Vim li cas thiaj li tau txais cov pa roj carbon deodorize? Lub hauv paus ntsiab lus ntawm deodorization yog dab tsi?

Cov khoom siv khib nyiab deodorization yog cov khoom siv huv huv uas siv los tshem tawm cov ntxhiab tsw, cov organic thiab cov khoom tsis zoo hauv cov huab cua. Txoj kev kho cov roj pov tseg muaj xws li combustion method, combustion method, absorption method and adsorption method. Hnub no, kuv yuav coj koj mus kawm txog txoj kev adsorption. Cov adsorbent feem ntau yog activated carbon. Vim li cas thiaj li tau txais cov pa roj carbon deodorize? Dab tsi yog nws txoj cai deodorization?

Vim tias qhov chaw ntawm cov pa roj carbon activated yog nplua nuj nyob rau hauv thaj tsam loj ntawm cov qauv pore, cov qauv pore yog ib pawg tshuaj lom neeg uas muaj peev xwm adsorption muaj zog, uas kuj yog lub hauv paus ntsiab lus vim li cas cov pa roj carbon activated tuaj yeem deodorize.

Cov pa roj carbon activated feem ntau yog ua los ntawm cov thee, ntoo, roj av coke thiab lwm yam khoom siv raw. Cov hmoov tshauv tseem ceeb yog Fe2O3, Cao, K2O, K2O, P2O5, SO3, cl-. Cov hmoov tshauv hauv cov pa roj carbon activated yog ze ze rau kev ua haujlwm adsorption ntawm carbon. Yog hais tias cov tshuaj volatile hauv carbon raug tshem tawm, cov hmoov tshauv yuav nce ntxiv.

Tom qab kev kho cov roj pov tseg, qhov chaw ntawm cov pa roj carbon activated yuav muaj ntau cov volatiles, uas tuaj yeem rov qab siv tau tom qab kev kho mob. Cov txheej txheem rov tsim dua tshiab ntawm cov pa roj carbon monoxide muaj xws li kev tsim cov roj ntsha, thermal regeneration, ntub oxidation regeneration, microwave radiation regeneration, supercritical fluid regeneration thiab electrochemical regeneration.
