一种防尘、耐高温消声器的研究

A dust-proof and heat-resistant silencer

一种新型的消声器能应用在高温、含尘的条件下。消声器设计采用了四分之一波长吸声，其内部消声构造与防尘、耐高温有机结合起来．实现了防尘和消声的较佳效果．

A new kind of silencer used in conditions where there is heat and dust. The silencer is based on the principle of one-quarter wavelength maximum sound absorption. The interior structure of the silencer is designed to combine the noise elimination with the dust-proof and heat-resistance and creates satisfactory result of dust-proof and noise elimination.
