Silencers for nitrogen, oxygen, carbon-di-oxide, hydrogen rich gases and other process gases can be supplied for both online pressure silencer as well as vent silencers. The prime requirement for a vent silencer is its ability to handle with total reliability the rapid release of large quantities of steam from high pressure to atmosphere and attenuating high levels of noise generated at the vent for steam at wide range of pressure and temperature conditions. The silencers are made out of concentric annular acoustic cylinders enclosed with a robust steel casing with dished end or flat end at one end.
The fluid enters through the diffuser and passes through the annular space between the acoustic packing where the sound energy is absorbed. The straight flow path through the annular acoustic cylinders ensure minimum pressure drop. A weather cowl for rain protection is available as an optional item. The material of construction offered shall be suitable for the process gas application.
Product Description :
Gas Vent Silencer is used for reduce the noise from the valve system . Generate the noise will be created in high decibel frequency.It may be occur in condition of supersonic. So in this type of unwanted noise should be arrest , for this noise arrest using the devise is Vent Silencer into atmosphere in sonic level. In this type of silencers used in oil & gas industries , Heat recovery systems , boilers ,chemical industries.,etc.,We designed the silencer based on your requirement data’s flow rate, pressure, temperature.
Our expects engineers choose for single stage diffuser or Multi stage diffuser pipe based on your data’s.
Working Principles :
From the fluid steam enters into the silencer . Fluid occurs may be in high flow passes into the silencer . Here velocity and sound attenuation is very high , so step by step should be decrease the velocity by using diffuser pipe . Diffuser pipe will be connect to the process flow pipe line. In diffuser pipe, bores or holes created on the surface area . It will be help to reduce the fluid velocity and fluid it entering into the internal chamber. In internal filled by acoustic materials. Fluid passes through the acoustic materials into the atmosphere or discharge area .
