Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic zinc, in particular to a cooling device for ammonia-process electrolytic zinc electrolyte. Background Art

[0002] Ammonia electrolysis has strict requirements on temperature. Too high temperature will affect the electrolysis process and cause the quality of zinc flakes to decline. In addition, the electrolyte is mainly composed of ammonium chloride and zinc ammine complex. Too high temperature will deteriorate the environment. In acid electrolysis, an air cooling tower is used to cool the solution, so the temperature of the electrolytic cell can be effectively controlled and the impact on the surrounding environment is minimal. If the traditional air cooling device for acid electrolysis is used, chloride is easy to crystallize in the cooling tower, resulting in the inability to operate the cooling system normally.
