Silencer-separator device

A silencer-separator device comprising:

• a generally cylindrical casing which is generally circular in cross section;
• means intermediate the ends of said casing dividing it into an upper separator chamber and a lower expansion chamber;
• means closing the bottom of said expansion chamber;
• an inlet pipe communicating with said expansion chamber for directing a gas stream thereinto;
• at least two flow tubes defining at least two passages through said dividing means, said flow tube means being disposed at an angle between about 30.degree. and about 60.degree. to the vertical and being located to direct the gas upward into said separator chamber with a swirling movement along the interior wall surface of said casing;
• means closing the upper end of said separator chamber;
• central outlet means which extends downward through said upper closure means and which is located generally along the axis of said casing, said outlet means being generally tubular in shape and having an entrance located a substantial vertical distance below said upper closure means;
• peripheral baffle means adjacent said interior wall surface of said separator which collects particles entrained in the gas stream;
• and,
• means disposed vertically below said peripheral baffle means for removing the collected particles from said upper chamber.
