Abstract

PROBLEM TO BE SOLVED: To form a more stabilized emulsion by rendering drops of water dispersed in an oil finer than in the past and further to apply this to the improvement on the combustibility of a fuel. SOLUTION: By quickly condensing fine bubbles of steam mixed in an oil by cooling to form fine drops of water and, at the same time, shattering the fine drops of water as such having been formed by condensation with ultrasonic waves to be generated by quick reduction in volume when condensed, fine drops of water are dispersed in a stabilized state into oil. When this emulsion is jetted or sprayed as the fuel into a combustion chamber, drops of oil in the state of covering the fine drops of water with the oil film are formed, and the fine drops of water in the drops of oil are quickly vaporized by the heat of combustion to explosively shatter the drops of oil from the inside, and accordingly the drops of oil becomes burnt in the form of fine articles to the cores, and the efficiency of combustion is improved and, at the same time, injurious components to be accompanied by incomplete combustion cease to be generated.

The supply of steam to the oil is performed, for example, by stirring the oil in a stirring vessel while cooling the oil, inserting the tip of an air supply pipe provided with a number of fine holes into the oil, and blowing high-pressure steam. Done. The temperature of the water vapor may be a temperature at which water turns into a gas, and is selected, for example, from 105 to 120 ° C. It is desirable that the hole at the end of the air supply pipe be as small as possible in order to disperse the water vapor in a fine bubble state,
The diameter is selected to be, for example, 100 μm or less. The oil is agitated in order to make the water vapor finely foamed and uniformly dispersed, and it is desirable to vigorously agitate at least only the part where the water vapor is blown.

The oil is cooled in order to condense the water vapor and return it to water. The oil may be at room temperature as long as the oil temperature is lower than the boiling point of water. Advantageously, the condensation takes place rapidly. Therefore, for example, in a location condition where the heat of vaporization of natural gas can be used, it is very effective to use this. If sufficient cooling is possible as described above, steam may be directly blown into this pipeline while cooling the pipeline through which oil passes without using a container as described above. In addition, the supply of water vapor to the oil should be performed by means such as supplying water vapor into the fuel oil by applying the principle of atomization, for example, without passing through fine holes or blowing under pressure as described above. You can also. In this case, the steam may be a reduced-pressure steam of less than 100 ° C. For example, if the flow rate of the oil is increased to make the Venturi negative pressure lower than the pressure of the steam, the steam can be sufficiently supplied.

[0013] The water vapor thus mixed with the oil is rapidly cooled by the surrounding oil and condenses, but the volume of the water vapor is approximately 2,000 times the volume of the water. Accordingly, the condensation causes the water vapor bubbles to become fine water droplets having a volume of about 1/2000. At this time, a large and sharp reduction in the volume generates strong ultrasonic waves, and the water droplets generated by the condensation generate the ultrasonic waves themselves. It is exploded by sound waves to produce fine water droplets having a diameter of about 3 μm. Since such fine water droplets are fine particles which are stably present by causing Brownian motion, a water / oil emulsion which is stable for a long period of time without separation of water and oil can be obtained.

The above example is an example in which fine steam bubbles are externally supplied into oil as a means for obtaining oil in a state in which fine steam bubbles are mixed. It is also possible to generate such fine steam bubbles in the oil and mix it with the oil. That is, in the first example, for example, oil and water are put into an emulsification tank and stirred at high speed to disperse water droplets in the oil. In this state, the particle size of the water droplet is still quite large, but when the oil containing the water droplet passes between a pair of electrodes facing each other with a small gap, the water droplet contacts both electrodes and a large current flows. As a result, the water droplets evaporate to become steam, and the oil is mixed with fine steam bubbles. Thereafter, as in the case of supplying water vapor from the outside, the water vapor bubbles are cooled by the surrounding oil and condensed instantaneously, and at this time the large and rapid reduction in volume generates strong ultrasonic waves. The water droplets generated by the condensation are exploded, and fine water droplets are generated.

Further, for example, an oil and a small amount of catalyst powder such as platinum are put into an emulsification tank and stirred while cooling, and oxygen gas and hydrogen gas are separately blown into this from an air supply pipe provided with many fine holes. . As a result, oxygen and hydrogen react with each other on the surface of the catalyst to generate steam, and a state is obtained in which fine steam bubbles are mixed in the oil. Thereafter, as in the case of supplying water vapor from the outside, the water droplet itself generated by cooling and condensing is exploded by ultrasonic waves, and fine water droplets are generated.

The oil-type emulsion is supplied to the combustion chamber by injection or spray so as to be supplied to the combustion chamber as fine oil droplets. As a result, fine oil droplets in a state in which fine water droplets in the emulsion are covered with an oil film are generated, and the fine water droplets in the oil droplets are rapidly vaporized by the heat of combustion and explode the oil droplets from the inside. . For this reason, the oil droplets are in a state of fine particles and completely burn up to the core.

Therefore, the combustion efficiency is improved, and no harmful components such as black smoke and HC are generated due to the incomplete combustion. Further, the combustion temperature is reduced due to the contained water, and the generation amount of NOx is also reduced. As a result, it is possible to reduce fuel consumption and purify exhaust gas, and to meet the social demands of preventing air pollution and saving petroleum resources. Further, if edible oil waste oil is emulsified using a dispersion medium as a dispersion medium, harmful components such as black smoke and HC due to incomplete combustion are not generated, and incineration disposal with a small generation amount of NOx can be performed.

It was reduced by 0%, the black smoke component in the exhaust gas could be reduced by about 70%, and the NOx could be reduced by half. In addition,
At the time of combustion, fine water droplets contained in fuel oil evaporate and expand, and the amount of energy generated increases accordingly,
By including a large amount of water, it is possible to obtain a fuel with a large output, and if this is applied, the actual fuel is mainly used for vaporizing water, and the mechanical output is mainly generated by the contained water. It is also possible to realize a new internal combustion type steam engine.

The improved combustion efficiency and the elimination of harmful components such as black smoke associated with incomplete combustion can be eliminated, reducing fuel consumption and purifying exhaust gas. It is possible to meet the demands.

According to a third aspect of the present invention, there is provided a method for producing a water / oil emulsion, wherein fine water vapor bubbles mixed in oil are rapidly cooled and condensed to form fine water droplets, and the volume of the condensed water is reduced. Ultrasonic waves are generated by rapid shrinkage, and the fine water droplets generated by condensation by this ultrasonic wave are crushed to produce finer fine water droplets, so that the fine water droplets are dispersed in oil in a stable state. To obtain a water / oil emulsion. Therefore, the water droplets are extremely finely divided, and a long-term stable water / oil emulsion which cannot be achieved by the conventional technique using a surfactant can be obtained. Thus, the water / oil emulsion of the first invention can be obtained. Becomes possible.
