Description

1. Technical field

[0001] The invention belongs to the cold protection technology of cooling towers, and in particular relates to a winter cold protection method for an air inlet at the lower part of a hyperbolic cooling tower. 2. Background technology

[0002] The cooling tower of the power plant enters the winter operation period when the winter temperature reaches below -10°C. In order to prevent freezing damage to the cooling tower system, winter cold protection measures must be taken for the air inlet at the lower part of the tower. The current specific methods are: hanging the windshield; increasing the water distribution of the outer ring of the sprinkler device; artificially breaking ice, etc. The above methods are very inflexible, time-consuming and laborious, and have poor thermal insulation effect, so it is difficult to ensure the cooling effect of the cooling tower. Due to the variable temperature and large temperature difference in winter, it is difficult to ma...
