I-resin ebhedini yamanzi amsulwa kakhulu yenziwa ngohlobo lwe-asidi olomeleleyo lokutshintshiselana nge-cation resin kunye nentlaka eyomeleleyo ye-alkali anion resin, kwaye iphinde yavuselelwa kwaye yaxutywa.
Isetyenziswa ikakhulu ekuhlanjululeni amanzi ngokuthe ngqo, ukulungiswa kwamanzi acocekileyo kumzi-mveliso we-elektroniki, kunye nonyango olulandelayo lweebhedi oluxubileyo nezinye iinkqubo zonyango lwamanzi. Ilungele imimandla eyahlukeneyo yokunyanga amanzi eneemfuno eziphezulu zamanzi amdaka kwaye ngaphandle kwemeko zokuphinda zenziwe ngokutsha, ezinje ngezixhobo zokubonisa, isixhobo sokubala esinzima, i-CD-ROM, ibhodi yesekethe echanekileyo, izixhobo zombane ezikhethekileyo kunye nolunye uveliso lwemveliso ye-elektroniki, amayeza kunye nonyango. Icandelo lezithambiso, ishishini lokuchaneka ngokuchanekileyo, njl

Intlaka ebhedini Mixed ubukhulu becala kusetyenziswa kushishino zokucoca amanzi inkqubo ipolishi amanzi ukuphumeza demineralization umgangatho wamanzi (ezifana emva inkqubo umva umva osmosis). Igama lebhedi elixubekileyo liquka i-asidi ye-asidi yokutshintshiselana nge-cation resin kunye ne-resion exchange resion.
Umsebenzi we-Resed Bed Resin
Ukuchithwa (okanye ukutywinwa) kuthetha kuphela ukususwa kweeon. Ions zihlawuliswa iiathom okanye iimolekyuli ezifumaneka emanzini zinexabiso elibi okanye iintlawulo ezilungileyo. Kwizicelo ezininzi ezisebenzisa amanzi njengearhente yokuhlanjululwa okanye icandelo, ezi ion zithathwa njengokungcola kwaye kufuneka zisuswe emanzini.
Ii-ion ezihlawuliswe kakuhle zibizwa ngokuba zii-cations, kwaye ii-ion ezingabizi mali zibizwa ngokuba zi-anion. Ion exchange resins exchange cations ezingafunekiyo kunye neeayoni ngehydrogen kunye nehydroxyl ukwenza amanzi amsulwa (H2O), engeyoyoni. Oku kulandelayo luluhlu lweeon eziqhelekileyo emanzini kamasipala.
Umgaqo wokuSebenza we-Resed Bed Resin
Iindidi zebhedi ezixutyiweyo zisetyenziselwa ukuvelisa amanzi asuswe emzimbeni (adityaniswe nedineralized okanye "Di"). Ezi ntlanzi zincinci zincinci zeplastiki ezenziwe ngamaketanga epolymer ephathekayo kunye namaqela asebenzayo ahlawuliswe kwiibhondi. Iqela ngalinye elisebenzayo linentlawulo echanekileyo okanye engalunganga.
IiCinsic resins zinamaqela asebenzayo amabi, ke oko kutsala ii-ion ezihlawulisiweyo. Zimbini iintlobo zentlaka yecation, i-acid cation ebuthathaka (i-WAC) kunye ne-acid cation eyomeleleyo (SAC). I-resin ye-asidi ye-asidi isetyenziselwa ukusetyenziswa kwe-dealkalization kunye nezinye izicelo ezizodwa. Ke ngoko, siza kugxila kwindima yentsimbi eyomeleleyo yeasidi esetyenziselwa ukuvelisa amanzi angcolileyo.
Ii-resin zeAnionic zinamaqela asebenzayo kwaye ke ngoko zitsala ii-ion ezihlawuliswe kakubi. Zimbini iintlobo zentlaka ye-anion; Isiseko se-anion esibuthathaka (i-WBA) kunye nesiseko esomeleleyo se-anion (SBA). Zombini ezi ntlobo zentlaka ye-anionic zisetyenziselwa ukuvelisa amanzi akhutshiweyo, kodwa zinezi zinto zilandelayo:
Xa isetyenziswa kwinkqubo yebhedi exubekileyo, i-resin ye-WBA ayinakususa i-silica, i-CO2 okanye inesakhono sokunciphisa ii-asidi ezibuthathaka, kwaye ine-pH esezantsi kuneyokungathathi hlangothi.
I-resin ebhedi exubeneyo isusa zonke i-anion kule theyibhile ingentla, kubandakanya ne-CO2, kwaye ine-pH ephezulu kune-cala xa isetyenziswa kwinkqubo yebhedi ezimeleyo ngenxa yokuvuza kwesodiyam.
Iisaka kunye ne-SBA Resins zisetyenziswa ebhedini exubekileyo.
Ukuvelisa amanzi akhutshiweyo, i-resin ye-cation ivuselelwa nge-hydrochloric acid (HCl). I-Hydrogen (H +) ihlawuliswe ngokuqinisekileyo, ngoko ke iyazincamathelisa kwi-resin cationic beads. I-anion resin yavuselelwa kunye ne-NaOH. Amaqela e-Hydroxyl (i-OH -) ahlawuliswe kakubi kwaye azincamathele kwi-resion anonyic ngokuqinisekileyo.
Ii-ions ezahlukileyo zitsaleleka kwimbonakalo yentlaka enamandla ahlukileyo. Umzekelo, i-calcium itsala ubuhlalu be-resin ye-cationic ngamandla ngakumbi kune-sodium. I-hydrogen kwi-resin cationic beads kunye ne-hydroxyl kwi-anionic resad beads ayinanto ekhangayo kwiintsimbi. Kungenxa yoko le nto i-ion exchange ivunyelwe. Xa i-cation ehlawuliswe ngokuqinisekileyo igeleza kwi-cationic resad beads, utshintshiselwano lwe-cation yi-hydrogen (H +). Kwangokunjalo, xa i-anion enexabiso elibi iqukuqela kwi-anion resad beads, i-anion exchange kunye ne-hydroxyl (OH -). Xa udibanisa i-hydrogen (H +) ne-hydroxyl (OH -), wenza i-H2O emsulwa.
Okokugqibela, zonke iisayithi zotshintshiselwano kwi-cation kunye ne-anion resad beads zisetyenzisiwe, kwaye itanki ayisasebenzi ngamanzi angcolileyo. Okwangoku, ubuhlalu be-resin kufuneka buvuselelwe ukuze busetyenziswe kwakhona.
Kutheni ukhetha i-resin yebhedi edibeneyo?
Ke ngoko, ubuncinci zimbini iintlobo zeeon resins zotshintshiselwano ziyafuneka ukulungiselela amanzi e-ultrapure kunyango lwamanzi. I-resin enye iya kususa ii-ions ezihlawuliswe ngokuqinisekileyo kwaye enye isuse ii-ion ezihlawuliswe kakubi.
Kwinkqubo ebhedini exubeneyo, i-cationic resin ihlala ikwindawo yokuqala. Xa amanzi kamasipala engena etankini ezaliswe yicin resin, zonke iiteksi ezihlawuliswe kakuhle zitsalelekile kumaso e-resin kwaye atshintshiselwa nge-hydrogen. Ii-anion ezinexabiso elibi azizukutsalwa kwaye zidlule kwi-cationic resad beads. Umzekelo, makhe sijonge i-calcium chloride emanzini okondla. Kwisisombululo, ii-ioni zekhalsiyam zihlawuliswe ngokuqinisekileyo kwaye ziyazincamathelisa kubuhlalu be-cationic ukukhupha ion ye-hydrogen. I-chloride inentlawulo engalunganga, ngoko ke ayizincamathisi kwi-cationic resad beads. I-Hydrogen enentlawulo elungileyo iyazincamathisela kwi-chloride ion ukwenza i-hydrochloric acid (HCl). Amanzi amdaka avela kwisiguquli sesingxobo aya kuba ne-pH esezantsi kakhulu kunye nokuqhuba okuphezulu kakhulu kunamanzi okutya angenayo.
Amanzi amdaka e-resin ye-cationic yenziwe nge-asidi eyomeleleyo kunye ne-asidi ebuthathaka. Emva koko, amanzi aneasidi aya kungena kwitanki ezaliswe yintlaka ye-anion. Ii-resin ze-Anionic ziya kutsala ii-anion ezihlawuliswe kakubi ezifana nee-chloride ion kwaye zitshintshisane ngamaqela e-hydroxyl. Isiphumo yi-hydrogen (H +) kunye ne-hydroxyl (OH -), eyenza i-H2O
Ngapha koko, ngenxa "yokuvuza kwesodiyamu", inkqubo yebhedi exubeneyo ayizukuvelisa i-H2O yokwenyani. Ukuba ukuvuza kwesodiyam kwitanki yotshintshiselwano nge-cation, idityaniswa nehydroxyl ukwenza isodiyam hayidroksayidi, enokuqhuba okuphezulu. Ukuvuza kwesodium kwenzeka ngenxa yokuba isodiyam kunye nehydrogen zinomtsalane ofanayo kwi-cationic resad beads, kwaye ngamanye amaxesha ion i-sodium ayitshintshisi ion hydrogen.
Kwinkqubo yokuxubana kwebhedi, i-asidi ye-asidi eyomeleleyo kunye ne-resin anion resin ixutywe kunye. Oku kusebenza ngokukuko kwitanki ebhedi exubeneyo ukuba isebenze njengamawaka eiyunithi zebhedi ezixubileyo etankini. I-cation / anion exchange iphindaphindwe ebhedini yentlaka. Ngenxa yenani elikhulu lokuphindaphinda i-cation / anion exchange, ingxaki yokuvuza kwesodium isonjululwe. Ngokusebenzisa ibhedi exubeneyo, unokuvelisa awona manzi aphezulu asezantsi.
