Catalytic exhaust gas cleaning device - has expansible laminate with inner layer gap at interspace between adjacent catalyst bodies

摘要

A catalytic exhaust gas cleaning device has a housing (3) contg. two or more spaced catalyst bodies (1) accommodated by an expansible mat (2). The novelty is that the mat consists of at least two layers, the outer layer (2a) extending continuously over the entire length of the catalyst bodies (1), and the inner layer (2b) consisting of at least two sections, each associated with a catalyst body (1). The inner layer (2b) is absent from the region between the catalyst bodies. Also claimed is an expansible mat for mounting two or more catalyst bodies in a common housing. ADVANTAGE - The risk of damage to the covering over the gap between two catalyst bodies is avoided at low cost, so that the catalyst bodies can be mounted solidly and without the risk of damage in the housing.
