static mixer with a pair of blades for generating a flow swirl in the direction of a flow

摘要

STATIC MIXER GIFTED FROM A PAIR OF SPADES FOR GENERATING A FLOW TURBILLION IN THE DIRECTION OF A PASS FLOW. The present invention relates to a static mixer (1) including at least one pair of blades (2; 2a, 2b) for generating a flow swirl (300) in the direction (30) of a flow ( 3). The edges of the paddles in front of the lead side are perpendicular to the flow of passage and parallel to a height of the passage (10). Surfaces in the flow following the flow direction are curved in a concave shape and in opposite directions. Each shovel (2a, 2b) is formed as an aerodynamically designed body that includes an end wall (20), a convex side wall (21) and a concave side wall (22). The end wall has a convex shape or a leading edge shape. The blade cross-sections perpendicular to the sidewalls are in particular similar in shape to the airplane wing cross-sections.
