Tam sim no, kev tiv thaiv ib puag ncig siab ntawm lub tshuab ua kom sov steelmaking cog yog loj heev. Ntawm lawv, cov plua plav tshem tawm ntawm lub tshuab hluav taws xob tig lub tshuab hluav taws xob yog qhov tseem ceeb tshaj plaws, thiab nws yog ib qho tsim nyog yuav tsum ua raws li kev hloov pauv kom ua tiav cov pa hluav taws xob tsawg. Yog li ntawd, kev xaiv thiab kev siv ntawm cov khoom siv tau zoo, kev nyab xeeb thiab kev siv tsawg ntawm cov tshuab hluav taws xob desusting tau dhau los ua cov ntsiab lus tseem ceeb rau cov tuam txhab hlau thiab hlau.
Txoj kev ntub dej thiab txoj kev qhuav ntawm rotating furnace flue gas dedusting muaj lawv tus kheej zoo
Rotating furnace ntub dedusting tshuab yog abbreviated li OG. OG yog cov ntawv luv ntawm Oxygen rotating furnace Gas Recovery hauv lus Askiv, uas txhais tau tias oxygen rotating furnace gas recovery. Lub tshuab hluav taws xob tig siv OG thev naus laus zis ua rau muaj qhov kub thiab txias thiab siab-concentration CO flue gas nyob rau hauv lub cub tawg vim muaj kev kub ntxhov oxidation thaum tshuab. Cov pa roj flue suppresses kev nkag mus ntawm cov huab cua ib puag ncig los ntawm kev nqa ntawm daim tiab thiab kev tswj hwm ntawm flue gas siab hauv lub hood. Nyob rau hauv cov ntaub ntawv ntawm unburned, lub tshuab txais lub vaporization txias flue kom txias cov flue gas, thiab tom qab tau purified los ntawm ob-theem Venturi raj plua plav collector, nws nkag mus rau hauv cov pa rov qab thiab tso system.
Rotating furnace qhuav plua plav tshem tawm tshuab yog abbreviated liLT. CovLTtxoj kev tau koom ua ke tsim los ntawm Lurgi thiab Thyssen hauv lub teb chaws Yelemees.LTyog cov ntawv luv ntawm cov npe ntawm ob lub tuam txhab. Cov tshuab no siv lub tshuab ua kom txias txias kom txias flue roj, thiab tom qab tau ntxuav los ntawm cylindrical qhuav electrostatic precipitator, nws nkag mus rau cov roj rov qab thiab tso tawm. Txoj cai no tau pib siv rau hauv cov phiaj xwm roj rov qab rau xyoo 1981.
Rotating furnace qhuav dedusting tshuab muaj ib tug loj ib zaug peev, complex qauv, ntau consumables, thiab siab technical nyuaj. Kev lag luam nce qib hauv kuv lub teb chaws yog tsawg dua 20%. Tsis tas li ntawd, cov tshuab tshem tawm cov plua plav qhuav siv lub tshuab ziab khaub ncaws loj loj kom tshem tawm cov plua plav tawm hauv qhov cub. Cov plua plav collector yog ib qho yooj yim rau cov plua plav thiab cov plua plav tawm tsis ruaj khov.
Piv nrog rau cov txheej txheem tshem tawm cov plua plav qhuav, OG ntub plua plav tshem tawm txheej txheem muaj cov qauv yooj yim, tus nqi qis, thiab kev ua kom huv huv siab, tab sis nws muaj qhov tsis zoo xws li kev siv hluav taws xob ntau, kev siv dej loj, kev kho dej phwj nyuaj, thiab cov nqi khiav lag luam siab. Tsis tas li ntawd, lub tshuab nqus plua plav ntub dej ntxuav tag nrho cov plua plav mus rau hauv dej tsis hais qhov loj me me, ua rau muaj ntau cov plua plav tshem tawm cov dej phwj tuaj. Txawm hais tias cov txheej txheem ntawm cov txheej txheem qhuav thiab ntub dej ntub dej tau raug txhim kho tsis tu ncua hauv cov txheej txheem hauv zos, lawv cov kev tsis sib haum xeeb tsis tau raug daws.
Hauv kev teb rau cov xwm txheej saum toj no, cov kws tshaj lij kev lag luam tau npaj cov tshuab nqus plua plav tawm ib nrab qhuav hauv xyoo tsis ntev los no, uas tau tshaj tawm hauv Suav teb. Tam sim no, tus naj npawb ntawm cov tshuab ua kom sov siv cov tshuab ziab khaub ncaws semi-dub tshaj li cov tshuab tig rauv siv tshuab ziab khaub ncaws qhuav. Cov txheej txheem semi-qhuav desusting siv lub evaporative txias txias kom rov qab 20% -25% ntawm cov tshauv qhuav, uas khaws cov txiaj ntsig ntawm kev ntub dej ntub dej thiab kov yeej qhov tsis xws ntawm cov tshuab ziab khaub ncaws ntub thiab ntub dej. Tshwj xeeb, cov cuab yeej no tuaj yeem hloov cov txheej txheem ntub dej ntub dej yam tsis tas yuav rhuav tshem tag nrho thiab rov ua dua nws zoo li cov txheej txheem dusting qhuav, kom cov chaw qub tuaj yeem khaws cia rau qhov loj tshaj plaws thiab cov nqi peev nyiaj tau txais kev cawmdim.
