Description

Technical Field

[0001] The invention relates to an N-type continuous folding water-falling silencer, belonging to the technical field of noise control. Background Art

[0002] Cooling towers are widely used cooling equipment in industrial enterprises. They are also one of the main noise sources of industrial enterprises, and have a great impact on the surrounding environment. Water splashing noise is the main source of cooling tower noise. Existing cooling towers, especially cooling towers used in power plants, have high water drop strokes, and the noise problem is more prominent. As the size of cities continues to expand, residential areas are closer to factory areas, and some of these factory areas are even located in densely populated areas. High-noise cooling towers will seriously affect the health and lives of surrounding residents and workers.

[0003] In order to ensure that the noise level at the factory boundary and surrounding sensitive points meets the standards, it is necessary to use a large number of noise reduction measures such as ventilation silencers and sound insulation barriers on the existing cooling towers. This has high construction costs, large flow resistance, and will also affect the cooling effect.

[0004] Existing sound-absorbing pads are generally honeycomb structures made of engineering plastics, and their structure is similar to certain types of fillers. They are low in cost and low in noise reduction, generally about 5dB. At the same time, since the sound-absorbing pads are subjected to continuous high-intensity impact of falling water, they are prone to aging and cracking; existing falling water noise devices often use plastic fillers, sponges, high-mesh screens, etc. as the main structural devices, but these devices either have a large response sound after the structure itself is impacted (such as plastic fillers), or the surface of the structure quickly forms a water film when the falling water flow is slightly large, resulting in a significant increase in the sound radiation efficiency of the sound-absorbing structure (such as sponges, screens, etc.), so the noise reduction effect is generally limited.
