ABSTRACT:
An apparatus for removing soot from the exhaust gases of an internal combustion engine using a loose material filter. The object is to confine the loose material in a particularly effective manner so as to produce a very high degree of soot separation in the filter. This is achieved essentially in that the (loose material) fixing element is composed of two vertically and coaxially disposed perforated tube members that form a first annular chamber, with those surfaces of the perforated tube members that face the first annular chamber being each provided with a fine-mesh screen and adjacent thereto, a coarse mesh screen. The exhaust gas passes through the filter insert transverse to the gravitational effect of the granulate particles. To compact the granulate fill, the first annular chamber can be charged with compressed air via a second annular chamber that is adjacent thereto and is provided in the upper region of the filter housing.
