Ukuthuthukisa Ukuvikelwa Kwemvelo: Ukukhulula Amandla Ezinhlelo Zokuqeda Igesi Ephuma Kakhulu

isithombe 1I-Desulfurization Tower

I i-exhaust gas desulfurization system iyithuluzi elibalulekile elisetshenziselwa ukwehlisa i-sulphur dioxide (SO2) okuqukethwe kwe-flue gas. Isimiso sayo sokusebenza kanye nebanga lohlelo lokusebenza libanzi.

Okulandelayo yisingeniso esiningiliziwe se-exhaust I-Gas Desulfurization uhlelo:

1.Isimiso sokusebenza

Umgomo wokusebenza wesistimu ye-exhaust gas desulfurization ihlukaniswe ikakhulukazi i-desulfurization emanzi kanye ne-desulfurization eyomile:

isithombe 2 Ishadi eligelezayo lesistimu ye-exhaust gas desulfurization

I-Desulfurization emanzi:I-Desulfurization emanzi ingenye yobuchwepheshe obusetshenziswa kakhulu be-desulfurization. Enqubweni ye-desulfurization emanzi, izixazululo ze-alkaline ezifana ne-limestone slurry noma i-sodium hydroxide ngokuvamile zisetshenziswa njengama-absorbents. Lapho i-flue gas idlula embhoshongweni we-desulfurization, ithintwa ngokuphelele nenkungu yamanzi noma isisombululo se-alkaline esifuthwe kusukela kungqimba lwesifutho. I-sulphur dioxide ku-flue gas imunca into emunca futhi isabela ngamakhemikhali ukwenza ama-sulfate (njenge-calcium sulfite noma i-calcium sulfate). Kamuva, lawa ma-sulfate angase aphinde acutshungulwe, njenge-oxidation, i-crystallization, njll., ukuze kwakheke imikhiqizo efana ne-gypsum.

isithombe 8 Umdwebo wesakhiwo sombhoshongo we-Desulfurization

I-Dry desulfurization:I-Desulfurization eyomile ayisebenzisi amanzi noma isixazululo, kodwa isebenzisa izinto ezimunca okomile (njenge-activated carbon, calcium oxide, njll.) ukuze ifake i-sulphur dioxide kugesi we-flue. Le ndlela ivamise ukufaneleka ezikhathini lapho umthamo wamanzi kugesi we-flue uphansi noma amanzi angcolile kudingeka agwenywe.

2.Ukwakheka kwesistimu

Uhlelo lwe-desulfurization gas desulfurization ngokuvamile luhlanganisa izingxenye eziyinhloko ezilandelayo:

Isistimu yegesi yomkhuhlane: Yakhiwe ngomnyango we-inlet flue gas damper door, bypass flue gas damper door, iron flue, njll., enesibopho sokwethula igesi ewuflue equkethe i-sulphur dioxide ohlelweni lwe-desulfurization.

Isistimu yokulungiselela i-Absorbent (indlela emanzi): Okufana nesistimu yokulungisa udaka lwe-limestone, okuhlanganisa isisele sempushana ye-limestone, i-hopper edlidlizayo, okokusebenza kwesisindo, isifunzo sesikulufu, umshini wokulungisa udaka, njll., okusetshenziselwa ukulungisa okokumunca okudingekayo ukuze kukhishwe i-sulfurization.

Umbhoshongo we-Desulfurization: Umbhoshongo we-desulfurization uyisisekelo sesistimu ye-desulfurization. I-flue gas iphendula ngamakhemikhali nokumunca embhoshongweni ukuze kuzuzwe umphumela we-desulfurization. Umbhoshongo omanzi we-desulfurization ngokuvamile ufakwe isendlalelo sesifutho kanye nesendlalelo sokupakisha ukuthuthukisa ukusebenza kahle kwe-desulfurization.

isithombe 9 Umbhoshongo we-Desulfurization

I-Gypsum dehydration system (indlela emanzi):Emikhiqizweni efana ne-gypsum ekhiqizwe i-desulfurization emanzi, ukwelashwa kokuphelelwa amanzi emzimbeni kuyadingeka ukuze kusetshenziswe noma ukulahlwa okulandelayo.

Uhlelo lobunjiniyela bomphakathi: Kubandakanya uhlelo lwamanzi enqubo, isistimu yokusabalalisa amandla aphansi-voltage kanye nesistimu yomoya ecindezelwe, njll., ukuhlinzeka ngezimo zokusebenza ezidingekayo zesistimu ye-desulfurization.

Uhlelo Oluqhubekayo Lokuqapha Ukuphuma Kwegesi Yomkhuhlane (CEMS):esetshenziselwa ukukala imingcele yegesi ye-flue yedivayisi ye-desulfurization ngesikhathi sangempela, inikeze idatha yokulungisa imingcele yokusebenza yedivayisi ye-desulfurization, iqinisekise ukusebenza okuvamile kwedivayisi, futhi inikeze idatha yokuhlolwa kokusebenza kwedivayisi ye-desulfurization.

3.Ububanzi besicelo

I i-exhaust gas desulfurization system isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni, ikakhulukazi lezo zimboni ezidinga inani elikhulu lokusabela kwamakhemikhali futhi zikhiqize igesi ye-flue equkethe i-sulphur dioxide, njengamakhemikhali e-petrochemicals, ukucwenga uwoyela, i-metallurgy, umanyolo wamakhemikhali, insimbi, ugesi, njll.

Izinzuzo 4.Technical

I i-exhaust gas desulfurization system inezinzuzo eziningi zobuchwepheshe, okuhlanganisa ukusebenza kahle kwe-desulfurization ephezulu, imodi yokusebenza eguquguqukayo, ukusebenziseka okubanzi, kanye nemikhiqizo ephuma eceleni evumelana nemvelo. Ukwengeza, ngokuthuthuka okuqhubekayo kobuchwepheshe, uhlelo lwegesi engcolile ye-desulfurization luhlala luthuthukiswa futhi luthuthukiswa ukuze kuthuthukiswe ukusebenza kahle kwe-desulfurization, ukunciphisa izindleko zokusebenza kanye nokunciphisa umthelela wemvelo.

isithombe 10 Imishini yokususa igesi engcolile

Kafushane, uhlelo lokususa igesi engcolile luyithuluzi elibalulekile lokuvikela imvelo, elibaluleke kakhulu ekunciphiseni okuqukethwe yi-sulphur dioxide ekukhishweni kwezimboni kanye nokuvikela imvelo nempilo yabantu.
