Description
Technical field
The utility model relates to a kind of alkaline device, particularly relates to a kind of conductive unit of the oxygen cathode electrolyzer for the alkaline industry.
Background technology
Chlorine industry produces by product hydrogen simultaneously by water generates caustic soda and the chlorine of electrolyzing table salt, and is the basic chemical industry primary industry that occupies critical role in national economy.Present domestic alkaline has diaphragm process and ionic membrane method, and power consumption cost accounts for 60% in the production cost, therefore reduces power consumption and has very important significance for improving chlor-alkali industry economic benefit tool.
Specifically, chlor-alkali plant is produced 1 ton of caustic soda, produces simultaneously the hydrogen of 0.886 ton of chlorine and more than 1200 cubic metre, approximately needs power consumption 2500 degree, is the electricity-eating tiger in the chemical industry, and annual power consumption accounts for 20% of chemical industry electricity consumption integral body.People are devoted to reduce the energy consumption of chlorine industry always for many years, and institute's Adopts measure comprises the improvement barrier film, improve electric groove structure, transform graphite anode as metal anode etc.But fundamentally, the huge current consumption of chlorine industry is to be determined by its chemical reaction itself.Therefore, must fundamentally change the electrochemical reaction of electrolytic saltwater, thereby reduce theoretical decomposition voltage, reach energy-conservation purpose.As everyone knows, the main electro-chemical reaction equations of chlor-alkali production is at present:
Anode: 2Cl
--2e=Cl
2
Negative electrode: 2H
2O+2e=H
2+ 2OH
-
Wherein, Ф
Sun=1.359 volts of Ф
Cloudy=-0.828 volt
So, its theoretical decomposition voltage: E=Ф
Sun-Ф
Cloudy=1.359-(-0.828)=2.187 volt
If the total reaction of electrode process is changed into:
2NaCl+H
2O+1/
2O
2=2NaOH+Cl
2↑
2Cl
--2e=Cl
2
Anode:
Negative electrode: 2H
2O+1/
2O
2+ 2e=2OH
-
Wherein, Ф
Sun=1.359 volts of Ф
Cloudy=0.391 volt
So, its theoretical decomposition voltage: E=Ф
Sun-Ф
Cloudy=1.359-0.391=0.968 volt
Can find out from above two kinds of electrode processes, their anodic reaction process does not become, and negative electrode is decomposed into hydrogen by original water under electric energy effect and hydroxide radical is changed into water and airborne oxygen effect generates hydroxide radical, makes it no longer produce hydrogen.Relatively can find out according to theoretical decomposition voltage, theoretical decomposition voltage has reduced by 1.22 volts.Therefore, in the chlor-alkali device, use oxygen cathode electrolyzer tool to have very important significance.
