Isifutho Sokususa I-sulfurization

II. Izindawo Ezintathu Ezisebenzayo Ze-Desulfurization Absorber

I-absorber ingahlukaniswa ngezindawo ezintathu ezisebenzayo kusukela phezulu kuya phansi: i-oxidation crystallization, i-absorbency kanye ne-demisting zone.

(1) Indawo yokwenza i-oxidation crystallization ibhekisela echibini lokudaka lomfaki-zinyo, futhi umsebenzi walo oyinhloko ukuncibilikisa i-limestone nokuxova i-calcium sulfite.

(2) Indawo yokumunca ifaka phakathi indawo yokungena yommunca, ithileyi kanye nezendlalelo eziningana zezifutho. Kunezimbobo eziningi zekhoni ezingenalutho kungqimba ngayinye yedivayisi yokufutha; umsebenzi oyinhloko wesifutho usekelwe ekungcoleni okune-asidi kanye nokumunca umlotha wempukane kugesi yomoya.

(3) Indawo yokususa igesi inezinhlayiya zezigaba ezimbili ngaphezu kwesendlalelo sokufafaza. Umsebenzi wayo oyinhloko ukuhlukanisa amaconsi egesi yokukhipha igesi, ukunciphisa umthelela emishinini engezansi kanye nomthamo wokumunca.

Indawo yokumunca ye-absorber ibhekisela endaweni ephakathi komugqa ophakathi nendawo yokungena kwe-absorber kanye nowesendlalelo esiphezulu sokufafaza. I-slurry efafaziwe igeza igesi yomoya equkethe isibabule kule ndawo. Ukuphakama okwanele kwendawo yokumunca kuqinisekisa izinga eliphezulu lokumunca. Uma ukuphakama kuphakeme, izinga lokugeleza kwephampu yokujikeleza elidingekayo liphansi Ngaphansi kwesidingo esifanayo ngesilinganiso sokumunca.

Indawo yokufafaza ye-absorber ichazwa kanje:

(1) Umbhoshongo wokufutha: 1.5m ngaphansi komlomo ophansi kakhulu endaweni yokuphuma komlomo ophakeme kakhulu.

(2) Umbhoshongo wekholomu yoketshezi: kusukela endaweni yokukhipha i-nozzle ephansi kakhulu kuya ku-0.5m ngaphezu kwekholomu yoketshezi ephezulu kakhulu lapho wonke amaphampu okujikeleza kwe-slurry esebenza.

I-absorber iyithuluzi eliyinhloko lesistimu yokususa igesi yolwelo. Idinga indawo enkulu yokuxhumana negesi nolwelo, ukusabela okuhle kokumuncwa kwegesi, ukulahlekelwa okuncane kwengcindezi. Ifanele ukwelashwa kwegesi yolwelo enamandla amakhulu. Izinyathelo ezilandelayo zenqubo eziyinhloko ziyaqedwa kule divayisi:

① Ukumuncwa kwamagesi ayingozi edakeni lokuwasha;

② Ukuhlukaniswa kwegesi yoketshezi kanye ne-washing slurry;

③ Ukungaguquguquki kodaka;

④ Ukufakwa kwe-oxidation kwemikhiqizo yokungathathi hlangothi okuphakathi ibe yi-gypsum;

⑤ Ukwakheka kwe-Gypsum crystallization.

III. Ukwakheka kwe-Absorber

I-absorber ngokuvamile ihlukaniswe ibe yi-cylinder, i-flue gas inlet kanye ne-flue gas outlet ngesakhiwo. I-flue gas inlet kanye ne-outlet zibekwe phakathi kwe-absorber kanye naphezulu kwe-absorber ngendlela efanayo. I-absorber cylinder ingahlukaniswa ibe yi-slurry pool, i-spray layer kanye nendawo yokukhipha amanzi esebenza. I-slurry pool itholakala engxenyeni engezansi ye-absorber inlet ngokuvamile, kanti i-spray layer kanye ne-demister kutholakala phakathi kwe-flue gas inlet kanye ne-outlet. I-flue gas outlet ye-absorber ingaba yi-outlet ephezulu eqondile noma i-outlet eseceleni evundlile.

Indawo yokufutha evamile inezendlalelo zokufutha kanye nama-nozzle kanye namanye amadivayisi. Kuye ngenqubo yokukhuculula, indawo yokufutha yezinye izifutho izophinde ifakwe amathileyi, izinduku zeVenturi kanye namanye amadivayisi.

IV. Izidingo zomklamo we-Absorber

(1) Isilinganiso se-calcium-sulfur akufanele sibe ngaphezu kuka-1.05.

(2) Uma usebenzisa i-demister engaphakathi kombhoshongo, ijubane legesi yomoya wokungenisa umoya ngaphansi kwezimo zomklamo akufanele lidlule u-3.8m/s, okungaqashwa yi-a Corii-olisfphansiwahlanganaer.

(3) Isakhiwo esihlanganisiwe sechibi elinodaka kanye nomzimba wombhoshongo siyathandwa.

(4) Isikhathi sokuhlala kokujikeleza kwe-slurry akufanele sibe ngaphansi kwemizuzu emi-4, kanti umbhoshongo wekholomu yoketshezi akufanele ube ngaphansi kwemizuzu emi-2.5.

(5) Indandatho yokugcina amanzi kanye nesimbozo semvula kufanele kufakwe endaweni lapho kuhlangana khona ipayipi lokungenisa amanzi eliyi-absorber kanye nodonga oluqondile lwesimbozi.

(6) Ipayipi lokungena lombhoshongo ongenalutho wesifutho kufanele lihlelwe ngendlela yokungena ebheke phansi. Lapho kwamukelwa ilungiselelo lokungena elivundlile, kufanele kuqinisekiswe ukuthi indawo ephansi kakhulu yepayipi lokungena endololwaneni yokuqala eduze kwepayipi lokungenisa imfucuza iphakeme ngamamitha ayi-1.5 kuya kwangu-2 kunezinga elijwayelekile loketshezi olusebenzayo lechibi le-absorber slurry. Ipayipi lokungena lombhoshongo wekholomu yoketshezi lingahlelwa ngendlela yokungena evundlile noma eqondile.

(7) Ibanga phakathi kwezingqimba zokufutha eziseduze zombhoshongo ongenalutho wokufutha akufanele libe ngaphansi kuka-1.8m.

(8) Ingqimba yokufafaza ephezulu yombhoshongo wokufafaza ongenalutho kufanele ifafaze iye phansi kuphela, futhi ibanga eliqondile ukusuka kungqimba ephansi kakhulu yomgqomo wokufutha akufanele libe ngaphansi kwama-2m.

(9) Emibhoshongweni yokufafaza ehlonyiswe ngamathileyi anezimbobo kanye nama-tabulator, amathileyi anezimbobo kanye nama-tabulator blades kufanele enziwe ngezinto ezilwa nokugqwala ezenziwe nge-alloy.

(10) Uma idivayisi yokushisa nokushintshanisa igesi yokukhipha umoya ingafakiwe, ukukhethwa kwamapharamitha okuklama njengesilinganiso sokugeleza kombhoshongo ongenalutho, isilinganiso segesi eliwuketshezi, kanye nokuqukethwe okuqinile kwe-slurry kwe-absorber kufanele kucabangele izidingo zokusebenza kahle kwe-desulfurization kanye nomthelela wezinto ezifana nokunciphisa inani lamaconsi egesi e-flue athwalwayo.

(11) Umklamo we-absorber kufanele uvumelane nobubanzi bomklamo womthwalo webhoyila kanye nokuqukethwe kwe-sulfur yamalahle.okungeyona eyenuzii-slurry density meterkusukelaI-LonnmeterKunconywa ukuthi kuqashwe ukuminyana kwe-limestone ne-gypsum endaweni yokuphuma ukuze kuqinisekiswe izinga elanele lokususa i-sulfur.
