Definitions
- a liquid is introduced parallel to a central longitudinal axis 24 in the direction of arrow 1.
- the fluid is concentric with the central longitudinal axis 24 extending lance tube 2 out and enters a liquid inlet 10 in a mixing chamber 7 a.
- 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.
- 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.
- 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 Zweistoffzerstäubungsdüse be provided, in which a uniformly fine droplet spectrum can be achieved both in the edge region and in the jet core.
- 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 in terms of the required construction volume of evaporative coolers or of sorption systems, eg for the flue gas cleaning. 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.
- 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 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 arranged in the outflow direction after the trailing edge.
- the annular gap wall edge is arranged between 5% and 20% of the diameter of the outlet opening to the outlet edge.
- control means and / or at least two compressed gas sources are provided, so that a pressure of the compressed gas supplied to the annular gap and a pressure of the compressed gas opening into the mixing chamber through the compressed gas inlet can be set independently of one another.
- Separate pipes for pressurizing the mixing chamber and for pressurizing the annular gap with compressed gas offer advantages in that the pressure in a gap air chamber upstream of the annular gap is then independent of the pressure of the atomizing gas, which is supplied to the mixing chamber, can be specified. This is then in view of the own energy requirement of importance when compressors with different back pressure or steam networks with matching different pressures in a system are available. In general, however, only a compressed gas network with a single pressure will be available. In this case, for example, pressure reducers can be used.
- the annular gap air volume is adjusted via separate valves, regardless of the core jet air quantity, which is introduced into the mixing 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 void air ring gap surrounding the outlet opening and the annular gap, whose outlet area is much larger than an 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.
- 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.
- 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, 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.
- 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.
- 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 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 in the Schleierlufteintechnischtechnisch, can be.
- the nozzle nozzle or the outlet opening 52 annularly enclosing Schleierluftdüse 72 can be energetically charged with low pressure air, which is supplied according to an arrow 78.
- the two-component atomizing nozzle 30 and the two-component atomizing nozzle 70 of the Fig. 2 or 3 can be arranged at the lower end of a so-called sputtering lance, which projects into a process space.
- FIG. 4 shows a sectional sectional view of the two-component atomizing nozzle 30 of Fig. 2 .
- sectional planes which are designated I, II and III.
- the bores for forming the compressed gas inlet openings 46a, 46b, 46c are each aligned tangentially to a circle around the central longitudinal axis 36 of the nozzle.
- 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. All of these bores are arranged tangentially to an imaginary circle 80 about the central longitudinal axis 36 of the nozzle.
- an imaginary circle 80 about the central longitudinal axis 36 of the nozzle.
- the presentation of the Fig. 6 shows the arrangement of four holes to form the Druckgaseinlassö réelleen 46 b in the plane II.
- the Druckgaseinlouö réelleen 46 b are also arranged tangentially to a circle about the central longitudinal axis 36 of the nozzle, but such that in the plane II, a flow about the central longitudinal axis 36 in the clockwise direction results.
- 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.
