Abstract

The invention discloses an indirect cooling tower with petal-shaped cooling triangle distribution. The indirect cooling tower comprises vertical cooling triangles circumferentially distributed at the outer edge of the bottom diameter of a tower drum, vertical cooling triangles radially distributed in the tower drum, vertical cooling triangles circumferentially distributed in the tower drum, and horizontal cooling triangles. After the structure is adopted, cold air and hot air alternation areas and a central hot-air area are formed within the height of an air inlet of the tower. The indirect cooling tower disclosed by the invention has the following advantages that (1) the enough cooling triangles are distributed in the limited space, and the resistance of cold-air flow for passing each cooling triangle is not increased; (2) under the premise of the fixed total area, the diameter of the indirect cooling tower can be greatly reduced, so that the cost can be reduced; and (3) the flow field and the temperature field in the tower is relatively uniform, and the air density difference inside and outside the tower is relatively large.

Description

technical field

[0001] The invention relates to the field of energy and power engineering, in particular to an indirect cooling tower arranged in a triangular petal shape. Background technique

[0002] On September 12, 2014, the National Development and Reform Commission issued a notice on the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)", which clearly stipulates the power supply that must be achieved by various coal power units in 2020. Coal consumption indicators, coal power units are under great pressure to save energy.

[0003] The indirect cooling tower (hereinafter referred to as the indirect cooling tower) is located at the cold end of the thermodynamic cycle of the air-cooling unit, and its working performance directly affects the vacuum of the condenser and the coal consumption of power supply. The data shows that every time the water temperature at the outlet of the cooling tower decreases by 1°C, the...
