Definitions

  • the invention relates to a mixing device for mixing substances which may have the same or different mass flow, the substances to be mixed flowing on both sides and along a separating plate arranged upstream of the mixing zone, to which flow-influencing means are attached on both sides.
  • the invention seeks to remedy this.
  • the invention is therefore based on the object of providing a mixing device of the type mentioned at the outset, with which large-scale longitudinal vortices can be generated, which enable fast, controlled mixing of the flowing substances within a very short distance.
  • the advantage of such a vortex generator can be seen in its particular simplicity in every respect.
  • the element consisting of three walls with flow around it is completely problem-free.
  • the roof surface can be joined with the two side surfaces in a variety of ways.
  • the element can also be fixed to flat or curved channel walls in the case of weldable materials by simple weld seams. From a fluidic point of view, the element has a very low pressure drop when flowing around and it creates vortices without a dead water area.
  • the element due to its generally hollow interior, the element can be cooled in a variety of ways and with various means.
  • a vortex generator essentially consists of three freely flowing triangular surfaces. These are a roof surface 10 and two side surfaces 11 and 13. In their longitudinal extent, these surfaces run at certain angles in the direction of flow.
  • the two side surfaces 11 and 13 are each perpendicular to the associated wall 21 of a partition plate 22, it being noted that this is not mandatory.
  • the side walls which consist of right-angled triangles, are fixed with their long sides on this wall 21, preferably gas-tight. They are oriented so that they form a joint on their narrow sides, including an arrow angle ⁇ .
  • the joint is designed as a sharp connecting edge 16 and is also perpendicular to that wall 21 with which the side surfaces are flush. Installed in a duct, the flow cross-section is hardly affected by blocking because of the sharp connecting edge.
  • the two side surfaces 11, 13 including the arrow angle ⁇ are symmetrical in shape, size and orientation and are arranged on both sides of an axis of symmetry. This axis of symmetry 17 is rectified like the channel axis.
  • the roof surface 10 lies with a very flat edge 15 running transversely to the flow around the separating plate on the same wall 21 as the side walls 11, 13. Its longitudinal edges 12, 14 are flush with the longitudinal edges of the side surfaces protruding into the flow channel.
  • the roof surface extends at an angle of incidence ⁇ to the wall 21. Its longitudinal edges 12, 14 form a tip 18 together with the connecting edge 16.
  • the vortex generator can also be provided with a bottom surface with which it is fastened to the wall 21 in a suitable manner.
  • a floor area is not related to the mode of operation of the element.
  • the connecting edge 16 of the two side surfaces 11, 13 forms the downstream edge of the vortex generator 9.
  • the edge 15 of the roof surface 10 which runs transversely to the flow around the separating plate 22 is thus the edge which is first acted upon by the channel flow.
  • the vortex generator works as follows: When flowing around edges 12 and 14, the flow is converted into a pair of opposing vortices. The vortex axes lie in the axis of the flow. The geometry of the vortex generators is chosen so that no backflow zones arise during vortex generation.
  • the swirl number of the vortex is determined by a corresponding choice of the angle of attack ⁇ and / or the arrow angle ⁇ . With increasing angles, the vortex strength or the number of swirls is increased and the location of the vortex breakdown (if desired at all) moves upstream into the area of the vortex generator itself. Depending on the application, these two angles are ⁇ and ⁇ determined by design and by the process itself. It is then only necessary to adjust the height h of the connecting edge 16 (FIG. 4).
  • the sharp connecting edge 16 in FIG. 2 is the point which is first acted upon by the channel flow.
  • the element is rotated by 180 °.
  • the two opposite vortices have changed their sense of rotation. They rotate along the roof surface and strive towards the wall on which the vortex generator is mounted.
  • the shape of the flow around the separating plate 22 is not essential for the operation of the invention.
  • the partition plate 22 could also be a straight or hexagonal or other cross-sectional shape.
  • the partition plate 22 is curved.
  • the above statement that the side surfaces are perpendicular to the wall must of course be relativized.
  • the connecting edge 16 lying on the line of symmetry 17 is perpendicular to the corresponding wall. In the case of annular walls, the connecting edge 16 would thus be aligned radially, as is shown in FIG. 3.
  • FIG. 3 partially shows a cylindrical container with a built-in partition plate 22.
  • the cross section through which flow is divided is divided into two coaxial, circular channels 20 ′ and 20 ′′ of the same channel height H by this partition plate 22.
  • the outer wall of the partition plate forms the inner channel wall 21'b of the outer channel, while the inner wall of the partition plate forms the outer channel wall 21''a of the inner channel.
  • the same channels could flow through the two channels at different speeds; or it could be flowing substances of different density or chemical composition based on must be mixed in the shortest possible way to a certain uniformly distributed concentration.
  • an equal number of vortex generators 9 are lined up with gaps in the circumferential direction.
  • the height h of the elements 9 is approximately 90% of the channel height H.
  • the annular elements, as shown in FIG. 4, are provided in the same axial plane. The flow takes place perpendicularly into the drawing plane in FIG. 3; the elements 9 are oriented so that the connecting edges 16 are directed against the flow. It can be seen that the direction of rotation of the vortices generated is descending in the area of the connecting edge, i.e. strives towards the wall on which the vortex generator is arranged. At the end of the separating plate 22, the eddy currents generated on its two sides are forced into one another, with the desired mixing occurring.
  • a further increase in the mixing quality is achieved if, as shown in FIG. 3, the connecting edges 16 of the vortex generators in the two subchannels are offset by half a division. If swirl-like vortices are used in the subchannels, it can be seen that the vortices rotating around a common radial on both sides of the separating plate combine to form a large vortex with a uniform direction of rotation.
  • the vortex generators in the two partial channels could have different heights compared to the channel height H.
  • the height h of the connecting edge 16 will be coordinated with the channel height H in such a way that the vortex generated immediately downstream of the vortex generator already reaches such a size that the full channel height H or the full height of the vortex generator is assigned Part of the channel is filled, which leads to a uniform distribution in the applied cross section.
  • Another criterion that can influence the ratio h / H to be selected is the pressure drop that occurs when the vortex generator flows around. It goes without saying that the pressure loss coefficient also increases with a larger ratio h / H.
  • FIG. 4 also illustrates how the cross section of the mixing zone d increases steeply downstream of the trailing edge of the partition plate. With this configuration, it can be seen that an intimate mixture is achieved after a short distance.
  • the invention is not only limited to the exemplary embodiments and examples shown and described.
  • the outer channel walls 21'a and 21''b could of course also be omitted - there is the possibility of combining vortex generators according to FIGS. 1 and 2, for example to to increase the growth of the mixing zone d to one side.
