I-chlorine alkali electrolysis yenziwa ngezinqubo ezimbili: i-diaphragm kanye nenqubo ye-membrane, laphoamanzi ahlanzekileukuqapha okugxilile kubalulekile ekuthuthukiseni izinqubo. Ama-brine, avame ukuqukatha amazinga aphezulu e-sodium chloride (NaCl) namanye ama-ion, acutshungulwa ngamasu afana ne-electrodialysis yokuhlanza i-brine kanye ne-chlorine alkali electrolysis.
Izinselelo ezifana nezilinganiso ezingaguquki, ukungasebenzi kahle kwenzwa, kanye nokusetshenziswa kwamandla okuphezulu kungakhinyabeza ukusebenza kahle. Ngaphezu kwalokho, impilo yolwelwesi izothinteka ngenxa yokungcola kwemishini kanye nosawoti we-calcium noma we-magnesium, ovala izimbotshana ezinhle ze-diaphragma noma ulwelwesi ngesikhathi se-electrolysis.
I-Lonnmeter, umhlinzeki wezixazululo onolwazi futhi engumkhiqizi oholayo wamamitha okugxilisa asemgqeni, inikeza izixazululo eziningi zokucubungula onjiniyela, abaphathi bokusebenza, nezingcweti zokulawula ikhwalithi abafuna izinzwa zokugxilisa amanzi ezinosawoti ezinokwethenjelwa nezisetshenziswa ezisetshenziselwa ukunquma ukugcwala kwe-brine ukubhekana nalezi zinkinga. Qhubeka ufunde ukuze uthole ukuthi amasistimu okuqapha athuthukile angashintsha kanjani imisebenzi yakho.
Ukuqonda Ukuhlanzwa Kwe-Brine Nezinselele Zokugxila
Iyini i-Brine Purification?
Ukuhlanzwa kwe-brine kuyinqubo yokwelapha izixazululo ze-saline ukususa ukungcola, okufana nama-divalent ion (Ca²⁺, Mg²⁺), i-organic matter, nezinhlanganisela zokukala njenge-calcium sulfate (CaSO₄). Kuyinqubo ebucayi ezimbonini ezifana nokuhlanzwa kwe-chloralkali brine kanye nokuhlanzwa kwe-sodium chloride brine, lapho i-high-purity brine ibalulekile kunqubo ye-chloralkali ephumelelayo. Ubuchwepheshe obufana ne-electrodialysis (ED) kanye ne-electrodialysis reversal (EDR) busetshenziswa kabanzi ukugxilisa amanzi anosawoti ngenkathi kuhlukaniswa ama-ion aqondiwe. Kodwa-ke, ukulawulwa okunembile kokugcwala kwe-brine ezinqubweni ze-chlor alkali kubalulekile ukuze kugwenywe ukungasebenzi kahle, njengokukhuphuka kokusetshenziswa kwamandla noma ikhwalithi yomkhiqizo esengozini.
Amaphuzu Obuhlungu ku-Brine Concentration Measurement
Ukuphazamiseka Kokwakheka Kwe-Brine Eyinkimbinkimbi
Ama-brine asuka emanzini olwandle ahlehla i-osmosis noma izinqubo zezimboni ngokuvamile aqukethe inhlanganisela ye-monovalent (Na⁺, Cl⁻) nama-ion ahlukanisiwe (Ca²⁺, Mg²⁺, SO₄²⁻), kanye nezinto eziphilayo nezinhlanganisela zokukala njenge-silica. Lezi zingxenye ziphazamisa izinzwa zokuhlushwa kwe-brine, okuholela ekufundweni okungalungile. Isibonelo, ama-conductivity probe, ajwayele ukusetshenziselwa ukulinganisa ukugxiliswa kwamanzi, angase ahumushe kabi amasiginali ngenxa ye-divalent ion noma ukungcola okuphilayo, enze kube nzima ukuqapha ngesikhathi sangempela ekuhlanzweni kwe-brine electrodialysis.
Ukungasebenzi kahle kanye nokukala kuzinzwa
Amanzi anosawoti omningi, ngokuvamile afinyelela ku-180–200 g/L ingqikithi yezinto eziqinile ezincibilikisiwe, abangela ukungcola kanye nokwenyuka kweziqaphi zokugxilisa amanzi anosawoti njengama-conductivity probe noma ama-electrode akhetha i-ion. Izinhlanganisela zokukala ezifana ne-calcium carbonate noma i-sulfate yakheka endaweni yezinzwa, enciphisa ukunemba futhi edinga ukulungiswa njalo. Ekuhlanzweni kwe-chlor alkali brine, lokhu kuholela ekwenyukeni kwesikhathi kanye nezindleko, ngisho nokuguqulwa kwe-electrodialysis okunciphisa ukungcoliswa kolwelwesi.
I-Concentration Polarization Effects
Ku-electrodialysis yokuhlanza amanzi, ukugxilwa kwe-polarization eduze nolwelwesi lwe-ion-exchange kudala ukuhluka kokugxilwa kwe-ion yendawo, okwenza kube nzima ukukala ukugcwala kwe-brine ngobuningi bangempela. Lokhu kuyinkinga ikakhulukazi ekuminyaneni okuphezulu kwamanje, lapho ukufuduka kwe-ion kukhulisa ukuhlukaniswa kwe-polarization, okuholela ekufundweni okuguquguqukayo kusuka kumathuluzi asetshenziselwa ukunquma ukugcwala kwe-brine.
Izixazululo Zokuqapha Ukugxila Kwe-Brine Okuphumelelayo
Sethula i-Brine Concentration Monitor ku-Production Line
Okuthuthukileiziqaphi zokuhlushwa kwe-brineukugxila kwe-brine ngesikhathi ukuvimbela ukungcola kusengaphambili. Bese unciphisa ukukala kusuka ku-calcium sulfate noma i-carbonate, wehlise imvamisa yokulungisa ezinqubweni zokuhlanza amanzi. I-Lonnmeterimitha yokuhlushwa ye-ultrasoniciyasebenza esilinganisweni sesikhathi sangempela sokuhlushwa ku-electrodialysis yokuhlanza amanzi.
Ifaka isivinini somsindo ngokulinganisa isikhathi sokudlulisa segagasi lomsindo ukusuka emthonjeni wesignali kuya kumamukeli wesignali. Le ndlela yokulinganisa ayithinteki ekuphatheni, umbala nokucaca koketshezi, okuqinisekisa ukwethembeka okuphezulu kakhulu. Abasebenzisi bangafinyelela ukunemba kokulinganisa kwe-5 ‰, 1 ‰, 0.5 ‰.
In-Line Pretreatment Systems
Ukusebenzisa ukwelashwa kwangaphambili okusemgqeni ukuze kukhishwe izinhlanganisela zokukala (isb, i-CaSO₄, i-silica) ngaphambi kwe-electrodialysis yokuhlanza i-brine kunciphisa ukungcoliswa kwezinzwa futhi kuthuthukisa ukunemba kokulinganisa. Amasistimu okwelapha kusengaphambili, afana ne-nanofiltration noma imvula yamakhemikhali, aqinisekisa ukuthi i-brine ehlanzekile ingena enqubweni ye-ED, izuzisa kokubili izinzwa nolwelwesi.
Intelligent Monitoring Systems
Ukuhlanganisa izinzwa zokugxilisa amanzi e-brine ngesikhathi sangempela nezindleko ezilinganiselwe zokuhlaziya ungaxhunyiwe ku-inthanethi ngezikhathi ezithile kanye nokunemba. Nakuba izindlela ezithuthukisiwe ezifana ne-ICP-OES zingasebenzi ekuqapheni okuqhubekayo, zinikeza idatha enembayo ephezulu yokulinganisa, iqinisekisa ukulawulwa okuthembekile kokuhlushwa kwe-brine ezinqubweni ze-chlor alkali.
Ukulawulwa Kwenqubo Okuthuthukisiwe ngezibalo
Ukuhlaziywa kwedatha yesikhathi sangempela nokufunda komshini kungalungisa imiphumela ye-polarization ye-concentration futhi kuthuthukise ukuthembeka kwesikali. Ngokuhlaziya idatha yezinzwa eduze nemingcele yenqubo, lezi zinhlelo zithuthukisa ukuqapha kokuhlushwa kwe-brine ngaphandle kwehadiwe eyengeziwe, ehlisa ukusetshenziswa kwamandla nezindleko.
Imibuzo Evame Ukubuzwa
Iyini i-Brine Purification?
Ukuhlanzwa kwamanzi kuhilela ukususa ukungcola ezixukwini ezinosawoti ukuze kukhiqizwe amanzi ahlanzekile aphezulu ukuze asetshenziswe ezimbonini njenge-chlor alkali brine purification noma i-electrodialysis yokuhlanza amanzi. Iqinisekisa izinqubo ezisebenzayo kanye nemiphumela yekhwalithi ephezulu ngokusebenzisa ubuchwepheshe obufana ne-ED ukugxilisa ingqondo nokuhlanza amanzi.
Yiziphi Izinsimbi Ezisetshenziswa Ukunquma Ukugxilwa Kwe-Brine?
Amathuluzi avamile asetshenziselwa ukunquma ukugxiliswa kwe-brine ahlanganisa ama-conductivity probe, ama-electrode akhethwa yi-ion, namathuluzi okuhlaziya athuthukile njenge-ion chromatography. Ama-conductivity probe awabizi kakhulu kodwa awakhethi, kuyilapho ama-electrode akhetha i-ion anikeza ukunemba kwama-ion athile esilinganisweni sokuhlushwa kwe-brine.
Ngingabhekana Kanjani Nezinkinga Zokugxilwa Kwe-Brine?
Izinkinga zokugxilisa i-brine ezifana nokungcolisa, ukuhlukanisa, noma ukuphazamiseka kungaxazululwa ngenzwa yokuhlushwa ye-ultrasonic, ukwelashwa kwangaphambili okusemgqeni, nokuguqulwa kwe-electrodialysis. Amasistimu okuqapha ama-Hybrid kanye nokuhlaziya okuthuthukile kuqhubekisela phambili ukunemba nokusebenza kahle ezinqubweni zokuhlanzwa kwamanzi.
Ukuqapha okusebenzayo kwe-brine kubalulekile ukuze kuthuthukiswe ukuhlanzeka kwamanzi ahlanzekile ekukhishweni kukasawoti emanzini, i-chlor-alkali, nezimboni zokuhlanza amanzi angcolile. Ngokubhekana namaphuzu obuhlungu afana nokuqanjwa kwe-brine eyinkimbinkimbi, i-sensor fouling, nemiphumela ye-polarization yokuhlushwa, izinzwa ezithuthukisiwe zokuhlushwa kwe-brine kanye namasu okuthuthukisa inqubo kungathuthukisa kakhulu ukusebenza kahle nokunciphisa izindleko.
Xhumana nomhlinzeki othembekile we-Lonnmeter wama-monitor concentration namuhla ukuze ucele ikhotheshini noma idemo futhi ulawule ukusebenza kwakho.
