Hyperbolic cooling tower muffler system

Abstract

Provided is a hyperbolic cooling tower noise-attenuating system comprising a decorative sound absorption module (1), a lighting observation module (2), an installation support structure (3), a modular installation fastening structure (4), and a maintenance channel (5). The decorative sound absorption module (1) has uniform specifications, and comprises a steel framework (11), an interior sound absorption face, an exterior sound insulation decorative face, elastic vibration isolation tape (12), and an upper mounting eyebolt (13). The lighting observation module (2) comprises a steel structure framework (21), an interior vibration isolating mounting member (22), a sound insulating glass panel (23), and an exterior vibration isolating positioning member (24). Further, the external specifications and configuration of the lighting observation module (2) are consistent with those of the decorative sound absorption module (1); the mounting support structure (3) is composed of a load-bearing steel structure (31), a concrete base (32), and a waterproof wall (33); and the modular installation fastening structure (4) is composed of a groove-shaped steel section (41) at the bottom of the decorative sound absorption module (1), an L-shaped steel section (43) of an adjustable fastener (42) at the top of the decorative sound absorption module (1), and a supporting steel section (44) supporting the middle part of the decorative sound absorption module (1). The groove-shaped steel section (41) is installed with a fastening bolt (45) on its inner side, and is provided with a drainage hole (46) at the bottom.

Description

technical field [0001] The invention relates to the technical field of noise control, in particular to a hyperbolic cooling tower noise elimination system capable of eliminating the noise air transmission of a large hyperbolic natural ventilation counterflow wet cooling tower. Background technique [0002] The hyperbolic natural ventilation wet counterflow cooling tower is a type of cooling tower currently used in power plants. The noise of the natural ventilation counterflow wet cooling tower is medium-high frequency, high-intensity, and steady-state noise, which comes from the high-density falling water in the tower that is equivalent to dozens of times the intensity of the rainstorm. A large continuous direct impact on the pool water. Due to its huge sound source, strong sound power level, wide frequency band, and long propagation distance, the influence range reaches hundreds of meters. In power plants, the water splashing noise of natural draft counterflow wet cooling ...

AI Technical Summary

Problems solved by technology

The higher the sound insulation barrier, the better the shielding effect, the farther the distance between the sound insulation barrier and the air inlet of the cooling tower, the more diffracted sound waves, the worse the shielding effect

At the same time, the higher the sound insulation barrier, the higher the requirements for the wind pressure resistance of the sound insulation barrier structure, and the higher the project cost.
