Description

Technical Field

[0001] The utility model belongs to the technical field of high-position water collection cooling towers, and more specifically relates to a water collection device for preventing floating dripping of a high-position water collection cooling tower. Background Art

[0002] At present, high-level water collection cooling towers are widely used in large-capacity thermal power units. The working principle of high-level water collection cooling towers is: circulating water (hot water) enters the water distribution device through the central shaft and is sprayed through the nozzle. When the spraying water flows through the filler, it exchanges heat with the air and transfers the heat of the circulating water to the atmosphere; the cooling water falling from the bottom of the filler is intercepted, guided, and collected in the central water collection tank above the air inlet by the high-level water collection device, and finally sent to the condenser through the circulating water pump to cool the turbine exhaust.

[0003] The high-level water collection device is mainly composed of a U-shaped water trough, a water collection inclined plate, etc. The cooled circulating water is collected by the water collection inclined plate and enters the U-shaped water trough, and finally flows into the water collection tank.

[0004] However, in the process of water spraying, water droplets hit the water collecting inclined plate, which will produce splashing drops. Some of the drops cannot be collected into the U-shaped water tank, but float to the ground from the gaps between the U-shaped water tanks, which makes this part of the water wasted. And as the temperature and unit load drop, the cooling tower suction force decreases, the air velocity and flow rate decrease, and more drops will be generated. Some drops adhere to the outer wall of the U-shaped water tank and the high-position water collection cooling tower column, and ice will be formed in winter, affecting the safe operation of the high-position water collection cooling tower. Utility Model Content

[0005] The utility model aims to provide a water collecting device for preventing drifting and dripping of a high-position water collecting cooling tower, so as to fundamentally reduce the splashing generated when circulating water is sprinkled in the high-position water collecting cooling tower, thereby achieving multiple effects such as preventing drifting and dripping, saving water and preventing freezing.
