| description | The utility model discloses a conical pipeline silencer. The device is mounted above a pipeline and comprises a straight pipe section (1), the diameter of the straight pipe section (1) is the same as that of a pipeline, the upper portion of the straight pipe section (1) is a horn mouth pipe section (2), and the pipe wall of the straight pipe section (1) and the pipe wall of the horn mouth pipe section (2) are narrow cavities. A micropore plate silencing body (3) is arranged in the middle of the horn mouth pipe section (2), the micropore plate silencing body (3) is an inverted-cone-shaped cavity, and a micropore plate (4) is arranged on the face, corresponding to the horn mouth pipe section (2), of the cavity. According to the utility model, the noise reduction effect is improved by utilizing the principle that the wedge is an efficient sound absorption structure because the noise elimination body of the microporous plate is the inverted conical cavity.
