Description

  The present invention relates to a method for producing an emulsion fuel oil in which water and a base fuel oil are emulsified and mixed.

  In recent years, emulsion fuels that have been emulsified and mixed with mineral oil and vegetable oil base fuels have been developed and commercialized as measures to prevent the sudden rise in petroleum, which is a limited reserve, and the global warming caused by exhaust gas during fossil fuel combustion ing.

  Emulsified mixing of water and oil is roughly classified into water-in-oil type mixing and oil-in-water type mixing. Most conventional emulsion fuel oils are in oils containing 20% or less of moisture in the fuel oil. There is almost no emulsion fuel with water-type mixing, high water content and stable water-in-oil mixing or oil-in-water mixing.

  Originally, since water has a large specific heat and is inert, when water is mixed in the fuel oil, the combustion energy of the fuel oil is lost to the water, and combustion becomes unstable. However, when emulsified and mixed with water that has been stably and uniformly refined, when the water mixed with the base fuel reaches the boiling point or higher, a steam explosion occurs and combustion energy is higher than when only the base fuel is burned. It is a well-known fact that

  However, in order to obtain the effects as described above, it is indispensable to emulsify and mix as much water as possible as fine water droplets in the base fuel oil in a stable state for a long time.

  However, most emulsion fuels currently being developed use additives such as special emulsifiers and surfactants to stabilize water and base oil in an emulsified state. Due to oxidative degradation and the use of a large amount of additives, fluidity has deteriorated and combustion energy cannot be obtained sufficiently. (Patent No. 3776188 and Patent No. 3103923). In particular, when initial mixing of water and base fuel oil is insufficient, it is difficult to obtain a uniform and stable emulsified mixed state even if stirring and circulating mixing are subsequently performed for a long time.

  Recently, the hydrogen bonds of water molecules are excited by resonant electromagnetic waves and electromagnetic field energy, etc., and the hydrogen bonds are separated by the resonant energy of the resonant electromagnetic waves, making the water clusters finer and promoting water vapor explosions. A method of using a flame retardant has also been developed, but water is activated and the surface activity is increased, so that it can be easily dissolved in oil.On the other hand, if the water content in a certain amount is exceeded, oil-water separation tends to be accelerated. There are cases where a large amount of sodium chloride or the like is added to prevent separation, but there is a concern about clogging of the distribution pipe due to precipitation of the sodium chloride solution. (JP 2008-45022).

Therefore, the present invention has been made in view of the above circumstances, and water is sucked into a pipe having base fuel oil as a basic fluid at a constant rate by the eductor effect, and stirred and mixed with a pump and a static mixer. Oil that is initially mixed efficiently and that flows into the lower part of the tank in the tangential direction of the cylindrical emulsion fuel oil generation tank, generates a vortex in the tank, and is initially separated by a specific gravity difference by centrifugal force. Repeatedly circulates and mixes the oil and water that is initially separated by sucking the separated water from the bottom of the tank and the separated oil from the center of the tank, and then passing through the pump and static mixer again, so that the base fuel oil and water are stable and uniform. It is an object of the present invention to provide a method of producing an emulsion fuel oil of water and a base fuel oil using water itself as a combustible agent.
Japanese Patent No. 3776188 Japanese Patent No. 3103923 JP2008-45022

  In order to solve such a problem, the present inventor makes the eductor effect suck the water mixed with the additive into the liquid having the base fuel oil as a base fluid on the suction side of the pump, and the pump and its discharge side. It was discovered that the initial mixing of oil and water can be stably performed by stirring and mixing with a static mixer. In addition, by letting the initially mixed oil water flow in the tangential direction of the circular tank, the initially mixed oil water is initially separated by the specific gravity difference separation due to the centrifugal force due to the vortex generated in the tank once. As a result, it was found that the water and the base fuel oil can be uniformly and stably emulsified and mixed by repeatedly circulating and mixing the initially separated oil water again with the above-mentioned pump and static mixer.

  That is, in order to solve the above-mentioned problems, the emulsion fuel oil production method of the present invention adds a plant-derived thickener such as carrageenan to water adjusted to a pH of 9 to 12 at a rate of about 1000 ppm, By increasing the viscosity, oil droplets are stably suspended and mixed in water, or water droplets are stably suspended and mixed in oil.

  Using the above method, water and base fuel oil with increased viscosity are stirred and mixed at a high shear rate with a static mixer, so that the water and oil particles are made finer, for example, the amount of water is increased to the same amount as fuel oil. In this state, an emulsion fuel oil in an emulsified suspension state that is stable for a certain time can be generated.

  In general emulsion fuel oil, water mixing in the emulsion is promoted by separating the hydrogen bonds with resonant electromagnetic waves or electromagnetic fields to make the water into the activated water with small clusters. It is said that water becomes a combustible and high combustion heat can be obtained. On the other hand, since the oil-water separation of the oil-in-water emulsion mixture becomes faster as the water cluster becomes smaller and activated, there is a problem that water can not be mixed in as much as the water-in-oil emulsion fuel. According to the present invention, by adjusting the viscosity of active water with a plant-derived thickener, the emulsion fuel oil in an emulsified suspension state that is stable for a certain period of time even when the active water is increased to approximately the same amount as the base fuel oil Can be generated.

  Furthermore, a general emulsion fuel oil has a problem of insufficient explosive power when used for an internal combustion engine and insufficient ignitability when used for an external combustion engine. Combustion of the emulsion fuel oil can be promoted by adding a small amount of the additive.

  According to the method for producing emulsion fuel oil according to the present invention, emulsion fuel oil can be produced efficiently at low cost using a small apparatus. Further, by using an emulsion fuel oil that is stably mixed with a base fuel oil with a high water content using water as a combustible agent, it becomes possible to reduce the generation of greenhouse gases, which is a major cause of global warming. Furthermore, the production and use of an emulsion fuel oil mixed with bioethylene makes it more effective in reducing greenhouse gases.

As shown in FIG. 4, the tangential flow of the tank 2 is caused to flow, and a vortex 18 is generated in the tank 2.

  The vortex 18 promotes initial separation due to the difference in specific gravity of oil and water, and the separated water accumulates at the center of the conical lower portion and the separated oil accumulates outside the center.

  In the above-mentioned thickening step of active water, the plant-derived thickening agent is uniformly dissolved in the active water by adjusting the pH of water to 9 to 12 in advance by an electrolysis treatment, a PH adjusting agent or the like.

  Further, the amount of oily additive is adjusted via the oily additive supply valve 16 from the oily additive tank 14 storing oily combustion accelerators such as commercially available engine oils and cetane number accelerators to the product oil tank 2. It is injected to improve the combustibility and explosiveness of the emulsion fuel oil as appropriate.

  The circulated and mixed fuel injected into the emulsion fuel oil production tank 2 is circulated through the static mixer 4 by the emulsion fuel oil transfer pump 3, and the emulsion fuel is uniform and stable for a long time by high-speed shearing by the mixer 4. Oil is supplied through an emulsion fuel oil supply valve 17.

  In this method of producing emulsion fuel oil, the valves for adjusting the flow rate are arranged as 5, 6, 7, 8, 9, 10, 15, 16, and 17, so that the optimum apparatus operating state can be obtained. . These flow control valves and the emulsion fuel oil transfer pump 3 can be automatically operated by remotely operating the raw water tank 1 and the liquid oil system signal installed in the emulsion fuel oil production oil tank 2.
