Definitions

  • the invention relates to a method for mixing diesel fuel with water to obtain a combustible emulsion, in which the amount of water to fuel falls in a range of 5 to 20 Vol%, wherein the fuel and the water are injected in a closed space in a ration falling in this range and are intensively moved to obtain a physical mix­ture.
  • the invention relates also to a diesel fuel water mixture comprising water in 5 to 20 Vol% compared to fuel, in which water drops are finely distributed in the fuel without the use of any emulsifier.
  • the invention relates to an apparatus for carrying out the method.
  • the second part of such solutions is related to the physical mixture of the two components without any emulsifier.
  • the main problem lies in that water and fuel cannot be mixed easily, and the water takes the form of small droplets in the mixture. Depending on the size of such droplets the beneficial effects of the water-fuel mixture can not prevail.
  • a further problem lies in that such phy­sically made mixture emulsions are not stable and water tends to separate from fuel after some time of storage.
  • a further problem of such mixtures is the expensive and energy-consuming way of their generation which often off-sets any advantage obtainable by the more perfect burning. It can be stated that physical mixtures of diesel fuel and water have not gained wide acceptance either.
  • the main object of the invention is to provide a comparatively stable and rea­dily utilisable fuel water mixture that can be used in diesel engines to improve efficiency and to reduce unwanted components of exhaust gases.
  • a further object of the invention is to provide a method for producing such a mixture.
  • a still further object of the invention is to provide an apparatus for carrying out the method.
  • the rotating fluid in the first vortex chamber is passed along a first axial direction and then is reflected so that the axial di­rection of movement is reversed.
  • the pressure of the recirculating fluid should be increased at least by 0.8 and at most by 3 bars by means of a pump in a path defined between the outlet of the second vortex chamber and the inlet of the first vortex chamber, and the feeding of water and fluid takes place in this path.
  • the lead-out mixture is passed to a fluid pump of a diesel engine having a return line which is fed back in the circulating loop at the suc­tion side of said pump.
  • the pressure prevailing in this suction side should be kept below 6 bars.
  • the pressure of the recirculating fluid is equalized in an equalization chamber before the fluid is passed in the first vortex chamber.
  • the mixing process will not be influenced by the lead-out of the mixture if the fluid is lead out of the second vortex chamber in a peripheral location where the outer diameter of the vortex is about in maximum.
  • a diesel fuel-water mixture comprising water in 5 to 20 Vol% compared to fuel, in which water drops are finely distributed in the fuel without the use of any emulsifier, in which the size of the droplets is smaller than about 200 nanometers and the physical con­sistency of the mixture is substantially identical with that of the fuel. It is pre­ferable if the amount of water is between 8 and 12 Vol%.
  • a recircula­ting loop is formed that comprises a pump, a vortex housing, a pressure equalizing chamber around the vortex housing connected to the pressure side of the pump, a first vortex chamber with an elongated ellipsoidal shape having a tapering neck portion and a longitudinal axis, a number of tangential inlet holes defined in the vortex housing along a periphery close to the neck portion, the axes of the inlet holes are inclined towards the end of the ellipsoid opposite to the neck portion, a tapering duct with a mouth substantially larger than and communicating with the opening of the neck portion, a second vortex chamber with an axis of rotation substantially normal to the axis of the first vortex chamber, the second vortex chamber has a spherical upper part, a hyperboloidal medium part tapering in downward direction, and a neck, the duct is leading tangentially in the second vortex chamber substantially at the equatorial plane
  • the pressure equalizing chamber has an annular shape encir­cling the vortex housing and each of the inlet holes comprises a countersink with an axis substantially normal to the mantle surface of the vortex housing and a jet portion with an axis inclining rearwardly and tangentially relative to the first vortex chamber.
  • the outflow opening is coupled to a fuel pump of a diesel engine provided by a return line which is fed back to the passage.
  • the upper part of the mixing apparatus comprises a first of main metal block 1, a second block 2 and a box-like third block 3.
  • the third block 3 is attached by means of threaded bolts through the second block to the right side of the first block 1 and the three blocks form a rigid mechanical unit.
  • the third block 3 has a large central cylindrical cavity 4 which has a spherical end with a circular nest hole 5 in the middle.
  • a vortex housing 6 is fixed in the cavity 4 by means of stud 7 fitted in the nest hole 5 and of a flange 8 fitting in a cylindrical recess of the second block 2.
  • the vortex housing 6 is an elongated symmetrical element with a horizontal axis 9 of rotation.
  • the outer contour line of the vortex housing 6 is curved in axial direction to substantially correspond to the shape of the cavity 4, whereby an annular pressure chamber is formed around the vortex housing 6.
  • An ellipsoi­dal vortex chamber 10 is defined in the vortex housing 6 with a tapering neck portion 11 made in the second block 2.
  • the profile of the neck portion 11 has an inflexion plane and a mouth opening 12 at the left face of the block 2.
  • eight evenly distribu­ted inlet holes 13 are provided in the wall of the vortex housing 6 (Fig. 3).
  • Every inlet hole 13 comprises a jet portion 14 with an axis slightly inclined in axial direction towards the dead end of the ellipsoid and a countersink 15 communicating with the associated jet portion 14.
  • the angle of axial inclination is about 15 - 20°.
  • Fig. 3 shows the axis of the jet portions 14 are inclined also in the plane normal to the axis 9 and the angle of inclination relative to the corresponding radius is about 15°.
  • the countersinks 15 have axes substan­tially normal to the mantle surface of the vortex housing 6.
  • the first block 1 defines a second vortex chamber 16 which has a balloon-like shape with a vertical axis 17 of rotation.
  • the second vortex chamber 16 has a substantially spherical upper part 18, a downwardly tapering medium part 19 which has a shape of a rotational hyperboloid and a short cylindrical neck 20.
  • Outflow opening 21 is defined at the equatorial plane of the spherical upper part 18 with an axis in line with the axis 9 of the first vortex chamber 10.
  • the outflow opening 21 leads to the left side wall 22 of the first block, and an end of an outflow pipe (not shown in the drawings) can be fitted therein.
  • An air dis­charge hole 22 is made in the upper wall of the first block that enables deaera­tion of the second vortex chamber.
  • a fur­ ther air discharge hole 23 is provided for the deaeration of the cavity 4.
  • An oblique conical duct 24 is provided in the first block 1 extending between the mouth opening 12 of the first vortex chamber 10 and the second vortex chamber 16.
  • Fig. 4 shows that the duct 24 has an axis 25 enclosing an angle of about 20° with the horizontal axis 26 of the second vortex chamber 16 defined in the equatorial plane.
  • the cone angle of the inwardly tapering duct 24 is also about 20°.
  • the outer mouth 27 of the duct has a diameter substantially larger than that of the mouth opening 12 of the first vortex chamber 10 which latter opening 12 is arranged concentrically in the centre zone of the mouth 27.
  • the duct 24 provides a quasi-tangential passage between the two vortex chambers 10 and 16.
  • Fig. 2 shows the lower part of the apparatus of fig. 1.
  • a vertical cylinder bore 30 is formed in the first block 1.
  • the bore 30 is open at the bottom in which a re­turn line can be connected for unused (excess) fuel-water mixture.
  • An inflow bore 31 is arranged in the first block 1 that communicates with the bore 30.
  • the inflow bore 31 has a pipe connection to which a feeder pipe for pre-mixed diesel fuel and water can be connected. Such a mixture can be supplied by a feeder pump e.g. like the one shown in fig. 5.
  • a pump motor 32 is mounted to the third block 3 that has a horizontal shaft 33 inserted in and sealed from a bore of the second block 2.
  • a pump wheel 34 is mounted on the inner end of the shaft 32.
  • a cylindrical cavity 35 is provided between the first and second blocks 1 and 2, in which the wheel 34 is arranged. In front of the central portion of the wheel 34 the cavity 35 communicates with a widening of the vertical bore 30.
  • a horizon­tal channel 36 is provided in the second and third blocks 2, 3 that leads to the annular cavity 4 around the vortex housing 6.
  • Pre-mixed diesel fuel and water is supplied to the system via the inflow bore 31. Before normal operation begins, the air in the cavities should be removed. This can be done through the two air discharge holes 22, 23. Let us suppose that no return line is connected to the lower end of the vertical bore 30 and it is closed temporarily.
  • the pump motor 32 is started and the pump starts to circulate the mixture in a closed loop.
  • the suction side of the pump wheel 34 is at the vertical bore 30, while the pressure side is at the channel 36.
  • the pump provides a flow of 1500 l/h and the pressure dif­ference between the two sides of the wheel 34 is about 1 to 3 bar, preferably between 1 and 1.8 bar.
  • the liquid will fill the annular cavity 4 around the vortex housing 6 and an intensive flow takes place through the tangential jet portions 14 of the inlet holes 13.
  • the comparatively large cavity 4 serves as a pressure equalizer.
  • a vortex is created therein which can be characterized by spiral arrow 37 indicated in the first vortex chamber 10.
  • the peripheral zone of the rotating liquid streams towards the dead end of the ellipsoidal space, and from here it will be reflected in forward direction to­wards the tapering neck portion 11 in the central zone around the axis 9. In this central zone an intensive rotation takes place around the axis 9, the pressure increases and it reaches a maximum at the zone of the mouth opening 12.
  • diesel fuel has a certain degree of compressibi­lity, i.e. the volume thereof slightly varies with the pressure. Compared to the fact water has practically no compressibility at all, the pressure of the rotating mixture will drop suddenly after the liquid leaves the mouth opening 12 and enters the duct 24 that tapers in forward direction, since the cross-section of the duct is substantially larger than that of the opening 12.
  • the volume of the fuel increases to an extent, while the volume of the water remains unchanged. This flexible volume increase during rotation might contribute to certain extent to the resulting very fine mixture of fuel and water.
  • the pressure will increase towards the end of the tapering duct again and the liquid is injected tangentially into the second vortex chamber 16 at the equatorial plane thereof.
  • a double vortex will be formed in this chamber, since the injected liquid rota­tes around its axis of flow, and owing to the specific form of the second vortex chamber 16 and to the tangential inlet, a rotation around the vertical axis 17 takes also place.
  • the sucking effect of the pump results in a vertical flow of the rotating liquid.
  • the tapering form of the vortex chamber maintains the rotation and increases its speed in the proximity of the vertical axis 17.
  • the speed distribution will be similar to the funnel of a tornado.
  • the mixture will be sucked in by the pump again and in the next cycle this pro­cess is repeated.
  • the recirculated mixture of the fuel and water will be more and more evenly distributed i.e. the size of the water droplets effectively de­creases and by the end of about the tenth cycle such a fine mixture is obtai­ned, in which the consistency of the mixture cannot be distinguished from that of the fuel.
  • the place from where the liquid can be lead out is rather critical.
  • the liquid outflow should not disturb the turbulence distribution in the two vortex cham­bers and in the connecting passage.
  • An optimum place is the equatorial plane of the second vortex chamber 16 where the outflow opening 21 has been provided.
  • a preferable use of the apparatus is the insertion thereof in the fuel feed line of a diesel engine.
  • the outflow opening 21 should be connected to the fuel inlet of the fuel pump. Since the outflow rate of the emulsion genera­ted by the apparatus according to the invention is relatively stable and the fuel consumption of the diesel engine is fluctuating, the surplus quantity is returned by the fuel pump.
  • the return line is connected to the lower end of the vertical bore 30, which now must be open. The return of the excess amount of emulsion in the circulating flow further improves the consistency of the emulsion.
  • the fine mixing results are largely independent form the absolute pressure va­lues in the system.
  • the absolute value of the pressure prevailing in the bore 30 (at the suction side of the pump) can be as high as 5 bar. It has been experien­ced that the quality of the emulsion has decreased when the pressure was in­creased above 6 bar.
  • the pressure difference provided by the pump is more cri­tical. A pressure increase of 1 to 1.5 bar can be optimum with dimensions shown in the drawings. This difference can be as high as 3 bars.
  • the size and constructional design of the apparatus allows a large tolerance range regarding both the absolute and relative pressure values.
  • the propotion of water to fuel in the mixture can be varied within a wide range. In normal diesel engines, however, the increase of water quantity above 20% start to remarkably reduce the effective power of the motor. It is true that the amount of unwanted components in the exhaust gas will be reduced more effectively.
  • the optimum percentage of water to fuel is between about 8% to 12% and the range between 5% to 8% and 12% to 20% is still preferable. Values below or above these limits can be acceptable, however, they cannot provide the benefits connected with the preferable ranges. Under 5% water con­tent the improvement of the composition of the exhaust gases is not as signifi­cant to make the use of the apparatus profitable. The problem of efficiency over 20% water in the mixture has already been discussed.
  • FIG. 5 A preferable embodiment of a mixing pump which can provide a mixture of wa­ter and fuel with predetermined ratio is shown in Fig. 5.
  • the pump has a cylin­drical sleeve 4a in which a shaft 41 is guided by ball bearings 42, 43 for rota­tion.
  • the shaft 41 has a wider head 44 with an inclined face which supports a thrust bearing 45.
  • a piston block 46 is attached to the end of the sleeve 40 which comprises a pressure chamber 47 for water and a pressure chamber 48 for fuel. The size of the two chambers is different.
  • Respective pistons 49 are guided in the piston block 46 for axial movements.
  • One end of each piston is pressed to the thrust bearing 45 by means of respective coil springs 51, 52 in the associated chambers.
  • a water inlet 53 leads through the side wall of the block to the water chamber 47 and a fuel inlet 54 to the fuel chamber.
  • Respec­tive outlets are provided through the end walls of the chambers 47, 48 in which respective ball check valves are arranged to prevent reverse flow.
  • the inlets 53, 54 comprises similar check valves.
  • the outlet sides of the two outlets are coupled to a common channel 55 from which outlet 56 of the mixing pump is branched off.
  • a Zeiss high power light microscope was used with differential interference contrast according to Normanski.
  • the samples were analyzed by a planechroma­tic oil immersion objective with 100-fold magnification which has a numerical aperture of 1.32.
  • a 6.3-fold large field ocular was used and a 1.25-fold magnifi­cation selector was employed. From these data a magnification of 787.5-fold is obtained at the ocular and a full magnification was 1250-fold high.
  • the resolu­tion of this microscope was as high as to be able to differentiate structural elements with as small distances as 132 nanometer.
  • Samples from diesel fuel and water mixture produced freshly by the apparatus according to the invention (with 10:1 ration of fuel to water) were taken by a pipette of 4 microliter, these were put on a glass plate covered by another glass plate and sealed by nail polish. The analysis took place without delay.
  • Fig. 6 right upper and left lower sides are the graphical representation of the pictures obtained form the mixture according to the invention and the pure fuel as a) hereinabove.
  • the elongated spot visible on both pictures was deliberately a size gauge.
  • Fig. 7 shows the emulsions with fuel water ratios of 10:1 and 50:50 respective­ly. The pictures show clearly the water drops in front of the homogene fuel background.
