Common Flue Gas Denitration Technologies: Ib qho luv luv piav qhia
Rau cov thawj coj ntawm cov nroj tsuag thiab cov engineers nrhiav kev tswj cov emissions, nkag siab txog cov khoom siv hluav taws xob muaj hluav taws xob yog thawj kauj ruam mus rau kev ua raws cai thiab kev ua haujlwm zoo. Cias muab, desulfurization tshem tawm sulfur dioxide (SO₂), thaum denitration tshem tawm nitrogen oxides (NOx) los ntawm boiler flue gas. Lub hauv paus ntsiab lus tseem ceeb suav nrog txo cov khoom tsim tawm NOx rov qab mus rau qhov tsis muaj nitrogen (N₂).
Ntawm no, peb piav qhia luv luv txog peb txoj kev siv thev naus laus zis, nrog rau kev tsom mus rau txoj kev siv dav tshaj plaws uas Pingxiang Zhongci Environmental Ceramics Material Co., Ltd., uas yog cov chaw tsim khoom, muab cov khoom tseem ceeb.
1. Selective Catalytic Reduction (SCR): Cov Qauv Kev Lag Luam
SCR yog qhov tshaj tawm thiab ua tau zoo tshaj plaws -combustion NOx tswj tshuab. Nws siv ammonia lossis urea los ua tus neeg sawv cev txo qis los xaiv hloov NOx rau hauv N₂ thiab H₂O dhau lub catalyst.
Vim li cas nws thiaj nyiam: Rau cov thee- cov chaw tsim hluav taws xob hluav taws xob thiab kev lag luam hnyav, SCR muaj kev tshem tawm siab (feem ntau tshaj 90%) thiab kev ntseeg tau.
Lub plawv ntawm lub system: Catalyst. Kev ua tau zoo nyob ntawm qhov tseem ceeb ntawm cov catalyst. Peb cov kws tshaj lij nyob hauv kev tsim khoom siab -kev ua tau zoo honeycomb- hom SCR catalysts, uas yog tus thawj coj ntawm kev lag luam vim lawv qhov chaw siab thiab ua haujlwm ntev.
kawm paub ntau ntxiv txog cov khoom:Kub kub SCR Denitration Catalyst
Rau siab -kev siv kub (xws li, roj kilns, qee yam kev lag luam), peb qhov kub kub SCR Denitration Catalyst yog engineered rau stability nyob rau hauv 300℃mus rau 550℃ib puag ncig. Siv cov cab kuj cordierite, nws tswj kev ua haujlwm qhov twg thermal deactivation yog ib qho kev txhawj xeeb.
Raws li lub Hoobkas thiab cov chaw muag khoom, peb muab tsis yog cov catalysts xwb, tab sis kev txhawb nqa kev koom ua ke. Peb pab neeg ua haujlwm tuaj yeem qhia txog kev xaiv catalyst thiab kho raws li koj qhov tshwj xeeb flue gas profile thiab plua plav.
2. Ozone Oxidation Technology
Txoj kev no siv lub zog oxidizing muaj zog ntawm ozone (O₃) los hloov cov insoluble NO rau hauv nitrogen oxides (NO₂, N₂O₅) uas yooj yim soluble hauv dej. Cov no tau muab tshem tawm ua ke nrog SO₂ hauv cov ntaub ntub dej tom qab siv cov tshuaj alkaline, ua rau nws muaj kev sib xyaw desulfurization thiab denitration technology.
3. Plasma Technology
Qhov no yog txheej txheem kho qhuav uas siv siab - lub zog hluav taws xob los ntawm plasma los ua kom cov tshuaj tiv thaiv oxidation. Nws ib txhij tshem tawm SO₂ thiab NOx los ntawm kev hloov lawv mus rau hauv sulfates thiab nitrates, uas tuaj yeem cuam tshuam nrog ntxiv ammonia los ua cov ntsev ammonium.
Xaus: Xaiv Txoj Cai Technology
Txawm hais tias txhua lub tshuab muaj nws qhov chaw, SCR tseem yog tus qauv ntsuas rau siab -kev tswj hwm NOx hauv kev lag luam loj xws li kev tsim hluav taws xob. Qhov kev xaiv yog nyob ntawm yam xws li flue gas kub, muaj pes tsawg leeg, qhov chaw txwv, thiab yuav tsum tau tshem tawm efficiency.
Koom tes nrog ib tus kws tsim txuj ci
Xaiv cov thev naus laus zis thiab cov khoom siv catalyst zoo yog qhov tseem ceeb rau kev ua haujlwm ntev -. Nrog ntau tshaj kaum xyoo ntawm kev paub dhau los ua cov chaw tsim khoom ceramic thiab tshuaj, Zhongci muaj kev ntseeg siab SCR catalyst cov kev daws teeb meem txhawb nqa los ntawm ISO daim ntawv pov thawj thiab cov neeg siv khoom thoob ntiaj teb.
Nrhiav kom zoo dua koj qhov SCR system lossis tshawb nrhiav cov kev xaiv catalyst?
Tiv tauj peb rau cov ntaub ntawv kev tshaj lij ntawm peb lub siab -kub catalysts lossis los tham txog kev kho kom haum rau koj cov nroj tsuag xav tau.
