Abstract
A dust collector for removing particles entrained and transported in a flow of transport air which comprises a housing having a generally cylindrical chamber with a tangential inlet for introducing the transport air and causing it to assume a helical flow path within the chamber. A plurality of vertically extending cylindrical filter elements are disposed within the chamber, and conventional reverse pulse-jets are provided for periodically cleaning the filter elements by creating a reverse flow of air outwardly therethrough. A wall arrangements is provided adjacent each filter element to create a flow channel that directs the outward flow cleaning air and particles removed from the filter elements thereby in a direction toward the main helical flow path of the transport air to substantially reduce re-entrainment of the removed particles.
