Abstract

The invention discloses an electrolysis device for preparing ultra-pure deuterium gas by taking heavy water as a raw material, which comprises an electrolysis box, two electrode bars are fixedly connected to the bottom in the electrolysis box, a control block is fixedly connected to the top in a fixed box on the electrolysis box, the control block is filled with evaporated liquor, and a mounting plate is fixedly connected to one end, far away from the electrolysis box, of a sliding rod. a lead screw is rotatably connected to the side wall of the electrolysis box, a movable fixing box is arranged on the side wall of the electrolysis box, two connecting blocks are fixedly connected to the side wall of the fixed box, the connecting block located at the lower end is arranged on the side wall of the sliding rod in a sliding and sleeving mode, and the side wall of the connecting block located at the lower end is elastically connected with the side wall of the electrolysis box through a first spring. According to the electrolysis device, the situation that the conductive efficiency of a solution is reduced due to the fact that the electrolyte is consumed in the electrolytic process can be avoided, the solution in the electrolytic tank can be kept to have good conductive performance all the time, and therefore the electrolytic efficiency of heavy water is guaranteed.

Description

technical field [0001] The invention relates to the technical field of an electrolysis device for preparing deuterium gas, in particular to an electrolysis device for preparing ultra-high-purity deuterium gas by using heavy water as a raw material. Background technique [0002] Deuterium gas is a colorless, odorless, non-toxic combustible gas. Traditional deuterium gas preparation is generally by electrolysis of heavy water. [0003] The electrolytic heavy water device in the prior art generally has the following deficiencies during use: [0004] 1. In order to improve the electrolysis efficiency of heavy water, the staff will generally add alkaline electrolyte to the electrolytic cell during the electrolysis process to enhance the conductivity of the liquid in the electrolytic cell. However, during the electrolysis process, the alkaline electrolyte will absorb air carbon dioxide and generate carbonate, so that the conductive medium is continuously consumed, thereby reducin...

Problems solved by technology

[0004] 1. In order to improve the electrolysis efficiency of heavy water, the staff will generally add alkaline electrolyte to the electrolytic cell during the electrolysis process to enhance the conductivity of the liquid in the electrolytic cell. However, during the electrolysis process, the alkaline electrolyte will absorb air carbon dioxide and generate carbonate, so that the conductive medium is continuously consumed, thereby reducing the electrolysis efficiency of heavy water and reducing the working efficiency of the electrolysis device;

[0005] 2. During the electrolysis process, the carbonate produced by the reaction between the electrolyte and carbon dioxide will adhere to the surface of the anode rod and the cathode rod, hindering the full contact between the liquid in the electrolytic cell and the electrode rod, and also reducing the electrolysis efficiency of heavy water
