Hydrogen sulfide (H2S) yog cov pa roj uas muaj kuab lom heev uas tuaj yeem ua rau lom lom thiab ua rau muaj kev hem thawj rau lub neej. Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb rau kev saib xyuas online ntawm hydrogen sulfide concentration. Tam sim no, ob peb txoj hauv kev tseem ceeb tau siv dav hauv kev saib xyuas online ntawm hydrogen sulfide, nrog rau txoj kev siv hluav taws xob, txoj kev kho qhov muag thiab txoj kev siv roj.
Muaj H2S Gas DetectorCov saib xyuas yog cov cuab yeej tseem ceeb los ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm hauv ib puag ncig uas muaj kev pheej hmoo ntawm H₂S. Nws muab cov lus ceeb toom ntxov rau kev khiav tawm ntawm cov neeg ua haujlwm thiab kev siv cov kev tswj xyuas los ntawm kev txheeb xyuas cov concentration hauv lub sijhawm tiag tiag thiab suab lub tswb thaum nws tshaj tus qauv. Lub tshuab ntsuas hydrogen sulfide tuaj yeem txuas ntxiv lossis xav tau ntsuas qhov concentration ntawm H₂S roj hauv huab cua. Lub tshuab kuaj xyuas hydrogen sulfide tuaj yeem sau cov ntaub ntawv xws li kev hloov pauv thiab lub tswb nrov hauv lub sijhawm, uas yog siv rau kev tshuaj xyuas tom ntej thiab kev tshuaj xyuas kev nyab xeeb. Tus nqi tam sim no pom qhov concentration yog feem ntau pom hauv ppm. Thaum kuaj pom H₂S qhov siab tshaj qhov kev nyab xeeb ntawm qhov pib, lub suab nrov thiab pom (thiab qee zaum kev co) lub tswb yuav tshwm sim los ceeb toom cov neeg ua haujlwm kom ua tiav tam sim ntawd (xws li khiav tawm thiab hnav lub tshuab ua pa).
Ua ntej ntawm tag nrho cov, electrochemical txoj kev yog ib tug ntau thiab txhim khu kev qha mus kom ze. Lub hauv paus ntsiab lus tseem ceeb yog siv lub ntsuas hluav taws xob los ntsuas qhov concentration ntawm hydrogen sulfide los ntawm kev hloov pauv tam sim no. Lub sensor muaj ib tug reactive caij. Thaum hydrogen sulfide los rau hauv kev sib cuag nrog cov khoom no, nws ua rau muaj kev hloov nyob rau hauv tam sim no, yog li indirectly ntsuas qhov concentration ntawm hydrogen sulfide. Ib qho ntawm qhov zoo ntawm txoj kev no yog nws lub siab rhiab heev thiab kev saib xyuas dav, uas tuaj yeem tshawb xyuas qhov kev hloov pauv ntawm hydrogen sulfide sai thiab raug. Tsis tas li ntawd, cov txheej txheem electrochemical kuj tseem tuaj yeem ua ke nrog lwm cov thev naus laus zis, xws li cov ntsuas kub thiab cov av noo, txhawm rau txhim kho qhov tseeb ntawm kev ntsuas ntsuas.
Qhov thib ob, txoj kev kho qhov muag kuj yog ib txoj hauv kev siv hauv internet saib xyuas rau hydrogen sulfide. Txoj kev no ntsuas qhov concentration ntawm hydrogen sulfide raws li kev hloov xim uas tsim los ntawm cov tshuaj tiv thaiv ntawm hydrogen sulfide thiab cov tshuaj tshwj xeeb. Optical sensors tuaj yeem paub qhov kev hloov xim no thiab hloov nws mus rau hauv lub teeb liab hluav taws xob, uas yog tom qab ntawd ua tiav kom tau txais qhov concentration ntawm hydrogen sulfide. Txoj kev no muaj qhov tseeb siab thiab lub sijhawm teb ceev, thiab yog qhov tsim nyog rau kev saib xyuas hydrogen sulfide concentrations nyob rau hauv ntau yam. Txawm li cas los xij, cov khoom siv tus nqi ntawm txoj kev kho qhov muag yog qhov siab, thiab cov kev cai rau ib puag ncig kuj tseem nruj heev.
Tsis tas li ntawd, cov txheej txheem roj kuj tseem siv tau rau kev saib xyuas online ntawm hydrogen sulfide. Txoj kev no ntsuas qhov concentration ntawm hydrogen sulfide los ntawm kev tsim cov cim ntsuas los ntawm cov tshuaj tiv thaiv ntawm hydrogen sulfide nrog cov tshuaj reagents. Qhov zoo ntawm cov tshuaj siv roj yog nyob rau hauv nws cov kev ruaj ntseg zoo, ceev cov tshuaj tiv thaiv ceev, thiab muaj peev xwm hloov mus rau kev saib xyuas ntawm qhov sib txawv ntawm cov concentration ntau los ntawm kev kho qhov feem ntawm cov tshuaj reagents. Txawm li cas los xij, kev siv cov qauv no yog txwv los ntawm ib puag ncig ib puag ncig, tshwj xeeb tshaj yog vim qhov kub thiab av noo muaj qhov cuam tshuam loj rau cov txiaj ntsig kev xeem.
