Noise Reduction With the Use of Vent Silencers

Introduction to Vent Silencers

A vent silencer is also known as a blow off silencer. It reduces the amount of noise produced by gas or steam flowing through a pipeline that discharges directly into the atmosphere. At a particular distance from the silencer, each vent silencer is intended to reduce noise to the appropriate sound pressure level. Vent Silencers are a mix of absorptive and reactive type silencers that are used to minimise noise caused by the expansion of steam or gas from a high pressure level to atmospheric pressure. Each Steam Vent Silencer is engineered to reduce high and low frequency noise levels to the ideal sound level standards for a certain environment. The total dimensions of a Steam Vent Silencer are related to the flow rate of the specific and desired noise reduction. The high velocity flow through the valve, as well as the turbulence caused around any impediment in the line that limits or alters the direction of flow, such as a valve or an aperture, can cause this noise.

Vent silencers are used in high-pressure vents, steam vents, safety relief valve outlets, system blow downs, and purge outputs, among other places. Upstream pressure and temperature, the kind of gas being vented, valve size and type, and the effect of downstream pipes all influence vent and blowdown noise. At a particular distance from the silencer, each vent silencer is intended to reduce noise to the appropriate sound pressure level. This is why vent and blowdown silencers are rarely available in catalogues. The information provided here can be used as a guideline.

What is the purpose of a vent silencer?

To cover a larger sound frequency range, industrial steam vent silencers use two fundamental concepts to minimise noise. Rather than pushing sound outward, vents utilise reactive components to reflect it back toward the source. The noise’s magnitude diminishes and dampens as it travels. The noise produced by the release of high-pressure steam or gas through a control, relief, or safety valve can be comparable to the launch of a big rocket. Such levels of noise are unhealthy for individuals in the immediate proximity and can be annoying to those who are further away from the source. The user is advised to consider the unsilenced noise levels used as the foundation for the noise estimates rather than only the muted levels when evaluating a vent silencer proposal. Stoddard Silencers adopts a conservative approach to safeguard the end user from having an undersized silencer installed.

A diffuser and an acoustical portion are required to mute vent noise. Stoddard Silencers offers a variety of designs to help fine-tune the required attenuation for each vent application. While there is no industry standard for measuring a vent’s unsilenced noise level, Stoddard Silencers bases its calculations on Lighthill’s energy model.

What is the purpose of a steam vent silencer?

Vent silencers are used to reduce noise caused by the expansion of gas, steam, or air to atmospheric pressure at high temperatures. Silencers used to suppress noise produced by the expansion of Gas, Steam, or Air at elevated temperatures to atmospheric pressure are referred to as vent silencers.

Introduction to Thermowrap

Thermowrap General Purpose Wrap is a bubble membrane with reflective foil surfaces on both sides that provides heat resistance comparable to 55mm polystyrene. This thermawrap insulation may be used on walls, floors, motor homes, dog kennels, rabbit hutches, caravans. The safety of operational workers in spaces or rooms holding engine components, prime movers, and industrial exhaust systems is critical to any firm. The greatest risk to personnel is heat and component temperature variations during operation, which must be mitigated and managed. Similarly, although not through physical contact, noise and vibration control are secondary elements that can help you achieve severe noise control safety regulations by improving workplace safety and environmental conditions for employees.

Thermowrap is utilised as a pressure containing repair to seal leaks and as a reinforcing repair to restore the strength of a pipe in the axial and circumferential directions in plants, refineries, tank farms, ports, and on offshore assets around the world. It’s great for repairing tees, flanges, and tubes with different diameters that have difficult geometry. Wheat grain and flax, which have a natural fresh aroma and keep heat better than artificial fillers, rice, or seeds alone, are amply stuffed in Thermo Wraps. The grains, which have been infused with essential lavender oil, help to relax the body and mind. Our goal is optimal comfort and grain distribution while resting on the neck, so we don’t scrimp on the filling. The ultimate result is a soft, supportive wrap rather than a harsh, firm one.
