Description

  The present invention relates to an emulsion of water and oil, and more particularly, to provide an emulsion composition effective as a fuel for an engine and an emulsification apparatus thereof.

  Conventionally, it has been known that it is effective to mix some water (referred to as emulsion fuel) into the fuel as a technique for improving the combustion efficiency of the fuel or reducing harmful components in the exhaust gas. . However, in the conventional technology, even when a stabilizer such as a surfactant is used, water droplets mixed in the fuel oil are relatively large. For this reason, oil and water are often separated during transportation and storage, and when emulsion fuel is injected into a combustion chamber such as an engine, the oil droplets and water droplets are separated. It is difficult to completely burn, and it is impossible to suppress generation of harmful components such as unburned components, and high combustion efficiency cannot be obtained.

  As described above, the emulsion fuel is a fuel obtained by adding water to various combustion oils and dispersing the water in the oil. As described above, the emulsion fuel itself is not stable over time as an emulsion. In other words, the emulsion fuel, which is just dispersed in water with fine particles of water, will eventually aggregate to separate the oil into the upper phase and the water into the lower phase and the two phases. It is no longer possible to use it as fuel. Therefore, it is necessary to ensure dispersion stability during transportation and storage.

  In order to ensure the stability over time, Patent Document 1 proposes to reduce the particle diameter of dispersed water particles (Patent Document 1). For this purpose, it has been proposed to add a stabilizer (Patent Document 2).

Japanese Utility Model Publication No. 58-055331

  However, the former technique that only reduces the size of the water particles does not change the fact that the particles are simply dispersed, and the oil-water two-phase separation also occurs over time. And it will be very difficult to return to the original dispersed state after oil-water two-phase separation. Accordingly, there is a difficulty that such emulsion fuel is difficult to apply to diesel engine fuel.

  On the other hand, although the latter technique for adding a stabilizer is improved in stability as compared with the former, there is a drawback that the fuel cost increases due to the addition of the stabilizer. Further, it has been pointed out that when an emulsion fuel is used as a diesel engine fuel by adding a stabilizer, the engine and the intake / exhaust system are likely to decay.

  In the present invention, water droplets dispersed in oil are made finer than before to form a more stable emulsion, and this is applied to reform fuel to improve combustibility and to reduce harmful waste. The purpose is to cause combustion.

  1st of this invention is related with the manufacturing method of the emulsion composition of water and oil, and supplies the water and oil in the stirring means, and is the ozone bubble made into the fine bubble supplied from the bottom part of the stirring means. Water and oil are stirred, water and oil in the stirring means are sequentially refined through water and oil molecule refining means, and the water and oil molecules are refined into the stirring means. This is a production method characterized by producing an emulsion composition in which fine water and oil molecules are combined by ozone by refluxing and repeating such operations.

  1st invention WHEREIN: The ratio of the water and oil supplied in a stirring means provides the manufacturing method of the emulsion composition which is 5-30: 100 weight part.

  A second aspect of the present invention relates to a water and oil emulsification apparatus, comprising a water tank, an oil tank, an ozone generator, and a stirring tank, wherein the water tank and the oil tank are provided with flow paths. In the emulsification apparatus that connects the ozone generator and the stirring tank via a flow path, and makes water and oil into an emulsion composition while supplying ozone in the stirring tank. An agitation tank is equipped with an ozone microbubbler, and ozone is passed through water and oil as fine particles to stir both, and a water and oil molecule refiner is connected to the agitation tank via a flow path. The apparatus is characterized in that the refined water and oil molecules are connected in a flow path so as to return to the stirring tank.

  In the second aspect of the present invention, it is preferable to adopt a means for refluxing the refined water and oil molecules into the stirring tank by a sprinkler, and the ozone microbubble generator is 0.3-1. It is preferable to provide a large number of holes having a diameter of 0 mm, and to stir the water and oil through the holes, with the ozone becoming fine particles. A water sensor may be provided in the stirring tank or the flow path, and a device that emits a signal when the water sensor does not detect moisture can be used.

  Since the emulsifying apparatus according to the second invention is configured as described above, water and oil are stirred by fine bubbles of ozone in the stirring tank to become a mixture of emulsion liquid, water and oil, and thereafter Then, it is supplied again into the agitation tank through a water and oil molecule refining device (hereinafter referred to as a molecular refining device). This action is repeated to complete the emulsification of oil and water.

  If such an apparatus is used, a predetermined amount of water and oil can be completely emulsified, and for example, effective utilization of a low-quality oil emulsion can be facilitated.

  In this type of emulsification in the prior art, a water tank, an oil tank, and an ozone generator are provided in a stirring tank, and water and oil are emulsified while supplying ozone by operating the stirrer in the stirring tank. There is technology (Patent Document 3).

JP-A-60-231794

  However, it can be said that such emulsification is merely agitation of water and oil with ozone. Therefore, the disadvantage of being easily separated into two phases of water and oil cannot be removed, and it is effective as an emulsion liquid. It had the disadvantage of being difficult to use.

  The main object of the present invention is to provide a method for producing an emulsion composition having high dispersion stability over time and low pollution of combustion exhaust gas, and an emulsification apparatus (Daishin Green Eco Power).

  Hereinafter, the first feature will be further described focusing on the first invention. The first feature is to stir water and oil with fine ozone bubbles, and the second feature is a means for refining water and oil molecules (hereinafter referred to as molecules). This is in connection with this to obtain a more effective emulsion composition.

The action of applying molecular refinement means has not yet been fully elucidated, but the inventor has inferred as follows. That is, these molecules are refined by molecular refining means to bring about activation. In particular, water molecules undergo weak electrolysis, and the resulting hydroxide ions (OH ⁻ ) are combined to form hydroxyl ions (H ₃ O _2). ^- ) Occurs, and the oily carbon molecules are repeatedly decomposed by intermittent intermittent discharge. In such a state, stirring is applied by the fine bubbles of ozone, and the ozone is combined to form a complete emulsion state. Therefore, when this is used for fuel, it is considered that a better combustion state is obtained even in a low oxygen state.

  As the molecular refining means, for example, each means such as ultrasonic decomposition, electrolysis, magnetic decomposition, forced stirring decomposition and the like is selected.

  In the second aspect of the present invention, it is preferable to adopt a means for uniformly recirculating the water and oil molecules that have passed through the molecular refining device in a stirring tank by a sprinkler.

  Stirring in the agitation tank is carried out with bubbles of ozone. However, in order to refine the ozone, ozone is introduced into a box housed in the agitation tank, and a large number of 0.3 to 1.0 mm diameters are introduced into the box. This is done by providing a hole.

  A water sensor may be provided in the stirring tank or the flow path, and a device that emits a signal when the water sensor does not detect moisture can be used.

  Oils used in the present invention include light oil, A heavy oil, B heavy oil, C heavy oil, kerosene, gasoline, and other oils such as edible oils. A good emulsion will be obtained.

  Water added to the above oil as an emulsion is 5 to 30 parts by weight, preferably 10 to 20 parts by weight, based on 100 parts by weight of the oil.

  Speaking of the obtained emulsion composition, it is an emulsion in a complete state of oil and water. For example, when an emulsion of (light oil + water) is used as a fuel in a diesel engine, the exhaust gas becomes clean and at the same time the output of the engine Has the effect of high output.

  That is, by compressing the air sucked by the engine to a high pressure, the air in the cylinder becomes high temperature, and the light oil blown by the injection pump is ignited in the engine cylinder and the moisture in the light oil becomes high temperature. Since the amount of hydrogen and oxygen increases as a whole by being decomposed into hydrogen and oxygen, combustion becomes more complete. For this reason, the exhaust gas is greatly reduced as the output increases, and furthermore, the engine noise becomes very quiet and the output of the low-speed rotation is increased due to a decrease in engine knocking during idling. There is.

  Hereinafter, the second invention will be further described. FIG. 1 is a conceptual diagram centering on the fluid flow of the emulsification apparatus according to the second invention, FIG. 2 is a side view of the emulsification apparatus, and FIG. 3 is a plan view. Indicates.

  In the figure, reference numeral 1 denotes an emulsifying device, which includes a water tank 2, an oil tank 3, an ozone generator 4, and a stirring tank 5. The water tank 1 and the oil tank 2 are connected to the stirring tank 5 via a flow path 6a, and the ozone generator 4 is also connected to the stirring tank 5 via a flow path 6b. And it is the emulsification apparatus 1 which makes water and oil into an emulsion composition, supplying ozone (fine foam) in the stirring tank 5.

  The water tank 2 and the oil tank 3 are connected to the agitation tank 5 via opening / closing valves 7a and 7b and flow meters 8a and 8b. In this example, the flow path 6a merges on the downstream side of the flow meters 8a and 8b and is connected to the stirring tank 5. Each meter 8a, 8b is for measuring each quantity based on the desired mixing ratio of the emulsion.

  The ozone generator 4 is connected to the ozone microbubble device 10 in the agitation tank 5 through a compressor 9 through a flow path 6c. In this example, the ozone microbubble device 10 is arranged in a cross shape at the bottom of the stirring tank 5, and a flow path through which ozone flows is formed, and a number of holes connected to the flow path are formed. 11 is provided. The ozone introduced into the agitation tank 5 is blown into the agitation tank 5 from the numerous holes 11 as fine bubbles, and is used for agitation of water and oil. Therefore, the smaller the ozone bubbles, the larger the contact area. Therefore, it is preferable that the size of the holes 11 for forming the bubbles is a hole having a diameter of 0.3 to 1.0 mm.

  The bottom of the agitation tank 5 is connected to the lower end of the molecular refiner 13 through a circulation pump 12 by a flow path 6d. From the upper end of the molecular refiner 13, a sprinkler 14 provided at the top of the agitation tank 5 is connected. linked. That is, water and oil in the stirring tank 5 are pumped from the bottom to the molecular refining device 13 by the circulation pump 12, and the water and oil that have passed through the molecular refining device 13 are supplied into the stirring tank 5 in a spray form. Will be passed through the circulating circuit. In this example, the molecular refining device 13 exposes water and oil to magnetism, and brings about weak electrical decomposition particularly against water. Since this effect has already been described, a description thereof will be omitted.

  As described above, since the present invention does not use an emulsifier such as a surfactant in the emulsification step, it is not affected by the surfactant or the like even when the obtained emulsion composition is used. .

  Needless to say, a water sensor may be provided in the stirring tank or an appropriate flow path so that a signal is generated when the water sensor does not detect moisture. If water is present, water, oil, and the emulsified composition will be circulated further. When the water sensor does not detect moisture, the completion of the emulsification is notified. As an example of this water sensor, the presence or absence of moisture is determined by measuring electrical conductivity. The cock 15 in the figure is for taking out the emulsion composition.

Next, the emulsion composition will be described. 4 liters of water is emulsified in 40 liters of light oil. In the apparatus 1 shown in FIG. 1, the internal pressure of the stirring tank 5 was 3 kg / cm ² , the generation of ozone was liter / hour, and the size of the hole 11 of the ozone microbubble device 10 was a diameter of 3 mm. The molecular refinement device 13 was a magnetic decomposition type, and its strength was 96000 gauss. The apparatus 1 was continuously operated for 1 hour. The resulting emulsified composition was 44.2 liters.

  Table 1 shows the analysis results of the resulting emulsified composition and light oil before treatment. By using water as an additive to be added to the oil, the cost is low and the amount of oil contained in the oil is increased. As a result of the experiment, an increase of 10 to 20% with respect to the original oil is expected. Considering the sulfur content, it was present in the range of the second minority before emulsification, but its unit decreased to the third minority because of the emulsion. When this is used as fuel, the harmful substances in the exhaust gas are significantly reduced.

  Of course, it does not separate into water and oil even if left for a long time, does not freeze even at low temperatures (−30 ° C.), further increases output during driving, and saves about 15-30% in fuel consumption. There are features such as.

  In the emulsifying device according to the second invention, water and oil are stirred by fine bubbles of ozone in the stirring tank, and the water and oil molecules are activated by the molecular refining device. Is repeated to complete the emulsification in which water and oil do not separate even when left for a long period of time. And if the emulsified composition obtained by such an apparatus is used as a fuel, exhaust gas is reduced and the output during running is increased, so that fuel consumption can be saved, and its use range is extremely wide.
