The principle of the silencer of the application is as follows:
The sound absorbing material is fixed on the inner wall of the airflow channel or arranged in the pipeline according to a certain mode to form the resistive muffler. When sound waves enter the resistive muffler, a portion of the sound energy rubs in the pores of the porous material and is converted to heat energy which dissipates, attenuating the sound waves passing through the muffler. The device has the characteristics of good silencing effect on medium and high frequency and poor silencing effect on low frequency, and is suitable for the condition of low gas flow rate.
The noise silencer can reduce the noise radiated from the silencer to the outside by the reflection and interference of the sound energy caused by the change of impedance in the sound propagation process of abrupt parts of the pipeline section or bypass resonant cavities, etc. The sound wave propagates in two pipelines with different cross sections, and is transmitted into a pipe with the cross section of S2 from a pipe with the cross section of S1, and the S2 pipe is equivalent to an acoustic load on the S1 pipe, so that reflection and transmission of partial sound waves can be caused. The method is mainly suitable for reducing noise in low frequency and middle and low frequency bands. The resistive muffler has the greatest advantages that a porous sound absorbing material is not needed, so the resistive muffler is better than the resistive muffler in the conditions of high temperature resistance, moisture resistance, high flow rate and high cleaning requirement, and is suitable for air compressors, internal combustion engines and automobile exhaust noise (the condition of high air speed).
Impedance composite noise elimination, namely, the noise elimination principle of resistance and resistance is formed by combining proper structures, and the superposition of noise elimination values of the resistance and the resistance in the same frequency band (not a simple superposition relation) can be qualitatively considered. The noise-eliminating device has the characteristics of low, medium and high frequency noise elimination performance, and is suitable for eliminating noise of blowers, large wind tunnels and test benches.
The above examples merely illustrate specific embodiments of the application, which are described in more detail and are not to be construed as limiting the scope of the application.
