Description

  The present invention relates to a continuous production method of emulsion oil for adding water to heavy oil or light oil at a predetermined ratio to make it emulsified and use it as a fuel for internal combustion engines and combustion devices, and continuous production of emulsion oil by the method. The invention relates to a suitable emulsion oil generator.

  Many fossil fuels are used for the operation of many devices and equipment, both industrial and consumer, especially considering the overall convenience such as regionality, portability, ease of transportation and storage, and price. Thus, petroleum-based fuels such as light oil and heavy oil are widely used. In Japan, all petroleum-based fuels must be relied upon for imports, so the price fluctuates greatly, and carbon dioxide emissions, which are considered the cause of global warming, are inevitable. However, it is cheaper than electricity, LPG, LNG, and the like, and heavy oil and light oil are maintained as a fuel for heat engines represented by diesel engines. In order to use such heavy oil and light oil more economically, an emulsion (emulsification) oil in which a water component is added and dispersed in an appropriate weight ratio has attracted attention as an economical fuel oil.

  Emulsion oil (hereinafter also referred to as “emulsion fuel” which is synonymous) is obtained by dispersing water in oil as fine particles and mixing and emulsifying. Therefore, a means for rotating the stirring blade by adding water together with an emulsifier as appropriate to the heavy oil or light oil in the oil tank has been adopted as a primitive production means for the emulsion fuel. However, since the generation means by the rotation of the stirring blades must basically rely on batch processing, there is some unevenness in the component ratio of the emulsion fuel to be manufactured, depending on the stirring manufacturing process from the preparation. There was a drawback that occurred. Furthermore, it is known that the greatest difficulty of emulsion fuel is that if left as it is, the oil component and the water component will eventually be separated into two layers and agglomerate will occur.

  In view of such problems, Patent Document 1 discloses an emulsion fuel, a manufacturing method thereof, and an emulsion fuel driving apparatus that ensure the stability over time by ultra-fine dispersion water particles. However, it is difficult to completely prevent oil-water two-layer separation only by refining water particles. Further, in Patent Document 2, a positive electrode P is arranged on the upper surface of the oil tank, a negative electrode M is arranged in the oil at the bottom of the oil tank, and a high voltage of each polarity is applied between both electrodes to cause plasma discharge. In addition, it is disclosed that food, cosmetics and the like can be obtained in addition to the emulsion fuel in which oil and water are sufficiently mixed and emulsified. However, even if emulsion fuel is generated by such plasma discharge, the emulsion generation of the raw material oil filled in the oil tank is a batch process for each oil tank. Therefore, for example, cosmetics that are sufficient even on a small scale are usually not suitable for emulsion fuel production on the premise of mass production.

Patent Document 3 discloses a technical means for producing an emulsion fuel oil by an emulsifier using, as an emulsifier, a mixed surfactant obtained by mixing a lipophilic surfactant having a predetermined range of HLB value and a hydrophilic surfactant in an appropriate ratio. Is disclosed. In the technical means using such a mixed surfactant as an essential requirement, the surfactant is basically an impurity for the fuel, so that the use as a fuel may be limited.
Japanese Patent Laid-Open No. 2-105890 JP2007-224156 JP2003-113385A

  SUMMARY OF THE INVENTION An object of the present invention is to provide a continuous production method of emulsion oil capable of continuously producing homogeneous emulsion oil by providing independent mixing means on the oil component side and water component side of the emulsion oil production and mixing tank. And providing an apparatus for continuous production of emulsion oil. In addition, although heavy oil, light oil, etc. are assumed as a basic oil component of emulsion oil formation, it is applicable also to another oil component.

  The object of the present invention is to form a lower mixing area MA and an upper emulsion oil take-off area 0A with a metal filtering means 2 fixed above the middle inside the tank as a boundary. The first oil mixing means 10 and the second fluid mixing means 20 are fixed to the outer wall belonging to the mixing area MA of the emulsion oil generating and mixing tank, and taken out from the mixing area. A negative diffusion formed around the discharge port of the first fluid mixing means when a radiative diffusion flow generated by press-fitting the fluid in the middle of mixing into the first fluid mixing means 10 is returned to the mixing region. The mixing region is obtained by sucking the oil component supplied from the fuel tank by pressure and further fluidly mixing the sucked oil component and the fluid in the course of mixing that generates the radiation diffusion flow. And when the radiation diffusion flow generated by press-fitting the fluid in the process of mixing taken out from the mixing region into the second fluid mixing unit 20 is returned to the mixing region, the second The water component supplied from the water tank is sucked by the negative pressure formed around the discharge port of the fluid mixing means, and the sucked water component and the fluid in the course of mixing that generates the radiation diffusion flow are further fluidly mixed. And the step of discharging into the mixing region and the emulsification and mixing of the oil component rich mixture and the water component rich mixture proceed to reach a desired value, and the emulsion oil above the emulsion oil producing and mixing tank This is solved by a method for continuously producing emulsion oil, comprising the step of taking out emulsion oil that has passed through the take-out area OA.

  Moreover, the subject of this invention can make the mixing ratio of the said oil component and water component into the range of 6: 4-8: 2, and enables it to select suitably according to the use of the emulsion oil manufactured. This can be solved more advantageously. Furthermore, in an application in which the time from the time when the emulsion oil is produced until it is supplied to the utilization device is increased, 2 to 4% of an emulsifier is added in the fluid mixing process of the oil component in the first fluid mixing device 10. Can be more advantageously solved. The metal filtering means 2 and 4 may be a punching metal obtained by punching a number of holes in a wire mesh or stainless steel plate using a stainless steel wire.

  An object of the present invention is to provide an emulsion oil generation and mixing tank for emulsifying and mixing an oil component and a water component supplied at a predetermined ratio, as described in claim 5, and above the middle of the tank On the outer wall belonging to the mixing region of the emulsion oil generating and mixing tank, the emulsion oil generating and mixing vessel 1 formed with the lower mixing area MA and the upper emulsion oil take-out area OA with the fixed metal filtration means 2 as a boundary. The new oil component supplied from the fuel tank is sucked by the negative pressure generated by press-fitting the fluid in the process of mixing, which is fixed and taken out from the mixing region, into the first fluid mixing means. A first fluid mixing means for discharging the oil component and the fluid in the mixing process generating the radiation diffusion flow into the mixing region while further diffusing and mixing the oil component; It is fixed to the outer wall belonging to the mixing region of the John oil production mixing tank, and is supplied from the water tank by the negative pressure generated by press-fitting the fluid in the process of mixing taken out from the mixing region into the second fluid mixing means. A second fluid mixing means 20 that sucks a new water component and discharges the sucked water component and the fluid in the mixing process generating the radiation diffusion flow into the mixing region while further diffusing and mixing; This is solved by an emulsion oil continuous production apparatus comprising emulsion oil delivery means 7 for taking out emulsion oil from the emulsion oil take-out area.

  The preferred component ratio of the oil component and the water component supplied to the emulsion oil producing and mixing tank can be changed depending on the use and usage of the emulsion oil to be produced. For example, when used as a fuel for diesel engines or other prime movers, it is preferable to select a slightly larger amount of oil component. On the other hand, in the case of using a fuel such as a burner for various heating devices such as a heating device, an agricultural device, and an industrial device, fuel consumption can be further reduced by reducing the blending ratio of oil components.

  According to the method for continuously producing emulsion oil and the apparatus for continuously producing emulsion oil according to the present invention, the mixing region of the emulsion oil generating and mixing tank is compared with the emulsion oil generating and mixing tank 1 containing the metal filtration means 2 and 4. An oil component mixture that is sucked and mixed from an external fuel tank through an oil guide pipe by the negative pressure formed by press-fitting the fluid in the process of taking out from the first fluid mixing means 10 into the mixing region. The fluid is fed continuously and taken out from the mixing region of the emulsion oil producing and mixing tank, and the fluid under mixing is pressed into the second fluid mixing means 20 from the water tank through the conduit. The oil component and the water component are forcedly fed while continuously feeding the water component mixture sucked and mixed into the mixing area. Emulsion oil is produced by 拌 mixed.

  Thus, the emulsification capacity in the process of producing emulsion oil depends on the mixing ability of the first and second fluid mixing means attached to the outer wall of the emulsion oil producing and mixing tank. As mixing means for mixing the oil component sucked from the external oil component tank while diffusing and radiating the fluid in the course of mixing taken out from the mixing region of the emulsion oil generation mixing tank, for example, “Mixing” disclosed in Japanese Patent No. 3751308 The machine can be suitably applied. As will be described later, the details of the mixer are substantially cylindrical and are closed except for the first, second and third fluid inlets and the fluid discharge opening extending around the second fluid inlet. Surrounded by a container. Around this fluid discharge port is a structure that forms a negative pressure by forced discharge accompanied by the radiation diffusion of the fluid, and using this negative pressure, the oil component or water component is sucked from each pipe and mixed operation It has a structure that repeats.

  The oil-water mixing action in the emulsion oil generating and mixing apparatus according to the present invention is the oil component mixing means and the second fluid as the first fluid mixing means attached to the outer wall in the range belonging to the mixing region of the emulsion oil generating and mixing tank. It is executed individually by the water component mixing means which is a mixing means. Such a mixing means, unlike the stirring operation by the common stirring blade disposed inside the mixing tank main body, individually controls the operation of each mixer without being influenced by the other according to the demand situation of the emulsion oil component. The mixing effect can be adjusted arbitrarily. Then, the emulsion oil component which has been sufficiently mixed and has a reduced specific gravity passes through the metal filtration means and rises to the emulsion oil take-out region. Therefore, the extracted emulsion oil component is in a preferred emulsion state.

  The component ratio of the emulsion oil can be achieved, for example, by controlling the operation of the liquid press-fitting pump in the course of mixing with respect to the first fluid mixer connected to the oil guide pipe when the oil component is increased. Therefore, it is easy to obtain a component ratio that matches each demand means. The metal filtration means is not only a boundary between the fluid mixing area and the emulsion oil take-out area, but is lost when the flow velocity of each fluid that was flowing vigorously in the mixing area passes through the filtration means. In the emulsion oil take-out region, there is an effect of restraining it to be almost stationary.

  Hereinafter, preferred embodiments of an emulsion oil continuous production method and continuous production apparatus according to the present invention will be disclosed with reference to the accompanying drawings. FIG. 1 is a front view showing a basic configuration of an emulsion oil generating and mixing tank 1 which is a main part of an emulsion oil continuous production apparatus according to the present invention, and FIG. 2 is a plan view. In addition, although the oil component used in a present Example assumes heavy oil or light oil, it is applicable also to another kind of oil component.

  The emulsion oil generation and mixing tank 1 is a metal container having a circular cross-sectional shape, and in this embodiment, an effective volume of 50 liters is used, but it can be appropriately changed according to the application. The shape of the container forming the mixing tank is a cylindrical shape with little possibility of fluid retention. Inside the vicinity of about 2/3 of the tank height with respect to the bottom of the emulsion oil producing and mixing tank 1, a metal mesh 2 illustrated by phantom lines, preferably a stainless steel metal mesh, is fixed as a first metal filtration means. The lower part of the first metal filtration means 2 is the mixing area MA, and the upper part is the emulsion oil take-out area OA (see FIG. 5). The wire mesh may be a punching metal in which a large number of through holes having a diameter of several millimeters are formed on a stainless steel plate.

  Near the bottom inside the emulsion oil generating and mixing tank 1, a metal mesh 4 is disposed and fixed as a second metal filtration means on the entire inner periphery of the mixing tank, slightly above the drain discharge part (DR) 3. Oil components such as heavy oil and light oil, which are processing components in the emulsion oil generation mixing tank 1, and added water components may contain sludge, impurities, and other foreign components. Since it is not preferable that such a foreign component is mixed into the emulsion oil, the foreign component filtered by the wire mesh 4 is discharged in a timely manner by opening a valve connected to the drain discharge portion (DR) 3. In this case, each fluid that has flowed vigorously in the mixing area MA is lost so that its flow velocity is lost when passing through the wire mesh 4 and is suppressed so as to be almost stationary, and the bottom plate formed by tilting the foreign material component is formed. And can be easily discharged from the drain discharge portion 3. FIG. 4 shows an internal configuration example of the emulsion oil generation and mixing tank 1 in the AA ′ cross-sectional view of FIG. 2, in order to describe the operating state of the emulsion oil continuous production apparatus according to the present invention described later. FIG.

  A thermometer 5 capable of measuring the temperature of the fluid in the tank at the time of the reaction is attached to an appropriate portion of the emulsion oil generating and mixing tank 1, in this embodiment, at an almost intermediate position. Since the viscosity of the oil component changes depending on the temperature, the temperature change is to be monitored. Further, a liquid level gauge 6 is disposed between the first metal filtration means 2 and the upper end portion in the emulsion oil generation / mixing tank 1. This liquid level gauge 6 makes it possible to confirm whether or not the liquid level at which the product can be taken out is maintained in the emulsion oil taking out area OA.

  A first fluid mixing means 10 and a second fluid mixing means 20 that exhibit the main functions and effects of the present invention are respectively attached to the emulsion oil generation and mixing tank 1. As these fluid mixing means 10 and 20, for example, a “mixer” disclosed in Japanese Patent No. 3751308 related to the same inventor as the present application can be suitably applied. Although these mixers 10 and 20 have basically the same structure although the mixed components are different, the fluid mixer 10 for oil components will be described below.

  As shown in the cross-sectional view of FIG. 3, the mixer 10 has a substantially cylindrical hollow portion, and both ends thereof are substantially bullet-like shapes closed by a hemisphere and a semi-ellipsoid that can close the opening. It is surrounded by the casing 101. The first fluid inlet port 102, the second and third fluid inlet ports 103 and 104, and the fluid discharge opening 109 extending around the second fluid inlet port are closed. The first fluid inlet 102 is shifted from the center of the casing 101 from the right side. A partition wall 105 is provided on the right side of the fluid inlet 102 in the casing 101 and is separated into a first chamber having a large volume and a second chamber having a small volume. Further, a cylindrical body 106 for discharging the fluid in the first chamber across the second chamber to the outside on the right end passes through the central portion of the partition wall 105.

  Around the outlet 107 of the short cylindrical body 106 to the outside of the casing, in order to generate a negative pressure, the wide opening side of the bowl-shaped body 108 whose bottom side is opened with a small diameter is fixed to the casing, and the narrow opening extends outside. It is arranged to face. The second fluid introduction port 103 is disposed in a state where it enters the casing 101 rather than the narrow opening of the bowl 108. Note that the third fluid introduction port 104 is connected to a fluid pipe such as a liquid or gas component, for example, an emulsifier, if necessary, but is blocked when the third fluid is not used.

  When fluid is pressed into the fluid mixer 10 or 20 formed as shown in FIG. 3 from the first fluid inlet 102 via a pump, the fluid continues to swirl along the inner wall surface of the casing 101. As the fluid enters, the pressure becomes high and is discharged from the cylindrical body 106 while diffusing outward as indicated by an arrow 110. Along with such intense diffusion and release of the first fluid, a negative pressure is generated inside the rod-shaped body 108 whose bottom side is opened. The second fluid is sucked from the opening of the supply pipe 103 for the second fluid by the negative pressure formed in this way. As soon as the second fluid sucked in this way is sucked from the opening, it is diffused and radiated while being immediately absorbed and mixed in the first fluid being diffused and released. Therefore, the first fluid (O + W: fluid in the middle of mixing consisting of an oil component and a water component) and the second fluid (O: O: W) supplied from the mixing region MA of the emulsion oil generation mixing tank 1 according to the present invention. Either the oil component or W: water component) is returned to the mixing region MA of the emulsion oil generation and mixing tank 1 in a state in which the oil component or W: water component is reliably stirred and mixed.

  In the present invention, the first fluid mixer 10 or 20 is attached in the vicinity of the second fluid inlet so as to surround the fluid outlet 107 of the casing 101 with a small-diameter opening with the bottom side cut off and the wide mouth side surrounding the fluid outlet 107. A negative pressure generated in the rod 108 according to the diffuse radiation of the fluid is used. By this negative pressure, the oil component or water component, which is the second fluid, is sucked and introduced through a pipe from the outside, and is integrated with the diffuse radiation flow of the fluid that is composed of the oil component and water component, which are the first fluid. As a result, strong stirring and mixing can be achieved. Therefore, the oil component or the water component which is the second fluid is drawn into the strong diffused radiation flow of the first fluid that is already in the process of mixing immediately after being sucked and discharged from the pipe. Stir mixing is achieved simultaneously.

  The first fluid mixer 10 and the second fluid mixer 20 that exhibit such a function are attached and fixed to the outer wall surface of the mixing region of the emulsion oil generation and mixing tank 1. In addition, the oil component and water component which are the 2nd main components are each supplied by the oil guide pipe or water guide pipe which penetrates the inside of the emulsion oil production | generation mixing tank 1, and are in the middle of mixing with the oil and water which are the 1st main components. Ingredients are removed from the mixing region via metal tubes and are pressed into the first fluid inlet via a pressure pump.

  In the first fluid mixer 10 or 20 fixed to the outer wall of the mixing region of the emulsion oil generation mixing tank 1, the oil component or water component sucked from the outside is taken out from the mixing region and pumped to form a diffuse radiation flow. The fluid in the course of mixing both components of the oil and water is mixed repeatedly. As described above, in the emulsion oil generation and mixing tank 1 according to the present invention, the powerful mixing action mainly composed of the respective components in the fluid mixers of the oil component mixer 10 and the water component mixer 20 attached to the outer wall of the mixing region. Are repeated continuously. Thereafter, the components in the mixing area MA are repeatedly mixed and the components that have reached the desired emulsion oil state pass through the stainless steel filtering means 2 and move to the emulsion oil take-out area OA. The emulsion oil component thus obtained is taken out from the emulsion oil delivery means 7 above the mixing tank by a pump and supplied to a demanding apparatus such as a diesel engine or a burner as appropriate.

  4 and 5 are diagrams for explaining a series of operating states in the emulsion oil generation and mixing tank 1. In the mixing tank 1, as shown in FIG. 4, a lower limit float switch (floating ball switch) FS1, an intermediate float switch FS3, and an upper limit float switch FS2 are arranged. When emulsion oil is produced by the emulsion oil producing apparatus according to the present invention, initially, heavy oil as a raw material for producing emulsion oil from the upper inlet with respect to the emulsion oil producing and mixing tank 1 as shown in FIG. Or add oil components such as light oil. The injection amount is up to a position (mixing area MA) where the lower limit float switch FS1 is turned ON, and is an amount that can be confirmed by the level meter (liquid level meter) 6.

  When the lower limit float switch FS1 is turned on, the drive pump for the mixer and the fluid supply pumps (pumps 1 and 2) for supplying the fluid in the mixing area MA of the mixing tank 1 to the mixer are turned on. The operation starts. Next, when the intermediate float switch FS3 is turned on, the water component introduction solenoid valve 12, the oil component introduction solenoid valve 11, and the emulsifier introduction solenoid valve 13 are turned on, and the water component, oil component, and if necessary, the emulsifier component are mixed. Supplied to the machine. On the other hand, when the lower limit float switch FS1 is turned off, the fluid mixer drive pump and the fluid supply pump are turned off and are not driven. When the upper limit float switch FS2 is turned on, the water component introduction solenoid valve 12, the oil component introduction solenoid valve 11, and the emulsifier introduction solenoid valve 13 are turned off, and the water component, oil component, and emulsifier component are not supplied to the mixer.

  Thus, after oiling to a predetermined level (a), valves belonging to each system such as an oil component tank, a water component tank, and an emulsifier tank which are omitted in the figure are opened, and before these operations are started. After confirming that the procedure is complete, the apparatus according to the present invention performs a series of operations, as shown in FIGS. First, as shown in b, the fluid supply pumps 1 and 2 and the drive pump for the mixer, which are not shown in the figure, for press-fitting the fluid in the mixing region into the fluid mixers 10 and 20 are operated. When these two pumps are operated, the fluid in the mixing zone, that is, the fluid which is a mixture of oil component and water component but not completely mixed, is injected from the inlet below the mixer and negatively flows near the outlet. Create pressure. By utilizing this negative pressure, water components such as c or oil components such as d are introduced into the discharge ports of the respective mixers through respective introduction pipes (an emulsifier is introduced if necessary). Then, the mixture diffusion action is repeated in the mixing region as e and f.

  As a result of repeated diffusion of the mixture through such a process, the specific gravity gradually decreases, the emulsification progresses, and the flow velocity of each fluid that has flowed vigorously in the mixing region is almost lost when passing through the filtering means. The emulsion oil that has been in a stationary state passes through a metal filtration means 2, for example, a wire mesh made of stainless steel, and rises into the upper emulsion oil extraction area OA. Since the components that have risen up to the emulsion oil take-out region are reliably emulsified, they are sent as fuel to an external combustion device or a temporary storage place as in g.

  Since the present invention employs such a configuration, it is possible to efficiently produce an emulsion oil that is surely emulsified. As a result of good emulsification, the resulting emulsion oil is used as a fuel for internal combustion engines such as vehicles, ships, etc. as well as various dryers, boilers, heaters, etc. used in industrial and agricultural applications. It is suitable and can contribute to energy saving and resource saving. Combustion of fossil fuels inevitably generates carbon dioxide, which is contrary to the prevention of global warming. However, the use of such emulsion oil will reduce fossil fuel consumption by 20 to 30%. A significant effect can also be expected from the aspect of suppression of conversion.
