Longitudinal-vortex-removing padding and high-position water receiving cooling tower

Abstract

The invention discloses longitudinal-vortex-removing padding and a high-position water receiving cooling tower. The longitudinal-vortex-removing padding and the high-position water receiving cooling tower are included; the longitudinal-vortex-removing padding comprises inner ring padding, middle ring padding and outer ring padding; the bottom of the middle ring padding protrudes downwards relativeto the bottom of the inner ring padding, the bottom of the outer ring padding protrudes downwards relative to the bottom of the middle ring padding, protrusions face a water receiving device, and thetops of the inner ring padding, the middle ring padding and the outer ring padding are flush; the high-position water receiving cooling tower is composed of a tower barrel, a water removal device, awater distribution system, the longitudinal-vortex-removing padding, a water receiving device and the like; the outer ring of the bottom of the padding protrudes downwards relative to the inner ring,generation space of a longitudinal vortex in the area of the outer ring water receiving device of the high-position tower is reduced, the longitudinal vortex of the air flow field of the area of the outer ring water receiving device of the high-position tower is reduced and even removed effectively, heat and medium transfer of the outer ring area of the high-position tower can be strengthened, thehigh-position tower thermal performance is improved, and important value in design optimization and system energy saving is achieved.

Description

technical field [0001] The invention relates to the fields of thermal power plants and atomic energy power generation, in particular to fillers capable of eliminating longitudinal vortices and high-level water-receiving cooling towers. Background technique [0002] The use of high-level water-receiving cooling towers (referred to as high-level towers) is increasing in China. With the construction of 1000MW large-scale power plant units in my country and the emphasis on circulating water and thermal pollution in coastal power stations, high-level water-receiving cooling towers have become the technical development of super large cooling towers. one of the new directions. Compared with conventional natural ventilation cooling towers, high-level water collection cooling towers use water collection devices for high-level water collection, which has the advantages of energy saving and noise reduction. Through the high-level water collection of the water collection device, the hig...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is the large longitudinal vortex in the area of ​​the peripheral water collection device below the filling of the high-level water collection cooling tower, especially under the condition of environmental crosswinds, the longitudinal vortex covers a plurality of air in the water collection area on the windward side of the high-level tower. flow channel, resulting in small ventilation above this area, poor heat and mass transfer, and the cooling performance of the high-level water collection cooling tower is correspondingly reduced
