Hydrogen sulfide yog ib qho hluav taws kub, tsis muaj xim tsis muaj roj uas muaj qhov txawv txav - qe tsw. Nws tsis tshua muaj siv ncaj qha hauv kev tsim khoom; es, raug rau hydrogen sulfide feem ntau tshwm sim raws li ib tug byproduct ntawm tej yam tshuaj tiv thaiv, lub ntuj decomposition ntawm proteins, los yog raws li ib tug impurity nyob rau hauv lwm yam tshuaj. Kev lag luam uas muaj kev pheej hmoo siab ntawm hydrogen sulfide raug suav nrog kev kho dej khib nyiab, kev tsim ntawv, roj av refining, chiv tsim, tsim fiber ntau, thiab tsim cov khoom siv tshuaj lom neeg.

1.Primary Applications ntawm Hydrogen Sulfide
Hydrogen sulfide yog dav siv nyob rau hauv kev tsim cov txheej txheem xws li coke ntau lawm, roj av refining, hlau smelting, natural gas purification, thee gas production, tawv tanning, pharmaceuticals, paper manufacturing, thiab synthesis ntawm chemical fibers. Nws ua hauj lwm ob lub luag hauj lwm: ua raws li cov pa phem uas ua phem rau ib puag ncig, thaum tseem sawv cev rau cov khoom muaj txiaj ntsig sulfur uas tuaj yeem hloov pauv thiab sib xyaw ua ntau yam khoom siv tshuaj. Tam sim no, thoob tebchaws hydrogen sulfide emissions tshaj 10 lab tons hauv ib xyoos; yog li ntawd, kev saib xyuas zoo ntawm cov emissions no yog qhov tseem ceeb tshaj plaws rau kev tiv thaiv ib puag ncig thiab kev ua haujlwm tag nrho.
2.Dab tsi yog Cov Kev Siv Feem Ntau ntawm H2S Detectors?
H2S detectors feem ntau yog siv rau qhov tiag -lub sij hawm saib xyuas ntawm hydrogen sulfide concentrations nyob rau hauv ib puag ncig. Lawv muab kev ceeb toom-feem ntau ntawm lub tswb nrov, pom cov cim, lossis kev vibration- txhawm rau tiv thaiv cov xwm txheej cuam tshuam nrog lom, hluav taws kub, lossis tawg. Raws li lawv txoj kev xa tawm, cov cuab yeej no tau muab faib ua ob hom: portable thiab tsau units.
Tsim los rau kev tiv thaiv tus kheej, xws li kev kuaj xyuas kev nyab xeeb ua ntej nkag mus rau qhov chaw kaw.
Txhawb kev soj ntsuam ntawm lub xov tooj ntawm tes thiab saib xyuas kev ua haujlwm ib ntus (piv txwv li, thaum lub sijhawm ua piv txwv, kev tso dej, tshuaj xyuas lub tank, thiab lwm yam).
Feem ntau feature triple-mode tswb (saudible, pom, thiab vibration), cov ntaub ntawv logging peev xwm, thiab qhia rau ncov concentrations los yog sij hawm-Weighted Averages (TWA).
Feem ntau muaj qhov ntsuas IP65 / IP67 ingress tiv thaiv, nrog qee cov qauv muaj peev xwm tiv taus qhov kev sim poob (piv txwv li, los ntawm qhov siab ntawm 7.6 meters).
Tsim los rau 24-teev kev saib xyuas online tas li, chav tsev no tau teeb tsa hauv thaj chaw uas muaj kev pheej hmoo siab ntawm cov pa xau (xws li cov chaw nres tsheb, cov chaw ua liaj ua teb, thiab cov dej phwj tuaj).
Nws tso tawm 4-20 mA lossis RS-485 cov cim, tso cai rau kev koom ua ke nrog DCS, PLC, lossis lub hauv paus saib xyuas.
Nws txhawb kev ntsuas kev ceeb toom thaum muaj xwm txheej ceev xws li lub tswb nrov hauv thaj chaw deb thiab kev sib txuas ua haujlwm ntawm lub tshuab ua pa lossis kaw -off li qub.
5.Tej daim ntawv thov scenarios suav nrog:
Petrochemical nroj tsuag; natural gas extraction thiab kis chaw
Cov chaw kho dej phwj tuaj; kev siv hluav taws xob hauv av; chaw nres tsheb pov tseg
Coal mining, metallurgy, pulp thiab ntawv, tshuaj, thiab lwm yam kev lag luam
Kev ua haujlwm nyob rau hauv qhov chaw kaw (piv txwv li, tso tsheb hlau luam, tunnels, nkoj tuav).
