Howdy,
I am working on a gas system that operates at about 500 psig with N2. We have a relief valve, a bleed valve and an electronic regulator with exhaust outlets that tie in to an exhaust line.
On the end of the exhaust line I want to put a silencer or muffler, but the pressure is too high for any standard-service silencer I know of or have seen in my research and it is not nearly important enough to warrant the heavy industrial exhaust mufflers used in big plants. SO I threw together a design and I figure I'll post it up here to get some input.
It is a series of concentric tubes. I figure the high pressure gas will have room to expand and lose velocity and pressure as it flows through larger spaces, and I have some hard foam inserts in there (the dark khaki stuff) to take some energy out of the pressure wave. Probably not very good for continuous-operation processes, but for the intermittent pressure-relief I think it would do a lot to make dumping some pressure less aurally unpleasant. And it looks like it will cost about $75.
Am I way off or what?
