Problems solved by technology

The traditional electrolytic cell only has a temperature measuring device, and the temperature cannot be effectively controlled during electrolysis. The use is limited and the requirements for the surrounding environment are high.
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 and reduces the electrolysis.

Abstract

The invention discloses a multi-stage electrolysis method. The method comprises the following steps: 1. assembly of an electrode plate mechanism; 2. installation of a deflector; 3. connection of the electrode plate mechanism and a tank body; Five, electrolysis of hexavalent uranium solution to form tetravalent uranium solution. The method of the invention has simple steps, reasonable design and low cost, and the electrolysis process is convenient to operate. The hexavalent uranium solution is formed into a tetravalent uranium solution through multi-stage electrolysis. Plate short circuit, high safety and reliability.

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 in the electrolysis, so the use is limited and the requirements for the surrounding environment are high. 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 large. Dur...
