Hauv qhov ntsuas pom roj, electrochemical txoj cai ntsuas yog siv feem ntau. Feem ntau, kev kuaj pom kev ua kom muaj pa roj yog nyob ntawm electrochemical txoj cai ntsuas. Cov roj cua muaj xws li: hydrogen sulfide, carbon monoxide, ammonia, sulfur dioxide thiab lwm yam gases lom.Yog li ntawd, peb yuav tsum nkag siab meej txog cov qauv hluav taws xob ntawm lub ntsuas, xyuam xim rau cov teeb meem hauv kev siv, kom peb siv tau kom raug kom tsis txhob muaj ib qho twg tsis tsim nyog poob.
Ua ntej tshaj plaws, cia peb kawm cov qauv loj ntawm lub ntsuas cua. Lub tshuab hluav taws xob (electrochemical sensor) feem ntau muaj diffusion kem, lub nplhaib sib khi, siv hluav taws xob, hluav taws xob induction electrode, khub electrode, thiab electrolyte.Nws yog yooj yim nrhiav tau tias muaj lub luag haujlwm tseem ceeb: lub tshuab hluav taws xob. Txij li nws ua kua, nws yuav qhuav, yog li nws muaj qee lub sijhawm ntawm kev ua neej. Kuj tseem muaj ib lub sijhawm teev cov khoom tshwj xeeb, yog li nws tsis tuaj yeem npaj sijhawm ntev dhau. Yog li peb thaum xaiv lub ntsuas roj, tshwj xeeb ntsuas hluav taws xob ntsuas hluav taws xob, peb yuav tsum them sai sai rau hnub tim ntawm kev tsim khoom, tsis txhob siv lub sijhawm ua haujlwm luv.
Los ntawm txoj kev, vim li cas qee tus neeg yuav cov lus rov hais tias lawv tsis txhob siv lub tshuab kuaj pom tom qab yuav lawv tsuas yog muab tso rau hauv Tshuag xwb, tab sis tsis muaj qhov rov nrhiav pom thaum lawv siv tom qab lub sijhawm ntev.Tias vim tias cov electrolyte ua tsis tau tejyam thiab ua kom qhuav.
Electrochemical gas sensor, tshwj xeeb yog kom tsis txhob muaj cov av noo loj, qhov kub thiab qhov siab thiab qhov ntsuas qis thiab qhov chaw qis qis rau ib puag ncig, uas yuav txo tau qhov electrolyte.Yog li ntawd, peb yuav tsum them sai sai rau qhov hloov ntawm ib puag ncig kev ua haujlwm zoo hauv kev siv.Ob li ntawd, qhov xwm txheej phem yuav sai sai xaus cov sensor lub neej.Qhov ntxiv, cov siab ntawm cov roj kuj tseem tuaj yeem ua rau kev puas tsuaj ntawm lub tshuab hluav taws xob.Piv txwv li, peb lub tshuab kuaj xaiv qhov ntsuas ntau ntawm 500ppm. Peb lub ntsuas roj feem ntau nyob ib puag ncig 400ppm, lossis lub siab qhov siab dhau ntawm qhov ntsuas ntau yuav ua rau kev noj nrawm ntawm lub tshuab hluav taws xob hauv lub sensor, uas yuav luv luv rau kev siv sijhawm.Under ntev lub sij hawm siab siab qhov ntsuas yuav cuam tshuam rau 2 xyoos Cov. Yog tias lub ntsuas roj muaj kev nruam nruam ntau dhau 60% ntawm qhov ntau, nws yuav ua rau lub ntsuas pa tsis dhau qhov ceev, tej zaum tsuas yog lub sijhawm pabcuam 1-2 lub hlis.Yog li ntawd, peb yuav tsum them sai sai rau tias seb cov pa roj thiab cov ntsiab lus zoo tsim nyog, tshwj xeeb tshaj yog cov ntsuas pa uas xav kom ntev lub sij hawm raug rau lub hauv paus hluav taws xob ntawm lub ntsuas hluav taws xob.Peb saib xyuas kev xaiv ntawm cov pa hluav taws xob uas yuav tsim kev puas tsuaj rau lub sijhawm luv luv rau kev kuaj pom.
