Product process

Iyo EDI tekinoroji inzira nyowani yekubvisa munyu inosanganisa electrodialysis uye ion exchange.Iyi nzira inotora mukana wemasimba ezvese electrodialysis uye ion exchange uye inotsiva kusimba kwavo.Inoshandisa ion exchange kune yakadzika desalinate kuti ikunde dambudziko rekusakwana kwemvura kunokonzerwa ne electrodialysis polarization.Inoshandisawo electrodialysis polarization kugadzira H+ uye OH- ions ye otomatiki resin regeneration, iyo inokunda kushata kwemakemikari kugadzirwazve mushure mekutadza kweresin.Naizvozvo, tekinoroji yeEDI inzira yakakwana yekubvisa salination.

Munguva yeEDI desalination process, maion ari mumvura anochinjaniswa nemaioni ehydrogen kana hydroxide ions muion exchange resin, zvino maion aya anobva aenda mumvura yakanyura.Iyi ion exchange reaction inoitika mukamuri yemvura yakanyungudika yeyuniti.Mukamuri yemvura yakanyungudika, maion hydroxide ari muanion exchange resin exchange nemaanioni ari mumvura, uye maion ehydrogen ari mucation exchange resin exchange nemacations ari mumvura.Ioni dzakatsinhaniswa dzinobva dzatama pamusoro pemabhora eresin pasi pekuita kweDC magetsi emagetsi uye kupinda mukamuri yemvura yakadzika kuburikidza nekutsinhana kweion.

Maanioni anochajiwa zvisina kunaka anokwezvwa kune anode uye anopinda mukamuri yemvura yakatarisana nemukati memembrane yeanion, nepo iyo iri padyo ne membrane inodzivirira kuti isapfuure uye inovharira aya maion mumvura yakadzika.Positively charged cations inokwezvwa kune cathode uye inopinda mukamuri yakatarisana yakadzika yemvura kuburikidza ne cation membrane, nepo anion membrane iri padyo inovadzivirira kuti vasapfuure uye inovharira aya maion mumvura yakadzika.

Mumvura yakadzikama, maion kubva kumativi ose anochengetedza kusarerekera kwemagetsi.Zvichakadaro, ikozvino uye ion kutama kwakaenzana, uye ikozvino ine zvikamu zviviri.Chimwe chikamu chinobva mukutama kwemaioni akabviswa, uye chimwe chikamu chinobva mukutama kwemaioni emvura anoisa muH+ neOH-ions.Kana mvura ichipfuura nepakati pemvura yakanyungudutswa uye yakadzika makamuri emvura, iyo ion zvishoma nezvishoma inopinda mukamuri yakatarisana yemvura uye inotakurwa kunze kweiyo EDI unit nemvura yakadzika.

Pasi peiyo yakakwira voltage gradient, mvura inogezwa nemagetsi kuburitsa huwandu hukuru hweH+ neOH-, uye idzi panzvimbo-saiti dzakagadzira H+ neOH- dzichiramba dzichigadzira resin inotsinhana ion.Naizvozvo, iyo ion exchange resin muchikamu cheEDI haidi kuvandudzwa kwemakemikari.Iyi ndiyo EDI desalination process.
