Qhov ruaj LPG liquefied roj av tswb tswb feem ntau muaj ob ntu: lubLPG leak detectorthiab lub tswb ntsuas roj. Lub tshuab ntes tuaj yeem siv nws tus kheej thiab tuaj yeem nruab nrog lub suab thiab lub tswb nrov thiab ntawm - qhov chaw tso saib ua haujlwm, tab sis nws yuav tsum muaj 24V fais fab mov. Yog tias lub tshuab ntes tau siv ua ke nrog tus maub los, tsuas yog 220V fais fab mov yuav tsum tau.
Hauv kev lag luam, catalytic combustion sensors, vim lawv cov nqi -kev ua tau zoo thiab kev ntseeg tau, yog lub zog tseem ceeb thoob ntiaj teb rau kev soj ntsuam qhov kev pheej hmoo tawg ntawm cov roj hluav taws xob. Catalytic combustion gas sensors ua haujlwm raws li lub hauv paus ntsiab lus thermal effect ntawm catalytic combustion. Nyob rau hauv tej yam kev mob kub, combustible gases undergo flameless combustion nyob rau saum npoo ntawm lub detection ntsiab cab kuj thiab nyob rau hauv qhov kev txiav txim ntawm lub catalyst, outputting ib tug hluav taws xob teeb liab proportional rau lub concentration ntawm combustible gas. Qhov concentration ntawm cov pa taws tuaj yeem paub tau los ntawm kev ntsuas qhov loj ntawm qhov kev hloov pauv ntawm cov hlau platinum. Nws yog tsuas yog siv rau kev tshawb nrhiav cov pa roj carbon monoxide, uas muaj cov kab hluav taws xob zoo ntawm cov khoom siv hluav taws xob, kev ntsuas kev ntseeg tau, tus nqi qis, thiab tsis muaj tus ntoo khaub lig- tawm tsam nrog lwm yam tsis yog - nkev gases.
Lub hauv paus ntsiab lus ua haujlwm tshwj xeeb yog raws li hauv qab no
1. Cua sov thiab ntsuas qhov ntsuas: Ob lub ntsiab lus yog rhuab los ntawm tam sim no mus rau qhov kub thiab txias ntawm kwv yees li 500 degree. Nyob rau hauv cov huab cua ntshiab, tus choj yog nyob rau hauv ib tug balanced lub xeev thiab cov zis teeb liab yog xoom.
2. Catalytic combustion: Thaum combustible gases xws li LPG diffuse mus rau saum npoo ntawm cov khoom kuaj pom, flameless catalytic combustion (oxidation cov tshuaj tiv thaiv) tshwm sim nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst.
3. Thaum tshav kub kub thiab kev hloov pauv: Cov cua kub uas tsim los ntawm kev sib txuas ntxiv nce qhov kub ntawm qhov ntsuas qhov ntsuas (D), uas ua rau muaj qhov nce ntawm qhov tsis kam ntawm nws cov platinum hlau. Qhov tsis kam ntawm cov khoom siv nyiaj (C) tseem tsis hloov pauv vim nws tsis koom nrog cov tshuaj tiv thaiv.
4. Choj imbalance tsim cov teeb liab: Qhov sib npaug ntawm tus choj cuam tshuam, tsim ib millivolt - theem voltage sib txawv teeb liab uas yog linearly proportional rau cov roj concentration.
5. Kev Ua Teeb Meem thiab Tswb: Lub teeb liab tsis muaj zog no tau nthuav dav thiab ua tiav, thiab thaum kawg tso tawm raws li %LEL (feem pua ntawm cov khoom tawg qis dua). Feem ntau, lub tswb qis (20-25% LEL) thiab lub tswb nrov (50% LEL) tau teeb tsa. Thaum cov kev txwv dhau lawm, lub tswb yuav tshwm sim tam sim ntawd.
Lub tswb hluav taws xob hluav taws xob yuav tsum tau muab tso rau hauv qhov chaw xws li cov roj av liquefied roj cia tank cheeb tsam, compressed natural gas storage cylinder room (shed), liquefied petroleum gas or natural gas pump and compressor room (shed) in gas filling stations and together gas filling stations. LPG liquefied roj av tswb tswb yog ib tug roj concentration nrhiav kom tau cov cuab yeej siv los xyuas qhov flammability ntawm LPG liquefied roj av roj. Nws teeb tsa qhov kev tshawb nrhiav ntau yam raws li qhov kev txwv qis qis ntawm LPG liquefied roj av roj thiab siv cov pa ntse ntse rau kev tshawb nrhiav pom. Xyuas kom tus kheej thiab khoom muaj kev nyab xeeb hauv kev tsim khoom.
