Udindo, Zochitika, ndi Ntchito za Polarographic Dissolved Oxygen Sensors

Mfundo Yogwirira Ntchito

Masensa a okosijeni osungunuka a polarographic amagwira ntchito motengera mfundo za electrochemical, makamaka pogwiritsa ntchito ma elekitirodi a Clark. Sensa imakhala ndi cathode ya golide, anode ya siliva, ndi electrolyte yeniyeni, zonse zotsekedwa ndi nembanemba yosankha.

Poyeza, mpweya umafalikira kudzera mu nembanemba kupita ku sensa. Pa cathode (golide electrode), mpweya umachepa, pamene anode (silver electrode), okosijeni kumachitika. Izi zimapanga kufalikira kwapano molingana ndi kuchuluka kwa okosijeni wosungunuka m'chitsanzo, ndikupangitsa kuyeza kolondola.

Zofunika Kwambiri

Polarographic kusungunuka mpweya masensa amatengedwa ambiri chifukwa cha makhalidwe awo apadera:

1. Kulondola Kwambiri ndi Kukhudzidwa:
   • Imatha kuzindikira mpweya wosungunuka wosungunuka, wokhala ndi miyeso yotalikirapo kuyambira 0.01μg/L mpaka 20.00mg/L ndi zosintha mpaka 0.01μg/L. Izi ndizofunikira kwambiri pamagwiritsidwe ntchito ngati madzi a boiler ndi semiconductor ultrapure water monitoring.
2. Nthawi Yoyankha Mwachangu:
   • Amayankha pasanathe masekondi 60 (zogulitsa zina zimakwaniritsa nthawi yoyankha mkati mwa masekondi 15), kuwonetsa mwachangu kusintha kwa mpweya wosungunuka.
3. Zofunika Pakukonza Zochepa:
   • Mapangidwe amakono nthawi zambiri safuna kusinthidwa pafupipafupi kwa electrolyte, kuchepetsa ndalama zolipirira nthawi yayitali komanso kuyesetsa. Komabe, nthawi ndi nthawi kuwongolera ndi kusintha kwa membrane ndikofunikira.
4. Kukhazikika Kwamphamvu ndi Kuthana ndi Kusokoneza:
   • Nembanemba yosankhidwa bwino imalekanitsa bwino zonyansa ndi zonyansa, ndikuwonetsetsa kuti miyeso yokhazikika komanso yodalirika.
5. Kulipiritsa Kutentha Kwawokha:
   • Masensa ambiri amaphatikizapo chojambulira cha kutentha chomwe chimapangidwira kuti chiteteze kutentha kwadzidzidzi, kukonza zolakwika zoyezera zomwe zimachitika chifukwa cha kusinthasintha kwa kutentha.
6. Mapangidwe Anzeru ndi Ophatikizidwa:
   • Masensa ambiri ali ndi njira zoyankhulirana (mwachitsanzo, RS485) ndi ma protocol othandizira (monga Modbus), zomwe zimathandizira kuphatikizika kwamakina owongolera makina ndi nsanja za IoT zowunikira zakutali.

Zochitika za Ntchito

Masensa a okosijeni osungunuka a polarographic amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana:

1. Njira Zamakampani ndi Kusamalira Madzi:
   • Boiler Feedwater Monitoring: Ndikofunikira kwambiri m'mafakitale monga kupanga magetsi, mankhwala, ndi zitsulo, pomwe mpweya wosungunuka kwambiri ungayambitse dzimbiri la mapaipi ndi zida zachitsulo.
   • Kusamalira Madzi Owonongeka ndi Kuwunika Kutaya: Miyezo ya okosijeni yosungunuka imakhudza mwachindunji zochitika za tizilombo tating'onoting'ono m'matauni ndi mafakitale.
   • Semiconductor ndi Ultrapure Water Production: Zofunikira zamadzi zoyera kwambiri pakupanga zamagetsi zimafunikira kuwunika bwino momwe mpweya wasungunuka.
2. Kuyang'anira Zachilengedwe ndi Kafukufuku wa Sayansi:
   • Kuwunika kwa Ubwino wa Madzi, Mitsinje, ndi Nyanja: Mpweya wosungunuka ndi chizindikiro chachikulu chamadzi odziyeretsa okha komanso thanzi lachilengedwe.
   • Aquaculture: Kuwunika kwenikweni kwa mpweya wosungunuka kumathandiza kupewa hypoxia m'zamoyo za m'madzi, kupititsa patsogolo ulimi.
3. Biotechnology and Pharmaceutical Industries:
   • Kusungunuka kwa okosijeni wosungunuka kuyenera kuyendetsedwa ndendende mu bioreactors (mwachitsanzo, nayonso mphamvu ndi chikhalidwe cha maselo) kuti zitsimikizire kukula kwabwino kwa tizilombo kapena ma cell.
4. Makampani a Chakudya ndi Chakumwa:
   • Miyezo ya okosijeni yosungunuka imatha kukhudza kukoma kwa chinthu, mtundu, ndi moyo wa alumali, zomwe zimapangitsa kuwunika kukhala kofunika panthawi yopanga.

Mayiko/Magawo Omwe Amagwiritsidwa Ntchito Nthawi zambiri

Kukhazikitsidwa kwa masensa a okosijeni osungunuka a polarographic kumagwirizana kwambiri ndi kukula kwa mafakitale, malamulo a chilengedwe, komanso kupita patsogolo kwaukadaulo:

1. Kumpoto kwa Amerika:
   • United States ndi Canada zimakhazikitsa malamulo okhwima oteteza chilengedwe ndi miyezo yaubwino wamadzi, zomwe zimapangitsa kuti masensa awa azigwiritsidwa ntchito kwambiri m'mafakitale apamwamba monga mphamvu, mankhwala, ndi mankhwala.
2. Europe:
   • Maiko monga Germany, UK, ndi France, omwe ali ndi malamulo okhwima a chilengedwe (mwachitsanzo, EU Water Framework Directive) ndi matekinoloje apamwamba oyeretsa madzi akuwonongeka, ndi omwe amagwiritsa ntchito kwambiri masensa awa.
3. Asia-Pacific:
   • China: Kufuna kukukula mwachangu chifukwa cha kuyesetsa kwachitetezo cha chilengedwe (mwachitsanzo, mfundo ya "Water Ten Plan") ndi chitukuko chamankhwala amadzi ndi ulimi wam'madzi.
   • Japan ndi South Korea: Mafakitale apamwamba kwambiri amagetsi, semiconductor, ndi makina olondola amadzi amayendetsa zosowa zosiyanasiyana za zida zowunikira bwino kwambiri zamadzi.
4. Madera ena olemera omwe ali ndi malamulo okhwima a chilengedwe amagwiritsanso ntchito kwambiri masensa awa.

Mapeto

Masensa a polarographic osungunuka okosijeni, ndi kulondola kwawo, kuyankha mwachangu, komanso kukhazikika, ndi zida zofunika kwambiri pakuwunika ndi kusanthula kwamadzi. Amagwira ntchito yofunika kwambiri pakuwonetsetsa chitetezo cha mafakitale, kuchita bwino, komanso kuteteza chilengedwe.

Titha kuperekanso njira zosiyanasiyana zothetsera

1. M'manja mita kwa Mipikisano parameter madzi khalidwe

2. Dongosolo la Buoy loyandama lamtundu wamadzi wamitundu yambiri

3. Burashi yotsuka yokha yamadzi ambiri amadzimadzi

4. Seti yathunthu ya ma seva ndi pulogalamu yopanda zingwe, imathandizira RS485 GPRS / 4g/WIFI/LORA/LORAWAN
