Exhaust gas particles filtering and eliminating device for e.g. heat engine, has concentrator with central outlet allowing lightest part of gas to pass through it and annular outlet allowing heaviest part of gas to pass through it

摘要

The device has a particle filter (2) presented in the form of an axial cylinder. A set of centrifugal concentrators (3) is circumferentially distributed around the filter and connected to the filter. The concentrators are placed parallel to each other and receive an exhaust gas flow to be processed. Each concentrator has a central outlet (5) and an annular outlet (6), where the outlet (5) allows the lightest part of the gas to pass through it. The outlet (6) allows the heaviest part of the gas to pass through it. A plate has a central passage in which the filter is placed.
