  • An internal mixture of liquid and propellant gas is characteristic in fluidically connected chambers in which the propellant gas Relaxed several times on the way up to leaving the nozzle and again is compressed. In this way, a very good one takes place in the atomizing chamber Premix before mixing the nozzle with the conical Annular gap emerges, and is further dispersed during this expansion. Because of this pressure jump, the liquid is atomized very finely and as a hollow cone entered the surrounding space.
  • DE 26 45 142 describes a method for generating a current of described at least two mixed and atomized fluids, in which First the liquids and a propellant in a first injector-like one Flow passage merged, mixed and pre-atomized. The the resulting gas-liquid mixture is then accelerated and strikes a baffle or reflection device after leaving the nozzle body. In this reflection and impact zone, the second mixing stage there is another mixture and atomization before the atomized mixed fluid leaves the nozzle in the form of an open parachute.

  • the gutter is advantageous on the inside with a sharp tear-off edge Mistake.
  • Another improvement is that an annular gap or in the nozzle head radial gas holes to create a gas curtain within the Nozzle gap emerging spray cone are arranged. Another stabilization of the spray cone can be through a cylindrical, enveloping the spray cone Gas curtain can be reached. For this purpose are in the nozzle flange Axial gas holes provided. Through this fluidic Measures are prevented that atomized liquid particles to the Get to the surface of the nozzle and there a product structure that hinders spraying takes place.
  • the shape of the spray cone can advantageously be varied in that the Nozzle gap is adjustable with regard to its gap width.
  • the essential components of the multi-phase mixing nozzle are the nozzle flange 1, the atomizing chamber 2 and the nozzle head 3.
  • the two liquids F 1 and F 2 reach the atomizing chamber 2 via distribution elements which are arranged on a circle in the nozzle head 1.
  • the distribution elements in turn consist of Y-shaped bore branches, with 2 leg lines and one common foot line.
  • collecting channels 4 and 5 for the two liquids F 1 and F 2 and a gas collecting channel 6 for the supply of the propellant gas are arranged.

  • the two leg lines 7 and 8 run towards each other at an acute angle and merge into the common foot line 9, which opens into the atomizing chamber 2.
  • the distribution elements for the liquid F 1 are constructed analogously.
  • One leg line 10 opens into the liquid collection channel 4, the other leg line 11 is again connected to the gas collection channel 6.
  • the two leg lines 10 and 11 are in turn brought together to form a foot line 12, which opens into the interior of the atomizing chamber 2.
  • the propellant gas strikes the liquid F 2 via the leg line 11 and the liquid F 1 via the leg line 8.

  • the annular outlet gap 20 on the nozzle head 3 is arranged at an obtuse angle against the nozzle axis. Since the pressure losses in compression and expansion in the expansion spaces 19 connected in series decrease the pressure in the flow direction, the volume flow increases with the mass flow remaining the same.
  • the pressurized multiphase mixture is atomized for the last time to form a hollow cone 22 (see FIG. 3). The swarm of droplets consisting of the multiphase mixture thus leaves the nozzle head 3 through the opening 21 along a conical surface.

  • the central inner tube 25 can be an inert gas via the nozzle flange 1 are supplied (air or nitrogen), which via the distribution space 28 through the Annular gap 27 and the gas holes 29 flows out. That way, inside of the spray cone is a rotationally symmetrical gas curtain with a radial Flow component generated.
  • This gas curtain has the task that in the Fill area of the cone cap 26 forming negative pressure area. Without these There is a tendency for the swarm of drops to have a hollow cone shape collapsed below the exit gap 21. The atomization would then take the form assume a full cone, one in the vicinity of the outlet gap belly-shaped expansion occurs.

  • multi-phase mixing nozzle With the help of the described multi-phase mixing nozzle, it is possible to use two or several liquids with very different physical properties to mix and atomize intensely. Because of the extremely low mean Dwell time in the entire multi-phase mixing nozzle in the range from 5 to 100 ms lead to slow chemical reactions between the liquids no impairment of the atomization quality. It was also found that even polymerizing liquids due to the extremely short residence time in the multi-phase mixing nozzle mixed and the mixture without problems can be atomized. The multi-phase mixing nozzle practically enables in-situ Mixing and atomization. Polymerizing liquids could e.g. Not premixed in a tank and then atomized.
