Definitions

  • the invention relates to an ordered packing for heat and / or mass transfer columns, a packing unit consisting of at least two packing layers.
  • European patent application EP 1 074296 describes an orderly pack in which the individual pack layers are each composed of two individual pack layers with different geometries.
  • a packing layer with a narrow geometry arranged at the bottom is combined with a packing layer with a wide geometry arranged at the top.
  • the packs are operated in such a way that the lower pack layer is driven in a bubble state with a high mass exchange.
  • the coarse packing layer arranged above acts as a droplet separator and additionally fulfills the function of a conventional packing with a liquid film flowing over it.
  • the object of the invention is to improve the gas and / or liquid distribution with a simple structure in a pack of the type mentioned at the outset to increase the heat and / or mass exchange.
  • this object is achieved in that the lower packing layer has packing layers which have a greater density and thus a larger surface area than the other packing layers of the same packing layer.
  • these packs according to the invention do not have a uniform geometry of the individual layers, but are specifically designed to be uneven in the horizontal direction, in the vertical direction or preferably in the horizontal and at the same time vertical direction.
  • the packs are operated in such a way that the lower pack layer is driven in a bubble state with a high mass exchange, the coarse pack layer arranged above acts as a droplet separator and additionally fulfills the function of a conventional pack over which a liquid film flows.
  • the packing layers with a greater density and thus a larger surface form a greater resistance for the gas coming from below, so that the gas flows upwards more slowly there and as a result the liquid in these packing layers reaches the bottom more strongly. This results in liquid circuits and gas cycles within the packing layer, which find an optimal distribution of the liquid. This also ensures that the liquid gets down in sufficient quantities.
  • FIG. 1 shows a first embodiment of a pack unit in a cutout
  • FIG. 2 shows a second embodiment of the lower pack layer
  • FIG. 3 shows a third embodiment of the lower pack layer
  • Figure 4 shows a fourth embodiment of the lower pack layer.
  • Each floor has at least one packing unit 1, each of which has an upper 2 and a lower packing layer 3.
  • the first exemplary embodiment according to FIG. 1 has a conventional upper packing layer 2 in a cross-channel structure, in which the individual packing layers 4 have a uniform geometry with the same specific surface both in the horizontal direction and in the vertical direction.
  • the upper packing layer 2 is of lower density and has a smaller specific surface.
  • the lower pack layer 3 is of greater density and has a larger specific surface.
  • FIGS. 1 and 2 show sections of packing layers according to the invention, in which the lower packing layer 3 packing layers 4a, 4b have at least two specific surfaces of different sizes in the horizontal direction.
  • two packing layers 4b with the higher specific surface are installed adjacent. Between these layers 4b with the larger specific surface area are 1 to about 10, preferably 3 to 6, adjacent layers 4a with a smaller specific surface area.
  • the specific surface area of the layers 4a with the smaller specific surface area corresponds to the geometries customary in the art with a specific surface area of approximately 100 to 1200 m 2 / m 3 .
  • the layers 4b with the larger specific surface have a specific surface larger by a factor of about 2.
  • the reason for this very large specific surface lies in the function deviating from the usual internals used in distillation technology.
  • the tight, dense packing layers 4b can be made from different materials, which can also have perforations, for example from sheet metal, expanded metal or wire mesh.
  • both packing layers 4a, 4b have perforations at the lower end over approximately 10 to 50% of the height, which allow the liquid to pass from the narrow channels into the wide channels.
  • the free opening cross section should be about 5 to 20% based on the total area of the packing layers.
  • the narrow packing layers 4b protrude at the lower end of the narrow packing layer by approximately 2 to 50 mm, preferably 5 to 20 mm, the layers at the upper end at the same height (FIG. 3) or at a different, in particular lower End height (Figure 4).

Abstract

La présente invention concerne un garnissage organisé pour colonnes d'échange de chaleur et / ou de matière. Une unité de garnissage (1) est constituée d'au moins deux strates (2, 3), la strate inférieure (3) comportant des couches (4b) de garnissage qui présentent, par rapport aux autres couches (4a) de garnissage de la même strate (3) de garnissage une densité supérieure et, partant, une surface supérieure.
