<p>Mixing elements (11), (12) for a motionless mixer comprise passage tubes (13), (17) through which fluids flow and helical blades (14), (18) formed in the passage tubes so as to be integral therewith. The interior of the passage tubes (13), (17) are partitioned by the blades (14), (18) to form a plurality of fluid passages (15, 16), (19, 20). The blade extends from one end of the passage tubes (13), (17) to the other in the longitudinal direction of the passage tube to be twisted helically clockwise (right-handed) or counterclockwise (left-handed). The corner portions (22) of the fluid passages are rounded. The end edges (21) of the blade (14), (18) are curved in the direction of the thickness and rounded. The motionless mixer is formed by alternately and longitudinally coupling right- and left-handed rotation type mixing elements (11), (12). The mixing elements (11), (12) are so arranged that the facing end edges of the blades (14), (18) of each two adjacent mixing elements (11), (12) cross at right angles.</p> |
