Abstract:
A differential injector for mixing in a flow device comprising:a substantially cylindrical fluid flow body having a venturi disposed therein and first and second wall portions, said venturi being disposed and aligned concentrically with said substantially cylindrical fluid flow body, for providing primary fluid flow through said venturi, the venturi having an inlet port, a throat portion and an outlet port; a secondary fluid port for supplying a secondary fluid for mixing with the primary fluid, said secondary fluid port being disposed within said first wall portion of the substantially cylindrical fluid flow body, for delivering the secondary fluid to a plurality of flow channels, said plurality of flow channels being disposed within said second wall portion of the substantially cylindrical fluid flow body, said plurality of flow channels supplying the secondary fluid at a point which is downstream of the throat portion, said plurality of flow channels being aligned and including first and second groups of flow channels, the first group of flow channels being disposed between the second group of flow channels and an interior surface segment of the second wall portion of said substantially cylindrical fluid flow body, the first and second groups of flow channels terminating at respective first and second outlet ports within the substantially cylindrical fluid flow body, the first and second outlet ports having a segment of the interior surface segment of the second wall portion disposed therebetween, the interior surface segment of the second wall portion including at least one surface irregularity to increase turbulence and the production of torroidal vortices to improve mixing of the primary fluid and the secondary fluid.
