Description

[Technical field]

[0001] The present invention relates to a method and an apparatus for producing a water-containing fuel. [Background technology]

[0002] Traditionally, emulsion fuels, which are fuel oil mixed with water, have been produced to reduce fuel costs and pollutant emissions. The water content of these fuels is about 10% to 18%, so they do not contribute much to reducing fuel consumption or pollutant emissions, and the water content lowers the combustion temperature. In addition, it is expensive to improve the equipment for adjusting the air from outside, so they are not very popular. The method described in Patent Document 1 is easy to use because it blends C heavy oil with water very well, is not affected by temperature differences, and does not become tarry. However, when light fuels such as diesel are treated in the same way, it is difficult to stably contain water. According to the method described in Patent Document 2, the obtained water-containing fuel is stable, but the period until the oil-water separation phenomenon occurs is short, and the oil-water separation phenomenon may occur after 2 to 3 months. In addition, the transparency of the water-containing fuel using diesel fuel etc. is lower than that of the base oil. In addition, the insertion of enzymes such as catalase as an additive causes a problem of high cost. According to the method described in Patent Document 3, water-containing fuel still causes oil-water separation. In addition, the extent to which the energy generation efficiency decreases by adding water has not been fully verified. [Prior art documents] [Patent documents]

[0008] The method and device for producing water-containing fuel according to the present invention will be described. The method and device for producing water-containing fuel, the overall configuration, values, liquid flow direction and conditions, etc. shown in this specification are not limited to the embodiments and examples described below, and may be modified within the range of shapes, combinations, volumes, dimensions, etc. that can achieve the same effects within the technical concept of the present invention. The following description will be made with reference to the attached drawings. The method of the present invention includes a water reforming step and a mixing step of the obtained water and fuel. The apparatus also includes two types of apparatus: an apparatus for water reforming and an apparatus for mixing the obtained water and fuel. In this specification, the ultrasonic oscillators, spiral tube type mixers, and the like in each step and each device may be of the same structure or may be of different structures between each step and each device. The manganese-containing layer in this specification may be any layer containing metallic manganese and / or a manganese compound, and among them, manganese dioxide, todorokilite, manganese blende, rhodochrosite, hausmannite, pyrolusite, tephroite, rhodonite, braunite, and the like can be used.

[0009] The process for obtaining the water-containing fuel of the present invention is outlined in FIGS. In step A, water, which is one of the raw materials for water-containing fuel, is supplied to an ultrasonic water reforming treatment device 1 for treatment. In step B, the treated water is supplied to a heater device 2 equipped with a tube having a heater and heated in the tube. In step C, the heated water is passed through a tube equipped with an ultrasonic oscillator, a ceramic layer, and a spiral tube-type mixer (ultrasonic oscillator + ceramic layer + spiral tube-type mixer 3) for treatment. In step D, the treated water is passed through a device 4 containing a manganese-containing layer on its inner surface to obtain treated water. The water obtained in step D is stored in a reformed water storage tank 5 as necessary.

[0010] The water and base oil obtained through steps A to D are passed through an ultrasonic mixed oil reforming device 6 in step E to obtain a mixed oil. The obtained mixed oil is treated in a mixer 7 equipped with an ultrasonic oscillator and a spiral tube in step F. The obtained mixed oil is passed through a spiral tube mixer 8 equipped with an ultrasonic oscillator (ultrasonic oscillator + spiral tube mixer) in step G to further mix and obtain a water-containing fuel. The water-containing fuel obtained in step G is temporarily stored in a reformed oil secondary storage tank 9 and a reformed oil primary storage tank 10 as necessary, and shipped as a product. The devices for carrying out the above steps A to G are referred to as device A to device G, respectively.

[0011] [water] The water used in the present invention may be fresh water such as industrial water, household tap water, well water, river water, etc. However, considering that the water is supplied to an internal combustion engine as a water-containing fuel, it is preferable that the water has a low salt content.

[0012] [Base oil] In the present invention, the base oil before being mixed with water may be fuel oil such as light oil, heavy oil, kerosene, gasoline, aviation fuel, naphtha, etc. Edible oil or vegetable oil that cannot be used for food, such as palm stearin oil, jatropha oil, bongamia oil, used edible oil, biodiesel oil, etc. may also be used.

[0013] [Items common to all devices used in the present invention] Each device used in the present invention must be made of a material that does not corrode or deteriorate, especially in the parts that come into contact with water or base oil. For example, stainless steel, copper alloys, silicon, magnesium, or aluminum alloys that are easy to process and contain manganese, ruthenium, niobium, etc. may be used. If corrosion or deterioration occurs, the resulting water-containing fuel will contain impurities such as metals, metal compounds, and ionic substances derived from the components of the device, which may contaminate the inner surfaces of internal combustion engines that burn the water-containing fuel. In addition, before or after each of the steps A to G, or before or after each of the devices A to G, other steps or devices related to the present invention may be provided as necessary. Furthermore, a plurality of the same steps or devices may be provided in series, or a plurality of the same steps or devices may be provided in parallel. By employing each of the steps A to G, or each of the devices A to G, the present invention can obtain a stable water-containing fuel. If some of the steps or devices are missing, the effects of the present invention cannot be obtained. The water obtained after carrying out steps A, B, C, and D in this order may be returned to the initial step A and processed again in this order. Such processing from step A to step B may be repeated multiple times. The order of processing by steps C and D may be changed, and step C may be carried out immediately after step D. It should be noted that step B may or may not be performed, and in this sense step B is optional. In addition, the mixture of water and base oil obtained after carrying out steps E, F, and G in this order may be returned to the initial step E and treated again in this order. The treatment from step E to step G may be repeated multiple times.

[0014] <Process A and Equipment A> Step A and device A in the present invention are a step and device for treating water using an ultrasonic water modification device (ultrasonic resonance type water modification device) 1. FIG. 3 shows the ultrasonic water modification device 1. The ultrasonic water modifying treatment device 1 preferably includes a spiral ultrasonic oscillator 11 and / or a horn ultrasonic oscillator 12 provided in the internal water flow path. The helical ultrasonic oscillator 11 has a structure in which a cylindrical member (horn) having a helical uneven surface on its side is connected to an ultrasonic transducer. This helical ultrasonic oscillator 11 is preferable in that it is a device that can effectively treat fluids by ultrasonically vibrating not only the cylindrical member, but also the helical projections and recesses, or the base on which the cylindrical member is provided. Horn-type ultrasonic oscillator 12 has a structure in which a long member (horn) with a substantially cylindrical tip is connected to an ultrasonic vibrator. In horn-type ultrasonic oscillator 12 in Fig. 3, the tip of the horn facing downward has a reduced diameter and is substantially conical. However, other than such a substantially conical shape, it may be cylindrical or the like.

[0015] It is preferable that the helical ultrasonic oscillator 11 and the horn type ultrasonic oscillator 12 each independently vibrate at a frequency of 20 to 200 KHz. Either the helical ultrasonic oscillator 11 or the horn type ultrasonic oscillator 12 may be provided, or both the helical ultrasonic oscillator 11 and the horn type ultrasonic oscillator 12 may be provided. When the spiral ultrasonic oscillator 11 and the horn ultrasonic oscillator 12 are provided, it is preferable that the spiral ultrasonic oscillator 11 and the horn ultrasonic oscillator 12 are provided with their respective tips facing each other. In this case, an ultrasonic resonance core 13 made of a metal such as a titanium alloy may be provided between the ultrasonic oscillators, and the ultrasonic resonance core resonates to mix the water and the base oil more uniformly in and after the step E. The ultrasonic resonance core 13 may be a cylinder with expanded diameters at both ends, and may be installed parallel to the longitudinal direction (vertical direction in FIG. 3) of the ultrasonic water reforming treatment device 1 in FIG. 3. The expanded end of the lower end of the ultrasonic resonance core 13 may be fixed to the inner surface of the ultrasonic water reforming treatment device 1. The expanded end of the upper end of the ultrasonic resonance core 13 may be fixed to the inner surface of the ultrasonic water reforming treatment device 1. The ultrasonic resonance core resonates to mix the water and the base oil more uniformly in and after the step E. The helical ultrasonic oscillator 11 has a helical convex portion of any size and shape formed on the cylindrical shaft surface of the vibrating part. When the cylindrical part vibrates, the helical convex portion on the surface also vibrates. When the helical convex portion vibrates, the water can be efficiently treated and the subsequent mixing with the base oil can be made smooth. Furthermore, when the helical ultrasonic oscillator 11 and the horn ultrasonic oscillator 12 are provided, they may vibrate simultaneously or alternately. As shown in Fig. 3, water introduced from below into the ultrasonic water treatment device 1 moves around the spiral ultrasonic oscillator 12, passes through the inside of the ultrasonic resonance core 13, reaches the periphery of the horn ultrasonic oscillator 12, and moves from above the ultrasonic water treatment device 1 toward the next device. Note that the water may flow in the opposite direction, and may be introduced from the top in Fig. 3. By carrying out this step A, the water-containing fuel obtained by the method and apparatus of the present invention can for the first time be in a state in which water and base oil are stably dispersed.

[0016] <Process B and Equipment B> Step B in the present invention is a step using a heater device 2 in Fig. 1, in which the water obtained in step A is passed through a tube having a heater. This tube having a heater may be any tube provided with a heater in contact with the outer and / or inner surface of the tube, and in step B, water is heated to preferably 40 to 50°C. There are no particular limitations on the heater as long as it can heat water, and any known heater can be used. It is optional whether or not to perform step B, but by performing step B, the treatment in step C can be carried out effectively. When step B is not performed, the water to be treated in step A can be heated in advance. By performing step B, water and oil can be mixed more uniformly in the subsequent steps. As a result, the water-containing fuel obtained by the method and apparatus of the present invention can have water and base oil stably dispersed therein.

[0017] <Process C and Equipment C> Step C is a process in which the water obtained in step A or B is treated by passing it through an ultrasonic oscillator (ultrasonic generator), a ceramic layer, and a spiral tube type mixer, and is step 3 in FIG. FIG. 4 shows the multi-layer pipe used in step C. The water treated in step B is introduced into the multi-layer pipe 3 along the arrow shown in the lower left of FIG. 4. The introduced water enters a room in which a horn-type ultrasonic oscillator 12 and a helical ultrasonic oscillator 11 are provided. There, the water is treated through the horn-type ultrasonic oscillator 12, which vibrates at a frequency of 20 to 200 KHz, and the helical ultrasonic oscillator 11, which vibrates at a frequency of 20 to 200 KHz. Note that one each of the horn-type ultrasonic oscillator 12 and the helical ultrasonic oscillator 11 may be provided, or a plurality of each may be provided.

[0018] The water treated by the horn-type ultrasonic oscillator 12 and the spiral-type ultrasonic oscillator 11 moves upward in Fig. 4 and passes through the ceramic layer 30 filled with ceramics that react to excitation by ultrasonic waves and emit terahertz waves with a main vibration range of 0.3 THz to 3 THz for treatment. The water treated by this ceramic layer 30 moves to the upper part of the device shown in Fig. 4. The ceramic layer 30 here is preferably composed mainly of silicon dioxide or aluminum oxide. Thereafter, the water passes through water flow holes 32 in the partition tube, which is a cylindrical partition provided inside the ceramic layer 30, flows downward through the outer helical tube 33 included in the helical tube type mixer in which water passes inside the helical tube, then passes through the helical tube water flow holes 36 inside the outer helical tube 33, and is stirred while passing through the inner helical tube 34 inside the outer helical tube. The helical pipe mixer is preferably a helical pipe mixer in which the inner surface of the flow passage through which the water passes has a layer containing magnesium, manganese, ruthenium, niobium, or the like. Both the outer helical tube 33 and the inner helical tube 34 have helical projections and recesses formed inside, and water is reformed by generating cavitation in the water flowing through them. The helical tube mixer is a tube with a helical flow path inside. The water that has passed through the inner helical tube 34 passes through the water flow holes 31 of the inner helical tube and through the static mixing tube 35 inside the tube for processing. The water treated in this manner is taken out in the direction indicated by the arrow at the bottom right of the device in Figure 4. The relative positional relationships between the horn type ultrasonic oscillator, the helical type ultrasonic oscillator, the ceramic layer and the helical tube type mixer in the vertical and horizontal directions are arbitrary. In this helical tube type mixer, instead of the outer helical tube 33 and the inner helical tube 34, two helical tubes that are not in the outer and inner positional relationship may be used, or one helical tube may be divided into upstream and downstream. Also, processing may be performed using one helical tube. Furthermore, a static mixing tube 35, an inner helical tube 34, and an outer helical tube 33 may be provided in order from the inside. In this case, the cross section of the static mixing tube 35 on a plane perpendicular to the longitudinal direction has the static mixing tube 35, the inner helical tube 34, and the outer helical tube 33 formed concentrically in order from the inside. Step C and device C may be any device having a helical tube and may be provided with a static mixing tube. By carrying out step C, when mixing water and base oil in a later step, it is possible to obtain an effect of dispersing well when the base oil is heavy oil, and further dispersing well even when the base oil is other base oil such as light oil.

[0019] <Process D and Equipment D> Step D is a step using an apparatus including a tube having a manganese-containing layer on its inner surface, as shown in Fig. 1, and water is treated using an apparatus including a manganese-containing layer (special metal catalyst apparatus) 4 shown in Fig. 5. The manganese-containing layer 40 in the apparatus shown in Fig. 5 is a layer that contains a manganese compound. Water introduced from the lower left of the apparatus 4 including a manganese-containing layer shown in Figure 5 passes through a static mixing guide pipe 42 and enters the manganese-containing layer 40. The water treated in the manganese-containing layer 40 changes its flow direction downward in the upper part of the apparatus 4 including a manganese-containing layer, and passes through the static mixing pipe 35 formed in the inner pipe 41. The water that has been subjected to step D is stored in the reformed water storage tank 5 in FIG. 1 as required.

[0020] The water treated by steps A to D has an oxidation-reduction potential of -500mv to -700mv, a pH of 10.2 to 10.6, and a dissolved hydrogen content of 1.0ppm to 1.4ppm. The water stored with such characteristics can be easily mixed with the base oil in the subsequent steps. This reformed water is sent to the next process, the device shown in Figure 1, where the reformed water is mixed with the base fuel oil in a mixing process, and then sent to an ultrasonic mixing oil reforming device for the water-fuel mixing process, where primary water-oil reforming mixing is performed, and then passed through a spiral tube type mixer for secondary water-oil reforming mixing. The water is then passed through the tube of a mixer equipped with an ultrasonic oscillator and multiple spiral tubes, where tertiary water-oil reforming mixing is performed to produce a water-containing fuel that is no different from the base oil.

[0021] <Process E and Equipment E> Step E is a step according to 6 in Fig. 1, in which the water obtained in the above step D is treated with an ultrasonic mixed oil reforming device (ultrasonic resonance type mixed oil reforming device). The device used in this step is the same as the device used in step 1 in Fig. 1 within the scope of use in the above step A, and has the same structure as the ultrasonic water reforming device. Any device with any structure within the scope of use in the above step A can be used. The explanation will be given with reference to Fig. 3. In step E, the mixture of water and base oil obtained in step D above, or the water and base oil obtained in step D above, are introduced separately from the bottom of the device E. The introduced water and base oil move around the spiral ultrasonic oscillator 11, pass through the inside of the ultrasonic resonance core 13, reach the periphery of the horn ultrasonic oscillator 12, and move from the top of the ultrasonic mixed oil reforming treatment device 6 toward the next device. The inflow direction of the water may be reversed, and the water may be introduced from the top in Fig. 3. At this time, by irradiating two types of ultrasonic waves from the helical ultrasonic oscillator 11 and the horn ultrasonic oscillator 12, the water and the base oil in particular are mixed uniformly. Use of this process and apparatus improves the stability of water-containing fuels.

[0022] <Process F and Equipment F> Step F is the step according to 7 in Fig. 1, in which the mixed oil obtained in step E is passed through a mixer equipped with an ultrasonic oscillator and a spiral tube (ultrasonic generator + spiral tube type mixer). Step F is a process using the device shown in Fig. 6. The mixed oil obtained in step E is introduced into a mixer equipped with an ultrasonic oscillator and a helical tube along the upward arrow at the bottom of FIG. 6. The introduced mixed oil is ultrasonically treated by a horn-type ultrasonic oscillator 12. Then, using a multiple helical tube among the helical tubes, the oil passes through a mixed oil circulation hole 75 to the outer helical tube, passes through the outside of the outer helical tube 72, passes through a mixed oil circulation hole 71 of the outer helical tube, and is introduced into an inner helical tube 73. The oil further passes through a mixed oil circulation hole 74 of the inner helical tube, passes further inside the inner helical tube 73 that passes through the center, and is discharged from the top of the mixer equipped with an ultrasonic oscillator and a helical tube shown in FIG. 6. In process F, the material is subjected to the action of cavitation by moving up and down through the gap of the spiral tube, and at the same time, the temperature is 65 to 98°C and 3 to 10 kgf / cm 2 This promotes the mixing of water and oil. By carrying out this step F, a fuel composition in which water and base oil are uniformly dispersed can be obtained. Note that, as a mixing device equipped with this helical tube, instead of the multiple helical tubes having the outer helical tube 72 and the inner helical tube 73, two helical tubes not in the outer and inner positional relationship may be used, or a single helical tube may be used. The inner helical tube 73 and the outer helical tube 72 may be provided in this order from the inside. In this case, the cross section of the inner helical tube 73 in a plane perpendicular to the longitudinal direction of the inner helical tube 73 is formed concentrically from the inside, that is, the inner helical tube 73, the inner helical tube 73, and the outer helical tube 72. It is not necessary to pass the mixed oil further inside the inner helical tube 73.

[0023] <Process G and Equipment G> Step G is a step according to 8 in Fig. 1, in which the mixed oil obtained in step F is passed through a spiral tube mixer equipped with two types of ultrasonic oscillators, either the same type or different in wavelength or shape. Step G is a step of treating the mixed oil with a tube including the multiple ultrasonic oscillators and the spiral tube mixer shown in Fig. 7. The mixed oil processed in step F is introduced into a spiral pipe mixer 8 equipped with two types of ultrasonic oscillators, one of which is the same type or has different wavelengths or oscillator shapes, along the arrow shown in the lower left of Figure 7. The two types of ultrasonic oscillators, one of which is the same type or has different wavelengths or oscillator shapes, are preferably selected from a horn type ultrasonic oscillator and a spiral type ultrasonic oscillator in order to uniformly disperse water and base oil. The introduced water enters a room in which a horn-type ultrasonic oscillator 12 and / or a helical ultrasonic oscillator 11 are installed. There, the water is treated by the horn-type ultrasonic oscillator 12, which vibrates at a frequency of 20 to 200 KHz, and the helical ultrasonic oscillator 11, which vibrates at a frequency of 20 to 200 KHz. The oscillation frequencies of these ultrasonic oscillators may be the same or different. The mixed oil treated by the horn-type ultrasonic oscillator 12 and the helical ultrasonic oscillator 11 moves upward in FIG. 7, passes through the mixed oil circulation hole 87 of the partition tube, passes through the outer helical tube 83, then passes through the mixed oil circulation hole 82 of the outer helical tube, and passes through the middle helical tube 84 inside it to be agitated. The mixed oil that has passed through the middle helical tube 84 passes through the mixed oil circulation hole 86 of the inner helical tube and passes through the inner helical tube 85 to be agitated. Next, it passes through the mixed oil circulation hole 81 of the inner helical tube, passes downward through the static mixing tube inside the tube to be treated. The outer helical tube 83, the middle helical tube 84, and the inner helical tube 85 all have helical unevenness formed on the outer and / or inner surfaces, which generates cavitation in the water flowing inside, generating fine bubbles, and the water is treated under high temperature and high pressure conditions. By carrying out this step G, a fuel composition in which water and base oil are uniformly dispersed can be obtained. In addition, instead of the outer helical tube 83 and the inner helical tube 85, this helical tube type mixer may have two helical tubes that are not in the outer and inner positional relationship, or may have one helical tube in total. The inner helical tube 85 and the outer helical tube 83 may be provided in this order from the inside. In this case, the cross section of the inner helical tube 85 in a plane perpendicular to the longitudinal direction of the inner helical tube 85 is formed concentrically from the inside, that is, the inner helical tube 85, the inner helical tube 85, and the outer helical tube 83. It is not necessary to pass the mixed oil further inside the inner helical tube 85.

[0024] The resulting water-containing fuel is stored in the reformate secondary storage tank 9 and / or the reformate primary storage tank 10 in FIG. EXAMPLES

[0025] In this embodiment, all horn-type ultrasonic generators oscillated at 20 KHz, and all helical-type ultrasonic generators oscillated at 100 KHz. Diesel fuel and dechlorinated tap water at 18° C. were prepared. The mixtures were processed to obtain fuel mixtures containing diesel and water in the ratios shown in Nos. 1 to 3 below. No.1: 2 liters of water to 8 liters of diesel No.2: 3 liters of water to 7 liters of diesel No.3: 4 liters of water to 6 liters of diesel The diesel fuel and the water were mixed in the above-mentioned devices A to G by carrying out the above-mentioned steps A to G so as to obtain three types of blends No. 1 to 3. Specifically, the water was passed through a device equipped with one horn-type ultrasonic oscillator and one spiral-type ultrasonic oscillator, and then the water was passed through a cylindrical pipe equipped with three horn-type ultrasonic oscillators and three spiral-type ultrasonic oscillators. The inside of the cylindrical pipe was equipped with a ceramic layer, a layer containing todorokiite as a manganese-containing layer, and a spiral-type mixed section. The water and fuel oil were passed through a cylindrical pipe equipped with one horn type ultrasonic oscillator and one spiral type ultrasonic oscillator, and the mixed oil was passed through a cylindrical pipe equipped with one horn type ultrasonic oscillator and a spiral pipe type mixer, and then through a cylindrical pipe equipped with three horn type ultrasonic oscillators and three spiral type ultrasonic oscillators. Treatment time: 10 minutes, water pressure: 5kgf / cm 2 The water-mixed fuel was obtained. The outlet temperatures of each equipment during test No. 1 were as follows: Equipment A: 28°C, Equipment B: 40°C, Equipment C: 60°C, Equipment D: 65°C, Equipment E: 75°C, Equipment F: 80°C, and Equipment G: 88°C. The results are shown in Table 1. The water-mixed fuel was left for one month at 25°C. After leaving it, the presence or absence of water separation was visually confirmed. As a result, it was confirmed that water-containing fuel was obtained without any problems when the water content in the water-mixed fuel was up to 40%. Among the above-mentioned devices A to G, only device A was not used, and the water-mixed fuel was produced without adopting step A. As a result, it was visually confirmed that within one week after the production of the water-mixed fuel, some of the water separated and the water-mixed fuel became two layers. Similarly, when the water-mixed fuel was produced without using only device B, only device C, only device D, only device E, only device F, or only device G, the results were the same as when only device A was not used within about one week, and it was not possible to obtain a water-containing fuel with excellent stability.

[0027] The photographs of the water-containing fuels shown in Figure 8 are of only diesel, which is the base oil, and water-containing fuels No. 1 to No. 3 in Table 1 above (mixed oils No. 1 to No. 3, respectively) (water-containing fuels that were produced 12 hours ago). According to these photographs, all fuels are transparent and have a uniform phase without any cloudiness or separation. Mixed oils No. 1 to No. 3 were whitish and slightly cloudy immediately after production, but became transparent over time, and still had a transparent and uniform phase one month later. Except for reversing the order of steps C and D, mixed oils produced in the same manner as mixed oils No. 1 to No. 3 also had the same results as mixed oils No. 1 to No. 3, and no separation of the base oil and water occurred. In addition, stable water can also be produced by repeating steps A to D (repeating steps A to D after step D is completed) and circulating the water, thereby obtaining water-containing fuel with the same properties as the above mixed oils No. 1 to No. 3. Furthermore, the steps E to G, which are the mixing steps with water, were repeated (after step G was completed, steps E to G were repeated again), and water-containing fuels with the same properties as mixed oils No. 1 to No. 3 were obtained even after recycling. The quality of the product did not change significantly compared to the product that was not recycled, and separation of the base oil and water did not occur even after more than a month had passed. [Industrial Applicability]

[0028] The water-containing fuel produced by the present invention is stable even after long-term storage, with no particular change in appearance or physical properties. The production process can be automated, and the method and equipment do not use additives, making continuous and mass production possible. In addition, it can contribute to global warming countermeasures by reducing the amount of carbon dioxide generated. [Explanation of symbols]
