Sulfur dioxide yog cov pa phem uas tsim kev puas tsuaj rau tib neeg lub cev. Nws yog xim tsis muaj xim thiab muaj ntxhiab tsw ntxhiab. Thaum lub concentration ntawm sulfur dioxide nyob rau hauv cov huab cua tsuas yog 1ppm (ib feem ntawm ib lab), peb yuav hnov lub siab ntawm kev tsim txom thiab tsis xis nyob. Lub tshuab kuaj kab mob sulfur dioxide yog ib qho cuab yeej rau kev kuaj xyuas qhov concentration ntawm cov pa thiab tuaj yeem saib xyuas cov sulfur dioxide zoo.
1. Txoj Cai Ua Haujlwm
Sulfur dioxide Gas Detectoryog ua raws li ntau yam kev ntsuas roj, feem ntau suav nrog plaub pawg hauv qab no: txoj kev nqus ultraviolet, electrochemical method, fluorescence method thiab infrared spectroscopy method.
Kev siv dav tshaj plaws yog cov txheej txheem electrochemical, uas siv cov tshuaj tiv thaiv redox ntawm sulfur dioxide ntawm cov electrode los tsim cov teeb liab tam sim no los txiav txim siab nws cov concentration. Cov txheej txheem ua tiav ntawm kev ua haujlwm kom paub qhov kev tshawb pom ntawm sulfur dioxide gas, concentration zaub, thiab tswb tom qab qhov concentration tshaj tus qauv.
2. Qhov zoo
Siab rhiab heev thiab raug: Electrochemical sensors siv cov tshuaj tiv thaiv redox ntawm sulfur dioxide ntawm cov electrode los tsim tam sim no, thiab qhov loj tam sim no yog proportional rau sulfur dioxide concentration. Txoj kev no muaj qhov rhiab heev thiab raug thiab tsim nyog rau kev tshawb pom ntawm qis -concentration sulfur dioxide.
Cov lus teb ceev ceev: Tom qab lub sensor hu rau sulfur dioxide, feem ntau nws tuaj yeem ua tiav cov txiaj ntsig ruaj khov nyob rau hauv 30 vib nas this, uas yog tsim rau tiag tiag - lub sijhawm saib xyuas thiab xwm txheej xwm txheej ceev.
Muaj zog portability: Lub sensor yog me me, tsawg zog noj (feem ntau<1W), easy to integrate into handheld or portable devices, and suitable for rapid on-site detection.
Tus nqi thiab kev saib xyuas zoo: Electrochemical sensors muaj cov nqi tsim khoom tsawg thiab tsis tas yuav tsum muaj kev kho ua ntej rau kev ua haujlwm, uas yog qhov tsim nyog rau kev xa tawm loj thiab kev siv sijhawm ntev -.
Kev xaiv siab: Los ntawm kev ua kom zoo dua cov khoom siv hluav taws xob thiab cov qauv electrolyte, qhov cuam tshuam ntawm kev cuam tshuam cov pa roj xws li H₂S thiab mercaptans tuaj yeem txo qis, thiab qhov kev tshawb pom tshwj xeeb tuaj yeem txhim kho.
High precision: Qhov kev ua yuam kev tom qab calibration tuaj yeem tswj tau li ntawm ± 2%, ua tau raws li qhov tseeb ntawm kev lag luam kev nyab xeeb thiab kev saib xyuas ib puag ncig.
Cov txheej txheem electrochemical sib txuas cov yam ntxwv ntawm cov lus teb ceev ceev, siab rhiab heev thiab tus nqi qis, thiab yog qhov kev xaiv tseem ceeb rau SO₂ tshawb pom hauv kev lag luam kev nyab xeeb, kev saib xyuas ib puag ncig thiab cov khoom siv nqa tau.
3. Daim ntawv thov teb
Sulfur dioxide detector tuaj yeem siv rau hauv ntau qhov chaw hauv kev tsim khoom. Nws lub hom phiaj ua kom muaj kev nyab xeeb.
Kev lag luam teb: Saib xyuas SO₂ to los yog emission concentration generated nyob rau hauv cov txheej txheem ntawm cov tshuaj nroj tsuag, thermal fais fab nroj tsuag, smelters, thiab lwm yam.
Kev tiv thaiv ib puag ncig: hauv nroog cov chaw saib xyuas huab cua zoo, kev soj ntsuam ib puag ncig ib puag ncig cov chaw ua si, thiab tiag - lub sijhawm taug qab ntawm huab cua muaj kuab paug tawm.
Laboratories thiab scientific kev tshawb fawb: roj kev ruaj ntseg xyuas nyob rau hauv tshuaj lom neeg kuaj, kev tshawb fawb ntawm cov pa phem tsim mechanisms, thiab lwm yam scenarios.
Kev lag luam mining thiab metallurgical: hlau smelting, sulfur mining, thiab lwm yam xwm txheej los tiv thaiv cov sulfur dioxide siab los ntawm kev ua phem rau cov neeg ua haujlwm.
Pej xeem kev nyab xeeb xwm txheej: qhov chaw ceev ceev thiab qhov kev pheej hmoo ntawm cov khoom muaj kuab paug nyob rau hauv cov pa hluav taws xob tam sim ntawd (xws li teeb meem tshuaj lom neeg).
Electrochemical tshawb pom ntawm SO₂ npog cov xwm txheej xws li kev nyab xeeb kev lag luam, kev saib xyuas ib puag ncig, kev teb thaum muaj xwm txheej ceev, kev nyab xeeb zaub mov, thiab kev noj qab haus huv ua haujlwm. Nws qhov kev txav tau yooj yim thiab tiag tiag - lub sijhawm xwm txheej ua rau nws yog ib qho tseem ceeb thev naus laus zis rau kev tshawb nrhiav roj hauv ntau qhov chaw.
