Definitions

  • the invention relates to a Zweistoffzerstäubungsdüse for spraying a liquid with the aid of a pressurized gas with a mixing chamber, an opening into the mixing chamber liquid inlet, an opening into the mixing chamber compressed gas inlet and an outlet opening downstream of the mixing chamber, wherein an outlet opening surrounding the annular gap for the discharge of compressed gas at high speed is provided.
  • FIG. 1 shows a dual-fluid nozzle with internal mixing according to the prior art.
  • a fundamental problem with such nozzles results from the fact that the walls of the mixing chamber 7 are wetted with liquid.
  • the liquid which wets the wall in the mixing chamber 7 is driven by the shear stress and pressure forces as liquid film 20 to the nozzle mouth. It is plausible to assume that the walls are blown dry towards the nozzle mouth due to high flow velocity of the gas phase and that only very fine droplets are formed from the liquid film.
  • the theoretical and experimental work of one of the inventors see the attached bibliography, has shown that liquid films on walls can still exist as stable films without dripping even when the gas flow which drives the liquid films to the nozzle orifice reaches supersonic speed. And this is also the reason why it is possible to use liquid film cooling in rocket thrusters.
  • a liquid is introduced parallel to a central longitudinal axis 24 in the direction of arrow 1.
  • the liquid is passed through a lance tube 2 extending concentrically to the central longitudinal axis 24 and enters a mixing chamber 7 at a liquid inlet 10.
  • the lance tube 2 and the mixing chamber 7 are concentrically surrounded by an annular chamber 6, which is formed by means of a further lance tube 4 for the supply of the compressed gas to the two-fluid nozzle.
  • this annular chamber 6 compressed gas is introduced according to the arrow 15.
  • a with respect to the central longitudinal axis 24 radial peripheral wall of the mixing chamber 7 has a plurality of compressed gas inlets 5, which are arranged radially to the central longitudinal axis 24. Through these compressed gas inlets 5, compressed gas can enter the mixing chamber 7 at right angles to the liquid jet entering through the liquid inlet 10, so that a liquid / air mixture is formed in the mixing chamber 7.
  • Adjoining the mixing chamber 7 is a frusto-conical constriction 3, which forms a convergent outlet section, followed by a frustum-shaped extension 9 after a narrowest cross section 14, which forms a divergent outlet section.
  • the frusto-conical enlargement 9 ends at the outlet opening or the nozzle mouth 8.
  • a two-fluid nozzle is known in which first a tubular flow profile is to be formed within the nozzle, wherein in the interior of the tubular airfoil, the air is guided.
  • the tubular flow profile is achieved by introducing a partial flow into the liquid channel of the nozzle, wherein this partial stream of the air is then guided into the interior of the latter after the tubular flow profile has been generated.
  • Compressed gas should escape from an annular space in the region of the outlet opening, which then breaks up the walls of the tube-like flow profile produced in drops.
  • the two-fluid nozzle described thus represents a two-fluid nozzle with external mixing, since a disassembly in drops takes place only outside the nozzle.
  • the invention is intended to provide a two-component atomizing nozzle and a method for spraying a liquid with a two-component atomizing nozzle, in which a uniformly fine droplet spectrum can be achieved both in the edge region and in the jet core.
  • a Zweistoffzerstäubungsdüse for spraying a liquid with the aid of a compressed gas with a mixing chamber, an opening into the mixing chamber liquid inlet, an opening into the mixing chamber pressure gas inlet and an outlet opening downstream of the mixing chamber, wherein the one surrounding the outlet opening annular gap for the escape of pressurized gas high speed is provided, are provided in the control means and / or at least two pressure gas sources, so that the pressure of the annular gap supplied gas pressure and the pressure of the pressure gas flowing through the pressure gas inlet into the mixing chamber pressure gas is independently adjustable.
  • the volume of a drop having a diameter reduced by a factor of three is only one-seventeenth of a large drop. Without entering into the well-known relationships here, it should be clear to the person skilled in the art that this results in considerable advantages with regard to the required construction volume of evaporative coolers or of sorption systems, for example for the flue gas purification. With the additional annular gap atomization, therefore, a much finer droplet spectrum can be generated with the same expenditure of energy.
  • the annular gap air quantity is 10% to 40% of the total atomizing air quantity.
  • the total pressure of the air in the annular gap is advantageously 1.5 bar to 2.5 bar absolute.
  • the total pressure of the air in the annular gap would advantageously have to be so high that, when expanding to the pressure level in the vessel, approximately sound velocity is achieved.
  • control means and / or at least two compressed gas sources are provided, so that a pressure of the annular gap supplied compressed gas and a pressure of the pressure gas opening into the mixing chamber through the compressed gas inlet is independently adjustable.
  • the outlet opening is formed by means of a peripheral wall, whose extreme end forms an outlet edge and the annular gap is arranged in the region of the outlet edge.
  • the pressure gas emerging from the annular gap at high speed can emerge directly in the region of the outlet edge and thereby reliably ensure that a liquid film is drawn out at the nozzle mouth to form a very thin liquid lamella, which is then divided into fine droplets.
  • the annular gap is formed between the outlet edge and an outer annular gap wall.
  • annular gap wall edge is formed by an annular gap wall edge and the annular gap wall edge is seen in the outflow direction after the trailing edge arranged.
  • the annular gap wall edge is arranged between 5% and 20% of the diameter of the outlet opening to the outlet edge.
  • the mixing chamber is at least partially surrounded by an annular chamber for supplying the compressed gas, and a gap air chamber connected upstream of the annular gap is in flow communication with the annular chamber.
  • the configuration of the two-component atomizing nozzle can then be simplified by removing the atomizing gas supplied to the annular gap from the annular space from which the mixing chamber is supplied with atomizing gas.
  • the flow connection is formed, for example, by means of bores in a partition wall between annular chamber and gap air chamber, which are suitable to be dimensioned in cross-section, also in relation to the bores forming a compressed gas inlet into the mixing chamber.
  • an outlet opening and the annular gap at least partially surrounding Schleierluftdüse is provided.
  • Schleierluftdüse leads to a further improvement of the spray pattern of the Zweistoffzerstäubungsdüse according to the invention, in particular, backflow vortex can be avoided by which drops and dust-containing gas are mixed together and lead to disturbing deposits on the nozzle mouth.
  • the veiling air nozzle has a veiling ring gap surrounding the outlet opening and the annular gap, the outlet area of which is much larger than the exit area of the annular gap.
  • the Schleierluftdüse is fed with compressed gas, the pressure of which is substantially lower than a pressure of the annular gap supplied compressed gas.
  • means are provided for imparting a twist about a central longitudinal axis of the nozzle to a mixture of compressed gas and liquid in the mixing chamber.
  • the compressed gas inlet has at least one first inlet bore opening into the mixing chamber, which is oriented tangentially to a circle about a central longitudinal axis of the nozzle in order to generate a twist in a first direction.
  • a swirl can be generated in the mixing chamber in a simple and less clog-sensitive manner.
  • a plurality of, in particular four, first inlet bores are provided in a first plane perpendicular to the central longitudinal axis and spaced apart in the circumferential direction.
  • At least one second inlet bore which is aligned tangentially to a circle about the central longitudinal axis of the nozzle to generate a twist in a second direction, is provided parallel to the central longitudinal axis of the first inlet bore.
  • a plurality of, in particular four, second inlet bores are provided in a second plane perpendicular to the central longitudinal axis and spaced apart in the circumferential direction.
  • At least three planes spaced apart parallel to the central longitudinal axis are provided with inlet bores, the inlet bores of successive planes generating an oppositely directed twist.
  • FIG. 2 shows a Zweowoffzerstäubungsdüse 30 according to the invention according to a first preferred embodiment.
  • the Zweistoffzäubäubdüse 30 according to the invention at least as regards the introduction of the liquid and the compressed gas into the mixing chamber and the shape of the nozzle subsequent to the mixing chamber, similar to the known nozzle according to Fig. 1 built up.
  • a liquid to be atomized is fed in the direction of an arrow 32 via an inner lance tube 34 running parallel to a central longitudinal axis 36 of the nozzle 30 and reaches a liquid inlet 38, which has a reduced cross-section with respect to the tube 34.
  • the liquid After passing through the liquid inlet 38, the liquid then passes in the form of a concentric to the central longitudinal axis 36 extending liquid jet in the cylindrical and concentric with the central longitudinal axis 36 arranged mixing chamber 40.
  • the tube 34 and the mixing chamber 40 are surrounded by an annular chamber 42, which through the gap between a outer lance tube 43 and the inner lance tube 34 is formed and in the direction of an arrow 44 pressurized gas, such as compressed air, is introduced.
  • a concentric with the central longitudinal axis 36 extending peripheral wall of the mixing chamber 40 has a plurality of inlet openings 46a, 46b, 46c, all together form a compressed gas inlet into the mixing chamber 40, so for supplying the so-called core air.
  • the compressed gas inlet openings 46 are arranged offset in the direction of the central longitudinal axis 36 as well as in the circumferential direction. As a result, compressed gas is introduced into the mixing chamber 40 in different layers. The exact arrangement of the compressed gas inlet openings 46 will be described below with reference to the Fig. 4 to 7 explained.
  • a frusto-conical constriction 48 is provided, which forms a convergent outlet part and which, after passing through a narrowest cross-section, again merges into a frusto-conical enlargement with a smaller opening angle, which forms a divergent outlet part.
  • the divergent exit part terminates at an exit opening 52 or a nozzle mouth.
  • the outlet opening 52 is formed by a peripheral outlet edge 54, which forms the downstream end of the outlet part.
  • the frustoconical constriction 48 and the frusto-conical extension 50 are surrounded by a funnel-like component 56, so that an annular gap air chamber 58 is formed between the funnel-like component 56 and an outer wall of the outlet part.
  • This annular gap air chamber 58 is supplied by means of a plurality of inlet bores 60 from the annular chamber 42 with compressed gas.
  • the lower end of the funnel-shaped component 56 is formed by an annular gap wall edge 62, which runs around the outlet opening 52. Between the annular gap wall edge 62 and the outlet edge 54, an annular gap 64 surrounding the outlet opening 52 is formed, which thus annularly surrounds the outlet opening 52.
  • annular gap 64 in the representation of the Fig. 2a shown enlarged again, compressed gas exits at high speed.
  • a liquid film 66 which forms on an inner wall of the conical enlargement 50, is drawn out at the exit opening 52 of this divergent nozzle exit part into a very thin liquid lamella 68, which disintegrates into small drops.
  • Experimental investigations by the inventors have shown that in this way the maximum droplet size of the two-component atomizing nozzle 30 in relation to the nozzle according to the prior art Fig. 1 same energy consumption can be reduced to about one third.
  • the annular gap air quantity is between 10% and 40% of the total atomizing air quantity.
  • the annular gap outlet edge 62 protrudes slightly in the flow direction with respect to the outlet edge 54.
  • the annular gap outlet edge 62 protrudes beyond the outlet edge 54 by 5% to 20% of the diameter of the outlet opening 52.
  • the annular gap air chamber 58 can be supplied with compressed gas from a separate line.
  • the holes 60 are closed and compressed gas is introduced from a separate line directly into the annular gap air chamber 58.
  • FIG. 3 shows another binary atomizing nozzle 70 according to a second preferred embodiment of the invention.
  • the two-component atomizing nozzle 70 with the exception of an additional Schleierluftdüse 72 is equal to the Zweistoffzäubungsdüse 30 of Fig. 2 so that on an in depth explanation of the basic operation is omitted and the same components are provided with the same reference numerals.
  • the funnel-shaped component 56 is surrounded in the two-component atomizing nozzle 70 by a further component 74, which is constructed in principle tubular, forms a further lance tube and narrows in the direction of the outlet opening 52 to a funnel-like.
  • a Schleierluftringspalt 76 is formed between the component 74 and the component 56.
  • the Schleierluftspalt 76 ends approximately at the height of the outlet opening 52 and a lower, circumferential edge of the component 74 is disposed at the same height as the annular gap wall edge 62.
  • a cross-sectional area of the Schleuf Kunststoffspalts formed thereby is significantly larger than the annular gap 64, so that avoided in the Schleierlufteintechnischtechnisch can be.

  • the thus twisted beam is centered thereby in the mixing chamber 40 and in the convergent outlet part and in the divergent outlet part of the nozzle 30, 70 automatically.
  • the tangential orientation of the compressed gas inlet openings 46a is based on the sectional view of Fig. 5 to recognize more precisely.
  • four holes in the plane I are uniformly spaced from each other in the circumferential direction, which form a flow connection of the annular chamber 42 in the mixing chamber 40.

  • the pressurized gas inlet ports 46c in the plane III are as Fig. 7 can be seen, again arranged equal to the compressed gas inlet openings 46a in the plane I, so that in the plane III again a flow around the central longitudinal axis 36 results in the counterclockwise direction.
  • the invention is therefore intended to impose counter-rotating swirl directions in the different planes I, II, III of the supply air bores.
  • the first inlet air bore plane I counted from the liquid inlet is left-handed
  • the second bore plane II is right-handed
  • the third bore plane is again left-handed. Due to the opposite directions of twist in the different planes I, II, III, strongly pronounced shear layers are produced in the mixing chamber 40, which contribute to the formation of particularly fine drops.
  • the two-component atomizing nozzles 30, 70 can be optimized in that the massive liquid jet entering the mixing chamber is split even before the interaction with the atomizing air. This can be done in a different, conventional manner, for example by providing impact plates, swirl inserts and the like.
