Abstract

A static mixer distributes substances introduced into a flow duct as homogeneously as possible in a flow medium. The intention is to achieve complete intermixing over the shortest possible path distance. The static mixer includes a multiplicity of deflection elements which are small in relation to the diameter of the flow duct. The deflection elements are disposed in mutually parallel rows aligned transversely to the axis of symmetry of the flow duct. The deflection elements of each row are inclined equidirectionally in a direction parallel to the row and in counterdirection to the deflection elements of the respectively directly adjacent rows. The static mixer can be used for gaseous and liquid media.
