Hasumiyar fure

Hasumiyar fure (ko ginshiƙi na furewa ko ɗakin furewa) mai amfani da iskar gas ne wanda aka yi amfani da shi don cimma taro da canja wurin zafi tsakanin ci gaba da iskar iskar gas (wanda zai iya ƙunsar ƙwayoyin da aka warwatse) da kuma warwatsa ruwa. Ya ƙunshi jirgi mara amfani wanda aka yi da ƙarfe ko filastik, da kuma nozzles wanda ke yayyafa ruwa a cikin jirgi. Ruwan iskar gas yawanci yana shiga a kasan hasumiyar kuma yana motsawa sama, yayin da ake yayyafa ruwa ƙasa daga matakin ɗaya ko fiye. Wannan kwararar iskar gas da ruwa a bangarori daban-daban ana kiranta kwararar kwararar.

 Bayani na gaba ɗaya 
Ana iya amfani da wannan nau'in fasaha misali a matsayin mai tsabtace ruwa don kula da gurɓataccen iska. Gudun da ke faruwa a baya yana fallasa iskar gas tare da mafi ƙarancin gurbataccen ruwa zuwa mafi kyawun ruwa. Ana sanya nozzles da yawa a fadin hasumiyar a tsawo daban-daban don yayyafa duk iskar gas yayin da yake motsawa ta hanyar hasumiyar. Dalilin yin amfani da nozzles da yawa shine don kara yawan kyawawan droplets da ke tasiri ga ƙwayoyin gurbatawa da kuma samar da babban yanki don shan gas.

A ka'idar, karamin ɗigon ya samo asali, mafi girman yadda aka samu don gurɓataccen iskar gas da ƙwayoyin cuta. Koyaya, ɗigon ruwa dole ne ya zama babba don kada a fitar da shi daga mai tsabta ta hanyar iskar gas. Sabili da haka, hasumiyoyin fesawa suna amfani da nozzles waɗanda ke samar da ɗigon ruwa waɗanda yawanci 500-1000 μm a diamita. Kodayake ƙananan ne, waɗannan ɗigon suna da girma idan aka kwatanta da waɗanda aka kirkira a cikin Venturi scrubbers waɗanda ke da 10-50 μm a girman. Ana kiyaye saurin iskar gas, daga 0.3 zuwa 1.2 m / s (1-4 ft / s), don hana fitar da ɗigon ruwa daga hasumiyar.

 Tarin iskar gas 
Ana iya amfani da hasumiyoyin fure don shan gas, amma ba su da tasiri kamar hasumiyoyin da aka ɗora ko farantin. Hasumiyoyin fure na iya zama masu tasiri sosai wajen cire gurɓata idan gurɓataccen yana narkewa sosai ko kuma idan an kara sinadarin sinadarai a cikin ruwa.

Misali, ana amfani da hasumiyoyin fesawa don cire iskar HCl daga iskar gas a cikin masana'antar hydrochloric acid. A cikin samar da superphosphate da aka yi amfani da shi a cikin man fetur, ana fitar da iskar SiF4 da HF daga wurare daban-daban a cikin matakai. An yi amfani da hasumiyoyin fure don cire waɗannan mahadi masu narkewa sosai. Ana kuma amfani da hasumiyoyin fure don cire tsayi a cikin burodi da masana'antun masana'antu ta hanyar share iskar gas tare da maganin KMnO4.

 Matsalolin kiyayewa 
Babban fa'idar hasumiyoyin fesawa a kan sauran Masu tsaftacewa shine ƙirarsu gaba ɗaya; ba su da ɓangarorin ciki sai dai don nozzles na fesawa. Wannan fasalin yana kawar da yawancin matsalolin haɓaka da ke tattare da sauran masu tsabtacewa. Matsalolin kulawa na farko sune toshewar burodi ko rushewa, musamman lokacin amfani da ruwa mai tsabtace sake amfani. Don rage waɗannan matsalolin, ana amfani da tsarin daidaitawa ko tacewa don cire barbashi na abrasive daga ruwan da aka sake amfani da shi kafin a sake tura shi cikin nozzles.
