Gas dab tsi yog lub tshuab ntsuas roj muaj peev xwm kuaj tau?
Gas Detector yog ib qho cuab yeej tshawb nrhiav uas siv los ntsuas qhov concentration ntawm cov pa tawm. Nws belongs rau cov khoom siv hluav taws xob, feem ntau suav nrog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ruaj khov, thiab lwm yam, feem ntau yog tso siab rau cov pa sensors los ntsuas qhov concentration ntawm ntau yam gases. Nws yog dav siv nyob rau hauv ntau yam kev lag luam rau kev sim. Yog li dab tsi gases tuaj yeem ntes tau?
1. Cov pa roj
Combustible gas yog dab tsi peb feem ntau ntsib nyob rau hauv kev siv cov roj detectors. Lub tswv yim ntawm cov roj combustible yog hais txog cov roj uas tuaj yeem sib xyaw nrog huab cua (lossis oxygen) nyob rau hauv ib qho kev concentration ntau los tsim cov roj premixed uas yuav tawg thaum ntsib qhov hluav taws kub. , ib qho roj uas tso tawm ntau lub zog thaum combustion.
Xws li gases yog ubiquitous nyob rau hauv kev ua hauj lwm ib puag ncig ntawm petrochemical thiab chemical manufacturing industries. Peb cov combustible gases yog hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), propylene (C3H4), butyne (C4H6), thiab lwm yam.
Tag nrho cov saum toj no combustible gases tuaj yeem kuaj tau los ntawm peb cov khoom siv roj. Qee lub tshuab ntsuas roj tsuas yog kuaj tau ib hom roj, thaum lwm tus tuaj yeem kuaj tau ntau yam roj.
2. Cov pa phem
Toxic gas yog ib qho roj uas ua rau tib neeg lub cev muaj kev phom sij thiab tuaj yeem ua rau lom. Nws yog tsuas yog muab faib ua cov pa roj (gas uas irritates lub qhov muag thiab ua pa ib ntsuj av mucous daim nyias nyias) thiab suffocating gas (gas uas yuav ua rau hypoxia nyob rau hauv lub cev). Cov pa roj carbon monoxide tuaj yeem muab faib ua cov pa roj asphyxiating yooj yim, roj asphyxiating roj thiab cell asphyxiating roj), cov roj no tuaj yeem ua rau tib neeg lub cev raug mob, thiab tseem muaj kev phom sij heev, cov pa roj carbon monoxide (CO), hydrogen sulfide ( H2S), ammonia (NH3), chlorine (CL2), sulfur dioxide (SO2), nitrogen dioxide (NO2), nitric oxide (NO), carbon dioxide (CO2), thiab lwm yam.
3. VOC (Volatile Organic Compounds)
Lub tswv yim ntawm VOC yog cov kua organic lossis cov khoom uas tuaj yeem ua rau tsis muaj zog nyob rau hauv qhov kub thiab txias, feem ntau hu ua cov kuab tshuaj organic. Cov khoom siv roj ntau tuaj yeem ntes roj av, diesel, benzene, roj av, xim, thiab lwm yam.
