Okwangoku, uxinzelelo lokhuseleko lokusingqongileyo lwesityalo sokwenza intsimbi sesithando esijikelezayo lukhulu kakhulu. Phakathi kwazo, inkqubo yokususa uthuli lwegesi ye-flue yesithando esijikelezayo yeyona nto iphambili, kwaye kuyimfuneko ukwenza utshintsho olucocekileyo ukuze kufezekiswe ukukhutshwa komoya okuphantsi kakhulu. Ke ngoko, ukukhethwa nokusetyenziswa kwetekhnoloji yokukhupha uthuli yesithando esijikelezayo esebenzayo, ekhuselekileyo nengasetyenziswa kakhulu iye yaba yingongoma engxamisekileyo kumashishini esinyithi nesinyithi.
Indlela emanzi kunye nendlela eyomileyo yokukhupha uthuli kwi-oven flue gas ineenzuzo zayo
Iteknoloji yokukhupha uthuli olumanzi kwi-furnace ejikelezayo ifinyezwa ngokuthi yi-OG. I-OG sisifinyezo se-Oxygen rotation furnace Gas Recovery ngesiNgesi, nto leyo ethetha ukubuyiswa kwegesi kwi-furnace ejikelezayo ye-oxygen. I-furnace ejikelezayo esebenzisa iteknoloji ye-OG ivelisa inani elikhulu legesi ye-CO2 flue eshushu kakhulu nexineneyo kwi-furnace ngenxa ye-oxidation reaction enamandla ngexesha lokuvuthela. Igesi ye-flue icinezela ukungena komoya ojikelezileyo ngokuphakamisa isiketi kunye nolawulo loxinzelelo lwegesi ye-flue ngaphakathi kwi-hood. Kwimeko yokuba ingatshanga, iteknoloji isebenzisa i-vaporization cooling flue ukuze ipholise igesi ye-flue, kwaye emva kokuba icociwe yi-Venturi tube dust collector enamanqanaba amabini, ingena kwinkqubo yokubuyisela nokukhulula igesi.
Itekhnoloji yokususa uthuli olomileyo kwi-oven ejikelezayo ifinyeziwe ngolu hloboLT. ILTLe ndlela yaphuhliswa ngokubambisana nguLurgi noThyssen eJamani.LTsisifinyezo samagama eenkampani ezimbini. Le teknoloji isebenzisa i-vaporization cooler ukupholisa igesi yolwelo, kwaye emva kokuba icociwe yi-cylindrical dry electrostatic precipitator, ingena kwinkqubo yokubuyisela nokukhulula igesi. Lo mthetho waqala ukusetyenziswa kwiiprojekthi zokubuyisela igesi ngo-1981.
Itekhnoloji yokukhupha uthuli olujikelezileyo olusebenzisa i-oven dry dedusting inotyalo-mali olukhulu oluvela kube kanye, isakhiwo esintsonkothileyo, izinto ezininzi ezisetyenziswayo, kunye nobunzima obukhulu kwezobuchwepheshe. Izinga lokukhuthazwa kwemarike kwilizwe lam lingaphantsi kwama-20%. Ngaphezu koko, itekhnoloji yokususa uthuli olomileyo isebenzisa i-electrostatic precipitator enkulu eyomileyo ukususa uthuli lwe-oven primary rotating dust. Kulula ukuqokelela uthuli kwaye uthuli oluphumayo aluzinzanga.
Xa kuthelekiswa nenkqubo yokususa uthuli olomileyo, inkqubo yokususa uthuli olumanzi ye-OG inesakhiwo esilula, ixabiso eliphantsi, kunye nokusebenza kakuhle kokucoca, kodwa ineengxaki ezifana nokusetyenziswa kwamandla aphezulu, ukusetyenziswa kwamanzi amaninzi, unyango olunzima lwelindle, kunye neendleko eziphezulu zokusebenza. Ngaphezu koko, iteknoloji yokususa uthuli olumanzi ihlamba lonke uthuli emanzini kungakhathaliseki ubungakanani bamasuntswana, nto leyo ebangela ukuba kubekho inani elikhulu lamanzi amdaka okususa uthuli. Nangona inqanaba lobuchwephesha leenkqubo zokususa uthuli olomileyo nolumanzi liye laphuculwa rhoqo kwinkqubo yokwenziwa kwendawo, iziphene zazo azikasonjululwa.
Ukuphendula le meko ingasentla, iingcali zoshishino ziye zacebisa iteknoloji yokususa uthuli olomileyo kwiminyaka yakutshanje, ebikhuthazwa eTshayina. Okwangoku, inani lezitofu ezijikelezayo ezisebenzisa iteknoloji yokususa uthuli olomileyo lidlula inani lezitofu ezijikelezayo ezisebenzisa iteknoloji yokususa uthuli olomileyo. Inkqubo yokususa uthuli olomileyo isebenzisa i-dry evaporative cooler ukubuyisela i-20%-25% yothuthu olomileyo, olugcina iingenelo zokususa uthuli olumanzi kwaye loyise iziphene zobuchwepheshe bokususa uthuli olomileyo nolumanzi. Ngokukodwa, le teknoloji inokuguqula inkqubo yokususa uthuli olumanzi ngaphandle kokufuna ukuyiqhaqha ngokupheleleyo nokuyiphinda njengenkqubo yokususa uthuli olomileyo, ukuze izakhiwo zokuqala zigcinwe kangangoko kwaye iindleko zotyalo-mali zigcinwe.
