DEVICE FOR TREATING EXHAUST GAS CONTAINING SOOT PARTICLES

摘要

The invention relates to a device (1) for treating exhaust gas containing soot particles (2), which device at least comprises at least one ionisation element (3) for ionising soot particles (2), at least one filter element (4), wherein an electric potential can be applied to at least a section of the filter element (4), and at least one agglomeration unit (8) for at the least partial agglomeration of electrically charged soot particles (2). The agglomeration unit (8) is disposed between the ionisation element (3) and the filter element (4), wherein the agglomeration unit (8) has at least one outer pipe (9) and at least one inner element (10). By means of the invention, the filtering power of an exhaust system of an internal combustion engine is increased by an increase in the agglomeration rate of the soot particles.
