Non-uniform water distribution system for high-position water collecting cooling tower

Abstract

The invention discloses a non-uniform water distribution system for a high-position water collecting cooling tower. The non-uniform water distribution system comprises a water distribution area located in the cooling tower, the water distribution of the water distribution area is in non-uniform arrangement and zoning arrangement; that is to say, a non-uniform arrangement mode is adopted from inside to outside in the diameter direction of the high-position water collecting cooling tower. The zoning mode of the water distribution area is that with the vertical axis of the cooling tower as the center, the water distribution area is sequentially divided into three annular areas of different radiuses outwards, and the three annular areas are an area A, an area B and an area C. The non-uniform water distribution system reduces the influence on air uniformity in the tower caused by water spraying density, the cooling capability in the tower is fully utilized, and the cooling efficiency of the high-position water collecting cooling tower is improved.

Description

technical field [0001] The invention belongs to the fields of thermal power plants and atomic energy power generation, and in particular relates to a non-uniform water distribution system of a high-level water-receiving cooling tower for improving the cooling efficiency of the high-level water-receiving cooling tower. Background technique [0002] The use of high-level water-receiving cooling towers is increasing day by day in China. At present, the water distribution system of high-level water-receiving cooling towers is of conventional design, that is, the spraying water density is evenly distributed along the diameter of the water distribution surface. However, the cooling tower is huge and the space inside the tower is huge. After the ambient wind enters from the air inlet at the bottom of the cooling tower, the flow velocity distribution in the tower is uneven. At the same time, due to the influence of the uniform distribution of the spraying water density, the aerodynam...

Problems solved by technology

However, the cooling tower is bulky and the space inside the tower is huge. After the ambient wind enters from the air inlet at the bottom of the cooling tower, the flow velocity distribution in the tower is uneven. At the same time, due to the influence of the uniform distribution of the spraying water density, the aerodynamic field in the tower is destroyed again. Distribution, so that the cooling capacity of the cooling tower is not fully utilized, the air-water ratio is low, and the cooling efficiency of the cooling tower is low

[0003] In the patent [201310132397.5], a high-level water collection device and a wet cooling tower containing the device are disclosed. The high-level water collection cooling tower adopts a uniform water distribution method, and the aerodynamic field in the tower is greatly damaged and distributed unevenly. Underutilized capacity, low air-to-water ratio, and low cooling efficiency
