Unobangela kunye namanyathelo othintelo avela kwiqondo lokushisa eliphantsi losulelo lweemveliso ze-Steam

Yintoni i-boiler ye-boiler ye-Loard I-Sormosion?

I-SulFuric Acid I-Acid yoNgcali enzeka kumhlaba wokufudumeza umva we-boiler (i-Area Arheezer, i-Preheizer yomoya) ibizwa ngokuba yi-Prosion ye-Floue Sokhima kwicandelo le-Sheue kwicandelo le-fube lokufudumeza liphantsi. Emva kokuba iqondo lobushushu eliphantsi lenzeka kwi-the Economizer Tube, ukuvuza inokwenzeka ngexesha elifutshane, libeka emngciphekweni wokhuseleko. Ukuvala phantsi iziko lolungiso kuya kubangela ilahleko enkulu yezoqoqosho.

Eyona nto iphambili yokufumana ubushushu obuphantsi

I-sulfure kwi-piopur itshiswe ukuba yenze i-sulfure diokside (s + 02 = sho2). I-sulfur diokside iphinda iqhubeke iphantsi kwesenzo se-catalyst ukuba yenze i-sulfuur trioxide (2SO22 + 02 = 2s03). I-SO3 kunye ne-vapor yamanzi kwi-flie yegesi ivelisa i-valfuric vid vapor (TO3 + H2O = h2O4). Ubukho be-sulfuric vid vapor vapor inyuka kakhulu igesi yeflethi. Since the air temperature in the air preheater is low, the flue gas temperature in the preheater section is not high, and the wall temperature is often lower than the flue gas dew point. Ngale ndlela, i-Sulfuric Acid Vapor iya kulifumana kumphezulu wokufudumeza wamabhanti omoya, ibangela i-sulfuric syrrosion. I-Inrosion yeqondo lobushushu idla ngokuvela kwi-Pretheaters yomoya, kodwa xa umxholo wesalfure kwi-sulfure uvukile, kwaye i-sub ye-ofisi ye-oid iphantsi, i-tudid dew i-tube inokubandezeleka.

I-boiler iphantsi kweqondo lobushushu

Ukujikeleza kwenkampani yokujikeleza kwe-fluhidity ye-fluhidity ye-fluhidity ye-fluhidity yenziwa rhoqo ngonyaka kangangexesha elingaphantsi konyaka, kwaye imibhobho emininzi kwi-pipe yoqoqosho esezantsi yabangelwa kukungaziphathi kakuhle kunye nokuvuza. I-Boiler ipetroli ngumxube wamalahle amnyama kunye ne-sludge, i-subluzezez ye-tube (GB / T 30877-2008), kwaye i-Ekrizezezize i-Itlet iphantsi kwe-100 ° C.

Izizathu zokuvuza kunye nokuvuza kwe-tube yezoqoqosho zahlalutywa ngohlalutyo lwepropathi yezinto ezibonakalayo, i-villation ye-roctrong, njl. Udonga lwangaphandle lwe-sub yeqonga lezakhono luhlupheka kubushushu obuphantsi phantsi kwendlela yobushushu obuphantsi kunye nokuntywila kwe-acid ngexesha lokuvalwa, nto leyo ekhokelela ekuthinjweni. Umbhobho wawuphileka, wathwaxwa kwaye uyavuza.

Amaqondo obushushu asezantsi othintelo lothintelo
1. Yandisa iqondo lobushushu lodonga le-cube yangaphambi komoya ukuze amaqondo obushushu aphezulu aphezulu kune-Floue Dew Dew.
I-2. Yongeza i-Adjetives kwirhasi yeflue ukuze uxhase i-SO3 kwaye uthintele isizukulwane somphunga wesalfuric acid vapor. 3. Sebenzisa izixhobo zeqondo lokunganyangeki kweqondo lokunganyangeki zenze amaxhoba kunye nabahlali.
I-4. Sebenzisa i-exybun ye-oxygen ephantsi ukunciphisa ioksijini egqithisileyo kwirhasi yeflue kwaye kuthintele kwaye unciphise ukuguqulwa kwe-7 ukuya kuthi ga kwi-SE2.
5. Ngokuchonga iqondo lobushushu be-Acid Deaw, i-Acid Dew Points phantsi kweemeko ezithile zinokwaziwa ngokuchanekileyo, ngaloo ndlela ihlengahlengise amaqondo obushushu egesi ukufezekisa ezona meko zininzi ze-boiler.
