2026-05-26 IB

Lub hauv paus ntsiab lus tseem ceeb ntawm kev xaiv CEMS yog qhov yooj yim: tsis muaj kev siv tshuab zoo tshaj plaws hauv ntiaj teb, tsuas yog cov kev daws teeb meem zoo tshaj plaws rau cov txheej txheem tshwj xeeb thiab cov roj flue. Tus nqi ntawm tus kws tshaj lij kev lag luam nyob rau hauv kev nkag siab txog cov khoom lag luam tag nrho thiab pom zoo rau lub hom phiaj, kev teeb tsa kev sib raug zoo rau txhua qhov chaw.

1. Peb lub ntsiab CEMS Technology Routes

1.1 Txoj Kev Kub Kub Txhuam: UV DOAS Nrog Zirconia Oxygen Ntsuas

Lub hauv paus ntsiab lus: cov qauv roj tau khaws cia siab tshaj 140 ° C los ntawm kev ntsuas mus rau kev soj ntsuam, thiab cov pa phem yog ntsuas los ntawm ntub dej. Oxygen feem ntau ntsuas nrog lub zirconia oxygen analyzer. Hauv cov ntsiab lus yooj yim, txoj kev kub-ntub tso cai rau cov qauv roj nkag mus rau hauv lub ntsuas ntsuas thaum khaws cia nws cov xwm txheej qub ntau li ntau tau.

Kev ntsuas kub ntawm lub twj tso kua mis: lub kaw lus tsis cia siab rau ejector-tswj sampling, uas ua rau kev kuaj xyuas thiab tu niaj hnub yooj yim dua.
Cov ntaub ntawv siab tshaj plaws: kev ntsuas kub tsis tu ncua kom tsis txhob muaj kev sib cais ntawm cov dej-soluble gases xws li SO2 thiab NH3, tso cai rau tus neeg soj ntsuam ntsuas qhov tseem ceeb ntub dej hauv cov flue.
Cov lus teb ceev ceev: vim tias tsis muaj cov txheej txheem dehumidification thiab cov roj txoj kev luv luv, lub ntsuas ntsuas tuaj yeem teb sai dua rau cov txheej txheem hloov pauv.
Tsis muaj condensate wastewater: txoj kev zam cov pa phem thib ob los ntawm acidic condensate thiab txo cov dej khib nyiab.
Mature thiab txhim khu kev qha technology: lub system qauv yog kuj yooj yim, txhawb kev ruaj khov mus sij hawm ntev kev lag luam.

Kub-ntub CEMS tshwj xeeb tshaj yog tsim rau kev tswj cov txheej txheem, desulfurization thiab denitrification efficiency xam, ntub-raws li kev soj ntsuam thiab kev siv qhov twg qhov tseeb roj-theem mob yuav tsum tau khaws cia.

1.2 Txoj Kev Txias-Dry: UV DOAS Nrog Electrochemical Oxygen Measurement

Lub hauv paus ntsiab lus: tom qab kuaj, cov qauv roj tau nrawm nrawm mus rau kwv yees li 4 ° C kom tshem tawm feem ntau ntawm cov dej noo, thiab cov pa phem tau ntsuas ntawm lub hauv paus qhuav. Oxygen feem ntau yog ntsuas los ntawm electrochemical oxygen analyzer. Txoj kev txias-qhuav tsim ib qho chaw huv, qhuav thiab ruaj khov ntsuas qhov ntsuas qhov tseeb.

Kev tiv thaiv corrosion zoo heev: rau cov roj flue uas muaj cov khoom corrosive heev xws li HF, HCl lossis H2SO4 vapor, ceev condensation tshem tawm cov kua qaub ntau ntawm cov dej noo thiab pab tiv thaiv kev sojntsuam, kav dej, twj tso kua mis, li qub thiab ntsuas ntsuas.
Muaj peev xwm tswj tau txoj kev cuam tshuam tsis yooj yim: lub pretreatment platform tuaj yeem txhawb nqa ntau theem thiab ntau txoj kev teeb tsa, uas yog qhov muaj txiaj ntsig zoo thaum H2S, organics thiab lwm yam cuam tshuam kev sib koom ua ke.
Cov kev ntsuas ruaj khov: cov roj ua kom huv huv thiab qhuav cov qauv roj muab qhov chaw kho qhov muag ruaj khov rau UV DOAS cov kws tshuaj ntsuam xyuas, txo qis qis qis thiab txhim kho cov teeb liab-rau-suab nrov piv.
Cov ntaub ntawv oxygen ntseeg tau: electrochemical oxygen ntsuas tsis cuam tshuam los ntawm cov khoom siv roj hluav taws xob xws li CO thiab H2, muab O2 tus nqi rau kev hloov pauv emissions.

1.3 Hybrid Solution: Kub-Wet Pollutant Measurement Plus Cold-Dry Oxygen Measurement

Cov tshuaj hybrid ua raws li lub tswv yim ntawm kev khaws cia cov pa roj tseem ceeb thaum tau txais txiaj ntsig zoo dua cov pa oxygen los ntawm txoj kev sab. Cov pa phem xws li SO2, NO thiab NO2 yog ntsuas los ntawm cov txheej txheem kub ntub dej nrog UV DOAS thev naus laus zis, thaum O2 ntsuas tom qab cov qauv roj yog condensed thiab qhuav nyob rau hauv ib qho bypass, feem ntau nrog electrochemical lossis paramagnetic oxygen analyzer.

Cov ntaub ntawv pov thawj kev ncaj ncees ntxiv rau kev ntsuas cov pa oxygen kom raug: txoj hauv kev tseem ceeb khaws cia qhov tseem ceeb ntub dej ntawm SO2 thiab NOx thaum lub bypass zam qhov kev txwv ntawm zirconia oxygen ntsuas nyob rau hauv high-CO tej yam kev mob.
Lub hom phiaj tshwj xeeb rau kev lag luam tshwj xeeb: kev daws teeb meem tshwj xeeb yog tsim rau electrolytic aluminium, txiv qaub kilns, ceramic kilns thiab lwm qhov chaw uas muaj CO siab ua rau zirconia oxygen ntsuas tsis ntseeg.
Sib npaug kev ntseeg tau thiab tus nqi kho: piv nrog cov dej kub ntub dej, txoj kev sib xyaw ua ke tuaj yeem hloov zirconia oxygen ntsuas nrog lub ntsuas oxygen yooj yim dua. Piv nrog rau tag nrho cov txias-qhuav, tsuas yog O2 bypass yuav tsum tau dehumidification.
Ntau dua tag nrho cov ntaub ntawv kev ntseeg siab: vim O2 yog siv rau hauv kev sib hloov siab los ntawm kev ntsuam xyuas ib puag ncig, cov ntaub ntawv cov pa oxygen ncaj qha txhim kho qhov kev ntseeg siab ntawm qhov kawg hloov pauv emissions concentrations.

4. Cov lus nug nquag nug txog kev xaiv CEMS

Puas yog txoj kev kub-ntub ib txwm zoo dua li txoj kev txias-qhuav?

Tsis yog. Txoj kev ntub dej kub yog qhov zoo tshaj plaws rau kev khaws cia cov roj ntub dej hauv paus, tshwj xeeb tshaj yog rau SO2, NH3 thiab cov txheej txheem tswj kev siv. Txawm li cas los xij, nyob rau hauv cov kab mob corrosive heev los yog cov roj flue nyuaj heev, txoj kev txias qhuav tuaj yeem muab kev tiv thaiv zoo dua thiab ruaj khov mus ntev.

Vim li cas kev ntsuas oxygen tseem ceeb hauv CEMS?

Oxygen cov ntaub ntawv yog siv rau emissions concentration conversion. Yog tias tus nqi O2 tsis raug, qhov kawg hloov pauv cov kuab paug siab kuj tseem yuav tsis ntseeg. Qhov no yog vim li cas hybrid CEMS cov kev daws teeb meem yog qhov tseem ceeb hauv high-CO cov xwm txheej uas zirconia oxygen ntsuas tuaj yeem cuam tshuam.

Dab tsi yog txoj hauv kev zoo tshaj los xaiv CEMS kev daws teeb meem?

Txoj hauv kev zoo tshaj plaws yog pib los ntawm cov txheej txheem tiag tiag: noo noo, corrosive gases, soluble pollutants, combustible gases, hla kev cuam tshuam, kev tswj hwm thiab kev saib xyuas. Ib qho kev sib tw CEMS kev daws teeb meem yuav tsum raug xaiv tsuas yog tom qab cov xwm txheej ntawm lub xaib no nkag siab.
