A packing element, for use in mass and/or heat transfer columns or towers through which a gas and/or liquid flows, includes at least one first group of strips having a plurality of exchange surfaces formed by the surfaces of half-wave-shaped and/or wave-shaped strips. The periodic length l1 of a strip of the first group of strips adjoins a second group of strips with a periodic length l2, which are matched to each other in such a way, that the two adjoining strips are in contact with each other at at least one point, enabling a liquid transfer between these two strips. The at least one strip extends from a first end bridge to a second end bridge, wherein the two end bridges run along the transverse direction of the packing element. At least one strip of the packing element is torsioned about a longitudinal torsion line of the packing element. |

1. A packing element, for use in mass transfer and/or heat transfer columns or towers, through which a gas and/or liquid flows, wherein the packing element confined by a first and a second outside comprises a plurality of exchange surfaces which are formed by the surfaces of wave-shaped strips having half-waves, wherein the packing element comprises at least one first group of strips, comprising at least one half-wave-shaped and/or wave-shaped strip with a first periodic length l1, and at least one adjoining second group of strips, comprising at least one wave-shaped strip with a second periodic length l2, wherein the wave-shaped strips extend along an imaginary axial plane of the packing element and at least one strip extends between a first end bridge and a second end bridge, the two end bridges extending in a transverse direction of the packing element, wherein the periodic length l1 of a strip of the first group of strips adjoining the second group of strips, and the periodic length l2 of a strip adjoining said strip of the first group of strips, are matched to each other in such a way, that the two adjoining strips are in at least one of physical and capillary contact with each other at at least one point, enabling a liquid transfer between these two strips, wherein at least one strip extends from a first end bridge to a second end bridge, and wherein the two end bridges run along the transverse direction of the packing element, wherein at least one strip of the packing element is torsioned about a torsion line running in the longitudinal direction of the packing element, wherein the torsion of the strip along said torsion line increases starting from the first end bridge, is at maximum in the area of a first amplitude maximum of the strip, decreases in the area between said amplitude maximum and the central section of the packing element, increases, starting from said central section, up to a second amplitude maximum of said strip and decreases in the area between said amplitude maximum and the second end bridge, and that all strips are in contact with each other in this central section in such a way that a persistent connection for the liquid is formed from the first outside to the second outside of the packing element. |
