SO2 bụ otu n'ime isi ihe na-emetọ ikuku na ihe ngosi njikwa dị mkpa nke mmetọ gas na-ekpofu ụlọ ọrụ na China. Ka ọ dị ugbu a, ụlọ ọrụ niile na-agba ọkụ na China emejuputala ọrụ desulfurization flue gas, n'etiti teknụzụ desulfurization kachasị bụ limestone / gypsum wet flue gas desulfurization (WFGD). N'ime usoro a, a na-eji slurry limestone mee ihe dị ka ihe na-anabata ya, bụ nke na-adịghị na kọntaktị na flue gas na ụlọ elu desulfurization wee gwakọta ya nke ọma. Mgbe SO2 dị na flue gas jiri ihe na-amịkọrọ ihe meghachi omume, ọ na-eji kemịkal emeghachi omume na ikuku oxidizing nke onye na-eme ihe na-eme ihe na-eme ka ọ bụrụ gypsum.

E nwere slurry tank na ala nke absorption ụlọ elu, na ọhụrụ absorbent na-pumped n'ime slurry tank site a limestone nri slurry mgbapụta; n'okpuru ọrụ nke agitator, ọ na-agwakọta ya na slurry dị na tankị slurry; Mgbe ahụ, mgbapụta slurry na-ekesa ga-ebuli slurry agwakọta na oyi akwa ma fesa ya ka ọ kpọtụrụ gas flue na-asọba ugbu a. Imeju nke ọma na n'oge nke ihe mmịkọ ọhụrụ dị oke mkpa n'oge usoro niile. Ọ bụrụ na mgbakwunye ego ezughi oke, ọ na-esiri ike ịkwado arụmọrụ desulfurization; ma ọ bụrụ na ego mgbakwunye dị oke elu, ọ ga-ebelata ọnụ ọgụgụ ojiji nke ihe na-adọrọ adọrọ, ma na-emetụta àgwà nke desulfurization site-products. Ya mere, njikwa mgbapụta limestone slurry bụ akụkụ dị mkpa nke ọrụ FGD.

Ⅱ Pumps chọrọ site na nhazi usoro

1. Usoro nkwadebe limestone

2. Pump maka usoro ụlọ elu absorption

3. Flue gas usoro

4. Mgbapu maka gypsum dewatering usoro

5. Nfuli maka usoro nkwụsị

6. Nfuli maka usoro ọgwụgwọ mmiri mkpofu

Ewezuga sistemu gas flue, sistemu ndị dị n'elu ga-achọ nfuli slurry. N'ime usoro ụlọ elu absorption, olu injection dị ntakịrị, ya mere dayameta nke mgbapụta ahụ dị ntakịrị. The nfuli na akụkụ a bụ nnukwu-ọnụ ọgụgụ pụrụ iche nfuli e mere maka desulfurization, na nfuli eji na ndị ọzọ usoro bụ anyị na-ejikarị obere na ọkara-sized slurry nfuli. Dị ka ọnọdụ nke slurry si dị, ihe a na-ahọrọ nke akụkụ ndị na-asọpụta bụ ma na-eguzogide ọgwụ na corrosion.
