摘要： A fluid dispensing, mixing and removing apparatus arranged in a column between beds of granular solids, and comprising at least one device for collecting a primary fluid, said device being provided with at least one first screen (7) and at least one pipe (3) for injecting or removing at least one secondary fluid (B), at least one redistribution device including at least one second screen (8), a baffle (4) arranged between the first and second screens (7, 8), at least one mixing chamber (12) comprising a primary fluid feeding device (10) and at least one mixture outlet (11), at least one redistribution and/or collection chamber (13) comprising at least one device (9) enabling each secondary fluid (B) to flow through to the mixing chamber (12), a collecting space (Ec) defined by the first screen (7), the mixing chamber (12) and the baffle (4), and at least one redistribution space (Ed) defined by the baffle (4) and the second screen (8). The mixture outlet (11) comprises at least one suitably calibrated aperture causing sufficient head loss to confine turbulence within the mixing chamber (12).
