The main disadvantages of the current tungsten metallurgy process are high acid and alkali consumption. hungarians have developed sodium tungstate ion membrane electrolysis process combined with solvent extraction. It can effectively reduce consumption of acid and alkali. Sodium tungstate ionic membrane electrolysis technology has good application prospect, but if for industrial application, low energy consumption of ionic membrane electrolyzer must be designed for industrial production. Through long-term research and practice, ionic membrane electrolytic tanks in chlor-alkali industry have made great development and important significance of designing sodium tungstate ionic membrane electrolyzer.

 

1. The plate electrode from distal cell:

Because the electrolyte is similar to water electrolyzer, they are all alkaline fluid. So process plastic plate electrode cell to simulate the water electrolyzer. It has carried on the exploration of sodium tungstate ion membrane electrolysis experiment. Test confirmed the possibility of using ionic membrane electrowinning extraction material liquid. Due to the slot on both ends of the plate electrodes embedded in tub, it’s unable to further shorten the pole pitch. So the relative unit energy consumption is higher, so it is necessary to improve tank structure. Although a vent in the tub, due to the smaller air chamber of the upper trough, gas is still not easy to discharge. Power consumption is higher.

2. The mesh electrode near polar distance electrolyzer:

First of all, the electric mixer can thin stagnation layer thickness and reduce energy consumption. And it can make the uniform flow distribution and effectively prevent the local acid. Secondly, using the pump electrolytic cell is feasible. It is possible to use plastic instead of metal, which is beneficial to save material. Finally, chlor-alkali electrolyzer was basically can be applied to sodium tungstate ion membrane electrolysis. The effect is better than any other electrolyzers.
