Abstract

The invention discloses a perchlorate electrolyzer which comprises a plurality of electrolysis baths, wherein the electrolysis baths are divided into at least three groups, the electrolysis baths in each group are connected in series, each group of the electrolysis baths is further connected with a circulation barrel, the circulation barrels are in stepped distribution and connected through overflow pipes, and the overflow pipe of the circulation barrel at a lowest position is connected with an electrolyzed liquid storage tank. An electrolytic process of perchlorate is as follows: chlorate electrolyte solution is used for electrolyzing in an electrolysis bath so as to obtain electrolyzed liquid, and the electrolyzed liquid is used for producing perchlorate products; the electrolytic process comprises that the perchlorate electrolyzer is used for circulated electrolyzing to electrolyte solution, and the electrolyzing temperature is controlled to be 60 to 70 DEG C. The perchlorate electrolyzer and the electrolytic process, provided by the invention, has the advantages that the current efficiency is improved and the chlorate conversion rate is increased.

Description

technical field [0001] The invention relates to the technical field of perchlorate electrolysis, in particular to a perchlorate electrolysis device and an electrolysis process. Background technique [0002] The perchlorate electrolysis process is to electrolyze the chlorate electrolyte in the electrolytic cell to obtain the electrolytic solution, which is used to produce perchlorate products.
