Description

Technical Field

[0001] The utility model belongs to the technical field of closed cooling towers, and in particular relates to an energy-saving closed cooling tower. Background Art

[0002] A closed cooling tower places a tubular heat exchanger inside the tower, and ensures the cooling effect through heat exchange between circulating air, spray water outside the tube and circulating water inside the tube. Since the circulating water is a closed cycle inside the tube, it can ensure that the water quality is not polluted, which well protects the efficient operation of the main equipment and increases its service life. When the outside temperature is low, the spray water system can be stopped to save water. With the implementation of the national energy-saving and emission reduction policy and the increasing scarcity of water resources, closed cooling towers have been widely used in steel metallurgy, power electronics, mechanical processing, air-conditioning systems and other industries in recent years.

[0003] In the existing closed cooling tower, a spray device is usually required to spray the pipes during use. After a long period of use, scale will form on the surface of the pipes. When the spray equipment sprays them, the scale will be flushed into its own water reservoir. At this time, when the spray device performs the spraying operation again, the scale will be pumped into its own delivery pipe, causing internal blockage and may also cause blockage of the nozzle, thereby causing damage to the spray device, affecting the cooling of the pipes and causing low work efficiency.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0016] 2. The utility model can block the scale washed down on the circulation pipe by slidingly installing the filter plate on the fixed plate and the water inlet, so that it cannot enter the water reservoir, thereby ensuring that there are no impurities in the water reservoir, and the internal pipes will not be blocked to affect the spraying effect. When the filter plate needs to be cleaned, it can be slid out by unplugging the pin to clean it, so that it can be flexibly fixed and disassembled, increasing its service life and ensuring its filtering effect.
