Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] see figure 1 , 2 , 3 and 4, a hyperbolic steel structure cooling tower, including straight-line inclined columns, intersecting nodes and stiffening rings, the vertical line rotation array formed by the straight-line inclined columns around the center of the tower and the center of the lower circle constitutes the skeleton of the hyperbolic cooling tower , the intersections of straight and oblique columns are nodes, and along the height direction of the tower, three to five stiffening rings are arranged as required. The height of the tower exceeds 150m, and the diameter of the lower part is about 150m.

[0021] The straight-line oblique column is a round steel column or a square steel column with a cross-sectional diameter or side length between 500mm and 1000mm; it can also be a square lattice column made of angle steel or channel ste...

Abstract

The invention discloses a large double-curve steel structure cooling tower for a power plant. The large double-curve steel structure cooling tower comprises linear inclined vertical columns, intersected nodes and reinforcing rings, wherein a steel structure cooling tower framework consists of a vertical line rotary array formed by encircling the linear inclined vertical columns around an upper circle center and a lower circle center of the tower; intersected positions of the linear inclined vertical columns are the nodes; and along the height direction of the tower, 3 to 5 reinforcing rings are required to be arranged. The tower is over 150 meters high, and the diameter of the lower part of the tower is about 150 meters. The large double-curve steel structure cooling tower is a novel steel structure cooling tower replacing a concrete thin-shell double-curve cooling tower, is suitable for indirect cooling units with the capacities of 125 MW or over 125 MW, can be applied to those extremely cold places in which the concrete cooling tower cannot be used, and has the characteristics of low gravity, high construction speed, simple foundation treatment operation, low comprehensive manufacturing cost, high anti-seismic and anti-wind performance, low post-maintenance cost and the like.

Description

technical field [0001] The invention belongs to the technical field of large-scale cooling tower design for power plants, and relates to a large-scale hyperbolic steel structure cooling tower for power plants. Background technique [0002] In traditional thermal power plants, large-scale cooling towers basically use reinforced concrete thin-shell hyperbolic cooling towers. This structural type has been researched and practiced for many years, and has been applied in a large number of projects with good results. The research results of reinforced concrete thin-shell hyperbolic cooling towers are rich. At present, it is possible to design super-large towers with a diameter of more than 150m and a height of about 200m. [0003] With the development of technology and the diversification of owners, the cooling method of indirect cooling will be widely used in power plants in coal-rich and water-shortage areas, and the new structural type of steel structure hyperbolic cooling tow...
