Supporting structure of indirect air cooling tower with high air inlet

Abstract

The invention discloses a supporting structure of an indirect air cooling tower with a high air inlet. The problems of air resistance area increase and construction cost increase caused by the high air inlet are solved. The supporting structure comprises cross column supporting piers (2) arranged on an annular concrete foundation base (1) at equal intervals in an arc-shaped mode, wherein a left oblique concrete supporting column (3) and a right oblique concrete supporting column (4) are arranged on each of the cross column supporting piers (2) respectively, the left oblique concrete supportingcolumn (3) and the right oblique concrete supporting column (4) are arranged in a V-shaped mode, and a tower-cylinder annular beam (5) is arranged between the top end of the left oblique concrete supporting column (3) and the top end of the right oblique concrete supporting column (4). By changing one intersection point in an X-shaped supporting column into two intersection points, the calculation length of each supporting column is decreased, the cross-section area of each supporting column is decreased on the premise that the requirements for standard length-thickness ratio and shaft-pressure ratio are met, the construction costs are reduced, and the air resistance area of the tower is decreased.

Description

technical field [0001] The invention relates to a supporting structure of an indirect air-cooling tower of a thermal power plant, in particular to a supporting structure of an indirect air-cooling tower with a high air inlet which is suitable for dissipating heat from an ultra-high air-cooling radiator. Background technique [0002] Due to the constraints of natural conditions and the acceleration of urbanization, the construction land used for power plant projects tends to be tight, and the cooling system of thermal power plants is required to occupy less and less land, while the generator sets are getting larger and larger. These factors directly lead to air cooling. Radiator heights are getting higher and higher. In a thermal power plant, the concrete cooling tower constructed is mainly composed of a circular concrete foundation, a pier, an X-shaped cross column and a tower. The diameter of the tower and the height of the X-shaped cross column determine the air intake of ...

AI Technical Summary

Problems solved by technology

In a thermal power plant, the concrete cooling tower constructed is mainly composed of a circular concrete foundation, a pier, an X-shaped cross column and a tower. The diameter of the tower and the height of the X-shaped cross column determine the air intake of the cooling tower; The supporting structure of the indirect air-cooling tower is composed of circular concrete foundation, column piers, X-shaped cross columns and the lower ring beam of the tower. An air-cooling radiator is arranged on the outer ring of the supporting structure. The height of the X-shaped cross column in the supporting structure of the tuyere increases accordingly, which directly leads to an increase in the cross-section of the X-shaped cross column, which increases the wind resistance area of ​​the cooling tower and affects the air intake of the cooling tower and the air cooling system. thermal performance and increase the engineering cost of the supporting structure
