Txheem rau hydrogen sulfide tswb nqi ntawm plaub nyob rau hauv ib tug gas detector
Kev teeb tsa ntawm hydrogen sulfide tswb tus nqi rau plaub hauv ib lub ntsuas roj yog qhov tseem ceeb heev, vim nws yuav tsum tau txiav txim siab tus nqi tsim nyog raws li cov qauv thiab cov cai. Hydrogen sulfide yog cov pa phem heev uas ua rau muaj kev phom sij rau tib neeg lub cev thiab ib puag ncig. Yog li ntawd, nrhiav kom tau ntxov thiab tswb yog qhov tseem ceeb heev.
Raws li lub teb chaws tus qauv GBZ 2. Cov qauv no muab qhov kev pom zoo ntau yam rau hydrogen sulfide hauv chaw ua haujlwm.
Raws li lub teb chaws tus qauv "GB/T 50493-2019 Tus Qauv Tsim Qauv rau Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Tswb Hauv Kev Lag Luam Petrochemical", qhov ntsuas ntau yam ntawm cov pa phem yuav tsum yog 0-300 feem pua OEL, nrog rau OEL ntawm 10mg /m3. Tus nqi ceeb toom thawj theem yuav tsum tsawg dua lossis sib npaug li 100 feem pua OEL, piv txwv li 10mg / m3, thiab qib thib ob lub tswb tus nqi yuav tsum tsawg dua lossis sib npaug li 200 feem pua OEL, piv txwv li 20mg / m3. Thaum qhov ntsuas qhov ntsuas ntawm lub ntsuas ntsuas uas twb muaj lawm tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, tus nqi ceeb toom thawj theem yuav tsum tsis pub tshaj 5 feem pua IDLH, thiab qib thib ob tus nqi tswb yuav tsum tsis pub tshaj 10 feem pua IDLH.
Raws li qhov yuav tsum tau ua ntawm cov qauv saum toj no, peb tuaj yeem tuaj nrog cov lus qhia hauv qab no rau kev teeb tsa lub tswb ntsuas hydrogen sulfide ntawm plaub hauv ib lub ntsuas roj:
1. Kev ntsuas ntau: 0-30mg / m3, sib npaug rau qhov ntim siab ntawm 0-20ppm.
2. Thawj theem qis lub tswb teeb taw tes (AL): tsis tshaj 10mg / m3, piv txwv li tsis tshaj qhov ntim ntawm 6.5ppm.
3. Secondary high alarm set point (AH): tsis tshaj 20mg/m3, piv txwv li tsis tshaj 12ppm ntim concentration.
Lub tswb ntsuas tus nqi teev nyob rau hauv txoj kev no tuaj yeem ua kom lub tswb nrov raws sijhawm thaum muaj kev nyab xeeb siab tshaj, tiv thaiv kev noj qab haus huv thiab kev nyab xeeb ntawm cov neeg ua haujlwm.
Thaum xaiv plaub qhov tshwj xeeb hauv ib lub ntsuas roj, yuav tsum tau them nyiaj rau nws qhov zoo thiab kev ua haujlwm. Lub tshuab ntsuas roj zoo yuav tsum muaj cov yam ntxwv ntawm qhov raug siab, siab rhiab heev, cov lus teb ceev ceev, thiab kev ruaj ntseg thiab kev ntseeg tau. Nyob rau tib lub sijhawm, cov cuab yeej siv tau yooj yim rau kev khiav lag luam thiab nqa tau yooj yim, uas tuaj yeem ua tau raws li qhov xav tau ntawm qhov chaw ua haujlwm sib txawv thiab kev xav tau.
Nyob rau hauv luv luv, teem lub tswb hydrogen sulfide tus nqi ntawm plaub nyob rau hauv ib tug gas detector tsim nyog yog ib qho tseem ceeb rau kev tiv thaiv kev noj qab haus huv thiab kev nyab xeeb ntawm cov neeg ua hauj lwm nyob rau hauv lub chaw ua hauj lwm. Thaum teeb tsa lub tswb ntsuas qhov tseem ceeb, kev siv yuav tsum tau ua rau cov qauv tseem ceeb hauv lub tebchaws los xyuas kom meej tias cov txiaj ntsig tau teeb tsa tuaj yeem teeb tsa lub tswb raws sijhawm thiab ua haujlwm tau zoo, txo cov kev pheej hmoo thiab kev phom sij. Nyob rau tib lub sijhawm, thaum xaiv thiab siv cov cuab yeej siv roj, kev saib xyuas yuav tsum tau them rau lawv cov kev ua tau zoo thiab kev ua haujlwm kom ntseeg tau qhov tseeb thiab kev ntseeg siab ntawm cov cuab yeej.
