Air Blast Blowdown Silencer System for Blast Pot

摘要

A conditioning device complements a silencer with higher sound attenuation and also allows the silencer to better withstand abrasion of grit entrained exhaust air flow from decompressing an airblast pot. The device is configured to achieve four functions. First is to control and direct the exhaust air flow. Second is to absorb the impact of the entrained particles. Third is to diffuse and slow down the exhaust air velocity. Fourth is to direct and deflect the sound waves to the sound absorption surfaces located downstream.

主权项

1. A silencer for the exhaust release system of a blast pot, the silencer adapted to be placed intermediately of the exhaust outlet and a muffler, the silencer comprising:
a. A baffle positioned in communication with the exhaust outlet and through which all of the exhaust flow passes from the exhaust outlet and into the muffler; b. A receptacle placed in the center of the ring; c. A disposable wear element held in the receptacle and adapted to intercept a major portion of the debris and media which may be contained in the exhaust flow.
