Izimbangela nezindlela zokuvimbela zokugqwala okushisa okuphansi kwama-generator aphansi

Yini ukugqwala okushisa okuphansi okuphansi?

Ukugqwala kwe-Sulfuric Acid okwenzeka ebusweni bokushisa emuva kwe-boiler (economizer, i-air Presemute) ibizwa ngokuthi ukugqwala okushisa okuphansi ngoba amazinga okushisa e-tube odongeni esigabeni ngemuva kokushisa komhlaba aphansi. Ngemuva kokugqwala okushisa okuphansi kwenzeka ku-economizer tube, ukuvuza kungavela esikhathini esifushane, kubeka izingozi zokuphepha. Ukuvala isithando somlilo sokulungiswa kuzodala ukulahleka komnotho okukhulu.

Imbangela enkulu yokugqwala okushisa okuphansi kwama-boilers

Isibabule kuphethiloli sishiswe ukuze sakha i-sulphur dioxide (S + 02 = so2). I-sulphur dioxide iqhutshwa njalo ngaphansi kwesenzo se-catalyst ukwakha i-sulfur trioxide (2SO2 + 02 = 2S03). Ngakho-ke kanye nomphunga wamanzi kugesi we-flue akhiqiza umphunga we-sulfuric acid (SO3 + H2O = H2SO4). Ukuba khona kwe-Sulfuric Acid Vapor kukhulisa kakhulu iphuzu le-DEW yegesi. Kusukela izinga lokushisa lomoya endaweni yokufa komoya liphansi, izinga lokushisa legesi esigabeni se-Prehall Ngale ndlela, umphunga we-sulfuric acid uzokulahla endaweni yokufudumeza ye-air prebeter, ebangela ukugqwala kwe-sulfuric acid. Ukugqwala okushisa okuphansi kuvame ukwenzeka kuma-air preheaters, kepha lapho okuqukethwe se-sulfur kuphethiloli kuphezulu, okuqukethwe kwe-soud ngokweqile kukhuphuka kakhulu, i-turbine yamaphuzu ikhuphuka ekushiseni okuphezulu), ishubhu le-economizer lingahle liphethwe ngokushiswa kwamazinga okushisa aphansi.

Icala lokushaya okuphansi lokushisa okuphansi

I-boiling yombhede ejikelezayo yenkampani yafakwa ekusebenzeni njalo esikhathini esingaphansi konyaka, kanti amapayipi amaningi epayipi eliphansi lezondlamnotho ahlushwa ama-perforations kanye nokuvuza. I-boiler uphethiloli iyingxube yamalahle we-butuminous kanye ne-sludge, i-economizer tube impahla iyinsimbi engama-20 (GB / T 3087-2008), futhi izinga lokushisa le-economizer inlet livame ukwedlula i-100 ° C.

Izizathu ze-bheruna nokuvuza kweshubhu le-economizer kuhlaziywe ngokuhlaziywa kokwakheka kwezinto ezibonakalayo, ukuhlolwa kwempahla okwenziwe ngomshini, ukuhlaziywa kwe-elektroni Microscope morphology, futhi imikhiqizo yokuphazamiseka ye-electron, futhi imikhiqizo yokugqwala iqukethe izinto eziningi ze-s kanye nama-Cl. Udonga lwangaphandle lweshubhu le-economizer luhlushwa ukugqwala okuphansi ngaphansi kokusebenza okuphansi kokushisa kanye nokugqwala kwe-acid ngesikhathi sokuvalwa, ekugcineni okuholela ekusindisweni kwamalahle. Ipayipi liyagcwala, ligcwele futhi livuza.

Izindlela Zokuvimbela Ukuvimbela Ukuvulwa Okuphansi
1. Khulisa izinga lokushisa lodonga lwe-air prebeter tube ukuze izinga lokushisa lodonga liphakeme kunephuzu le-flue dew dew.
2. Faka izithasiselo kugesi we-flue ukuze ukhubazeke ukuze uvike ukuze uvikele ukukhiqizwa kwe-sulfuric acid vapor. 3. Sebenzisa izinto ezingamelana ne-corosion ezingavinjelwe okuphansi ukwenza izinto zokuzenzisa nomoya.
4. Sebenzisa ukuhlanganiswa okuphansi kwe-oxygen ukunciphisa umoya-mpilo ngokweqile kugesi ye-flue futhi uvikele futhi wehlise ukuguqulwa kwe-SO2 ku-so0.
