Anti-freezing and heat exchange optimized structure of natural ventilation cooling tower of thermal power plant

Abstract

The invention discloses a thermal power plant natural ventilation cooling tower anti-freezing and heat exchange optimized structure, and particularly relates to the technical field of cooling tower anti-freezing, the thermal power plant natural ventilation cooling tower anti-freezing and heat exchange optimized structure comprises two semi-annular bottom plates, the two semi-annular bottom plates are spliced into a ring, and semi-annular top plates are arranged at the tops of the two semi-annular bottom plates; the two semi-annular top plates can be spliced into a ring, a plurality of wind shielding canvas curtains are arranged between the semi-annular top plates and the semi-annular bottom plates, a plurality of vertical rods are fixedly arranged at the tops and the bottoms of the wind shielding canvas curtains, and pulleys are fixedly arranged at the ends, away from the wind shielding canvas curtains, of the vertical rods. The multiple wind shielding canvas curtains and the multiple flow guiding air plates are installed between the semi-annular bottom plate and the semi-annular top plate, crosswind and warm keeping can be achieved by adjusting the shielding area of the wind shielding canvas curtains and the opening angles of the flow guiding air plates, and control over the wind shielding canvas curtains and the flow guiding air plates can be achieved remotely; therefore, manpower resources can be saved, and personal injury accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of cooling tower antifreeze, in particular to an antifreeze and heat exchange optimization structure of a natural ventilation cooling tower of a thermal power plant. Background technique [0002] With the introduction of policies such as energy saving and emission reduction and the restriction of my country's energy structure, hydropower, wind power, nuclear power and photovoltaic power generation and other forms of power generation have developed rapidly, and their installed capacity has increased rapidly. It will be dominated by thermal power generation. [0003] As can be seen from the flow chart of the water circulation system of a thermal power plant, the cooling tower occupies an important position in the entire circulation system. The thermal power plant contains two sets of water circulation systems: one is the working medium water circulation process in the steam-water system: the circulating water ...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the present invention provides a natural ventilation cooling tower antifreeze and heat exchange optimization structure of a thermal power plant. The shading area of ​​the sail curtain and the opening angle of the deflector windshield can keep the side wind and keep warm, and the control of the windshield canvas curtain and the deflector windplate can be realized remotely, thus saving human resources and avoiding personal injury Accidents, to solve the problems in the prior art that cannot block the crosswind and easily cause personal injury accidents due to the artificial suspension of the windshield
