Ubuchwepheshe bokuvutha be-Catalytic njengenye yezinqubo zokwelashwa kwegesi yemfucuza ye-VOC, ngenxa yezinga layo eliphezulu lokuhlanza, izinga lokushisa eliphansi lokuvutha (<350 ° C), ukusha ngaphandle komlilo ovulekile, ngeke kube khona ukungcola kwesibili njengesizukulwane se-NOx, ukuphepha, ukonga amandla nokuvikelwa kwemvelo nezinye izici, kuhlelo lokusebenza lwemakethe yokuvikela imvelo lunamathemba amahle okuthuthukiswa.Njengesixhumanisi esibalulekile sobuchwepheshe sohlelo lokuvutha kwe-catalytic, ubuchwepheshe be-catalyst synthesis nemithetho yohlelo lokusebenza kubaluleke kakhulu.
1. Isimiso sokusabela komlilo we-catalytic
Umgomo we-catalytic combustion reaction ukuthi i-organic waste gas i-oxidized ngokuphelele futhi ibola ngaphansi kwesenzo se-catalyst ekushiseni okuphansi ukuze kuzuzwe inhloso yokuhlanza igesi.Ukushiswa kwe-Catalytic kuwukusabela okujwayelekile kwesigaba segesi esiqinile, futhi umgomo wako wukuthi izinhlobo zele-oksijini ezisebenzayo zibamba iqhaza ekufakweni kwe-oxidation ejulile.
Enqubweni yokuvutha kwe-catalytic, umsebenzi we-catalyst ukunciphisa amandla okwenza kusebenze okusabela, kuyilapho ama-molecule asabelayo anothiswa endaweni ye-catalyst ukuze kwandiswe izinga lokusabela.Ngosizo lwe-catalyst, i-organic waste gas ingashisa ingabi nalangabi ekushiseni okuphansi futhi ikhulule inani elikhulu lokushisa ngenkathi i-oxidizing futhi ibola ibe yi-CO2 ne-H2O.
3. Iqhaza kanye nomthelela we-VOCs catalyst kusistimu yokuvutha kwe-catalytic
Imvamisa, izinga lokushisa lokuzishisa lama-VOC liphezulu, futhi amandla okuvula ama-VOCs angancishiswa ngokusebenza kwe-catalyst, ukuze kuncishiswe izinga lokushisa lomlilo, kuncishiswe ukusetshenziswa kwamandla nokonga izindleko.
Ngaphezu kwalokho, izinga lokushisa lomlilo we-general (ayikho i-catalyst ekhona) izoba ngaphezu kuka-600 ° C, futhi ukushisa okunjalo kuzokhiqiza ama-nitrogen oxides, okuvame ukubizwa ngokuthi i-NOx, okubuye kube ukungcola okufanele kulawulwe ngokuqinile.Ukushiswa kwe-Catalytic ukuvutha ngaphandle kwelangabi elivulekile, ngokuvamile ngaphansi kuka-350 ° C, ngeke kube khona isizukulwane se-NOx, ngakho-ke kuphephile futhi kunobungani bemvelo.
4. Yini isivinini somoya?Yiziphi izici ezithinta isivinini somoya
Kuhlelo lwe-VOCs catalytic combustion, isivinini sesikhala sokusabela ngokuvamile sisho isivinini sesikhala sevolumu (GHSV), ekhombisa umthamo wokucubungula we-catalyst: isivinini sesikhala sokusabela sisho inani legesi elicutshungulwa ngesikhathi seyunithi ngayinye umthamo weyunithi ye-catalyst. ngaphansi kwezimo ezithile, iyunithi ingu-m³/(m³ catalyst •h), engenziwa lula njengokuthi h-1.Isibonelo, umkhiqizo umakwe ngesivinini sesikhala esingu-30000h-1: kusho ukuthi i-cubic catalyst ngayinye ingakwazi ukuphatha i-exhaust gesi engu-30000m³ ngehora.Isivinini somoya sibonisa amandla okucubungula ama-VOC we-catalyst, ngakho-ke ihlobene eduze nokusebenza kwe-catalyst.
5. Ubudlelwano phakathi komthwalo wensimbi eyigugu kanye nesivinini somoya, ingabe ukuphakama kwensimbi eyigugu kuba ngcono?
Ukusebenza kwe-catalyst yensimbi eyigugu kuhlobene nokuqukethwe kwensimbi eyigugu, usayizi wezinhlayiya nokuhlakazeka.Ngokufanelekile, insimbi eyigugu ihlakazeke kakhulu, futhi insimbi eyigugu ikhona kumthwali ezinhlayiya ezincane kakhulu (ama-nanometer amaningana) ngalesi sikhathi, futhi insimbi eyigugu isetshenziswa ngezinga elikhulu kakhulu, futhi amandla okucubungula we-catalyst alungile. kuhlotshaniswa nokuqukethwe kwensimbi eyigugu.Kodwa-ke, lapho okuqukethwe kwezinsimbi eziyigugu kuphakeme ngezinga elithile, izinhlayiya zensimbi kulula ukuqoqa futhi zikhule zibe izinhlayiya ezinkulu, indawo yokuthintana yensimbi eyigugu nama-VOC iyancipha, futhi iningi lezinsimbi eziyigugu zigoqwe ngaphakathi, ngalesi sikhathi, ukwandisa okuqukethwe kwezinsimbi eziyigugu akusizi ekwenzeni ngcono umsebenzi we-catalyst.
