<p>In a dust filter with a compressed gas back-purging device in which a number of suspended filter elements, in the form of tubes or chambers and acted on externally by the dust-laden gases, are collected into groups of separated pure gas channels, extending through the partition wall between crude and pure gas space and open at the end into the pure gas spaced as well as acting, in conjunction with valve-controlled compressed gas nozzle situated in front of the opening as a jet blower, the improvement whereby the pure gas collecting channels are divided in the plane of the partition wall, and their pure gas sections passing through this wall are connected rigidly there to, while their crude gas sections formed by the housing the cross section of which increase in the direction of discharge of the purer gases, are individually releasable with the filter elements installed on the housing and are removable from the filter upwardly.</p> |
