Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water-saving and mist-eliminating dry and wet cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate excess heat generated in industry or refrigeration and air conditioning to lower the water temperature by using water as a circulating coolant and dissipating it into the atmosphere to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.

[0003] The existing cooling towers have a high water consumption, which leads to an increase in the cost of use. In order to save costs and reduce waste, some cooling towers use structures such as water collectors to collect moisture entrained in the air, reduce water loss, and thus reduce costs. For example, Chinese Patent Publication No. CN211695958U discloses "a water-saving and mist-eliminating dry-wet cooling tower", which forms a two-stage dry cooling system by setting a pressurized air-liquid plate air cooler and an active water collector, which can greatly improve the dry cooling load ratio of the dry-wet cooling tower, so that the air humidity at the cooling tower outlet is greatly reduced. Compared with the traditional dry-wet cooling tower, the water-saving performance and mist-eliminating performance are greatly improved. A water collecting pool is set at the bottom of the cooling tower, and the water in the water collecting pool is transported to the first cooling water flow channel. The outlet of the first cooling water flow channel is connected to the secondary spray water pipe, which is used to spray the heat-exchanged water onto the cooling tower filler;

[0004] However, in actual use, since the air inhaled by the cooling tower inevitably contains dust and debris, some impurities will adhere to the filler when passing through the filler, and some impurities will combine with the spraying water mist during spraying, and will wash away the impurities on the filler when flowing through the filler, resulting in a large number of impurities in the water collection tank, which will easily clog the nozzle when spraying the water in the water collection tank. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art that the inhaled air contains dust and debris, resulting in a large number of impurities in the water collection tank, and the nozzle is easily blocked when the water in the water collection tank is sprayed, and a water-saving and mist-eliminating dry-wet cooling tower is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
