A filler body with a cross channel structure for a packing column or a static mixer apparatus. The filler body is built up of layers that border on one another in which in each case channels are arranged parallel to one another. Lateral channels which are open to one another extend at boundary surfaces between adjacent layers. These lateral channels form a cross-wise arrangement. At least a portion of the layers in each case contain central channels in addition to the lateral channels. A material separation at the boundaries between the central and the lateral channels is produced in about one half of the cases by regularly arranged wall sections. The channel boundaries in the zones of the other half are open.

The packing (1) with cross channel structure for a material exchange column (2) should have a high specific separation performance. The packing is specifiable by a specific surface area, a, and an inclination angle of the passages, &phgr;. It belongs to a class of packings with a=acl and &phgr;=&phgr;cl in accordance with the following assertions: for fluids which flow in the packing, equally large fluid flows are in each case provided; a number n of theoretical separation stages per meter which can be empirically determined for the packing, namely the parameter NTSM, can be represented by a first function f1(a, &phgr;) of the variables a and &phgr;; a flow resistance which results for a gas flow which flows through the packing can be characterised by a pressure loss per meter, &Dgr;p, as a second function f2(a, &phgr;; under the auxiliary condition n=const, &Dgr;p assumes a relative minimum for which the variables a and &phgr;—in dependence on the parameter n—assume the values am(n) and &phgr;m(n) respectively; it is true that n>4.5, acl &phgr;m(n) and &phgr;cl>45°.
摘要:
An ordered column packing—in the form of packing layers containing flow channels (2)—has a foil-like material (1) with a fine structuring (10). The foil-like material is profiled with concave structure elements (3b; minus sign −) and convex structure elements (3a; plus sign +) in an alternating arrangement. An average distance “a” exists between centers of adjacent concave and convex structure elements respectively. This average distance “a” is substantially smaller than a distance between centerlines (20) of adjacent flow passages. The foil-like material has a second fine structuring in the form of regularly arranged apertures (5). An average distance “b” between centers of adjacent apertures is smaller than the average distance “a”, preferably smaller by at least 50%; and edges (51, 52) of the apertures have in each case a shape including convex and concave locations (6a, 6b).
