Abstract

The invention discloses an efficient and environment-friendly mechanical draft cooling tower. The efficient and environment-friendly mechanical draft cooling tower comprises a tower body and a noise reduction structure, wherein the noise reduction structure comprises an air exhaust muffler at the top of the tower body and an air intake muffler at the bottom of the tower body; the mechanical draftcooling tower also comprises a sound insulation deflector arranged below the air exhaust muffler, a noise reduction demister arranged below the sound insulation deflector, a water collector arranged below the noise reduction demister, a water distribution packing area below the water collector and a falling water silencing device arranged below the water distribution packing area. The efficient and environment-friendly mechanical draft cooling tower can reduce the generation of mist and eliminate low-frequency noise generated by fan blades.

Description

technical field [0001] The invention relates to an efficient and environment-friendly mechanical ventilation cooling tower, which belongs to the field of cooling towers. Background technique [0002] Existing mechanical ventilation cooling towers spray hot water onto the surface of the filler and contact the cold air through the filler, and an exchange occurs between the hot water and the cold air, and part of the hot water is evaporated, that is, the latent heat of evaporation in the evaporated water vapor is released into the air. In winter or when the ambient humidity is high, a large amount of plume will be generated after the saturated hot and humid air dissipated by the mechanical ventilation cooling tower contacts the atmosphere, which will affect the environment and nearby traffic. Traditional mechanical draft cooling towers have the difficulty of eliminating low-frequency noise. Therefore, it is necessary to study a high-efficiency and environmentally friendly mec...
