Conventionally, when operating an engine such as a diesel engine, additives such as fuel and water are used to reduce harmful substances such as nitrogen oxides (NO x), sulfur oxides (SO x) and graphite in exhaust gas. It is known to use a water emulsion fuel mixed with these. Since the water emulsion fuel is an insecure fuel formed by forcibly mixing oil and water having no mutual affinity, additives are used for the water emulsion fuel in order to facilitate mixing of the fuel with additives such as water. . As the additive, for example, a surfactant is used.

The water emulsion fuel should not be separated in a short time after production, and should not be low in oil and water dispersion, and fine particles having an average particle size of 5 μm or less are required.

  For this reason, in the conventional water emulsion fuel supply apparatus, a filter used for mixing oil and water into fine particles is made of Shirasu Porous Glass having a diameter of 5 μm as a material. The thing formed in disk shape or cylindrical shape is used. At this time, several siras porous glass filters were arrange | positioned in order of big diameter, and the particle | grains of oil and water were made into the fine granules of 5 micrometers or less in steps.

  Here, shiras is a type of volcanic eruption widely distributed in the southern Kyushu region of Japan, and the minerals of SiO2, Ai2O3, Fe2O3, FeO, MgO, CaO, Na2O, K2O, etc., which are the main components of magma, are gathered together. It was formed by crystallization and explosive eruption shortly thereafter. The syras porous glass is formed by synthesizing syras, lime, and boric acid at a temperature of about 1350 ° C., and performing an acid treatment with heat treatment or hydrochloric acid again.

 Patent Document 1 discloses an example of a technique related to an emulsion fuel. Patent Document 2 discloses an example of a technique related to a Siras porous glass filter used for mixing light oil and water flowing at high pressure.

 The adjustment valves T1 and T2 are arranged to adjust the flow rate of fossil fuel or water flowing through the pipes H41 and H42.

 The switching valves B1 and B2 are all three-way valves, and control the outflow direction of the incoming fossil fuel or the mixed fuel containing the fossil fuel and water together with the outflow amount, as shown in FIG. B1 is disposed between the pipes H1, H2, and H16, and controls the outflow direction of the fossil fuel flowing from the pipe H1 in the direction of the pipe H2 or the direction of the pipe H16. Here, when only the fossil fuel is supplied to the engine E, the switching valve B1 switches the outflow direction of the fossil fuel flowing from the pipe H1 in the direction of the pipe H16. On the other hand, when the fossil fuel containing fossil fuel and water is supplied to the engine E, the switching valve B1 switches the outflow direction of the fossil fuel flowing from the pipe H1 in the direction of the pipe H2. .

  As shown in Fig. 1, the switching valve B2 is disposed between the pipes H14, H15 and H18, and mixed fuel containing fossil fuel, fossil fuel and water introduced from the pipe H14. The outflow direction of the switch is controlled to be in the direction of the pipe H15 or the direction of the pipe H18. Here, when only the fossil fuel is supplied to the engine E, the switching valve B2 switches the outflow direction of the fossil fuel flowing from the pipe H14 in the direction of the pipe H18. On the other hand, in the case of supplying the fossil fuel containing fossil fuel and water to the engine (E), the switching valve (B2) is a pipe (outlet) of the fossil fuel containing the fossil fuel and water flowing from the pipe (H14) pipe ( Switch to H15).

  Next, the operation of the fuel supply device according to the embodiment of the present invention will be described with reference to the drawings.

  First, the case where the fossil fuel containing fossil fuel and water is supplied to the engine E is demonstrated. At this time, the switching valve (B1) is controlled to switch the outflow direction of the fossil fuel flowing from the pipe (H1) in the direction of the pipe (H2), the switching valve (B2) is a fossil fuel and water introduced from the pipe (H14) The outflow direction of the fossil fuel to be included is controlled to be switched in the direction of the pipe H15.

 As shown in FIG. 1, the fossil fuel flowing out of the fossil fuel tank 10 is discharged by a pressure pump P1 to a switching valve B1, a pipe H1 to H4, a filter F1, and an adjustment valve ( Through T1), it is pumped to the pipe H7. Moreover, the water which flows out from the water tank 20 by the pressure pump P2 is pumped to the pipe H7 via the filter F2, the pipe H6, and the control valve T2. At this time, when fossil fuel is used, the ratio between diesel and water is set to 4: 1. The ratio of this diesel oil and water is adjusted by adjustment valves T1 and T2. In addition, the ratio of fossil fuel and water can be changed according to the kind, purpose of use, etc. of fossil fuel.

 Next, by the pressure pump P3, the fossil fuel from the fossil fuel tank 10 and the water from the water tank 30 are passed through the pipe H8 to the inlet 101 of the filter device 100a. It is supplied by pressure feeding.

 Next, by the filter device 100a, the fossil fuel and water fed by the pressure pump P3 and fed from the inlet 101 are mixed, and the mixed fuel containing fossil fuel and water is uninjected and the outlet 102 Out). In addition, the detailed description about the operation | movement of the filter apparatus 100a is mentioned later.

  Next, a mixed fuel containing fossil fuel and water, which flows out from the outlet 102 of the filter device 100a, flows into the mixing tank 30 through the pipe H9.

 As shown in Fig. 1, the mixing tank 30 is connected to a circulation flow path composed of the filter device 100b, the pipes H10 to H12, and the pressure pump P4, and is driven by the power of the pressure pump P4. , The mixed fuel containing fossil fuel and water in the mixing tank 30 is repeatedly fed to the inlet 101 of the filter device 100b to be granulated inside the filter device 100b to be fine-grained. It flows out of the outlet 102 of 100b). In addition, the mixed fuel including fossil fuel and water flowing out of the outlet 102 is introduced into the mixing tank 30 again. In addition, the detailed description about the operation | movement of the filter apparatus 100b is mentioned later with an operation description of the filter apparatus 100b.

  By such a configuration, the mixed fuel stockpiled and stored in the mixing tank 30 is always maintained in an unpartitioned state, and the unpartitioned mixed fuel can be supplied to the engine E more stably.

 Next, the mixed fuel containing fossil fuel and water is supplied from the mixing tank 30 to the engine E through the pipe H13, and is ejected from an injection device (not shown) in the engine E. Then, the mixed fuel ejected from the injector of the engine E is ignited.

  At this time, among the mixed fuel injected by the injector in the engine E, the fine particles of the fossil fuel receive heat and burn. At the same time, the fine particles of water contained in the mixed fuel receive radiant heat by the combustion of the fine particles of fossil fuel, reach boiling points, and in turn cause microexplosion, thereby reducing the fine particles of surrounding fossil fuel. Dispersion in all directions causes secondary microparticles. The mixed fuel remaining in the engine E flows into the mixing tank 30 through the switching valve B2 and the pipes H14 and H15.

  In this way, when the fossil fuel is made into ultrafine particles at the moment, the contact area between the fossil fuel and the air is increased, and the complete combustion is rapidly performed, thereby reducing the generation of smoke and unburned carbon in the combustion exhaust gas. .

 In general, NO x generated by the chemical reaction between nitrogen (N) and oxygen in the air is mainly used in the process of combustion, that is, in the process of combustion of gaseous components → combustion of carbon powder → coke state unburned powder residue. Coal burning causes a large amount of localized hot spots due to sparks.

  Since the fine particles of fossil fuel and water in the mixed fuel supplied by the fuel supply device according to the present invention use the filter devices 100a and 100b described later in detail, they are extremely fine and the water is uniform in the fossil fuel. It is distributed. Therefore, the flame can be made uniform, and most of the fossil fuel and the fine particles of the water in the mixed fuel are completely burned without generating a high temperature region locally. Therefore, generation of NO x can be reduced.

 In addition, nitrogen is contained in fossil fuels in addition to air, and by burning fossil fuels, nitrogen in fossil fuels is converted into NO x and NO x is generated.

  Next, the case where only fossil fuel is supplied to the engine E is demonstrated.

 At this time, the switching valve (B1) is controlled to switch the outflow direction of the fossil fuel flowing from the pipe (H1) in the direction of the pipe (H16), the switching valve (B2) is the outflow direction of the fossil fuel flowing from the pipe (H14) Is controlled in the direction of the pipe H18.

 As shown in Fig. 1, the fossil fuel flowing out of the fossil fuel tank 10 is discharged by the pressure pump P1 through the switching valve B1, the pipes H1, H16, H17, and the filter F3. , It is supplied to the engine E, and is ejected from an injector (not shown) in the engine E. Then, the mixed fuel ejected from the injector of the engine E is ignited. And fossil fuel injected by the injector in the engine E receives heat and burns. The fossil fuel remaining in the engine E flows into the fossil fuel tank 10 through the switching valve B2 and the pipes H14 and H18.

 In this way, the first fuel supply for supplying the fossil fuel to the inlet port 101 of the filter device 100a from the fossil fuel tank 10 through the pressure pump P1 together with the water in the water tank 20 is supplied. A switching valve B1 capable of setting a route and a second fuel supply route for supplying fossil fuel from the fossil fuel tank 10 to the engine E to switch the first or second fuel supply route. By further setting, any one of two types of fuels, a mixed fuel containing fossil fuel and water or a fossil fuel, can be selected to supply fuel to the engine (E).

  Next, the structure of the filter apparatus 100a, 100b which concerns on embodiment of this invention is demonstrated by drawing.

 2 is a schematic diagram showing the configuration of a filter device according to an embodiment of the present invention, the left side of which is an external view, and the right side thereof is a sectional view. 3 is a cross-sectional view taken along the line A-A of FIG.

It is a schematic cross section. In addition, each arrow in FIG.2 and FIG.3 has shown the direction which fossil fuel, water, or the mixed fuel containing these fossil fuel and water flows.

 As shown in FIG. 2, the filter apparatus 100a, 100b which concerns on embodiment of this invention is equipped with the outer cylinder part 110 and the inner cylinder part 120. As shown in FIG.

 As shown in Figs. 1 and 2, the outer cylinder portion 110 is formed in a cylindrical shape. The inflow port 101 is arrange | positioned at the edge part of the outer cylinder part 110. As shown in FIG. The end surface 111 is arrange | positioned at the inflow port 101 side of the outer cylinder part 110. As shown in FIG.

  An inlet through-hole 112 is formed from the end face 111 toward the inlet 101. The inlet through-hole 112 includes fossil fuel, water, and mixed fuel containing these, which are pressurized and supplied from the inlet 101, and the inner surface 113b of the side wall 113 of the outer cylinder portion 110 and the inner portion thereof. It is arrange | positioned in order to guide | induce between the outer surface 123a of the side wall 123 of the cylinder part 120. FIG. Moreover, the screw part 114 is formed in the inner side 113b of the side wall 113 of the outer cylinder part 110 on the opposite side to the inflow port 101 side. As the material of the outer cylinder part 110, stainless steel, such as SUS303 or SUS304, is used, for example. Here, for example, the outer diameter of the outer cylinder portion 110 is 42 mm, the inner diameter is 30 mm, and the maximum length in the longitudinal direction is 140 mm.

  As shown in Figure 2, the inner cylinder portion 120 is formed in a cylindrical shape. The inner cylinder part 120 is arrange | positioned inside the outer cylinder part 110. As shown in FIG. Moreover, the outlet port 102 is arrange | positioned in the end part opposite to the inflow port 101 among the inner cylinder parts 120. As shown in FIG. Moreover, the screw part 124 is formed in the inner peripheral part 110 in the outer peripheral surface of the edge part of the outlet port 102 side.

 In addition, the inner cylinder portion 120 is attached to the outer cylinder portion 110 by screwing the screw portion 124 of the inner cylinder portion 120 into the screw portion 114 of the outer cylinder portion 110. At this time, a gap is disposed between the inner surface 113b of the side wall 113 of the outer cylinder portion 110 and the outer surface 123a of the side wall 123 of the inner cylinder portion 120. Here, as shown in Fig. 2, this gap is set substantially constant. Here, when the inner diameter of the outer cylinder part 110 is 30 mm as mentioned above, for example, the outer diameter of the inner cylinder part 120 shall be 20 mm, and the outer surface 123a of the side wall 123 of the inner cylinder part 120 will be described. The gap between them was uniformly set to 5 mm.

  Thus, by making the clearance gap between the outer surface 123a of the side wall 123 of the inner cylinder part 120 substantially constant, the outer surface 123a of the side wall 123 of the inner cylinder part 120 of the outer cylinder part 110 is carried out. The flow rate of fossil fuel and water flowing between the inner surface 113b of the side wall 113 can be stabilized with good balance. In addition, as described above, the gap between the inner surface 113b of the side wall 113 of the inner cylinder portion 110 and the outer surface 123a of the side wall 123 of the inner cylinder portion 120 is substantially constant. Although it is preferable, it is not necessary to limit to this.

  Moreover, since the outer cylinder part 110 and the inner cylinder part 120 are formed in the cylindrical shape, the outer surface 123a of the side wall 123 of the inner cylinder part 120, and the inner surface (side wall 113 of the outer cylinder part 110) are made. The flow rate of fossil fuel and water flowing between 113b) can be stabilized with good balance. Moreover, you may form the outer cylinder part 110 and the inner cylinder part 120 in cylindrical shape other than a cylindrical shape.

  As shown in Fig. 1, the outlet through-hole 122 is formed toward the outlet 120 from the inner side of the side wall 123 of the inner cylinder portion 120. As shown in FIG. The outlet hole through-hole 122 is a fossil fuel, water, a mixed fuel containing these, etc., which are conveyed through the inside of the outer cylinder portion 110 and the inside of the inner cylinder portion 120, and the outlet 102. It is excreted to drain from.

  As shown in FIG. 1, when the impact surface 125 collides, the inflow port 101 of the inner cylinder part 120 collides with the fossil fuel supplied from the inlet port 101, water, or a mixed fuel including these. The tip of the side is closed and excreted. When the plurality of through holes 126 collide with each other, fossil fuel that collides with the water 125, water, or a mixed fuel containing these are formed on the inner surface of the outer surface 123a of the side wall 123 of the inner cylinder portion 120. It is formed in the side wall 123 of the inner cylinder part 120 so that it may flow to 123b. The plurality of through holes 126 are evenly disposed on the side wall 123 of the inner cylinder portion 120. Here, for example, four through holes 126 are disposed along the outer circumference of the side wall 123 of the inner cylinder part 120, and 5 to 10 through holes 126 are provided along the longitudinal direction of the inner cylinder part 120. ) Are arranged and set, and a total of 20 to 40 through holes 126 are formed in the side wall 123 of the inner cylinder part 120.

 The plurality of through holes 126 are formed to extend from the inner surface 123b of the side wall 123 of the inner cylinder portion 120 toward the outer surface 123a. For this reason, the fossil fuel and water which collide with the collision surface 125 can be smoothly flowed from the outer surface 123a side of the side wall 123 of the inner cylinder part 120 toward the inner surface 123b. Here, the inner diameter in the inner surface 123b of the side wall 123 of the inner cylinder part 120 is formed so that it may be about 1.0 mm or less. That is, the minimum diameter of the through hole 126 is made about 1.0 mm or less. By doing in this way, the average particle diameter of each particle of the mixed fuel which flows out from the outlet 102 can be reliably set to 5 or less. Also, the maximum of the through hole 126

The inner diameter was, for example, about 3 mm, and the minimum inner diameter of the through hole 126 was, for example, 0.7 mm. Stainless steel is used for the material of the inner cylinder part 120 of the through-hole 126, for example.

 Next, the operation of the filter devices 100a and 100b will be described with reference to the drawings.

 As shown in Fig. 1, fossil fuel, water, or a mixed-heap fuel containing these are pumped into the outer cylinder portion 110 at the inlet 101, at this time, fossil fuel, water, or mixed fuel containing them. Collides strongly with 125, and fossil fuel, water, or a mixed fuel containing these are atomized by the impact of the collision.
