Waxaa jira laba hab oo warshadeed oo wax soo saarkasoodhaha caustic: causticization iyo electrolysis. Habka causticization waxaa loo qaybiyaa habka causticization ash soodhaha iyo habka causticization alkali dabiiciga ah sida alaabta ceeriin kala duwan; Habka korantada waxaa loo qaybin karaa habka korantada diaphragm iyo habka xuubka beddelka ion.
Habka causticization dambaska soodhaha: dambaska soodhaha iyo lime waxa loo beddelaa xal dambas soodhaha ah iyo dambaska waxa loo beddelaa caano lime siday u kala horreeyaan. Dareen-celinta causticization waxaa lagu fuliyaa at 99-101 ℃. Dareeraha causticization waa la caddeeyey, la uumi baxay oo xoogga saaray in ka badan 40%. Soodhaha caustic ee dareeraha ah. Dareeraha la ururiyey ayaa sii xoogaysanaya oo la adkeeyey si loo helo badeeco adag oo soodhaha ah. Dhoobada wax dhalisa waxaa lagu dhaqaa biyo, biyaha dhaqida waxaa loo isticmaalaa in lagu badalo alkali.
Habka causticization Trona: trona waa la jajabiyey, milmay (ama alkali halogen), la caddeeyey, ka dibna caanaha lime waxaa lagu daraa si ay u causticize at 95 ilaa 100 ° C. Dareeraha causticized waa la caddeeyey, la uumibixiyey, waxaana lagu ururiyey uruurinta NaOH oo ku dhow 46%, dareeraha saafiga ah waa la qaboojiyey. , roobka milixda iyo karkarinta dheeraadka ah si aad u hesho badeecad adag oo soodhaha ah. dhoobada causticized waxaa lagu dhaqaa biyo, biyaha dhaqida waxaa loo isticmaalaa in lagu milo trona.
Habka Electrolysis Diaphragm: ku dar dambaska soodhaha, soodhaha caustic, iyo barium chloride xooga saar si aad meesha uga saarto wasakhda sida calcium, magnesium, iyo sulfate ions ka dib milixdii asalka ahayd ee salinized, ka dibna ku dar sodium polyacrylate ama causticized bran taangiga caddaynta si loo dedejiyo roobka, iyo sifaynta ciidda Ka dib, aashitada hydrochloric ayaa lagu daraa si ay u dhexdhexaadiso. brine waa la sii kululeeyay waxaana loo diraa korantada. Electrolyt-ka waa la sii kululeeyay, la uumi baxay, waxaa loo kala soocay milix, waana la qaboojiyey si loo helo soodhaha dareeraha ah ee dareeraha ah, taas oo dheeraad ah si loo helo badeecada dhammaatay ee soodhaha adag ee adag. Biyaha lagu dhaqo dhoobada milixda waxaa loo isticmaalaa in lagu milo milix.
Habka xuub beddelka Ion: Ka dib markii milixdii asalka ahayd loo beddelo milix, brine ayaa la safeeyey si waafaqsan habka dhaqanka. Ka dib markii brine aasaasiga ah lagu sifeeyo iyada oo loo marayo filter sintered microporous sinteed carbon tubular filter, ka dibna waxaa lagu sifeeyaa mar kale iyada oo loo marayo munaarad resin sarrifka chelating ion si loo sameeyo Marka kalsiyum iyo magnesium content ee brine hoos u dhaco 0. 002%, brine sifayn sare ee labaad waa electrolyzed. in laga dhaliyo gaaska chlorine qolka anode-ga. Na+ ee brine ee qolka anode-ku wuxuu ka galaa qolka cathode iyada oo loo marayo xuubka ion iyo OH- ee qolka cathode wuxuu soo saaraa sodium hydroxide. H+ si toos ah ayaa loogu sii daayaa cathode si loo dhaliyo gaasta hydrogen. Inta lagu jiro habka korantada, qadar ku habboon oo ah hydrochloric acid oo nadiif ah ayaa lagu daraa qolka anode si loo baabi'iyo OH-, iyo biyaha saafiga ah ee loo baahan yahay waa in lagu daraa qolka cathode. Soodhaha soodhaha ee nadiifka ah ee nadiifka ah ee ka soo baxa qolka cathode waxay leedahay fiirsashada 30% ilaa 32% (mass), taas oo si toos ah loogu isticmaali karo alaab alkali ah oo dareere ah, ama waxaa lagu sii kordhin karaa si loo soo saaro alaab adag oo soodhaha ah.
