Case |Yuav ua li cas siv roj-dawb ntsia hlau blowers thiab centrifugal blowers rau lub zog-txuag transformation nyob rau hauv cov cement kev lag luam?
SCR denitrification thev naus laus zis, uas yog, xaiv txoj kev txo qis qis, cov pa roj ammonia yog txau rau hauv qhov kub-kub flue roj denitrification ntaus ntawv ua tus neeg sawv cev denitrification.Nyob rau hauv qhov kev txiav txim ntawm lub catalyst, NOx nyob rau hauv cov roj flue yog decomposed rau hauv non-toxic thiab tsis muaj kuab paug N₂ thiab H₂O.Nyob rau hauv kev khiav hauj lwm boiler SCR ntaus ntawv, tus denitrification tus nqi nce mus txog 80-90%, thiab cov ammonia khiav yog qis dua 3 mg / Nm³, uas yog heev zoo raws li cov kev xav tau ntawm high denitrification efficiency ntawm cement nroj tsuag.
① Cov kua ammonia raug xa los ntawm cov kua ammonia tank tsheb mus rau cov kua ammonia cia tank los ntawm lub unloading compressor
② Tom qab evaporating mus rau hauv ammonia nyob rau hauv lub evaporation tank, nws nkag mus rau hauv lub boiler cheeb tsam los ntawm lub ammonia tsis tank thiab thauj pipeline.
③Tom qab sib xyaw ua ke nrog huab cua, nws nkag mus rau SCR reactor los ntawm kev faib cov tsav valve rau cov tshuaj tiv thaiv sab hauv.Lub SCR reactor yog ntsia rau pem hauv ntej ntawm cov cua preheater, thiab cov roj ammonia nyob saum lub SCR reactor.
④ Muab cov pa luam yeeb sib npaug los ntawm cov cuab yeej tshuaj tsuag tshwj xeeb
⑤ Tom qab sib tov, cov roj flue dhau los ntawm cov txheej txheem catalyst hauv lub reactor kom txo cov tshuaj tiv thaiv.
Cua compressor cua tshuab tshuab tshuab
Thaum xaiv cov txheej txheem soot tshuab, ntxiv rau cov hmoov tshauv tshuab, kev hnav cov nyhuv ntawm cov catalyst kuj yuav tsum tau xav txog.Tam sim no, cov txheej txheem catalyst soot tshuab feem ntau siv hauv SCR denitration systems muaj xws li sonic soot tshuab, steam soot blowing thiab compressed cua soot tshuab.
Ua ke nrog cov yam ntxwv ntawm cov cement kiln pa taws thiab plua plav, nws yog qhov nyuaj rau sonic soot blowers kom hloov mus rau qhov loj thiab siab viscosity ntawm cement kiln flue gas plua plav.Tsis tas li ntawd, cov pa roj ntau lawm hauv cov cement cog yog me me, yog li nws tsim nyog siv compressed cua los tshuab soot.
Nyob rau hauv xyoo tas los no, nrog kev txhim kho thiab kev loj hlob ntawm cov cement kev lag luam hauv kev tiv thaiv ib puag ncig, emission qauv tau nce zuj zus.Kev tiv thaiv thiab tswj cov pa phem thiab txo qis cov pa roj nitrogen oxide emissions tau dhau los ua cov haujlwm tseem ceeb uas cov tuam txhab tsim cov cement.SCR (Catalytic Reduction) thev naus laus zis muaj kev ua haujlwm siab denitrification thiab tuaj yeem ua tiav cov pa hluav taws xob tsawg ntawm cov pa roj nitrogen oxides thiab ammonia khiav tawm hauv cov xwm txheej ntawm kev noj ammonia tsawg.Nyob rau hauv xyoo tas los no, cement kiln flue gas SCR thev naus laus zis kuj tau ua tiav qee yam, muab kev lees paub zoo rau cov tuam txhab cement kom ua tiav cov pa hluav taws xob tsawg.
