Description

technical field [0001] The invention belongs to the technical field of electrolytic cells, and in particular relates to a multistage electrolytic cell. Background technique [0002] The electrolyzer is mainly used to prepare qualified uranium-containing solution and provide reducing agent to other systems. The traditional electrolyzer has poor corrosion resistance, and only has a temperature measuring device without a temperature control device, which has great limitations in use and high requirements on the surrounding environment. Each level of the drain port at the bottom of the tank needs to be set up with a separate valve to control the drain port. There are many hazardous waste leakage points, and the bottom is not suitable for maintenance and investigation. Due to the large number of electrode plates in the electrolytic cell and the short distance, the distance between the traditional electrode plates has a large deviation, and the depth of the tank is generally larg...

AI Technical Summary

Problems solved by technology

The traditional electrolyzer has poor corrosion resistance, and only has a temperature measuring device without a temperature control device, which has great limitations in use and high requirements on the surrounding environment.

Each level of the drain port at the bottom of the tank needs to be set up with a separate valve to control the drain port. There are many hazardous waste leakage points, and the bottom is not suitable for maintenance and investigation.

Due to the large number of electrode plates in the electrolytic cell and the short distance, the distance deviation between the traditional electrode plates is large, and the depth of the tank is generally large. It is easy to cause a short circuit of the electrode plates during installation and use, and there are many electrode connection covers, and the positioning accuracy is poor.

Moreover, due to the special working conditions of the electrolytic cell, the service time is long, and the slight shaking of the electrode is also easy to contact the wall plate, electrode and partition of the electrolytic cell, resulting in a short circuit, and the pipelines are not connected by insulation, which is poor in safety.
