[0002] Coal chemical industry is an important part of chemical production. The dust content in the air at the site of coking plants in coal chemical industry is relatively more than that in other places. The dust entering the circulating water system at the cooling tower of the circulating water system in coking plants is more than that in other places, which causes the indexes such as turbidity, hardness and suspended solids of the circulating water to exceed the standard. As a result, there are many impurities in the circulating water, blocking the heat exchanger, and it is necessary to regularly clean the circulating water tank. At present, the air for cooling the circulating water directly enters the cooling tower pool. The dust in the air will gradually deposit at the bottom of the pool after entering the circulating water, and it needs to be manually cleaned after the cooling tower is shut down. Manually cleaning the cooling tower not only increases the labor intensity of workers, but also reduces the labor productivity. Therefore, it is very necessary to provide a circulating water cooling tower that can filter dust to reduce the labor intensity of workers. Summary of the Utility Model
