Lub tshuab kuaj pom roj tuaj yeem kuaj pom 1-6 hom roj teeb meem tib lub sijhawm, suav nrog ammonia, nitrogen, phosgene, hydrogen fluoride thiab lwm yam roj ntsha uas ua rau khaus qhov muag thiab ua pa mucosa, thiab ua rau cov pa roj asphyxiating hauv lub cev. tsis muaj oxygen, xws li nitrogen, methane, ethane, carbon monoxide thiab lwm yam gases. Cov pa roj no ntau dua los yog tsawg dua ua rau tib neeg lub cev lossis ib puag ncig, thiab cov khoom siv roj yuav tsum tau ua kom muaj kev nyab xeeb hauv qhov chaw thiab qhov chaw uas cov pa phem tuaj yeem tshwm sim.
Cov pa phem uas tsom los ntawm kev lag luam txawv txawv. Thaum cov roj rho tawm, tej zaum yuav muaj cov pa phem xws li hydrogen sulfide, carbon monoxide, thiab nitrogen. Nws yog ib qho tsim nyog yuav tsum tau nruab ib lub tshuab ntsuas roj thaum lub sij hawm rho tawm kom zoo tiv thaiv kev sib tsoo los ntawm cov pa tawm. Nyob rau hauv refineries, chaw nres tsheb roj, roj av hloov chaw thiab lwm qhov chaw, nws tseem yuav tsum tau xyuas seb puas muaj roj thiab roj to. Gas detectors kuj feem ntau siv nyob rau hauv kev lag luam teb, vim hais tias feem ntau ntawm raw cov ntaub ntawv thiab intermediates siv nyob rau hauv kev lag luam kws tshuaj yog tshuaj lom thiab teeb meem tshuaj. Gas detectors yuav tsum tau nyob rau hauv cov chaw uas cov tshuaj no yog khaws cia, tsim thiab ua kom paub tseeb tias cov neeg ua hauj lwm thiab kev nyab xeeb ntawm ib puag ncig.
Gas detectors tseem xav tau hauv kev lag luam ua zaub mov. Nitrogen, oxygen, carbon dioxide thiab lwm yam gases yog siv rau hauv cov zaub mov kom tsis muaj menyuam thiab ua haujlwm tshiab. Thaum lub sij hawm tus txheej txheem no, cov concentration ntawm cov gases kuj yuav tsum tau kuaj kom tsis txhob muaj roj to. Methyl bromide, sulfuryl fluoride, propylene oxide thiab lwm yam fumigant gases yuav tsum tau ua kom tsis muaj zaub mov, pub, txuj lom, khoom siv kho mob, cov khoom siv tshuaj pleev ib ce, thiab lwm yam. Cov roj no muaj qee yam kev puas tsuaj rau tib neeg lub cev, thiab yuav tsum muaj cov khoom siv roj; Cov chaw nres nkoj kev lis kev cai Cov neeg khiav dej num kuj yuav tsum tau kuaj xyuas cov roj fumigan residual.
Raws li cov cuab yeej muaj kev nyab xeeb, lub ntsuas roj teeb meem feem ntau ua lub luag haujlwm ceeb toom ntxov thiab haum rau ntau lub sijhawm. Ib qho yog siv rau cov kav xa hluav taws xob thiab chaw cia khoom. Thaum muaj qhov xau tshwm sim, lub ntsuas roj tuaj yeem muab lub tswb. Qhov no yog qhov kev ua haujlwm tshaj plaws ntawm lub tshuab ntsuas roj, thiab lub tshuab hluav taws xob ruaj khov hauv online feem ntau yog siv; Qhov thib ob yog thaum cov neeg ua haujlwm nkag mus rau qhov chaw txwv Kev Ua Haujlwm hauv cov chaw lossis cov khoom siv, xws li cov kav dej, cov khoom siv biogas, cov tso tsheb hlau luam fermentation, thiab lwm yam., txhawm rau txheeb xyuas seb cov pa phem puas dhau tus qauv. Hauv qhov xwm txheej no, feem ntau siv lub twj tso kua mis-suction gas detector; qhov thib peb yog txhawm rau txheeb xyuas cov pa roj uas tsis zoo tom qab siv cov khoom siv tu, tshwj xeeb tshaj yog siv rau kev tshawb nrhiav ua ntej hluav taws; qhov thib plaub yog siv rau kev tshuaj xyuas xwm txheej ceev thiab kev nyab xeeb. Thaum muaj xwm txheej txawv txav tshwm sim lossis raug xwm txheej txawv txav, cov pa phem yuav tsum raug kuaj kom muaj kev nyab xeeb thiab huv.
Xi'an Huafan Technology Co., Ltd. tuaj yeem muab rau kojHandheld Multi Gas Detector, uas siv high-precision thiab ceev-teb sensors, peb lub tswb, thiab ntau lub gases tuaj yeem hloov kho. CE thiab ATEX tau ntawv pov thawj, dav siv hauv tshuaj, mining, roj thiab roj sectors, tunnels, refineries, tanneries, thiab lwm yam.
