Description

Technical Field

[0001] The invention relates to cooling equipment for industrial circulating water, in particular to a cooling tower. Background Art

[0002] The cooling or condensation of process media in the industrial field generally requires circulating water with a lower temperature. After absorbing heat, the circulating water needs to go to the cooling tower to evaporate and dissipate heat for cooling, and then be sent to the heat exchanger again to absorb the heat of the process medium. Cooling towers are divided into two categories: open heat exchange and closed heat exchange. The so-called open heat exchange is to directly contact the circulating water with the air from the environment for heat transfer. Since the water and air are in direct contact, it is also called wet air cooling; while in closed heat exchange, under the suction of the fan, the air in the environment is sucked into the tower for convective heat exchange with the circulating water in the coil. The circulating water in this closed heat exchange is isolated from the ambient air, and the two are not in direct contact, so it is called dry air cooling.

[0003] The existing cooling towers have the following defects: first, the packing of the cooling tower usually needs to be replaced every three years. The existing packing is replaced by manually removing the old packing in the tower and then inserting new packing in the tower body. This maintenance and replacement method is not only labor-intensive but also time-consuming. The long-term replacement operation will affect the normal operation of the production equipment; second, the existing cooling tower forms a water circulation refrigeration method between the cooling tower and the refrigerated device, and the cooling water in the tower adopts a one-way non-circulating refrigeration method, so the heat exchange effect is not good, the heat exchange efficiency is not high, and some cooling towers even waste water resources.
