Ultra-large dry and wet rain area cooling tower capable of actively adjusting dry area coverage area

Abstract

The invention relates to an ultra-large dry and wet rain area cooling tower capable of actively adjusting the dry area coverage area. A water distribution system and splitter plates are sequentially arranged on the lower portion of the ultra-large dry and wet rain area cooling tower from top to bottom, one end of each splitter plate is located on the tower barrel wall of the cooling tower, and the other end of each splitter plate points to the center of the radial section of the cooling tower. The splitter plates are connected with the tower wall through a transmission shaft which points to the tower wall from the radial center of the cooling tower. The mounting angle of the splitter plates can be actively adjusted, the splitter plates with the actively-adjusted mounting angle can change the coverage area of the dry area in real time according to the corresponding relation between different environments and operating parameters of the cooling tower and the optimal coverage area of the dry area, and it is ensured that the cooling tower is located at the optimal efficiency point when the working condition of the cooling tower is changed.

Description

technical field [0001] The invention relates to the field of energy and power engineering, in particular to a super-large cooling tower for dry and wet rain areas that actively adjusts the coverage area of ​​the dry area. Background technique [0002] The natural draft wet cooling tower has the advantages of high cooling efficiency, simple structure, safety and reliability, etc., and is widely used in thermal (nuclear) power plants and large-scale industrial systems that need to be cooled. The efficiency of the cooling tower directly affects the stability, efficiency and safety of the circulation system. [0003] The structure of conventional counterflow natural draft wet cooling tower mainly includes rain zone, fill, water distribution system and eliminator. The bottom diameter and circulating water volume of large or even super-large cooling towers are very large, which will inevitably increase the air intake resistance, making it difficult for the cold air from the outsi...

AI Technical Summary

Problems solved by technology

The bottom diameter and circulating water volume of large or even super-large cooling towers are very large, which will inevitably increase the air intake resistance, making it difficult for the cold air from the outside to reach the center of the tower, resulting in uneven radial distribution of the flow field of the cooling tower and reducing the overall cooling capacity. The ventilation rate of the tower seriously affects the heat exchange capacity of the cooling tower
