Definitions

  • the present invention relates to a method and an apparatus for producing a water-in-oil emulsion.
  • emulsifiers i.e. chemical additives which are used to produce at least briefly stable emulsions, i.e. homogeneous mixing of two immiscible substances, e.g. a water-oil liquid can be used.
  • emulsifiers i.e. chemical additives
  • the aim of the present invention was to create a method or a device which, especially for use in motor vehicles, reliably and simply processes a water-in-oil emulsion as a fuel for diesel engines.
  • the addition of water to fuels leads to lower fuel consumption, reduced pollutants or an increase in the performance of internal combustion engines.
  • the water is introduced into the cylinder chamber via a separate injection system, where it mixes with the injected fuel shortly before combustion.
  • Chemical emulsifiers are not suitable for use in internal combustion engines because of the generation of additional pollutants.
  • Conventional mechanical devices for achieving water-in-oil emulsions have the disadvantage, however, that with the small flow rates required, for example for light vehicle diesel engines, a constant mixing ratio is not achieved, but this must be required for sensible operation.
  • the process according to the invention is characterized in that, in order to achieve a predetermined water / oil quantity ratio from a water and a separate oil supply, the required amounts of water and oil are dispensed and these quantities are then combined so that the mixture is used to produce the emulsion a mixing chamber with a funnel-shaped outlet is conveyed, and the emulsion produced is conveyed from the mixing chamber into a storage chamber and is kept in constant motion there, a portion of the emulsion being withdrawn from the storage chamber and, if necessary, again with a new mixture into the mixing chamber and thus into a closed circuit is promoted, while another portion of the emulsion is removed from the storage chamber and fed to the consumer.
  • a dosing device to achieve a predetermined water / oil ratio, a mixing chamber with at least one tangential inlet and an axial, constricting outlet, a connecting line between the dosing direction and the mixing chamber in which the metered amounts of water and oil are brought together and into which conveying means are installed, further through a storage chamber connected to the outlet of the mixing chamber, the connecting line between these chambers also leading approximately tangentially into the storage chamber, and that the latter has an outlet leading to the suction side of the conveying means and an outlet leading to the consumer of the emulsion.
  • the metering device with membrane walls and electromagnetic lifting drive has proven to be particularly advantageous for use in vehicle engines. It is suitable to achieve a constant water-oil ratio in the constantly changing operating conditions. At the same time, the device has a particularly advantageous emergency running property in that, even when the power supply to the linear actuator is interrupted, diesel oil is available for motor operation by appropriate dimensioning of the check valves and the magnet in the lines.
  • the conveying means for generating a constant closed circuit in the device may only accelerate the liquid or its components gently, as is achieved, for example, by curved delivery blades of a low-pressure centrifugal pump.
  • the mixing chamber is preferably hemispherical with two concentric chambers, the inner chamber opening into a funnel-shaped part where the emulsion is accelerated and also the swirl which it has received through the tangential feed into the outer chamber is increased and the Mixing promotes.
  • the channel narrowing in the shape of a funnel preferably opens into an approximately cylindrical expansion channel, thereby increasing the mixing.
  • This expansion channel finally opens, again narrowing at the end, into a storage container.
  • the emulsion In the storage container, the emulsion is kept in constant motion by means of a tangential inlet, so that it does not separate and remains stable.
  • the storage container has a connecting channel to the suction side of the conveying means, so that a closed circuit is constantly maintained in the device, as long as the conveying means are in operation.
  • the storage container also has a removal line for supplying the emulsion to the consumer, for example to the injection pump of a diesel engine.
  • This connection is preferably approximately in the same cross-sectional plane in the storage container as the inlet from the mixing chamber.
  • a hemispherical part of the storage container with a ventilation opening in the zenith has proven to be ideal.
  • a water-to-oil ratio of about 1:10 has proven to be particularly advantageous for use in vehicle engines. Pollutants such as soot, nitrogen oxides and carbon dioxide are significantly reduced compared to operating with diesel oil alone.
  • the use of the device according to the invention for producing a water-in-oil emulsion provides, for example to combustion engines or oil burners, an emulsion which is essentially stable and constant in relation to water-oil, even under constantly changing operating conditions, which contributes very greatly to reducing pollutant emissions.
  • Fig. 1 of the drawing the structure of a device according to the invention is shown, the arrows respectively the direction of flow of the emulsion or. of water and oil.
  • the water line 10 and the oil line 11 lead into the metering device 1, after which the precisely metered amounts of these liquids are brought together in the collecting line 12 via the outlet lines 10 Samm and 11 ⁇ and reach the suction side of a conveying pump, here a centrifugal pump 2.
  • the mixture accelerated by the pump 2 reaches the mixing chamber 3 via the feed line 28.
  • the mixing chamber 3 is divided into an outer chamber 3 ⁇ , into which the feed line 28 opens tangentially, and an inner chamber 3 ⁇ .
  • the partition of the two chambers 3 ⁇ , 3 ⁇ has circular recesses 6 which are chamfered approximately parallel to the direction of flow. This arrangement makes a particularly advantageous mixture reached the water-oil mixture and created a water-in-oil emulsion. Because the leading part 3 ′′′ of the mixing chamber 3 is tapered, the swirling and mixing of the water and oil particles is intensified. Finally, the vessel part 3 ′′′, expanding suddenly, opens into an expansion channel 7 before the emulsion finally reaches the storage container 5. The tangential feed into the storage container 5 ensures that the emulsion in the storage container 5 remains in constant motion (vortex). In order to remove the air in the device during the first filling process, the storage container 5 has a ventilation opening 7 at its highest point.
  • the removal opening or line 8 which leads to the injection pump when used in diesel engines, for example, is preferably located at the same height as the storage container 5 like its tangential feed line of the expansion channel 4. So that an ideal emulsion is always available in the storage container 5, a circuit of the emulsion is constantly maintained in the device itself by the storage container 5 having a return channel 5 'to the conveying means 2 at the lower end.
  • the structure of the metering device 1 can be seen in more detail in FIG. 2 of the drawing.
  • the metering device 1 has a pump chamber 14 for water and a larger chamber 15 for oil in accordance with the desired water-oil ratio.
  • the discharge line 12 are check valves 13 attached.
  • the membrane walls 16, 17 are coupled to one another via a fixed actuating rod 18 and are preferably connected to an electromagnetic drive (not shown) which drives the membranes in an oscillating manner.
  • the dimensions of the pump chambers 14, 15 and the membrane surfaces 16, 17 each lead water and oil into the line 12 in a specific, constant ratio.
  • the flow rate can be varied either by the frequency of the membrane movement or by different strokes. Since the stroke is not rigid due to an electromagnetic drive, but depends on the back pressure, no special control of the flow rate through the metering device is necessary. With appropriate dimensioning of the solenoid, a small pressure build-up in line 12 is sufficient, e.g. if little or no emulsion is removed from the storage container 5 so that the corresponding check valves 13 remain closed. If a large amount of emulsion is required, a low pressure in the line 12 causes a small back pressure in the chambers 14, 15 and the solenoid reaches a large stroke with a correspondingly large flow rate.
  • Another great advantage is the emergency running property of the metering device, in that if the diaphragm 16, 17 has a defective drive, the water supply line 10 is closed by the check valve 13 of this line (if the valve has a correspondingly dimensioned spring which exerts a greater pressure than the pressure in the water supply).
  • the oil supply via line 11 is preferably carried out by means of a pump, whereby a sufficiently large pressure can be achieved to both valves in line 11, respectively. keep the line 11 ⁇ open and thus supply the device with oil. This ensures problem-free operation of, for example, a diesel engine with diesel oil alone.
  • FIG. 3 A connection diagram of the entire device 19 to a vehicle diesel engine 26 is shown in FIG. 3.
  • the water tank 21 should be mounted somewhat higher than the connection on the device 19, while the oil tank 20 can be arranged as desired since an intermediate feed pump 22 is provided.
  • the removal line 23 from the reservoir 5 in the device 19 leads to the injection pump 24. From there, the emulsion reaches the combustion chamber of the diesel engine 26 via the injection nozzles 25.
  • the leakage lines 27, 27 ′ are coupled to the return connection 9 (FIG. 1) of the device 19.
