[0002] The water-saving closed cooling tower is a major improvement and upgrade of the traditional evaporative cooling technology and air cooling technology, and has obvious comprehensive benefits of energy saving and water saving. It combines the advantages of both evaporative cooling and air cooling, and is widely used in high water-consuming industries such as chemical, petrochemical, and electric power, as well as water-scarce areas. The working principle of the closed cooling tower is based on the principle of heat exchange, which reduces the temperature of water through heat exchange between water and air to achieve a cooling effect. When in use, in order to save water resources, water treatment agents are usually added to treat cooling water with poor water quality for repeated use. However, due to the closed cooling tower, it is not easy to add water treatment agents quantitatively. At the same time, after adding, due to the large area of ​​the cooling tower water storage tank, it is not easy to quickly process, and there are certain shortcomings. For this reason, we propose a water-saving closed cooling tower. Utility Model Content
