Abstract

In the filter and afterburning device for exhaust gases, especially for internal combustion engines, a plurality of layers of cylindrical filter elements of essentially circular-ring-shaped or oval-ring-shaped cross-section, through which the gas can flow radially, are arranged with equidistant radial spacing one inside the other in a housing between an inlet funnel and an outlet funnel, forming similarly shaped inlet and outlet spaces. Each filter element comprises a gas-permeable filter body made of wire mesh, ceramic fibres or a combination of the two and surrounded on both sides by a gas-permeable metallic jacket, the filter bodies being wound into a spiral using spacing elements, with a spiral inlet channel and outlet channel, each of which is closed on the opposite side, and the surrounding jackets, designed as perforated metal bands or metal mesh bands, being provided with a catalytic coating for the purpose of converting gaseous pollutants. <IMAGE>
