<p>A process is described for cleaning in each case part of a plurality of filter elements arranged in a filter chamber (1 to 6), which are used for removing the dust from a pressurized dust-laden gas using scavenging gas supplied in the opposite direction to the normal flow direction. The scavenging gas flows from the clean gas side through the filter elements from which the collected dust is to be removed. The scavenging gas is branched from the pressurized clean gas flow removed from the filter elements not subject to the cleaning process. The scavenging gas from the particular filter chamber is supplied to the dust-laden gas side. The mixing of the scavenging gas with the dust-laden gas takes place with the aid of a compressed gas jet pump (8), which also exerts a suction action on the scavenging gas.</p> |
