Abstract

The invention provides a fresh air supply system for a cooling tower and belongs to the field of thermal power generation or nuclear power generation, in particular to technology capable of realizing fresh air supply to the inside of a natural draft counter-flow wet cooling tower. The fresh air supply system of the cooling tower adopts an air duct structure, is arranged at the bottom periphery of the cooling tower and extends to central area of the tower opening from the outer edge of the air inlet of the cooling tower. Each air duct forms a certain inclination angle with the direction of a circumferential tangent and a certain inclination angle with a radial direction. Thus, the fresh air can be led into the cooling tower, the cooling efficiency of the cooling tower is improved, the internal air dramatic field in the cooling tower is improved, the optimal matching between the water flow distribution rules and the air distribution rules is realized and the temperature of circulating water is reduced.

Description

technical field

[0001] The invention belongs to the fields of thermal power generation and atomic energy power generation, and in particular relates to a technology capable of realizing supplementary fresh air inside a natural ventilation counterflow wet cooling tower. Background technique

[0002] The counterflow wet cooling tower currently in use has a hyperbolic shape with natural ventilation at the bottom. Circulating water enters the filling layer of the cooling tower and flows downward, and air flows upward from the bottom inlet to absorb the heat of circulating water, complete the process of heat transfer and mass transfer, and reduce the temperature of circulating water. With the increasing volume of cooling towers, the diameter of the air inlet has exceeded 100 meters. In this way, the aerodynamic field inside the cooling tower becomes extremely uneven, causing the heat transfer effect in the central area of ​​the cooling tower to weaken. The distribution law of t...
