Title
(EN) DEVICE FOR REDUCING ATMOSPHERIC POLLUTION BY EXHAUST GAS
(FR) DISPOSITIF POUR REDUIRE LA POLLUTION ATMOSPHERIQUE DUE AUX GAZ D'ECHAPPEMENT
Abstract
(EN)
The device for reducing atmospheric pollution by exhaust gas has a cylindrical casing (2) in turn having an inlet (4) for the unpurified exhaust gas and an outlet (6) for the purified exhaust gas; a tubular scrubbing cartridge (8) housed inside the casing (2), interposed between the inlet (4) and the outlet (6), and defining a cylindrical inner chamber (36) and, together with the casing (2), an annular-section outer chamber (34) surrounding the scrubbing cartridge (8); an annular-section inlet conduit having transverse dimensions increasing towards the outer chamber (conical shape) (18) connecting the outer chamber (34) to the inlet (4); and a cup-shaped body (14) connecting the inner chamber (36) to the outlet (6), so as to define an inward exhaust gas purifying path through the scrubbing cartridge (8).
(FR)
L'invention concerne un dispositif permettant de réduire la pollution atmosphérique due aux gaz d'échappement, ce dispositif comprenant: une enveloppe cylindrique (2), munie d'un orifice d'entrée (4) pour les gaz d'échappement destinés à être épurés et d'un orifice de sortie (6) pour les gaz d'échappement épurés; une cartouche d'épuration (8) tubulaire logée à l'intérieur de l'enveloppe (2) et placée entre l'orifice d'entrée (4) et l'orifice de sortie (6), de manière à définir une chambre intérieure cylindrique (36), et à former, avec ladite enveloppe (2), une chambre extérieure (34) à section annulaire, autour de la cartouche d'épuration (8); un conduit d'admission (18) à section annulaire, dont les dimensions transversales augmentent au niveau de la chambre extérieure (de forme conique), afin de raccorder cette chambre extérieure (34) à l'orifice d'entrée (4); et enfin un corps en forme d'entonnoir (14), conçu pour relier la chambre intérieure (36) à l'orifice de sortie (6), et ainsi définir un parcours d'épuration des gaz d'échappement à travers ladite cartouche, de l'extérieur vers l'intérieur.
