Definitions

  • the invention relates to an atomizing device for a fluid. Fluids are usually atomized via nozzles. Depending on the application, sieve trays or other procedural installations can also be used for atomization.
  • the object of the present invention is to provide a new type of atomization device which has a high degree of atomization. This means that the continuously flowing fluid should be dispersed into the finest possible particles.
  • the atomization device has a rotationally symmetrical swirl chamber, which is formed by a jacket and two plates closing the ends thereof. At least one inlet connector is attached tangentially to the jacket and at least one outlet opening is provided, at least in one plate.
  • the fluid enters tangentially into the rotationally symmetrical swirl chamber via the inlet connections and is thereby set in rotation. While maintaining this rotation, the fluid emerges from the mostly centrally provided at least one outlet opening. Due to the inherent rotational force, the fluid emerging from the outlet opening becomes atomized very finely.
  • the ambient fluid for example air or liquid
  • pre-atomization takes place in the vortex chamber.
  • the degree of atomization can in particular be influenced by the size of the swirl chamber, the size of the outlet diameter, the length of the outlet pipe and the inlet speed resulting from pressure difference, inlet and outlet, which are influenced by the liquid supplied through the inlet nozzle.
  • an outlet opening can be provided centrally on one of the plates closing the jacket at the end.
  • an outlet opening can be provided on each of the two plates closing the jacket at the end, so that the fluid exits on two sides of this device.
  • Internals adapted to the eddy current can be provided within the vortex chamber. These internals serve to ensure that no secondary currents occur in the regions of the essentially cylindrical vortex chamber that are normally or only slightly flowed through by the eddy current, which lead to a reduction in efficiency.
  • the swirl chamber has only one outlet opening and this plate provided with the outlet opening and closing the jacket of the swirl chamber at the end is at the same time the end plate of a tube surrounding the swirl chamber.
  • the fluid for example water
  • the closure plate for the swirl chamber is the water that enters the corresponding inlet pipe opening in the surrounding pipe, is rotated within the swirl chamber and exits through the outlet opening from which the plate closing the pipe and the swirl chamber emerges.
  • This atomizing device can be attached, for example, to the end of a pipeline or to a hose as a corresponding attachment.
  • This embodiment can be modified by structurally replacing the inlet ports in the jacket with correspondingly arranged jacket openings.
  • vortex chambers are interconnected.
  • the same construction of the swirl chambers, which are attached to the jacket of the swirl chamber can in turn be attached to the open end, the outlet opening of this swirl chamber being connected to the respective inlet connection.
  • connecting lines can be attached to both outlet openings of a swirl chamber, which lead into the respective inlet connections of a second swirl chamber which has an outlet opening only on one side.
  • Another possibility of switching several vortex chambers is that they are connected in series in such a way that they have a common plate closing the respective jacket.
  • the intermediate plates between the vortex chambers can be omitted, so that several inlet levels are possible.
  • any further interconnections of two or more vortex circuits are also possible via the previously described embodiments. chambers with the previously specified features possible within the scope of this invention. When different fluids are input, more intensive and improved mixing takes place. This applies to both miscible and immiscible liquids. For example, if the vortex chambers are connected appropriately, as described above, oil, fat or gasoline can be mixed with water to achieve a high mixing quality.
  • FIG. 11 is a schematic side view of an eighth embodiment of the invention.
  • FIG. 12 shows a schematic side view of a ninth embodiment of the invention.
  • FIG. 1 The basic structure of the essential element of the atomizing device 10 can be explained on the basis of the embodiment in FIG.
  • This consists of a rotationally symmetrical swirl chamber 12 which has a jacket 14 with a circular cross section.
  • the jacket 14 has plates 16 and 18 which close these ends.
  • inlet connections 20 and 22 are attached on the jacket 14 are tan potentially offset against one another, as shown in FIG. 1, inlet connections 20 and 22 are attached.
  • the plate 18 has a central and circular outlet opening 24.
  • the fluid for example water, is introduced in the arrow direction a through the inlet connections 20 and 22 into the rotationally symmetrical vortex chamber.
  • the fluid set in rotation there emerges from the outlet opening 24 in the direction of the arrow b and is atomized after exiting the outlet opening by the centrifugal forces acting on the fluid particles.
  • FIG. 2 corresponds essentially to that in FIG. 1.
  • the outlet opening 24 which is provided in the plate 18
  • the outlet opening 26 has the same diameter as the outlet opening 24.
  • the two outlet openings have different diameters.
  • several outlet openings, which are not arranged centrally, can also be provided in the plates 16 and 18, respectively.
  • internals are provided within the rotationally symmetrical swirl chamber.
  • the sectional shape of the internals 28 is shown by dashed lines. It can be seen here that the internals are adapted to the desired vortex shape in the area of the rotationally symmetrical swirl chamber 12 closed by the plate 16. Of course, this also applies to the shaping of the internals 28 in the region of the outlet opening 24.
  • the internals 30 are adapted to the embodiment with the two outlet openings 24 and 26.
  • the shape of the internals within the swirl chamber 12 is illustrated by the dashed lines.

  • FIG. 6 shows a section through the atomizing device 10 along the section line AA.
  • the flow of the fluid to be atomized for example water, is clear from the overview of FIGS. 5 and 6.
  • the fluid is supplied via the pipeline 32 in the direction of arrow a and enters the rotationally symmetrical swirl chamber 12 via the inlet connections 20 or 22.
