Continuous, static mixing apparatus

Claim 1

A mixing apparatus comprising an elongated, cylindrical mixing chamber having a hollow body and opposed end walls, said mixing apparatus further including a first entry port extending through a first of said end walls and into said mixing chamber, a first nozzle plate mounted within said mixing chamber and adjacent said first entry port, a second entry port extending through a second of said end walls and into said mixing chamber, a second nozzle plate mounted within said mixing chamber and adjacent said second entry port and spaced from said first nozzle plate, a discharge port extending through said body and into said mixing chamber, said discharge port positioned longitudinally on said hollow body between said nozzle plates, said entry ports and nozzle plates positioned to direct a fluid flowing through an entry port, through an adjacent nozzle plate and toward an opposite nozzle plate, each nozzle plate having an inner face, an opposed outer face, and a plurality of bores extending therethrough between said inner face and outer face and spaced about the center of said nozzle plate, with the inner face of each nozzle plate directed toward said adjacent end wall and with the outer faces of the nozzle plates directed toward each other, said bores each diverging outwardly toward said body and at an angle relative to the longitudinal axis of the chamber as the bore extends from said inner face to said outer face, said bores being skewed with respect to a radial line extending outwardly from the center of said nozzle plates, and said bores of each nozzle plate being skewed in the same direction, such that a fluid entering one entry port will contact and mix thoroughly within said mixing chamber with a fluid entering the opposite entry port and the mixed fluids will exit said mixing chamber through said discharge port, whereby fluids passing through said bores have a component of motion outwardly toward said body of said mixing chamber, a component of motion inwardly toward an opposite nozzle plate, a rotary component of motion relative to the radius of said mixing chamber, and a rotary component of motion in a direction opposite to that of fluids passing through the bores of an opposite nozzle plate.
