Kunyango lweendawo ezisebenza eziguqukayo (VOCs), ukukhetha ii-addonvents kubalulekile. Ikhabhoni evulekileyo, njenge-adsorblenment esetyenziswayo esetyenziswayo, inamathuba okusebenza okubanzi. Oku kulandelayo luhlalutyo olucacileyo lokusebenzisa kwayoUnyango lweVoCS:

1. Iimpawu zeI-carbon esebenzayo

I-carbon esebenzayo ibonisa umthamo we-adsor ogqwesileyo ngenxa yesakhiwo sayo esikhululekileyo nesizinzileyo, indawo ephezulu yomhlaba, kunye nevolumu yePoyini enkulu. Indalo yayo engeyiyo i-hydrophobic yenza ukuba ibubumbelelene kakhulu kwiigesi ze-organic, iyenza ukuba ivule i-adfenb i-adfenes, i-AldeHYS kunye neKedrocarbons, kunye nezinye iiVoCs, kunye nezinto ezinjalo.

I-2. Iindidi zekhabhoni esebenzayo

Ikharbon evulekileyo inokuhlelwa ngokusekwe kwimithombo yezinto ezibonakalayo kunye nokusetyenziswa:

Ngomthombo wezinto eziMfusa:

• Ikhabhoni esekwe kwi-Coal:Yenziwe kumalahle, inamandla amakhulu okusebenza kunye ne-adsortion yokufumana amandla.
• Ikhabhoni esekwe kwi-Shell:Yenziwe kwiigobolondo ze-coconut, iigobolondo ze-walnut, njl. Njl.
• Ikhabhoni esekwe ngamaplanga:Ithathwe kwiinkuni, kunye nesayizi enkulu ye-pore, iyenza ifanelekile ukuba i-adfen i-add ivume i-macromoralecular comples.

Ngesicelo:

• I-carbon esebenzayo (i-GAC):Ilungele ukunyanga umxube onzima wegesi ye-organic, ebonisa ubungakanani bobukhulu obubanzi be-porere kunye nokuzimela okuqinileyo.
• Incindi ye-Carbon isebenze i-carbon:Yenzelwe imitha enkulu yomoya kunye neegesi ezixineneyo ezixineneyo, zibonelela ngokuchasene nokulala phantsi kwaye zilungele ukusetyenziswa kwendawo enkulu.
• I-carbon ye-carbon esebenzayo (i-ACF):Eyona nto ifanelekileyo yezinto eziluncedo zecandelo elinye ngaphandle kwe-macromolecules, ukubonelela ngomthamo we-adsorction, isantya se-adsorption, umdaniso olulula, kunye nobomi benkonzo ende.

I-3. Imigaqo yokukhetha i-carbon esebenzayo

Ukukhetha uhlobo olufanelekileyo lwekhabhoni esebenzayo kuxhomekeke kwiimfuno zonyango ezithile:

• I-Gases-Point-Points ngaphandle kweMacromolecules:I-carbon ye-carbon esebenzayo ikhetha ngenxa yesakhono esiphezulu se-adsortion, isantya se-adsorption, umdaniso olulula, kunye ne-Liespan ende.
• Ngomxube ontsonkothileyo wegesi ye-organic:Ikhabhoni esebenzayo ye-Granular iyacetyiswa, njengoko ububanzi bayo be-poreous ye-poreed befumana i-seineter ye-winetic ye-winetic.
• Imitha enkulu yomoya kunye neegesi ezixineneyo ezixineneyo:I-Bunycomb yenze i-carbon esebenzayo yeyona nto iphambili, njengoko inciphisa ukumelana nokulala nokwandisa indawo yokulala ye-adsorption.

4. Imizekelo yesicelo

• Unyango lwegesi yokuphelisa igesi:Ikharbon esebenzayo isetyenziswa ngokubanzi kumashishini anje ngeekhemikhali kunye namayeza okunyanga i-VOC eneegesi, kuquka ne-bedlene, i-tolene, kunye neXyyne.
• Ukucocwa komoyaIifilitha zekharbon esebenzayo zisetyenziswa kwiinqwelwana zomoya ukuba zisuse ngokufanelekileyo iigesi eziyingozi ezinjengeFomaldehydes kunye ne-Benzene.
• Unyango lwegesi ye-Odor:Kwizityalo zonyango lwenkunkuma kunye neendawo zokunyanga zonyango, i-carbon esebenzayo isetyenziselwa ukuvuma izinto ezinamandla anjenge-hydrogen sulfide ne-ammonia.

5. Ukuqwalaselwa okuphambili

• Ukuhlaziywa kwakhona kunye nokutshintshwa:I-carbon esebenzayo kufuneka iphinde iphinde iphinde iphinde iphinde iphinde ifike kwakhona ukugcwaliswa kwe-adlonger ukugcina ukusebenza kwayo.
• Amanyathelo okhuseleko:Xa ujongene nee-VOC ezinokutsha kunye nokuqhushumba, amanyathelo omlilo kunye nokuqhuma kwe-shopsion yekharbhoni esebenzayo kufuneka ziqwalaselwe.
• Ukuqwalaselwa kwezoqoqosho:Ukukhetha i-carbon esebenzayo kufuneka kulungelelanise ukusebenza ngempumelelo kunye neendleko zoqoqosho, kuxhomekeka kwiqondo loxilolo kunye nenqanaba lokuhamba kweegesi eziphathwayo.

Ikharbon esebenzayo inezicelo ezibanzi kunyango lweVOCS. Ukukhetha uhlobo olufanelekileyo kunye nokuphucula isicelo kwalo kunokuphucula kakhulu ukusebenza kwe-VOCS, ekwenzeni ukhuseleko lwendalo esingqongileyo kunye nempilo yabantu.
