Definitions
- the invention relates to a method and a device for atomising liquids with the help of of gas streams and the use of such Contraption.
- a uniform atomization is in addition to the internal combustion engines, like petrol engines in two-stroke or Four-stroke or diesel engines also for other internal combustion engines, like gas turbines and others Force from burns producing apparatus, such as Thrust engines with their combustion chambers and also for Boiler and the like desirable.
- the fuels are thereby liquid fuels and in the Gases for combustion are usually air, which they are referred to below, even if it is not just air, but also to aid their mixing with the combustion Gases acts.
- the invention is therefore based on the object Method and device for atomizing To create liquids by means of gas streams with which the liquid in as fine a droplet achieved in close and / or controlled distribution become.
- This particular, meanwhile also referred to as Nanoval method has principle in the atomization of molten metal as advantageous proved (DE 33 11 343), by fine particles arise in close distribution and become good spherical form as a powder.
- the inventive Atomization is from the mass flows of both media gas and liquid and the surface tension and viscosity of the liquid substantially certainly. These are gas flows in the range of the speed of sound up into the supersonic, ie in air currents and over 300 m / s.
- the gas flow around the liquid jet is laminar and is constantly accelerated. This is served by the injector, rather something below her arranged Lavaldüse of convergent divergent Cross-section.
- the Beam diameter increases in its interior the pressure against the external surface tension.
- the gas is accelerated, the pressure in it decreases and there is a bursting of the liquid jet, if the surface forces do not hit the beam can hold together more. This is done as a license plate of the process abruptly and approximately in the area the narrowest cross-section of the Laval nozzle or in Running direction afterwards.
- the liquid droplets spread to the side, because the sudden bursting superimposed as a result of the predominant internal pressure the forward momentum of the liquid jet.
- the mixture formation is improved in the atomization of fuel oils in burners increases the efficiency and reduces the harmfulness of the exhaust gases, in atomizing nozzles for colors, finishes, humidification - here by the laminar type of atomization low noise - And also the advantage of finer particles used in close distribution.
- the droplet size does not vary so much in particular, no too large droplets are generated, if not, as with diesel engines sometimes at different ranges when filling the Combustion chamber is desired, and the entire Combustion chamber is evenly filled by the mixture.
- the expansion of the from air and liquid formed by mixture Expansion at one corner the so-called Prandtl-Meyer-Strömung, be used after which a supersonic flow at one corner in the following Space is expanding, in strong widening until over 90 ° to the original flow direction. Prerequisite is a supersonic flow before and a further expansion opportunity by one after the corner following deeper pressure.
- the invention makes the possibility of sudden expansion use a supersonic jet. Due to the dilution and shockwaves can be the mixing of Liquid, e.g. Fuel and air are improved.
- Essential in the inventive method and the device, in particular for use in the Automotive sector, is the mixture production through an accompanying air flow, which is a part, but also represents the entire combustion air.
- a pure air flow into the cylinder be blown at the same time for flushing the combustion chamber is used, and the fuel jet then introduced into the existing airflow
- air and fuel can, too to stream at the same time.
- the parallel flow between Gas and liquid keeps the liquid jet up to the Aufplatztician together, and indeed longer than this happens in other sputtering processes.
- the pressure atomization is lower than in the prior art the pressure atomization.
- the apparatus and method of the invention are designed to burst into both Media, gas and liquid, laminar flow is present.
- This is basically the invention accelerated gas flow, while a delayed Flow as in injecting into still air one Subject to destabilization and fanned turbulence becomes.
- it comes only after the bursting in or after the passage of sound to shock waves and dilution waves and then also to turbulence. But since the droplets are already formed. Both, supersonic shock waves and turbulence, promotes the mixing of laminar Droplets with the air, in the case of internal combustion engines the fuel droplet with the Combustion air.
- the two-substance atomizing device according to the invention can also reduce exhaust gas pollutants, detached from the combustion process, then afterwards be used on it, as it is with partial load Exhaust gas recirculation or with separate treatment of the mixture, e.g. with urea, happens.
- a Device for atomizing according to the invention shown, in the present case, the device for use in the automotive sector as an injection device is described.
- the injection or Atomizing device has a housing 1, a first part 2 with a liquid or Fuel channel 4 forming through hole and an annulus 10 includes.
- the liquid or Fuel channel 4 is connected to a not shown Fluid or fuel supply connected, while a manifold connected to the annulus 10 9 to a gas or air source, not shown connected.
- a lower one Part 3 of the housing provided, in which to a Zerstäubungsraum open a Laval nozzle 5 is formed.
- the upper part 2 is inserted in the lower part and centered that between them an annular gap channel 6 is formed, which communicates with the annular space 10 in connection stands. Furthermore, the fuel channel 4 opens into a capillary 14, which in turn is in the area of closest cross-section 12 of the Laval nozzle 5 optionally also something below ends.
- the device according to Figures 1a and 1b is e.g. on a suction pipe of the engine or directly on the cylinder head or attached to the combustion chamber of a gas turbine.
- These are basically small Dimensions.
- the flow cross section of the liquid channel 4 in the upper part only in the millimeter range and the outlet 15 of the capillary 14, depending on the engine power or cylinder, for the mixture is prepared, in tenths of a millimeter range, and accordingly, the inner diameter for the annular gap channel 6, which is the lower Area 11 tapers, just a few millimeters.
- the liquid fuel is according to the arrow 7 introduced into the fluid channel 4, while the Air flows along the arrows 8 in the manifold 9 and from there distributed in the annulus 10 and flows into the annular gap channel 6.
- Im rejuvenating lower area 11 decreases the air speed steadily until they are in the narrowest 12 of the Laval nozzle 5 passes.
- Will the critical pressure ratio exceeded, so here is speed of sound, but never again.
- the described strong expansion on a corner can to an extension of the Laval nozzle 5 after the narrowest cross section, also by taking back the contour connect, leaving a corner or even a return is formed, which is a sudden spread of the liquid-gaseous medium allowed. requirement is a supersonic flow previously.
- On short ways can be characterized by a strong spread of the mixture, as generally desired.
- the distraction is stronger, the larger the Supersonic speed in the extended part of the Laval nozzle 5 is, i. the higher the Mach number that the Ratio of the velocity at the outlet of the Laval nozzle to the speed of sound in the narrowest cross-section represents the Laval nozzle.
- Atomizing air can be used, be it that it is is a continuous atomization of the fuel, as in gas turbines or intermittently, as in most cases with gasoline and diesel engines.
- Atomizing air can be used for mixture formation in one Cylinder the previously achieved higher pressures of another can be used and stored in storage tanks compressed air from cylinders over opening and closing valves are fed.
- Methods are known and used e.g. in the US 2 134 786 or DE 37 32 259.
- Fig. 3 is another embodiment of Invention shown schematically, which is here is the working cycle of a two-stroke engine. This is a measure in which with the atomization by means of enveloping combustion air jets higher Speeds the engine power at given Effort can be increased.
- this embodiment becomes a clock-controlled injection nozzle 20 according to the device according to the invention used, which opens into a cylinder chamber 22. Of the Cylinder also has an exhaust valve 21 on.
- injection nozzle 20th initially only air has flowed into the cylinder chamber, the evacuation of the cylinder chamber 22 of fuel gases supported. The exhaust gases and additional air from the nozzle 20 leave the upward thrust of the piston 23 over the valve 21 the cylinder chamber 22.
- the atomizing nozzle can also by Blowing up and down obliquely Perform exhaust better.
- the pressures are known much higher than the petrol engine and should one Injection nozzle according to the device according to the invention used, it must be designed for these pressures to meet the demand for auto-ignition or it must have an additional ignition, for example done by spark plug.
- FIGS. 4 and 5 show results in the atomization of water with air by means of the device according to the invention.
- the Sauter diameter d 3.2 is used as a measure of the droplet size, the droplets in spherical form - which they are in a very good approximation with not too high viscosity of the liquid and the generally high surface tension - are assumed.
- the Sauter diameter d 3.2 was measured by a Malvern device, the liquid was water and air was used as the sputtering gas.
- the ordinate has the Sauter diameter on the right for n-heptane, which is the model liquid for atomizing nozzles in the area of Internal combustion engines is. This may be from the for water be estimated.
- FIG. 5 shows the gas consumption V G in standard cubic meters of air per kg of water as a function of the required compression energy P G in watts for the atomizing air.
- the individual characters of the diagram represent the measured values for the Sauter diameter for water. In achieving smaller droplet diameters, given by the squares in the diagram, the values fluctuate more, due to geometric changes in the liquid nozzle and the Laval nozzle and their association with each other.
- the diagram is intended to represent the basic conditions of this type of atomization and approximately achievable values.
- the values for n-heptane can be estimated, for example as follows: water n-heptane ⁇ ⁇ 31 ⁇ m ⁇ 20 ⁇ m ⁇ 31 ... 39 ⁇ m 20 ... 25 ⁇ m ⁇ > 39 ⁇ m > 25 ⁇ m
