Classification thiab daim ntawv thov ntau yam ntawm cov roj detectors
Nyob rau hauv lub neej niaj hnub, nrog rau kev loj hlob ntawm kev lag luam, ntau thiab ntau cov gases raug tsim. Qee qhov ntawm cov pa roj no yog cov nplaim hluav taws kub thiab tawg, thiab qee qhov muaj tshuaj lom thiab muaj kev phom sij, uas faus ntau yam kev phom sij rau tib neeg lub neej thiab ib puag ncig huab cua. Yog li ntawd, thaum ua kev lag luam ntau lawm, peb yuav tsum tau them sai sai rau kev tswj emissions ntawm ntau yam gases, thiab siv ntau yam gas detectors los ua scientific thiab zoo tswj cov pa emissions. Muaj ntau yam kev faib tawm ntawm cov khoom siv roj av, cov kev faib tawm tshwj xeeb yog raws li hauv qab no.
Raws li txoj kev siv, nws tuaj yeem muab faib ua taag thiab portable.
1. Tsau roj ntes
Lub ntsuas roj ruaj ruaj yog kho ntawm qhov chaw xau ntawm qhov chaw rau kev tshawb pom cov pa tawm hauv lub sijhawm. Thaum kuaj pom cov pa tawm thiab cov pa tawm ntawm cov pa tawm mus txog qhov ntsuas tus nqi ntawm lub tshuab ntes, lub tshuab ntes yuav xa tawm lub suab nrov thiab pom lub tswb ceeb toom thiab tswj tau qhov qhib ntawm cov pa tawm. Ntxuam, solenoid li qub thiab lwm yam khoom siv.

2. Portable roj ntes
Sab hauv ntawm lub portable gas detector muaj xws li sensors, ntsuas circuits, qhia, tswb, rechargeable roj teeb, cua twj thiab lwm yam khoom. Lub portable gas detector yog me me thiab lub teeb nyob rau hauv tsos, yooj yim mus nqa, thiab muaj ob txoj kev kuaj: diffusion hom thiab twj tso kua mis suction hom. Nws yog qhov yooj yim rau cov neeg ua haujlwm ntawm qhov chaw ua haujlwm sim txhua lub sijhawm thiab nyob qhov twg.
Classification thiab daim ntawv thov ntau yam ntawm cov roj detectors
Raws li kev faib tawm ntawm cov sensors, nws tuaj yeem muab faib ua combustible gas detectors; catalytic combustion combustible gas detectors; electrochemical toxic gas detectors, kuaj CO, H2S, NO, NO2, CL2, HCN, NH3, PH3 thiab ntau yam tshuaj lom organic tebchaw; Infrared combustible gas detector mus ntes ntau yam combustible gases (raws li filtering technology); semiconductor combustible gas detector kom paub ntau yam combustible gases; thermal conductivity combustible gas detector kom paub qhov txawv ntawm nws thermal conductivity thiab huab cua Hydrogen, thiab lwm yam .; toxic gas detector (hu ua tshuaj lom detector, ib qho cuab yeej los kuaj xyuas cov pa phem); photoionization toxic gas detector, kuaj cov organic thiab inorganic tebchaw nrog ionization muaj peev xwm tsawg dua 11.7eV; infrared toxic gas detection instrument, ntes CO, CO2, thiab lwm yam .; semiconductor toxic gas detector, ntes CO, thiab lwm yam.
Dab tsi yog daim ntawv thov ntau yam ntawm gas detectors
Gas detectors yog siv nyob rau hauv ntau yam kev siv. Piv txwv li: Alkanes, benzenes, cawv, roj av, hydrogen, hydrogen sulfide, carbon monoxide thiab lwm cov pa roj carbon monoxide thiab cov pa phem, ib zaug xau, sib xyaw nrog cov huab cua ib puag ncig los tsim cov khoom tawg. Nyob rau hauv qhov chaw muaj kev phom sij tawg, ib zaug muaj hluav taws kub lossis kub qhov chaw, thiab cov roj combustible tsuas yog nyob rau hauv thaj tsam ntawm cov khoom tawg, nws yuav ua rau hluav taws kub thiab tawg, ua rau muaj kev puas tsuaj loj rau kev nyab xeeb ntawm lub neej thiab khoom. Gas detectors tuaj yeem siv dav hauv roj av, tshuaj lom neeg, thee, thiab lwm yam kev lag luam uas muaj ntau yam khoom siv hluav taws xob thiab hluav taws xob tawg lossis cov kua dej tuaj yeem xau thaum tsim khoom, ua haujlwm thiab kev thauj mus los.
Rau cov cuab yeej siv roj, nws tsis yog tsuas yog yuav tsum xaiv cov khoom siv hluav taws xob uas tsim nyog, tab sis kuj yuav tsum siv cov txheej txheem ua haujlwm kom raug thiab kev saib xyuas raws sijhawm kom ntseeg tau tias kev ua haujlwm zoo ntawm cov cuab yeej siv roj thiab ua kom lawv lub neej ua haujlwm ntev txhawm rau ua kom lawv lub luag haujlwm loj tshaj plaws.
