I-Industrial Online Residual Chlorine Sensor

Isimiso Sokusebenza

I-Electrolyte ne-osmotic membrane ihlukanisa amasampula engqamuzana e-electrolytic kanye namanzi, ulwelwesi olukwazi ukungena lungakwazi ukukhetha ukungena kwe-ClO-;phakathi kwakho kokubili

i-electrode inomehluko ongaguquki ongaba khona, amandla amanje akhiqizwayo angaguqulwa abei-chlorine eseleukugxilisa ingqondo.

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

Ku-anode: Cl^-+ Ag → AgCl + e^-

Ngoba ezimweni ezithile zokushisa nezimo ze-pH, i-HOCl, i-ClO- ne-chlorine esele phakathi kobudlelwane obuguquguqukayo, ngale ndlela ingakalai-chlorine esele.

Izinkomba Zobuchwepheshe

Isondlo Sansuku Zonke

(1) Njengokutholakala kwesistimu yonke yokulinganisa isikhathi eside sokuphendula, ukuphuka kwe-membrane, akukho chlorine kwabezindaba, nokunye, kuyadingeka ukufaka esikhundleni se-membrane, ukugcinwa kokushintshwa kwe-electrolyte.Ngemuva kwe-membrane ngayinye yokushintshanisa noma i-electrolyte, i-electrode idinga ukuphinda iphindwe futhi ilinganiswe.

(2) Izinga lokugeleza kwesampula lamanzi anethonya ligcinwa lingashintshi;

(3) Ikhebula kufanele ligcinwe endaweni ehlanzekile, eyomile noma engenisa amanzi.

(4) Inani lokuboniswa kwensimbi kanye nenani langempela liyahluka kakhulu noma inani lensalela ye-chlorine liyiziro, ingase yomise i-electrode ye-chlorine ku-electrolyte, isidingo sokujova kabusha ku-electrolyte.Izinyathelo ezithile zimi kanje:

Khipha ikhanda lefilimu yekhanda le-electrode (Qaphela: ukuze ungalimazi ifilimu ephefumulayo), ukhiphe ifilimu kuqala ngaphambi kwe-electrolyte, bese i-electrolyte entsha ithululelwa ifilimu kuqala.Okujwayelekile njalo ezinyangeni ezi-3 ukwengeza i-electrolyte, isigamu sonyaka ngekhanda lefilimu.Ngemuva kokushintsha i-electrolyte noma ikhanda le-membrane, i-electrode iyadingeka ukuthi ilinganiswe kabusha.

(5) I-Electrode polarization: i-cap ye-electrode isusiwe, futhi i-electrode ixhunywe entweni, futhi i-electrode ingaphezu kwamahora angu-6 ngemva kokuba i-electrode i-polarized.

(6) Uma ingasebenzisi indawo isikhathi eside ngaphandle kwamanzi noma imitha isikhathi eside, kufanele isuse i-electrode ngokushesha, vala isivalo sokuvikela.

(7) Uma i-electrode ihluleka ukushintsha i-electrode.

Kusho Ukuthini I-Residual Chlorine?

I-chlorine eyinsalela yizinga eliphansi le-chlorine elisele emanzini ngemva kwesikhathi esithile noma isikhathi sokuthintana ngemva kokufakwa kwayo kokuqala.Kuyisivikelo esibalulekile engcupheni yokungcoliswa kwamagciwane alandelayo ngemva kokwelashwa—inzuzo eyingqayizivele nebalulekile empilweni yomphakathi.I-Chlorine iyikhemikhali eshibhile futhi etholakala kalula okuthi, lapho incibilika emanzini acwebile ngenani elanele, izobhubhisa izinto eziningi ezibangela izifo ngaphandle kokuba yingozi kubantu.I-chlorine, noma kunjalo, isetshenziswa njengoba izinto eziphilayo zibhujiswa.Uma kune-chlorine eyanele, izosala emanzini ngemva kokuba zonke izinto eziphilayo sezicekeleke phansi, lokhu kubizwa ngokuthi i-chlorine yamahhala.(Umfanekiso 1) I-chlorine yamahhala izohlala emanzini ize ilahlekele ngaphandle noma isiqede ukungcola okusha.Ngakho-ke, uma sihlola amanzi futhi sithola ukuthi isekhona i-chlorine yamahhala esele, kufakazela ukuthi izilokazane eziningi eziyingozi emanzini zisusiwe futhi kuphephile ukuthi ziphuzwe.Lokhu sikubiza ngokulinganisa insalela ye-chlorine.Ukulinganisa insalela ye-chlorine emanzini kuyindlela elula kodwa ebalulekile yokuhlola ukuthi amanzi ahanjiswayo aphephile yini ukuphuzwa.
