ABSTRACT:
The invention relates to a device and a method for the aftertreatment of exhaust gases from combustion engines, in particular from internal combustion engines. The device according to the invention and the method are intended to be of simple construction, should be inexpensive to produce and operate and should have less adverse effect on the flow conditions in the exhaust gas stream. To achieve this object, at least one region which is filled with beads is provided in the exhaust-gas stream, the beads preferably being hollow beads. The exhaust gas from the combustion engine is passed through this region, and it is possible to achieve particle agglomeration with simultaneous separation of these particles. In addition, further regions which are filled with metal fibers may follow the at least one region filled with beads, and the exhaust gas is additionally passed through these further regions.
