Dab tsi ntawm gases muaj nyob rau hauv cov pa plaub-hauv-ib gas detector?
1. Cov nqi sib txawv ntawm qhov sib txawv ntawm cov pa roj methane combustible
1. Thaum methane (CH4) siab tshaj 1.00 feem pua, lub ntsuas roj yuav tswb;
2. Thaum tus nqi ntawm methane (CH4) ntawm lub ntsuas ntsuas qis dua 1.00 feem pua, nws yog qhov qub;
3. Thaum tus nqi ntawm methane (CH4) ntawm lub tshuab ntes tau tshaj 5 feem pua, muaj kev phom sij ntawm kev tawg thaum raug teeb, thiab hluav taws xob vuam txwv tsis pub;
4. Yog tias tus nqi methane (CH4) ntawm lub ntsuas ntsuas siab tshaj 25 feem pua, nws tuaj yeem ua rau mob taub hau, kiv taub hau, qaug zog, tsis muaj zog, ua pa nrawm thiab lub plawv dhia, thiab koj yuav tsum tawm mus rau sab nraud rau qhov cua txhua 30 feeb los yog li ntawd.
2. Cov nqi sib txawv ntawm qhov sib txawv ntawm cov pa roj carbon monoxide
1. Thaum cov pa roj carbon monoxide (CO) siab tshaj 24ppm, lub ntsuas roj yuav ceeb toom;
2. Thaum cov pa roj carbon monoxide (CO) ntawm lub tshuab ntes tau tshaj 50 teev tsaus ntuj, nws yog cov ntsiab lus siab tshaj plaws pub rau cov neeg laus nyob hauv nws;
3. Thaum cov pa roj carbon monoxide (CO) ntawm lub ntsuas ntsuas siab tshaj 200ppm, tom qab (2-3) teev, yuav muaj mob taub hau me ntsis, kiv taub hau, thiab muaj kev khuv leej, thiab koj yuav tsum tawm mus rau sab nraum cua txhua 30 feeb lossis li ntawd;
4. Thaum cov pa roj carbon monoxide (CO) ntawm lub ntsuas ntsuas siab tshaj 400ppm, tawm ntawm qhov chaw tam sim ntawd thiab ceeb toom rau tus neeg saib xyuas.
3. Tus nqi sib txawv ntawm qhov sib txawv ntawm cov pa oxygen
1. Thaum cov pa oxygen (02) qis dua 18.0 feem pua, lub ntsuas roj yuav tswb;
2. Cov pa roj (O2) tus nqi ntawm lub ntes yog 20.9 feem pua, uas yog cov ntsiab lus ntawm cov pa oxygen hauv huab cua;
3. Thaum tus nqi oxygen (O2) ntawm lub ntsuas ntsuas qis dua 15 feem pua, tib neeg yuav ua tsis taus pa luv, mob taub hau, kiv taub hau, qaug zog thiab tsis muaj zog, thiab qeeb qeeb. Tam sim ntawd tawm ntawm qhov chaw thiab ceeb toom rau tus neeg saib xyuas.
4. Cov nqi sib txawv ntawm qhov sib txawv ntawm hydrogen sulfide
1. Thaum hydrogen sulfide (H2S) tshaj 10ppm, lub ntsuas roj yuav tswb;
2. Thaum cov hydrogen sulfide (H2S) ntawm lub ntsuas ntsuas yog 50ppm–100pa, muaj ntxhiab tsw ntxhiab, thiab nws yuav tsum tau tso cua tawm sab nraud txhua 30 feeb lossis li ntawd;
3. Thaum cov hydrogen sulfide (H2S) ntawm lub ntsuas ntsuas yog 100ppm-200pm, qhov hnov tsw tsw yog tuag tes tuag taw, tam sim ntawd tawm ntawm qhov chaw thiab ceeb toom rau tus neeg saib xyuas;
4. Thaum cov hydrogen sulfide (H2S) ntawm lub ntsuas ntsuas tshaj 200 teev tsaus ntuj, nws yuav raug tshuaj lom nyob rau hauv ib teev, tawm ntawm qhov chaw tam sim ntawd thiab ceeb toom rau tus neeg saib xyuas.
Cov pa hluav taws xob plaub-hauv-ib lub ntsuas hluav taws xob (cov khoom siv hluav taws xob sib xyaw) yog siv dav hauv petrochemical, pleev xim, hluav taws xob fais fab, metallurgy, kev tiv thaiv ib puag ncig, papermaking thiab lwm yam kev lag luam. Thaum kuaj pom qhov concentration ntawm roj nyob rau hauv ib puag ncig kom ncav cuag tus nqi tswb preset, cov pa ib tug 4-hauv-1 gas detector yuav xa tawm suab, lub teeb thiab vibration tswb.
