Title:
熱音響消音器
Document Type and Number:
Japanese Patent JP7422402
Kind Code:
B2
Abstract:
To provide a thermoacoustic noise eliminator capable of generating high noise elimination effect although preventing pressure loss generated by a noise elimination part.SOLUTION: A thermoacoustic noise eliminator 1 comprises a flow passage R to which a vibration flow of working gas is input from an upstream R1 side and which is open on a downstream R2 side, and a heat accumulator 2 which is provided in the flow passage and held in a humid state with liquid, and consists of a thermoacoustic device. The heat accumulator has a temperature gradient from the upstream side to the downstream side, and attenuates acoustic power of the working gas.SELECTED DRAWING: Figure 1
