Title (EN) A DEVICE FOR REDUCING POLLUTANTS IN A GASEOUS MIXTURE
(FR) DISPOSITIF DE RÉDUCTION DE POLLUANTS DANS UN MÉLANGE GAZEUX
Abstract:
(EN) Described is a device (1) for reducing pollutants in a gaseous mixture comprising: • a containment body (2) having an inlet portion (3) for the gaseous mixture and an outlet portion (4) for the gaseous mixture, the containment body (2) imposing on the gaseous mixture a fixed direction of flow (D), • at least one filtering unit (10) comprising a photocatalytic filter (7) interposed, along the fixed direction of flow (D), between a first light source (6a) and a second light source (6b), both having a wavelength in the visible spectrum (400-700 nm), the photocatalytic filter (7) comprising a photocatalytic nanoparticle coating and the nanoparticle coating comprising titanium dioxide doped with a nitrogen doping agent. • a unit (5) for straightening the flow before the filtering unit (10).
(FR) L'invention concerne un dispositif (1) de réduction de polluants dans un mélange gazeux. Ce dispositif comprend: • un corps de confinement (2) ayant une partie d'entrée (3) pour le mélange gazeux et une partie de sortie (4) pour le mélange gazeux, le corps de confinement (2) imposant au mélange gazeux une direction d'écoulement fixe (D), • au moins une unité de filtrage (10) comprenant un filtre photocatalytique (7) interposé, le long de la direction d'écoulement fixe (D), entre une première source de lumière (6a) et une seconde source de lumière (6b), toutes deux ayant une longueur d'onde dans le spectre visible (400-700 nm), le filtre photocatalytique (7) comprenant un revêtement de nanoparticules photocatalytiques et le revêtement de nanoparticules comprenant du dioxyde de titane dopé avec un agent dopant à l'azote,• une unité (5) de redressement de l'écoulement avant l'unité de filtrage (10).
