Isikimu sokulethwa kwekhabhoni esicushiwe
Izinto ezibonakalayo
I-Actiated carbon ikhabhoni ephathwe ngokukhethekile eshisisa izinto ezingavuthiwe (amagobolondo amantongomane, amalahle, izinkuni, njll.) lapho kungekho moya ukuze kuncishiswe izingxenye ezingezona ikhabhoni (le nqubo ibizwa nge-carbonization), bese isabela negesi, futhi ubuso bumbozwe umoya.Ukuguguleka, okuholela ekwakhiweni kwe-microporous (le nqubo ibizwa ngokuthi i-activation).Njengoba inqubo yokwenza kusebenze iyinqubo encane kakhulu, okungukuthi, ukuguguleka komhlaba kwenani elikhulu lama-molecule e-carbide kuwukuguguleka kwamaphuzu, ngakho indawo yekhabhoni ecushiwe inezimbotshana eziningi ezincane.Iningi lamadiameter e-micropore ebusweni bekhabhoni ecushiwe aphakathi kuka-2 no-50 nm.Ngisho nenani elincane lekhabhoni ecushiwe linendawo enkulu.Indawo engaphezulu yegramu ngayinye yekhabhoni ecushiwe ingama-500 kuya ku-1500 m2.Cishe zonke izinhlelo zokusebenza zekhabhoni ecushiwe zisekelwe kulesi sici sekhabhoni ecushiwe.
Izinkinga zokukhiqiza
1. Ukwelashwa ngekhabhoni esebenzayo kuyinqubo yokwelapha ethuthukisiwe, evame ukucatshangelwa kuphela lapho izinkomba zekhwalithi yamanzi zamanzi angcolile zingasakwazi ukuhlangabezana nezidingo zokuchithwa kwamanzi angcolile ngezinye izinqubo ezivamile.
2. Ngaphambi kokunquma ukukhetha inqubo yekhabhoni ecushiwe, amanzi angcolile enqubo yokwelapha yangaphambilini noma amasampula amanzi anekhwalithi efanayo yamanzi kufanele asetshenziselwe ukuhlolwa kwekholomu yekhabhoni, kanye nekhabhoni ecushiwe yemikhiqizo ehlukene kanye nokucaciswa kufanele kuhlolwe, bese imingcele yokuklama eyinhloko, njengokuhlunga kwamanzi, kufanele itholakale ngokuhlolwa.isivinini, ikhwalithi yamanzi angcolile, umjikelezo wokugcwala kwamanzi, umjikelezo omfushane wokuwashwa ngemuva, njll.
3. Amanzi anethonya lenqubo yekhabhoni ecushiwe kufanele ahlungwe kuqala ukuze kuvinjelwe ungqimba lwekhabhoni ukuthi lungavinjelwa ngenxa yenani elikhulu lokuqinile okumisiwe.Ngesikhathi esifanayo, ukugxila kwezinto eziphilayo emanzini anamandla akufanele kube phezulu kakhulu ukuze kugwenywe ukugcwala ngokweqile kwekhabhoni ecushiwe, ukuze kuqinisekiswe umjikelezo wokuvuselela onengqondo kanye nezindleko zokusebenza.Uma ukugxiliswa kwe-CODc kwamanzi anethonya kungaphezu kuka-50-80 mg/L, inqubo yebhayoloji yekhabhoni ecushiwe kufanele ngokuvamile icatshangelwe ukwelashwa.
4. Ukuze kubuyiselwe ukuhlanzwa kwamanzi noma ezinye izinqubo zokuhlanza lapho ukuhlangana kokungcola okweqa izinga kuvamise ukushintsha, iyunithi yokwelapha ikhabhoni ecushiwe kufanele ifakwe ipayipi elinwetshiwe noma elidlulayo.Iyunithi yekhabhoni ecushiwe, engasindisa umthamo we-adsorption wombhede wekhabhoni ocushiwe futhi yandise ngempumelelo umjikelezo wokukhiqiza kabusha noma wokushintsha.
5. Uma usebenzisa umbhede ongashintshi, cabanga ukudizayina ichibi lokubhukuda eliyisipele noma umbhoshongo wekhabhoni ngokuya ngokukhiqizwa kabusha noma umjikelezo wokushintshwa kwekhabhoni ecushiwe.Imibhede engomahamba-nendlwana kufanele icatshangelwe ukuze kwenziwe ikhophi yasenqolobaneni uma kunesidingo.
6. Njengoba ukuthintana phakathi kwekhabhoni ecushiwe kanye nensimbi evamile kuzodala ukugqwala okukhulu kwe-electrochemical, isakhiwo sikakhonkolo esiqinisiwe noma insimbi engagqwali, ipulasitiki nezinye izinto kufanele kucatshangelwe kuqala lapho kuklanywa idivayisi yokwelapha ikhabhoni ecushiwe.Uma kusetshenziswa i-carbon steel evamile, indawo engaphakathi yedivayisi kufanele ifakwe i-epoxy resin, futhi ubukhulu be-lining kufanele bube bukhulu kuno-1.5mm.
7. Uma usebenzisa impushana ecushwe ikhabhoni, cabanga ngokuvikela umlilo nokuqhuma, nezinto zikagesi ezisetshenziswayo nazo ziyahlangabezana nezidingo zokuvikela ukuqhuma.
Sebenzisa okokusebenza
I-vacuum feeder (ngoba impushana yekhabhoni ecushiwe ilungile, okubalulekile kanye nokucoleka kwesici sokuhlunga kudingeka kucatshangelwe).
