Problems solved by technology
[0005] In order to solve the problem of large investment in existing Kazakh towers, the present invention provides an air guide shaft for a high-level water collection cooling tower and its cooling tower. Under the premise of the path of falling water in the rain area and only changing the rising path of the air, the goal of high-level water collection can be achieved, and the construction cost of the high-level water collection cooling tower can be reduced

Embodiment 1
[0072] The 1000MW generator set of Guangdong Heyuan Power Plant is equipped with Harbin towers. By adopting the high-level water-receiving cooling tower of the present invention, each cooling tower can save 31.58 million yuan. The cost of the sunken cylindrical pool is 18.17 million yuan. Therefore, cooling tower of the present invention is also compared with building 12000m in Heyuan Power Plant 2 The conventional tower saves investment of 8.84 million yuan.
[0073] A high-level water collection cooling tower of the present invention, compared with the existing high-level water-collection cooling tower, the high-level tower is equipped with a high-level water collection tank, the high-level water collection device is canceled, and the existing rectangular water collection pool is modified into a cone bucket pool, reducing In order to reduce the construction cost, the shaft body passes through the cone bucket pool from bottom to top, and a water shielding cap is installed on...

The invention provides an air guide well of a high-altitude water collection cooling tower and a cooling tower thereof. The air guide well comprises a shaft body; the lower end of the shaft body penetrates through a taper hopper pool, and is connected with a foundation; a water shielding cap is arranged at the upper end of the shaft body; cooling air enters through the lower part of the shaft body, and is guided out by the water shielding cap for cooling fillers in the cooling tower; meanwhile, the shaft body and the taper hopper pool achieve a mutual supporting effect to improve the stabilityof the air guide well and the taper hopper pool; secondly, the water shielding cap is arranged at the top of the shaft body to prevent water from entering the shaft body to realize water-vapor separation; and finally, a support column is arranged at the top of the shaft body, and is connected with a filler beam and a dehydrator beam to achieve a supporting effect on the filler beam and the dehydrator beam and to improve the utilization rate of upper space.
Description
technical field [0001] The invention belongs to the field of wet cooling towers of thermal (nuclear) power plants, and in particular relates to an air guide shaft of a high-level water collection cooling tower and a cooling tower thereof. Background technique [0002] The world's first high-level water-receiving cooling tower designed by the Belgian company Hamon was put into operation at the Belleville Nuclear Power Plant in France in 1986. This kind of cooling tower can be referred to simply as "Hagao tower" to distinguish it from "conventional tower". [0003] my country's first "Hagao Tower" was put into operation in Shaanxi Pucheng Power Plant in March 1996. Compared with conventional towers, Hagao Tower has the remarkable advantages of energy saving, noise reduction and cold wind reaching the center of the tower. Since 2012, the thermal power plants that have been put into operation in my country include Anqing, Wanzhou, Laiwu, Shouguang, Jiujiang, Hefei Lujiang, Rui...
