Dab tsi gases tuaj yeem ntes tau?
Daim ntawv thov ntau ntawm cov khoom siv roj av tau dhau los ua qhov dav. Feem ntau siv hauv kev lag luam petrochemical, kev lag luam kho dej, kev lag luam tshuaj, kev lag luam tshuaj, thiab kev lag luam zaub mov, nws muaj ntau yam kev siv.
Hauv ntau lub lag luam kws tshuaj, vim tias muaj ntau cov khoom siv raw thiab cov khoom nruab nrab yog cov nplaim hluav taws, tawg lossis cov tshuaj lom neeg, muaj cov pa paug ntawm cov tshuaj lom neeg, tsim kev puas tsuaj lossis nplaim hluav taws thaum lub sijhawm tsim tshuaj thiab cov txheej txheem tshuaj. Xaiv lub tswb hluav taws xob tsim hluav taws xob lossis lub ntsuas hluav taws xob rau kev tshawb nrhiav, uas tuaj yeem tshawb xyuas qee cov pa roj carbon monoxide zoo, ua kom muaj kev soj ntsuam zoo, thiab ua kom muaj kev nyab xeeb.
Gas detector yog ib qho cuab yeej cuab tam rau kev ntes los yog ceeb toom roj to concentration, feem ntau muab faib ua handheld / tsau roj detectors. Nws siv cov pa sensors los kuaj xyuas cov pa roj uas muaj nyob hauv ib puag ncig, feem ntau yog siv los txheeb xyuas cov pa roj carbon monoxide, cov roj hluav taws xob hluav taws xob, lossis cov ntsiab lus ntawm cov pa oxygen.
Cov pa roj carbon monoxide yog cov pa roj ntau tshaj plaws hauv kev siv cov khoom siv hluav taws xob. 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. Thaum ntsib qhov hluav taws kub, nws yuav tawg thiab tso tawm ntau lub zog thaum lub sij hawm combustion.
Cov pa roj no muaj nyob rau hauv ib puag ncig ua haujlwm hauv kev lag luam xws li petrochemical thiab kev tsim tshuaj lom neeg. Peb cov combustible gases muaj xws li hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), acetylene (C3H4), butyne (C4H6), thiab lwm yam.
Cov pa phem yog hais txog cov pa roj uas tsim kev puas tsuaj rau tib neeg lub cev thiab tuaj yeem ua rau lom. Lawv feem ntau muab faib ua cov pa roj carbon monoxide (xa mus rau cov pa roj uas ua rau lub qhov muag thiab ua pa mucosa) thiab cov pa roj suffocating (hais txog cov pa roj carbon monoxide uas tuaj yeem ua rau hypoxia hauv lub cev. cell suffocating gases). Cov pa roj no tuaj yeem ua rau tib neeg lub cev raug mob thiab tseem txaus ntshai 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.
