Description

Technical Field

[0001] The invention relates to the technical field of electrochemical synthesis, and in particular to an electrolytic cell with a flow field regulating component. Background Art

[0002] With the development of electrochemical technology, it is widely used not only in the industrial synthesis of inorganic compounds such as chlor-alkali industry, strong oxidants, and highly active metal oxides, but also in the preparation of organic compounds. In electrochemical synthesis, electrodes as electron acceptors or donors avoid the use of some harmful and dangerous chemical redox reagents, reduce the generation of chemical waste to a certain extent, and improve production safety. Electrochemical synthesis requires an electrolytic cell, which is different from the equipment used for traditional chemical reactions. There are two types of electrolytic cells: one is a diaphragm-free electrolytic cell, in which the anode and cathode are placed in the same container; the other is a diaphragm electrolytic cell, in which the anode and cathode are separated by a diaphragm to prevent the reactions of the cathode and cathode from affecting each other.

[0003] At present, the existing electrolytic cell flow field control form is single, and the internal flow field can only be analyzed through the import and export data. The bubbles generated during the electrolysis process are very important for the flow field distribution and circulation effect of the reaction liquid inside. In order to solve the adverse effects of bubbles on the flow field and enhance the mass transfer performance of the electrolytic reaction, timely discharge of bubbles or change of flow field distribution according to bubble size and flow rate are effective measures.
