Denitration siv ozone denitration technology

Lub denitrification kev kho mob twb tau siv cov oxidative denitrification technology ntawm active molecules (ozone) mus cuag lub hom phiaj ntawm Nox emission qauv. Nyob rau tib lub sij hawm, lub influencing yam tseem ceeb ntawm cov pa concentration, cua txias dej kub thiab boiler load hloov tau analyzed. Cov kev tshwm sim pom tias thaum lub adsorption siab thiab desorption siab ntawm cov VPSA oxygen generator twb 40-48 kPa thiab -45-55 kPa, cov pa concentration mus txog lub pom tus nqi ntawm dua 92%. Cua txias dej kub yuav tsum tsis pub tshaj 32 ° C. Nyob rau tib lub sij hawm, nws yog npaj siab tias lub Nox emission yog ib txwm nyob rau hauv kev ua raws cai nrog rau cov quantitative tswj ntawm lub rooj ntev zaum kom tau raws li lub boiler load hloov.

Nrog lub promulgation ntawm lub "Action Plan rau Tiv Thaiv thiab Tswj ntawm Atmospheric Pollution" thiab ntxiv yuav txo tau ntawm lub emission ntawm flue roj kuab paug los ntawm thee raug rho tawm haujlwm boilers, cov kev tswj ntawm nitrogen oxide Nox tau ntxiv lawm. Scr yog tam sim no ib tug zoo ntawm denitrification technology nrog rau feem ntau zoo tshem tawm efficiency. Txawm li cas los, thaum nrhiav lub hom phiaj ntawm sab Nox emission, qhov no technology yuav ua rau ntev li ammonia plam vim nws xam qhovkev nws thiab sis tsis ncaj txaus teb. Nyob rau tib lub sij hawm, raws li cov catalyst loading nce, conversion tus nqi ntawm SO2 rau SO3 nce, thiab qhov kawg pa luam yeeb Qhov nce ntawm cov concentration ntawm NH3 thiab SO3 nyob rau hauv cov roj yuav ntxiv aggravate qhov jamming ntawm huab cua preheater. Lub oxidative denitrification technology raws li nyob rau hauv uas tsis muaj kub active molecules yog zoo heev yuav tsum tsis txhob saum toj no teeb meem. Sib txawv ntawm cov SCRs, active molecules (xws li O3) yog dab rau synergistic kev kho mob ntawm flue roj los ntawm cov oxidation ntawm kuab paug xws li TSIS thiab hnyav hlau. Qhov no txoj kev muaj tsis muaj dab tsi ua li cas nrog lub hom boiler, tus kwv ntawm kev kho mob yog tus Tsov tus tw hauv paus ntawm lub boiler, cov oxidation ntawm TSIS MUAJ thiab hnyav hlau nyob rau hauv lub flue roj rau high-nqi Nox thiab hlau oxides, thiab ces tus ua kom sib haum ntawm tej pa paug xws li Nox, SO2, thiab hnyav hlau. Tshem tawm.

Nyob rau hauv daim ntawv no, active oxidative denitration technology siv los mus kawm txog cov Nox emission tswj nyob rau hauv thee raug rho tawm haujlwm flue roj, thiab cov yam tseem ceeb uas cuam tshuam denitration efficiency xws li cov pa concentration, cua txias dej kub thiab boiler load hloov tau analyzed.

1, txhim kho cov kev pab cuam

Tus thawj boiler ntawm ib lub hwj chim nroj tsuag yog 2 poob lawm ntawm 35t / h thiab 1 txheej 50t / h saw rauv. Tus thawj ntub desulfurization system siv ib tug txheej ntawm limestone gypsum txoj kev SO2 tshem tawm. Lub active molecular oxidative denitration technology yog thov rau tus Tsov tus tw flue tom qab lub flue roj txuas. Yog li ntawd, tsuas yog tus flue roj txaus tus nqi thiab nitrogen oxide cov ntsiab lus ntawm tus Tsov tus tw flue yuav tsum raug xam tias yog, uas yog kev ywj siab ntawm lub combustion hom ntawm cov boiler. Siv cov thawj desulfurization khoom, tsuas yog tus thawj flue roj desulfurization ntauwd inlet flue twb hloov thiab ib tug active molecular reactor twb ntsia. Tus so ntawm lub transformations yog tshiab li raws li qhia nyob rau hauv Daim duab 1. Pa system, active molecular system, cua txias dej system thiab hluav taws xob thiab ntsuas tswj koom haum pab systems. Cov pa oxygen system siv ib tug adsorbent cais cov pa thiab nitrogen nyob rau hauv cov huab cua los ntawm adsorption thiab desorption yuav tsim ib tug ntau dua concentration ntawm cov pa. Tom qab pressurization, deoiling, thiab plua plav tawm, cov pa nkag rau hauv lub active molecular generator, thiab thaum kawg tus active molecule (O3) yog generated los ntawm ib nrab paug nyob rau hauv lub paug chamber. Lub paug high-voltage hluav taws xob mus rau lub oxygen nyob rau hauv lub paug chamber generates ib tug loj npaum li cas ntawm tshav kub, yog li lwm txias dej yog yuav tsum tau los ua cua sov-kho cov paug chamber ua rau kom cov concentration ntawm lub active molecule (O3).
