Abstract:
1. A distributor device for distributing a downwardly flowing poly-phase mixture, comprising at least one gas phase and at least one liquid phase, above at least one bed of granular solid, said device comprising: a. at least one tray located above a bed of granular solid; b. a plurality of fluid distribution conduits for receiving liquid and gas phases, each of said conduits comprising at least one upper cross section for flow through which a gas phase can enter said mixer conduit, and at least one lower cross section for flow through which a mixture of gas and liquid communicate with a bed of granular solid, said fluid distribution conduits having one or more lateral openings for flow over at least a portion of their height through which a liquid phase can enter said fluid distribution conduit, and having a cylindrical passageway for gas having an inlet connected to the upper cross section and having an outlet extending below the lateral openings for the liquid phase, thereby forming an annular passageway for the liquid phase; c. said upper cross section for flow allowing the majority of the gas phase of said mixture to pass and said lateral openings for flow allowing the passage of the liquid phase into said fluid distribution conduits and at least a portion of the gas phase; and d. a venturi nozzle having an inlet and an outlet fixedly coupled to and co-axially aligned with the lower cross section of the conduit for accelerating and dispersing the liquid and gas phases passing out of the conduit.
