Ulwelo olomileyo kancinci ukususwa kwe-gesi kwi-sulfurization Iteknoloji yiteknoloji yokususa i-flue gas desulfurization kwiibhoyila ezinomthamo we-35T/H ~ 670T/H, kwaye ukusebenza kakuhle kokususa i-sulfurization kunokufikelela ngaphezulu kwe-85%.
Ukomisa ngokutshiza bubuchwepheshe obutsha be-FGD. Xa kuthelekiswa nenkqubo yokumanzisa, utyalo-mali lwayo lokuqala luphantsi, kodwa ubungakanani be-desulfurizer bukhulu, ngoko ke isetyenziswa rhoqo kumalahle esulfuri aphakathi naphantsi (
Ukomisa ngespray iteknoloji yokususa i-sulfurization isebenzisa umgaqo wokomisa nge-spray ukufezekisa injongo ukususwa kwe-flue gasInkqubo yokususa i-sulfurization yokutshiza yahlulwe yangamanyathelo ama-5: (1) ukulungiswa kokufunxa; (2) i-atomization ye-slurry yokufunxa; (3) ukudibana kunye nokuxutywa kwamaconsi enkungu kunye negesi yolwelo; (4) ukufunxwa kwe-evaporation-sulfur dioxide; (5) ukususwa kwenkunkuma, kwaye amanyathelo amathathu 2, 3 kunye no-4 onke enziwa kwinqaba yokufunxa i-spray.
Xa i-atomized slurry idibana ne-flue gas kwi-absorption tower, i-absorbent iqala ukufuma, i-flue gas iyaphola kwaye ifume, kwaye i-lime slurry iphendula ne-SO2 ukwenza imveliso yomgubo owomileyo. Lonke ulwahlulo lwahlulwe ngolu hlobo: I-SO2 ifunxwa ngamathontsi ukwenza i-calcium sulfite, ejika ibe yikristale emva kokufikelela kubunzulu; I-CaSO3 kwinxalenye yesisombululo iphendula ne-oxygen ejika ibe yi-calcium sulfate, ejika ibe yikristale. Njengoko i-calcium hydroxide enyibilikisiweyo isetyenziswa ngexesha lenkqubo yokususa i-sulfurization, ezinye izinto eziqinileyo ze-calcium hydroxide ziyanyibilika ngakumbi ukuze kugcinwe i-sulfur dioxide removal reaction.
Ibhekisa ekomiseni ngokuphuma kwamanzi kumathontsi kunye nenkqubo yokupholisa nokufumisa igesi yombhobho. Ukomiswa kwamathontsi kwahlulwe ngamanqanaba amabini: isigaba sokuqala ngokusisiseko kukuphuma kwamanzi ngokukhululekileyo kumphezulu wamathontsi kuba umxholo oqinileyo kumathontsi okudaka awukhulu, kwaye isantya sokuphuma kwamanzi siyakhawuleza kwaye asiguquguquki. Njengoko amanzi ephuma, umxholo wezinto eziqinileyo zamathontsi uyanda, kwaye isigaba sesibini senzeka xa kuvela izinto eziqinileyo ezibalulekileyo kumphezulu wamathontsi. Njengoko indawo yomphezulu wokuphuma kwamanzi iba ncinci, ukufuma kufuneka kudlulele ngaphandle ukusuka ngaphakathi kwesuntswana ngokusebenzisa izinto eziqinileyo, izinga lokomisa liyancipha, ubushushu beconsi buyanda kwaye busondela kubushushu begesi yombhobho, kwaye ekugqibeleni yahlukane negesi yombhobho ngenxa yokuphuma kwamanzi kuyo ukuze yenze amasuntswana aqinileyo.
Ixesha elithathwayo ukuze amathontsi ome ukususela ekuqaleni kokufuma libaluleke kakhulu kuyilo lwe-absorber kunye nesantya sokukhupha i-sulfurization. Izinto ezichaphazela ixesha lokomisa amathontsi bubungakanani bamathontsi, umxholo wamanzi amathontsi, kunye namaxabiso obushushu ukuya kutsho kwi-adiabatic saturation.
