Problems solved by technology

Although this can increase the ventilation volume and increase the cooling load of the cooling tower, under certain working conditions, such as high temperature, high humidity environment, high side wind, etc., it still cannot meet the cooling requirements, which affects the normal operation of the main engine
In addition, the long-term full-load operation of the booster fan also increases power consumption

Abstract

The invention relates to a natural ventilation cooling tower with a cooperate effect of internal power-assisted fans and a comprehensive synergy technology. The natural ventilation cooling tower comprises a tower body of the cooling tower and a dehydrator in the tower, and the power-assisted fans are arranged above the dehydrator. The operation manner, the arrangement manner, the arrangement number and the like of the power-assisted fans in the tower and the operation condition of the cooling tower are optimally controlled, and four synergistic structures are combined with the fans for use: (1) the power-assisted fans are combined with an air inlet air guide plate; (2) the fans are combined with a rain area air guide pipe; (3) the fans are combined with a rain area cross partition wall; and (4) the fans are combined with the optimized arrangement of filler. In the specific implementation process, according to the specific form of the cooling tower, one or more specific structures can be used at the same time, and all the four specific structures can be used at the same time. According to the technology, the ventilation quantity of the cooling tower can be increased, the uniformityof an aerodynamic field in the tower is improved, the adverse effect of crosswind is reduced, the cooling load of the cooling tower is greatly increased, the requirement for the cooling effect of thecooling tower after the load of the cooling tower is increased is met, and meanwhile the power consumption of the power-assisted fans can be reduced.

Description

technical field [0001] The invention belongs to the technical field of cooling towers, and in particular relates to a natural ventilation cooling tower with synergistic effects of an internal booster fan and a comprehensive synergistic technology. On the basis of setting a booster fan inside the cooling tower and optimizing its operation, an air deflector and an air guide pipe are adopted. Some efficiency-enhancing technical measures, such as the cross partition wall and the optimized packing arrangement, work together with the booster fan to complete the cooling capacity increase of the cooling tower and improve the cooling efficiency. It can be used for new natural draft cooling towers, and can also be used for the transformation of existing natural draft cooling towers. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily ...
