Description

Technical Field

[0001] The utility model belongs to the technical field of electrolysis, and in particular relates to a multifunctional flow electrolytic cell device. Background Art

[0002] In view of climate change and the resulting need for energy and raw material transformation, electrochemical processes such as water electrolysis will become increasingly important in the future. The essence of electrolysis is filtration technology. Filtration technology is a technology that separates solid particles, impurities in liquids or gases, microorganisms or other substances from fluids by physical, chemical or biological methods. Product flow cells are used in the separation of electrolytes. In the context of energy and raw material transformation, electrochemical processes have advantages because they use electricity instead of chemical reagents and are used in green synthesis processes such as electrosynthesis;

[0003] An electrolytic cell is a device that uses electrical energy to break down chemical substances into simpler components. Its working principle is based on the electrolysis reaction of an electrolyte solution under the action of an applied voltage. Usually, an electrolytic cell contains two electrodes, one called the anode and the other called the cathode, which are immersed in an electrolyte solution.

[0004] The current existing technology uses reagents to complete redox reactions. Reagents will cause certain pollution to the environment, especially when treating wastewater or waste liquid, and a large amount of reagents are required in certain cases, which also increases the cost. The use of reagents is risky in the event of improper operation or equipment failure, and may pose safety risks such as fire, explosion or chemical leakage. In addition, the gas after electrolysis in the traditional electrolytic solution process contains moisture, which is not convenient to use and store. Utility Model Content
