Utsi wambiri wa asphalt womwazika wokhala ndi 5-7mg/m~3 umapangidwa panthawi yopanga msonkhano wa kaboni wa chomera cha alumina.Ngati itatulutsidwa mwachindunji, idzakhudza kwambiri malo ozungulira komanso ogwira ntchito kufakitale.Poyang'ana pa fume iyi, tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono timagwiritsidwa ntchito kuyamwa ndi kuyeretsa, ndipo coke yodzaza ndi calcined imapangidwanso ndi njira yosinthira kutentha.

Choyamba, ma adsorption a calcined coke adawerengedwa, ndipo zotsatira za kutentha kwa adsorption, phula la fume, kuthamanga kwa mlengalenga ndi kukula kwa tinthu ta calcined coke pa zotsatira za adsorption za calcined coke zinawunikidwa.Zotsatira za kafukufuku zikuwonetsa kuti kuchuluka kwa fungo la phula lomwe limatulutsidwa ndi coke calcined kumawonjezeka ndi kuchuluka kwa fungo la fume la phula.Kuthamanga kwa malo otsika, kutentha pang'ono, ndi kukula kwa tinthu tating'onoting'ono zonse ndizopindulitsa pa kutsekemera kwa fume phula ndi calcined coke.The adsorption thermodynamics ya calcined coke idaphunziridwa, zomwe zidawonetsa kuti njira yotsatsira inali kutsatsa kwakuthupi.Kubwereranso kwa adsorption isotherm kukuwonetsa kuti njira yotsatsira imagwirizana ndi equation ya Langmuir.

Kachiwiri, Kutentha kusinthika ndi condensation kuchira ano zimalimbikitsa calcined coke.Zotsatira za kuchuluka kwa gasi wonyamula, kutentha kwa kutentha, kuchuluka kwa calcined coke ndi nthawi zosinthika pakukonzanso bwino kwa coke ya calcined zidafufuzidwa motsatana.Zotsatira zoyesera zikuwonetsa kuti pamene mpweya wonyamula mpweya ukuwonjezeka, kutentha kwa kutentha kumawonjezeka, ndipo kuchuluka kwa coke pambuyo podzaza calcining kumachepa, kumakhala kopindulitsa pakusintha kwachangu.Condensate ndi kuyamwa kubadwanso mchira mpweya, ndi mlingo kuchira ndi pamwamba 97%, zomwe zikusonyeza kuti condensation ndi mayamwidwe njira akhoza kuchira phula mu kusinthika mchira mpweya bwino.

Pomaliza, njira zitatu zosonkhanitsira gasi, kuyeretsa ndi kukonzanso zidapangidwa, ndipo zotsatira zake zimayikidwa.Zotsatira za ntchito zamafakitale zikuwonetsa kuti kuyeretsedwa kwa fume la asphalt ndi benzo (a) pyrene kumafika 85.2% ndi 88.64%, motsatana, pamene choyeretsacho chimagwiritsidwa ntchito kugwira ndi kuyeretsa utsi wa phula womwazika komanso wosakonzedwa.Kuchuluka kwa utsi wa asphalt ndi benzo (a) pyrene potulutsira oyeretsa kunali 1.4mg/m~3 ndi 0.0188μg/m~3, ndipo mpweya wake unali 0.04kg/h ndi 0.57×10~(-6)kg. /h, motero.Zafika pamlingo wachiwiri wa kutulutsa kwathunthu kwa zoipitsa mpweya GB16297-1996.
