Yim hom ntawm cov pa phem tsis tshua muaj zais rau hauv txoj kev tsheb ciav hlau, thiab cov tog neeg tsim kho siv cov khoom siv roj
Gas detectors xyuas kom muaj kev ruaj ntseg kev tsim kho ntawm Hongdoushan Qhov
Nws tau nkag siab tias ntau dua 10,000-meter-ntev Hongdoushan Tunnel yog ib feem tseem ceeb ntawm Tuam Tshoj-Myanmar International Railway, thiab nws tseem yog qhov nyuaj tshaj plaws hauv kev tsim kho ntawm Dalin Railway (Dali rau Lincang) tab tom tsim kho hauv Yunnan.
Hauv qhov av no, thaj chaw txaus ntshai ntawm cov pa phem thiab cov pa phem rau ntau dua 70 feem pua ntawm tag nrho qhov. Cov pa phem thiab cov pa phem muaj nyob hauv cov khoom siv tsis yog thee, uas yog thawj zaug hauv keeb kwm ntawm Tuam Tshoj txoj kev tsheb ciav hlau.
Muaj ntau npaum li 8 hom tshuaj lom thiab teeb meem gases enriched nyob rau hauv lub qhov av no, uas tau tshaj qhov kev txawj ntse ntawm geological kev tshawb fawb, thiab tsis muaj kev paub tab technology.
Nws tau tshaj tawm tias lub qhov dej no tsuas yog cov pa phem nkaus xwb uas tau sau 8 yam tshuaj lom thiab cov pa phem kom deb li deb tau ntsib hauv kev tsim kho tsheb ciav hlau hauv kuv lub tebchaws. Cov pa roj no muaj xws li hydrogen sulfide, carbon monoxide, sulfur dioxide, nitrogen dioxide, thiab lwm yam.
Ntawm lawv, cov pa roj carbon monoxide ntau dhau tuaj yeem ua rau tuag taus thiab tawg, nitrogen dioxide tuaj yeem ua rau lub ntsws ua pa thiab ua rau mob ntsws thiab lwm yam kab mob, hydrogen sulfide tuaj yeem ua rau tuag taus nyob rau lub sijhawm luv luv tom qab nqus pa ...
Kev siv cov tshuaj lom thiab phom sij ntawm cov khoom siv hluav taws xob hauv qhov chaw tsim kho
▲ Tus neeg tsim khoom ua haujlwm nyob rau hauv cov tshuaj lom neeg thiab cov pa phem
Nyob rau hauv no hais txog, lub project tsim tog koom tes nrog universities los ua scientific thiab technologies kev tshawb fawb nyob rau hauv lub ntsiab technologies rau kev tsim kho ntawm lub non-coal series teeb meem roj seem ntawm lub qhov, thiab ua tiav lub tshiab breakthroughs.
Nrog kev pab los ntawm cov cuab yeej siv hluav taws xob zoo tshaj plaws, ntau yam teeb meem roj tsis siv neeg saib xyuas thiab lub tswb thiab cov khoom siv hluav taws xob nqa tau tshwj xeeb tau teeb tsa hauv qhov kev tsim kho kom pom thiab saib xyuas cov pa phem ua ntej, thiab saib xyuas huab cua hauv qhov av tiag tiag. sij hawm.

Kev xaiv cov tshuaj lom thiab phom sij rau cov pa hauv qhov tunnels
Cov pa phem thiab cov pa phem hauv qhov av ib txwm yog qhov tseem ceeb ntawm kev txaus ntshai thaum tsim kho, thiab kev nyab xeeb loj yuav tshwm sim yog tias kev tsim kho tsis raug. Hauv qhov no, cov khoom siv roj saib xyuas raws li ntau yam roj sensor nrhiav tau cov thev naus laus zis los ua ke.
Hauv kev teeb tsa kev lag luam thiab cov txheej txheem tsim khoom, cov khoom siv roj ruaj ruaj tau siv ntau dua.
Lub ntsuas roj ruaj ruaj yog feem ntau yog ob lub cev. Kev soj ntsuam kuaj pom muaj xws li roj sensor thiab transmitter tau teeb tsa rau ntawm qhov chaw kuaj pom tag nrho, thiab cov cuab yeej thib ob uas muaj lub zog hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv lub tswb raug teeb tsa hauv qhov chaw nyab xeeb tag nrho, uas yooj yim rau kev saib xyuas. .
Portable Gas Detector
▲ Portable gas detectors siv nyob rau hauv txawv teb chaws tunnel corridors
Rau qhov nyuaj thiab hnyav qhov chaw ib puag ncig zoo li Hongdoushan Tunnel, portable gas detectors yog qhov kev xaiv zoo tshaj plaws, tshwj xeeb tshaj yog cov khoom siv hluav taws xob sib xyaw ua ke, uas tuaj yeem saib xyuas ntau yam tshuaj lom thiab teeb meem roj tib lub sijhawm, hloov mus rau ntau yam nyuaj lossis hnyav. ib puag ncig.
Nyob rau tib lub sijhawm, los ntawm kev sib txuas lus hauv wireless module, kev sib txuas lus wireless tuaj yeem pom tau hauv cheeb tsam uas muaj cov teeb liab wireless. Thaum cov roj concentration siab tshaj tus qauv, nws yuav ceeb toom tam sim kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
Nyob rau hauv cov kev xaiv tshwj xeeb, vim hais tias cov pa phem nyob rau hauv lub qhov yuav muab faib ua ob pawg: combustible gas thiab toxic gas. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv ib tug haum gas detector rau txawv ntau lawm zaus thiab nrhiav kom tau raws li txoj cai.
Piv txwv li, thaum xaiv ib tug gas detector, yog hais tias muaj feem ntau methane thiab lwm yam tsawg toxic alkanes, nws yog qhov zoo tshaj plaws xaiv los xaiv combustible gas sensor detection khoom;
Txawm li cas los xij, yog tias muaj cov pa phem xws li carbon monoxide (CO) thiab hydrogen sulfide (H2S), cov khoom siv roj tshwj xeeb yuav tsum raug xaiv ua ntej; Xaiv cov khoom siv photoionization (PID);
Yog hais tias qhov saum toj no ntau hom roj av raug them, xaiv cov khoom siv hluav taws xob sib xyaw yuav ua tiav ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog.
