Vent Silencer

Vent Silencer @ Blow Off Silencer

ISTIQ VENT SILENCER reduce the noise produced by the expansion of gas or steam from elevated pressures to atmospheric pressure. These absorptive silencers are used to suppress noise generated by high velocity gas streams such as steam vents, safety relief valve outlets, system blow downs and purge outlets. Each vent silencer is designed to attenuate the noise level to the required sound pressure level criteria at a given distance from the silencer.
Model IVS - Acoustic Diffuser & Expansion Attenuation - 30 dB

Applications

VENT SILENCER effectively silence high-velocity air, steam, and gas vents and blowdowns to atmosphere where
sonic or critical conditions exist in the valve or pipes. Typical applications include:
  • steam boiler relief valves
  • superheater header relief valves
  • boiler startup and purge
  • high-pressure air vents
  • natural gas blowdowns
  • switch valves
  • compressor blowoffs
  • autoclaves
  • steam ejectors
  • pressure valve
  • Steam turbine silencer

Construction

Typical VENT SILENCER are welded heavy-duty units. The inlet nozzle and diffuser are constructed of steel and are welded. The diffuser provides controlled pressure expansion to atmosphere and uniform flow distribution through the acoustic section of the silencer. The lined inlet plenum (expansion chamber) of the silencer is designed with a double shell separated by a layer of acoustic insulation and sound-deadening material. The inner shell is solid to prevent shell radiated noise and migration of the acoustic fill. The transmission loss across the plenum and bottom head is comparable to the silencer attenuation.

Selection Guidelines

Use the following design information from the valve data sheet for system analysis and silencer selection:
  1. Type of gas
  2. Molecular weight or specific gravity
  3. Ratio of specific heats
  4. Flow rate (lb/hr, ACFM or SCFM)
  5. Pressure and temperature upstream of valve and silencer
  6. Maximum allowable pressure drop (PSI) for valve and silencer
  7. Manufacturer’s name, and valve type and size
  8. Unsilenced noise levels from valve (if available)
  9. Silenced noise level (required at desired distance from source)
  10. Silencer inlet size and pressure rating
  11. Inlet orientation, axial or side
  12. Silencer orientation, vertical or horizontal
  13. Piping arrangement, including schematic if available
  14. Other required options

Acoustic Enclosure

Acoustic Enclosure

ISTIQ Acoustic Enclosure are available in modular forms and they come in various designs such as frame less, welded and bolted concepts. The panels are pre-fabricated which make the installation at site fast and easy.
The enclosure are provided with hinged doors, windows, ventilation systems and any other features which may be specified. The panels can be installed and disassembled as required to accommodate future changes in plant layout.

Applications

ISTIQ Acoustic enclosure are one of the most effective means for containment of excessive noise and for isolation of workers from the noise. Even where silencers are used, these can treat only the air-borne noise. The treatment of mechanical noise from the blower, motor etc. is beyond the scope of the silencer. Thus, in order to achieve low noise levels that are often specified, noise enclosures are required.
ISTIQ Acoustic Enclosure are individually designed to give the required noise attenuation and ease of accessibility. A well designed enclosure can help reduce the noise created to acceptable limits.
Typical application are on Press Machines, Compressors, Pumps, Generator Sets, Control Rooms and Sound Measuring Rooms.

Selection Guidelines

When designing an enclosure as acoustic treatment system, there are a number of factors that should be considered to maximize the design in terms of performance and cost. A few of the items that should be taken into consideration include:
  • Acoustic Environment into which machine need to be enclosed
  • Noise level to be achieved i.e. - at 1 or 3 metre away
  • Heat rejection of the equipment to be enclosed
  • Maintenance accessibility requirement
  • Numbers and size for observation windows Ventilation requirement and arrangement within the room
  • Lighting and power points
  • Overall Dimension of the enclosure
  • Consideration on the aesthetic look

Construction

ISTIQ ACOUSTIC ENCLOSURE are made of from metal sheet and perforated sheet. In between, acoustic infill (rockwool or fibre glass) is used to absorb noise. The thickness of these panels are available in 50mm, 100mm and 150mm. Different acoustic infill and different thickness of metal sheet are used depending on the application to ensure excellent performance and cost effectiveness without sacrificing quality.
