Problems solved by technology

The study found that after the water tower was equipped with guide plates, although the cooling efficiency of the cooling water tower has been improved, there is still a high-humidity and high-temperature air zone in the central area of ​​the water tower. The cooling efficiency of this area is significantly lower than other areas, indicating that the water tower The cooling efficiency has the potential to improve

Embodiment 1

[0024] The air-conditioning device in the central area of ​​the natural ventilation cooling water tower comprises: a water tower 2 equipped with a guide plate 1; Between the adjustment devices is the air adjustment channel 3 . The lower part of the channel communicates with the air area of ​​the lower part of the filler, and the upper part is connected with the upper part of the water distribution system of the filler, and the channel is connected with the air conditioning device 5 . The packing area includes packing, sprinkler, water distribution system and water eliminator.

Embodiment 2

[0026] In the air-conditioning device in the central area of ​​the natural ventilation cooling tower above, the horizontal section of the channel is circular or polygonal, or the channel is realized by pipes of various shapes.

Embodiment 3

[0028] The method for air conditioning in the central area of ​​the natural ventilation cooling water tower is to install an air conditioning device on the air conditioning channel in the central area of ​​the water tower core, and the air conditioning device and the top of the air conditioning channel to adjust the diameter of the baffle The gap of 5% to 45% is used to adjust the air flow and speed. The air conditioning device and the passage correspond to a spherical crown or a streamlined adjustment baffle; or a hollow round platform is installed on the air conditioning channel, and a coaxial adjustment baffle is installed above the hollow round platform; Or adopt on the air channel, coaxially install two unequal height cones (the upper part can also be designed as a peach-shaped streamlined body or a truncated cone). The basic mode of the air conditioning device is to install a hollow cylinder or round tube coaxially on the air channel, and install a hollow cylinder or rou...

Abstract

The invention relates to a central area air conditioning device of a natural draft cooling water tower and a conditioning method. The cooling efficiency of the prior water tower has the potential to improve. The central area air conditioning device of the natural draft cooling water tower comprises a water tower (2) additionally provided with a guide board (1); the air conditioning device (5) is arranged in a filling area (4) at the center of the water tower; and an air conditioning passage (3) is formed between the filling area and the air conditioning device. The central area air conditioning device is used for the air conditioning of a power plant cooling water tower.

Description

Technical field: [0001] The invention relates to the technical fields of thermal power generation and atomic power generation engineering, in particular to an air conditioning device and an adjusting method for the central area of ​​a natural ventilation cooling water tower. Background technique: [0002] Naturally ventilated wet counterflow cooling towers are equipment for cooling circulating water in thermal power plants and nuclear power plants. Generally, the hyperbolic rotating shell (tower) mode is adopted, and the shell is supported by herringbone columns evenly distributed along the circumference at the bottom. The top of the herringbone column is connected to the ring beam of the shell, and the bottom is supported by the ring base. A pool wall for retaining water is built on the ring base to form a sump. The tower core is composed of sprinkler frame, sprinkler filler, water distribution system, water eliminator and other components in the shell. The space formed ...
