Problems solved by technology

[0003] In order to ensure that the noise of the factory boundary and surrounding sensitive points meets the standard, it is necessary to adopt a large number of noise reduction measures such as intake and exhaust mufflers and sound insulation barriers for the existing mechanical ventilation cooling towers. The construction cost is high, the flow resistance is large, and the cooling effect will also be affected.

Abstract

The invention discloses a low-noise mechanical ventilation cooling tower which comprises a cooling tower body, a water supply and distribution system, an electronic element assembly and a water falling silencing device are arranged in an inner cavity of the cooling tower body, a fan system is arranged at the top of the cooling tower body, and a water pool is arranged at the bottom of the cooling tower body. And the water falling silencing device is arranged above the water tank. The fan system is adopted to replace an original large fan, the fan noise is reduced, meanwhile, the water falling silencing device is installed in the tower, the water spraying noise is reduced, and therefore the purposes of reducing the noise of the cooling tower and improving the energy efficiency are achieved.

Description

technical field [0001] The invention relates to a low-noise mechanical ventilation cooling tower, which belongs to the technical field of noise control. Background technique [0002] Mechanical ventilation cooling towers are cooling equipment widely used in industrial enterprises, and are also one of the main sources of noise in industrial enterprises, which have a greater impact on the surrounding environment. The noise of mechanical ventilation cooling towers mainly comes from the noise of water splashing in the lower part and the noise of exhaust air in the upper part. The noise problem of existing mechanical ventilation cooling towers, especially cooling towers for power plants, is more prominent due to the large fan and high water falling stroke. As the city continues to expand, residential areas become closer to factories, some of which are even located in densely populated areas, and high-noise cooling towers will seriously affect the health and life of surrounding re...
