Lub tshuab ntes roj CH4, O2, CO, H2S uas nqa tau ntau lub CD4
Cov ntawv thov
Lub tshuab ntsuas roj ntau CD4 uas nqa tau yooj yim yog ib lub cuab yeej muaj kev nyab xeeb thiab tsis tawg thiab nws tsim los tiv thaiv cov pa roj. Nws tuaj yeem saib xyuas plaub qhov teeb meem huab cua tib lub sijhawm suav nrog carbon monoxide (CO), oxygen (O2), roj kub hnyiab (%LEL), thiab hydrogen sulphide (H2S). Lub tshuab ntsuas roj ntau CD4 uas me me thiab tsis hnyav ua rau lub tswb ceeb toom hnov, pom thiab co thaum muaj xwm txheej ceeb toom qis lossis siab.
Lub tshuab ntes roj CD4 uas nqa tau ntau yam tsis muaj qhov sib piv hauv nws qhov kev siv tau yooj yim, muaj peev xwm thiab tus nqi tag nrho. Cov kab ntawm cov tshuab ntes roj uas tsis ntub dej tau hloov pauv kev ua lag luam nrog nws cov yam ntxwv zoo sib xws.
Nws yog siv rau ntawm qhov chaw khawb thee hauv av thiab kev tshuaj xyuas kev nyab xeeb ntawm qhov chaw khawb. Tseeb tiag, nws kuj siv rau kev tua hluav taws, qhov chaw kaw, kev lag luam tshuaj lom neeg, roj thiab txhua yam ib puag ncig uas xav tau los ntsuas cov pa roj txaus ntshai thiab lom.
Qauv
CD4 siv txoj kev kuaj kab mob sib kis ntuj. Tus nqi ntsuas tau qhia ua feem pua ntawm peb
kev nyeem ntawv zoo uas tuaj yeem tso saib tus nqi zoo lossis tsis zoo. Kev daws teeb meem feem CH4 tsis tsawg dua 0.01%,
oxygen 0.1% O2, H2S 1 x 10-6 thiab CO 1 x 10-6. Nws yog nrog lub suab thiab lub teeb ceeb toom thiab lub tswb tus kheej-kev kuaj xyuas kev ua haujlwm. Thaum
txwv ntawm cov methane concentration hla qhov ntsuas ntau yam, ntsuas ntsuas muaj lub luag haujlwm ntawm kev tiv thaiv
cov khoom siv catalytic, thiab khaws cov cim qhia ntawm tus neeg sim ua haujlwm dhau
