Tubular device for the separation and combustion of soot particles in exhaust gas streams, in particular diesel soot, and method for removing soot particles in exhaust gas streams, in particular diesel exhaust gases

摘要

It is u. a. A tubular device for the separation and combustion of soot particles in exhaust gas streams, in particular diesel soot, is provided with a catalyst and a filter, which is characterized in that the soot ignition point temperature-reducing catalyst is applied as a coating on a first filter (1), a second filter ( 2) at least partially encloses the first filter (1) in the longitudinal direction and / or radially, so that exhaust gas containing soot particles is passed through the first filter (1), the soot particles being separated on the first filter (1) and on the second filter (2) and at the same time the exhaust gas is conditioned on the first filter (1) for burning the soot particles separated on the first and second filters (1, 2).
