    A method of reproduction of waste oil and an apparatus used therefor}
    [20] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for regenerating waste oil, such as waste cooking oil or animal fats and oils, and more particularly, in order to be used in diesel engines or diesel oil boilers. The method of regenerating waste oils such as waste oil or animal fats and oils to improve waste oils with high viscosity and to reduce the viscosity to be suitable for diesel engines or diesel boilers, and to make fuel particles finer to improve the combustion efficiency. And to the apparatus.
    [21] As used herein, the term "waste oil" is not a commonly used "industrial waste oil," but is relatively viscous relative to industrial oils such as waste cooking oil or animal fats emitted after use in homes, restaurants, food processing companies, and the like. It refers to waste oil or waste oil.
    [22] In recent years, the consumption of fried cooking oil is increasing as the consumption of fried foods (potato chips, french fries, friedchicken, etc.) increases. The waste cooking oil (waste oil generated by plants, oils, etc.) is the main culprit of river pollution because BOD demand is about 1 million ppm higher than 35,000ppm of doenjang stew and 200,000 times higher than 5ppm where fish can survive. . In order to prevent the above-mentioned river pollution, a method of regenerating waste oil and recycling the fuel for a diesel engine or a boiler has been proposed.
    [23] In the conventional method of regeneration of the waste cooking oil into fuel, in Korean Patent Application Laid-Open Publication No. 99-16815 (published date, 1999. 03. 15.), in the "automotive fuel supply apparatus using the waste cooking oil and its fuel manufacturing method", In the fuel manufacturing method, the waste oil refined by a filter is dissolved in an organic solvent, followed by esterification by adding an alcohol including water, and the solution obtained by the esterification is allowed to stand for a predetermined time, and the upper portion of the organic layer and the lower portion of the water layer. Removing the lower layer which is the aqueous layer, injecting water into the upper organic layer, dissolving the remaining water-soluble substance in water, rinsing several times, and then separating the lower layer to remove the lower layer which is the aqueous layer. It consists of obtaining monoesters that can be used as automobile fuels by distilling nucleic acids according to the difference between break points in the refiner.
    [24] By removing the water-soluble substances by the esterification method of the waste oil of the high viscosity component to improve the properties of the fuel to a state close to diesel, to prevent contamination while reducing the cost of disposal of waste oil, using raw materials obtained from waste oil It is known to provide the effect of import substitution and to reduce the harmful components such as soot to prevent environmental pollution.
    [25] However, in the conventional fuel regeneration method using waste cooking oil, excessive wastewater is generated by injecting a large amount of water to dissolve the water-soluble substance remaining in the organic layer of the separated upper layer in the solution obtained by esterification in water. There are disadvantages of increased water cost and the need for separate purification facilities. In addition, when the water-soluble material remaining in the organic layer is separated again through the injection of water, and the organic layer from which the water layer is removed is directly used as a fuel, corrosion of the equipment is caused by the remaining organic solvent and water. The process and apparatus for obtaining monoesters that can be used as automobile fuels by separating nucleic acids by the difference between the loading and breaking points must be complicated and expensive equipments must be installed.
    [26] In addition, Korean Patent Application Publication No. 99-70659 (published date, September 15, 1999) discloses a method for regenerating waste fuel and regenerating the waste oil. The present invention relates to a method and apparatus for regenerating a diesel fuel by raising a negative potential of a molecule by acting and activating it, which merely lowers the viscosity of waste oil suitable for a diesel engine. In addition, since the waste oil having a low viscosity is filtered by a conventional filter, there is a risk of damaging the engine and environmental pollution due to incomplete combustion.
    [27] And, Republic of Korea Patent Publication No. 99-79052 (published date, 1999. 11. 05.) "recycling treatment method and apparatus of waste cooking oil" to remove the impurities using a filter after the addition of alkaline substances as methanol and catalyst After esterification, free alkali and debris are removed by natural precipitation, and water is mixed to separate methyl ester and glycerin. And finally, by heating to a predetermined temperature to evaporate the water, and through the purification process to make a fuel. However, high-viscosity waste cooking oil is filtered with a conventional filter, and impurities are still remaining, and depending on natural phenomena such as esterification, separation of methyl ester and glycerin, and purification process, the processing time becomes long.
    [28] The present invention was devised to solve various problems of the conventional method for regenerating fuel using waste oil such as waste cooking oil and animal fats and oils, and to lower the viscosity to be suitable as a fuel for diesel engines and boilers, harmless to the environment, and combustion efficiency. It is an object of the present invention to provide a method for regenerating waste oil capable of miniaturizing fuel particles to improve fuel efficiency.
    [29] That is, according to the present invention, the waste oil is separated by methyl esterification by chemical treatment so as to be used in a diesel engine, and neutralized by adding a neutralizing agent to the collected upper organic layer, and then the neutralized salt is removed and recycled as a phosphate fertilizer and the impact energy of ultrasonic waves. By adding to increase the molecular motion to speed up the reaction and finally emulsifies.
    [30] In addition, the present invention is to increase the chemical and mechanical reaction rate of the waste oil by directly applying the ultrasonic treatment to the waste oil chemical treatment and waste oil to simplify the production process, reduce the cost and to reduce the environmental pollution by blocking the generation of waste water Its purpose is to provide a waste oil recycling apparatus.

    [31] Hereinafter, a method for regenerating waste oil of the present invention will be described.
    [32] First, in the refining step, the waste oil containing water, fatty acids, aldehydes, oxidation products and food debris is collected and the food debris is removed through a filter, and the waste oil from which the debris is removed is heated to a temperature of 50 to 80 ° C. After adding the adsorbent while maintaining it, the contact area is increased by increasing the molecular motion with ultrasonic wave and mixing device. In addition, in order to increase the degree of adsorption of impurities is stirred for 20 to 40 minutes while applying the impact energy of ultrasonic waves of 15 KHz ~ 100 KHz, the adsorbent in the stirring process is the water to hinder the methyl esterification reaction, the next step, Fatty acids, oxidation products, and neutralizers are adsorbed by physical binding force, and the adsorbent combined with the foreign matter is removed by a high performance centrifuge and a filter. The material used as the adsorbent is magnesium silicate, silica gel, silicic acid or alumina and the like, and the most efficient adsorbent is magnesium silicate. The process of refining the waste oil is the basic step to obtain a high quality renewable fuel.
    [33] Next, the reaction step of methyl esterification so as to be used as a fuel for diesel engines or boilers is carried out by adding a potassium hydroxide-methanol solution made by dissolving potassium hydroxide in methanol to the purified waste oil, and the reaction temperature is 50 to 80 ° C. By stirring while applying an ultrasonic impact energy for 30 to 65 minutes. In the process, fatty acids in the high viscosity triglyceride (triglyceride) that is the main component of the waste oil is broken and at the same time, the methyl group is chemically combined with the fatty acid to be converted into methyl ester. At this time, the molecular weight is reduced to 1/3, the viscosity is reduced to 1/10, the boiling point, the flash point is also reduced, the fatty acid methyl ester thus changed is similar to the diesel diesel fuel of the number of C molecules.
    [34] Subsequently, the step of separating the methyl esterified reaction solution is a step for passing the methyl esterified reaction solution through a high-performance centrifuge to obtain an oil layer which is a light methyl ester. It is the part containing 5% of metalol, and removes the heavy part glycerol and various compounds to obtain only the oil layer which is the methyl ester used as a fuel of a diesel engine or a boiler.
    [35] Since the methyl esterified oil layer contains a small amount of methanol and potassium hydroxide, in a conventional method, methanol is evaporated under reduced pressure, and a diluted acid solution is added to neutralize residual potassium hydroxide, and the acid solution used in the neutralization reaction is used. There is a problem in that a large amount of water supply and drying process for the separation of the moisture layer is necessary for the purpose of removing the existing water, neutralizing compounds, and various oxides, so that the economic cost and a large amount of waste water are generated, and a purification facility must be installed again. In addition, when the separated oil layer is used directly as a fuel, the engine is stopped by not only corroding parts by an organic solvent but also separation of water and methanol. Therefore, in the present invention, 5N% by weight of water, which is separated from methanol without evaporating methanol, is added by adding 3N phosphoric acid (H 3 PO 4 ) to 5% by weight of water, and then mixed with magnesium silicate, mixed with methyl ester oil, and neutralized. Salts, oxidation products and the like will be completely adsorbed and simply removed with a high performance (RPM 7500) centrifuge.
    [36] Finally, by applying the impact energy of the ultrasonic wave generated from the vibrator to the oil layer of the neutralized methyl ester and emulsifying the fuel by oil and fine emulsification through the cavitation, a small amount of water, ethanol and methyl ester as the neutralized oil layer Emulsification is carried out to obtain a fatty acid methyl ester which is an automobile fuel which is not phase separated.
    [37] On the other hand, perfect methyl esterification and shortening of reaction time can be aimed at the same time by stirring with an impeller simultaneously in the process of applying an ultrasonic impact energy to an oil layer and obtaining fatty acid methyl ester as mentioned above.

    [47] The heat generating tubes 9 and 91 installed in the stirring space 12 of the first treatment tank 1 and the reaction space 22 of the second treatment tank 2 are heated by heat medium oil supplied from the outside. Or heat transfer wires to transfer heat directly to heat and / or warm the stored contents to a predetermined temperature.
    [48] In another embodiment, as shown in FIG. 3A, the upper plate 31 of the vibrator 3 for generating ultrasonic waves of 15 KHz to 100 KHz forms the bottom plate constituting the stirring space 12 of the first treatment tank 1. The impact energy of the ultrasonic wave generated from the vibrator 31 is disposed so as to penetrate through the bottom surface of the bottom plate 24 constituting the reaction space 22 of the second treatment tank 2 or protrude therein. Impact energy of the ultrasonic wave generated from the vibrator 3 is directly applied to the solution by being directly transmitted to the solution, and the efficiency can be increased. The first and second treatments are made by inserting the lidena 33 in the least vibration part of the vibrator 3.

    [53] In addition, the first treatment tank (1) provides a refining and phase separation process by installing a circulation pump, a centrifugal separator, and a filter unit in the first treatment tank (1) to allow mass production through a continuous flow of processes. The two treatment tanks may be separated by neutralization and emulsification.
    [54] The following describes an embodiment of regenerating fuel through the waste oil regeneration method and the apparatus.
    [55] First, 100 Kg of waste oil from which waste is removed through the filter unit 7 is supplied to the stirring space 12 of the first treatment tank 1, and the stirring space 12 is used as heat generated in the heat generating tube 9. While heating and / or warming to a temperature of ˜80 ° C., 0.5 wt% of magnesium silicate as an adsorbent was added to the waste oil through the inlet 13, and the motor was applied for 20 to 40 minutes while applying impact energy of amplifying ultrasonic waves of 15 KHz to 100 KHz. By rotating the impeller (4) by the driving of (5), the circulating pump (10) is operated to remove the magnesium silicate, the adsorbent combined with the foreign matter, with a high performance (RPM 7500) centrifuge (16) and a filter. The filter is circulated through the upper filter unit 7 and purified.
    [56] Since the purified waste oil is a triglyceride, which is a high molecular material, a potassium hydroxide-methanol solution prepared by dissolving 1 kg of potassium hydroxide in 21.9 kg of purity 99% methanol through an inlet 13 is added to the purified waste oil in order to methyl ester it. While maintaining the temperature of 50-80 degreeC through the heat generating tube 9, while stirring for 30 to 65 minutes with the impeller 41, an ultrasonic shock energy is applied. In the process, the fatty acid is broken off from the triglyceride, and at the same time, the methyl group is chemically bonded to the fatty acid to be converted into methyl ester.
    [57] The reaction solution of the methyl esterified waste oil is separated by adjusting the RPM of the high-performance centrifuge 16. Since the separated glycerol can not be used as a fuel is discharged to the outside through the three-way valve 17 to recycle to make raw materials such as cosmetics. In the first treatment tank 1, about 90% of oil, which is methyl ester, remains.
    [58] Next, when 5% by weight of water is added to the methyl ester oil remaining in the first treatment tank 1 and the impeller 41 is turned, the oil is first stirred. Subsequently, 0.05 wt% (V / W) of 3N phosphoric acid (H 3 PO 4 ) and 0.5 wt% of magnesium silicate are mixed in the first stirred oil, and the impeller 41 is turned again for 20 minutes. do. Then, as the oil is neutralized by 3N phosphoric acid (H 3 PO 4 ) and magnesium silicate, impurities such as salts (K 3 PO 4 ) and oxidation products that can be recycled into phosphate fertilizers are produced.
    [59] In addition, by using the difference in specific gravity, the impurities are simply removed by the high performance (RPM 7500) centrifuge 16 of FIGS. 4 and 5A, 5B, and 5C. This process does not necessarily have to be performed in the first treatment tank 1, but when the circulation pump, the centrifuge and the filter unit are added to the second treatment tank, the operation may be performed by moving to the second treatment tank.
    [60] Since the neutralized methyl ester oil of the second treatment tank 2 contains a small amount of water and methanol, from the vibrator portion 31 of the vibrator 3 operated by the control of the ultrasonic oscillator 32 to emulsify them. Emulsified car with no phase separation by emulsifying fuel with atomization of oil and water through ultrasonic cavitation where bubbles are collected, grown, and collapsed by applying impact energy of generated 15 KHz ~ 100 KHz ultrasonic waves Fatty acid methyl ester is obtained as a fuel. The emulsified fatty acid methyl ester fuel is an emulsified state containing about 5% methanol and 2% water, and when the fuel is injected into a vehicle or a boiler combustion chamber, water accumulates in oil, causing a microexplosion caused by a temperature difference during combustion. To ensure that the fuel burns completely.
    [61] In addition, the neutralizing process or the emulsifying process using the motor 51 and the impeller 41 installed in the second processing tank 2 as shown in Figure 2, so that the stirring effect can be further increased to shorten the production time In addition, the required temperature is maintained through the heat generating tube 91 disposed in the second treatment tank 2.
    [62] In addition, in the above apparatus, the configuration separated into the first treatment tank 1 and the second treatment tank 2 is for mass production, and the filter portion 7 and the circulation pump installed in the first treatment tank 1 are used. (10) is installed in the second treatment tank (2) and the three-way valve (6) is removed to process the refining, phase separation, neutralization and emulsification as a single treatment tank to obtain fatty acid methyl ester which is a desired recycled fuel. .
    [63] While the invention has been shown and described with respect to specific embodiments thereof, it is well known in the art that various changes may be made therein without departing from the spirit or scope of the invention as set forth in the claims below. It should be noted that those who have can easily know.
    [64] The emulsified fatty acid methyl ester fuel obtained through the method and apparatus according to the present invention can be used as a safe and high quality fuel because no phase separation occurs, and when the emulsified oil is burned, a small amount of water contained in the oil explodes finely. Helps the complete combustion of the fuel and achieves the dual effect of preventing the pollution of the environment with little smoke, and consists of a simple process of purification, separation, neutralization and emulsification of waste oil through a simple manufacturing device and manufacturing process It can reduce the investment cost of facilities.
    [65] In addition, the present invention can prevent the generation of unnecessary impurities by recycling the debris generated in the process of neutralizing the waste oil, that is, salt (K 3 PO 4 ) as phosphate fertilizer.
