Ekwelapheni amakhompiyutha aguqukayo (ama-Vocs), ukukhethwa kwama-adsorbents kubalulekile. I-Carbon eyenziwe yasebenza, njenge-adderbent esetshenziswa kakhulu, inamathemba wohlelo lokusebenza olubanzi. Okulandelayo ukuhlaziywa okuningiliziwe kokusetshenziswa kwayo ngaphakathiUkwelashwa kwama-Vocs:
1. Izici zeKusebenze ikhabhoni
I-Carbon ecushiwe esebenza kahle kakhulu umthamo we-adsorption ngenxa yesakhiwo sayo esivulekile ne-porous, indawo ekhethekile ephezulu, nevolumu enkulu ye-pore. Imvelo yayo engeyona eye-polar ne-hydrophobic yenza kube yinhlangano enkulu yamagesi a-organic, okwenza ukuthi ikwazi kahle ama-adsorb benzene ama-adsorz, ama-aldehyde nama-ketones, ama-alcohols, ama-hydrocarbon, kanye nezinye izinto ezingenzayo.
2. Izinhlobo zekhabhoni evuliwe
I-carbon ecushiwe ingahlukaniswa ngokususelwa kwimithombo yezinto ezibonakalayo eluhlaza kanye nezicelo:
Ngomthombo wezinto ezibonakalayo eziluhlaza:
- Ikhabhoni esekelwe kumalahle:Kwenziwe kusuka kumalahle, kunondla okuphezulu kwemishini namandla aqinile we-adsorption.
- I-Shell-based Carbon:Kwenziwe kusuka kumagobolondo kakhukhunathi, amagobolondo e-walnut, njll., Ngokusatshalaliswa komfaniswano okufanayo, kufanelekile ama-addecule ama-organic arganic arganic.
- Ikhabhoni esekwe ngokhuni:Kuthathwe ngokhuni, ngosayizi omkhulu we-pore, okwenza kufanelekile ama-organic arganic compacts.
Ngokusebenza:
- I-Granur Carbon (GAC):Ilungele ukwelapha izingxube eziyinkimbinkimbi zamagesi ezi-organic, ezibandakanya ububanzi obubanzi be-pore kanye nokuguquguquka okuqinile.
- I-HoneyComb isebenze ikhabhoni:Yakhelwe amavolumu amakhulu omoya namagesi ahlanganisiwe aphansi, enikeza ukumelana kombhede ophansi futhi alungele izinhlelo zokusebenza zendawo enkulu.
- I-Carbon Fiber ecushiwe (ACF):Ilungele amakhompiyutha e-organic anengxenye eyodwa ngaphandle kwama-macromolecule, anikeza umthamo omkhulu we-adsorption, isivinini esisheshayo se-adsorption, inqumo elula, kanye nempilo yenkonzo ende.
3. Izimiso zokukhetha zekhabhoni eyenziwe yasebenza
Ukukhetha uhlobo olufanele lwe-carbon evuliwe kuncike kwizidingo ezithile zokwelashwa:
- Amagesi anesakhi esisodwa ngaphandle kwama-macromolecule:I-Carbon fiber ecushiwe ngenxa yamandla ayo aphezulu e-adsorption, ijubane le-adsorption esheshayo, i-deprorption elula, kanye nesikhathi eside sokuphila isikhathi eside.
- Ukuxutshwa okuyinkimbinkimbi kwamagesi a-organic:Kunconywa i-carbon ecushiwe e-granur, njengoba kunconywa usayizi wayo obanzi we-pore asebenzisa ama-diameter ahlukahlukene we-molecular.
- Ngemiqulu emikhulu yomoya namagesi ahlanganisiwe aphansi:I-HoneyComb isebenze i-carbon yisinqumo esihle kakhulu, njengoba kunciphisa ukumelana kombhede futhi kukhulisa indawo yokulala ye-adsorption.
4. Izibonelo zohlelo lokusebenza
- Ukwelashwa Kwezimboni Ukuphelelwa yigesi:Ikhabhoni eyenziwe yasetshenziswa kabanzi ezimbonini ezinjengamakhemikhali namakhemisi okuphatha amagesi aqukethe ama-Voc-aqukethe amagesi, kufaka phakathi i-benzene, i-toluene, kanye ne-xylene.
- Ukuhlanzwa komoya ngaphakathi:Izihlungi zekhabhoni ezicushiwe zisetshenziswa ezihlanzayo zomoya ukuze ususe ngempumelelo amagesi ayingozi anjenge-formaldehyde ne-benzene.
- Ukwelashwa kwegesi ye-Odor:Ezikhungweni zokwelashwa imfucuza kanye nezindawo zokwelashwa kwendle, ikhabhoni eyenziwe nge-accurated isetshenziselwa izidakamizwa ezingezinhle ezifana ne-hydrogen sulfide ne-ammonia.
5. Ukucatshangelwa okubalulekile
- Ukuvuselelwa kanye nokubuyiselwa:I-Carbon ecushiwe idinga ukuvulwa kabusha noma ithathelwe indawo ngemuva kokufinyelela ukugcwala kwe-adsorption ukuze iqhubeke nokusebenza kwayo.
- Izindlela zokuphepha:Lapho ubhekene nama-Vocs avuthayo futhi aqhume, izinyathelo zokuvimbela umlilo kanye nokuqhuma kwezimo zekhabhoni eyenziwe.
- Ukucatshangelwa Kwezomnotho:Ukukhethwa kwekhabhoni eyenziwe kusebenze kufanele kulinganise ukusebenza kwezokwelapha kanye nezindleko zezomnotho, ngokuya ngezinga lokuhlushwa kanye nokugeleza kwamagesi aphathwe.
I-carbon eyenziwe yasebenza inezicelo ezibanzi ekwelashweni kwama-Vocs. Ukukhetha uhlobo olufanele nokwenza kahle uhlelo lwayo kungathuthukisa kakhulu ukusebenza kahle kwamalungelo e-VoCS, kufaka isandla ekuvikelweni kwemvelo kanye nempilo yabantu.
