Static mixer

In combination with a hollow tubular conduit defining an internal longitudinal passageway wherein said conduit includes an internal wall surface, a static mixing device positioned in said conduit and within a fluid stream having a longitudinal flow direction with said passageway, comprising a plurality of mixing vane members forming a set thereof, said vanes spaced generally circumferentially equidistantly within said conduit and radially inwardly extending from said conduit internal wall surface towards the center of said conduit, each of said vane members including a generally oblong plate of planar extent with a generally straight base edge attached to said internal conduit wall and further including a leading edge upstanding from a base edge forward portion to a peak from which, in turn, a rearwardly downwardly curved tailing edge extends and terminates proximal the rear portion of said base edge, each of said plates including a generally triangularly-shaped cap attached and conforming to said curved trailing edge thereof with the cap apex aligned with said leading edge peak so as to form cap undersurfaces and cap top surfaces.
