Background

The cooling tower is one of important equipment in industrial production, and is a device for taking away waste heat generated in the industrial production process through circulating cooling water, and the safety and the economic benefit of the industrial production are directly influenced by the quality of the cooling performance of the cooling tower.

Cooling towers commonly used in current industrial production include conventional natural draft counter-flow wet cooling towers as shown in fig. 1, and mechanical draft counter-flow wet cooling towers (including single-sided and double-sided intake air) as shown in fig. 2. Waste heat generated in industrial production is transferred to circulating cooling water through a heat exchanger, the circulating cooling water with heat is conveyed to a water distribution system of a cooling tower through a circulating water pump, the circulating cooling water is uniformly sprayed to the top surface of a filler by the water distribution system, the circulating cooling water falls into a water collecting tank of the cooling tower after passing through a water spraying filler, in the process, the circulating cooling water and air entering the cooling tower are subjected to heat-mass exchange, damp and hot air subjected to the heat-mass exchange is discharged to the atmosphere from an outlet of the cooling tower, the cooled circulating water falls into the water collecting tank and then is continuously conveyed to the heat exchanger through the circulating water pump for heat exchange, and therefore the waste heat generated in the industrial production can be continuously discharged to the atmosphere.

The areas of the conventional natural draft cooling tower and the mechanical draft cooling tower for heat and mass transfer can be divided into 3 parts, including a spraying area (from a spray nozzle outlet to a filler top surface), a water spraying filler area and a water spraying rain area (from a filler bottom to a water collecting tank top surface), wherein the cooling capacities of different areas are different, the cooling capacity of the spraying area accounts for about 10% of the cooling capacity of the whole tower, the cooling capacity of the water spraying filler area accounts for about 80% of the cooling capacity of the whole tower, and the cooling capacity of the water spraying rain area accounts for about 10% of the cooling capacity of the whole tower.

In the mechanical ventilation counter-flow wet cooling tower with double-side air inlet, the height of the water-spraying rain area accounts for about 50 percent of the static lift of the cooling tower, and the size is 20m (long)For a mechanical ventilation counter-flow type wet cooling tower with double-side air intake of 20m (width) as an example, the air inlet is about 4.5m, the circulating water flow is 5000t/h, and for the mechanical ventilation counter-flow type wet cooling tower with single-side air intake, the height of the air inlet is as high as 6.5m under the same other parameters. In general, in industrial production, a plurality of unit cell mechanical draft cooling towers are often arranged in one row or a plurality of rows for use, and the circulating water flow is large. Therefore, although the existing cooling tower has high cooling capacity and large circulating water flow, the height of a water-sprinkling rain area is high, the water-sprinkling resistance is large, and in addition, the falling potential energy of water in the water-sprinkling rain area is wasted.
