Kev Lag Luam Online Residual Chlorine Sensor

Txoj Cai Ua Haujlwm

Electrolyte thiab osmotic membrane cais cov electrolytic cell thiab cov qauv dej, permeable membranes tuaj yeem xaiv rau ClO- nkag mus; ntawm ob qho tib si

electrode muaj qhov sib txawv ntawm qhov muaj peev xwm ruaj khov, qhov muaj zog tam sim no tuaj yeem hloov pauv mus rau hauvcov tshuaj chlorine seemkev tsom mus rau ib yam dab tsi.

Ntawm lub cathode: ClO^-+ 2H+ + 2e^-→ Cl^-+ H₂O

Ntawm qhov anode: Cl^-+ Ag → AgCl + e^-

Vim tias nyob rau hauv qee qhov kub thiab pH tej yam kev mob, HOCl, ClO- thiab cov chlorine seem ntawm kev hloov pauv ruaj khov, ua li no tuaj yeem ntsuas qhovcov tshuaj chlorine seem.

Cov Ntawv Qhia Txog Kev Siv Tshuab

Kev Txij Nkawm Txhua Hnub

(1) Xws li kev tshawb pom ntawm tag nrho cov txheej txheem ntsuas lub sijhawm teb ntev, daim nyias nyias tawg, tsis muaj chlorine hauv cov xov xwm, thiab lwm yam, nws yog qhov tsim nyog los hloov daim nyias nyias, kev saib xyuas ntawm cov electrolyte hloov. Tom qab txhua daim nyias nyias lossis electrolyte pauv, lub electrode yuav tsum tau repolarized thiab calibrated.

(2) Tus nqi ntws ntawm cov dej ntws raug khaws cia tas li;

(3) Lub cable yuav tsum khaws cia rau hauv qhov chaw huv, qhuav lossis dej nkag.

(4) Tus nqi ntawm cov cuab yeej tso saib thiab tus nqi tiag tiag sib txawv heev lossis tus nqi seem ntawm cov tshuaj chlorine yog xoom, tej zaum yuav ua rau cov electrolyte qhuav hauv cov electrolyte, qhov yuav tsum tau txhaj tshuaj dua rau hauv cov electrolyte. Cov kauj ruam tshwj xeeb yog raws li nram no:

Tshem lub hau zaj duab xis ntawm lub electrode (Ceeb toom: tsis txhob ua kom puas tsuaj rau zaj duab xis ua pa), lim cov zaj duab xis ua ntej cov electrolyte, tom qab ntawd cov electrolyte tshiab nchuav rau hauv zaj duab xis ua ntej. Feem ntau txhua 3 lub hlis kom ntxiv cov electrolyte, ib nrab xyoo rau lub taub hau zaj duab xis. Tom qab hloov cov electrolyte lossis lub taub hau membrane, cov electrode yuav tsum tau rov kho dua.

(5) Electrode polarization: lub hau electrode raug tshem tawm, thiab lub electrode txuas nrog lub cuab yeej, thiab lub electrode yog ntau tshaj 6 teev tom qab lub electrode yog polarized.

(6) Thaum tsis siv lub sijhawm ntev yam tsis muaj dej lossis lub 'meter' ntev, yuav tsum tshem lub electrode tam sim ntawd, thiab muab lub hau tiv thaiv tso rau.

(7) Yog tias lub electrode tsis ua haujlwm ces hloov lub electrode.

Txhais tau tias Residual Chlorine yog dab tsi?

Cov tshuaj chlorine seem yog cov tshuaj chlorine tsawg uas tseem tshuav nyob hauv dej tom qab ib lub sijhawm lossis lub sijhawm sib cuag tom qab nws thawj zaug siv. Nws yog ib qho kev tiv thaiv tseem ceeb tiv thaiv kev pheej hmoo ntawm kev kis kab mob tom qab kev kho mob - ib qho txiaj ntsig tshwj xeeb thiab tseem ceeb rau kev noj qab haus huv pej xeem. Chlorine yog ib qho tshuaj pheej yig thiab yooj yim nrhiav tau uas, thaum yaj rau hauv dej ntshiab hauv qhov ntau txaus, yuav rhuav tshem feem ntau cov kab mob ua rau muaj kab mob yam tsis muaj kev phom sij rau tib neeg. Txawm li cas los xij, cov tshuaj chlorine raug siv tag nrho thaum cov kab mob raug rhuav tshem. Yog tias ntxiv cov tshuaj chlorine txaus, yuav muaj qee qhov seem hauv dej tom qab tag nrho cov kab mob raug rhuav tshem, qhov no hu ua cov tshuaj chlorine dawb. (Daim Duab 1) Cov tshuaj chlorine dawb yuav nyob hauv dej kom txog thaum nws ploj mus rau lub ntiaj teb sab nraud lossis siv tag nrho rhuav tshem cov kab mob tshiab. Yog li ntawd, yog tias peb sim dej thiab pom tias tseem muaj qee cov tshuaj chlorine dawb tshuav, nws ua pov thawj tias feem ntau cov kab mob txaus ntshai hauv dej tau raug tshem tawm thiab nws muaj kev nyab xeeb rau haus. Peb hu qhov no ntsuas cov tshuaj chlorine seem. Kev ntsuas cov tshuaj chlorine seem hauv cov dej yog ib txoj hauv kev yooj yim tab sis tseem ceeb los xyuas kom meej tias cov dej uas tau xa tuaj muaj kev nyab xeeb rau haus.
