Regarding pipeline pressure relief (gas) silencing
Thread Content
Question: The existing compressor supplies compressed air at 0.6 MPa, with a storage tank for buffering at the compressor outlet. The main issue is that the compressor generates too much gas; the storage tank has only an on-site vent port (DN50), and excessive noise is produced when the manual valve is opened. Problem to solve: Eliminate venting noise, come up with solutions. The silencer cannot be purchased right away at the moment, but the noise problem needs to be addressed. My plan is to use a DN50 seamless steel pipe with 200 holes of diameter φ5 drilled in it (which corresponds to twice the cross-sectional area of a DN50 pipe) in order to achieve noise reduction ； Use a flame arrester as a temporary silencer ； Use the compressor air filter (outer diameter 500, inner diameter 400), seal both ends of it, and leave one end with a DN50 flange to serve as a silencer. I hope fellow sailors can help by offering suggestions. Urgent! Urgent! Urgent! ! !
In case of an emergency, connect a pipe section to lead it into the pit,,,,,
It actually doesn’t need to be that complicated: you can add a large diameter reduction at the exhaust pipe to slow down the flow rate of gas as it enters the atmosphere, and then install a jacket at that diameter reduction point, filling it with insulation material. This will help to significantly reduce noise levels at the site.
If the vent pipe itself is relatively small and then its diameter is increased further, the sound of throttling should be quite loud as well
On the fourth floor? That’s quite far, haha
In fact, the source of the greatest noise is still at the nozzle, that is, at the end of the tube
Yeah, the flow rate at the outlet is too high to handle
Don’t act blindly if you don’t know something, haha. I merely offered a possibly viable reference.
