1. Hais txog H2:
Hydrogen yog cov pa roj uas tsis muaj tshuaj lom, tab sis nws yog nplaim taws, tawg thiab ua tsis taus pa. Yog tias muaj lub suab nrov nrov thaum hlawv, nws txhais tau hais tias cov pa roj hydrogen tsis huv thiab tuaj yeem tawg tau yooj yim. Hydrogen yog lub teeb pom kev zoo tshaj plaws hauv ntiaj teb. Txhawm rau kuaj xyuas hydrogen concentration, siv lub ntsuas dej hydrogen. Nyob ntawm qhov xwm txheej, lub tshuab nqus dej twj tso kua mis lossis lub ntsuas hluav taws xob ruaj khov tuaj yeem xaiv tau yooj yim. Vim tias qhov flammability ntawm hydrogen, lub tshuab hluav taws xob hluav taws xob kuj tseem siv tau los kuaj xyuas qhov flammability ntawm hydrogen.
Hydrogen tuaj yeem hlawv thaum lub ntim feem hauv huab cua yog 4% txog 75%. Hydrogen yog cov pa roj ntau heev thaum sib xyaw nrog huab cua ntawm qhov concentration ntawm 4% mus rau 74%, los yog tov nrog cov tshuaj chlorine ntawm qhov concentration ntawm 5% mus rau 95%, thiab tuaj yeem yooj yim detonate nyob rau hauv stimulation ntawm tshav kub, tshav ntuj los yog sparks. Hydrogen tsis yog reactive heev nyob rau hauv ib txwm tej yam kev mob, tab sis hydrogen forms tebchaw nrog feem ntau cov ntsiab lus. Muaj ntau lab tus paub txog hydrocarbons, tab sis lawv tsis yog tsim los ntawm kev sib txuas ncaj qha ntawm hydrogen thiab carbon. Hydrogen reacts nrog ntau electronegative ntsiab xws li halogens.
2.Hydrogen hluav taws kub ceev teb
Ceev nrooj khiav tawm cov neeg ua haujlwm nyob rau hauv qhov chaw paug paug mus rau qhov chaw nce siab thiab cais lawv kom nruj kev nkag mus. Txiav tawm qhov hluav taws kub. Nws raug pom zoo tias cov neeg ua haujlwm thaum muaj xwm txheej ceev yuav hnav lub tshuab ua pa zoo rau tus kheej thiab cov khaub ncaws tiv thaiv hluav taws. Kev ua pa kom zoo nrawm nrawm. Yog tias ua tau, siv lub tshuab tso pa tawm kom xa cov pa tawm mus rau qhov chaw qhib lossis nruab qhov tsim nyog nozzles los hlawv nws. Cov thawv ntim yuav tsum tau kho kom zoo thiab tshuaj xyuas ua ntej siv. Tsis txhob tua hluav taws kub yog tias qhov hluav taws xob tsis tuaj yeem txiav tawm tam sim ntawd. Txias lub thawv nrog dej txau. Yog tias ua tau, txav lub thawv los ntawm qhov chaw tua hluav taws mus rau qhov chaw qhib. Cov hluav taws tua hluav taws tawm cov dej tsis huv, ua npuas dej, carbon dioxide, hmoov qhuav.
3.Yuav ua li cas rau nruab ib lub ruaj H2 roj av ntes?
Vim tias hydrogen sib zog dua huab cua, cov nplaim hluav taws xob hydrogen yuav nce sai thiab ua rau muaj kev puas tsuaj tsawg dua li hydrocarbon combustion. Yog li feem ntau lub H2 ntes tau teeb tsa 30-60cm deb ntawm lub qab nthab, nrog lub sensor tig downwards.one unit hydrogen detector npog 25M2 cheeb tsam. Ntsuas ntau yam 0-100%lel(0-4%vol). Nyob deb ntawm qhov chaw uas muaj hlau nplaum thiab hluav taws xob.
Lub combustible gas detection alarm system muaj xws li ib tug combustible gas detector, ib tug combustible gas alarm controller thiab hluav taws kub thiab lub teeb tswb. Nws tuaj yeem ceeb toom ua ntej thaum qhov concentration ntawm cov roj combustible leaked nyob rau hauv qhov chaw tiv thaiv yog qis dua qhov qis tawg txwv, yog li tiv thaiv cov roj combustible to. Hluav taws kub thiab tawg xwm txheej tshwm sim los ntawm
