In addition, some soluble inorganic salts will be produced in the water, causing scale deposition in equipment and pipelines or corrosion of metal equipment pipelines. The circulating water needs to be desalinated. Since the electrosorption technology does not need to use acid and alkali solutions when treating circulating water, it will not cause secondary pollution to the environment, the required voltage is low, and it will not cause side reactions such as electrolysis reactions. The working principle is simple, the equipment is easy to operate and has a long service life. Therefore, the electrosorption technology is an ideal technology for treating circulating water. In the prior art, most of them use multiple electrode plates placed in a box, and then circulating water is passed into the box.

When cleaning the electrode plates, multiple electrode plates need to be disassembled and cleaned, and the inner wall of the box needs to be cleaned, which is time-consuming and labor-intensive, increasing the difficulty of desalination and cleaning.
