Buffer diffusion emptying silencer

The utility model discloses a buffer diffusion emptying silencer, which comprises a barrel. One end of the barrel is arranged in a connecting tube; the connecting tube is connected with an exhaust emptying conduit; a connector is arranged at one end of the barrel extended out of the connecting tube; a seal cover is arranged at one end of the barrel positioned in the connecting tube; and the side wall of the barrel positioned in the connecting tube is provided with a plurality of air outlets. The buffer diffusion emptying silencer has the advantages of: high-pressure air after an anti-surge valve is opened is exhausted and emptied by the buffer diffusion emptying silencer, the exhaust of the high-pressure air is smooth, and the airflow is stable, so the impact of the emptied air on the anti-surge valve and the exhaust emptying conduit is greatly reduced and the service life of the anti-surge valve is prolonged; the discharged noise can be greatly reduced, and the controlled noise is reduced to below 90dB (A) from the primary 120dB (A) through practical test; and the buffer diffusion emptying silencer has compact and reasonable structure, easy production, low manufacturing cost and the like.
