Abstract

The invention discloses a winter anti-freezing and wind energy recovery system for an indirect air cooling power station. The winter anti-freezing and wind energy recovery system for the indirect air cooling power station comprises a natural ventilation indirect air cooling tower and an air cooling radiator, the air cooling radiator is positioned at a bottom air inlet of the natural ventilation indirect air cooling tower, and the winter anti-freezing and wind energy recovery system for the indirect air cooling power station further comprises a vertical shaft wind generating set and a generating set support column; and the generator set support column is located at the center position in the natural ventilation indirect air cooling tower, the vertical shaft wind generating set is installed on the upper portion of the generator set support column, and the height of the vertical shaft wind generating set is lower than the top of the natural ventilation indirect air cooling tower and close to the throat portion of the natural ventilation indirect air cooling tower. According to the winter anti-freezing and wind energy recovery system for the indirect air cooling power station, the vertical shaft wind generating set is additionally arranged in the cooling tower to increase the airflow resistance in the cooling tower, so that the air speed of the air inlet of the cooling tower is reduced, the heat exchange amount is reduced, and the anti-freezing purpose of the air cooling radiator is achieved.

Description

technical field [0001] The invention relates to a winter antifreeze and wind energy recovery system for an indirect air-cooled power station, belonging to the technical field of power station air-cooling towers. Background technique [0002] Circulating water natural draft cooling towers in thermal power plants and nuclear power plants are large thin-shell structures. For power plants built in areas with insufficient water sources, in order to save water, it is necessary to build a circulating cooling water system so that the hot water discharged from the cooler can be reused after being cooled in it. Most of the cooling structures used in large power plants are hyperbolic cooling towers. This type of cooling tower is mostly used in inland hydropower stations. [0003] Indirect air cooling technology is widely used in inland arid areas of my country because of its significant water-saving advantages. Since the cooling capacity of the air in winter exceeds the heat load of...
