Isifunxi se-Desulfurization

II. Iindawo Ezintathu Ezisebenzayo ze-Desulfurization Absorber

I-absorber inokwahlulwa ibe ziindawo ezintathu ezisebenzayo ukusuka phezulu ukuya ezantsi: i-oxidation crystallization, i-absorption kunye ne-demisting zone.

(1) Indawo yokwenza i-oxidation crystallization ibhekisa kwidama elimdaka le-absorber, kwaye umsebenzi walo oyintloko kukunyibilikisa i-limestone kunye ne-oxidize i-calcium sulfite.

(2) Indawo yokufunxa ibandakanya indawo yokungena ye-absorber, itreyi kunye neeleya ezininzi ze-spray. Kukho ii-nozzles ezininzi ze-hollow cone kumaleko ngamnye wesixhobo sokufunxa; umsebenzi oyintloko we-absorber kukufumana ungcoliseko olune-asidi kunye nokufunxwa kothuthu oluphuma kwi-flue gas.

(3) Indawo yokukhupha amanzi inezithinteli-manzi ezinezigaba ezibini ngaphezulu komaleko wokutshiza. Umsebenzi wayo ophambili kukwahlula amathontsi kwigesi yokukhupha amanzi, ukunciphisa impembelelo kwizixhobo ezisezantsi kunye nomthamo wokufunxa.

Indawo yokufunxa ye-absorber ibhekisa kwindawo ephakathi komgca ophakathi wokungena kwe-absorber kunye nowe-spray layer ephezulu. I-slurry etshiziweyo ihlamba i-flue gas equlethe i-sulfur kule ndawo. Ukuphakama okwaneleyo kwendawo yokufunxa kuqinisekisa isantya esiphezulu se-desulfurization. Okukhona ukuphakama kuphezulu, kokukhona isantya sokuhamba kwepompo yokujikeleza esifunekayo siphantsi. Phantsi kwemfuneko efanayo kwisantya se-desulfurization.

Indawo yokutshiza ye-absorber ichazwa ngolu hlobo:

(1) Inqaba yokutshiza: 1.5m ngaphantsi komlomo osezantsi ukuya kwindawo yokuphuma komlomo ophakamileyo.

(2) Inqaba yekholamu yolwelo: ukusuka kwindawo yokukhupha umlomo osezantsi ukuya kwi-0.5m ngaphezu kwekholamu yolwelo ephezulu xa zonke iimpompo zokujikeleza koludaka zisebenza.

I-absorber sisixhobo esiphambili senkqubo yokukhupha i-flue gas desulfurization. Ifuna indawo enkulu yokunxibelelana negesi nolwelo, impendulo elungileyo yokufunxa igesi, ukulahleka koxinzelelo oluncinci. Ifanelekile kunyango lwegesi yokukhupha amanzi amakhulu. La manyathelo aphambili alandelayo agqitywa kwesi sixhobo:

① Ukufunxwa kweegesi eziyingozi kwi-washing slurry;

② Ukwahlulwa kwegesi yolwelo kunye ne-washing slurry;

③ Ukungaguquguquki kodaka;

④ Ukufakwa kwe-oxidation yeemveliso ze-intermediate neutralization kwi-gypsum;

⑤ Ukwenziwa kwekristale yeGypsum.

III. Ukwakheka kwe-Absorber

I-absorber ngokubanzi yahlulwe yaba sisilinda, indawo yokungena yegesi ye-flue kunye nendawo yokukhupha igesi ye-flue. Indawo yokungena yegesi ye-flue kunye nendawo yokukhupha igesi ibekwe phakathi kwe-absorber naphezulu kwe-absorber ngokufanayo ngokwesiqhelo. Isilinda ye-absorber inokwahlulwa ibe yidama le-slurry, umaleko wokutshiza kunye nendawo yokukhupha igesi esebenzayo. Idama le-slurry likwinxalenye esezantsi yendawo yokungena ye-absorber ngokubanzi, kwaye umaleko wokutshiza kunye ne-demister ziphakathi kwendawo yokungena yegesi ye-flue kunye nendawo yokukhupha. Indawo yokukhupha igesi ye-flue ye-absorber ingaba yindawo yokukhupha ephezulu okanye indawo yokukhupha esecaleni ethe tye.

Indawo yokutshiza eqhelekileyo ineeleya zokutshiza kunye neempumlo kunye nezinye izixhobo. Ngokuxhomekeke kwinkqubo yokukhupha i-sulfurization, indawo yokutshiza yezinye izifunxi iya kuxhotyiswa ngeetreyi, ii-Venturi rods kunye nezinye izixhobo.

IV. Iimfuno zoyilo lwe-Absorber

(1) Umlinganiselo we-calcium-sulfur akufuneki ube ngaphezulu kwe-1.05.

(2) Xa usebenzisa isixhobo sokukhupha umbane esingaphakathi kwinqaba, isantya segesi yolwelo sesixhobo sokufunxa umbane phantsi kweemeko zoyilo akufuneki sidlule kwi-3.8m/s, esinokujongwa yi-a Coriiolisfiphantsiwadibanaer.

(3) Ulwakhiwo oludibeneyo lwedama lokudada elimdaka kunye nomzimba wenqaba luyathandwa.

(4) Ixesha lokuhlala kokujikeleza kodaka akufuneki libe ngaphantsi kwemizuzu emi-4, kwaye inqaba yekholamu yolwelo mayingabi ngaphantsi kwemizuzu emi-2.5.

(5) Indandatho yokugcina amanzi kunye nesigqubuthelo semvula kufuneka zifakwe kwindawo edibana kuyo i-absorber inlet flue kunye nodonga oluthe nkqo lwe-absorber.

(6) Umbhobho wokungena wenqaba engenanto yokutshiza kufuneka ucwangciswe ngendlela yokungena ezantsi egobile. Xa kwamkelwa ulungiselelo lokungena oluthe tye, kufuneka kuqinisekiswe ukuba indawo esezantsi yombhobho kwingqiniba yokuqala ecaleni komnyango wokungenisa umbhobho iphezulu nge-1.5 ukuya kwi-2m kunenqanaba eliqhelekileyo lolwelo olusebenzayo lwedama lokufunxa umbhobho. Umbhobho wokungena wenqaba yekholamu yolwelo unokulungiswa ngendlela yokungena ethe tye okanye ethe nkqo.

(7) Umgama phakathi kweengqimba zokutshiza ezikufutshane zenqaba engenanto yokutshiza akufuneki ube ngaphantsi kwe-1.8m.

(8) Umaleko ophezulu wokutshiza wenqaba yokutshiza engenanto kufuneka utshize uye ezantsi kuphela, kwaye umgama opheleleyo ukusuka kumaleko osezantsi we-demister akufuneki ube ngaphantsi kwe-2m.

(9) Kwiinqaba zokutshiza ezixhotyiswe ngeetreyi ezinemibhobho kunye neetabulator, iitreyi ezinemibhobho kunye neeblade zetabulator kufuneka zenziwe ngezinto ezichasene nokugqwala ze-alloy.

(10) Xa isixhobo sokufudumeza kunye nesixhobo sokutshintshiselana nobushushu segesi ephumayo singafakwanga, ukukhethwa kweeparamitha zoyilo ezifana nesantya sokuhamba kwenqaba engenanto, umlinganiselo wegesi yolwelo, kunye nomxholo oqinileyo we-absorber kufuneka kuthathelwe ingqalelo iimfuno zokusebenza kakuhle kwe-desulfurization kunye nempembelelo yezinto ezinje ngokunciphisa ubungakanani bamaconsi egesi ephumayo.

(11) Uyilo lwesixhobo sokufunxa kufuneka lulungelelaniswe noluhlu loyilo lomthwalo webhoyila kunye nomxholo wesalfure yamalahle.engeyoyenyukliyai-slurry density meterukusukaILonnmeterKucetyiswa ukuba kujongwe uxinano lwelitye lekalika kunye negypsum kwindawo yokuphuma ukuqinisekisa izinga elaneleyo lokukhupha isalfur.
