Air cooling tower with internal *-shaped rectifying device

Abstract

The invention discloses an air cooling tower with an internal *-shaped rectifying device. The air cooling tower comprises a tower drum, a radiator and the *-shaped device, wherein the *-shaped device is divided into a first rectifying module, a second rectifying module, a third rectifying module, a fourth rectifying module, a fifth rectifying module, a sixth rectifying module, a seventh rectifying module and an eighth rectifying module in the circumferential direction of the air cooling tower, the first rectifying module, the fifth rectifying module, the third rectifying module and the seventh rectifying module are connected through connecting devices to form a cross wall structure, the inner ends of the second rectifying module, the fourth rectifying module, the sixth rectifying module and the eighth rectifying module are in a certain radial distance from the center of the air cooling tower, and the outer end of each rectifying module is in a certain radial distance from an inner ring of the radiator. On the basis of the *-shaped device, the transverse impact of tower entering air on the windward side to air entering a leeward area can be reduced, and the air input on the leeward side is increased; compared with a traditional cross wall, transverse flowing of the tower entering air on the windward side can be reduced, the air is guided to flow upwards, and the effect of in-tower rectifying is achieved; and meanwhile, gaps are reserved at intervals in the inner ends of the rectifying modules to play a role in equalizing pressure, and the adverse effect on the inflow air as a result of increase of half-tower pressure on the windward side due to blocking by the rectifying device is reduced.

Description

technical field [0001] The invention belongs to the field of air-cooling towers of thermal / nuclear power plants, in particular to an air-cooling tower with a meter-shaped rectification device inside. Background technique [0002] Air and cooling water conduct indirect heat exchange in the radiator of the air-cooling tower to realize the cooling treatment of circulating cooling water. The radiator is the core component of the air-cooling tower, and its stability and efficiency determine the cooling efficiency of the air-cooling tower. When the air-cooling tower encounters In windy weather, the air on the windward side of the tower passes through the radiator at a relatively high wind speed. At this time, the laterally flowing air has an adverse effect on the heat exchange of the radiator on the leeward side. cooling performance. [0003] China's patent application, application number 201710480509.4, discloses an indirect air cooling tower, including: a central deflector and ...
