Description

Manufacturing method of highly efficient and polution free emulsion oil made from heavy oil and waste oil}

The present invention relates to a method for producing an emulsified oil having a high efficiency and a pollution-free function using heavy oil and waste oil, and more specifically, in mixing heavy oil such as bunker C oil, waste oil, waste cooking oil and the like, as an additive, an emulsifier, a staring agent And it relates to a method for producing a high efficiency and pollution-free emulsified oil by adding an oxidation promoter.

In general, as part of a fuel policy due to energy saving and pollution problems, a lot of efforts and research and development have been actively carried out to disperse low sulfur oil which reduces fuel sulfur content and to convert from solid fuel to liquid or gaseous fuel.

In particular, air pollution caused by petroleum fuels is focused on researching alternative energy and pollution-free fuel development with the launch of the WTO system and the new trade barriers of the OECD and Green Round (GR) from the existing viewpoint of damage to the ecosystem. This is insufficient.

The study of emulsified oils with water added to fuel oils began in Europe since 1950. Experiments have been conducted to improve fuel economy and combustibility by increasing the combustion efficiency of heavy fuels by using boilers and furnaces. In Japan, research on emulsified oil is being actively conducted.

At the time of World War II, water was added to aircraft gasoline to increase output, while research and experiment on emulsified oil reduced fuel, reduced soot, and increased combustion efficiency. There are research reports that can contribute to pollution prevention and energy saving.

The alternative energy is classified into solar energy, biomass, wind power, hydropower, fuel cell, coal liquefaction, gasification, marine energy, waste energy and other than coal, petroleum, nuclear power and natural gas. It is classified as a fluid fuel mixed with coal-based materials.

Among them, the waste energy refers to an oilification technique by pyrolysis of waste with a high energy content among combustible wastes generated at a workplace or a home, a manufacturing technique of a solid fuel, a combustible gas manufacturing technique by gasification, and a heat recovery technique by incineration. Renewable energy means the production of solid fuels, liquid fuels, gaseous fuels, waste heat, etc. through processing methods, which can be used as energy for industrial production activities.

Such waste energy can be commercialized in a relatively short period of time, and it can be said that there is a characteristic that the waste environment problem that threatens human right to live can be solved by utilizing waste resources as active energy resources.

In addition, waste alternative energy is ion-purified waste oil such as molded solid fuel (RDF) and automobile waste lubricating oil, which are solid fuels manufactured by shredding, separating, drying and shaping combustible waste such as paper, wood and plastic. Plastic pyrolysis fuel oil and flammable waste incineration heat recovery, which is a clean fuel oil produced by pyrolysing polymer waste such as waste oil refined plastic, synthetic resin, rubber and tires Four types of waste incineration, including steam production and power generation, cement kiln and iron ore kiln, are used.

Regarding the waste oil refined oil, which is one of the alternative waste energy, the amount of waste oil is estimated based on the sales volume of new oil, which is usually sold for application to automobiles or industrial fields. Since these waste oils are not consumable materials unlike general fuel oils, they can be used as useful resources, and thus, they have been studied for their efficient use.

However, these waste oils may contain heavy metal compounds such as Pb, Cd, Cr, Cu, Zn, chlorine compounds such as Cl and Br, sulfur compounds, etc. due to the decomposition or external pollution of their own oils. When exposed as it is, organic acid formation due to oxidation of waste oil can lead to ecological disasters such as soil degradation and groundwater contamination.

In addition to the waste oil, the treatment of waste cooking oil, such as waste cooking oil from the noodle factory, waste cooking oil from the cooking oil, waste cooking oil from the soap factory, and waste cooking oil from various fried or fried chickens, environmental and ecological It is a big problem in terms of science.

The present invention was developed to improve the above problems, in mixing 50 to 90% by weight of heavy oil, such as bunker C oil, waste oil, edible oil and 50 to 10% by weight of water, 0.1 to 1.5 in the mixture It is prepared by emulsifying by adding an additive to a weight percent, the additive is composed of an emulsifier, a coagulant, an oxidation promoter, the emulsifier is composed of a surfactant and an organic and inorganic alkali, the coagulant is a water-soluble metal salt and an organic amine It is made of zero and the oxidation promoter is composed of inorganic peroxide having a group of "-OO-" in the molecular structure, it is a new emulsified oil which is very efficient for energy saving and pollution prevention in the industrial field as well as fuel saving. In providing.

In detail, heavy oils such as bunker C oil, waste oil and waste oil are decomposed into fine particles as emulsifiers, and at the same time, the added water is ultra-fine granulated, and the fuel oil emulsified by the supporting agent and the oxidation promoter is burned. It is to provide an emulsified oil that can achieve economic benefits such as water combustion and water explosion to promote complete combustion by water gas reaction and microexplosion reaction, thereby preventing pollution, saving fuel, generating high-efficiency calories, and recycling waste resources.

Especially in pollution prevention, it is possible to prevent the generation of soot, dust, carbon monoxide, hydrocarbon, etc., and to reduce the excess air ratio, thereby reducing the conversion rate of SO2 to SO3, and the combustion flame is incandescent and radiant heat increases, which contributes to pollution prevention and fuel saving. To provide emulsified oil to recycle waste resources,

The idea of the technology of emulsified oil originated from Cheongsol-gabi (사용 松葉), which has been used as a fuel for winter in Korea in the past. This Cheongsol-gabi has about 90% water, and the remaining 10% is Songyu And other combustion organic materials, which have been used as fuels suitable for ondol heating because they have a very active combustion effect when placed under combustion conditions and have a very high thermal efficiency.

The emulsified oil is emulsified by applying the compounding process of the above-mentioned naturally occurring pine oil 10% and water 90% to heavy oil such as bunker C oil. Caustic Soda (NaOH) has the property of accommodating oil, and as an example, Blue Sol Gabbi with 10% oil in 90% water is well burned and has excellent thermal efficiency. However, when 50% of water is infiltrated into the completely dried pine needles and burned, the combustion is dead and no ignition occurs. The reason is that 50% of the water infiltrated into the dried pine needles is present as water to the last, and is not a water-soluble compound of oil and water existing in the above-mentioned blue pine.

In order to solve the problems of the prior art and the technical problem that has been requested from the past, the present invention is to use heavy oil, waste oil, waste oil as fuel oil, and to reduce the generation of air pollutants during combustion, By emulsifying the mixture with the additive of certain physical properties of the present invention, it is possible to significantly improve the combustion efficiency of fuel and to reduce the generation of air pollutants, and to provide an emulsified oil that can recycle waste resources.

It can be seen that the mixture of 50 to 90% by weight of heavy oil, waste oil, waste cooking oil and the like by using 50 to 10% by weight of water using the additive according to the present invention is not a non-combustible water.

That is, the molecular structure of the additive provided in the present invention includes both an lipophilic group and a hydrophilic group because it has an alkyl group moiety which is affinity for oil and a moiety that is easily affinity with water.

Therefore, since the additive of the present invention has a portion that is easily affinity for water and oil at the same time, the lipophilic molecules are arranged in the oil layer and the hydrophilic molecules in the water layer between the oil layer and the water layer. Accordingly, the surface active action of changing the properties of the surface and the surface of the water and the oil is promoted to achieve a stable emulsification.

In the emulsified oil according to the present invention, the water turns into fine water droplets (water droplets) of 10 microns or less in the oil, thereby bringing the water-in-water droplets or the oil-in-water droplets state. Emulsified oil vaporizes explosively as the water contained in the sprayed oil in the furnace is heated and expands to disperse the emulsion fuel in all directions and finely disperse to promote complete combustion.

In general, the ultrafine emulsified oil, which is completely different from the method of spraying water, increases the contact area with air, thereby reducing the excess air ratio to achieve rapid complete combustion.

In addition, the cooling effect of the flame by the latent heat of vaporization of the water and the action of water on the carbon to reduce the combustion carbon, and the chemical and physical action can reduce the content of soot and NOx and hydrocarbons.

The emulsified oil is in a colloidal state, i.e., a colloid, which makes fuel supply and injection very good.

When oil-in-water type oil is burned by a burner, the water contained in the oil droplets is heated at a high temperature to explode and expands rapidly, vaporizes. Finely scattered in all directions, causing a series of explosion reactions to achieve complete combustion.

Water droplets of emulsified oils are about 10 microns, and the water content is 10 to 30%, and many of the microns are contained in the remains. In other words, an emulsified oil having 20% moisture contains about 900 microdrops of water having a diameter of 3 microns if a single oil droplet is 50 microns in diameter.

In the case of L.P.G gas, the moisture content of the combustion gas is 19-20%, which is similar to that of emulsified oil. Therefore, the combustion efficiency of water-added emulsion oil is much higher than that of fuel oil.

The reaction of water is C + H 2 O → CO + H 2 → CO 2 + H 2 O, which is the reaction of water gas.

At high temperatures, water molecules and carbon in hot fuel oils react with water to form CO and H atoms. Therefore, carbon can be reduced and combustion efficiency can be increased.

Nitrogen oxides produced during the combustion of boilers are mostly NO and NO2, and both are called NOx. In the emulsified oil, the water contained in the fuel is uniformly atomized to suppress the formation of the local high temperature zone throughout the flame, and 20-30% of the water by volume ratio lowers the combustion temperature due to latent heat of evaporation. Water particles suppress the formation of NOx by acting as an endothermic action and a local high temperature prevention action by the carbon particles and water gas reaction. Pollution can be prevented by the NOx generation and combustion reduction method.

The emulsified oils according to the invention can reduce NO x production by 40 to 75% when used in boilers and industrial furnaces. In addition, due to the large surface area of the atomized remains, it is easy to contact the air, so even a small air cost can be burned, and there is a difference in the smoke reduction rate according to the structure and combustion of the boiler, but can reduce the smoke more than 50%. In general, when 50% of water is added, the concentration is reduced to about 1/2. The emulsified oil of the present invention can significantly reduce the generation of smoke so that contamination of the heat transfer surface is reduced, it is possible to reduce the fuel by about 30% by lowering the excess air ratio.

The flame of gas combustion of the emulsified oil of the present invention is burned with a transparent nonflammable salt, and the flame of heavy oil is a flame in which floating carbon particles are present as an opaque nonflammable salt shining yellow. However, the flame of emulsified oil is burned into a flame such as gas combustion with a gas-like flame.

When water is added to the fuel oil, the increase in the amount of combustion gas is increased by multiplying the water addition weight (kg) by 22.4 / 18 (Nm 3 / kg). When 30 to 50% of water is added based on the case where kerosene is burned at an air ratio of 1.2, the flame temperature is lowered by about 100 ° C. However, as the amount of combustion gas increases, the heat transfer effect does not decrease. In the combustion gas generated from burning liquid fuels (LPG, LNG), moisture is present about 13%. 50% of water is added to this, resulting in 16-17% moisture. In liquid fuel (LPG, LNG) combustion, moisture in combustion gas is generated up to 19-20%, but there is no problem of emulsified oil with water content similar to liquid fuel because there is no corrosion problem. There is a slight loss due to the added water, but rather the decrease of the air ratio, soot reduction and pollution of the heat transfer surface, the efficiency is increased to obtain the NOx suppression effect.

Emulsified oil is sprayed smoothly in the burner, and the ultra fine grained remains with the water are burned in a single flame to increase the combustion speed, and as the particles of water are exploded in series by high heat, the fuel is further atomized and redispersed. Combustion flames, such as microgas (GAS) combustion, form a complete combustion.

On the other hand, metal ions of the water-soluble metal salt of the components used as the supporting agent in the present invention is an inorganic material that is partially filled with 3d orbital (Orbital), so the oxidation stage is very diverse, and various materials constituting heavy oil, waste oil, waste cooking oil, and the like. It was found that the reaction can improve the properties of water-in-oil emulsified oil. This change in properties causes changes in chemical or physical bonds of the materials contained in the fuel oil, such as reactions with new metal cations produced by various oxidation reactions of metal ions and corresponding reduction reactions. It can cause a change in its physical and chemical properties.

At this time, since water is mixed with water-in-oil emulsified oils, new bonds such as formation of complexes between water and fuel oils and hydrogen bonds can be considered. Thus, emulsification is improved and experiments confirm that oil-water separation does not occur. Could.

In general, in acidic solutions, metal ions are easily reduced, but they are difficult to oxidize. However, the addition of the oxidation promoter of the present invention can enable the oxidation of metal ions.

That is, the pH of the solution containing a small amount of metal ions, water, and fuel oil is almost neutral, the metal ions are easily oxidized in the presence of the additive. If a metal ion is oxidized with an oxidation accelerator contained in an emulsified oil, the chemical bond of the oxidation accelerator will be broken and a new reaction will occur, whereby electrons (e-) emitted from the metal ion are emulsified oil. Some of these substances are reduced to cause chemical changes. In addition, metal ions continue to oxidize to provide many chemical changes due to oxidation reactions, and can be used as initiators of reduction reactions and chain reactions due to the release of numerous electrons. Therefore, the addition of metal ions causes constituents of emulsified oils to be chemically and physically changed. In this case, water-in-oil emulsified oils are mixed with water, resulting in new bonds such as direct bonds with water, formation of complex compounds or hydrogen bonds. As a result, the emulsification can be improved and thus, a long-term preservation can impart a stable effect that the oil can not be separated.

In the emulsified oil according to the present invention, in the mixing of 50 to 90% by weight of heavy oil such as bunker C oil, waste oil, and edible oil and 50 to 10% by weight of water, an additive is added so as to be 0.1 to 1.5% by weight in the mixture. It is prepared by emulsifying. The additive is composed of an emulsifier, a flame retardant, an oxidation accelerator, an emulsifier is composed of a surfactant and an organic and inorganic alkali agent, the flame retardant is composed of a water-soluble metal salt and an organic amine agent, and the oxidation accelerator is formed in the molecular structure of "-OO-. It consists of an inorganic peroxide having a group of ".

Emulsifiers are composed of surfactants and organic and inorganic alkalis, and surfactants are characterized by the ability to mix well with each other, such as water and oil, which has a hydrophilic functional group and a lipophilic functional group at the same time. have. There is a HLB (Hydrophilic Lipophilic Balance) value of each substance as a standard for distinguishing an emulsifier. Lower values give more oil-like properties, while higher values give more water-like properties. For example, the inherent HLB of bunker C oil, which is the most used heavy fuel for fuel, should be 4, but the HLB value of bunker C oil must be 4 to form an effective W / O type (water particle in oil) emulsion of combustion.

The emulsion produced by the addition of emulsifiers varies in form depending on the emulsification method. For example, an emulsion formed by adding a small amount of emulsifier to water is in the form of "Oil in Water (O / W), and an emulsion formed by adding a small amount of emulsifier to oil is" Water in Oil (W / O). In one embodiment of the present invention, the emulsifier is first emulsified with water to make an emulsion of O / W, which is then mixed with heavy oil to produce an emulsion of O / W / O form. This may cause the emulsion of the W / O / W form when the HLB value of the emulsifier to be used is adjusted. Since the form of the emulsion varies depending on the type and amount of the emulsifier used, the form of the emulsion emulsified by the present description is not particularly limited.
