You may be an engineer that’s tasked with purchasing a vent silencer. There’s a lot you need to think about here. Because of this, things can seem overwhelming at times. It doesn’t have to be like this though. What we’re going to do is talk about the details you must consider. In the end, you should be able to select a suitable product without much difficulty.

How much noise?

The main area you have to look into here is the noise created by the high-pressure discharge vent. For years, researchers have contributed to calculating the noises that come from the high-pressure venting of gases. As a result they have been able to identify key factors they can use to predict the sounds. Below, you can find several examples of these details.

The factors

Firstly you need to look at the mass flow. The greater this is, the more noise the system will generate.
The molecular weight and type of gas is important as well. If your gas is relatively light, the noise will be louder.
Speaking of light gases, high temperatures lead to lighter gas flows. Consequently, everything becomes noisier.
There’s also the matter of upstream pressure vs. downstream pressure. The more excessive the former is relative to the latter, the louder the noises.
At Ventx, we go to great lengths to ensure your silencer performs to acceptable standards. We will start by looking at your unique requirements. Afterwards, we’ll use what we’ve learned to create your product.
If you have a noisy discharge vent to deal with we can be of assistance to you. Please get in touch with us to discuss your needs and find a reliable solution.

Vent and blow down silencer designs are comparable

Depending on your profession, you may need to work in a noisy environment. This isn’t an ideal situation to be in. The longer you’re exposed to loud sounds, the more likely it is that you’ll suffer negative effects such as hearing damage. Our company happens to have the perfect solution. This comes in the form of a bespoke blow down silencer. You can use one to keep noises to a minimum.
Noise is what we use to describe those sounds that we don’t want to hear. One of the largest contributors of unwanted sounds is the lack of suitable maintenance. Equipment that you don’t look after becomes ineffective in time. As part of this it could get very noisy. You need to find the perfect solution if this issue arises.
Two of the most important noise management tools out there are the blow down and vent silencers. You’ll want to make certain that you maintain them properly. That way they will work effectively and make workspaces safer.

Terms

We use the terms blow down and vent silencer when referring to the relative application we use them for. The design is comparable for both. This is because we refer to vent silencers when we’re venting at a continual run speed for a set amount of time.
There will be points when the vents are blowing down a limited volume of gas. During these instances, we refer to them as blow down. The gas starts at a high pressure but ends at a lower one when enough time passes.
We size vent silencers for sustained flow. For blow down, the sizing focuses on maximum flow.
At Ventx, we use a combination of experience and quality materials to deliver top calibre merchandise. We serve customers in the UK and abroad. In fact, we distribute almost half of our silencers to clients outside the country. That shows just how excellent they are.

All About Our Silencers

We often hear a lot about industry’s impact on the environment in reference to lowering our carbon footprint. What is not always given as much attention is the issue of noise pollution. For this problem, at Ventx we have the perfect solution with our industrial silencer design. Particularly considering noise levels in the petro-chemical and service industries, the best way to deal with this issue is through a custom design for individual applications.
Innovative Technology
By using advanced computer software, we are able to craft predictive acoustic models within the design phase, so that silencers can be designed prior to the building of the infrastructure. On the other hand, we can also work with existing machinery in order to plan the necessary measures for noise reduction. Typically, we are able to produce gas ejector silencers, direct line silences, vent discharge silencers, and control valve silencers.
Gas Ejector Silencers
A gas ejector silencer uses either hydrocarbon gas or steam, which can be both vented into the atmosphere or in a closed system in order to reduce any noise being produced. This works by attenuating air-born sound waves circulated in a flowing medium. We calculate the ejector noise and flow mixture in order the determine your specific requirements.
Direct Line Silencers
A direct line silencer differs in that it uses absorption rather than pressure variation to reduce any noise created by machinery. Often used with compressors, they can be offered as a complete unit. Alternatively, an acoustic core can be supplied, which would be inserted into existing pipe work.
Vent Discharge and Control Valve Silencers
Finally, vent discharge and control valve silencers are able to lessen the pressure of the gas flow at the same time as absorbing as much sound as possible. This method makes use of both an expansion camber, and an absorptive core. A vent discharge silencer is design to attenuate the noise level to a required sound pressure level, considering the distance from the silencer. They can be used in high pressure vents, steam vents, safety relief valve outlets, system blow downs, purge outlets and so on.
Bespoke Service
At Ventx, we are able to analyse your plans, or assess your current installation by surveying your company. The results will enable us to design and manufacture silencers especially for you, providing a bespoke service that is guaranteed to meet your needs. We use the highest quality materials along with the latest manufacturing techniques in order to craft a silencer that is perfectly suited to your business.

Silencers

Reducing the pollution resulting from production processes is an issue in all the heavy industries, and since the pollution takes different forms, so must the measures to reduce it.
Solid waste is usually stored on site until it can be removed by a suitable vehicle.  Special care must be taken when removing hazardous waste, and suitable transport arrangements must be made.  This can mean anything from having the waste containers and the vehicle which transports them correctly labelled with GHS signage, to using a vehicle specifically modified for the task (as in the case of nuclear flasks).  Liquid waste may be similarly removed, or treated on-site and discharged as effluent.
Gaseous waste can be difficult to deal with; storage of waste gas is rarely practical, as it would have to be kept in airtight containers, and with volatile compounds compression may not be an option.  Usually, the only practical solution is to neutralise the gas and release it to the atmosphere.  As you would expect, this practice is very strictly regulated.  Unwanted noise is another form of pollution, and is often a by-product of such gas treatment systems.
If the management of an industrial facility do not take reasonable measures to control the noise pollution produced by its gas venting systems they may leave the company open to prosecution under environmental law.  This is achieved by the use of an acoustic silencer (also known as a muffler) as a part of the gas discharge apparatus.  An industrial silencer works on the same principles as the exhaust silencer fitted to your car.  A system of insulating blocks and acoustic chambers modify the flow of gas to reduce the noise produced as it is released.
Ventx are specialists in the design, manufacture and installation of such industrial acoustic silencer systems.  We use advanced computer software to model the acoustic properties of an existing or planned gas discharge system and predict the characteristics of the sound it will produce.  An effective silencer can then be manufactured accordingly.  Types of silencer include:
 

  • A direct in-line silencer is the simplest type of industrial noise-abatement device. Industrial compressors are sensitive to pressure variances within the system, so an attached silencer must be designed to maintain the pressure in the pipe.  Therefore, an inline silencer achieves sound modification by use of absorptive baffles.  Different densities of material are available depending on the acoustic profile of the system.  It is usually quite simple to retro-fit an inline silencer into existing pipework.
  • An atmospheric vent discharge industrial silencer uses a diffuser and expansion chamber in conjunction with absorptive material. This reduces the pressure of the gas flow, and therefore the energy which creates the noise.
  • A gas ejector silencer is for use with a steam or combustion exhaust system.
