Definitions

  • the invention relates to a honeycomb body, in particular a catalyst carrier body for the catalytic conversion of exhaust gases in an exhaust system, in particular for an exhaust system of an internal combustion engine, preferably for Otto engines, which has a plurality of channels and each channel with its one end opens into a central channel.
  • Honeycomb bodies of this type with a catalytically active coating are also referred to as radial catalysts. Such a device is described in the magazine "VDI-Nachzincate" No. 38 of September 24, 1993, p. 11 "Kat on the way to high-tech”.
  • the present invention is based on the object of further developing a honeycomb body in such a way that, for. B. as a catalyst support body improves the catalytic conversion of exhaust gases. Furthermore, it should be easy to manufacture.
  • the honeycomb body according to the invention is characterized in that the channels are arcuate from a central channel to the outside. run. With this design, the channels become longer without the external dimensions of the carrier body having to be changed.
  • the carrier body can be designed flexibly with the same catalytically active surface.
  • the channels are delimited by adjoining disks, with at least some of the disks having a macro structure which forms the lateral delimitation of the channels and which, for. B. can have a height of about 0.5 to 5 mm.
  • This structure of the honeycomb body has the advantage that it is easy to manufacture, since the macrostructure e.g. can be applied to the disks by embossing. Another advantage of this structure can be seen in the fact that the (catalytically active) surface can be adapted relatively easily to the intended use of the catalyst carrier body by the number of disks or the channels.
  • the macro structures on individual panes can be curved differently.
  • the carrier body can have channels whose curvature is the same, but which have a different cross section.
  • the catalyst carrier can also be adapted to the requirements placed on it in that the catalyst carrier body is constructed from disks which have macrostructures with the same and / or different curvature. This enables a modular structure of the carrier body and a defined distance between the panes can be achieved by alternating the arrangement of panes with and without a macrostructure or of panes with differently curved macrostructures.
  • the individual channels expediently run from the central channel to the outside in an involute manner. Because of their definition, the involutes have the same distance everywhere, so that the free flow cross section of the channels in the flow direction is approximately constant.
  • the device by an alternating arrangement of disks with a macrostructure and disks with a microstructure, the macro and the microstructure crossing at an angle.
  • the advantage of such a further development is that the flow in the channel is disturbed by the microstructure, which leads to turbulence within the flow. Turbulence in the flow has the advantage that the flow layer and the diffusion layer on the catalyst surface are disturbed, as a result of which the mass transfer between the exhaust gas and the catalyst is improved.
  • microstructure can e.g. B. by forming embossments which are arranged concentrically to the central channel.
  • Microstructure is understood here to mean that the structure has only about 5-30% of the height of the macrostructure.
  • the panes with a macrostructure can also have microstructures running at an angle to them in order to increase the effectiveness of a catalytic conversion.
  • the exhaust gas flow is advantageously carried out in such a way that the carrier body is flowed through from the inside to the outside.
  • the central channel is connected to the exhaust gas inlet opening.
  • This flow guide has the advantage that the operating temperature required for the catalytic conversion can be reached relatively quickly in the center of the support body. As a result, the device has a relatively high response speed.
  • FIG. 1 shows schematically a first exemplary embodiment of a device in longitudinal section
  • FIG. 2 shows a second exemplary embodiment of a device in longitudinal section
  • FIG. 3 shows a pane in plan view
  • Figure 4 shows a disc with a microstructure in plan view.
  • FIG. 1 shows a device 1 for the catalytic conversion of exhaust gases in an exhaust system.
  • the device comprises a housing 2 in which a catalyst carrier body 3 is arranged.
  • the catalyst carrier body 3 has a multiplicity of channels 4. Each channel 4 opens into a central channel 5.
  • the central channel 5 is connected to the exhaust gas inlet opening 6 of the housing 2.
  • the exhaust gas inlet opening 6 or the housing 2 is connected to an exhaust pipe 7, which is part of an exhaust system.
  • the housing 2 has an exhaust gas outlet opening 8 which is connected to a further exhaust pipe 9.
  • the end 10 opposite the exhaust gas inlet opening is closed.
  • the carrier body 3 is arranged at a distance from the housing 2, so that there is a gap 11 between the carrier body 3 and the housing 2.
  • the exhaust gas flows into the exhaust pipe 9 via the gap 11 and through the exhaust gas outlet opening 8 of the housing 2.
  • FIG. 1 Another exemplary embodiment is shown in FIG.
  • the second exemplary embodiment differs from the first exemplary embodiment according to FIG. 1 in the exhaust gas flow guidance.
  • the exhaust gas flowed through the carrier body from the inside to the outside.
  • the exhaust gas flows through the carrier body 3 from the outside inwards. - (l -
  • a guide body 13 is provided in the exhaust gas inlet area 12, which deflects the exhaust gas flow towards the gap 11. From a fluidic point of view, such a guide body is advantageous because it can reduce the pressure losses.
  • the carrier body 3 is also electrically heated.
  • a voltage source 14 is connected to the inside of the carrier body 3 via the central channel 5.
  • the outer surface of the carrier body 3 is also connected to the voltage source 14.
  • the carrier body 3 is constructed from a multiplicity of adjoining disks.
  • FIG. 3 shows a pane 15 which has a macro structure 16.
  • the macro structure 16 forms the lateral boundary of the channels 4.
  • the channels 4 run outward from a central region 17 in an approximately involute manner.
  • the disk can also have a microstructure 20 running at an angle to the macrostructure.
  • FIGS. 4 and 5 A disk with a microstructure is shown in FIGS. 4 and 5.
  • the micro structure comprises concentrically formed embossments 17 to the central area.
  • the central region 17 represents an opening which forms the central channel 5 when the carrier body is assembled.
  • Microstructures can be formed on only one side or preferably on both sides of a pane. They preferably follow one another at a distance of 0.5 to 10 times the height of the macrostructure.
  • honeycomb bodies according to the invention can also be used in unfavorable space conditions.
