Water-collecting tank of high-level water-collecting cooling tower

Abstract

The invention discloses a water-collecting tank of a high-level water-collecting cooling tower. The top of the inner wall extends to the oblique upper side in a direction forming an angle alpha with the horizontal direction; a stream guidance water baffling plate is positioned on the top of the outer wall; the stream guidance part of the stream guidance water baffling plate extends along the same direction as the extending direction of the top of the inner wall; the angle between the stream guidance part of the stream guidance water baffling plate and the horizontal direction is beta; the angle beta is more than or equal to the angle alpha. The stream guidance water baffling plate is adopted by the water-collecting tank for guiding the air flowing through the water-collecting regions so as to reduce the partial loss of the air in flowing through the water-collecting regions, reduce resistance, as well as enable the cooling water to fully enter the water-collecting tank after flowing through a water-collecting sloping plate so that the water splashing to the outer side of the water-collecting tank is avoided.

Description

technical field [0001] The invention belongs to the field of thermal power generation and atomic energy power generation, and in particular relates to a technology capable of reducing the resistance of the water collection area of ​​a high-level water collection cooling tower, thereby reducing the ventilation resistance of the entire tower, increasing the ventilation volume of the entire tower, and reducing the temperature of the tower water . Background technique [0002] The high-level water collection cooling tower cancels the sump at the bottom of the conventional wet cooling tower, greatly shortens the range of the rain area, and installs a water collection device above the air inlet in the tower. The circulating water flows through the packing and is cooled and then collected by the water collecting device placed at the bottom of the packing. The circulating water collected by the water collecting device is collected into the catchment ditch, then transported to the ci...

AI Technical Summary

Problems solved by technology

This patent mainly has the following defects: the structure of the water collecting device is not optimized, so that the local loss of the airflow passing through the water collecting device is relatively large, resulting in relatively large resistance

Moreover, the patent only proposes the anti-splash effect, and does not solve the problem that the circulating cooling water may flow out of the sump when it flows downward through the sloping water collection plate
