I-resin yombhede oxubene namanzi ahlanzekile yakhiwe ngohlobo lwe-gel oqinile i-acid cation exchange resin kanye ne-resin eqinile ye-alkali anion exchange resin, futhi ivuselelwe futhi yahlanganiswa ngomumo.
Kusetshenziswa ikakhulukazi ekuhlanzweni okuqondile kwamanzi, ukulungiswa kwamanzi amsulwa embonini ye-elekthronikhi, kanye nokwelashwa okulandelayo okuxubene nokwelashwa okuhle kwezinye izinqubo zokwelashwa kwamanzi. Ifanele imikhakha eyahlukahlukene yokwelashwa kwamanzi enezidingo eziphakeme zamanzi futhi ngaphandle kwezimo zokuvuselelwa okuphezulu, njengemishini yokubonisa, i-hard disk yokubala, i-CD-ROM, ibhodi lesifunda elinemba, imishini ehlukile ye-elekthronikhi neminye imboni yemikhiqizo kagesi eqondile, imithi nokwelashwa, imboni yezimonyo, imboni yemishini yokunemba, njll

I-Mixed embhedeni resin isetshenziswa kakhulu embonini yokuhlanzwa kwamanzi ngenqubo yokupholisha amanzi ukufeza ikhwalithi yamanzi yedineralization (efana ne-reverse osmosis system). Igama lombhede oxubekile lifaka i-resin eqinile ye-asidi cation exchange kanye ne-resin resin exchange resin eqinile.
Umsebenzi we-Mixed Bed Resin
Ukwenza i-deionization (noma ukwehliswa kwe-demineralization) kusho kuphela ukususwa kwama-ion. Ama-ion akhokhiswa ama-athomu noma ama-molecule atholakala emanzini anezindleko ezingekho emthethweni noma ezinhle. Ezinsizeni eziningi ezisebenzisa amanzi njenge-ejenti yokuhlanza noma ingxenye, la ma-ion abhekwa njengangcolile futhi kufanele asuswe emanzini.
Ama-ion akhokhiswa kahle abizwa ngokuthi ama-cation, kanti ama-ion akhokhiswe kabi abizwa ngama-anion. Izinhlaka zokushintshaniswa kwe-Ion zishintshanisa ama-cations angafuneki nama-anion nge-hydrogen ne-hydroxyl ukwakha amanzi amsulwa (H2O), okungeyona i-ion. Okulandelayo uhlu lwama-ion ajwayelekile emanzini kamasipala.
Isimiso sokusebenza se-Mixed Bed Resin
Izinhlaka zemibhede ezixutshiwe zisetshenziselwa ukukhiqiza amanzi adonswa ngamanzi (adonswe ngamaminerali noma "Di"). Lawa ma-resin angobuhlalu obuncane bepulasitiki abakhiwe ngamaketanga e-organic polymer namaqembu asebenzayo akhokhisiwe afakwe ebuhlalu. Iqembu ngalinye elisebenzayo linenkokhiso emisiwe noma engemihle elungisiwe.
Izinhlaka ze-Cationic zinamaqembu asebenzayo angalungile, ngakho-ke ziheha ama-ion akhokhiswa kahle. Kunezinhlobo ezimbili zama-resin e-cation, i-acid cation ebuthakathaka (WAC) ne-acid cation enamandla (SAC). I-resin ye-acid cation ebuthakathaka isetshenziselwa ikakhulukazi ukwenza i-dealkalization nezinye izinhlelo zokusebenza ezihlukile. Ngakho-ke, sizogxila endimeni ye-resin eqinile ye-acid cation esetshenzisiwe ekukhiqizeni amanzi akhethiwe.
Izinhlayiya ze-Anionic zinamaqembu amahle asebenzayo ngakho-ke ziheha ama-ion akhokhiswe kabi. Kunezinhlobo ezimbili zama-resin anion; I-anion base ebuthakathaka (i-WBA) ne-anion base enamandla (i-SBA). Zombili lezi zinhlobo zama-resin anionic zisetshenziselwa ukukhiqizwa kwamanzi akhethiwe, kepha zinezici ezihlukile ezilandelayo:
Lapho isetshenziswa ohlelweni lombhede oluxubekile, i-WBA resin ayikwazi ukususa i-silica, i-CO2 noma inekhono lokunciphisa ama-acid abuthakathaka, futhi ine-pH ephansi kunokungathathi hlangothi.
I-resin yombhede oxubile isusa zonke izinyoni kule thebula elingenhla, kufaka phakathi i-CO2, futhi ine-pH ephakeme kune-neutral uma isetshenziswa ohlelweni lombhede ozimele olubili ngenxa yokuvuza kwe-sodium.
Izinhlaka zeSac nezeSBA Zisetshenziswa Embhedeni Ohlanganisiwe.
Ukuze kukhiqizwe amanzi akhethiwe, i-resin ye-cation ivuselelwa kabusha nge-hydrochloric acid (HCl). I-Hydrogen (H +) ishajiwe kahle, ngakho-ke iyazinamathisela ebuhlalu be-resin ye-cationic eshajiwe kabi. I-resin ye-anion yenziwa kabusha nge-NaOH. Amaqembu e-Hydroxyl (OH -) akhokhiswa kabi futhi azinamathisela ebuhleni be-anionic resin.
Ama-ion ahlukile adonswa kobuhlalu be-resin ngamandla ahlukile. Isibonelo, i-calcium iheha ubuhlalu be-cationic resin ngokuqinile kune-sodium. I-hydrogen ebuhlalu be-cationic resin ne-hydroxyl ebuhlalu be-anionic resin ayinakho ukuheha okuqinile kobuhlalu. Kungakho ukuvunyelwa kwe-ion kuvunyelwe. Lapho i-cation ekhokhiswa kahle igeleza phakathi kobuhlalu be-cationic resin, ukushintshaniswa kwe-cation yi-hydrogen (H +). Ngokufanayo, lapho i-anion enecala elibi igeleza phakathi kobuhlalu be-anion resin, i-anion iyashintshana ne-hydroxyl (OH -). Uma uhlanganisa i-hydrogen (H +) ne-hydroxyl (OH -), wakha i-H2O emsulwa.
Ekugcineni, zonke izingosi zokushintshana ku-cation nobuhlalu be-anion resin zisetshenzisiwe, futhi ithangi alisawakhiqizi amanzi ahlanzekile. Kuleli qophelo, ubuhlalu be-resin budinga ukuvuselelwa ukuze busetshenziswe kabusha.
Kungani ukhetha i-resin yombhede oxubekile?
Ngakho-ke, okungenani izinhlobo ezimbili zama-resin exchange resins ziyadingeka ukulungiselela amanzi e-ultrapure ekwelashweni kwamanzi. I-resin eyodwa izosusa ama-ion akhokhiswe kahle bese enye isusa ama-ion akhokhiswe kabi.
Kuhlelo lombhede oluxubekile, i-cationic resin ihlala isendaweni yokuqala. Lapho amanzi kamasipala engena ethangini eligcwele i-cation resin, wonke ama-cation akhokhiswa kahle ahehwa ubuhlalu be-cation resin bese beshintshaniswa nge-hydrogen. Izinyoni ezinecala elibi ngeke zihehwe futhi zidlule ebuhlalu be-cationic resin. Isibonelo, ake sihlole i-calcium chloride emanzini okuphakelayo. Esisombululo, ama-calcium ions akhokhiswa kahle futhi azinamathisela ebuhlalu be-cationic ukukhipha i-hydrogen ions. I-chloride inenkokhiso engemihle, ngakho-ke ayizihlanganisi nobuhlalu be-cationic resin. I-Hydrogen enamanani amahle inamathela ku-chloride ion ukwakha i-hydrochloric acid (HCl). Okungcoliswa okuvela kumphathi wesaka kuzoba ne-pH ephansi kakhulu futhi kube nokuqhuba okuphezulu kakhulu kunamanzi okuphakelayo angenayo.
Ukungcola kwe-resin ye-cationic yakhiwe nge-asidi enamandla ne-asidi ebuthakathaka. Ngemuva kwalokho, amanzi e-asidi azongena ethangini eligcwele i-anion resin. Izinhlayiya ze-Anionic zizoheha ama-anion akhokhiswe kabi njengama-chloride ions bese ziwashintshanisa ngamaqembu e-hydroxyl. Umphumela uba yi-hydrogen (H +) ne-hydroxyl (OH -), eyakha i-H2O
Eqinisweni, ngenxa "yokuvuza kwe-sodium", uhlelo lombhede oluxubekile ngeke lukhiqize i-H2O yangempela. Uma ukuvuza kwe-sodium ethangini lokushintshana le-cation, lihlangana ne-hydroxyl ukwakha i-sodium hydroxide, enokusebenza okuphezulu. Ukuvuza kwe-sodium kwenzeka ngoba i-sodium ne-hydrogen inokuheha okufana kakhulu nobuhlalu be-cationic resin, futhi kwesinye isikhathi ion ye-sodium ayizishintshi i-hydrogen ions uqobo.
Kuhlelo lombhede oluxubekile, i-acid cation eqinile ne-base base anion resin ixubene ndawonye. Lokhu kwenza ukuthi ithangi lombhede elihlanganisiwe likwazi ukusebenza njengezinkulungwane zamayunithi ombhede ahlanganisiwe ethangini. Ukushintshaniswa kwe-cation / anion kwaphindwa embhedeni we-resin. Ngenxa yenani elikhulu lokushintshaniswa okuphindaphindiwe kwe-cation / anion, inkinga yokuvuza kwe-sodium yaxazululwa. Ngokusebenzisa umbhede oxubekile, ungakhiqiza amanzi asezingeni eliphakeme kakhulu akhishwe emanzini.
