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

Embodiment 1

[0035] Such as Figure 1-4 As shown, the cooling tower in the dry and wet rain area is used to adjust the coverage area of ​​the dry area by using the water potential energy of the rain area. One end of the splitter plate is located on the tower wall 3 of the cooling tower, and the other end points to the center of the radial section of the cooling tower. All the splitter plates are rotationally symmetrical about the center of the radial section of the cooling tower.

[0036] The cooling tower is a natural ventilation counter-flow wet cooling tower with dry and wet rain areas, and its conventional structure includes a water eliminator 11 at the top of the water distribution system 1, a filler 12 at the bottom of the water distribution system 1, and a dry and wet rain area.

[0037] A conventional cooling tower with a rain zone adds a splitter plate 2 to form a dry and wet rain zone cooling tower in the rain zone, where the area covered by the splitter plate 2 is the dry zone 6...

Abstract

The invention relates to a dry and wet rain area cooling tower capable of adjusting the coverage area of a dry area by using water spraying potential energy of a rain area. A water distribution system and splitter plates are sequentially arranged at the lower part of the ultra-large type dry and wet rain area cooling tower from top to bottom, and a water spraying potential energy utilization assembly is arranged below the water distribution system. One end of each splitter plate is located on the tower wall of the cooling tower, the other end of each splitter plate points to the radial section center of the cooling tower, the splitter plates are connected with the tower wall through transmission shafts, and the transmission shafts point to the tower wall from the radial center of the cooling tower. Potential energy generated by spraying water in the rain area of the cooling tower can be converted into electric energy to supply power to the angle adjusting process of the splitter plates by utilizing a hydraulic impeller located below filler, and extra electric energy is not consumed on the basis of improving the cooling efficiency of the cooling tower.

Description

technical field [0001] The invention relates to the field of energy and power engineering, in particular to a cooling tower in a dry and wet rain area for adjusting the coverage area of ​​a dry area by utilizing the water potential energy of a rain 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 difficul...
