Definitions
- the invention relates to a mixer for an exhaust system of an internal combustion engine for mixing an exhaust gas flow.
- the additional medium is mixed as evenly as possible with the exhaust gas to produce a homogeneous exhaust gas additive mixture.
- a mixer in the exhaust system between an injection device for introducing the additional medium and the exhaust gas aftertreatment device.
- the mixer for a device for selective catalytic reduction of exhaust gases, wherein the mixer is used for uniform distribution of a introduced into the exhaust stream reducing agent.
- the mixer has radially inwardly projecting mixing elements, which are flowed through for electrical heating with an electric current.
- the mixing elements are designed in the form of blades.
- the vanes have a central slot so that they have a substantially U-shaped course and can be connected at their radially outer ends with a power source.
- the object of the present invention is to provide a mixer with an improved geometry for mixing the exhaust gas.
- the mixer according to the invention has several guide vanes arranged side by side transversely to a longitudinal axis.
- the guide vanes have guide surfaces, which each face an inlet side of the mixer and which are inclined relative to the longitudinal axis.
- Each vane has at least one passage opening.
- Each passage opening is provided with a deflection vane with a deflection surface facing the inlet side of the mixer.
- the deflecting vanes cover at least partially each one of the passage openings in the axial direction.
- the deflection surfaces are each inclined obliquely relative to the guide surface in the direction of the inlet side of the guide surface.
- the guide vanes are preferably made of sheet metal.
- the turning vanes can be made of sheet metal.
- the turning vanes are each cut integrally from one of the vanes and reshaped, the vanes being directed toward the entry port, i. on the inflow side, projecting from the respective guide surface of the guide vane.
- the vanes may be arranged circumferentially about the longitudinal axis side by side.
- the guide vanes are in this case preferably uniformly over the Um- arranged distributed catch.
- the mixer can be rotationally symmetrical.
- the guide vanes are arranged parallel to each other transversely to the longitudinal direction.
- the mixer has a rectangular cross-section.
- the passage openings of all guide vanes are arranged on a common plane.
- the deflecting vanes can be set in such a way that an exhaust gas flow from the deflecting vanes is respectively guided through the passage opening of an adjacent guide vane.
- the mixing effect in the exhaust gas flow is further improved.
- the mixer may include a mixer housing in which the vanes are arranged.
- the mixer housing is in this case preferably adapted to the cross section of an exhaust pipe of the exhaust system and inserted into the exhaust pipe.
- the mixer housing When arranged around the circumference arranged deflecting vanes, the mixer housing has a round, preferably circular or elliptical, cross-section and can be used in a correspondingly shaped exhaust pipe.
- the mixer housing In the case of vanes arranged parallel to one another, the mixer housing preferably has a rectangular cross-section which is inserted into an exhaust pipe with a corresponding cross-section.
- the mixer housing may include at least one spacer radially projecting from an outer surface of the mixer housing.
- at least one gap is thus formed between the outer surface of the mixer housing and the exhaust pipe. This gap is then also flowed through by the exhaust gas flow, so that the mixer housing is not only flowed around inside, but also outside. This allows the entire mixer to heat up faster, thereby reducing buildup on the mixer, for example, from crystallizations of the aqueous urea solution.
- the mixer housing may in this case also be made of sheet metal, wherein the spacer elements are integrally formed in the mixer housing in the form of beads.
- the object is further achieved by an exhaust system of an internal combustion engine, wherein the exhaust system has an exhaust pipe, in which a mixer of the foregoing kind is arranged.
- an injection device for introducing an additional medium can be arranged in the exhaust system, wherein the injection device is arranged upstream of the mixer. Downstream of the mixer can be arranged in this case an exhaust aftertreatment device.
- the injection device has at least one nozzle hole. With several nozzle holes can produce multiple spray jets, which can be used for a more targeted spraying of certain areas of the mixer.
- the at least one spray jet is preferably oriented such that at least 50%, preferably at least 75%, of the deflecting vanes are directed with respect to the sprayed quantity of the additional medium. In this way, the degree of mixing can be further improved.

- Figure 4 is a plan view of the mixer of Figure 2;
- Figure 5 is a perspective view of a second embodiment of a mixer
- FIG. 6 shows a schematic side view of the mixer according to FIG. 5.
- the exhaust system 3 comprises an exhaust gas line 4, in which an exhaust gas aftertreatment device 5, for example an SCR catalytic converter for the selective catalytic reduction of nitrogen oxides, is arranged. Upstream of the exhaust aftertreatment device 5, an injection device 6 is provided, which injects an additional medium, such as, for example, an aqueous urea solution, into the exhaust gas flow of the exhaust line 4 in order to allow the selective catalytic reaction in the SCR catalytic converter.
- an exhaust gas aftertreatment device 5 for example an SCR catalytic converter for the selective catalytic reduction of nitrogen oxides
- a mixer 7 is arranged between the injection device 6 and the exhaust gas aftertreatment device 5.
- the mixer 7 is designed as a static mixer 7, which has no moving and driven components for mixing, but achieves a mixing effect exclusively by the flow of exhaust gas.
- FIGS. 2 to 4 show a first embodiment of a mixer in different perspectives and will be described together below.
- the mixer 7 is flowed through in the arrow direction with exhaust gas and has an upstream inlet side 8 and a downstream outlet side 9.
- the exhaust gas flow thus flows through the mixer 7 in a main flow direction along a longitudinal axis L of the mixer 7, wherein the direction of the exhaust gas flow is deflected in detail within the mixer 7 and a turbulence also occurs downstream of the mixer 7.
- the mixer 7 has a mixer housing 10, which is tubular and has an oval cross-section ( Figure 4).
- the mixer housing 10 may also have a different cross-sectional shape, such as a substantially circular cylindrical cross-sectional shape.
- the mixer housing 10 is inserted into a correspondingly shaped exhaust pipe 4.
- the mixer housing 10 is aligned concentrically to the longitudinal axis L.
- a rigid hub 1 1 is arranged concentrically to the longitudinal axis L within the mixer housing 10, wherein the hub 1 1 is designed rod-shaped and is aligned in the direction of the longitudinal axis L.
- On the hub 1 1 a plurality of guide vanes 12 are fixed, which are arranged in the circumferential direction around the longitudinal axis L L side by side and are uniformly distributed over the circumference.
- the vanes 12 are connected to both the hub 1 1 and with the mixer housing 10. It is also conceivable that the guide vanes 12 are connected only to the mixer housing 10 and no hub 1 1 is provided.
- the guide vanes 12 form an inlet-side guide surface 13 facing the inlet side 8.
- the guide surface 13 is inclined at an angle to the longitudinal axis L.
- the guide surface 13 and the longitudinal axis L thus form an angle of greater than 0 degrees to less than 90 degrees.
- the vane 12 has, in the illustrated embodiment, a first vane section 14 and a second vane section 15.
- the baffle 13 of the first vane section 14 is made smaller relative to the longitudinal axis L than the baffle 13 of the second vane section 15. This means that the second vane section 15 deflects the exhaust gas flow in the circumferential direction more than the first vane section 14 and thus generates a greater turbulence of the exhaust gas flow ,
- the guide surface 13 of the first vane section 14 and the longitudinal axis L enclose in one embodiment an angle of 30 degrees to 60 degrees.
- the baffle 13 of the first vane section 14 and the longitudinal axis L subtend an angle of approximately 45 degrees.
- the guide surface 13 of the second vane section 15 encloses with the longitudinal axis L in an embodiment an angle of 70 degrees to approximately 90 degrees. In the embodiment shown, the Guide surface 13 of the second vane portion 15 and the longitudinal axis L an angle of approximately 90 degrees.
- the guide vanes 12 each have a passage opening 16 in the first guide blade section 14. Each passage opening 16 is associated with a deflecting blade 17, which covers the passage opening 16 in axial view ( Figure 4), the respective passage opening 16.
- the deflection vanes 17 have deflection surfaces 18 which face the inlet side 8 of the mixer 7 on the upstream side, wherein the deflection surfaces 18 are aligned obliquely at an angle to the longitudinal axis L and are made stronger relative to the longitudinal axis L than the guide surfaces 13 of the first guide blade sections 14 Deflection surfaces 18 are in this case employed almost as far with respect to the longitudinal axis L as the guide surfaces 13 of the second guide blade sections 15.
- the deflection surfaces 18 are also employed in such a way with respect to the longitudinal axis L that they deflect the exhaust gas flow in such a way that they enter the passage opening 16 on the downstream side of the adjacent guide blade 12 on the downstream side 9 and flow through them.
- all passage openings 16 are arranged on a common imaginary plane, wherein the plane is arranged perpendicular to the longitudinal axis L.
- the guide vanes 12 are made of sheet metal material, wherein the turning vanes 17 are cut out of the guide vanes 12.
- the guide vanes 17 are not separated out of the respective guide blade 12 along a bending edge 19, but integrally connected thereto and formed in the direction of the inlet side 8.
- the mixer housing 10 has at least three, in the embodiment shown four, spacer elements 20 which project radially from an outer surface 21 of the mixer housing 10.
- the spacer elements 20 are integrally formed with the mixer housing 10, wherein the mixer housing 10 is made of a sheet metal material.
- the spacer elements 20 are formed by beads in the mixer housing 10.
- FIG. 4 indicates, in a broken line, the cross-section of an exhaust gas line 22, into which the mixer 7 is inserted.
- the mixer housing 10 thus lies with the spacer ments 20 on an inner surface of the exhaust pipe 22, wherein in the circumferential direction in each case between the spacer elements 20 and in the radial direction between the outer surface 21 and the exhaust pipe 22, a gap 23 is formed.
- the gap 23 is also traversed by exhaust gas and allows a rapid heating of the mixer housing 10 to avoid buildup.
- Figures 5 and 6 show a second embodiment of a mixer 107, details which correspond to details of the first embodiment being provided with reference numerals which are increased by the value 100 and described therein.
- the mixer 107 of the second embodiment is made substantially rectangular, wherein the mixer housing has a rectangular cross-section.
- the mixer housing 1 10 four vanes 1 12 are arranged, which are arranged parallel to each other transversely to the longitudinal axis L.
- the operation of the mixer 107 corresponds to the second embodiment of the first embodiment.
- the injection device 6 can have one or more nozzle holes. With several nozzle holes, several spray jets can be generated, which can be used for a more targeted spraying of certain areas of the mixer 7.
- the at least one spray jet is preferably oriented such that at least 50%, preferably at least 75%, of the deflected vanes 17 or 11 are directed with respect to the sprayed quantity. In this way, the mixing can be improved. LIST OF REFERENCE NUMBERS
