Definitions

  • the invention relates to a mixer for mixing gases and others Newtonian liquids, with a flow channel and an arranged therein, the installation area influencing the flow, the installation area a vortex-generating surface with free flow, directed against the current Is leading edges, the course of which is both in the main flow direction of the Gases as well as a transverse component.
  • a static mixer is known from DE 29 11 873 C2, in which the internals from diagonally flowed, delta-shaped or circular-shaped sheets exist, on the front edges of which vortexes arise.
  • the stationary thus formed and stable vortex systems act in the wake, which too Mixing components are rolled up in layers, resulting in a rapid mixing with very low pressure drops. This way called "vortex installation areas" have because of the achievable short Mixing lines proven in practice.
  • the invention has for its object a mixer for the mixture of gases and other Newtonian liquids with extended To create possible uses.
  • the installation area is above the struts in the Flow channel supported, and at least one of the struts is in terms of their Position and / or their orientation adjustable.
  • the non-adjustable struts form a fixed point bearing around which the installation area is pivotable by means of the adjustable struts.
  • Another embodiment of the mixer according to the invention is characterized through a pivot axis of the installation surface, which is between two each other extends opposite walls of the flow channel.
  • the adjustment range the device extends up to a setting angle of 0 °, i.e. to parallel flow around the installation area by the gas.
  • Figure 1 shows in longitudinal section a flow channel 1 of, for example, rectangular Cross-section.
  • the flow channel 1 is an inhomogeneous gas or Flows through liquid mixture.
  • gases and liquids are here to understand all so-called “Newtonian liquids", i.e. Gases as well such fluids that are comparable in their fluidic properties behave to the gases.
  • each installation surface 2 in the form of a flat disk arranged.
  • the disc can be circular, elliptical, oval or delta or. triangular with tip pointing towards the flow.
  • the disc is symmetrical with respect to their center line.
  • the freely flowed against the Main flow direction 3 directed front edges 4 have both in Main flow direction 3, as well as a transverse component on.
  • each installation surface 2 is at an acute angle ⁇ to the main flow direction 3 is arranged in the flow channel 1, arise on the Front edges two vortex fields, which are circular cone-shaped downstream spread.
  • the individual vertebrae roll inwards onto the back 5 the installation area 2.
  • the vertebrae formed on the leading edges 4 are strong are shown in simplified form on the drawing, behave largely stationary, therefore do not change their position.
  • Each vortex field forms by its rotation a flow component transverse to the main flow direction 3 of the gas, due to the associated exchange of momentum across the flow direction good mixing of the gas mixture results.
  • the angle of attack ⁇ is changeable, even during the operation of the Mixer.
  • struts 6 which support the installation surface 2 with respect to the wall 7 of the flow channel 1, a strut 6a adjustable in its effective length. This is done via a Longitudinal adjustment of the strut 6a by means of a suitable hydraulic system 8.
  • Hydraulics 8 can also be another drive, e.g. an electric drive used become.
  • the other struts 6 form a fixed point bearing 6b.
  • the length of the adjustable is not Brace 6a changed, but only its base point 9 is in the direction of the flow channel 1 relocated. However, this also changes the Angle of attack ⁇ of the disk-shaped installation surface.
  • FIG 3 shows a translational adjustment of the location of the installation area in FIG Relation to the main flow direction 3 is provided. They are two separate ones There are drives, a drive for setting the angle of attack ⁇ , and a additional drive for translatory adjustment.
  • each installation area 2 has via its own drive 10, can therefore be made with respect to its angle of attack set independently of the other installation area 2.
  • each of these installation areas has its own Provide drive for the angle of attack, i.e. the angle of attack of each of the installation surfaces can be used independently of the other vortex-generating installation surfaces to adjust. Furthermore, the angle of attack can be in the same direction or how this can be seen in FIG. 6, set in opposite directions.
  • FIG. 7 shows the flue gas routing in a flue gas denitrification plant (Denox plant).
  • a flue gas denitrification plant (Denox plant).
  • the angle of attack each separately by means of preferably separate Drives is adjustable.
  • Plant the vertebrae that form on the leading edges 4 continues into a junction 12 of the channel.
  • the axial extension of the Inflow channel 11 is by means of a flap 13 adjustable in two positions closed, which inevitably creates a flow from the Inflow channel 11 results in the branch 12.
  • the junction 12 leads to a reactor (not shown in FIG. 7) with catalysts for flue gas denitrification.
  • the flap 13 is moved into the position 13 'shown in dashed lines in FIG. transferred, the branch 12 to the flue gas denitrification plant is closed. Via the bypass line 14, the flue gas gets directly into one Channel 15. Mixing of the via the inflow channel 11 in the system In this case, smoke gas coming in is not necessary. For this reason are both installation surfaces 2 with an angle of 0 ° in relation to the Main flow direction 3 operated, i.e. the installation areas are parallel to the Main flow directed and the gas flows around it completely lossless.
  • a flow channel 1 is again shown with a junction 12.
  • the installation area 2 is at the level of the junction 12 in the flow channel 1.
  • the Angle of attack ⁇ of the installation surface 2 with respect to the main flow direction 3 changeable by the flow channel 1.
  • Barriers 17, 18 in Shaped blinds provided.
  • the barrier 17 is located in the flow channel 1 downstream of the installation area 2.
  • the barrier 18 is located on Entrance to junction 12.
  • the barrier 17 In the operating state according to FIG. 8a, the barrier 17 is open, the barrier 18 completely closed.
  • the installation area 2 is with a Angle of attack ⁇ operated from about 30 ° to 60 °, so that the generated Propagate vortex fields in flow channel 1.
  • the shut-off 17 are again opened, and the barrier 18 closed.
  • the angle of attack ⁇ of the installation surface 2 is however 0 °, i.e. the installation area 2 is flowed around in parallel without loss. A Mixing does not take place.
  • the barrier 17 is closed and the Barrier 18 opened.
  • the angle of attack ⁇ is very large in this case and is between 70 ° and 85 °. In this way, the vortex fields generated propagated into the junction 12.
