Abstract

Un dispositif de lavage de gaz pourvu d'un filtre comprend un module de filtrage (9) situé dans un boîtier (11) comprenant une entrée de gaz brut (1) et une sortie de gaz pur (10). Le module de filtrage (9) est constitué d'un support (2) en un matériau électroisolant poreux résistant à la chaleur sur lequel est posé un tissu métallique chauffable (3). Le support (2) est constitué de particules en céramique liées les unes aux autres, de forme sensiblement sphérique et polygonale. Le support (2) forme un corps creux fermé d'un côté. L'entrée de gaz (1) se termine dans l'ouverture du corps creux. L'ouverture du corps creux se termine dans la sortie de gaz (10). Le tissu métallique chauffable (3) et/ou le support poreux (2) sont pourvus d'une couche catalytique. Des électrodes ionisantes (4, 5) sont situées du côté de l'entrée de gaz (1) et du côté de la sortie de gaz (10) du support (2).
