Dab tsi yog lub twj tso kua mis hom sulfur dioxide ntes
Peb coob tus nkag siab txog qhov tseem ceeb ntawm kev tshawb nrhiav roj. Nrog rau kev txhim kho hauv zej zog thiab kev nce qib ntawm cov cuab yeej technology, cov khoom siv roj av tshiab tau tshwm sim tas li los pab peb daws cov teeb meem ntawm kev tshawb nrhiav roj. Niaj hnub no, cia peb qhia rau koj seb lub tshuab kuaj kab mob sulfur dioxide yog dab tsi, thiab cia peb saib ua ke.
Cov roj sulfur dioxide (cov tshuaj formula SO2) yog cov tshuaj sulfur oxide ntau tshaj plaws thiab yooj yim tshaj plaws. Sulfur dioxide kuj yog cov roj uas tsis muaj xim nrog cov ntxhiab tsw ntxhiab thiab yog ib qho ntawm cov pa phem hauv huab cua.
Dab tsi yog vim li cas rau kev tsim cov sulfur dioxide
Feem ntau ntawm cov sulfur dioxide emissions yog tshwm sim los ntawm smelting ntawm sulfur-muaj ores, combustion ntawm fossil fuels, industrial khib nyiab gas los ntawm zus tau tej cov sulfuric acid, phosphate chiv, thiab lub tsheb tsav tsheb. Cov tiam nyob rau hauv cov cheeb tsam nyob deb nroog yog vim cov emissions ntawm thee pellets, thee ncuav mog qab zib, honeycomb thee, thiab lwm yam roj los ntawm cov neeg ua liaj ua teb. Cov kev tshawb fawb ntsig txog tau pom tias 90 feem pua ntawm cov sulfur dioxide emissions tam sim no los ntawm cov pa hluav taws xob hluav taws xob.
Puas yog sulfur dioxide tsim kev puas tsuaj rau tib neeg kev noj qab haus huv:
Sulfur dioxide yog ib qho precursor ntawm sulfuric acid uas tuaj yeem hnov mob nrog lwm yam khoom hauv huab cua los ua sulfites thiab sulfate hais, uas yog nqus los ntawm tib neeg lub cev thiab khaws cia hauv lub ntsws, ua rau ua pa tsis ua haujlwm. Yog tias sib xyaw nrog dej thiab sib cuag nrog daim tawv nqaij, frostbite yuav tshwm sim. Volcanic eruptions tso ib tug loj npaum li cas ntawm sulfur dioxide thiab dej nag los tsim sulfuric acid los nag, uas yuav ua mob rau daim tawv nqaij thiab ob lub qhov muag.
Online sulfur dioxide detector, tsim nyog rau kev tshawb nrhiav online txuas ntxiv thiab tshuaj xyuas ntawm sulfur dioxide concentration hauv ntau qhov chaw muaj thiab tshwj xeeb; Kev xaiv ntawm qhov chaw tswb muaj nuj nqi (kho tau siab thiab qis tswb), tawg-pov thawj thaiv txoj kev tsim nyog rau ntau qhov chaw txaus ntshai. Cov cuab yeej siv tau nrog ntau lub tswb tswj, PLC, DCS thiab lwm yam kev tswj hwm, thiab tuaj yeem ua tiav cov haujlwm xws li kev saib xyuas cov chaw taws teeb, lub tswb nrov, thiab cov ntaub ntawv hauv computer.
