Sulfur dioxide yog cov pa roj lom uas muaj ntxhiab tsw ntxhiab tsw (zoo ib yam li cov khoom sib tw hlawv). Kev nqus pa tuaj yeem ua rau ua pa nyuaj, ua rau hnoos, ua pa nyuaj, hauv siab nruj, thiab mob caj pas. High concentration exposure tuaj yeem ua rau pulmonary edema, bronchitis, thiab ua rau muaj kev phom sij rau lub neej. Lub tswb nrov tuaj yeem ua lub tswb nrov (feem ntau yog lub suab nrov thiab pom lub tswb) ua ntej qhov kev xav tau nce mus txog qib txaus ntshai, ceeb toom rau ntawm - cov neeg ua haujlwm hauv chaw khiav tawm ntawm thaj chaw txaus ntshai kom tsis txhob muaj tshuaj lom. Txawm hais tias SO₂ nws tus kheej tsis yog ib qho yooj yim asphyxiant, nws tuaj yeem hloov pauv cov pa oxygen ntawm qhov chaw siab heev, thiab lub tswb kuj tuaj yeem qhia ncaj qha tias cov ntsiab lus oxygen hauv ib puag ncig yuav tsis txaus.
Sulfur dioxide Gas DetectorLub tswb nrov feem ntau yog txuas nrog lub hauv paus tswj chav, hluav taws xob tiv thaiv hluav taws xob, lub tshuab ua pa thaum muaj xwm ceev, thiab lwm yam. Thaum lub tswb nrov tshwm sim, cov txheej txheem xwm txheej ceev tuaj yeem pib pib, xws li: ua kom muaj kev sib tsoo hluav taws xob kom dilute cov pa roj; Kaw cov qhov cuam tshuam los yog txiav tawm cov khoom noj kom tsis txhob muaj qhov xau. Qhia rau cov neeg ua haujlwm ruaj ntseg lossis pab neeg teb thaum muaj xwm txheej ceev los daws qhov xwm txheej.
Lub hauv paus tseem ceeb hauv lub tswb yog SO₂ gas sensor (hom hom xws li electrochemical sensors, semiconductor sensors, infrared sensors, thiab lwm yam). Lub sensor tsis tu ncua kuaj pom qhov concentration ntawm SO₂ hauv huab cua ambient thiab hloov cov teeb liab concentration rau hauv hluav taws xob teeb liab. Lub microprocessor nyob rau hauv lub ntsuas piv cov hluav taws xob teeb liab nrog lub preset tswb pib (feem ntau yog luv luv -lub sij hawm raug tso cai concentration STEL thiab/los yog lub sij hawm- luj qhov nruab nrab tso cai concentration TWA). Thaum qhov pom tau tias muaj ntau tshaj qhov pib ntawm lub tswb, lub ntsuas yuav qhib tam sim ntawd lub tswb nrov hauv zos thiab qhov muag pom (siab -decibel buzzer thiab flashing light). High- cov khoom siv kawg kuj tseem yuav xa cov teeb liab mus rau chav tswj lossis chaw taws teeb saib xyuas.
Sulfur dioxide nws tus kheej tsis yog-flammable, tab sis nws feem ntau tshwm sim nyob rau hauv cov txheej txheem kev lag luam uas cuam tshuam nrog kev sib txuas ntawm sulfur, hydrogen sulfide lossis kev ua cov sulfur- muaj cov zaub mov. Cov txheej txheem lossis ib puag ncig no tuaj yeem nrog lwm yam khoom siv hluav taws xob lossis kub kub. Kev xau tuaj yeem qhia tau tias cov txheej txheem cuam tshuam tsis muaj kev tswj hwm, ua rau muaj kev pheej hmoo ntawm hluav taws kub lossis tawg. Tswb tuaj yeem ua rau muaj kev kaw thaum muaj xwm txheej ceev lossis kev cuam tshuam kev nyab xeeb. Kev xau loj tuaj yeem yuam kom tag nrho cov kab ntau lawm lossis chaw tsim khoom raug kaw rau kev saib xyuas, ua rau muaj kev puas tsuaj loj. Kev ceeb toom ntxov tuaj yeem tiv thaiv me me los ntawm kev hloov mus rau qhov xwm txheej loj.
Cov tshuaj sulfur dioxide pa tawm lub tswb ntsuas yog qhov tseem ceeb "sentinel" hauv kev lag luam kev nyab xeeb thiab kev tiv thaiv kev noj qab haus huv. Los ntawm lub sijhawm tiag tiag - saib xyuas thiab lub tswb raws sijhawm, nws txo qhov kev pheej hmoo rau lub neej, kev noj qab haus huv, ib puag ncig, khoom vaj khoom tsev thiab kev tsim khoom los ntawm SO₂ to.
