AI Technical Summary
While increasing the thickness of the packing layer in existing circulating water cooling towers can improve cooling efficiency, the improvement in heat dissipation efficiency is limited, and scale and impurities are easily accumulated, increasing the difficulty of cleaning.
The system combines movable and fixed packing layers. The movable packing layer is driven by a cam to swing up and down, increasing the contact area between the airflow and the hot water and generating disturbance. Combined with the design of secondary and main vents, the cooling method is optimized.
Without increasing the difficulty of cleaning, it significantly improves the cooling efficiency of the cooling tower, enhances the contact effect between airflow and hot water, reduces scale accumulation, and increases heat dissipation.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of cooling tower, specifically relates to an open circulating water cooling tower. BACKGROUND
[0002] The working principle of the existing circulating water cooling tower is that hot water is sprayed from the top of the cooling tower, forming water droplets or water film, and at the same time, external air enters the tower through a fan or natural ventilation, and flows reversely or synchronously with the falling hot water. In this process, part of the water evaporates and absorbs heat, reducing the water temperature, and the cooled water is collected in a water collecting pool and then pumped back to the system for recycling.
[0003] Among them, the filler layer plays an important role, hot water is sprayed to the filler layer through the spray head, thereby delaying the falling speed of hot water droplets, prolonging the contact time and increasing the contact area of hot water and air, so as to achieve the purpose of improving the cooling effect. In order to further improve the cooling efficiency, the contact time of hot water and air can be prolonged by increasing the thickness of the filler layer. However, with the increase of the thickness of the filler layer, the heat dissipation efficiency is more and more weak, and the filler layer with excessive thickness is more prone to accumulate scale, impurities and microorganisms, which aggravates the risk of blockage and increases the cleaning difficulty.
