Cov lus qhia rau kev yuav khoom siv roj av
1) Paub meej tias hom thiab concentration ntau ntawm cov roj yuav tsum tau kuaj:
Cov hom gases ntsib los ntawm txhua lub tuam tsev tsim khoom sib txawv. Thaum xaiv lub ntsuas roj, nws yog ib qho tseem ceeb uas yuav tau xav txog txhua yam ua tau. Yog tias methane thiab lwm yam tshuaj lom alkanes tseem ceeb tshaj plaws, xaiv qhov ntsuas LEL yog qhov kev xaiv tsim nyog tshaj plaws. Qhov no tsis yog tsuas yog vim LEL detector muaj lub hauv paus ntsiab lus yooj yim thiab daim ntawv thov dav, tab sis kuj 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, qhov tseem ceeb yuav tsum tau muab rau kev xaiv cov khoom siv roj tshwj xeeb kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Yog hais tias muaj ntau cov organic toxic thiab teeb meem gases, xav txog qhov tsawg concentration uas yuav ua rau tus kheej lom, xws li Aromatic hydrocarbon, halogenated hydrocarbon, ammonia (amine), ether, cawv, roj, thiab lwm yam, koj yuav tsum xaiv lub Photoionization detector qhia nyob rau hauv. tshooj dhau los, tsis yog lub ntsuas LEL, vim nws tuaj yeem ua rau raug mob. Yog tias cov roj gases npog cov pawg saum toj no, xaiv cov khoom siv hluav taws xob sib xyaw yuav ua tiav ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog.
2) Txheeb xyuas qhov xwm txheej siv:
Kev xaiv cov khoom siv roj av txawv nyob ntawm qhov chaw ua haujlwm.
A) Tsau roj ntes:
Qhov no yog ib qho khoom siv feem ntau siv hauv kev tsim khoom thiab kev tsim khoom. Nws tuaj yeem ntsia tau rau ntawm cov ntsiab lus tshwj xeeb txhawm rau txheeb xyuas cov pa paug tshwj xeeb. Lub Yiyang ruaj khov ntes yog feem ntau yog ob lub cev, nrog lub taub hau kuaj pom muaj li ntawm lub sensor thiab kis tau tus mob nruab rau ntawm qhov chaw kuaj pom. Cov cuab yeej thib ob uas muaj lub voj voog, lub zog hluav taws xob, thiab cov khoom siv ceeb toom tau teeb tsa rau hauv qhov chaw pej xeem kom yooj yim saib xyuas. Nws txoj kev tshawb nrhiav yog tib yam li tau piav qhia nyob rau hauv ntu dhau los, tab sis nws yog qhov tsim nyog rau kev ruaj ntseg txuas ntxiv mus ntev thiab lwm yam uas yuav tsum tau muaj rau kev tshawb nrhiav ruaj khov ntawm cov txheej txheem thiab thev naus laus zis. Lawv kuj yuav tsum tau xaiv raws li hom thiab concentration ntawm cov pa roj nyob rau hauv qhov chaw, thiab yuav tsum tau them nyiaj mloog mus rau kev txhim kho lawv nyob rau hauv tej qhov chaw uas muaj roj to tshwm sim, xws li xaiv qhov siab tshaj plaws zoo rau kev teeb tsa sensor raws li qhov tshwj xeeb lub ntiajteb txawj nqus. gas, thiab lwm yam.
B) Portable Gas Detector:
Raws li cov cuab yeej portable yog ib qho yooj yim rau kev khiav lag luam thiab compact, nws tuaj yeem nqa mus rau ntau qhov chaw sib txawv. Lub roj teeb Alkaline yog siv rau kev siv hluav taws xob, thiab nws tuaj yeem siv tsis tu ncua rau 1000 teev; Cov tshiab LEL detectors, PID, thiab cov cuab yeej sib xyaw siv cov roj teeb uas siv tau (qee tus twb tau siv cov roj teeb tsis nco qab nickel hydrogen lossis lithium-ion roj teeb), ua rau lawv feem ntau tuaj yeem ua haujlwm tsis tu ncua rau ze li 12 teev. Yog li ntawd, lawv cov ntawv thov nyob rau hauv ntau lub chaw tsim khoom thiab chaw saib xyuas kev noj qab haus huv tau dhau los ua ntau dua.
C) Composite gas detector
Lub tshuab hluav taws xob sib xyaw ua ke tuaj yeem nruab nrog ntau lub tshuab ntsuas roj uas xav tau ntawm ib qho cuab yeej, yog li nws muaj cov yam ntxwv ntawm cov ntim me me, lub teeb yuag, cov lus teb ceev ceev, thiab cov khoom siv ib txhij ntawm cov roj ntau ntau. Qhov tseem ceeb tshaj, tus nqi ntawm Yiyang composite multi gas detector yog pheej yig dua li ntawm ntau lub diffusion gas detectors, thiab nws kuj yooj yim dua rau siv. Nws yuav tsum tau muab sau tseg tias thaum xaiv hom kev ntes no, nws yog qhov zoo tshaj plaws los xaiv ib qho cuab yeej nrog cov kev hloov pauv cais rau txhua lub sensor kom tsis txhob muaj kev puas tsuaj rau ib lub sensor los ntawm kev cuam tshuam rau kev siv lwm yam sensors. Cov cuab yeej ntsuas roj feem ntau siv nyob rau hauv ib puag ncig uas muaj cov pa phem tuaj yeem tsim thiab ua rau muaj kev hem thawj rau kev nyab xeeb ntawm tus kheej lossis yuav ua rau muaj qhov tshwm sim. Thiab cov cuab yeej ntsuas roj yog qhov tseem ceeb rau kev tiv thaiv ntxov ntawm ib puag ncig muaj kuab paug thiab ua kom muaj kev nyab xeeb ntawm tib neeg lub neej.
