[0002] The heat exchange system is a heat energy recovery and utilization system, which generally includes a heat absorber (heat exchanger), a regenerator and a cooler. Its function is to achieve heat exchange between fluids of different temperatures. Since the operation of the heat exchange system usually requires the use of water, scale is inevitably generated in the heat exchange system. The scale generated in the heat exchange system will affect the efficiency of heat exchange, so it is necessary to clean the scale regularly. During the scale cleaning process, a large amount of descaling water will be generated. In order to save water resources, the scale in the descaling water is usually filtered, treated and purified again, and then recycled, so water treatment equipment is needed.

[0003] The scale prevention and descaling water treatment equipment for heating boilers disclosed in Chinese patent CN219231628U can double filter and collect the dirt in the descaling water through the annular carrier plate inside the treatment cylinder and the first filter plate and the second filter plate, so as to facilitate its cleaning. The treatment cylinder and the support cylinder can be connected through the first connecting pipe and the second connecting pipe. The PP cotton filter plate and the activated carbon filter plate provided inside the support cylinder can play a role of deep filtering the water again, so as to have a structure for descaling water treatment and achieve the effect of water saving. However, while solving the problem, the scale prevention and descaling water treatment equipment for heating boilers has the following defects:

[0004] The water passing efficiency of the activated carbon filter plate and the PP cotton filter plate will decrease after long-term use, so they need to be replaced or disassembled for cleaning regularly. The activated carbon filter plate and the PP cotton filter plate are both threadedly connected to the inside of the support tube. Therefore, when disassembling the activated carbon filter plate and the PP cotton filter plate, the second connecting pipe and the first connecting pipe need to be disassembled, and then the support tube can be disassembled before the activated carbon filter plate and the PP cotton filter plate can be disassembled. The operation is complicated, time-consuming and labor-intensive. Utility Model Content
