Claims23
A static mixer comprising a hollow housing defining an internal longitudinal passageway, having a longitudinal axis, within which a plurality of planar mixer elements are arranged, one after the other such that they are stacked in the housing to form an assembly of mixer elements, said planar mixer elements are comb- or star shaped planar elements with a central bar on which at least two teeth are provided on each of both sides of the bar and wherein adjacent mixer elements within the static mixer are rotated about the longitudinal axis of the longitudinal passageway of the housing by an angle α with respect to each other so that one tooth of a mixer element in each case reaches into the intermediate space between two teeth of a respectively adjacent mixer elements.
A static mixer, comprising a hollow housing defining an internal longitudinal passageway, having a longitudinal axis, within which a plurality of planar mixer elements are arranged, one after the other such that they are stacked in the housing to form an assembly of mixer elements, said planar mixer elements are comb shaped and having:
- a) first and second longitudinal components, each having two transverse edges and two longitudinal edges;
- said two longitudinal components being spaced apart from each other and connected to each other by a third longitudinal component having two transverse edges and two longitudinal edges, one transverse edge of said third longitudinal component being connected to one longitudinal edge of one of said first and second longitudinal components, and the other transverse edge of said third longitudinal component being connected to one longitudinal edge of the other of said first and second longitudinal components, and optionally having one or more further longitudinal components between and spaced apart from said first and second longitudinal components and from each other, and joined to each other and to said first and second longitudinal components by said third longitudinal component, or
- said mixer elements are star shaped and having:
- b) first and second longitudinal components which intersect each other to form a figure
- wherein γ represents an angle of from 10° to 170°.
