Okwangoku, uxinzelelo lokusingqongileyo lwesityalo esijikelezayo sokwenza intsimbi yesithando somlilo sikhulu. Phakathi kwabo, inkqubo yokususa uthuli yegesi ye-furnace flue ejikelezayo iyona nto iphambili, kwaye kuyimfuneko ukuphumeza ukuguqulwa okucocekileyo ukufezekisa ukukhutshwa kwe-ultra-low. Ngoko ke, ukukhethwa kunye nokusetyenziswa kweteknoloji esebenzayo, ekhuselekileyo kunye nephantsi yokusetyenziswa kwe-furnace dedusting ibe sisihloko esiphuthumayo kumashishini esinyithi kunye nentsimbi.
Indlela emanzi kunye nendlela eyomileyo yokujikeleza i-furnace flue gas dedusting ineenzuzo zabo
Itekhnoloji ejikelezayo yokususa itekhnoloji yesithando somlilo ifinyeziwe njenge-OG. I-OG sisishunqulelo se-Oxygen ejikeleza iziko loBuyiselo lweGesi ngesiNgesi, nto leyo ethetha ukubuyiswa kwegesi yesithando somlilo esijikelezayo. Isithando somlilo esijikelezayo sisebenzisa iteknoloji ye-OG ivelisa inani elikhulu lobushushu obuphezulu kunye ne-high-concentration ye-CO yegesi ye-flue kwisithando somlilo ngenxa ye-reaction oxidation enobudlova ngexesha lokuvuthela. I-flue gas icinezela ukungena komoya ojikelezayo ngokuphakamisa i-skirt kunye nokulawulwa koxinzelelo lwegesi ye-flue ngaphakathi kwe-hood. Kwimeko yokungatshiswa, iteknoloji ithatha i-vaporization cooling flue ukuze ipholise igesi ye-flue, kwaye emva kokuhlanjululwa yi-Venturi ye-tube yokuqokelela uthuli, ingena kwi-gas recovery and release system.
Ukujikeleza kwesithando somlilo esomileyo iteknoloji yokususa uthuli ifinyeziwe njengeLT. ILTindlela yaphuhliswa ngokudibeneyo nguLurgi noThyssen eJamani.LTsisishunqulelo samagama eenkampani ezimbini. Le teknoloji isebenzisa i-vaporization epholileyo ukupholisa igesi ye-flue, kwaye emva kokuhlanjululwa yi-cylindrical dry electrostatic precipitator, ingena kwi-gas recovery and release system. Lo mthetho waqala ukusetyenziswa kwiiprojekthi zokubuyisela igesi kwi-1981.
Ukujikeleza eziko elomileyo dedusting iteknoloji inotyalo-mali olukhulu lwexesha elinye, isakhiwo esintsonkothileyo, izinto ezininzi ezityiwayo, kunye nobunzima obuphezulu bobugcisa. Izinga lokunyuswa kweemarike kwilizwe lam lingaphantsi kwama-20%. Ngapha koko, itekhnoloji yokususa uthuli olomileyo isebenzisa i-electrostatic precipitator enkulu eyomileyo ukususa uthuli olujikelezayo lweziko lomlilo. Umqokeleli wothuli kulula ukuqokelela uthuli kwaye ukukhutshwa kothuli akuzinzile.
Xa kuthelekiswa nenkqubo yokususa uthuli olomileyo, inkqubo ye-OG yokususa uthuli olumanzi inesakhiwo esilula, indleko ephantsi, kunye nokusebenza kakuhle kokucoca, kodwa ineziphene ezifana nokusetyenziswa kwamandla aphezulu, ukusetyenziswa kwamanzi amakhulu, ukucocwa kogutyulo olunzima, kunye neendleko eziphezulu zokusebenza. Ngaphezu koko, itekhnoloji yokususa uthuli olumanzi ihlamba lonke uthuli emanzini kungakhathaliseki ubungakanani bamasuntswana, okukhokelela kumthamo omkhulu wokuthuthwa kwamanzi amdaka. Nangona inqanaba lobuchwephesha leenkqubo zokukhupha inkunkuma eyomileyo nemanzi iye yaphuculwa ngokuqhubekayo kwinkqubo yokwenziwa kwalapha ekhaya, iziphene zazo ezihambelanayo azikasonjululwa.
Ukuphendula le meko ingentla, iingcali zoshishino ziye zaphakamisa itekhnoloji yokususa uthuli eyomileyo kwiminyaka yakutshanje, ethe yakhuthazwa eTshayina. Okwangoku, inani leziko elijikelezayo lisebenzisa itekhnoloji yokulahla i-semi-dry dedusting lidlula inani leziko elijikelezayo lisebenzisa itekhnoloji yokulahla ezomileyo. Inkqubo yokukhupha i-semi-dry inkqubo yokukhupha i-semi-dry isebenzisa i-cooler ephuphumayo eyomileyo ukubuyisela i-20% -25% yothuthu olomileyo, egcina izibonelelo zokukhupha inkunkuma emanzi kwaye yoyise iziphene zobuchwephesha bokukhupha inkunkuma eyomileyo nemanzi. Ngokukodwa, obu buchwephesha bunokuguqula inkqubo yokugxothwa okumanzi ngaphandle kokuyidiliza ngokupheleleyo kwaye yenziwe kwakhona njengenkqubo yokukhupha inkunkuma eyomileyo, ukuze izibonelelo zokuqala zigcinwe ngowona mlinganiselo mkhulu kwaye iindleko zotyalo-mali zinokugcinwa.
