Problems solved by technology

However, in conventional electrochemical reactors, the two-dimensional electrode reactor electrode has a small specific surface area and low mass transfer efficiency, resulting in poor treatment effect and serious corrosion of the plates; filling granular or debris-like materials between the plates of the traditional two-dimensional electrolyzer, Constitute a three-dimensional electrode reactor, which improves the specific surface area, current efficiency, and mass transfer efficiency of the reactor, and the treatment effect is significantly better than that of a two-dimensional electrode reactor.
In recent years, some people have done some research on three-dimensional electrode materials and reactor structures, but the catalytic materials supported by granular electrodes are easy to precipitate, and the practical applicability of the reactor is not strong. There is no reasonable rectification power supply system, resulting in high energy consumption.
