Daim ntawv thov ntawm Gas Detector hauv Metallurgy
Cov khoom siv hluav taws xob hluav taws xob, cov khoom siv hluav taws xob ruaj khov, thiab ntau lub tshuab ntsuas roj kuj tau siv dav hauv metallurgy (smelting), feem ntau tsom rau kev tsim cov hlau thiab txhuas. Tuam Tshoj yog tus tsim khoom loj tshaj plaws hauv lub ntiaj teb. Nyob rau hauv xyoo tas los no, cov tuam txhab tsim khoom hlau thiab hlau tau raug cuam tshuam los ntawm kev siv roj av kev nyab xeeb hauv cov txheej txheem tsim khoom, thiab lawv txoj kev paub txog kev nyab xeeb tau nce siab thiab siab dua. Yog li ntawd, nws tau dhau los ua qhov tseem ceeb dua los siv cov khoom siv hluav taws xob los soj ntsuam cov concentration ntawm ntau yam roj.
Muaj ntau cov pa phem uas yuav tsum tau ua thaum lub sij hawm tsim cov hlau, xws li carbon monoxide (CO), ammonia (NH3), sulfur compounds, cyanide compounds, thiab benzene thaum lub sij hawm tsim khoom. Tsis tas li ntawd, cov pa ntshiab huv, muaj cov pa oxygen, thiab lwm yam tsim nyog rau cov txheej txheem ntau lawm. Nyob rau tib lub sijhawm, nws yog qhov yuav tsum tau siv nitrogen lossis argon ua cov roj tiv thaiv thaum ua cov hlau.
Hauv kev lag luam hlau thiab steel smelting ntau lawm, carbon monoxide yog ib qho tshuaj lom thiab muaj teeb meem. Tam sim no, cov roj tseem ceeb siv los ntawm kev lag luam steel yog thee roj. Nyob rau tib lub sijhawm, cov pa roj kuj tseem tsim tawm thaum lub sijhawm ua haujlwm ntawm cov tshuab hluav taws xob tawg, cov hloov pauv thiab cov qhov cub coke. Yog li ntawd, kev kuaj xyuas cov pa roj carbon monoxide thiab cov pa roj carbon monoxide yog qhov tseem ceeb los tiv thaiv cov pa roj carbon monoxide lom los yog cov pa tawg.
Vim tias kev ua haujlwm yuav tsum muaj dej ntau thiab lub zog, cov chaw tsim khoom steel feem ntau yuav tsum tau nruab nrog kev kho dej thiab cov chaw tsim hluav taws xob, uas kuj tsim cov pa phem hydrogen. Hydrogen cross-reacts nrog CO electrochemical sensors, yog li CO sensors muaj peev xwm lim hydrogen yuav tsum yog cov khoom siv hauv steel mills.
Nyob rau tib lub sijhawm, cov pa phem heev xws li hydrogen sulfide thiab cyanide tseem yuav koom nrog cov txheej txheem hlau thiab hlau, ua rau muaj kev phom sij ntau dua.
Siv cov khoom siv hluav taws xob sib txuas, cov khoom siv hluav taws xob ruaj khov, thiab ntau lub tshuab hluav taws xob los saib xyuas cov kev hloov pauv ntawm cov pa roj carbon monoxide thiab cov roj hluav taws xob hluav taws xob hauv online ib ntus. Ntev npaum li lub ntsuas roj xau xa tawm lub tswb ceeb toom, cov roj saib xyuas cov khoom nruab rau hauv chav ua haujlwm tseem yuav xa tawm lub tswb ceeb toom raws li, ua rau cov neeg ua haujlwm cuam tshuam lossis cov neeg ua haujlwm nyob rau hauv qhov chaw ua haujlwm tiv thaiv kom tsis txhob muaj kev txhim kho ntxiv. thiab ua rau muaj kev nyab xeeb.
