Ukuphucula ukukhuselwa kokusiNgqongileyo: Ukukhulula amandla eNkqubo yokuThuthwa kweGesi eDynamic

umfanekiso 1Desulfurization Tower

I inkqubo yokukhupha igesi desulfurization sisixhobo esibalulekileyo esisetyenziselwa ukunciphisa umxholo we-sulphur dioxide (SO2) kwi-flue gas. Umgaqo wayo wokusebenza kunye noluhlu lwesicelo lubanzi.

Oku kulandelayo yintshayelelo eneenkcukacha yokukhupha Ukuchithwa kwegesi inkqubo:

1.Umgaqo wokuSebenza

Umgaqo wokusebenza we-exhaust gas desulfurization system yahlulwe kakhulu kwi-desulfurization emanzi kunye ne-desulfurization eyomileyo:

umfanekiso 2 Itshathi equkuqelayo yenkqubo yokukhupha irhasi desulfurization

I-desulfurization emanzi:I-Desulfurization emanzi yenye yezona teknoloji zisetyenziswa kakhulu kwi-desulfurization. Kwinkqubo ye-desulfurization emanzi, izisombululo ze-alkaline ezifana ne-limestone slurry okanye i-sodium hydroxide zidla ngokusetyenziswa njenge-absorbents. Xa igesi ye-flue idlula kwinqaba ye-desulfurization, idibene ngokupheleleyo nenkungu yamanzi okanye isisombululo se-alkaline esitshizwe kwi-spray layer. Isulphur dioxide ekwigesi yomkhuhlane ifunxwa sisifunxi kwaye ichaphazeleke ngokwekhemikhali yenze iisulfates (ezifana necalcium sulfite okanye icalcium sulfate). Emva koko, ezi sulfates zinokuphinda ziqhubekeke, ezifana ne-oxidation, icrystallization, njl., ukwenza iimveliso eziphumayo ezifana negypsum.

I-Dry desulfurization:I-Desulfurization eyomileyo ayisebenzisi amanzi okanye isisombululo, kodwa isebenzisa i-absorbents eyomileyo (efana ne-activated carbon, i-calcium oxide, njl.) ukuze ifake i-sulfur dioxide kwi-flue gas. Le ndlela idla ngokufanelekileyo kwiimeko apho umthamo wamanzi kwi-flue gas uphantsi okanye amanzi amdaka kufuneka agwenywe.

2.Ukwakheka kwenkqubo

Inkqubo yokuchithwa kwerhasi yenkunkuma idla ngokubandakanya ezi ndawo zilandelayo:

Inkqubo yerhasi yomkhuhlane: Yenziwe ngocango lwesidambisi shushu segesi engeneyo, ucango lwesidambisi shushu segesi ephumayo, umlunjana wentsimbi, njl.

Inkqubo yokulungiselela ukufunxa (indlela emanzi): Okufana nenkqubo yokulungisa uludaka lwelimestone, kubandakanywa isisele somgubo welimestone, ihopha engcangcazelayo, izixhobo zokuweyisha, i-screw feeder, umatshini wokulungiselela uludaka, njl.

Inqaba ye-Desulfurization: Inqaba ye-desulfurization sisixhobo esisisiseko senkqubo ye-desulfurization. Irhasi ye-flue iphendula ngokwekhemikhali kunye ne-absorbent kwinqaba ukufezekisa umphumo we-desulfurization. Inqaba ye-desulfurization emanzi idla ngokuxhotyiswa ngomaleko wokutshiza kunye nomaleko wokupakisha ukuphucula ukusebenza kakuhle kwe-desulfurization.

Umfanekiso we-9 Inqaba yesulfurization

Inkqubo yeGypsum dehydration (indlela emanzi):Kwiimveliso zemveliso ezifana ne-gypsum eveliswa yi-desulfurization emanzi, unyango lwe-dehydration luyafuneka ekusebenziseni okanye ukulahlwa okulandelayo.

Inkqubo yobunjineli boluntu: Kubandakanya inkqubo yamanzi, inkqubo yokusabalalisa amandla aphantsi-i-voltage kunye nenkqubo yomoya ecinezelekileyo, njl., Ukubonelela ngeemeko zokusebenza eziyimfuneko kwinkqubo ye-desulfurization.

Inkqubo eQhubekayo yokuHlolwa kweGesi yoMbane (CEMS):esetyenziselwa ukulinganisa iiparamitha zegesi ye-flue yesixhobo se-desulfurization ngexesha langempela, ukubonelela ngedatha yokulungelelanisa iiparitha zokusebenza zesixhobo se-desulfurization, ukuqinisekisa ukusebenza okuqhelekileyo kwesixhobo, kunye nokubonelela ngedatha yokuvavanya ukusebenza kwesixhobo se-desulfurization.

3.Umda wosetyenziso

I inkqubo yokukhupha igesi desulfurization isetyenziswa ngokubanzi kwiinkalo zoshishino ezahlukeneyo, ingakumbi ezo mizi-mveliso ezifuna isixa esikhulu reactions imichiza kunye nokuvelisa irhasi flue equlathe sulfur dioxide, ezifana petrochemicals, ukucokisa ioli, metallurgy, izichumisi imichiza, intsimbi, umbane, njl.

4.Izinto eziluncedo kwezobuGcisa

I inkqubo yokukhupha igesi desulfurization ineenzuzo ezininzi zobugcisa, kubandakanywa ukusebenza kakuhle kwe-desulfurization, imo yokusebenza eguquguqukayo, ukusetyenziswa okubanzi, kunye neemveliso eziphumayo ezihambelana nokusingqongileyo. Ukongeza, kunye nokuqhubela phambili kweteknoloji, inkqubo ye-gas desulfurization yenkunkuma ihlala iphuculwa kwaye iphuculwe ukuphucula ukusebenza kwe-desulfurization, ukunciphisa iindleko zokusebenza kunye nokunciphisa impembelelo yokusingqongileyo.

5. Isishwankathelo

umfanekiso 10 Inkunkuma yegesi desulfurization izixhobo

Isishwankathelo, inkqubo ye-gas desulfurization yinkqubo ebalulekileyo yokukhusela indalo, eyona nto ibaluleke kakhulu ekunciphiseni umxholo wesulfure dioxide ekukhutshweni kwamashishini kunye nokukhusela okusingqongileyo kunye nempilo yabantu.
