An active flow field reconstruction air cooling tower

Abstract

The invention discloses an active flow field reconstruction air-cooling tower, comprising: a tower body; a radiator located at the bottom of the tower body; a flow guiding device arranged outside the radiator; The radial direction of the radiator extends outward from the radiator; the back plate has a concave portion, the opening of the concave portion faces the radiator, and the wind deflector is partially located in the concave portion; the cover plate is arranged above the wind deflector and the back plate, and the two ends of the cover plate are respectively It is connected with the top of the back plate and the tower body, and the wind deflector, the back plate and the cover plate form a guide channel; the back plate includes a first louver, and the blades of the first louver extend in the vertical direction; The opening degree of the first louver is controlled; the application of the above-mentioned active flow field reconstruction air cooling tower can improve the adaptability of the flow field reconstruction device to different wind directions.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to an active flow field reconstruction air cooling tower. Background technique [0002] As an efficient, water-saving and environmentally friendly thermal power generation technology, air-cooled power generation has developed rapidly in the world's power construction in recent years, especially in countries and regions with relatively scarce water resources, the technology is more and more widely used. In addition, the indirect air-cooling system in air-cooling technology has gradually gained recognition in the power industry due to its noise-free air-cooling tower, long life, simple maintenance, and energy saving. The air cooling tower uses the natural buoyancy movement generated by the air through the surface heat exchanger to take away heat, which makes its cooling efficiency greatly affected by the ambient wind conditions, especially the lateral natural wind. The indir...

Problems solved by technology

Therefore, if the indirect air cooling system is not improved and optimized, it is easy to cause the back pressure fluctuation of the steam turbine to be too large, which will have a great impact on the cycle efficiency of the indirect air cooling unit, and in serious cases, the indirect air cooling unit will not be able to operate at high load or full load Setting will cause downtime of indirect air-cooled units

[0003] In view of the above problems, a better solution is to install at least one set of deflectors in the circumferential direction of the air-cooling tower to strengthen the air intake effect of the radiator behind the windshield and improve the ventilation characteristics of the air-cooling tower; however, the above-mentioned deflectors The position of the device is fixed. When the wind direction changes, the setting cannot be changed with the wind, which limits the effect of flow field reconstruction; The heat dissipation effect of the air cooling tower
