Pupuhi maroke-haurua te whakakorenga hau Ko te hangarau he hangarau whakakorenga hau paru mō ngā kohua me te kaha o te 35T/H ~ 670T/H, ā, ka taea e te whai huatanga whakakorenga te eke ki te neke atu i te 85%.
He hangarau FGD hou te whakamaroke rehu. Ki te whakatauritea ki te tukanga mākū, he iti te haumitanga tuatahi, engari he nui te nui o te desulfurizer, nō reira he maha te whakamahinga i roto i te waro whanariki reo-rahi me te iti-rahi (
Te whakamaroke rehu hangarau whakakorenga whanariki e whakamahi ana i te kaupapa o te whakamaroke rehu hei whakatutuki i te kaupapa o te whakakorenga whanariki o te hau paruE rima ngā taahiraa o te tukanga whakamaroke rehu: (1) te whakarite mimiti; (2) te whakakorikori i te paru mimiti; (3) te whakapā atu me te whakaranu i ngā pata kohu me te hau paru; (4) te mimiti i te mimiti me te hauhā whanariki; (5) te tango i ngā toenga para, ā, ko ngā taahiraa e toru 2, 3 me te 4 ka mahia katoatia i roto i te pourewa mimiti rehu.
Ina pā te paru kua whakakāhia ki te hau para i roto i te pourewa mimiti, ka tīmata te mimiti ki te mimiti, ka whakamataohia, ka whakamakukuhia te hau para, ā, ka tauhohe te paru raima ki te SO2 hei hanga i te paura maroke. Ka wehea te tauhohenga katoa ki: Ka mimitihia te SO2 e ngā pata hei hanga i te konupūmā whanariki, ka whakakōkī i muri i te taenga ki te mākū; Ka tauhohe te CaSO3 i roto i tētahi wāhanga o te otinga ki te hāora kua rewa i roto i ngā pata hei waikura hei konupūmā whanariki, ka whakakōkī ki waho. I te paunga o te konupūmā hauwaiwai kua rewa i te wā o te tukanga whakakorenga whanariki, ka rewa anō ngā totoka konupūmā hauwaiwai hei pupuri i te tauhohenga tango hauhā whanariki.
E pā ana ki te whakamaroke mimiti o ngā pata me te tukanga whakamatao me te whakamakuku o te hau paru. E rua ngā wāhanga o te whakamaroke i ngā pata: ko te wāhanga tuatahi ko te mimiti noa o te wai i runga i te mata o ngā pata nā te mea he iti te nui o te totoka i roto i ngā pata paru, ā, he tere, he pumau te tere mimiti. I te mimiti o te wai, ka piki ake te nui o ngā totoka o ngā pata, ā, ko te wāhanga tuarua ka puta mai he totoka nui ki runga i te mata o ngā pata. I te iti haere o te mata mimiti, me horapa te makuku ki waho mai i roto o te matūriki mā roto i te rauemi totoka, ka heke te tere whakamaroke, ka piki ake te pāmahana o te pata ka tata ki te pāmahana o te hau paru, ā, i te mutunga ka wehe atu i te hau paru nā te mimiti o te wai i roto hei hanga i ngā matūriki totoka.
He mea tino nui te roa o te wā e maroke ai ngā pata mai i te tīmatanga o te mimiti mō te hoahoa o te mea mimiti me te tere o te tango whanariki. Ko ngā mea e pā ana ki te wā maroke o te pata ko te rahi o te pata, te nui o te wai o te pata, me ngā uara pāmahana ki te taumata adiabatic.
