Hauj lwm

SCR yog cov txheej txheem kev kho mob rau nitrogen oxides hauv cov pa tawm ntawm cov tsheb diesel, uas yog, nyob rau hauv qhov kev txiav txim ntawm catalysts, nitrogen oxides hauv cov pa tso pa raug txo kom nitrogen thiab dej uas tsis muaj kev phom sij rau huab cua.

Haum rau kev kho tom qab ntawm lub cav diesel NOx emissions. Nyob rau pem hauv ntej kawg ntawm SCR catalyst, urea yog qhia raws li ib tug txo tus neeg sawv cev. Tom qab urea yog hydrolyzed rau NH3, NO thiab NO2 hauv cov pa tso pa raug txo kom N2, thiab NOx raug tshem tawm zoo nyob rau hauv cov pa oxygen-enriched ntawm lub cav diesel. Nws muaj qhov kub thiab txias ua haujlwm zoo, qhov kub thiab txias qhov rais thiab ruaj khov, thiab tuaj yeem ua tau raws li Euro V emission tus qauv thaum sib txuam nrog tag nrho lub tshuab. Cov khoom tsim nyog rau lub teeb-lub luag haujlwm diesel tsheb (xws li tsheb, SUVs, MPVs) ntawm txoj kev, tsheb loj diesel (xws li tsheb npav, tsheb thauj khoom hnyav, forklifts, thiab lwm yam), nrog rau lwm yam tsis siv tsheb. cav tsau cov cuab yeej lossis cov khoom siv.

Selective catalytic reduction (SCR) catalyst yog cov khoom siv high-tech dav siv nyob rau hauv thermal fais fab nroj tsuag, thee-fired fais fab nroj tsuag, khib nyiab incineration nroj tsuag, hlau thiab steel nroj tsuag, chiv, nroj tsuag nitric acid, cement nroj tsuag, petrochemical tshuaj nroj tsuag thiab lwm yam. kev lag luam uas yuav tsum tau txo cov NOx emissions. Selective catalytic reduction (SCR) catalyst yog ib tug denitration catalyst nyob rau hauv qhov tsim nyog qhov kub thiab txias, siv ammonia (NH3) raws li tus neeg sawv cev txo, coj kom zoo dua ntawm cov txo tus neeg sawv cev xaiv, nyiam cov tshuaj tiv thaiv nrog muaj flue gas ntawm nitrogen oxide (NOx), NOx yog hloov mus rau hauv tsis muaj kuab paug ntawm nitrogen thiab dej, thiab NOx txo efficiency yog siab tshaj li 90%. peb SCR de-nitrogen catalyst tau tsim los ntawm kev siv cordierite honeycomb ceramics ua kev txhawb nqa, siv TiO2, CuO, V2O5, Tsis tshua muaj ntiaj teb thiab WO3 ua cov khoom tseem ceeb. Nws muaj qhov zoo ntawm lub zog thiab kev tiv thaiv ntawm ya tshauv clogging, hnav thiab tiv thaiv tshuaj lom.
