Chemical wanke deodorant kayan aikiKa'idar ita ce ta amfani da acid (sulfuric acid), alkali (sodium hydroxide), mai ƙarfi oxidizer (sodium hypochlorite) a matsayin wanki spraying bayani da gas a cikin kwayoyin ƙanshi ya yi gas-ruwa tuntuɓar, don haka da ƙanshi a cikin gas mataki canja wuri zuwa ruwa mataki, da kuma cire ƙanshi abubuwa ta hanyar maganin sinadarai da ƙanshi, oxidation ko wasu sinadarai.

(A) Chemical wanki deodorant kayan aiki

Ana amfani da kayan aikin wanki na sinadarai don cika hasumiyar, sinadarai mai sha daga saman hasumiyar zuwa ƙasa, gas mai fitarwa, ƙanshi tare da tuntuɓar mai sha, amsawa. Mai sha ruwa da kuma sharar da kwarara rabo (ruwa / gas rabo) yau da kullun ne 1-3L / m3, cikawa yau da kullun ne 2-5 m, da iska kwarara komai hasumiyar kwarara gudun yau da kullun ne 0.5-1 m / s. Cika shi da aiki mai kyau.

(2) Chemical absorbants

Ana amfani da sunadarai masu sha sun haɗa da waɗannan:

(1) sunadarai absorbant

Alkali sha ruwa yawanci amfani da ƙunshi 1-10% sodium hydroxide mafita, da hydrogen sulfide ne sosai, sauran abubuwa kamar methanol, methyl sulfide, methyl disulfide, mai acid da sauransu sau da yawa a cikin sharar ruwa tsaftacewa masana'antu haifar da wari abubuwa.

(2) acid mafita

Ana amfani da wanki na acid yafi amfani da ƙanshi ta hanyar gas mai alkali kamar ammonia, yawanci ana amfani da sulfuric acid (0.5-5% mafita) a matsayin wanki.

(3) Sodium hypochlorate mafita

Hypochloric acid a cikin bayani (HOCI yanayin wanzu)

NaOCI+H2O HOCI+NaOH……

A pH = 7.5, chlorine na mafita na sodium hypochlorite yana wanzu a cikin 50% HOCI da hypochlorite root ions (OCI-). A pH = 10, kawai 0.3% chlorine yana wanzu tare da HOCI, a pH = 1 ko 12, ， HOCI ya rarraba zuwa ion na primary chloride, saboda haka sarrafa darajar pH yana da mahimmanci.
