Silencer pipe

Abstract

The present invention relates to a sound deadening panel section and related sound deadening ducts. The sound absorbing panel section may include sound absorbing material, a first shell surrounding the sound absorbing material, and a first coupler configured to couple the first shell to a second shell of an adjacent sound absorbing panel section. Acoustic panels may employ multiple sections that are joined together to form a single acoustic panel. The acoustic duct may include a frame forming a working fluid flow path and a plurality of acoustic panel mounts positioned within the frame, each configured to slidably receive an acoustic panel, such as those described herein.

Description

technical field [0001] The present invention relates generally to acoustic attenuation, and more particularly to silencer panels and related silencer ducts. Background technique [0002] Noise reduction systems are used on a large number of industrial machines, such as turbines, to reduce the acoustic impact on the surrounding area. In gas turbine systems, for example, noise reduction systems are applied in inlet ducts, gas turbine casings, and barrier walls. Traditionally, acoustic panels and acoustically treated walls have been employed in noisy areas in order to obtain the necessary acoustic reduction requirements. One mechanism to reduce acoustic impact is to treat the walls with sound absorbing material. Another mechanism is to place the sound-absorbing panel in the area where noise reduction is required, such as in the working fluid flow path in the intake system duct, to prevent noise leakage. [0003] With regard to sound deadening panels, each panel generally com...

Problems solved by technology

For example, the enclosure is very heavy and also difficult and expensive to manufacture due to the cost of the material and the need for welding to form the panels
