Abstract

La présente invention concerne un dispositif pour éliminer des particules et des composés gazeux polluants d'un flux gazeux (F1, F2) provenant de l'air présent dans un milieu confiné ou semi-confiné, comprenant un arrangement formé par une pluralité d'enceintes (10, 20, 30) disposées en série, chaque enceinte (10, 20, 30) comprenant des ouvertures (11, 21, 31) aménagées pour permettre la traversée du flux gazeux de part et d'autre de l'arrangement, et chaque enceinte comprenant au moins des moyens (50, 60, 61) pour générer des zones d'écoulement turbulent et des zones d'écoulement non turbulent dudit flux gazeux (F1, F2). De plus, l'arrangement d'enceintes (10, 20, 30) comprend au moins : une première enceinte (10) comprenant des moyens pour contrôler l'humidité (13, 13') du flux gazeux, une deuxième enceinte (20) comprenant des moyens (23, 24) de photo-oxydation et/ou de photo-catalyse des composés gazeux polluants, une troisième enceinte (30) comprenant des moyens d'adsorption et/ou d'absorption des composés gazeux polluants. L'invention concerne en outre un procédé pour éliminer des particules et des composés gazeux polluants d'un flux gazeux provenant de l'air présent dans un milieu confiné ou semi-confiné.
