Definitions

  • the invention relates to a static mixer with a plurality of deflection elements arranged in a flow channel
  • Static mixers are generally installed in pipelines or in other flow channels and serve to distribute substances previously introduced into the pipeline or into the flow channel as homogeneously as possible in the flow medium. For example, it can be used to mix various previously introduced gases. It can also be used to evenly distribute liquid or dusty substances in a gas stream. Static mixers can also be used in liquids.
  • Known static mixers consist of one or two deflection elements - mostly triangular sheets - which are anchored more or less obliquely in the flow path (see Balke Dürr, special print C56, from VGB Krafttechnik H8 / 1983, pages 676 to 678).
  • a static mixer has also become known in which several small deflection elements are arranged next to one another in a plane perpendicular to the axis of symmetry of the gas channel.
  • static mixers good mixing of the gases or substances previously injected into the gas stream can already be achieved at a relatively short distance from the deflection elements.
  • it is a peculiarity of such static mixers with relatively small deflection elements that local concentration differences can be compensated for relatively well and also quickly.
  • large-scale differences in concentration for example between two opposite sides of the flow channel, can only be compensated for to a very inadequate extent.
  • the dimensions of the deflection elements provided for this purpose are at least as large as the distance between the rows, i.e. also like the cross section of the subchannel.
  • the invention has for its object to develop a static mixer in which the pressure drop caused is particularly low.
  • a static mixer with a shorter mixing distance is also able to equalize large-scale as well as local concentration differences.
  • the deflection elements can be inclined by about 10 ° to 45 ° about axes perpendicular to the direction of the rows and perpendicular to the axis of symmetry of the flow channel. This measure contributes to faster mixing.
  • the rows can extend from one boundary wall to the opposite boundary wall of the flow channel. This promotes a large-scale concentration balance.
  • a particularly simple construction results from the fact that the deflection elements are fastened on a supporting grid extending transversely to the axis of symmetry of the gas channel. This construction is relatively simple, stable and space-saving to install.
  • a particularly intimate mixing is achieved if two in each case in a further development of the invention
  • Adjacent rows of deflection elements are arranged in close proximity to one another in pairs.
  • the turbulence in the region of these deflection elements is greatly intensified, which is equivalent to a further intensification of the local intimate mixing.
  • FIG. 1 shows a plan view of a in a rectangular flow channel, here a gas channel 1, built-in static mixer 2 according to the invention.
  • the viewing direction is chosen against the flow direction of the gas stream 4.
  • FIGS. 2 and 3 show the side views, that is to say FIGS. 2 and 3.
  • a support grid 8 is inserted in the gas channel 1, perpendicular to its axis of symmetry 6, which consists of struts 10 which are perpendicular to one another 11, in the exemplary embodiment made of flat steel.
  • Triangular deflection elements 12 made of sheet metal are welded on at the crossing points of the struts 10, 11 of the support grid 8.
  • deflection elements 12 are welded onto the outflow side of the support grid 8. It can be seen from FIGS. 1 and 2 that the deflection elements 8 are inclined by approximately 30 ° with respect to the axis of symmetry 6 of the gas channel 1. 1 shows that the deflection elements 12 are arranged in rows on the support grid 8 and the deflection elements of each row 14, 15, 16, 17, 18 are inclined in the same direction in the direction of the row with respect to the main flow direction 4. The deflection elements of the respectively adjacent rows are inclined in the opposite direction, but by the same angle of inclination. It is also noticeable that the deflection elements are much smaller in their dimensions or with their edge length than the dimensions of the gas channel 1. In the exemplary embodiment, the edge lengths of the deflection elements 12 are less than one tenth of the width or length of the gas channel 1. The edge lengths can be up to a fifth of the mean transverse extent of the flow channel.
  • the deflection elements 12 of each row 14, 15, 16 induce , 17, 18 a cross flow 22 in the gas channel 1, which is a limitation the same extends to the opposite limit.
  • the immediately adjacent rows of Deflection elements 12 produce such a transverse flow 22 from one boundary of the gas channel 1 to the opposite one, but with the opposite flow direction.
  • a large-scale mass transfer is achieved across the entire gas channel 1 at the shortest possible distance.
  • the opposite directions of flow of the gas cause ring vortices 20 at their boundaries, which ensure intimate local mixing.
  • the gas flows responsible for the large-scale mixing across the gas channel are shown in FIG. 1 with straight arrows 22, the vortices responsible for the local intimate mixing are indicated in FIG. 1 by circular arrows 20.
  • FIG. 4 shows a plan view of another static mixer 32 according to the invention installed in a tubular gas channel 30.
  • the static mixer comprises a support grid 34, which is installed perpendicular to the axis of symmetry 33 of the gas channel 30, and is fastened to struts 36, 37 which are perpendicular to one another Deflection elements 38.
  • the cross struts 36 are welded here under the longitudinal struts 37 and the deflection elements 38 are not welded to the longitudinal struts 37 at the points of intersection of the struts of the supporting grid, but in between.
  • the deflection elements 38 are arranged in rows and the deflection elements of each row are identical to one another and inclined in the opposite direction to the deflection elements of the respectively adjacent row.
  • this static mixer 32 When this static mixer 32 is in operation, when the deflection elements 38 are flown against by the gas stream 39, it is similar to the exemplary embodiment in FIGS 3 through each row of equally inclined deflection elements 38, a transverse flow directed across the gas channel and crossing the entire gas channel 30 is generated, which is exactly opposite to the respectively adjacent transverse flow. For this purpose, compare the straight arrows 40 in FIG. 4. Local small vortices are formed between two adjacent cross currents 40, as the circular arrows 42 show, which ensure intimate local mixing.
  • the arrangement of the deflection elements between the crossing points of the struts 36, 37 is somewhat simpler in terms of production technology than that according to the exemplary embodiment according to FIGS. 1 to 3. With regard to the mixing function, there is no significant difference between the two variations.
  • Both static mixers 2, 32 can also be installed in a rectangular gas channel 1 and vice versa instead of in a tubular gas channel 30.
  • FIG. 7 shows a top view of another static mixer 54 according to the invention installed in a rectangular gas channel 50 perpendicular to its axis of symmetry 52.
  • the deflection elements 56, 57 are fastened to a support grid 58 made of struts 60 oriented perpendicular to one another.
  • the deflection elements 56, 57 are arranged in rows, wherein the deflection elements of one and the same row are all inclined transversely to the gas flow 62 and the deflection elements 56, 57 of the respectively adjacent row are all inclined in the opposite direction to the gas flow.
  • FIG. 10 shows a top view
  • FIG. 11 shows a modification of the static mixer 54 of FIG. 7 in side view.
  • a flat support grid 70 made of struts 72 oriented perpendicular to one another is arranged in a rectangular gas channel 74 perpendicular to its axis of symmetry 76.
  • the same deflection elements 78, 79 as in FIG. 7 are arranged in rows and two deflection elements 78, 79 of immediately adjacent rows are pressed close together and inclined in the opposite direction to the primary gas flow 75.
  • the pairs of deflection elements 78, 79 fastened along the same struts 72 are each arranged in mirror image, so that non-mirror image pairs of deflection elements can only be found in rows diagonally to the support grid 70.
  • this static mixer 80 is therefore particularly suitable for intensive mixing of substances which are already mixed to a certain extent evenly in the inflowing gas stream.
  • the static mixers disclosed can be used not only in process engineering for uniform mixing of different material flows, that is to say gases, liquids and / or solids transported therein. With such static mixers, even more uniform mixing of different reactants can be carried out in the chemical industry over relatively short distances.
  • the denitrification of flue gases in power plants and in waste incineration can be favorably influenced by mixing the reducing agent - mostly NH 3 - with the flue gas very evenly.
