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).

Abstract: A method for manufacturing a packing made of a three-dimensional netlike structure which constitutes an internal structure of device which performs material transfer, heat exchange or mixing between gases, liquids or gas and liquid, the internal structure being divided in a plurality of chambers or channels connected to one another is provided. The three-dimensional net-like structure is made of a plurality of unit structures which are arranged continuously in vertical and horizontal directions of the three-dimensional net-like structure. Each of the unit structures is formed by converging and dispersion of three or four line elements. The method comprises a step of forming a converging section of the unit structure where the three or four line elements converge by binding the three or four line elements together.

Abstract: An apparatus is disclosed for the exchange of substances and/or heat between and/or mixing of gaseous and/or fluid substances wherein the flowing substances are guided repeatedly through permeable walls (1, 2, 3 and 4) running essentially parallel to the direction of the main flow (14 and 17). According to the apparatus, this will be achieved by the spacing means (5) of lesser permeability which are disposed alternately in the flow channel (13) between the permeable walls (1, 2, 3 and 4). The permeable walls preferably consist of fabrics which are placed in movement or into oscillation by the flowing media. For a more effective exchange, the walls are provided with areas (1, 2, 3 and 4) of variable density of fabric, whereby the denser areas are preferably located near the spacing means (5).

Abstract: The present invention provides a device for the even distribution of liquids onto column areas which comprises distributor troughs with overflow slits and liquid guide elements, hairpin shaped guide elements having a pair of arms arranged at a distance from each other disposed in each overflow slit which is wider at the bottom and adjacent to the outside face of the trough or on lugs attached thereto, the free ends of the guide elements being led to the outside, to a level below that of the bottom of the trough.
