Permanent tube and shell filter for diesel engine exhausts - to extract dust and residues from fuel additives without coking up the filter

摘要

Filter for cleaning engine exhaust, comprises a bundle of filter tubes fixed in a shell and an end plate closing one end of at least some of the tubes which can be separated from the tube bundle. Either the end plate or the tube bundle is mounted to rotate relative to the other. The end plate contains openings which match with the end of some of the filter tubes. The rotating tube bundle turns about a central axis. USE/ADVANTAGE - Cleaning of exhaust gases from motors such as diesel engines. In particular extracting dust such as submicron carbon particles and residues from fuel additives. The device is a permanent filter for engine exhaust, which does not block up with residues from the catalytic reaction of the exhaust.
