Gas Sensor Daim ntawv thov nyob rau hauv dej zoo saib xyuas thiab tu

Abstract Industrial thiab pej xeem nthuav dav nyob rau hauv ob peb lub xyoo dhau los tau ua ib qho tseem ceeb pab rau kev degradation dej. Qee cov pa roj emanating los ntawm cov chaw kho dej yog tshuaj lom thiab tawg, uas yuav tsum tau txheeb xyuas, xws li hydrogen sulphide, carbon dioxide, methane, thiab carbon monoxide. Kev saib xyuas dej zoo yuav tsum tau tsim kom tau raws li kev cai lij choj, ib puag ncig, thiab kev sib raug zoo. Kev saib xyuas cov dej tsis zoo yog qhov nyuaj vim qhov sib txawv, qhov xwm txheej, thiab qhov tsis txaus ntseeg ntawm cov kab mob uas yuav tsum tau kuaj xyuas. Cov roj emanating los ntawm cov txheej txheem kho no ua lub luag haujlwm tseem ceeb hauv kev kho dej, saib xyuas, thiab tswj. Gas sensors tuaj yeem siv los ua cov cuab yeej kev nyab xeeb hauv cov txheej txheem dej huv. Cov pa roj sensors tau txais cov teeb liab tawm tswv yim hauv tshuaj lom neeg, lub cev, thiab lom neeg lub cev thiab hloov mus rau hauv cov teeb liab hluav taws xob. Cov roj sensors tuaj yeem ntsia tau rau hauv cov txheej txheem dej khib nyiab sib txawv. Hauv qhov kev tshuaj xyuas no, peb nthuav tawm cov kev nce qib hauv lub xeev, kev txhim kho thaj chaw, thiab kev ua tiav thev naus laus zis uas tau coj mus rau kev tsim cov roj sensors rau kev ntsuas dej zoo. Lub luag haujlwm ntawm cov roj sensors hauv kev saib xyuas thiab kev saib xyuas dej zoo yog tham txog, thiab cov kev ntsuas sib txawv thiab lawv cov cuab yeej tshawb nrhiav thiab cov ntaub ntawv ntsuas tau piav qhia txog lawv qhov zoo thiab qhov tsis zoo tau raug sau tseg. Thaum kawg, cov ntsiab lus thiab kev pom zoo rau yav tom ntej cov lus qhia ntawm cov pa sensors hauv kev saib xyuas thiab kev saib xyuas dej zoo yog muab

Cov lus tseem ceeb Gas sensor / Dej zoo / Kev kho dej / Cov dej khib nyiab / Tshuaj oxygen xav tau / Cov pa oxygen xav tau

Taw qhia
Ib qho teeb meem tseem ceeb tshaj plaws ntawm ib puag ncig uas cuam tshuam rau tib neeg yog kev loj hlob thoob ntiaj teb cov pa phem ntawm cov khoom siv dej nrog ntau txhiab lub ntuj thiab kev lag luam. Nws tau tshwm sim ntau dua nyob rau hauv kaum xyoo tsis ntev los no vim yog globaliza-tion, industrialization, thiab sai sai ntawm cov pejxeem. Nyob ib ncig ntawm 3.4 billion tus neeg tsis muaj kev nkag mus rau cov dej huv huv, uas muaj feem cuam tshuam nrog ntau dua 35% ntawm tag nrho cov neeg tuag hauv cov tebchaws tsim [1]. Cov dej khib nyiab yog siv rau cov dej uas muaj tib neeg pov tseg, tsev neeg, tsiaj pov tseg, rog, xab npum, thiab tshuaj lom neeg. Lub sij hawm sensor yog muab los ntawm "sentio", lo lus Latin rau kev xaav lossis kev soj ntsuam. Lub sensor yog ib qho cuab yeej siv los kuaj xyuas qhov kev xav tau ntawm kev txaus siab thiab teb rau qhov muaj cov kab mob sib kis lossis cov tshuaj ntsuam xyuas nyob hauv ib puag ncig. Ntau xyoo dhau los, tib neeg muaj cov txheej txheem tshawb nrhiav dej zoo tshaj plaws los txheeb xyuas cov kab mob, cov organic, thiab cov tshuaj inorganic-cals thiab lwm yam tsis zoo (piv txwv li, pH, hardness (solved Ca thiab Mg) thiab turbidity (cloudiness) ). los yog ffline nrog kev pab los ntawm cov sensors niaj hnub no, kev saib xyuas hauv online ntawm cov dej yog qhov zoo dua vim cov lus teb ceev ntawm cov tshuab no muaj qhov tsis muaj qhov tsim nyog sensors uas tuaj yeem siv rau kev saib xyuas kom zoo thiab kev saib xyuas dej zoo ib yam ntawm cov txheej txheem siv dej ntau tshaj plaws yog kev sib txuas ntawm cov khoom siv hluav taws xob. accumulating organisms feem ntau ntawm cov reactors yog ua los ntawm ffline cov kauj ruam, uas txhais tau hais tias cov ntaub ntawv sampling yog tsawg zaus thiab cov kev tshwm sim yog ib qho teeb meem rau kev tswj kom zoo ntawm lub tshuab thiab ua
