Description
Technical Field
[0001] The utility model relates to the technical field of potassium-type ion membrane electrolysis equipment, in particular to an electrolytic cell with a liquid level regulating function. Background Art
[0002] A primary application of potassium-type ion-exchange membrane electrolysis equipment is the electrolysis of potassium hydroxide solution (KOH) to produce high-purity potassium hydroxide. During the electrolysis process, an electric current passes through the electrolytic cell, reducing potassium ions at the cathode to form potassium metal or potassium hydroxide, while simultaneously producing hydrogen. Oxygen or other byproducts are produced at the anode. The ion-exchange membrane separates the anode and cathode, preventing cross-contamination between products and improving electrolysis efficiency.
[0003] The ion membrane technology used in potassium-type ion membrane electrolysis equipment can significantly improve the efficiency of the electrolysis process. The main function of the ion membrane is to selectively allow potassium ions to pass through while blocking other ions and gases, reducing the occurrence of side reactions, thereby improving the purity and yield of the electrolysis products. The electrolyzer is the core component of potassium-type ion membrane electrolysis equipment.
[0004] In the process of realizing the present invention, the inventors discovered that the prior art has the following problems: 1. When an existing ordinary electrolytic cell is in use, as the solution in the cathode chamber and the anode chamber of the electrolytic cell is consumed, a water level difference will appear in the cathode chamber and the anode chamber of the electrolytic cell. When the water level difference on both sides of the ion membrane is large, a pressure difference will be generated, which will affect the service life of the ion membrane; 2. When the existing ordinary electrolytic cell is used for a long time and needs to be cleaned, it is generally necessary to manually clean it from the top of the electrolytic cell, which is time-consuming and labor-intensive.
