In-line silencers use the same principle of acoustic design as a vent silencer. When it comes to in-line noise, you have to consider reducing the vibration caused by the valve noise. The reason for this is that noise is basically air born vibration.
There are two types of silencer for in-line applications;
- Control Valve Silencers use a design to provide a pressure drop or back pressure. They primarily see use in conjunction with a control valve. A combination of diffuser design and an absorptive section achieves the attenuation.
- Direct In-Line Silencers use a design to produce as little pressure loss as possible. But, they achieve the required attenuation using only an absorptive section.
Ventx can manufacture both types of In-Line silencer. These are for use in pressurized systems and to a suitable pressure design code. There are many variations with In-Line silencers. We can design and supply just Diffuser Silencers or Insert Silencers. We do these to suit your individual application and needs.
At Ventx, we design silencers to provide a required back pressure. This can help when selecting a valve. All design work and manufacturing for silencer inlets is done with reference to a design code.
Noise attenuation measures often focus on noise from exhaust and venting devices. This is the case in a lot of any industrial processes. But, much of the noise pollution can be at an intermediate stage. This includes those which occur as a result of power generation and other processes. If nothing deals with these, the noise levels can have an adverse effect. This is something both staff and visitors can experience. They may be exposed to them repeatedly and for extended periods. There are specific designs of silencers for exhausts and venting devices. Also, there are in-line silencers which are made to deal with noise that is as a result of gas flow within ducting or other conduits.
Whenever a flow of gas passes through a chamber or junction, there is the potential for flow disruption. This is also the case just when it goes from one diameter of pipe to another. This results in unwanted noise. This noise is sometimes amplified by the downstream piping. Fitting an in line silencer at such a point in the system balances the flow. This will end such noise at the source.
Where to turn for help with industrial noise
At Ventx, we custom build each direct in-line silencer we supply. We do this to provide optimal performance in a specific system. We begin with an acoustic analysis of the system. This involves recording the levels and frequencies of noise produced. It might be that your facility is still under construction, or has not yet left the drawing board. If so, we can use your specifications along with our sophisticated computer software. We can then model the acoustic properties of the proposed installation.
After arriving at a design, manufacturing for your direct in-line silencer begins. This takes place using long strand fibreglass acoustic packing as absorption material. This acoustic core can be supplied in a custom fabricated in line silencer housing. Or, there is the option of as-is so that you can insert it into your existing pipework. A good acoustic match will mean acoustic cladding of pipework is unnecessary.
