Tswb tus nqi ntawm hydrogen sulfide gas detector
Tswb tus nqi ntawm hydrogen sulfide gas detector Hydrogen sulfide yog ib qho tseem ceeb tshuaj raw khoom, uas yog heev txaus ntshai rau tib neeg lub cev thiab ib puag ncig. Nws yuav tsis tsuas yog ua rau cov neeg ua haujlwm lom, tab sis kuj ua rau hluav taws kub thiab tawg. Kev tuag thiab hluav taws kub nyhiab tshwm sim los ntawm hydrogen sulfide tsis tshua muaj tshwm sim. Hauv ib puag ncig uas muaj hydrogen sulfide, nws cov concentration yuav tsum raug kuaj pom. Yog li yuav ua li cas teeb tsa tus nqi tswb ntawm hydrogen sulfide gas detection tswb, cia peb saib hauv qab no.
Qhov kev txwv qis dua (LEL) thiab qhov txwv tsis pub tshaj tawm (UEL) ntawm hydrogen sulfide yog 4 feem pua thiab 44 feem pua , raws li, thiab qhov txwv kev ua haujlwm (OEL) yog 10mg / m³. Nyob rau hauv "GBT50493 Petrochemical Combustible Gas thiab Toxic Gas Detection and Alarm Design Standard", nws tau teev tseg tias ib qho roj nruab nrab uas yog ob qho tib si flammable gas thiab toxic gas yuav tsum tau nruab nrog ib tug toxic gas detector. Raws li cov kev cai, thawj-theem tswb teeb tus nqi ntawm cov pa phem yuav tsum tsawg dua los yog sib npaug rau 100 feem pua OEL, thiab qhov thib ob-theem tswb teeb tus nqi yuav tsum tsawg dua los yog sib npaug rau 200 feem pua OEL; uas yog hais tias, thawj-theem tswb tus nqi ntawm hydrogen sulfide gas detector yuav tsum tsawg tshaj li 10mg / m³, lub thib ob tswb nqi yuav tsum tsawg tshaj li 20mg / m³.
Muaj ntau lub sijhawm uas muaj hydrogen sulfide, xws li cov roj extraction thiab refining txheej txheem; mining thiab hlau smelting ua; qis-kub coking ntawm thee; roj hmab, tawv, xim, suab thaj thiab lwm yam txheej txheem; Hydrogen sulfide tej zaum yuav raug tsim thaum kho; nyob rau hauv cov txheej txheem ntawm kev kho dej phwj hauv cov chaw kho dej phwj; nyob rau hauv volcanic eruptions, thiab lwm yam Hydrogen sulfide yog ib tug muaj zog neurotoxin, uas muaj ib tug muaj zog stimulating nyhuv ntawm mucous daim nyias nyias, thiab yuav ua rau lub qhov muag irritation, photophobia, stinging mob, qhov muag tsis pom kev, tearing thiab lwm yam tsos mob; Kev ua pa ua pa tuaj yeem ua rau hnoos, khaus caj pas, ua tsis taus pa, Thaum mob hnyav, pulmonary edema tuaj yeem tshwm sim. Tsis tas li ntawd, lub paj hlwb yuav raug puas tsuaj, cov tsos mob xws li kiv taub hau, mob taub hau, tsaug zog, thiab coma yuav tshwm sim, thiab hauv qhov xwm txheej hnyav, kev tuag sai sai yuav tshwm sim ncaj qha.
