A STATIC MIXER HAVING A VANE PAIR FOR THE GENERATION OF A FLOW SWIRL IN THE DIRECTION OF A PASSAGE FLOW

摘要

The static mixer (1) includes at least one vane pair (2; 2a, 2b) for thegeneration of a flow swirl (300) in the direction (30) of a passage flow(3). Edges of the vanes at the front at the leading side areperpendicular to the passage flow and parallel to a height of thepassage (10). Onflow surfaces following downstream are bent out in aconcave manner and in opposite senses. Each vane (2a, 2b) is formedas an aerodynamically designed body which includes an end wall (20),a convex side wall (21) and a concave side wall (22). The end wall hasa convex shape or a shape of a leading edge. The vane cross-sectionsperpendicular to the side walls in particular have similar shapes tocross-sections of aeroplane wings.
