Ulwelwesi oluwomile kancane ukususwa kwe-gas sulfurization ubuchwepheshe buwubuchwepheshe bokususa i-flue gas desulfurization kuma-boilers anamandla angu-35T/H ~ 670T/H, futhi ukusebenza kahle kokususa i-sulfurization kungafinyelela ngaphezu kuka-85%.
Ukomisa ngesifutho ubuchwepheshe obusha be-FGD. Uma kuqhathaniswa nenqubo yokumanzisa, ukutshalwa kwayo kokuqala kuphansi, kodwa inani le-desulfurizer likhulu, ngakho-ke livame ukusetshenziswa kumalahle esibabule aphakathi naphansi (
Ukomisa ngesifutho ubuchwepheshe bokususa i-sulfurization isebenzisa umgomo wokomisa ngesifutho ukuze ifeze injongo ukususwa kwe-flue gasInqubo yokususa i-sulfurization yokomisa ngokufutha ihlukaniswe ngezinyathelo ezi-5: (1) ukulungiswa kokumunca; (2) i-atomization ye-slurry yokumunca; (3) ukuxhumana nokuxuba amaconsi enkungu kanye negesi yoketshezi; (4) ukumunca i-evaporation-sulfur dioxide; (5) ukususwa kwezinsalela zemfucuza, kanye nezinyathelo ezintathu 2, 3 kanye no-4 zonke zenziwa embhoshongweni wokumunca ngokufutha.
Uma i-atomized slurry ithinta igesi ye-flue embhoshongweni wokumunca, i-munctor iqala ukuhwamuka, igesi ye-flue iyaphola futhi ifuthwe, bese i-lime slurry isabela ne-SO2 ukuze yakhe umkhiqizo wempuphu eyomile. Ukusabela konke kuhlukaniswe kanje: I-SO2 imuncwa amaconsi ukuze yakhe i-calcium sulfite, eqina ngemva kokufinyelela ekugcwaleni; I-CaSO3 engxenyeni yesisombululo isabela nomoya-mpilo oqina emaconsi ukuze i-oxidize ibe yi-calcium sulfate, eqina. Njengoba i-calcium hydroxide eqina isetshenziswa ngesikhathi senqubo yokususa i-sulfurization, ama-calcium hydroxide amaningi aqina futhi ukuze kugcinwe ukusabela kokususwa kwe-sulfur dioxide kuqhubeka.
Kubhekiselwa ekomiseni okuhwamukayo kwamaconsi kanye nenqubo yokupholisa nokufaka umswakama kwegesi yolwelwesi. Ukomiswa kwamaconsi kuhlukaniswe cishe izigaba ezimbili: isigaba sokuqala ngokuyisisekelo ukuhwamuka kwamahhala kwamanzi ebusweni bamaconsi ngoba okuqukethwe okuqinile kumaconsi olwelwesi akukukhulu, futhi ijubane lokuhwamuka liyashesha futhi aliguquguquki. Njengoba amanzi ehwamuka, okuqukethwe okuqinile kwamaconsi kuyanda, kanti isigaba sesibili senzeka lapho kuvela okuqinile okukhulu ebusweni bamaconsi. Njengoba indawo yolwelwesi iba ncane, umswakama kumele usabalale usuka ngaphakathi kwenhlayiya ngokusebenzisa izinto eziqinile, izinga lokomisa liyancipha, izinga lokushisa leconsi liyakhuphuka futhi lisondele ekushiseni kwegesi yolwelwesi, futhi ekugcineni lihlukane negesi yolwelwesi ngenxa yokuhwamuka kwamanzi akuyo ukuze kwakheke izinhlayiya eziqinile.
Isikhathi esithathayo ukuze amaconsi ome kusukela ekuqaleni kokuhwamuka kwamanzi sibaluleke kakhulu kokubili ekwakhiweni kwe-absorber kanye nesilinganiso sokukhipha i-sulfurization. Izici ezithinta isikhathi sokomisa amaconsi usayizi wamaconsi, okuqukethwe kwamanzi amaconsi, kanye namanani okushisa afinyelela ekugcwalisweni kwe-adiabatic.
