Abstract:
A static mixer with profiled layers which are arranged in a ring space and which contain mutually crossing flow channels which are inclined relative to a central axis (z), wherein a fluid mixture is to be transported in the axial direction in the presence of a mixing action,wherein each layer extends over a surface which forms an at least substantially closed periphery transverse to the axis (z) and each layer comprises equivalent channels which extend on an inner or outer side of the layer over substantially equal distances from a first to a second cross-section of the ring space, so that each channel imposes an azimuthal velocity component onto the fluid mixture which flows through it which is substantially equally large for all equivalent channels; wherein an approximately parallelogram-shaped piece of surface lies in the layers in each case between an outer and an inner folding edge; and wherein a diagonal folding edge is included in this piece of surface.
