Definitions

  • the invention relates to an atomizer arrangement for dispensing a finely atomized fluid, with at least one spray opening for dispensing a fan jet of the fluid.
  • Atomizer arrangements of the type mentioned are known.
  • Modern fluid injection systems for example, for fuel or exhaust aftertreatment fluids, such as urea-water solutions, require that a fluid be finely atomized during injection.
  • a reduction effect for NO x only with a well-atomized reducing agent fluid, such as Ad Blue sufficiently high.
  • Known atomizer arrangements usually have one or more spray-hole bores for atomizing the fluid, for example EP 498 931 . DE 19 507 285 . DE 19 504 882 or DE 19 517 988 ,
  • the DE 10 2005 007 805 A1 discloses an atomizer structure having a flow passage for supplying a fluid to ejection openings formed in the flow passage, the ejection openings being covered in the flow direction by material bridges.
  • inflowing fluid is divided into individual streams, which flow around the material bridge and meet again between material bridge and spray openings before penetrating the spray opening and collide head-on.
  • an antechamber which can be directly flowed through and which effects a collision flow of the fluid, directly in front of the injection orifice, in accordance with the characterizing features of claim 1. is trained. Immediately before the injection orifice therefore an antechamber is provided, which causes a collision flow of the fluid. This vestibule is partially directly flowed through by the fluid to be atomized along a direct fürströmungspfads.
  • the antechamber is designed such that a fluid flowing into the antechamber is partially deflected in such a way that a collision flow is created.
  • a collision flow is to be understood as a flow in which at least two flow paths of the fluid in the antechamber are generated in such a way that they meet one another or collide with one another.
  • at least two flow paths deflected in the antechamber collide with one another and with the direct flow path in the region of the injection opening. Since the collision flow is generated immediately before the injection orifice, and since the antechamber can be flowed through directly, the direct flow-through path causes the different flow paths to essentially collide with one another in the injection orifice. A purely frontal collision of currents is thereby advantageously prevented, so that no flow energy is lost. As an evasive movement, the fluid spreads downstream of the collision flow as a fan beam.
  • the advantageous embodiment ensures that a particularly favorable fan beam propagation is formed and the fluid is atomized very finely. Due to the direct flow path, the fan beam reaches a particularly wide penetration depth.
  • the fan jet is thus both extremely finely atomized due to the advantageous embodiment of the atomizer arrangement and, moreover, also achieves a wide penetration depth or jet length.
  • the spray-discharge opening is formed on a spray-off structure, in particular spray-off plate.
  • the Abspritz Jardin or Abspritzplatte can be integrated in a simple manner, for example in an injection valve or in a metering valve.
  • the antechamber is formed on a Anström für, in particular Anströmplatte.
  • the antechamber can be integrated in a simple manner, additionally or alternatively to the spray-off structure in the injection valve or metering valve.
  • the Abspritz Design adjacent to the Anström Cook in particular adjacent to each other adjacent or directly integrally formed with each other.
  • the Ab mousse homemade and the Anström Cook are thus formed directly adjacent to each other.
  • This can be realized, for example, by the already mentioned formation of the Abspritzregal as Abspritzplatte and the Anström Cook as Anströmplatte.
  • the atomizer assembly thus formed is easily usable for injection or metering valves.
  • An opening in the Anströmplatte then forms the antechamber in the assembled state of the atomizer.
  • the Abspritz Design and the Anström gleich are formed directly in one piece with each other. This can be prevented in a particularly simple manner, an unwanted outflow of fluid between Abspritz réelle and Anström Cook.
  • a particularly simple assembly of the atomizer assembly results.
  • the ejection opening is a slot opening.
  • the (fan) shape of the atomized fluid jet is essentially predetermined, and on the other hand, a particularly favorable collision flow for the atomization of the fluid is made possible by the slot-shaped spray opening.
  • the colliding flow paths of the fluid generated or directed by the antechamber extend perpendicular to the longitudinal extension of the slot opening.
  • the vestibule is designed as a rotationally symmetrical vestibule or as Schlitzvorraum.
  • a favorable for the atomization collision flow is made possible in a simple manner.
  • the ejection opening is formed as a slot opening and the antechamber as a slot anteroom
  • the geometric longitudinal extent of the slot opening extends transversely to the geometric longitudinal extent of the slot antechamber.
  • the slot opening and the slot antechamber are thus advantageously perpendicular or at an acute or obtuse angle one above the other, wherein a flow cross-section, is formed by the overlapping cross section of slot opening and Schlitzvorraum.
  • the slot antechamber directs or channels the fluid to the slot opening or the exposed flow cross-section. On both sides of the flow cross-section thereby the converging flow paths, which collide in the flow cross-section.
  • the walls in the spray orifices thus diverge in the direction of flow.
  • the ejection opening has a concave opening base, viewed in the flow direction.
  • the antechamber has walls which converge toward one another in the (direct) flow direction, whereby the fluid is directed in a particularly advantageous manner and the colliding flow paths are generated.
  • the converging walls of the antechamber are expediently walls which are aligned parallel to the longitudinal extent of the antechamber designed as a slot antechamber.
  • At least two ejection openings are provided.
  • two fan beams are generated, and increases a possible volume flow of the fluid.
  • the at least two ejection openings are designed to be divergent in a spouting manner.
  • two spray openings designed as slit openings a further sputtering advantage arises, wherein the divergent co-spraying ensures that the fan beams do not suck each other for aerodynamic reasons, whereby the sputtering result would be worsened.
  • two mutually divergently spraying spray-orifices are obtained, in which two slit openings are closer to the - seen in the longitudinal direction - ends of Schlitzvorraums as at the center.
  • a greater volume of fluid is directed to the slot openings than from the ends thereof.
  • the at least two ejection openings are inclined relative to one another in order to generate divergent fan beams.
  • the Figures 1A and 1B show a first example of an advantageous atomizer arrangement 1 in a plan view of an inflow side 2 (FIG. Figure 1A ) and on a discharge side 3 ( FIG. 1 B) ,
  • the substantially circular atomizer assembly 1 consists of a in the FIG. 2 illustrated, formed as a Anströmplatte 4 Anström Modell 5 and one in the FIG. 3
  • the spray plate 4 has a slot-shaped opening 8, which is formed centrally in the Anströmplatte 4.
  • Abspritzplatte 6 has two mutually parallel, as slot openings 9 and 10 formed, spray openings 11 and 12. Of course, even more spray holes could be seen before.
  • the spray plate 6 and the Anströmplatte 4 superimposed on the atomizer 1, wherein the spray plate 6 and the Anströmplatte 4 are aligned such that the geometric longitudinal extension of the slot openings 9 and 10 of the spray plate 6 transversely or perpendicular to the geometric longitudinal extension of the opening 8 of Run on the flow plate. This results in overlapping regions of the opening 8 with the slot openings 9 and 10, which each form a flow cross-section 13, 14.
  • the opening 8 of the Anströmplatte 4 by resting the Anströmplatte 4 on the spray plate 6, an antechamber 15 which is due to the slit-shaped design of the opening 8 is a Schlitzvorraum 16.
  • FIG. 4A shows a sectional view of the atomizer assembly 1 along in the Figure 1A marked line AA.
  • FIG. 4A shows the superimposed Anströmplatte 4 and spray plate 6 in a sectional view along the longitudinal extent of the opening 8.
  • the opening 8 intersects with the slot openings 9 and 10
  • the antechamber 15 or slot vestibule 16 can be flowed through directly by a liquid medium in the direction of the arrows 17, ie without deflection.
  • FIG. 4B shows a sectional view of the atomizer assembly 1 along in the Figure 1A drawn section line BB, which extends along the longitudinal extension of the slot opening 10 of the spray plate 6.
  • the fan-like propagation or expansion of the jet in the direction of flow is indicated by arrows 19.
  • a particularly finely atomized fluid is also produced in aqueous fluids, such as reducing agents such as Add-Blue.
  • Water has a relatively high surface tension, which hinders a jet disintegration or the lateral expansion of a jet in the flow direction. Compared to gasoline, for example, water has a surface tension that is 3 times higher.
  • the ejection openings 11, 12 or slot openings 9, 10 of the spray plate 6 are formed so as to be spaced parallel to one another such that the fan beams generated are generated divergently relative to one another, as already described above.
  • the spray plate 6 and the Anströmplatte 4 are integrally formed with each other.
  • FIGS. 5A to 8B show a further example of the atomizer assembly 1, which substantially corresponds to the embodiment described in the preceding figures, so that only the differences should be discussed here.
  • the spray plate 6 and the Anströmplatte 4 are each formed by a square silicon plate 20, 21.
  • the opening 8 and the slot openings 9 and 10 are prepared by wet etching of the silicon or silicon plates 20, 21.
  • oblique slot walls 22, 23 and 24 are formed obliquely along the crystal plane of the silicon.
  • FIGS. 5A and 5B show the atomizer assembly 1 in a plan view of the inflow side 2 ( FIG. 5A ) and on the discharge side 3 ( FIG. 5B ).
  • FIG. 6 shows the Anströmplatte 4 formed by the silicon plate 20, and the FIG. 7 the spray plate 6 formed by the silicon plate 21 in a plan view.
  • the silicon plate 20 and the silicon plate 21 so placed on each other that the slot walls 24 and 22 and 23 - seen in cross-section - as in the Figure 8A represented are widening / diverging away from the support plane away.
  • the FIG. 8B shows the atomizer assembly 1 of Figures 5A in a further sectional view along the section line DD.
  • the silicon plates 20, 21 have particularly smooth surfaces.
  • the wet-etched opening 8 and the wet-etched slot openings 9 and 10 have correspondingly smooth surfaces. From the resulting low surface adhesion, the surfaces of the spray plate 6 and the Anströmplatte 4 dirt or deposit repellent act.
  • This has particular advantages in the use of the atomizer assembly 1 in an injection or metering valve which is exposed to high heat and / or soot.
  • silicon withstands high temperatures.
  • silicon is chemically resistant, so that the atomizer assembly 1 is not attacked by a fluid to be injected, such as Add-Blue.
  • the Figures 9A and 9B show in a further example an integrally formed atomizer arrangement 25 in a cross-sectional representation ( Figure 9A ) and in a longitudinal section ( FIG. 9B ).

  • the antechamber 26 can be at least partially directly flowed through by a fluid in the direction of the arrow 30. Due to the rotationally symmetrical design and the planar base 27 of the antechamber 26, a collision flow is generated, which leads to an advantageous fan beam, as described in the preceding examples.
  • the Figures 10A and 10B show in a cross-sectional representation ( Figure 10A ) and in a longitudinal representation ( FIG. 10B )
  • the vestibule 26 has a concave-shaped base 27.
  • the injection opening 28 is, as in the FIG. 10B shown, also formed as a slot opening 29, with the difference that it has a concave curved opening base - seen in the longitudinal direction - and - seen in cross section - in the injection direction (30) widening / diverging opening walls 32 has.
  • the spray opening 28 can be created, for example, in a simple manner by means of a disk cutter.
  • the rotationally symmetrical vestibule 26 with a concave bottom 27 is easy and inexpensive to produce through a bore.
  • FIG. 11 shows a cross-sectional view of the atomizer assembly 25 of Figures 9A and 9B with the difference that two ejection openings 28 or slot openings 29 are provided, which are advantageously designed divergently to each other spouting, so that the generated fan beams do not affect each other negatively, as already described above.
