Abstract
The blowdown silencing system includes an initial restrictor in communication with a blast pot vessel for controlling the flow of pressurized air from the vessel into a first expansion chamber. The outlet of the first expansion chamber is in communication with a reducer. The reducer outlet is in communication with a shut-off valve, which may be manually controlled or automatic. The shut-off valve may be upstream or downstream of the reducer. The outlet of the reducer/shut-off valve is introduced into a muffler system which includes an exhaust path and a deflector for absorbing and/or deflecting abrasive particles which may be evacuated from the blast pot vessel during blowdown.
