Tej yam yuav tsum tau txiav txim siab nyob rau hauv kev xaiv ntawm Multi-gas Detectors thiab Technical Communication
1. Paub meej tias hom thiab concentration ntau ntawm cov roj yuav raug kuaj pom:
Cov hom gases ntsib los ntawm txhua lub tuam tsev tsim khoom sib txawv. Thaum xaiv lub ntsuas roj, txhua qhov xwm txheej yuav tsum tau txiav txim siab. Yog tias methane thiab lwm yam tshuaj lom hydrocarbons yog qhov tseem ceeb, xaiv qhov ntsuas LEL yog qhov tsim nyog dua. Qhov no tsis yog vim hais tias lub hauv paus ntsiab lus ntawm LEL ntes tau yooj yim thiab dav siv, tab sis kuj vim nws muaj cov yam ntxwv ntawm kev saib xyuas yooj yim thiab calibration. Yog tias muaj cov pa phem xws li cov pa roj carbon monoxide thiab hydrogen sulfide, nws yog ib qho tsim nyog yuav tsum tau ua qhov tseem ceeb ntawm kev siv lub tshuab ntsuas roj los xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Yog tias muaj cov pa roj carbon monoxide ntau dua thiab muaj kev phom sij, xav txog lawv qhov tsis tshua muaj siab uas yuav ua rau muaj kev phom sij rau cov neeg ua haujlwm, xws li cov pa roj carbon monoxide, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, lipids, thiab lwm yam, yuav tsum xaiv lub photoionization detector es tsis txhob siv LEL detector, vim qhov no yuav ua rau cov neeg raug mob.
2. Txiav txim siab qhov kev siv scenario:
Raws li kev lag luam ib puag ncig sib txawv, peb tuaj yeem faib cov khoom siv roj rau hauv peb hom: cov khoom siv hluav taws xob ruaj khov, cov khoom siv hluav taws xob portable, thiab cov khoom siv roj sib xyaw. Ntawm lawv:
1) Tsau roj ntes: Cov roj av ruaj khov tuaj yeem ntsia tau rau ntawm cov ntsiab lus tshawb pom tshwj xeeb kom pom cov pa paug tshwj xeeb. Lawv feem ntau yog ob-thooj, nrog lub taub hau kuaj pom muaj li ntawm cov sensors thiab transmitters ntsia tag nrho ntawm qhov chaw kuaj pom, thiab cov cuab yeej thib ob uas muaj cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv ceeb toom tau teeb tsa tag nrho hauv qhov chaw nyab xeeb rau kev saib xyuas yooj yim.
2) Portable gas detector: Portable gas detectors muaj qhov zoo ntawm kev ua haujlwm yooj yim, compact loj, thiab tuaj yeem nqa mus rau qhov chaw sib txawv. Yog siv nyob rau hauv qhov chaw qhib xws li qhib kev cob qhia raws li kev ceeb toom kev nyab xeeb, portable diffusion gas detectors yuav siv tau vim hais tias lawv muaj peev xwm tsis tu ncua, real-time, thiab meej tso saib cov concentration ntawm cov tshuaj lom thiab teeb meem gases ntawm qhov chaw; Yog tias nkag mus rau hauv qhov chaw kaw, xws li cov tshuaj tiv thaiv tank, cov tso tsheb hlau luam lossis cov thawv ntim khoom, cov kav dej hauv av lossis lwm cov kav dej hauv av, cov chaw hauv av, cov chaw ua liaj ua teb, cov tsev khaws khoom noj, cov tsheb ciav hlau, cov tsheb thauj khoom thauj khoom, cov tunnels, thiab lwm yam.
3) Composite Gas Detector: Lub tshuab hluav taws xob sib xyaw tuaj yeem nruab nrog ntau lub ntsuas roj ntsuas ntawm ib lub twj paj nruag, yog li nws muaj cov yam ntxwv ntawm qhov me me, lub teeb yuag, cov lus teb ceev ceev, thiab cov khoom siv ib txhij ntawm ntau cov pa roj. Piv nrog rau cov khoom siv hluav taws xob dav dav, nws kuj siv tau yooj yim dua.
