Thaum tib neeg xav txog huab cua pom kev, lim dej tsim los mus cuab hmoov av thiab paj ntoos feem ntau tuaj rau lub siab. tusactived carbon v bank lim, Leveraging nws cov tub ntxhais "molecular {{{}} theem purificans xws li cov pa roj cua txawv (vocs), kua qaub / alkaline gases, thiab tsw qab molecules. Los ntawm ob lub tshuab ua dual me me ntawm kev tshaj tawm thiab tshuaj cov tshuaj tiv thaiv, cov ntxaij lim dej tuaj yeem siv tshuaj kom huv.
Kho tus mob lub cev: lub "molecular ntxiab" ntawm cov qauv microporous
Cov tub ntxhais ntawm adsorption dag nyob rau hauv lub synergistic nyhuv ntawm tus adsorbent cov qauv sib dhos thiab cov van der waals rog. Cov micropores no, xws li loj los ntawm 5 txog 500 nanometers, ua zoo li ntom ntxiab. Thaum cov roj av molecules tau nkag mus rau hauv kev sib cuag nrog tus adsorbent lub npoo, lawv khov kho "ntes" los ntawm van der WAsals rog.
Tag nrho cov txheej txheem tuaj yeem faib ua peb ntu tseem ceeb: thawj zaug, "sab nraud diffusion" theem uas muaj roj av uas diffuse rau sab nraud ntawm adterbent; Tom qab ntawd, "sab hauv diffusion" theem, nyob rau hauv uas lwg shuttle los ntawm cov microses mus rau sab hauv; Thiab thaum kawg, cov molecules yog adsorbed thiab tsau rau saum npoo.
Lub cev adsorption mechanism ntawm actived carbon lim muaj qhov muaj kuab paug xws li formaldehyde, tab sis nws kuj muaj kev txwv loj. Adsorption yog ntau dua ntawm cov kub tsawg, thiab tom qab muaj kev lom zem, kev xav tau tuaj yeem tshwm sim nrog kev nce kub lossis siab hloov. Tus txheej txheem no tau thim rov qab.
Tshuaj lom adstorption: "cov kuab paug churinator" ntawm hom phiaj hloov dua siab tshiab
Cov tub ntxhais ntawm tshuaj adsorption yog kev hloov kho tshuaj ntawm cov adsorbent. Los ntawm cov tswv yim xws li Ipregnation thiab grafting tshuaj reagents yog thauj mus rau cov khoom sib txawv, hloov cov kuab paug los ntawm kev ua "adsorbed" rau "hloov dua siab tshiab" rau "hloov dua siab tshiab" "
Kev hloov kho nruab nrab
Rau acidic roj, ib qho alkaline reagent xws li koh yog impregnated rau hauv cov pa roj carbon kom ua haujlwm thiab tsim cov ntsev tsis muaj mob. Rau alkaline roj, acidic lim xov xwm yog siv rau kev nruab nrab. Catalytic oxidation: Ntxiv cov catalysts xws li mno₂ decomposes toxic roj zoo li hydrogen sulfide thiab ozone rau hauv dej thiab tsis muaj mob oxides.
Tshuaj Lom Zem
Cov pab pawg ua haujlwm saum npoo uas muaj kuab paug nyob ruaj khov nrog cov kuab paug, kom immobilizing molecules thiab tiv thaiv kev pheej hmoo ntawm kev pheej hmoo ntawm desorption.
Cov txheej txheem tshuaj lom neeg kos npe hauv actived carbon v bank lim dej yog qhov ua tau zoo, thiab kev tshem tawm tau kev ua paug tau ntau zaus lossis txawm kaum lub sijhawm.
Txhim Kho Cov Khoom Lim Cov Khoom Siv Morphology
Txhawm rau hais txog qhov teeb meem ntawm kev tiv thaiv tsis txaus ntawm cov qauv kos thiab cov kuab paug ntawm cov lim dej
Honeycomb tus qauv
Tus adsorbent yog tsim rau hauv honeycomb thaiv, uas txo cov roj flow tiv taus ntawm ntau dua 30% piv rau cov ntxaij lim dej particle- Nws yog dav siv nyob rau hauv nruab nrab cov tshuab cua txias.
V - Tus Qauv Tsim
Teeb duab ntawm cov tshuab lim dej pleasing, cov carbon {} Raws li cov khoom siv lim hauv lub v {1} Nrhiav rau thaj chaw uas pom tsis pub dhau qee qhov chaw. Nws yog haum rau cov cua ntshiab tshuab hauv cov tsev lag luam.
Ntim qauv
Siv cov kev ntsuas siab siab - qhov tsis muaj peev xwm sib xyaw ntawm cov xwm txheej zoo nkauj, nws muaj qhov muaj peev xwm muaj huab cua zoo, tab sis nws muaj cua tsis zoo.
Cov Hluav Taws Xob Hluav Taws Xob ntawm Staged Pom
Txawj paub txog kev siv tshuaj siv tshuab feem ntau siv cov qauv tsim ntawm "Pre6 -} Kev Tshaj Tawm":
Ua ntej - piltration txheej
Siv ib thawj kev ua haujlwm los yog nruab nrab ua kom muaj zog los cuam tshuam rau cov teeb meem thiab cov plaub hau, tiv thaiv lawv los ntawm txhaws cov tshuaj lim dej hauv lub neej.
Tseem Ceeb Tshuaj Tshiab Adsorption Txheej
Cov lim lim lim lim dej tsim nyog yog xaiv raws li hom kuab paug. Rau cov vocs muaj, ib txheej composite ntawm actived carbon thiab tshuaj impregnation yog siv; Rau cov kua qaub thiab alkaline roj, tshwj xeeb nruab nrab lim xov xwm yog siv; Thiab rau cov kuab paug paug, ntau -}} me me} tshaj tawm cov qauv ua haujlwm.
Txiav txim siab
Hloov Sij Hawm Sij Hawm
Lub cev adsorption lim dej yuav tsum tau hloov raws li siab hloov pauv hloov (feem ntau thaum lub siab plias mus txog ob zaug thawj tus nqi); Rau cov tshuaj adsorption lim, cov kev pabcuam lub neej yuav tsum tau muab xam raws ntawm cov kuab paug kom tsis txhob muaj kev sib kis ob uas tsis dhau.
Kev Cia
Cov lim dej tsis siv cov tshuab lim dej yuav tsum muab khaws cia kom nruj kom tiv thaiv ntxov vim yog adsorption ntawm cov pa paug. Qhov no yog qhov tseeb tshwj xeeb rau Impregnated lim cov ntawv xov xwm, uas tej zaum yuav ua tsis muaj txiaj ntsig yog tias raug huab cua rau ntau tshaj ib hlis.
Pov tseg kom nyab xeeb
Lim tawm tom qab cov adsorption yuav muaj cov tshuaj tiv thaiv cov tshuaj tiv thaiv thiab yuav tsum tau ua kom nruj raws li cov kev phom sij phom sij. Tsis thwj teb pov tseg yog nruj me ntsis txwv.
