Non-uniform packing system for high-level water recovery cooling tower

Abstract

The invention discloses a non-uniform packing system for a high-level water recovery cooling tower. The non-uniform packing system for the high-level water recovery cooling tower comprises a packing area, wherein the packing area is located in the cooling tower. Non-uniform arrangement and partition arrangement are adopted by packing in the packing area. According to the partition mode of the packing area, the vertical axis of the cooling tower serves as the center, three annular regions including the region A, the region B and the region C are formed outwards in sequence, wherein the radii of the three annular regions are different. According to the relation of the radii of the packing in the three packing regions, the radius of the packing in the region A is smaller than or equal to that of the packing in the region B and that of the packing in the region C, and the radius of the packing in the region B is smaller than or equal to that of the packing in the region C. According to the relation of the thicknesses of the packing in the three packing regions, the thickness of the packing in the region A is larger than or equal to that of the packing in the region B and that of the packing in the region C, and the thickness of the packing in the region B is larger than that of the packing in the region C. According to the non-uniform packing system for the high-level water recovery cooling tower, non-uniform arrangement of the packing in the regions of the high-level water recovery cooling tower is adopted, the gas-water ratio in the tower can be increased to the maximum extent, the cooling performance of the packing in the tower is fully utilized, and the cooling efficiency of the 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 packing system adopted for improving the cooling efficiency of a high-level water collection cooling tower. Background technique [0002] The use of high-level water-receiving cooling towers is increasing day by day in China. At present, the conventional design of domestic high-level water-receiving cooling tower packing is that the packing is evenly arranged on the water collecting device in the tower, and the same height is arranged at different radii. However, the cooling tower has a large volume and a huge filling area. The huge filling area is difficult to ensure the reasonable distribution of the aerodynamic field in the filling area. The air around the filling area is insufficient, resulting in a low air-water ratio and low cooling capacity; There is still a gap in the wet bulb temperature of the extreme ambi...

However, the cooling tower has a large volume and a huge filling area. The huge filling area is difficult to ensure the reasonable distribution of the aerodynamic field in the filling area. The air around the filling area is insufficient, resulting in a low air-water ratio and low cooling capacity; There is still a gap in the wet bulb temperature of the extreme ambient air, and there is still room for improvement in the air-water ratio, the cooling capacity is not fully utilized, and the cooling efficiency 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 and equal-height arrangement of packing, and the cooling capacity of the packing in the tower is not fully utilized. The air in the tower Uneven distribution and low cooling efficiency

[0004] In the patent [201210085960.3], a kind of arrangement method of wet cooling tower filler is disclosed. This arrangement method is to arrange the filler in the wet cooling tower non-uniformly through the principle of air heat absorption and moisture absorption. This arrangement method is only for wet cooling tower. For cooling towers, if this kind of non-uniform arrangement is applied to the high-level water-receiving cooling tower, the cooling efficiency of the high-level water-receiving cooling tower will be further reduced, because there is no rain area in the high-level water-receiving cooling tower, and the air enters the tower through the air inlet. There is no process of heat absorption and moisture absorption. The principle of non-uniform packing arrangement of the high-level water-receiving cooling tower is essentially different from that of the wet cooling tower. Arranged evenly
