Abstract

The invention discloses a Heller type air cooling tower, which comprises a cooling unit and a heat dissipating unit; the cooling unit comprises an annular heat exchanger formed by a plurality of setsof cooling triangles arranged annularly and an air inlet structure, wherein the air inlet structure is arranged annularly, and the air inlet structure is arranged annularly and located at the outer ring of an annular heat exchanger; the heat dissipating unit comprises a double-curve cooling tower, which is located above the cooling unit, and the air inlet structure of the cooling unit is an air inlet diversion type air inlet structure: the air inlet diversion type air intake comprises a plurality of inlet air direction adjusting devices, and the inlet air direction adjusting devices comprise air inlets and an air inlet diversion plates, and the right sides of the air inlets are hinged with the air inlet diversion plates by a hinged structure; diversion plate positioning structures are arranged between the air inlets and the air inlet diversion plates, and the diversion plate positioning structure can position the air inlet diversion plates at different rotation angles. The Heller typeair cooling tower is applied to air cooling generator sets of large thermal power plants, which can improve the heat exchange efficiency of existing Heller type air cooling tower.

Description

technical field [0001] The invention relates to the technical field of air cooling equipment for thermal power plants. Background technique [0002] The air-cooling tower is an important part of the indirect air-cooling unit, and its performance directly affects the safe and economical operation of the air-cooling unit. The cooling efficiency of the cooling tower affects the temperature drop of the water tower and the temperature of the water leaving the tower, and the temperature of the water leaving the tower directly affects the efficiency of the generator set for a long time. In a windless state, the temperature of the air at each point inside the cooling tower is different, so once it is affected by the fluctuation of external natural wind (generally horizontal wind), the air in the tower will fluctuate and local parts will form vortices. Under the influence of ambient wind, it will weaken the smoothness of the air in the tower and reduce the ventilation volume of the ...
