Hoʻokomo ʻia ka resin wai moʻo wai super super o ka gel gel e like me ka resin acid cation exchange resin a me ka resin exchange anion alkali ikaika, a ua hana hou ʻia a mākaukau hoʻi e kāwili ʻia.
Hoʻohana nui ʻia ia i ka hoʻomaʻemaʻe pololei o ka wai, ka hoʻomākaukau ʻana o ka wai maʻemaʻe no ka ʻoihana uila, a me ka moena hoʻowalewale e hoʻopili ʻia me nā kaʻina hana lāʻau ʻē aʻe. He kūpono ia no nā ʻano hana hoʻomaʻemaʻe wai me nā koina effluent kiʻekiʻe a me ka ʻole o nā kūlana regeneration kiʻekiʻe, e like me nā pono hōʻike, calculator hard disk, CD-ROM, board circuit circuit, nā pono uila uila a me nā huahana uila uila kikoʻī, nā lāʻau lapaʻau a me nā lāʻau lapaʻau. ʻoihana mea hoʻonani, ʻoihana mīkini pono, a pēlā aku
Hoʻohana o nā kuhikuhi kuhikuhi

Hoʻohana nui ʻia ka resin moe moe i ka ʻoihana hoʻomaʻemaʻe wai no ka polishing ʻana i ka wai e loaʻa ai ka maikaʻi o ka wai demineralization (e like me ma hope o ka ʻōnaehana osmosis hope). ʻO ka inoa o ka moena hui pū me ka resin exchange cation acid ikaika a me ka resin exchange anion base ikaika.
Hana o ka Resin Bed Mixed
Deionization (a i ʻole demineralization) ke ʻano o ka hemo ʻana o nā ion. Hoʻopiʻi ʻia nā ʻona i nā ʻoma a i ʻole nā mole i loaʻa i ka wai me nā koina ʻino a maikaʻi ʻole paha. No nā noi he nui e hoʻohana i ka wai ma ke ʻano he holoi holoi a i ʻole mea hana, manaʻo ʻia kēia mau ʻona he impurities a pono e hemo mai ka wai.
Kapa ʻia nā ion i hoʻoili ʻia ma ke ʻano he cations, a kapa ʻia nā ion i hoʻopiʻi maikaʻi ʻole ʻia he aniona. Hoʻololi nā pānaʻi ion i nā cation i makemake ʻole ʻia a me nā aniona me ka hydrogen a me ka hydroxyl e hana i ka wai maʻemaʻe (H2O), ʻaʻole ia he ion. ʻO ka papa inoa o nā iona maʻamau i ka wai kaona.
Ka Manaʻo Hana o ka Resin Bed Mixed
Hoʻohana ʻia nā resins moena huikau e hana i ka wai deionized (demineralized a i ʻole "Di") wai. ʻO kēia mau kēpau he mau ʻili lula liʻiliʻi i haku ʻia me nā kaulahao polymer organik me nā hui i hoʻopiʻi ʻia i hoʻokomo ʻia i nā pā. Loaʻa i kēlā me kēia hui hana i ka uku maikaʻi a maikaʻi ʻole paha.
He mau pūʻulu hana maikaʻi ʻole nā Cationic resins, no laila ke ʻumeʻume nei lākou i nā ioni maikaʻi. ʻElua ʻano resins cation, cation acid cation (WAC) a me cation acid ikaika (SAC). Hoʻohana nui ʻia ka resin acid cation no ka dealkalization a me nā noi ʻokoʻa ʻē aʻe. No laila, e nānā mākou i ka hana o ka resin acid cation ikaika i hoʻohana ʻia i ka hana ʻana o ka wai deionized.
He mau pūʻulu hana maikaʻi ko nā resion Anionic a no laila e ʻumeʻume i nā ion i uku maikaʻi ʻole ʻia. ʻElua ʻano resin anion; Anion kumu nāwaliwali (WBA) a me anion kumu ikaika (SBA). Hoʻohana ʻia nā ʻano resin anionic ʻelua i ka hana ʻana o ka wai deionized, akā loaʻa iā lākou nā ʻano like ʻole:
Ke hoʻohana ʻia i ka ʻōnaehana moena huikau, ʻaʻole hiki i ka resin WBA ke hemo i ka silica, CO2 a i ʻole hiki iā ia ke pale i nā waikawa nāwaliwali, a he haʻahaʻa ka pH ma mua o ka kūlike ʻole.
Lawe ka resin moe hui i nā anion āpau i ka papa i luna, me CO2, a ʻoi aku ke kiʻekiʻe ma mua o ka pH kū ʻole ke hoʻohana ʻia i kahi ʻōnaehana moe kūʻokoʻa ʻelua ma muli o ka liu ʻana o ka sodium.
Hoʻohana ʻia nā resine Sac a me SBA i ka moena huikau.
I mea e hoʻohua ai ka wai deionized, ola ka cation resin me ka waikawa hydrochloric (HCl). Hoʻoikaika maikaʻi ʻia ka Hydrogen (H +), no laila hoʻopili ia iā ia iho i nā lei kēpau cationic i hoʻopiʻi maikaʻi ʻole ʻia. Ua hoʻohou hou ʻia ka resion anion me NaOH. Hoʻopiʻi maikaʻi ʻole ʻia nā hui Hydroxyl (OH -) a hoʻopili iā lākou iho i nā lei kēpau anionic resin maikaʻi.
ʻUmeʻume ʻia nā ion ʻokoʻa i nā kēpau resin me ka ikaika ʻokoʻa. ʻO kahi laʻana, ʻumeʻume ka calcium i nā lei kēpau cationic ma mua o ka sodium. ʻO ka hydrogen ma nā lei kēpau cationic a me ka hydroxyl ma nā lei kēpau anionic ʻaʻohe mea hoihoi i nā lei. ʻO kēia ke kumu e ʻae ʻia ai ka hoʻololi ion. Ke kahe ka cation i hoʻopiʻi maikaʻi ʻia ma o nā lei kēpau cationic, he hydrogen (H +) ke kālepa cation. Pēlā nō, ke kahe ka anion me ka uku maikaʻi ʻole ma o nā lei kēpau anion, ua hoʻololi ke anion me ka hydroxyl (OH -). Ke hoʻohui ʻoe i ka hydrogen (H +) me ka hydroxyl (OH -), hana ʻoe i H2O maʻemaʻe.
ʻO ka hope loa, hoʻohana ʻia nā pūnaewele hoʻololi a pau ma nā cation a me nā lei resion anion, a ʻaʻole hana hou ka pahu wai i ka wai deionized. I kēia manawa, pono e ola hou nā lei kēpau no ka hoʻohana hou ʻana.
No ke aha e koho ai i ka resin moena huikau?
No laila, ʻelua mau ʻano o nā kēpau pānaʻi ion e pono ai e hoʻomākaukau i ka wai ultrapure i ka mālama ʻana i ka wai. E hoʻoneʻe kekahi kēpau i nā ion i hoʻopiʻi ʻia a ʻo kekahi e wehe i nā ion i hoʻopiʻi maikaʻi ʻole ʻia.
I ka ʻōnaehana moena huikau, noho mau ke kēpau cationic i ka manawa mua. Ke komo ka wai kaona i loko o ka pahu i hoʻopiha ʻia me ke kēpau cation, hoʻopili ʻia nā cations i hoʻopiʻi maikaʻi ʻia e nā copa resin beads a ua kūʻai ʻia no hydrogen. ʻAʻole e hoʻopili ʻia nā aniona me ka uku maikaʻi ʻole a hele i loko o nā lei kēpau cationic. ʻO kahi laʻana, e nānā i ka calcium chloride i ka wai hānai. I ka hopena, hoʻopiʻi maikaʻi ʻia nā ion kalipona a hoʻopili iā lākou iho i nā lei cationic e hoʻokuʻu i nā ion hydrogen. He uku maikaʻi ʻole kā Chloride, no laila ʻaʻole ia e hoʻopili iā ia iho i nā lei kēpau cationic. Hoʻopili ka hydrogen me ka uku maikaʻi iā ia iho i ka ion kloride e hana i ka waikona hydrochloric (HCl). ʻO ka hopena i loaʻa mai ka sac exchanger e loaʻa i kahi pH haʻahaʻa loa a me kahi ʻano ʻoi aku ke kiʻekiʻe ma mua o ka wai hānai e komo mai ana.
Hoʻokomo ʻia ka effluent o ke kēpau cationic i ka waikawa ikaika a me ka waikawa nāwaliwali. A laila, e komo ka wai ʻakika i loko o ka pahu i hoʻopiha ʻia me ke kēpau anion. E hoʻoulu nā anionic resins i nā anion i uku maikaʻi ʻole ʻia e like me nā iona chloride a hoʻololi iā lākou no nā hui hydroxyl. ʻO ka hopena he hydrogen (H +) a me hydroxyl (OH -), a ʻo H2O ke ʻano
I ka ʻoiaʻiʻo, ma muli o ka "sodium leakage", ʻaʻole e hoʻohua ka ʻōnaehana moena huikau i ka H2O maoli. Inā kulu ka sodium ma o ka pahu kūʻai cation, hoʻohui ʻia me ka hydroxyl e hana i ka sodium hydroxide, kahi kiʻekiʻe o ka conductivity. Hana ʻia ka liʻoma ʻo Sodium ma muli o ke ʻano like o ka sodium a me ka hydrogen i nā lei kēpau cationic, a i kekahi manawa ʻaʻole e kūleʻa nā ionona sodium iā lākou iho i nā hydrogen ion.
I loko o ka ʻōnaehana hoʻohuihui, hui pū ʻia ka cation acid a me ka resin anion base ikaika. Hiki i kēia ke hoʻohana pono i ka pahu moe i hui pū ʻia e hana ma ke ʻano he mau kaukani moena hui i loko o kahi pahu. Ua hana hou ʻia ka cation / anion i kahi moe resin. Ma muli o kahi helu nui o ka hoʻololi hou ʻana o ka cation / anion, ua hoʻonā ʻia ka pilikia o ka liu sodium. Ma ka hoʻohana ʻana i kahi moena hui, hiki iā ʻoe ke hana i ka wai deionized kiʻekiʻe loa.
