Cooling towers are widely used in industries, air-conditioning systems, electric power and other fields. It can be used to cool various industrial equipment, such as engines, boilers, smelting furnaces, etc. In air-conditioning systems, cooling towers can provide a cold source to lower the indoor temperature. In the electric power field, cooling towers can be used to cool the cooling water of reactors and generators in nuclear power plants.

[0003] Energy station cooling towers are usually installed outdoors and will generate loud noise during operation, which can easily affect the life, work and rest of surrounding residents. At the same time, long-term exposure to noise pollution will also cause residents to suffer from insomnia, anxiety, irritability and other conditions. Utility Model Content

When the cooling tower is working, a group of nozzles will spray the hot water inside a group of water pipes downwards. The filler layer can perform preliminary filtration on the hot water to remove impurities in the water to prevent the impurities from affecting the recycling of water. When the hot water is cooled, it will fall on the sponge pad, which can reduce the noise generated when water droplets fall. Then the cold water continues to fall downward and is filtered for the second time by the filter below to remove fine particles in the water. The treated cold water gathers at the bottom of the cooling tower waiting for secondary use. The first silencer insert will absorb the noise generated when air enters the cooling tower.

The rock wool layer is made of rock wool material and has good sound insulation and fire prevention properties. The fiberglass layer is a composite of glass fiber and organic polymer material, and has the characteristics of sound insulation, heat insulation, moisture resistance and corrosion resistance, and can effectively protect the internal structure. The cooling tower shell cooperates with other components to effectively reduce the noise generated when the cooling tower is working, so that residents can live a normal life and ensure that the health of residents is not affected by the noise of the cooling tower.
