Abstract
A fluid discharge silencer for steam or other vapors or gases (with or without entrained solids or liquids) has an expansion chamber into which the fluid is passed through an inlet duct which discharges the fluid over an extended region of the chamber, flow deflector means in the chamber gradually redirecting the flow of gas from the inlet duct to change the direction of flow and to permit the gas phase components of the fluid to expand; the expansion chamber has an outlet which in use is connected to a silencer such as a parallel splitter silencer for further attenuating noise in the discharge flow. The inlet duct can be an elongated pipe having a longitudinal discharge aperture arrangement discharging the fluid into a trough-like redirecting structure which removes entrained components and redirects the flow.
Claims16
An apparatus for use in a silencer system through which a gas or vapour discharge is passed, the apparatus having an expansion chamber for permitting expansion of the discharge to reduce substantially its velocity, the expansion chamber including an outlet arranged for communicating with silencing means an inlet duct elongated along an axis and having a substantially closed side wall extending around the axis of elongation of the inlet duct and an axially elongated transversely directed smooth gas discharge configuration interrupting said side wall and extending therealong in a zone constituting a minor proportion of the inlet duct wall area for introducing the discharge into the expansion chamber over an extended region of the chamber, flow deflector means shaped for gradually redirecting the flow of gas or vapour from the inlet duct through the expansion chamber and to the outlet while allowing expansion of the gas or vapour discharge, the outlet providing a gas flow direction substantially at right angles to the direction of elongation of the inlet duct.
An apparatus for use in a silencer system through which a gas or vapour discharge is passed, the apparatus having an expansion chamber for permitting expansion of the discharge to reduce substantially its velocity, the expansion chamber including an outlet arranged for communicating with silencing means, an inlet duct elongated along an axis and having a substantially closed side wall extending around the axis of elongation of the inlet duct and an axially elongated transversely directed smooth gas discharge configuration interrupting said side wall and extending therealong in a zone constituting a minor proportion of the inlet duct wall area for introducing the discharge into the expansion chamber over an extended region of the chamber, flow deflector means shaped for gradually redirecting the flow of gas or vapour from the inlet duct through the expansion chamber and to the outlet while allowing expansion of the gas or vapour discharge, the outlet providing a gas flow direction substantially at right angles to the direction of elongation of the inlet duct, the aperture arrangement being directed vertically downwardly and the deflector means comprising a curve plate structure confronting the aperture arrangement.
