Steel-structure hyperbolic air cooling tower

Abstract

Provided is a steel-structure hyperbolic air cooling tower. The outer contour of a steel netty supporting structure is a single-leaf hyperbolic rotating surface, a barrel formed by aluminum skin is installed in the steel netty supporting structure, the outer contour of the barrel is also a single-blade hyperbolic rotating surface, and multiple layers of radial tension steel cables are installed in the hyperbolic barrel. Each radial tension steel cable is composed of a center tension ring, steel cables, first steel cables and pins; each center tension ring is an annular component and comprises an upper tension annular plate and a lower tension annular plate, an annular web is fixedly connected between each upper tension annular plate and the corresponding lower tension annular plate, and the peripheral cylindrical surface of each annular web is fixedly connected with pulling plates at equal angles; one end of each steel cable is fixedly connected with the corresponding first steel cable, each first steel cable is hinged to the corresponding pulling plate through a pin, the other end of each steel cable is fixedly connected with a second steel cable, and the second steel cables are connected to the steel netty supporting structure. According to the steel-structure hyperbolic air cooling tower, the problems that for an ultra-large type hyperbolic air cooling tower, vibration resistance is weak, the tower height is limited, and the heat exchange performance is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of heat exchangers, and in particular relates to a steel structure hyperbolic air cooling tower. Background technique [0002] In power plant equipment, the steam turbine is the most widely used prime mover in modern thermal power plants and nuclear power plants. It is a machine powered by steam. After the superheated steam with thermal potential energy is introduced into the steam turbine through the pipeline, the high-speed flowing steam drives the rotor of the steam turbine to rotate, thereby converting the thermal potential energy into mechanical energy. The steam that releases heat energy is discharged from the exhaust port, which is called heat medium. The heat medium is a kind of unpolluted low-temperature steam. It is softened water obtained by heating, vaporizing and working on tap water. This kind of softened water has high purity and does not contain any impurities, so i...

Problems solved by technology

However, the height of the cooling tower is as low as 150m, and its own rigidity is poor, so it is difficult to resist harsh weather such as strong winds and earthquakes. At the same time, it follows the reinforcement ring inside the reinforced concrete cooling tower, which greatly reduces its thermal performance
