Device for guiding the flow of a liquid used for material and/or energy exchange in a wash column

Abstract

The invention relates to a wash column for material and/or energy exchange between media, especially between a liquid trickling down and a gas or a lighter liquid rising in a counter-current. The invention especially relates to a novel structural packing that comprises liquid guide elements (19) in the form of wires or threads that form substantially rhomboid masses with vertical axes in imaginary surfaces (21) and that surround, for example in a polygonal grid, substantially free, vertical flow channels (22) for the counter-flowing gas. The nodes (18) of the liquid guide elements (19) are located at the respective points of intersection of a horizontal cross-section grid. The distance between the guide elements or the size of the meshes is chosen such that the liquid does not form film curtains and flows off only in defined flows, linearly along the guide elements (19). At the ends of the packing, the guide elements (19) for the introduction of liquid and for the draining-off of liquid are bundled step-wise to common strands for introducing or draining off liquid.
