An electrolysis device for preparing ultra-high-purity deuterium gas from heavy water

Abstract

The invention discloses an electrolysis device for preparing ultra-high-purity deuterium gas by using heavy water as a raw material, comprising an electrolysis box, two electrode rods are fixedly connected to the bottom of the electrolysis box, and a control block is fixedly connected to the top of the top of the electrolysis box , the inside of the control block is filled with evaporative liquid, and the end of the slide bar away from the electrolytic box is fixedly connected with a mounting plate, the side wall of the electrolytic box is rotatably connected with a screw rod, and the side wall of the electrolytic box is provided with a movable fixed box, so The side wall of the fixed box is fixedly connected with two connecting blocks, the connecting block at the lower end is slidably sleeved on the side wall of the slide bar, and the side wall of the connecting block at the lower end is elastically connected to the side wall of the electrolytic box by the first spring. connect. The invention can avoid the situation that the electrolytic solution is consumed during the electrolysis process, which leads to the reduction of the conductive efficiency of the solution, and can keep the solution in the electrolytic box with good conductive performance at all times, thereby ensuring the electrolytic efficiency of heavy water.

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
