Abstract:
A static laminar mixing device comprisinga plate disposed transversely of a first flow of flowable medium, said plate having at least one convergent orifice for passage of the first flow of medium therethrough; a duct coaxial of said orifice of said plate for expelling a second flow of flowable medium into said convergent orifice for mixing with the first flow downstream of said plate; a first mixer having a predetermined cross-sectional flow area, an inlet for receiving said first and second flows, and a plurality of static mixer elements disposed along a longitudinal axis thereof; and a second mixer connected with said first mixer for receiving media therefrom, said second mixer having a cross-sectional flow area that is greater than said cross-sectional flow area of said first mixer, wherein said cross-sectional flow areas of said first and second mixers are taken generally perpendicular to the direction of flow through said respective mixers, said second mixer including a plurality of static mixer elements disposed along a longitudinal axis thereof.
