II. IiNdawo ezintathu eziSebenzayo zeDesulfurization Absorber

I-absorber inokwahlulwa ibe yimimandla emithathu esebenzayo ukusuka phezulu ukuya ngasezantsi: i-oxidation crystallization, i-absorption kunye ne-demisting zone.

(1) Indawo yecrystallization ye-oxidation ibhekiselele kwidama eliludaka lwesixhobo sokufunxa, kwaye umsebenzi walo ophambili kukunyibilikisa i-limestone kunye ne-oxidize calcium sulfite.

(2) Indawo yokufunxa ibandakanya indawo yokufunxa, itreyi kunye nemigangatho emininzi yezitshizi. Kukho imilomo yekhowuni emininzi enomgongxo kumaleko ngamnye wesixhobo sokutshiza; umsebenzi ophambili we-absorber uxhomekeke kungcoliseko lwe-acidic kunye nokufunxa uthuthu kwigesi yomkhuhlane.

(3) Indawo yokulahla inezigaba ezibini zokulahla ngaphezulu komgangatho wokutshiza. Umsebenzi wayo oyintloko kukuhlula amaconsi kwi-flue gas, ukunciphisa impembelelo kwisixhobo esisezantsi kunye ne-dosage of absorbent.

Indawo yokufunxa ye-absorption ibhekisa kwindawo ephakathi komgca osembindini we-inlet ye-absorption kunye neyona ndawo iphezulu yokutshiza. Udaka olutshiziweyo luhlamba irhasi yeflue enesulfure kule ndawo. Ukuphakama okwaneleyo kwendawo yokufunxa kuqinisekisa izinga eliphezulu le-desulfurization. Ukuphakama komphakamo, kokukhona kusezantsi umyinge wokuqukuqela kwempompo ejikelezayo efunekayo Ngaphantsi kwemfuno efanayo kwireyithi ye-desulfurization.

Indawo yokutshiza ye-absorber ichazwa ngolu hlobo:

(1) Inqaba yokutshiza: yi-1.5m ngaphantsi kowona mlomo uphantsi ukuya kwindawo yokuphuma kowona mlomo uphakamileyo.

(2) Intsika yentsika yolwelo: ukusuka kwindawo yokuphuma kowona mlomo uphantsi ukuya kwi-0.5m ngaphezu kwekholamu yolwelo iphezulu xa zonke iimpompo zokujikeleza kodaka zisebenza.

I-absorber sisixhobo esisisiseko se-flue gas desulfurization system. Ifuna indawo enkulu yokudibanisa i-gas-liquid, ukusabela okulungileyo kokufunxa igesi, ilahleko encinci yoxinzelelo. Ilungele ukunyangwa kwerhasi enomthamo omkhulu. La manyathelo enkqubo alandelayo agqityiweyo kwesi sixhobo:

① Ukufunxa iigesi ezinobungozi ekuhlambeni uludaka;

② Ukwahlulwa kwerhasi yombane kunye nodaka lokuhlamba;

③ Ukungathathi hlangothi kodaka;

④ Ukufakwa kwe-oxidation yeemveliso zokungathathi hlangothi kwigypsum;

⑤ Gypsum crystallization.

III. Ukuqulunqwa kwe-Absorber

I-absorber ihlulwe ngokubanzi ibe yi-cylinder, i-flue gas inlet kunye ne-flue gas outlet kwisakhiwo. I-flue gas inlet kunye ne-outlet ilele phakathi kwe-absorber kwaye phezulu kwe-absorber ngokuhambelana ngokuqhelekileyo. I-cylinder ye-absorber inokwahlulwa ibe yi-slurry pool, i-sprayer layer kunye ne-demisting area ekusebenzeni. I-pool ye-slurry ifumaneka kwindawo esezantsi ye-absorber inlet ngokubanzi, kwaye i-spray layer kunye ne-demister ifumaneka phakathi kwe-flue gas inlet kunye ne-outlet. I-flue gas outlet ye-absorber ingaba yindawo ephezulu ephezulu okanye i-horizontal side outlet.

Indawo yesiqhelo yokutshiza ibonakalisa umaleko wokutshiza kunye nemilomo kunye nezinye izixhobo. Ngokuxhomekeke kwinkqubo ye-desulfurization, indawo yokutshiza yezinye i-absorbers nazo ziya kuxhotyiswa ngeetreyi, iintonga ze-Venturi kunye nezinye izixhobo.

IV. Iimfuno zoyilo ze-Absorber

(1) Umlinganiselo we-calcium-sulfur akufanele ube mkhulu kune-1.05.

(2) Xa usebenzisa i-demister ye-in-tower, isantya serhasi yeflue phantsi kweemeko zoyilo kufuneka singagqithi kwi-3.8m/s, esinokubekwa iliso Coriiolisfphantsiwadibanaer.

(3) Ulwakhiwo oludityanisiweyo lwedama lodaka kunye nomzimba wenqaba lukhethwayo.

(4) Ixesha lokuhlala lokujikeleza kwe-slurry akufanele libe ngaphantsi kwe-4 min, kunye nenqaba yekholomu yolwelo kufuneka ingabi ngaphantsi kwe-2.5 min.

(5) Iringi yogcino lwamanzi kunye nesigqubuthelo semvula kufuneka zifakwe ekudibaneni kombhobho wokungenisa amanzi kunye nodonga oluthe nkqo lwesibambisi.

(6) Umbhobho wokungena wesitshizi ongenanto kufuneka ucwangciswe ngendlela yokungena e-oblique ezantsi. Xa ulungelelwaniso lokungena oluthe tye lwamkelwa, kufuneka kuqinisekiswe ukuba indawo esezantsi yeflue kwingqiniba yokuqala kufuphi ne-absorbent inlet yi-1.5 ukuya kwi-2m ephezulu kunomgangatho oqhelekileyo wokusebenza we-absorber slurry pool. I-inlet flue ye-liquid column tower inokulungiswa ngendlela ethe tye okanye ethe nkqo yokungena.

(7) Umgama phakathi kweeleya zokutshiza ezimeleneyo zesitshizi senqaba engenanto kufuneka ungabi ngaphantsi kwe-1.8m.

(8) Umaleko ongaphezulu wokutshiza wenqaba yokutshiza engenanto kufuneka utshize ujonge ezantsi kuphela, kwaye umgama womnatha ukusuka kowona maleko uphantsi we-demister kufuneka ungabi ngaphantsi kwe-2m.

(9) Kwiinqaba zokutshiza ezixhotyiswe ngeetreyi ezirhabaxa kunye neetabulayitha, iitreyi ezirhabaxa kunye neeblade zetabulator kufuneka zenziwe ngealloy anti-corrosion materials.

(10) Xa igesi yokukhupha igesi yokufudumeza kunye nesixhobo sotshintshiselwano lobushushu singafakwanga, ukhetho lweparamitha zoyilo ezifana nesantya sokuhamba kwenqaba engenanto, umlinganiselo werhasi engamanzi, kunye nodaka oluqinileyo lwesiqulatho sokufunxa kufuneka kuthathelwe ingqalelo iimfuno zempumelelo ye-desulfurization kunye nefuthe lezinto ezinjengokunciphisa ubungakanani bamathontsi erhasi ye-net flue.

(11) Uyilo lwesibambisi kufuneka lulungelelaniswe kuluhlu loyilo lomthwalo webhoyila kunye nomxholo wesalfure yamalahle. Umntu okrelekreleengeyonyukliyai-slurry density meterukusukaLonnmeterKucetyiswa ukuba kujongwe ukuxinana kwe-limestone kunye negypsum kwindawo yokuthengisa ukuze kuqinisekiswe izinga elaneleyo le-desulfurization.
