A device for distributing a poly-phase mixture comprises: at least one gas phase and at least one liquid phase, said mixture being in downflow mode through at least one bed of granular solid, comprising: at least one tray (P) located above one of said beds of granular solid, a plurality of mixer conduits (21) for said liquid and gas phases, each of said conduits comprising at least one upper cross section for flow (22) and at least one lower cross section for flow (23) allowing the mixture formed inside said mixer conduits to communicate with a bed of granular solid, said mixer conduits being provided over a portion of their height with one or more lateral cross sections for flow (26), said upper cross section for flow (22) allowing the majority of the gas phase to pass and said lateral cross section for flow (26) allowing the passage of the liquid phase into said mixer conduits and/or at least a portion of the gas phase respectively, said device comprising at least one jet disturber type dispersive system (28) with a controlled porosity below the lower cross section for flow (23) and above the bed of solid.
