Selective Catalytic Reduction (SCR) Catalysts rau Ntiaj Teb Kev Lag Luam
Selective Catalytic Reduction technology plays lub luag haujlwm tseem ceeb hauv kev txo qis nitrogen oxide emissions. Raws li kev tswj hwm thoob ntiaj teb nruj, kev lag luam xav tau SCR catalysts ruaj khov thiab ua haujlwm tau zoo. Pingxiang Zhongci Environmental Ceramics Material Co., Ltd. muab cov kev daws teeb meem siab tshaj SCR catalyst rau kev lag luam thoob ntiaj teb. Zhongci ua lub chaw tsim khoom ntseeg siab thiab cov khoom lag luam loj rau cov chaw tsim hluav taws xob, boilers, thiab cov chaw tsim khoom.
Nkag siab Catalyst Deactivation hauv SCR Systems
Catalyst deactivation ncaj qha cuam tshuam rau DeNOx efficiency. Yog li ntawd, kev nkag siab txog deactivation mechanisms pab txhim kho kev ntseeg tau. Tshuaj lom neeg tshwm sim thaum kab impurities hnov mob nrog cov chaw nquag. Raws li qhov tshwm sim, kev ua haujlwm catalytic poob qis heev. Hauv qhov sib piv, kev lom neeg lub cev tshwm sim thaum qhov chaw ua thaiv lossis npog. Yog li ntawd, txoj kev tshuaj tiv thaiv tau raug txwv.
Hom Kev Cuam Tshuam Ntawm Lub Cev Catalyst Poisoning
1. Lub cev lom neeg tshwm sim ntau zaus thaum lub sijhawm ua haujlwm ntev -SCR. Ua ntej, catalyst abrasion tshwm sim los ntawm siab -flue gas. Nyob rau tib lub sij hawm, nto hnav yuav txo tau cov khoom raug. Tsis tas li ntawd, kev teeb tsa thiab kev hloov pauv tuaj yeem ua rau cov qauv catalyst puas.
2. pore thiab channel blockage txo cov roj diffusion. Cov hmoov tshauv ya zoo thiab cov ntsev ammonium feem ntau ua rau muaj kev thaiv sab hauv. Yog li ntawd, huab hwm coj hloov efficiency poob tsis tu ncua.
3. txheej txheej lom tshwm sim thaum Al₂O₃ thiab SiO₂ tso rau ntawm qhov chaw catalyst. Cov deposits no thaiv micropores. Yog li ntawd, active nto cheeb tsam txo qis.
4. catalyst sintering ua ib qho tseem ceeb deactivation. High -kub raug ua rau particle agglomeration. Thaum cov roj flue kub tshaj 400 degree, sintering accelerates. Ntxiv mus, anatase TiO₂ maj hloov mus rau hauv rutile TiO₂. Yog li ntawd, kev ua haujlwm catalytic tsis muaj zog.
SCR Catalyst Forms rau txawv kev ua haujlwm
SCR catalysts muaj nyob rau hauv ntau hom qauv. Honeycomb catalysts muaj kev poob qis thiab qhov chaw siab. Yog li ntawd, lawv haum rau feem ntau cov kev siv fais fab nroj tsuag. Corrugated phaj catalysts muab kev kho kom zoo dua qub. Yog li ntawd, lawv ua tau zoo nyob rau hauv siab - plua plav ib puag ncig. Phaj- hom catalysts xa cov kev tiv thaiv zoo rau kev yaig. Yog li, lawv haum rau hnyav industrial tej yam kev mob.
Zhongci engineers xaiv cov ntaub ntawv catalyst raws li cov plua plav concentration thiab qhov chaw nyob. Qhov kev hloov kho no ua kom ruaj khov ntev - lub sijhawm ua haujlwm.
High-Tsuas Kub thiab Tsawg-Tsuas SCR Catalysts
SCR catalysts kuj raug cais los ntawm kev ua haujlwm kub. High -kub catalysts ua haujlwm siab tshaj 320℃. Tam sim no, cov khoom no tseem muaj kev paub tab thiab siv dav. Hauv qhov sib piv, qis-kub catalysts ua haujlwm ntawm 280℃thiab 320℃. Txawm hais tias nyuaj, Zhongci tseem txhim kho qis - cov qauv ntsuas kub. Yog li ntawd, cov neeg siv khoom tau txais kev xaiv yooj yim dua installation.
Cov khoom sib xyaw ntawm Modern SCR Catalysts
SCR catalysts sib txawv los ntawm raw khoom muaj pes tsawg leeg. Platinum-raws li catalysts tshwm sim thawj zaug. Txawm li cas los xij, cov nqi siab thiab cov nyom tshauv nruj txwv lawv siv. Yog li ntawd, fais fab nroj tsuag tau phased lawv tawm.
Niaj hnub no, titanium-raws li vanadium catalysts ua lag luam. Feem ntau SCR catalysts siv TiO₂ ua tus cab kuj. Cov khoom nquag muaj xws li V₂O₅, WO₃, thiab MoO₃. Cov hlau oxides suav nrog ntau dua 99% ntawm cov khoom siv catalyst. Meanwhile, kab additives ntxiv txhim khu kev ua tau zoo. Txawm li cas los xij, cov formulations tseeb tseem muaj tswv.
Zhongci siv cov txheej txheem ceramic ua tiav. Yog li ntawd, catalyst purity thiab sib xws nyob twj ywm siab heev.

Cov qauv sib txawv thiab kev ua haujlwm cuam tshuam
Phaj-hom SCR catalysts siv iav fiber ntau thiab TiO₂ substrates. Active cov ntaub ntawv txheej txheej tusyees. Txawm li cas los xij, cov hmoov tshauv loj heev ua rau cov khaubncaws sab nraud povtseg. Thaum puas lawm, kev ua haujlwm catalytic poob mus tas li. Yog li ntawd, regeneration yuav luag tsis yooj yim sua. Zhongci hais txog qhov kev sib tw no los ntawm cov txheej txheem ceramic thiab cov txheej txheem zoo.
Kev Pabcuam Lub Neej thiab Hloov Cycles
SCR catalyst kev pabcuam lub neej feem ntau yog peb xyoos. Txawm li cas los xij, lub neej tiag tiag nyob ntawm kev ua haujlwm. Qee lub tshuab tshaj peb xyoos. Lwm tus xav tau kev hloov ua ntej. Peb muab kev ntsuam xyuas kev ua kom zoo rau cov sijhawm hloov pauv. Yog li ntawd, cov neeg siv khoom txo cov nqi khiav lag luam zoo.
