compact fluid mixing device in a reactor downflow

摘要

compact fluid mixing device in a reactor downflow comprising: - at least one means of substantially horizontal collection (5) provided with a duct collection vertical (7) for receiving fluids; - a mixing chamber ring (9) downstream of the collection means (5) in the direction of fluid flow, said chamber having an inlet end directly connected to said collection duct (7) and an outlet end (10) for the passage of fluid, said outlet end (10) being located along the radial direction of the reactor vessel (1), the mixing chamber being located annular (9) in the periphery of the reactor vessel (1 ) and the length of said chamber is defined by the angle formed by the planes passing through the two ends of said chamber between 130 and 200 degrees being comprised, and - at least one injection means (8) located in said conduit collection, said injection means being located at the level of the inlet end of the annular mixing chamber (9); - a tray horizontal predistribution (11) having at least one chimney (13), said tray being positioned downstream of said chamber (9) at a distance d2 in the direction of fluid flow.
