Dab tsi yog qhov txawv ntawm combustible gas thiab toxic gas detectors
Lub combustible gas detector feem ntau kuaj cov roj combustible thiab siv methane raws li tus qauv los xyuas qhov concentration ntawm combustible gases. Raws li qhov sib txawv combustible gases nyob rau hauv cov neeg siv qhov chaw, cov roj concentration yuav tsum tau teem raws li lub ntsiab roj raws li tus qauv rau kev kuaj.
Kev kuaj pom cov pa hluav taws xob feem ntau yog siv nyob rau hauv cov xwm txheej xws li roj av thiab tshuaj lom neeg kev lag luam uas muaj cov pa phem uas tsis zoo, feem ntau yog tsom rau cov pa roj carbon monoxide xws li alkanes thiab inorganic gases xws li methane thiab carbon monoxide. Cov pa roj carbon monoxide nce mus txog qee qhov concentration, ua ke nrog cov pa oxygen txaus thiab qhov hluav taws kub, yuav ua rau tawg. Kev tawg tuaj yeem nrog cov hluav taws kub loj thiab kev sib tsoo, ua rau muaj kev hem thawj rau kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom ntiag tug. Yog li ntawd, nyob rau hauv kev lag luam uas tsim volatile organic tebchaw thaum lub sij hawm tsim thiab tsim, nws yog ib qho tseem ceeb uas yuav tsum tau siv tej combustible gas detection raws li ib tug kev ruaj ntseg tsim qauv, vim hais tias feem ntau volatile organic tebchaw yog flammable.
Lub tshuab kuaj roj toxic yuav tsum paub seb cov roj tshwj xeeb lossis cov pa phem twg los kuaj xyuas. Koj tuaj yeem xaiv lub tswb ntsuas tshuaj lom neeg sib cais lossis cov khoom siv tshuaj lom neeg sib xyaw, nyob ntawm seb cov pa tshuaj lom hauv thaj chaw siv yuav tsum tau kuaj pom rau ib qho roj lossis ntau cov pa roj.
Daim ntawv thov thaj tsam ntawm kev kuaj pom cov pa tshuaj lom yog qhov dav dua, tsom mus rau cov khoom siv hluav taws xob tsis zoo (VOCs) uas muaj nyob hauv cov khoom siv raw, lossis cov pa roj xws li ammonia (NH3), carbon monoxide (CO), hydrogen sulfide (H2S), chlorine (CL2), hydrogen cyanide (HCN), nitric oxide (NO), sulfur dioxide (SO2) tsim nyob rau hauv cov txheej txheem ntau lawm. Cov pa roj carbon monoxide uas muaj ntau tshaj li cov qauv tshwj xeeb tuaj yeem ua rau tib neeg lub cev tsis zoo, ua rau muaj ntau yam kab mob, thiab hauv cov xwm txheej hnyav, ua rau tuag taus. Nyob rau tib lub sijhawm, kev saib xyuas cov pa phem thiab cov pa phem no yog qhov teeb meem uas lub teb chaws tseem ceeb heev rau kev tiv thaiv cov kab mob ua haujlwm.
Qhov txawv ntawm combustible gas thiab toxic gas detectors yog tias combustible gas detectors siv catalytic combustion gas sensors, hos cov pa roj toxic detectors siv electrochemical sensors, infrared sensors, los yog PID sensors. Chav tsev concentration cov ntsiab lus ntawm cov roj pom tau txawv.
