The invention discloses a silencer device for eliminating disperse high-frequency whistlers. The device comprises an airflow pipe and a sound silencing pipe, the sound silencing pipe comprises a supporting unit and an air permeable medium arranged on the outer surface of the supporting unit, the supporting unit is of a hollow structure, external airflow enters the airflow pipe through the air permeable medium, the characteristic impedance of an air inlet of the airflow pipe is not coincident with the characteristic impedance of an air outlet of the airflow pipe, a layer of air permeable medium is arranged on the end face of the air inlet, and a flow guide unit is arranged on the air outlet. The silencer device can effectively suppress and eliminate generation of medium and high frequency disperse noise, can effectively filter pollutants such as dust and metal particles and has two effects on noise reduction and filtering; and the design scheme that a replaceable component is adopted at a key part, influencing vacuum pipe recompression system noise characteristics, of a silencer is adopted, and the medium and high frequency disperse noise with the different frequency characteristics can be effectively suppressed.
