Yuav ua li cas xaiv lub ntsuas roj rau cov pa phem thiab phom sij
Cov roj hom thiab cov concentration ntau yuav tsum tau kuaj pom: Thaum xaiv lub ntsuas roj, txhua qhov xwm txheej yuav tsum tau txiav txim siab. Yog tias methane thiab lwm yam tshuaj lom alkanes feem ntau, nws yog qhov tsim nyog tshaj plaws los xaiv lub ntsuas LEL. Qhov no tsis yog tsuas yog vim LEL Lub tshuab ntes tau yooj yim hauv txoj cai thiab siv dav, thiab nws kuj muaj cov yam ntxwv ntawm kev saib xyuas yooj yim thiab ntsuas. Yog tias muaj cov pa phem xws li cov pa roj carbon monoxide thiab hydrogen sulfide, nws yog ib qho tsim nyog yuav tsum xaiv lub tshuab kuaj roj tshwj xeeb ua ntej kom muaj kev nyab xeeb. Yog tias cov pa roj carbon monoxide ntau dua thiab muaj kev phom sij, xav tias lawv yuav ua rau cov neeg ua haujlwm thiab cov pa phem tsawg, xws li cov pa roj carbon monoxide, cawv, ammonia, ethers, rog, thiab lwm yam, koj yuav tsum xaiv cov khoom siv photoionization es tsis txhob LEL detectors. Vim nws yuav ua rau muaj kev phom sij rau cov neeg ua haujlwm lub neej.
Txiav txim seb yuav siv qhov twg:
Cov kev lag luam sib txawv yuav tsum muaj ntau hom roj ntes.
Portable Gas Detector:
Cov cuab yeej portable yog ib qho yooj yim rau kev khiav lag luam, me me, thiab tuaj yeem nqa mus rau ntau qhov chaw sib txawv. Lub electrochemical detector yog siv los ntawm cov roj teeb thiab tuaj yeem siv tsis tu ncua. Hydrogen lossis carp ion roj teeb), yog li lawv tuaj yeem ua haujlwm tsis tu ncua li 1 hnub.
Yog tias cov cuab yeej no siv los ua kev ceeb toom kev nyab xeeb nyob rau hauv qhov chaw qhib, xws li qhib kev cob qhia, lub tshuab hluav taws xob xa hluav taws xob tuaj yeem siv tau, vim tias nws tuaj yeem ua haujlwm tsis tu ncua, lub sijhawm tiag tiag, thiab ua kom pom tseeb ntawm cov pa phem thiab cov pa phem. ntawm qhov chaw. Qhov no yog qee cov cuab yeej tshiab ntawm chav kawm no kuj tau nruab nrog cov khoom siv vibration tswb kom tsis txhob hnov qab tsis hnov tsw suab nrov hauv ib puag ncig tsis zoo, thiab teeb tsa lub khoos phis tawj los sau cov ncov, STEL (15-feeb luv luv-term raug) thiab TWA ( 8- teev qhov ntsuas qhov hnyav nruab nrab) Muab cov lus qhia tshwj xeeb rau cov neeg ua haujlwm noj qab haus huv thiab kev nyab xeeb.
Yog tias nkag mus rau hauv qhov chaw kaw, xws li cov tshuaj tiv thaiv tank, 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 airtight granaries, tsheb ciav hlau tsheb, tsheb thauj khoom thauj khoom, qhov av thiab lwm qhov chaw ua haujlwm, kev tshuaj xyuas yuav tsum tau ua ua ntej cov neeg ua haujlwm nkag. , thiab kev tshawb nrhiav yuav tsum tau nqa tawm sab nraum qhov chaw kaw. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum xaiv lub tshuab hluav taws xob ntau [Industrial Electrical Network-cnelc] detector nrog lub twj tso kua mis ua qauv. Vim tias cov roj faib rau hauv qhov sib txawv (sab sauv, nruab nrab thiab qis) hauv qhov chaw kaw nws txawv ntawm hom roj. Piv txwv li: qhov kev faib ua feem ntawm combustible gases nyob rau hauv lub general kev txiav txim zoo yog lub teeb, thiab lawv feem ntau yog faib nyob rau hauv tej qhov chaw. Lub ntiajteb txawj nqus tshwj xeeb ntawm carbon monoxide zoo ib yam li huab cua. Cov pa hnyav dua xws li hydrogen muaj nyob hauv qis ntawm qhov chaw kaw. Nyob rau tib lub sijhawm, cov pa oxygen concentration kuj yog ib yam uas yuav tsum tau kuaj pom. Tsis tas li ntawd, yog hais tias qhov ua tau volatilization thiab to ntawm cov organic tshuaj nyob rau hauv lub tank raug txiav txim siab, ib tug detector uas yuav ntes tau cov organic gases kuj yuav tsum tau. Yog li ntawd, ib tug ua tiav gas detector nyob rau hauv ib tug confined qhov chaw yuav tsum muaj ib tug built-in twj tso kua mis muaj nuj nqi rau cov uas tsis yog-sib cuag, sub-site nrhiav kom tau thiab ib tug multi-gas detection muaj nuj nqi mus ntes cov roj txaus ntshai faib nyob rau hauv ntau qhov chaw, xws li inorganic gases thiab organic gases. Oxygen detection muaj nuj nqi tiv thaiv hypoxia los yog enrichment. Nws yog ib qho khoom siv portable uas me me thiab tsis cuam tshuam rau kev ua haujlwm ntawm cov neeg ua haujlwm. Tsuas yog nyob rau hauv txoj kev no tuaj yeem lav qhov kev nyab xeeb ntawm cov neeg ua haujlwm nkag mus rau qhov chaw kaw.
Tsis tas li ntawd, tom qab nkag mus rau hauv qhov chaw kaw, cov roj muaj pes tsawg leeg hauv nws yuav tsum tau kuaj kom tsis tu ncua kom tsis txhob muaj kev hloov pauv hauv cov ntsiab lus ntawm cov organic tebchaw los yog lwm cov pa phem thiab cov pa phem vim yog cov neeg ua haujlwm nkag, tam sim ntawd to, thiab kub hloov.
Yog tias nws yog siv rau kev sib tsoo thaum muaj xwm txheej ceev, nrhiav kom pom thiab tshuaj xyuas, nws yuav tsum siv lub tshuab nqus tsev twj tso kua mis, lub sij hawm teb luv luv, siab rhiab heev thiab kev daws teeb meem, kom nws yooj yim los txiav txim qhov chaw ntawm qhov xau.
Taag gas detection raws tu qauv:
Qhov no yog ib tug detector uas yog dav siv nyob rau hauv industrial cov khoom thiab ntau lawm txheej txheem. Nws tuaj yeem ntsia tau rau ntawm cov ntsiab lus tshwj xeeb txhawm rau txheeb xyuas cov pa paug tshwj xeeb. Tsau detectors feem ntau yog ob-lub cev, muaj xws li sensors thiab transmitters Lub taub hau nrhiav tau raug ntsia rau ntawm qhov chaw kuaj pom tag nrho, thiab nws yog ib qho khoom siv thib ob uas muaj cov khoom siv hluav taws xob, hluav taws xob thiab cov khoom siv tswb.
Nws yog ntsia rau hauv ib qho chaw nyab xeeb tag nrho thiab yooj yim rau kev saib xyuas. Nws lub hauv paus ntsiab lus tshawb nrhiav yog tib yam li tau piav qhia hauv ntu dhau los, tab sis nws yog qhov tsim nyog rau kev ruaj ntseg txuas ntxiv thiab mus ntev uas yuav tsum tau ua los ntawm kev tshawb nrhiav ruaj khov ntawm cov txheej txheem thiab thev naus laus zis. Lawv kuj yuav tsum tau ua raws li hom roj av ntawm qhov chaw. Nyob rau tib lub sijhawm, peb kuj yuav tsum tau them sai sai rau kev txhim kho lawv nyob rau hauv feem ntau yuav xau qhov chaw ntawm cov gases tshwj xeeb, xws li xaiv qhov zoo tshaj plaws qhov siab ntawm sensor installation raws li lub ntiajteb txawj nqus ntawm cov roj, thiab lwm yam.
