Ukususwa kwe-sulphur dioxide ku-flue gas ngokumisa isifutho, ukusetshenziswa kobuchwepheshe be-spray drying desulphurization ekuvikelweni kwemvelo, ukuxhashazwa okunengqondo kanye nokusetshenziswa kwenani elikhulu le-sulfate eyimpuphu.

Ukususwa kwe-sulphur dioxide ku-flue gas ngokumisa isifutho, ukusetshenziswa kobuchwepheshe be-spray drying desulphurization ekuvikelweni kwemvelo, ukuxhashazwa okunengqondo kanye nokusetshenziswa kwenani elikhulu le-sulfate eyimpuphu.

Abstract:

Imfuneko ebalulekile ekusetshenzisweni okubanzi kobuchwepheshe be-spray-dried gum sulfur ukuthi ingakwazi yini ukuxazulula inkinga yokuthuthukiswa okunengqondo kanye nokusetshenziswa kwenani elikhulu le-powder sulfate ngemva kokumiswa. Ingavuselelwa njengesimunyisi, ingxenye yento eyomile ingaphinda igaywe kabusha, njengoba izithasiselo zomhlaba, ziguqulwa zibe i-agent yokunamathisela esetshenziselwa ukubuyisela usimende, eyenziwe ngegravel yokwenziwa ye-granular ...

Njengoba ukusetshenziswa kwamandla omhlaba kukhula unyaka nonyaka, ukushiswa nokusetshenziswa kwamalahle njengomthombo wamandla oyinhloko, akhipha isamba esikhulu se-sulphur dioxide kanye nokwakheka kwemvula ye-asidi yesifunda, kuye kwabangela ukungcoliswa okukhulu kwemvelo, okuphazamisa imvelo. ibhalansi yemvelo, okubangela ukucekelwa phansi okukhulu kwamahlathi, i-acidification yenhlabathi namachibi, nokugqwala kwezakhiwo.

Ngakho-ke, ukulawula nokunciphisa ukukhishwa kwe-sulphur dioxide kuwumsebenzi obalulekile. Phakathi kobuchwepheshe obuningi be-desulfurization, ukusetshenziswa kwendlela yokumisa isifutho ukuze kukhishwe i-sulphur dioxide egesini e-flue ubuchwepheshe obuthola ukunakwa okwengeziwe. Lobu buchwepheshe baqala ukufundwa ngawo-1970 futhi bafakwa ekusebenzeni kwezohwebo ngasekupheleni kwawo-1970. Inotshalomali oluncane, ukusebenza okulula, ukusebenza kahle kokususwa kwesibabule okuphezulu, akukho ukungcoliswa kwesibili, futhi uma kuqhathaniswa nendlela emanzi esetshenziswa ngobuningi ku-flue gas desulfurization, imikhiqizo yempushana eyakhiwe ngendlela yokumisa isifutho ye-desulfurization inokukhetha okukhulu kanye nenani lokuthuthukiswa.

I-spray drying gel sulfur technology ingasetshenziswa kabanzi imfuneko ebalulekile ukuthi ingakwazi yini ukuxazulula ukuthuthukiswa okunengqondo nokusetshenziswa kwenani elikhulu le-powder sulfate ngemva kokumiswa. Ingavuselelwa njenge-absorbent, ingxenye yento eyomile ingaphinda igaywe kabusha, njengesengezo emhlabeni, iguqulwe ibe i-agent yokunamathisela ye-cement retardant, eyenziwe ngesihlabathi sokwenziwa esiyimbudumbudu kanye netshe, njengesigcwalisi sezinto zokwakha esikhundleni sokusetshenziswa okujwayelekile. ukhonkolo kanye netiyela nokunye.
