The fluid mixing device of the present invention comprises: a vertically disposed vessel having a fluid inlet means and a fluid outlet means permitting the flow of fluid generally vertically through the vessel; a horizontally disposed first plate having a first surface, a second surface and a central opening in the plate; a cylindrical cap having a vertical side wall extending vertically from the first surface of the first plate, sized and positioned to cover the central opening in the first plate, the cap having a plurality of angular slots in the side wall to direct the flow of fluid passing therethrough in a swirling direction toward the central opening in the first plate; a horizontally disposed second plate having a first surface, a second surface and a plurality of openings in an annular ring around the periphery of the second plate, the first surface of the second plate facing but spaced apart from the second surface of the first plate. A horizontally disposed circular table is positioned on the first surface of the second plate and axially aligned with the central opening in the first plate. h plurality of conduits extend vertically from the second surface of the second plate and communicate with the peripheral openings therein, the conduits having slots therein oriented at predetermined angle with respect to the radius of the vessel. A third horizontally disposed plate, having a central opening therein, is spaced apart from the second surface of the second plate and defines a jet stirred mixing zone there between. A horizontally disposed fluid distribution plate is spaced apart from the third plate and has a plurality of openings therein whereby fluids contacting the plate are distributed by flowing through the openings therein. Means for introducing a fluid stream, from an external source, to the vessel on the first surface side of the first plate is also provided.
