[0003] The central air-conditioning water system uses tap water as the working medium. When the external conditions (such as temperature, flow rate, concentration) change, the water quality is mostly in an unstable state, and phenomena such as scaling, corrosion, and biological slime will occur. If appropriate water treatment is not carried out, it will inevitably cause a series of problems such as pipeline blockage, corrosion leakage, and reduced heat exchange efficiency, affecting the normal operation of the entire central air-conditioning system. In order to prevent the formation of scale, inhibit the growth and reproduction of microorganisms, control the corrosion of equipment and pipelines, and extend the service life of equipment, a central air-conditioning circulating water treatment system is required to sterilize and remove scale to ensure the normal and safe operation of the system. After long-term use of the existing central air-conditioning circulating water sterilization and scale removal device, the filter plate is prone to blockage, and it is inconvenient to clean.
