Silencer-separator device

摘要

A silencer-separator having a cylindrical casing of circular cross section which is divided into an upper separator chamber and a lower expansion chamber. An inlet pipe directs a gas stream into the expansion chamber, and a pair of angularly disposed tubes direct the gas upward through a divider into the separator chamber with a swirling motion along the interior wall surface. A tubular central outlet extends through the upper end closure and has an entrance a substantial vertical distance therebelow. A peripheral baffle adjacent the interior wall collects entrained particles in the separator section and the collected particles are drained through a tube that may lead to the bottom of the expansion chamber. A perforated cylindrical body filled with a noise-attenuating fibrous substance is coaxially supported within the central outlet.
