Activated carbon adsorption yog ib txoj hauv kev uas siv cov yam ntxwv ntawm micropores thiab mesopores ua adsorbents, ua lub luag haujlwm tseem ceeb hauv kev rho tawm kub. Raws li txoj kev no, cov kev daws teeb meem uas muaj kub ntws los ntawm cov pa roj carbon activated adsorption txaj tuaj yeem adhere thiab precipitate rau saum npoo ntawm cov pa roj carbon activated. Tom qab ntawd, tom qab ib tug series ntawm cov txheej txheem, nws yog thaum kawg refined rau hauv kub.
Xaiv thiab npaj cov activated carbon
Xaiv siab -cov pa roj carbon activated zoo nrog kev ua haujlwm ruaj khov adsorption, xws li Chengze qhov tshwj xeeb kub refining activated carbon, uas yog ua los ntawm cov txiv maj phaub plhaub cov khoom siv thiab muaj cov tuab thiab hnav- cov phab ntsa resistant, uas ua rau lub siab kub rho tawm tus nqi.
Cov pa roj carbon activated npaj tau dhau los ua qhov permeability thiab pom meej qhov kev ntsuam xyuas. Tau kawg, nws yog qhov zoo tshaj plaws los npaj cov pa roj carbon activated raws li European cov qauv rau smelting. Tsis tas li ntawd, kev ua haujlwm adsorption ntawm cov pa roj carbon activated tuaj yeem txhim kho los ntawm kev sib xyaw ntawm cov hlau catalytic additives.
Kauj Ruam 1: Tshuaj leaching
Ua ntej, nws yog ib qho tsim nyog los hloov cov ore los yog pov tseg uas muaj kub rau hauv cov tshuaj leaching uas muaj kub ions los ntawm cov txheej txheem leaching niaj hnub.
Kauj Ruam 2: Lim
Cov impurities thiab cov khoom siv tuaj yeem ua kom huv thiab sib cais los ntawm lub lim lossis lwm yam khoom siv, tsuas yog cov tshuaj kub.
Kauj Ruam 3: Adsorption
Hauv cov kauj ruam no, cov pa roj carbon activated yuav raug siv los nqus cov ions kub los ntawm cov dej xau. Nws yog qhov tseeb vim tias cov pa roj carbon activated muaj cov microporous thiab mesoporous cov khoom uas kub tuaj yeem tsim cov tshuaj lom neeg ruaj khov rau ntawm nws qhov chaw.
Kauj ruam 4: Detachment
Desorption yog cov kauj ruam ntawm kev sib cais kub ntawm qhov chaw ntawm cov pa roj carbon activated. Hauv cov kauj ruam no, cov pa roj carbon activated yuav raug ntxuav kom tshem tawm cov adsorbed impurities thiab carbon. Kub tuaj yeem desorbed los ntawm cua sov, dissolving, los yog tshuab plua plav. Qhov no yuav tsim sediment uas muaj kub.
Kauj Ruam 5: Roasting thiab Electrolysis
Cov kauj ruam kawg yog rho cov kub los ntawm cov sediment. Roasting tuaj yeem hloov cov sediment rau hauv cov khoom siv, uas yooj yim rau kev ua tom qab. Electrolysis, ntawm qhov tod tes, siv cov hmoov ua kom zoo zoo los lim impurities los ntawm cov txheej txheem ntawm electrolytic polishing.
Cov kauj ruam saum toj no thiab cov txheej txheem tuaj yeem ua tiav manually lossis ua tiav los ntawm qhov kev xav ntawm niaj hnub chemistry lossis txheej txheem automation los txhim kho kev tsim khoom thiab tswj cov txheej txheem - qhov no yog qhov txuas tseem ceeb heev.
