Cov txaj txaj sib tov feem ntau yog siv hauv kev lag luam ua kom dej huv rau txheej txheem dej kom ua tiav cov dej tsis zoo (xws li tom qab rov qab osmosis system). Lub npe ntawm cov txaj sib xyaw suav nrog muaj zog acid cation txauv resin thiab muaj zog puag anion txauv resin.
Muaj nuj nqi ntawm Mixed Bed Resin
Deionization (lossis demineralization) tsuas yog txhais tau tias tshem tawm cov ions. Ions raug them nqi atoms lossis cov molecules pom hauv dej nrog cov nuj nqis tsis zoo lossis tus nqi zoo. Rau ntau daim ntawv thov uas siv dej los ua tus neeg sawv cev yaug lossis tiv thaiv, cov ions no tau txiav txim siab tsis huv thiab yuav tsum tau muab tshem tawm ntawm dej.
Kev them nyiaj zoo ions raug hu ua cations, thiab tsis zoo ions raug hu ua anions. Ion pauv cov resins pauv cov cations tsis xav tau thiab anions nrog hydrogen thiab hydroxyl los tsim cov dej ntshiab (H2O), uas tsis yog ion. Cov hauv qab no yog cov npe ntawm cov ions ntau hauv cov dej hauv nroog.
Txoj Cai Ua Haujlwm Ntawm Cov Khoom Sib Txawv Txaj
Cov txaj txaj sib xyaw tau siv los tsim cov dej deionized (demineralized lossis "Di"). Cov resins no yog cov hlaws me me ua los ntawm cov organic polymer saw nrog them nqi ua haujlwm pab pawg hauv cov hlaws. Txhua pab pawg ua haujlwm tau them tus nqi zoo lossis tsis zoo.
Cationic resins muaj cov pab pawg ua haujlwm tsis zoo, yog li lawv nyiam qhov zoo them ions. Muaj ob hom cation resins, tsis muaj zog acid cation (WAC) thiab muaj zog acid cation (SAC). Cov kua qaub cation tsis muaj zog feem ntau yog siv rau dealkalization thiab lwm yam kev siv tshwj xeeb. Yog li ntawd, peb yuav tsom mus rau lub luag haujlwm ntawm cov kua qaub cation muaj zog siv hauv kev tsim cov dej deionized.
Anionic resins muaj cov pab pawg ua haujlwm zoo thiab yog li ntawd nyiam tsis zoo them ions. Muaj ob hom anion resins; Tsis muaj zog puag anion (WBA) thiab muaj zog puag anion (SBA). Ob hom anionic resins tau siv hauv kev tsim cov dej deionized, tab sis lawv muaj cov yam ntxwv sib txawv hauv qab no:
Thaum siv hauv cov txaj sib xyaw, WBA cob tsis tuaj yeem tshem cov silica, CO2 lossis muaj peev xwm ua kom cov kua qaub tsis muaj zog, thiab muaj pH qis dua nruab nrab.
Cov txaj txaj sib xyaw tshem tawm tag nrho cov anions hauv cov lus saum toj no, suav nrog CO2, thiab muaj qhov siab dua pH nruab nrab thaum siv nyob rau hauv ob lub txaj ywj pheej vim muaj sodium tawm.
Sac thiab SBA Resins tau siv hauv txaj sib xyaw.
Txhawm rau tsim cov dej deionized, cation resin tau rov tsim dua tshiab nrog hydrochloric acid (HCl). Hydrogen (H +) raug them zoo, yog li nws txuas nws tus kheej rau qhov tsis zoo them nyiaj cationic cob hlaws. Cov anion cob tau rov tsim dua tshiab nrog NaOH. Hydroxyl pawg (OH -) raug them tsis zoo thiab txuas lawv tus kheej mus rau qhov them nyiaj zoo anionic cob hlaws.
Cov ions sib txawv tau nyiam rau cov hlaws dai nrog lub zog sib txawv. Piv txwv li, calcium nyiam cationic cob hlaws ntau dua li sodium. Cov hydrogen ntawm cov cationic cob cov hlaws thiab cov hydroxyl ntawm cov anionic cob hlaws tsis muaj zog txaus rau cov hlaws. Qhov no yog vim li cas ion pauv tau tso cai. Thaum qhov ua tau zoo cation ntws los ntawm cov cationic cob hlaws, cov cation pauv yog hydrogen (H +). Ib yam li ntawd, thaum cov anion nrog cov nqi tsis zoo ntws los ntawm cov anion cob hlaws, cov anion sib pauv nrog hydroxyl (OH -). Thaum koj sib xyaw hydrogen (H +) nrog hydroxyl (OH -), koj tsim H2O dawb huv.
Thaum kawg, txhua qhov chaw sib pauv ntawm cation thiab anion cob hlaws tau siv, thiab lub tank tsis tsim cov dej deionized lawm. Hauv qhov no, cov hlaws yas yuav tsum tau rov tsim dua los siv dua.
Vim li cas thiaj xaiv cov txaj txaj sib xyaw?
Yog li, tsawg kawg ob hom kev sib pauv ion yuav tsum tau los npaj cov dej ultrapure hauv kev kho dej. Ib qho cob yuav tshem tawm cov ions uas raug them zoo thiab lwm qhov yuav tshem tawm cov ions uas tsis zoo.
Hauv kev sib xyaw txaj, cationic resin yog ib txwm nyob hauv thawj qhov chaw. Thaum cov dej hauv nroog nkag mus rau hauv lub tank uas muaj cov cation cob, txhua qhov txiaj ntsig zoo cations raug nyiam los ntawm cation cob hlaws thiab sib pauv rau hydrogen. Cov anions nrog tus nqi tsis zoo yuav tsis nyiam thiab dhau los ntawm cov cationic cob hlaws. Piv txwv li, cia peb kuaj xyuas cov tshuaj calcium chloride hauv cov dej pub. Hauv kev daws teeb meem, calcium ions tau them nyiaj zoo thiab txuas lawv tus kheej rau cationic hlaws kom tso hydrogen ions. Chloride muaj qhov tsis zoo, yog li nws tsis txuas nws tus kheej rau cov cationic cob hlaws. Hydrogen nrog tus nqi zoo txuas nws tus kheej rau chloride ion los tsim hydrochloric acid (HCl). Cov txiaj ntsig tau los ntawm cov khoom sib pauv lub hnab yuav muaj pH qis heev thiab muaj kev coj ua ntau dua li cov dej pub nkag.
Cov dej ntws los ntawm cationic resin yog tsim los ntawm cov kua qaub thiab cov kua qaub uas tsis muaj zog. Tom qab ntawd, cov kua qaub yuav nkag mus rau hauv lub tank uas ntim nrog cov tshuaj anion. Anionic resins yuav nyiam qhov tsis zoo them nyiaj anions xws li chloride ions thiab pauv lawv rau pawg hydroxyl. Qhov tshwm sim yog hydrogen (H +) thiab hydroxyl (OH -), uas yog H2O
Qhov tseeb, vim "sodium leakage", lub txaj sib xyaw ua ke yuav tsis tsim H2O tiag. Yog tias sodium txeej dhau lub cation pauv lub tank, nws ua ke nrog hydroxyl los tsim sodium hydroxide, uas muaj qhov ua tau zoo. Sodium txau tshwm sim vim tias sodium thiab hydrogen muaj qhov zoo sib xws rau cationic cob hlaws, thiab qee zaum sodium ions tsis pauv hydrogen ions lawv tus kheej.
Hauv cov txaj sib xyaw ua ke, muaj zog acid cation thiab muaj zog puag anion resin tau sib xyaw ua ke. Qhov no ua tau zoo ua rau lub txaj txaj sib xyaw ua haujlwm raws li ntau txhiab chav sib xyaw hauv lub tank. Kev sib hloov cation / anion tau rov ua dua hauv txaj txaj. Vim muaj coob tus rov ua cation / anion ntau dua, qhov teeb meem ntawm sodium to tau daws. Los ntawm kev siv lub txaj sib xyaw, koj tuaj yeem tsim cov dej deionized zoo tshaj plaws.
