15 Claims

1. A circular-shaped static mixer module having outer dimensions defined by the circumference of a circle and two generally parallel transverse planes spaced apart from each other and perpendicular to the central axis of said circle, said module comprising a series of parallel v-shaped panels spanning the interior of said circle, between said parallel planes and being parallel to a diameter of said circle, each v-shaped panel defining two planar surfaces corresponding to the legs of a v, with adjacent panels being joined to each other to form a sawtooth pattern, each of said two planar surfaces having a single row of spaced-apart perforations substantially central to the surface area of said planar surfaces, the individual perforations each defining a flow path through said static mixer module, the flow paths defined by the perforations of one of said two planar surfaces having directions which directly or in extension impinge upon or cross over the flow paths defined by the perforations of the other of said two planar surfaces.
