CEMS yog hais txog ib lub cuab yeej uas tsis tu ncua saib xyuas cov concentration thiab tag nrho cov pa paug ntawm cov pa phem thiab cov khoom paug tawm los ntawm cov pa phem hauv huab cua thiab xa cov ntaub ntawv mus rau lub tuam tsev muaj peev xwm hauv lub sijhawm.Nws yog hu ua "automatic flue gas monitoring system", tseem hu ua "nruam flue gas emission monitoring system" lossis "flue gas on-line monitoring system".CEMS yog tsim los ntawm gaseous pollutant monitoring subsystem, particulate matter monitoring subsystem, flue gas parameter monitoring subsystem and data acquisition and processing and communication subsystem.Lub gaseous pollutant saib xyuas subsystem yog tsuas yog siv los saib xyuas cov concentration thiab tag nrho cov pa paug ntawm gaseous pollutants SO2, NOx, thiab lwm yam;Lub particle saib xyuas subsystem feem ntau yog siv los saib xyuas cov concentration thiab tag nrho cov pa luam yeeb thiab plua plav;Lub flue gas parameter saib xyuas subsystem yog tsuas yog siv los ntsuas qhov flue gas flow rate, flue gas temperature, flue gas siab, flue gas oxygen cov ntsiab lus, flue gas vaum, thiab lwm yam, thiab yog siv rau tsub zuj zuj ntawm tag nrho cov emissions thiab kev hloov ntawm muaj feem xyuam concentration;Cov ntaub ntawv tau txais, ua thiab kev sib txuas lus subsystem yog tsim los ntawm cov ntaub ntawv sau thiab lub computer system.Nws sau ntau yam tsis sib xws hauv lub sijhawm tiag tiag, tsim cov hauv paus qhuav, ntub dej thiab hloov pauv cov concentration sib haum rau txhua tus nqi concentration, tsim tawm txhua hnub, txhua hli thiab ib xyoos ib zaug, ua tiav cov nyiaj them poob haujlwm, thiab xa daim ntawv tshaj tawm mus rau lub tuam txhab muaj peev xwm hauv lub sijhawm. .Cov pa luam yeeb thiab plua plav kuaj yog ua los ntawm tus ntoo khaub lig flue opacity plua plav detector β X-ray plua plav meters tau tsim los ntsaws rau hauv backscattered infrared lub teeb lossis laser plua plav meters, nrog rau pem hauv ntej tawg, sab tawg, hluav taws xob plua plav meters, thiab lwm yam. Raws li cov qauv sib txawv, CEMS tuaj yeem muab faib ua kev ntsuas ncaj qha, ntsuas kev rho tawm thiab ntsuas qhov ntsuas qhov deb.
Dab tsi yog cov khoom ntawm CEMS system?
1. Ib qho kev ua tiav CEMS suav nrog kev saib xyuas cov kab ke, kev soj ntsuam cov pa phem gaseous, flue gas emission parameter xyuas qhov system thiab cov ntaub ntawv tau txais thiab kev ua haujlwm.
2. Particle saib xyuas qhov system: cov khoom feem ntau xa mus rau txoj kab uas hla ntawm 0.01 ~ 200 μ Lub subsystem feem ntau suav nrog particle monitor (soot meter), backwash, cov ntaub ntawv xa mus thiab lwm yam kev pabcuam.
3. Gaseous pollutant monitoring system: Cov pa phem hauv flue gas feem ntau suav nrog sulfur dioxide, nitrogen oxide, carbon monoxide, carbon dioxide, hydrogen chloride, hydrogen fluoride, ammonia, thiab lwm yam. Lub subsystem tsuas yog ntsuas cov khoom paug hauv cov pa roj flue;
4. Flue gas emission parameter monitoring system: feem ntau yog saib xyuas cov pa hluav taws xob tsis zoo, xws li kub, av noo, siab, ntws, thiab lwm yam. Gas tuaj yeem ntsuas tau;
5. Cov ntaub ntawv tau txais thiab ua cov txheej txheem: sau, txheej txheem, hloov thiab tso saib cov ntaub ntawv ntsuas los ntawm kev kho vajtse, thiab xa mus rau lub platform ntawm kev tiv thaiv ib puag ncig los ntawm kev sib txuas lus module;Nyob rau tib lub sijhawm, sau cov sijhawm thiab cov khoom siv raws li txoj cai ntawm blowback, tsis ua haujlwm, calibration thiab txij nkawm.
