Title (EN) DOSING AND MIXING ARRANGEMENT FOR USE IN EXHAUST AFTERTREATMENT
(FR) AGENCEMENT DE DOSAGE ET DE MÉLANGE POUR UTILISATION DANS UN POST-TRAITEMENT D'ÉCHAPPEMENT
Abstract:
(EN) A dosing and mixing arrangement including an exhaust conduit (13) defining a central axis; a mixing conduit (30) positioned within the exhaust conduit; a dispersing arrangement (40) disposed at the upstream end of the mixing conduit; an injector (50) coupled to the exhaust conduit and configured to direct reactants into the exhaust conduit towards the dispersing arrangement; and an annular bypass (B) defined between the mixing conduit and the exhaust conduit for allowing exhaust to bypass the upstream end of the mixing conduit and to enter the mixing conduit downstream of the mesh.
(FR) La présente invention concerne un agencement de dosage et de mélange comprenant un conduit d'échappement définissant un axe central; un conduit de mélange positionné à l'intérieur du conduit d'échappement; un agencement de dispersion (par exemple, un treillis) disposé au niveau de l'extrémité amont du conduit de mélange; un injecteur couplé au conduit d'échappement et configuré pour diriger des réactifs dans le conduit d'échappement vers le treillis; et une dérivation annulaire définie entre le conduit de mélange et le conduit d'échappement pour permettre aux fumées d'échappement de contourner l'extrémité amont du conduit de mélange et de pénétrer dans le conduit de mélange en aval du treillis.
