Ubuchwepheshe obuthuthukisiwe bokubuyiswa kokushisa kwebanga eliphansi ezitshalweni ze-sulfuric acid

Uhlelo olusezingeni eliphansi lokubuyisela ukushisa luqukethe isibambisi sokushisa esiphezulu, iphampu ejikelezayo yokushisa ephezulu, ijeneretha yesteam, nesifudumezi samanzi sokuphakelayo.

Igesi eyisisekelo eguquliwe isuka esigabeni sokuguqula ingena ngaphansi kwesibambisi sokushisa okuphezulu, lapho izinga lokushisa eliphezulu eligxiliswe i-sulfuric acid (99%) lifuthwa ukusuka phezulu, ukuze limunce i-SO3, emva kwalokho iphampu ye-asidi ejikelezayo ingene kujeneretha wesimusi. ukushisa amanzi okuphakelayo kubhayela ukuze kukhiqizwe isitimu somfutho ophansi. I-asidi epholile izoxutshwa namanzi ukuze ijikeleze. I-sulfuric acid egcwele izinga lokushisa eliphezulu kakhulu izokhishwa lapho kuphuma umshini wokuphehla isitimu bese kuyiwa ku-heater yamanzi ezopholiswa ngaphambi kokuya emkhunjini ojikelezayo we-asidi engxenyeni yokomisa nokumuncwa. Ngemva kokumuncwa, igesi izoya esigabeni sokuguqulwa ilinde ukuguqulwa kwesibili.

1: I-heater kabhayela

2:Ijeneretha yomthungo

3: Iphampu ye-asidi ejikelezayo

4:Ithangi le-asidi elijikelezayo

5: Umbhoshongo odonsa amanzi

Inzuzo enkulu ukuthi ingakhuphula isizukulwane se-steam ngo-0.4-0.5t/ton sulfuric acid

Lobu buchwepheshe bamukelwe izitshalo ze-sulfuric acid ezingaphezu kuka-50 ezinamandla okukhiqiza asukela ku-100kt/a kuya ku-800kt/a.
