Multistage electrolysis method

Abstract

The invention discloses a multistage electrolysis method. The method comprises the following steps: 1, assembling an electrode plate mechanism; 2, installing a guide plate; 3, connecting the electrodeplate mechanism with a cell body; 4, injecting an electrolyte; and 5, electrolyzing the hexavalent uranium solution to form a tetravalent uranium solution. The method is simple in step, reasonable indesign and low in cost, the electrolysis process is convenient to operate, the hexavalent uranium solution forms the tetravalent uranium solution through multi-stage electrolysis, multiple electrodeplates are isolated and completely isolated from the wall plate of the electrolytic cell, short circuit of the electrode plates is avoided, and safety and reliability are high.

Description

technical field [0001] The invention belongs to the technical field of electrolysis, and in particular relates to a multistage electrolysis method. Background technique [0002] The electrolyzer is mainly used to prepare qualified uranium-containing solution and provide reducing agent to other systems. The traditional electrolyzer only has a temperature measuring device, and the temperature cannot be effectively controlled during electrolysis, so its use is limited and it has 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 traditional electrode plates have a large distance deviation and the tank body is generally deep. During installation and us...

AI Technical Summary

Problems solved by technology

The traditional electrolyzer only has a temperature measuring device, and the temperature cannot be effectively controlled during the electrolysis, so its use is limited and it has high requirements on the surrounding environment.

Each level of the drain port at the bottom of the tank needs to be equipped 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 and reduces the electrolysis.
