2.Tsarin zaɓin hanya
Akwai hanyoyin tsarkakewa da yawa don malodorous gas, galibi gami da masu zuwa:
1)Hanyar rufe fuska (hanyar tsaka-tsaki, hanyar kawar da wari): Ana gaurayawan iskar gas mai ƙamshi a cikin cakuda mai ƙamshi don rufe warin.
2)Hanyar iskar iska (konewa): Yi amfani da mafi yawan abubuwa masu wari tare da rage halaye, irin su sulfur Organic da amines, don aiwatar da deodorization na oxidative. Akwai thermal oxidation da catalytic konewa.
3)Hanyar fesa ruwa: Narkar da iskar gas da ruwa don cire wari mara kyau.
4)Hanyar shayar da iskar shaka sinadarai: Aron ka'idar aikin naúrar sinadarai, ya dace da zalunta iskar gas tare da babban taro na gurɓataccen gurɓataccen iska, tare da balagaggen fasaha, aikin barga da ƙananan sawun ƙafa, ingantaccen aiki ya fi girma.
5)Hanyar adsorption: Abubuwan wari suna tallata su ta hanyar adsorbent mai kunna carbon, yumbu mai kunnawa, da dai sauransu, tare da ingantaccen deodorization da ƙarancin amfani.
6)Photocatalytic oxidation Hanyar: A ƙarƙashin iska mai ƙarfi na hasken ultraviolet mai ƙarfi, halayen daban-daban (halayen hoto na hoto) irin su buɗe zobe da karya haɗin haɗin sinadarai na mahaɗan maras tabbas (VOCs) sun lalace cikin ƙananan ƙwayoyin ƙwayoyin cuta kamar CO2 da H2O; a gefe guda, ana amfani da hasken ultraviolet mai ƙarfi. Oxygen a cikin iska yana haskakawa ta hanyar haske don samar da ozone, ozone yana shayar da hasken ultraviolet don samar da oxygen free radicals da oxygen, kuma oxygen free radicals amsa tare da ruwa tururi a cikin iska don samar da hydroxyl free radicals, mai karfi oxidant, da Organic The shaye gas. gaba daya oxidized zuwa inorganic abubuwa kamar ruwa da carbon dioxide. Bugu da kari, ozone da ba ya sha ultraviolet haskoki shi ma yana da karfi da iskar oxygen, kuma bayan tuntuɓar da wasu sharar gida, yana yin oxidize don samar da abubuwa marasa ƙarfi kamar ruwa da carbon dioxide.
7)Hanyar da aka haɗa: Lokacin da buƙatun deodorization ya yi girma kuma yana da wuya a cika buƙatun tare da tsari guda ɗaya na tsarkakewa, ana amfani da hanyar haɗin kai, wato, ana amfani da hanyoyi da yawa a hade don inganta ingantaccen aikin deodorization da rage farashin aiki.
Zaɓan tsarin deodorization na photocatalytic. Ana fitar da iskar gas ɗin abincin kifi ta cikin daftarin da aka jawo, kuma ya shiga cikin kawar da kura,sanyaya da dehumidification kayan aikita hanyar bututun murfin ƙura don pretreatment, sannan ya shiga cikinphotocatalytic deodorization kayan aiki.Bayan jiyya, yana iya kaiwa ga fitarwa mai inganci.
Bayan fesa ruwa mai yawa na sanyaya, yawancin tururi mai zafi da aka shirya daga kayan aikin Fanxiang ana tashe kuma a aika zuwa ga hasumiyar deodorization, da kuma gauraye kura a tururi shima ana wanke shi. Daga nan sai a tura shi zuwa tacewa mai cire humidification don bushewa a ƙarƙashin tsotsar abin busa. A ƙarshe, ana karkatar da tururi zuwa waniion photocatalytic purifier, Inda ake amfani da bututun haske na ion da UV don wargaza kwayoyin wari, wanda ke kawo tururi har zuwa ka'idojin fitarwa.
