Hyperbolic-curve type sound attenuating system of cooling tower

Abstract

The invention discloses a hyperbolic-curve type sound attenuating system of a cooling tower. The hyperbolic-curve type sound attenuating system consists of a decorative sound absorbing module, an observing and light-catching module, a mounting and supporting structure, a module mounting fastening structure and a maintaining channel, wherein the decorative sound absorbing module is unified in specification, and consists of a steel structure framework, an inner side sound-absorbing surface, an outer side sound-isolating decorative surface, an elastic vibration-isolating adhesive tape and a top mounting lifting ring; the observing and light-catching module consists of a steel structure framework, an inner vibration-isolating mounting component, sound-isolating glass and an outer vibration-isolating positioning component, and is consistent with the decorative sound absorbing module in appearance specification and configuration; the mounting and supporting structure consists of a bearing steel structure, a concrete pedestal and a waterproof partition wall; the module mounting fastening structure consists of channel-shaped shape steel, bottom of which is equipped with the decorative sound-absorbing module, L-shaped shape steel, and supporting shape steel, wherein the decorative sound absorbing module on the upper part is equipped with a buckle type adjustable fastening part; the middle part of the supporting shape steel supports the decorative sound-absorbing module; a fastening bolt is mounted on a position, close to the inside, of the channel-shaped shape steel; and a water leakage hole is formed in the bottom of the channel-shaped shape steel.

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.
