Vent Silencer Design

A vent silencer is a device used to reduce unwanted noise created by gas or steam flow in a pipeline discharging directly into the atmosphere. This noise can be generated due to the high velocity flow through the valve and turbulence created around any obstacle in the line that suddenly restricts or changes the direction of flow such as valve or an orifice device.

Vent silencers find wide applications in high pressure vents, steam vents, safety relief valve outlets, system blow downs, purge and flare outlets. The generated noise is a function of upstream pressure and temperature, type of gas, the valve size and type, plus the effect of down stream piping.

Ventx design each silencer to attenuate the noise level to the required sound pressure level specified by the customer. Read more about Vent Silencer Design.

Power generation, waste treatment, manufacturing, and many other industries employ processes which involve the transfer of gas under pressure.  And whether this gas is air, steam, or some other chemical, it must at some point leave the system and be vented to the atmosphere.  Since the release of pressurised gas is by its nature very noisy, a good vent silencer design is critical in reducing the noise levels produced by the process to keep it in line with relevant legislation.  If an industrial silencer is poorly designed, it may fail to provide sufficient attenuation resulting in inadequate sound damping, or it may modify the sound inefficiently resulting in unnecessary expenditure and poor performance of the equipment.

Ventx are specialists in industrial silencer design.  In fact, we are one of the leading silencer design companies in the UK, as a glance at our client list will show.  Some system designers misunderstand industrial silencers, believing them to be little more than metal pipes filled with industrial waste.  The fact is, silencer design is a highly scientific process, and we apply cutting edge scientific methods to design our products.

The Ventx design procedure begins with the customer.  Your process data can provide us with crucial information when designing a vent silencer to match your needs perfectly.  In the absence of such data, we can survey your facilities and take measurements to build up an accurate picture of the by-products which result.  We then use advance computer software to model the acoustic properties of the system as it stands, from which we can arrive at an appropriate exhaust silencer design.

Is your manufacturing or treatment process still at the design stage?  Or maybe you are upgrading?  Our specialists can anticipate your needs, so get in touch with our design team today.
