ABSTRACT:
A motionless mixer has a tubular casing, a fluid inlet and a fluid outlet axially spaced from one another in the casing and defining a flow direction of the fluid, a plurality of discs each having throughgoing apertures for allowing passage of the fluid. The discs have a periphery conforming to the inner cross-sectional contour of the casing. The discs are supported in the casing in a face-to-face oriented relationship to form an axially extending disc stack. The apertures in the discs form a core channel and fringe channels in the stack for dividing a fluid stream into a core stream and fringe streams in a first zone, for dividing the core stream into fringe streams in a second zone and for centripetally combining the fringe streams into a central stream in a third zone. A mechanism prevents the discs from angular displacements relative to one another.
