Fasahar konewa ta catalytic

1 Fassarar Fasaha

Ci gaban tattalin arziki da zamantakewa da buƙatun masana'antu sun sa fasahar catalytic, musamman fasahar konewa, ta ƙara zama hanyar fasahar masana'antu da babu makawa, kuma tare da haɓaka rayuwar jama'a da haɓakar buƙatu, masana'antar haɓaka za ta ci gaba da shiga dubunnan mutane. gidaje, cikin rayuwar mutane. Nazarin konewa na catalytic ya fara ne daga gano tasirin tasirin platinum akan konewar methane. Konewar catalytic yana taka muhimmiyar rawa wajen inganta tsarin konewa, rage yawan zafin jiki, inganta cikakkiyar konewa, da hana samuwar abubuwa masu guba da cutarwa, kuma an yi amfani da shi sosai a fannoni da yawa na samar da masana'antu da rayuwar yau da kullun.

2.Jigon da fa'idodin konewar catalytic

Catalytic konewa ne na hali gas-m lokaci catalytic dauki, yana rage kunnawa makamashi na dauki tare da taimakon mai kara kuzari, sabõda haka, shi ne flameless konewa a wani low ƙonewa zazzabi na 200 ~ 300 ℃. Rashin iskar shaka na kwayoyin halitta yana faruwa a saman m mai kara kuzari, yayin da ake samar da CO2 da H2O, da kuma sakin zafi mai yawa, saboda ƙananan zafin jiki na oxygenation. Saboda haka, N2 a cikin iska an hana shi sosai don samar da babban zafin jiki NOx. Bugu da ƙari, saboda zaɓaɓɓen catalysis na mai kara kuzari, yana yiwuwa a iyakance tsarin iskar oxygen na abubuwan da ke dauke da nitrogen (RNH) a cikin man fetur, ta yadda yawancin su suna samar da nitrogen na kwayoyin halitta (N2).

Idan aka kwatanta da ƙonewar harshen wuta na gargajiya, ƙonewar catalytic yana da fa'idodi masu yawa:

(1) Yanayin zafi yana da ƙasa, yawan amfani da makamashi yana da ƙasa, konewa yana da sauƙi don zama barga, har ma da oxidation za a iya kammala ba tare da canja wurin zafi na waje ba bayan zafin wutar lantarki.

(2) Babban aikin tsarkakewa, ƙarancin ƙarancin gurɓataccen iska (kamar NOx da samfuran konewa da ba su cika ba, da sauransu).

(3) Babban kewayon maida hankali na iskar oxygen, ƙaramar amo, babu gurɓataccen gurɓataccen abu, matsakaicin konewa, ƙarancin farashin aiki, da gudanar da aiki mai dacewa.

3 Aikace-aikacen Fasaha

Tsarin samar da petrochemical, fenti, electroplating, bugu, sutura, masana'antar taya da sauran masana'antu duk sun haɗa da amfani da fitar da mahaɗan maras tabbas. Abubuwan da ke da lahani masu lalacewa yawanci mahaɗan hydrocarbon, oxygen-dauke da kwayoyin halitta, chlorine, sulfur, phosphorus da halogen kwayoyin mahadi. Idan an fitar da waɗannan mahaɗaɗɗen ƙwayoyin cuta kai tsaye zuwa cikin sararin samaniya ba tare da magani ba, za su haifar da mummunar gurɓatar muhalli. Hanyoyin magance sharar iskar gas na gargajiya na gargajiya (kamar adsorption, condensation, konewa kai tsaye, da sauransu) suna da lahani, kamar sauƙi don haifar da gurɓataccen gurɓataccen abu. Domin shawo kan lahani na hanyoyin magance sharar iskar gas na gargajiya, ana amfani da hanyar konewa na catalytic don tsarkake iskar iskar gas.

Catalytic konewa hanya ne m da sauki Organic sharar gida fasahar tsarkakewa, da fasaha ne zurfin hadawan abu da iskar sharar kwayoyin kwayoyin a saman da mai kara kuzari a cikin m carbon dioxide da ruwa hanya, kuma aka sani da catalytic cikakken hadawan abu da iskar sharar iskar sharar iskar sharar iskar sharar gas hanya. Ƙirƙirar da ke da alaƙa da fasahar konewa ta catalytic don iskar gas ɗin benzene masana'antu, wanda ke amfani da ƙaramin ƙarfe mara tsada mara tsada, wanda ya ƙunshi CuO, MnO2, Cu-manganese spinel, ZrO2, CeO2, zirconium da cerium m bayani, wanda iya ƙwarai rage dauki zafin jiki na catalytic konewa, inganta catalytic aiki, da kuma ƙwarai mika rayuwar mai kara kuzari.The ƙirƙira dangantaka da wani catalytic konewa mai kara kuzari, wanda shi ne mai catalytic konewa kara kuzari ga tsarkakewa magani na Organic sharar gida gas, kuma ya ƙunshi. na wani blocky saƙar zuma yumbu m kwarangwal, wani shafi a kan shi da kuma daraja karfe aiki part.The shafi na mai kara kuzari ya hada da wani hadadden oxide kafa ta Al2O3, SiO2 da daya ko dama alkaline duniya karfe oxides, don haka yana da kyau high zafin jiki. juriya. Abubuwan da ke aiki na karafa masu daraja ana ɗora su ta hanyar impregnation, kuma ƙimar amfani mai inganci yana da girma.
