Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mixes water with heavy oil, which is currently consumed in large quantities in each country as a cost-effective fuel, and burns the mixed oil of water and oil economically to reduce dust and NO. _{The present} invention is concerned with significantly reducing the amount of pollution such as _x and SO _x .

[0002]

2. Description of the Related Art Many conventional techniques for mixing and burning water with oil have been studied, but the following techniques are typical. A typical technique is to disperse water in heavy oil using a surfactant. This method has a drawback that water and oil are separated with the lapse of time, and smooth combustion cannot be performed as compared with combustion of heavy oil itself. For this reason,
It is mainly used for trial combustion and has not been adopted as a full-scale fuel oil for a long time.

Further, there are a method of injecting water into heavy oil at a high pressure and mixing and burning, a method of mixing water with oil and applying ultrasonic waves. These methods are also limited to short-time combustion in which a small amount of water is mixed with heavy oil and the oil is not separated, and the amount of soot, NO _x , SO _x is reduced as much as possible, rather than the economical efficiency of combustion. It is only used for the purpose. Moreover, when the combustion is continued for a long time, the inner wall of the boiler tends to rust, which is also a problem.

Further, a method has been proposed in which India ink is mixed with water, and the India ink water is added to heavy oil and burned. in this case,
It has been reported that oil and water are not separated, and the combustion efficiency is better than that of burning heavy oil alone.However, stable combustion is not obtained when the automatic combustion device burns, and troubles tend to occur. Is. It is expected that the ink water will settle to the bottom and the dispersion will become unstable.

[0005]

Under such circumstances, it is attempted to efficiently burn a limited oil fuel, and the amount of dust, nitrogen oxides (NO _x ), sulfur oxides (SO _x ) is increasing year by year. It is desired to reduce the generation amount of methane and use it as an environmentally friendly fuel. In the present invention, carbon is used as a core, and kerosene, hydrogen peroxide, a dispersant, sodium and the like are mixed with this to process an oil-based oxygen synthesis solution, which is dispersed and mixed in water, and the dispersed mixed water is put into heavy oil. By mixing and burning in a stable manner, stable combustion can be secured, and further, high temperature combustion that can not be expected with heavy oil alone can be achieved, and it is intended to raise significant economic merit and significantly reduce pollution generation. Is.

[0006]

It is considered that the combustion pollution of heavy oil is caused by an incomplete combustion element of heavy oil. However, the present invention uses carbon, an oily affinity material, an oxygen compound, as a means for complete combustion of heavy oil. A dispersant, sodium and the like are mixed and processed into an oily oxygen synthesis liquid, which is dispersed and mixed in water to form a mixed water of oxygen synthesis liquid and water, and this mixed water is mixed with heavy oil.

[0007]

According to the method for producing an oxygen-rich fuel oil of the present invention, (1) hydrogen peroxide is used as an oxygen compound, and this is mixed with heavy oil in a uniform and long-term stable state, Achieves easy combustion of heavy oil and complete combustion at high temperature, greatly improving combustion efficiency. Hydrogen peroxide was a liquid, expanded 1650 times by heating and vaporizing, became a minute gas, was fused and scattered with heavy oil, and was completely burned at a high temperature.
Even if the amount of this mixed hydrogen peroxide is small, it will permeate and fuse to all parts of the burning heavy oil by the action of the dispersant, and the simultaneous expansion and explosion of a large amount of mixed water will cause the high temperature complete combustion effect to the limit together with the scattered water gas. Raised to.

(2) As a means for fusing heavy oil with hydrogen peroxide uniformly and in a stable state for a long period of time to achieve complete combustion, carbon is used as a nucleus, and kerosene is mixed therewith, and the excess of oxygen is the basis. Mix hydrogen oxide. Hydrogen peroxide has a strong affinity for kerosene, water, and heavy oil, is stable, and expands 1650 times by heating and vaporizing, so even if the amount is small, it will promote the promotion of high temperature complete combustion. It works effectively.

(3) Kerosene has a strong affinity with carbon, hydrogen peroxide, and heavy oil, and also ignites at a lower temperature than heavy oil, and thus plays a role as a combustion improver for enhancing the flammability of heavy oil. Exerts effectively.

(4) The dispersant serves to rapidly and uniformly disperse fine carbon particles, kerosene, hydrogen peroxide and other synthetic liquids in water, and also disperse the water component mixed with the synthetic liquids into heavy oil. When the heavy oil and the surfactant water are conventionally mixed, there is no separation of water and oil, which tends to occur, and the mixed state is maintained uniformly and stably for a long time. Put mixed oil of water component mixed with synthetic liquid and heavy oil in a plastic container and store it in a warehouse. One is left standing and the other is repeatedly given a large vibration every certain period. rear,
After 12 months and 18 months, a visual check and a microscope check were carried out three times, but no separation of oil and water was observed, and the dispersion state was unchanged.

(5) Sodium hydroxide is a strong combustion aid for complete combustion of heavy oil, which causes a fine instantaneous explosion by heating, and combined with the effect of promoting complete combustion of kerosene, hydrogen peroxide, and water, the explosion of heavy oil. It promotes complete combustion by scattering more reliably.

(6) Water that mixes fuel oil in approximately equal amounts is the main role in achieving economic efficiency, complete combustion, and prevention of pollution.
The first of the mechanisms to completely accomplish the main task is to mix with carbon, kerosene, hydrogen peroxide, a dispersant, a synthetic solution such as sodium hydroxide. The water used for mixing is pure water, and the temperature is ideally 20 ° C. to 30 ° C. The mixing ratio may be 0.5% by weight or more of the synthetic liquid with respect to 100% by weight of water. In addition, mixing and stirring can be done manually or electrically.
It is sufficient that the dispersed state can be judged by visual inspection.

The second mechanism is the mixing of the first mixed water with the heavy oil, but this mixing needs to be carefully performed. First, heat the heavy oil to the range of 55 ℃ ~ 65 ℃, 50% heavy oil
The mixture is mixed under the conditions of the volume or more and the mixed water 50% or less, and the mixture is stirred using an electric propeller type agitator so that the heavy oil and the water can flow sufficiently in the vertical and horizontal directions. The stirring speed is 100 ~
Mix at 150 revolutions / minute, taking care to prevent air bubbles from entering. The mixing and stirring time depends on the volume, but requires 15 minutes or more.

(7) When the heavy oil of the oxygen-rich fuel oil that has been mixed and agitated in this way is burned in the boiler, the speed of ignition of the oil injected into the boiler is very fast,
A large and small oil and water explosion and splash flame in a boiler (Hakodate Boiler A-500 2 ton type) swirls violently, and the color of ordinary heavy oil flame is red-yellow and black smoke, while white-yellow flame. No smoke was observed with the naked eye.

As predicted from the combustibility of the boiler,
Ignition speed of oxygen-rich heavy oil, rapid high-temperature combustion, and black smoke-free combustibility are exhibited by a mixture of kerosene, hydrogen peroxide, sodium, water, etc. Is dispersed in heavy oil together with a dispersant, and is mixed and mixed with heavy oil to form a new fuel oil in a uniform and stable state without separation and release, and

During combustion in a boiler, the combustion temperature of heavy oil is usually about 1100 ° C, whereas the combustion temperature of oxygen-rich heavy oil produced by mixing mixed water and heavy oil is as high as 1480 ° C. , Complete combustion was observed. This is because the liquid containing hydrogen peroxide and water as the main ingredients is 1650 times the moment when it vaporizes by heating into a gas.
Due to the explosion phenomenon, it is thought that the main cause is that it becomes ultrafine particles and scatters with the heavy oil composition, complete combustion, and high temperature.

(8) The weight ratio% of each drug in the oil-based oxygen synthesis liquid is 1% of carbon black and 44 of the oil-based affinity agent.
%, Oxygen compound 40%, dispersant 10%, sodium 5%
Mix and process by. All of these materials are commercially available, and their handling is less dangerous and simple,
Easy to disperse and mix with water and heavy oil. In addition, the mixing ratio of the oil-based oxygen synthesis solution and water is 200
The ratio is as follows, and the mixing ratio of the mixed water obtained by mixing the synthetic liquid and water and the heavy oil can be made substantially equal.

The oxygen-rich fuel oil produced by mixing as described above is an oil containing water in an amount equal to that of heavy oil,
By fully burning at higher temperatures than regular oil, its economic effect was over 30% as measured in test burning. Also, due to high temperature complete combustion, soot and dust generation amount, NO
_The amount of _x and SO _x generated is 30 each compared to normal oil.
A decrease of more than% was confirmed, and it was confirmed that the contribution to economy and social environment was extremely large.
