Elements of the lining of layers comprising, on two of their faces of the channels crusaders and their characteristics

摘要

Packing element, intended in particular for columns for transferring material, for heat exchange and for mixing two fluids, formed by a layer of material of thickness "E" which is substantially constant between one face A and one face B which are substantially parallel, the said face A comprising at least one open channel and, preferably, a plurality of open channels, of depth Pa, extending completely through, on the said face A overall in a direction AA' and the said face B comprising a plurality of open channels, each having, independently of one another, a depth Pb, extending completely through on the said face B overall in a direction BB' making an angle alpha with the direction AA' of 10 to 170 degrees, and the sum of the depths Pa + Pb being equal to a value from 0.7 to 1.3 times the value of the thickness "E" of the layer. Packing is obtained, for example, by superposing wafers formed by the juxtaposing packing elements juxtaposed such that the channels make an angle greater than zero degrees and less than 90 degrees with the axis of the column into which the said packing is placed.
