Acid Washed Activated Carbon

Cov pa roj carbon activated yog dav siv hauv tshuaj, khoom noj khoom haus, tshuaj, thiab ib puag ncig kev lag luam los adsorb impurities thiab kab mob los ntawm cov kua thiab roj. Pickling activated carbon yog kho activated carbon nrog acidic tov kom txo tau cov tshauv thiab ntab tshauv ntawm activated carbon thiab txhim kho cov adsorption efficiency ntawm activated carbon.

Kev ntxuav cov kua qaub yuav tsum kho cov pa roj carbon activated nrog cov kua qaub, feem ntau hydrochloric lossis sulfuric acid. Cov kua qaub dissolves cov oxides thiab lwm yam impurities uas tau sau nyob rau saum npoo ntawm cov pa roj carbon thaum siv, tawm hauv qab ib tug huv si thiab active nto. Cov kua qaub ntxuav kuj tshem tawm cov kab mob organic uas tuaj yeem muaj, xws li kab mob thiab kab mob.

Cov txheej txheem ntxuav cov kua qaub yog qhov yooj yim thiab tuaj yeem ua rau ntawm qhov chaw lossis hauv qhov chaw tshwj xeeb. Cov pa roj carbon activated yog thawj zaug tshem tawm ntawm cov kua dej lossis cov pa roj thiab tshuaj xyuas kom tshem tawm cov khoom loj lossis cov khib nyiab. Tom qab ntawd cov pa roj yog muab tso rau hauv lub tank lossis lub nkoj thiab npog nrog cov kua qaub. Cov tshuaj yog agitated rau ib tug predetermined lub sij hawm, feem ntau ob peb teev, los xyuas kom meej tias cov kua qaub nkag mus rau cov carbon thiab dissolves tej impurities. Tom qab ntawd cov kua qaub yog drained, thiab cov pa roj yog rinsed nrog dej kom tshem tawm cov kua qaub seem.

Cov txiaj ntsig ntawmacid ntxuav activated carbonmuaj ntau. Acid ntxuav txo cov hmoov tshauv thiab ntab tshauv ntawm cov pa roj carbon activated thiab txhim kho lub peev xwm adsorption ntawm cov pa roj carbon monoxide, ua kom nws cov txiaj ntsig thiab kev ua tau zoo. Cov txheej txheem tseem tshem tawm cov kab mob organic uas tuaj yeem tshwm sim, ua rau cov pa roj carbon zoo dua los siv hauv cov ntawv thov xws li kev kho dej haus.

Hauv kev xaus, kev ntxuav cov kua qaub yog cov txheej txheem tseem ceeb rau kev tswj xyuas qhov ua tau zoo thiab muaj txiaj ntsig ntawm cov pa roj carbon activated. Cov txheej txheem tshem tawm impurities, organic paug, thiab lwm yam khoom uas tuaj yeem degrade cov txiaj ntsig ntawm carbon. Los ntawm kev ua kom lub neej ntev ntawm cov pa roj carbon activated, kev ntxuav cov kua qaub tuaj yeem txuag nyiaj thiab muab cov kev daws teeb meem zoo dua rau adsorption hauv ntau qhov kev lag luam.
