Njengemishini evamile yamandla, amajeneretha omusi adlala indima ebalulekile ekuthuthukiseni umnotho. Kodwa-ke, izinto eziyingozi eziqukethwe yi-flue gas yamajeneretha omusi zingcolisa imvelo futhi zisongela impilo yezakhamuzi. Indlela yokwelapha i-steam generator flue gas ukuhlanza i-steam generator flue gas ukuze ukukhishwa kuhlangabezane nezindinganiso. Ngakho yiziphi izindlela zokwelapha i-steam generator flue gas? I-Nobeth wumkhiqizo ohlinzeka ngesethi ephelele yezixazululo ze-steam generator. Iphinde ibe nocwaningo olujulile ngezindlela zokwelashwa kwegesi ye-steam generator flue. Kufingqiwe lapha futhi kunethemba lokusiza wonke umuntu.
Ngokwemithetho efanele mayelana nokungcoliswa komoya obhayela, izinkinga zamanje zokwelashwa kwegesi ephehla umusi ezimbonini ikakhulukazi ama-sulfide, ama-nitrogen oxides, nothuli lwentuthu, kanye nezindlela ezihlukene zokwelashwa kwegesi ekhiqiza umusi ephuma emshinini kufanele zamukelwe ngokulandelana.
1. I-Desulfurization yezindlela zokwelapha igesi ye-steam generator flue
Ngokohlobo lwe-desulfurizer, izindlela ze-steam generator flue desulfurization zihlanganisa indlela ye-calcium esekelwe ku-CaCO3 (i-limestone), indlela ye-magnesium esekelwe ku-MgO, indlela ye-sodium esekelwe ku-Na2S03, kanye nendlela ye-ammonia esekelwe ku-NH3. , indlela ye-alkali ephilayo esekelwe ku-alkali ephilayo. Phakathi kwazo, ubuchwepheshe bezohwebo obusetshenziswa kakhulu emhlabeni yindlela ye-calcium, ebalelwa ngaphezu kwama-90%.
2. Indlela yokwelapha igesi ye-steam generator flue: denitrification
Ubuchwepheshe be-Denitrification ikakhulukazi buhlanganisa ubuchwepheshe bokushiswa kwe-nitrogen ephansi, ubuchwepheshe be-SNCR denitrification, ubuchwepheshe be-SCR denitrification, ubuchwepheshe be-ozone oxidation denitrification, njll. Ama-boilers ahlukene angasebenzisa izindlela ezahlukene zokwelashwa kwe-boiler flue gas.
3. Indlela yokwelapha igesi ye-steam generator flue: ukususwa kothuli
Izinhlayiya zentuthu nothuli kugesi ekhipha amandla omlilo weziko lokuphehla isitimu kuphathwa ngeziqongo zothuli ezikhiqiza isitimu. Iziqoqi zothuli ezikhiqiza isitimu ezimbonini ezivame ukusetshenziswa zihlanganisa abaqoqi bothuli be-gravity sedimentation, abaqoqi bothuli lwe-cyclone, abaqoqi bothuli olunomthelela, abaqoqi bothuli befilimu yamanzi be-centrifugal, njll. Njengoba izidingo zokuvikela imvelo ziba nzima kakhulu, ukusetshenziswa kweziqoqi zothuli lwezikhwama kanye ne-electrostatic precipitators kuzokhula kancane kancane. Njengamanje, abaqoqi bezintuli ezikhiqiza isitimu ezimbonini ezisetshenziswa kakhulu kumajeneretha esitimu ezimbonini futhi ezingahlangabezana nezidingo zamazinga okukhishwa kwentuthu nothuli ikakhulukazi abaqoqi bamashubhu othuli lwe-cyclone kanye nabaqoqi bamafilimu amanzi.
