[0002] Ion exchange technology is a method of using ion exchange resins to replace and release ions in a solution, thereby separating and purifying the solution. Ion exchange technology is widely used in the fields of electricity, chemical industry, biology, medicine, food, etc. This technology can be used to remove harmful substances such as hardness ions, heavy metal ions, radionuclides, etc. in water; it can also be used to prepare high-purity chemicals, biological products and drugs; it can also be used for acid-base adjustment, pigment removal, desalination, etc. in food processing. A water cap is a part with a specific structure and material, which is mainly used to support the resin layer and uniformly arrange the medium during water treatment. Its main features include high mechanical strength, large specific gap area, and good mechanical stability. The material of the water cap is usually stainless steel, and the styles include tower-shaped water caps, laminated water caps, and wire-wound water caps. The working principle of the water cap not only involves an efficient filtration mechanism, but also includes how to ensure the uniform arrangement and appropriate flow of the medium through backwashing and other technical means in specific application scenarios.

[0003] Ion exchange resin is usually a polymer material with a certain void structure and surface chemical functional groups. Commonly used ion exchange resins are divided into two types: styrene and acrylic. Ion exchange resins are generally spherical, with a diameter between 0.3-1.2mm and colors such as black, white, brown, etc. They have high mechanical strength, can withstand a certain pressure, and can be used at a specific medium flow rate. Ion exchange resins are usually loaded in ion exchangers for use. A porous plate is set at the bottom or middle of the ion exchanger, and a water cap is installed on the hole of the porous plate. Ion exchange resin is loaded above the water cap. The number of water caps in an ion exchanger ranges from more than ten to hundreds. Once a water cap leaks, it will cause resin leakage, causing equipment shutdown. In severe cases, resin leakage into the production system will cause system damage. Summary of the invention
