Abstract

A filtering and post-combustion device for waste gases, particularly of internal combustion engines, is designed with a plurality of filtering elements which are mounted at equally spaced radial locations within a circular or oval housing and are radially transversable by the gas stream which enters and leaves axially through funnels. At the inner filtering elements, the outlet chambers are separated from the adjacent inlet chambers of the respective following filtering element by axially extending walls. Each individual filtering element comprises a perforated retaining shell, a filter body, such as a wire mesh, permeable to gas, and a perforated supporting wall.
