Kev txiav txim siab tseem ceeb rau kev ua haujlwm kom raug, kev tu thiab kev pabcuam ntawm cov khoom siv roj
Lub tswb hluav taws xob hluav taws xob muaj lub ntsuas hluav taws xob thiab lub tswb nrov, siv dav hauv kev lag luam petrochemical uas muaj cov roj hluav taws xob, xws li roj, roj, tshuaj, thiab roj depots. Nws yog siv los txheeb xyuas cov dej xau hauv qhov chaw muaj kev phom sij hauv tsev thiab sab nraum zoov thiab yog ib qho cuab yeej tseem ceeb los xyuas kom meej tias kev tsim khoom thiab kev nyab xeeb ntawm tus kheej. Thaum muaj roj combustible nyob rau hauv qhov chaw kuaj, lub detector converts cov roj teeb liab mus rau ib tug voltage teeb liab los yog ib tug tam sim no teeb liab thiab xa mus rau lub tswb ntsuas, uas qhia cov feem pua concentration tus nqi ntawm qhov tsawg explosive txwv ntawm cov combustible gas. Thaum lub concentration ntawm cov roj combustible ntau tshaj lub tswb ceeb toom tus nqi, ib tug audible thiab pom lub tswb ceeb toom yuav tshwm sim, thiab cov neeg ua hauj lwm nyob rau hauv lub luag hauj lwm yuav siv sij hawm kev ruaj ntseg ntsuas kom tsis txhob muaj xwm txheej tawg. Thaum lub tswb nrov roj combustible yog ntsia rau hauv qhov chaw, nws txoj hauj lwm tsis yooj yim hloov. Raws li kev ua haujlwm ntau xyoo dhau los, cov ntsiab lus hauv qab no yuav tsum tau txiav txim siab thaum siv cov roj ntsuas kom raug rau cov ntawv thov tshwj xeeb.
(1) Txheeb xyuas qhov muaj peev xwm xau cov ntsiab lus ntawm cov cuab yeej yuav tsum tau saib xyuas, txheeb xyuas cov yam ntxwv xws li kev xau siab thiab kev taw qhia, thiab kos daim ntawv qhia kev faib tawm ntawm txoj haujlwm sojntsuam. Muab cov cuab yeej faib ua peb theem raws li qhov hnyav ntawm qhov xau: Qib I, Qib II, thiab Qib III.
(2) Raws li cov yam ntxwv tshwj xeeb xws li airflow kev taw qhia thiab cua kev taw qhia nyob rau hauv qhov chaw, txiav txim siab cov kev taw qhia ntawm combustible gas leakage thaum muaj ib tug loj npaum li cas ntawm to.
(3) Raws li qhov ceev ntawm cov pa xau (ntau dua lossis tsawg dua huab cua), ua ke nrog qhov sib txawv ntawm cov huab cua ntws, ib daim ntawv qhia peb-dimensional flow trend of the leak is synthesized, and an initial setting plan is made at the downstream position of its flow.
(4) Tshawb xyuas seb qhov dej xau ntawm qhov taw tes yog micro to lossis dav hlau zoo li. Yog tias nws yog me me, qhov chaw ntawm qhov taw tes yuav tsum nyob ze rau ntawm qhov xau. Yog tias nws yog lub dav hlau xau, nws yuav tsum tau khaws me ntsis deb ntawm qhov xau. Raws li cov xwm txheej no, tsim cov phiaj xwm kev teeb tsa zaum kawg. Ua li no, qhov ntau thiab ntau yam uas yuav tsum tau yuav khoom tuaj yeem kwv yees.
(5) Rau qhov chaw uas muaj cov pa hluav taws xob tseem ceeb, qhov ntsuas pom yuav tsum tau teeb tsa txhua 10-20m raws li cov kev cai cuam tshuam. Rau cov chav tsev me me thiab cov twj tso kua mis tsis tu ncua, kev saib xyuas yuav tsum tau them rau qhov muaj peev xwm ntawm cov pa roj combustible, thiab lub tshuab nqus tsev feem ntau yuav tsum tau nruab rau ntawm qhov hluav taws xob qis.
(6) Rau qhov chaw uas muaj cov pa tawm hydrogen, cov cuab yeej kuaj xyuas yuav tsum tau nruab rau ntawm qhov chaw tiaj tus saum qhov chaw xau.
(7) Rau kev tshaj tawm nrog cov pa roj ntau dua li huab cua, lub tshuab ntes yuav tsum tau nruab rau ntawm lub dav hlau hauv qab ntawm qhov to, thiab yuav tsum tau them nyiaj rau cov yam ntxwv ntawm ib puag ncig. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov teeb tsa ntawm kev saib xyuas kev nyab xeeb hauv cov chaw uas cov roj hluav taws xob tuaj yeem tuaj yeem tsim tau.
(8) Rau qhov chaw qhib qhov chaw uas cov roj hluav taws xob tau tawg thiab khiav tawm, yog tias tsis muaj qhov cua zoo, nws kuj yog ib qho yooj yim rau cov roj combustible nyob rau hauv ib feem ntawm cov huab cua mus kom ze los yog ncav cuag qhov tsawg kawg nkaus txwv concentration. Cov no yog cov ntsiab lus tseem ceeb ntawm kev saib xyuas kev nyab xeeb uas tsis tuaj yeem tsis quav ntsej.
Kev siv lub tswb ceeb toom tsis yog tsuas yog ua kom koj ua tiav koj txoj haujlwm zoo, tab sis kuj tseem muab qee qhov lav rau koj lub neej!
