Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte recovery, in particular to an electrolyte defoaming filtering and recovery device. Background Art

[0002] Electrolyte is a chemical solution used in the electrolysis process. In industrial production, electrolyte can be used for various electrolytic reactions, such as electroplating, purification and other processes. When the electrolyte reacts in the electrolytic cell, a large number of bubbles will be generated. The bubbles will reduce the efficiency of the electrolytic reaction. At the same time, if the bubbles exist for a long time, they will damage the electrolytic equipment. Therefore, a defoaming filter device is required to treat the electrolyte after the reaction. However, the current defoaming filter device has the following defects:

[0003] The integrated defoaming and filtering device is not conducive to separation and maintenance. It is difficult to clean the stored liquid or replace the filler, which is not conducive to use. When defoaming, a small amount of electrolyte will be discharged through the exhaust port together with the vaporized impurities after heating, resulting in a waste of raw materials. When a batch of electrolyte has reacted, the electrolytic cell needs to be cleaned. The previous cleaning method is to disassemble the electrolytic cell and clean it component by component. Although this method cleans thoroughly, it is time-consuming and labor-intensive and can only be performed during shutdown and maintenance. The second method is to directly connect the cleaning liquid to the feed port of the electrolytic cell for flushing, and then collect the waste water for treatment. This method requires a huge amount of water, and when the electrolyte in the electrolytic cell needs to be recovered in the later stage, the processing and recovery cost increases due to the large amount of waste water. The current defoaming and filtering device does not have the function of cleaning the electrolytic cell, which is not practical enough.

[0004] To this end, we propose an electrolyte defoaming filtration and recovery device to solve the above problems. Utility Model Content
