Abstract
A dust trap for flowing gases comprises an inlet conduit which terminates in a transverse wall for impact-type dust separation (i.e. inertial separation). A side entry port is positioned adjacent the transverse wall. The side entry port communicates with the circulation chamber defining an angled opposed wall in the opposite side of the chamber of the side entry port. The angled, opposed wall is substantially perpendicular to gas flow through the side entry port, to cause flowing gas from the side entry port to split vertically into swirling upward and downward flow patterns for further dust separation. The lower part of the circulation chamber is normally closed off from the exterior. The upper part of the circulation chamber communicates with an outlet conduit.
