Description

Technical Field

[0001] The utility model relates to the field of cooling tower equipment, in particular to a circulating cooling tower. Background Art

[0002] Cooling towers are structures used to cool water. They are commonly found in power plants, chemical plants, cement plants, and other factories that require a large amount of water temperature control. The stable operation of cooling towers is the basis for the stable operation of the entire circulating water device. The circulating water with a higher temperature is evenly sprayed onto the filler through the spray pipe in the cooling tower. The wind blowing in and the water sprinkled from above form convection to discharge the heat source. Part of the water evaporates in the convection, taking away the corresponding latent heat of evaporation, thereby reducing the temperature of the water. In chemical phosphoric acid production enterprises, the vacuum pump circulating cooling tower in the semi-water and di-water process in the original design has a lot of sludge in the circulating return water brought by the production system, and the production system is often stopped for cleaning, and the cooling effect is poor, resulting in frequent excess of system exhaust gas, multiple fines for environmental spot checks, abnormal system operation, frequent maintenance and cleaning, high labor costs, high base material consumption, and high operating costs, which have a negative impact on the economic benefits of the enterprise. Utility Model Content

[0009] A compound packing layer is also provided inside the tower body, and the compound packing layer is located below the spray device.

[0010] The advantage of adopting the above technical solution is that the high-temperature circulating water first enters the temporary storage tank for preliminary precipitation and filtration, and then enters the spraying device for spraying. At the same time, a compound packing layer is arranged in the tower body, and the water sprayed by the spraying device and the air flow of the induced draft device are convectively cooled, thereby improving the combination effect of wind and circulating water, thereby improving the heat dissipation capacity of circulating water and improving the heat dissipation efficiency of circulating water.
