SCR Soot Blower

SCR soot tshuab tshuab yog ib qho tseem ceeb ntawm Selective Catalytic Reduction (SCR) denitrification technology. SCR thev naus laus zis yog ib qho ntawm cov cuab yeej siv hluav taws xob ntau tshaj plaws, feem ntau yog siv los txo nitrogen oxide (NOx) emissions generated hauv cov txheej txheem kev lag luam. Hauv SCR system, cov roj flue ua ntej dhau los ntawm lub txaj catalyst. Nyob rau hauv qhov kev txiav txim ntawm cov catalyst, ammonia los yog urea ua raws li tus neeg sawv cev txo kom txo NOx rau hauv nitrogen (N2) thiab dej vapor (H2O). Txawm li cas los xij, thaum lub sijhawm ua haujlwm no, lub txaj catalyst tuaj yeem khaws cov plua plav thiab lwm yam impurities, uas yuav txo qis cov haujlwm ntawm catalyst thiab cuam tshuam rau kev ua haujlwm denitrification. Yog li ntawd, lub luag haujlwm ntawm SCR soot tshuab yog ua kom huv si tsis tu ncua cov tshauv ntawm lub txaj catalyst kom tswj tau lub xeev ua haujlwm zoo ntawm cov catalyst.

SCR denitrification reactor soot blower tuaj yeem siv los tshem tawm cov plua plav tawm ntawm lub reactor inlet thiab qhov hluav taws xob, catalyst nto lossis sab hauv steel tivthaiv nto, ncua kev ua haujlwm thiab kev pab cuam lub neej ntawm cov catalyst hauv SCR, thaum txo cov kev ua haujlwm siab hauv lub cev, tshem tawm. Qhov cuam tshuam ntawm kev hloov pauv ntau dhau ntawm cov hmoov tshauv ya mus rau cov khoom siv plua plav tom ntej, thiab txo cov neeg ua haujlwm txhua xyoo thiab cov nqi khoom siv, ua kom lub sijhawm ua haujlwm luv luv, thiab txuas ntxiv lub sijhawm ua haujlwm boiler.

SCR sootblowing system feem ntau suav nrog sootblower thiab sootblower kiv cua. Sootblower tuaj yeem ua ntau hom xws li sonic sootblower, chav sootblower lossis compressed cua sootblower. Cov sootblower tuaj yeem xa cov cua kub ceev lossis cov pa mus rau lub txaj catalyst kom tshem tawm cov khib nyiab los ntawm cov catalyst nto thiab nqa nws tawm ntawm cov pa roj.

SCR sootblowing system yog dav siv nyob rau hauv ntau yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv thermal fais fab nroj tsuag, cement nroj tsuag thiab khib nyiab incineration nroj tsuag uas muaj ntau ntawm NOx emissions generated. Piv txwv li, nyob rau hauv SCR denitration transformation ntawm cement kilns, vim muaj ntau ntawm alkaline ntiaj teb hlau CaO nyob rau hauv lub flue roj, nws yog ib qho yooj yim mus tsim tshauv bridging thiab blockage ntawm lub catalyst nto, accelerating lub hnav thiab lom. lub catalyst. Yog li ntawd, kev teeb tsa ib txoj hauv kev zoo sootblowing yog tus yuam sij kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov ntawm SCR denitration system.

Lub ntsiab tam sim no SCR denitration tu txheej txheem yog sonic sootblower, chav sootblower thiab sonic + chav sootblower. Tam sim no, cov txheej txheem tu sonic sootblower feem ntau yog siv rau cov boilers me thiab nruab nrab. Feem ntau ntawm cov chav nyob saum 200MW siv sonic + chav sootblower. Qee qhov kev lag luam tshwj xeeb, xws li iav qhov cub nrog cov hmoov tshauv viscosity siab hauv cov pa roj, tsuas yog siv cov tshuab sootblower.
