang.
Mokelikeli o senyehileng o tsoang ho manifold o phalla ka pipe ea lekala le hlooho e kholo ho ea tanka ea anolyte ka matla a khoheli, ha khase ea chlorine e romeloa B/L (karolo ea ho sebetsa ha khase ea chlorine).
Mokelikeli o senyehileng o tsoang tanka ea anolyte o pompeloa karolong ea dechlorination ka molaoli oa boemo. E 'ngoe ea brine e felileng ka tanka ea anolyte e khutlisetsoa ho li-electrolyzer ka ho tsoakoa le brine e ncha e hloekisitsoeng haholo.
Mohala oa phepelo ea metsi a nang le demineralized o fanoa bakeng sa dilution ea anolyte ho thibela kristale ea letsoai nakong ea ho koala le bakeng sa tokiso ea mahloriso a anolyte ho fihlela tlhokahalo ea membrane nakong ea ho qala.
b. Sistimi ea Catholyte
Recycle caustic e feptjoa ho e 'ngoe le e' ngoe ea electrolyzer e mengata ka mochine oa mocheso oa catholyte, ebe e abeloa kamore e 'ngoe le e' ngoe ea cathode moo cathode reaction e senyang metsi ka har'a hydrogen le ion hydroxide. Selaoli sa phallo se kentsoeng potolohong e 'ngoe le e 'ngoe ea electrolyzer se laola sekhahla sa phallo ea caustic.
Motsoako oa mekhahlelo e 'meli oa tharollo ea caustic le khase ea haedrojene e phalla ho tloha kamoreng e' ngoe le e 'ngoe ea cathode ho ea ho pokello e mengata e nang le electrolyzer e' ngoe le e 'ngoe moo tharollo ea caustic le hydrogen li arohaneng.
Tharollo ea caustic e tsoang ho manifold e phalla ka pipe ea lekala, 'me sehlooho se seholo se kena tanka ea catholyte ka matla a khoheli, ha khase ea hydrogen e romeloa karolong ea ho sebetsa ha khase ea hydrogen ka lekala le phala ea hlooho. Ha u tloha tanka ea recycle caustic, tharollo ea caustic e arohana ka melapo e 'meli: molapo oa sehlahisoa ho ea ho B / L le ho tsosolosa metsi a caustic ho li-electrolyzers.
Caustic soda heat exchanger e futhumatsa kapa e pholisa caustic e tsosolositsoeng ho boloka mocheso o sebetsang oa electrolyzer ho 85 ~ 90 deg-C. Nakong ea ho qala, sesebelisoa sa mocheso sa caustic soda se sebelisetsoa ho futhumatsa electrolyte ka har'a li-electrolyzer, ho potlakisa ho fumana mojaro oa hona joale ntle le motlakase o feteletseng.
Matla a caustic a electrolyzer a beoa leihlo ke sesupo sa caustic density, 'me hangata a bolokoa ho hoo e ka bang 32wt%, e leng sebaka se nepahetseng sa tšebetso ea membrane, ka ho laola bongata ba phepelo ea metsi e kentsoeng ka har'a molapo o tsosolositsoeng oa caustic.
Ho bona ho se tloaelehe ha li-electrolyzers, motlakase oa electrolyzer le sistimi ea tlhahlobo ea mocheso e kentsoe.
c. Tsamaiso ea khase
Khatello ea khase ea haedrojene e laoloa ka hoo e ka bang. 400 mm H2O e phahameng ho feta khatello ea khase ea chlorine.
