Device capable of improving thermal performance of cooling tower

Abstract

The invention discloses a device capable of improving a thermal performance of a cooling tower. The device comprises a tower body and upper spraying nozzles arranged in the tower body; the upper part of the tower body is fixedly provided with a wind cylinder, a fan is arranged in the wind cylinder, a padding region is arranged on the bottoms of the sprayers, and equal-width fan blades and gas turbulators are arranged in the tower body. The novel extruded, drawn and sectioned equal-width fan blades are adopted in the cooling tower to replace traditional fan blades to increase a working area of the fan blades; the gas turbulators customized according to a size space of a crossbeam are mounted on the crossbeam in the cooling tower to improve the balance between a wind resistance and wind power in the tower; a water distribution system of the cooling tower adopts a water distribution manner of the inner rotary type upper spraying nozzles, such that heat exchange time of steam can be increased, the heat exchange of part of padding of the cooling can be replaced, a height of the padding can be effectively reduced, and the wind resistance of the padding is reduced. Compared with prior art, the device has the advantages that 1) an air volume can be increased by the fan with the same diameter and power; 2) the wind resistance in the cooling tower is reduced; and 3) the heat exchange time of the steam in the tower can be prolonged by an upper spraying technology, and the height of the padding can be reduced.

Description

technical field [0001] The invention relates to the technical field of cooling towers, and in particular is based on a device capable of improving the thermal performance of cooling towers. Background technique [0002] Cooling towers use the heat and mass transfer process between air and water to take away waste heat from industrial or air-conditioning systems and become an important part of the air-conditioning system. A cooling tower in which hot water uses coils and cold air to dissipate heat through heat transfer is called a dry cooling tower; a cooling tower that directly sprays hot water on the filler and allows the air and water droplets to directly contact and dissipate heat is called a wet cooling tower. The dry cooling tower can eliminate the loss of circulating water, but the cooling efficiency is low, and the cooling limit is the air dry bulb temperature; the wet cooling tower has high cooling efficiency, the cooling limit is the air wet bulb temperature, and th...
