Abstract
The vortex packing for an apparatus designed as a mass exchange column or a static mixer is build up of face-shaped structural elements. These structural elements define a point lattice whose lattice planes, situated in cross-sections of the apparatus, form base grids of quadrilaterals. Each of the quadrilaterals represents an equatorial periphery of an octahedron and the polar vertices of these octahedra are positioned at the points of neighbouring lattice planes. The octahedra have either all open faces or alternately open and closed faces. According to the invention the packing is built of parallel layers (3) of a sheet-like material having substantially triangular elementary areas (8,9). Part of these elementary triangles (9) have on two sides cut edges (30) and are deflected in a flap-like manner about folding edges (15) out of the sheet area. The structural elements of the packing are formed by association or connection of the elementary triangles (8,9) in pairs.
