Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to fuel oil, and more particularly to a fuel oil mixed with oil and water and a method for producing the same.

[Conventional technology]

Heavy oil or the like is used as the fuel oil for -g.

However, heavy oil generates black smoke during the combustion process and is difficult to burn completely, and alternative fuels are desired because of the environmental pollution caused by the generation of harmful gases and other costs associated with combustion.

As one of the methods, a method of mixing water and oil at a predetermined ratio and burning the mixture has been attempted. This is a method in which heavy oil is combusted in a burner, and steam or spray water is blown into the flame of the residue burner when the inside of the furnace reaches a predetermined temperature. Although experimental, a method has also been attempted in which an internal combustion engine is started with gasoline, and then spray water is gradually supplied to the carburetor and mixed with vaporized gasoline.

(Problems to be solved by the invention) However, in all of these systems, water and oil are stored in separate tanks, which requires time and effort to operate, and it is difficult to reliably thermally decompose water. There is a problem.

One possible solution to this problem is to completely mix oil and water. Conventionally, conventional methods of mixing oil and water include storing oil and water at a certain ratio in a container and stirring with a stirrer, or using ultrasonic waves, but in either case, it is difficult to form and maintain a perfect colloidal state. It is difficult, and sometimes there are problems such as gelation and hardening.

There is also a method of using an inorganic surfactant as a ponding agent. However, even with this method, it is difficult to obtain a stable colloidal state.

In all of these cases, it is thought that the hydrophobic oil colloid particles do not mix with water, and the traction force between the oil colloid particles is superior, causing the particles to grow into large-diameter particles.

[Means for solving problems]

The present invention covers hydrophobic oil colloid particles produced in view of the above points with hydrophilic colloid particles, thereby preventing the growth of the oil colloid particles and promoting the thermal decomposition of water by the medium that forms the hydrophilic colloid particles. The fuel oil of the first invention is made by adding an organic hydrophilic medium to water to form a colloidal solution, and this colloidal m
It is characterized in that oil is mixed into the liquid in the form of a colloid, and the hydrophobic colloid particles of the ura are coated with the hydrophilic colloid particles of the medium.

The second invention relates to the above method for producing fuel oil, which is characterized by adding a predetermined ratio of an organic hydrophilic medium to water and having an adhesion property to oil to produce a colloid m.
The purpose is to form a liquid solution, and then mix and stir the colloidal solution and oil to make the oil into a colloid and to coat the hydrophobic colloid particles of the oil with the hydrophilic colloid particles of the medium.

[Effect]

Due to the intervention of hydrophilic colloid particles, oil colloid particles do not adhere to each other and grow. In addition, the thermal decomposition of water is promoted by the medium.

〔Example〕

Figure 1 shows the first stage of fuel oil production for carrying out the method of the present invention.
It is a process flow sheet of an example.

In this embodiment, the produced fuel oil is immediately supplied to the burner of the boiler, and the tifLfa equipment 1 includes an oil tank 2, a water tank 3, a medium storage tank 4, and a mixer 5. The oil tank 2 has a heater 6 and a concentration controller 7.
In addition, each of the medium storage tanks 4 is equipped with a heater 8,
A stirrer 9 is provided in the water tank 3. However, it is heated! IS
, 8 are used when it is necessary to lower the viscosity, such as when the viscosity increases in winter, and are not necessarily required.

10, 11, and 12 are pumps, 13, 14, and 15 are flowmeters, and 16.17 is a flow rate recording controller.

In the above configuration, a predetermined amount of water is first supplied to the water tank 3 by the pump 10, and then a predetermined amount of the medium is supplied to the water tank 3. This medium has hydrophilicity and surrounds oil molecules, that is, it has hydrophilicity or adhesion, and furthermore, a medium that promotes thermal decomposition with respect to water is used.The present inventor has conducted various studies on this point. Polyvinyl alcohol (hereinafter referred to as P)
It has been discovered that an organic medium containing enzymes extracted from fruit (e.g. pineapple) is optimal.

As is well known, PVA has a low solubility in water and has a colloidal shape, although its molecular weight varies depending on its size.

Further, although its effect on colloidal oil particles is not clear, it is thought to have the effect of surrounding the oil particles at the water surface that comes into contact with the oil particles. Further, the above medium was found to be effective in accelerating the thermal decomposition of water as a result of experiments, and this is thought to be due to the effective action of extracted fruit enzymes.

Next, this medium aqueous solution (the medium is contained in a colloidal form) and the oil from the oil tank 2 are respectively transferred to the flow rate recording controller 1.
6. While measuring in step 17, a predetermined ratio is supplied to the mixer 5, and both are stirred and mixed. This causes the oil to form a colloidal fuel oil of the present invention in an aqueous medium solution. As mentioned above, these hydrophobic oil colloid particles are covered with the hydrophilic colloid particles of the medium, and by continuing stirring, the miniaturization of the hydrophobic oil colloid particles is promoted, and even if left standing, the oil colloid particles are not separated from each other. It is blocked by the film formed by the medium colloid and does not grow in contact with it, maintaining a stable dispersion state.

The fuel oil of the present invention produced by the mixer 5 can be ignited and combusted by ordinary means, and is supplied together with pressurized air to the burner 22 of the boiler 21 via the supply pipe 20, where it is combusted.

The results of the total calorific value of the combustion experiment are shown below. However, 40%
The W product contains 40% water dissolved in the above medium, 60% C heavy oil, and 5
The 0% W product is a mixture of 50% of the above medium aqueous solution and 50% of CfK oil, and for comparison, the combustion results of C heavy oil alone are also shown.

From this test result, it is inferred that the fuel oil of the present invention not only burns heavy oil well, but also partially thermally decomposes and burns the water.

Next, Figure 2 shows the process flow sheet of the second embodiment, and the manufacturing equipment of the six embodiments! ! 30 is provided with a mixing tank 31 (in place of the mixer 5 in the previous example), and this mixing tank 31 is equipped with an agitator 32. The other parts are the same as in the previous example, and the same parts are given the same reference numerals and explanations will be omitted.

In this example, the mixing tank 31 also serves as a storage tank, and the oil colloid particles will not grow even if the fuel oil of the present invention is left for a long time.

Next, FIGS. 3 and 4 show other examples of the mixer.

It is undesirable for the mixer 5 and the mixing tank 31 to produce air bubbles during agitation, since fuel oil is a colloidal solution and it is difficult to release air bubbles.

The mixer 40 shown in this example includes a tank 41 and a pump 42, and the tank 41 has a plurality of suction pipes 43 evenly distributed in the circumferential direction, and a discharge pipe 44 at the lower center.

45 is a medium supply pipe, 46 is a water supply pipe, 47 is an oil supply pipe,
48 is a discharge pipe, and 49 is a drain cock.

First, a predetermined amount of water is injected into the tank 41, a predetermined amount of medium is injected into the tank 41, and a predetermined amount of medium is injected into the tank 41, and the pump 42 is operated to suck the water from each suction pipe 43 and blow it up from the discharge pipe 44 for stirring.

However, the blow-up should be as weak as possible to prevent air from getting mixed in.

Inject heavy oil that has been stirred and mixed for a specified period of time, and stir and mix in the same manner. As a result, it is possible to obtain the fuel oil of the present invention, which is a mixture of colloidal water-oil that does not separate and remains stable for a long period of time.

Although the above embodiment shows an example in which the generated fuel oil is directly supplied to the burner, it can also be packed in a container and used in the same manner as ordinary oil.

〔Effect of the invention〕

As described above, according to the present invention, a hydrophilic vegetable medium is dissolved in water to form a colloid, and the hydrophobic oil colloid particles are coated, so that the oil colloid particles do not grow and form a stable colloid. can be maintained.

In addition, since oil is in a colloidal state, it has a large surface area and is easily ignited, and enzymes contained in the medium have multiple effects such as promoting the thermal decomposition of water.
