Description

Liquid fuel's reforming system by ultrasonic wave

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic reforming system for a liquid fuel in which ultrasonic waves are applied to a highly viscous, low quality liquid fuel to be reformed into a high quality emulsion oil.

High-viscosity, low-quality liquid fuels generate large amounts of harmful gases during combustion. This is because it is difficult to atomize the fuel, thereby increasing the firing point of the fuel. Fuels with high flash points reduce combustion efficiency, leading to incomplete combustion of the fuel. In particular, low-quality liquid fuels contain large amounts of non-combustible impurity materials, further reducing the combustion efficiency of the fuel.

On the other hand, if the combustion efficiency is low, a relatively large amount of fuel is consumed rather than a low viscosity and high quality liquid fuel. In addition, harmful gases generated during the combustion of highly viscous and low-quality liquid fuels enter the human body through the respiratory tract and act as carcinogenic components or accumulate in the lungs, causing chronic lung disease. In particular, carbon monoxide (CO) and hydrocarbons (HC) contained in the combustion gas interfere with the oxygen supply of the human body, and have a fatal effect on the human body, such as irritating the mucous membrane or eyes.

Therefore, there is an urgent need to develop a liquid fuel reformer that reforms a highly viscous and low quality liquid fuel into a high quality emulsified oil to improve combustion efficiency and to reduce harmful gas and fuel consumption.

In response to this demand, the present inventors use ultrasonic wave atomizer of liquid fuel of Patent No. 110354 filed and registered by the present inventors to apply ultrasonic wave to high viscosity and low quality liquid fuel to reformate it into high quality emulsion oil. An ultrasonic reforming system of liquid fuel has been developed.

Accordingly, an object of the present invention is to provide an ultrasonic reforming system of liquid fuel which can reduce fuel consumption rate and harmful gas by reforming a liquid oil having high viscosity and low quality with good quality emulsified oil using ultrasonic waves.

The reason for heating the liquid fuel is to activate the liquid fuel.

In addition, the water tank 20 supplies water in order to reform the viscous and low-quality liquid fuel into a high quality emulsified oil. As shown in FIG. 3, the water inlet 21 for supplying water and the water from which the water is discharged are provided. It has an outlet 22. The water inlet 21 is provided with a cap 23 for opening or closing the water inlet 21, and the cap 23 is provided with a pressure control valve 24 for releasing the negative pressure in the water tank 20. In addition, a drain valve 25 may be installed at the bottom of the water tank 20 to discharge foreign matters collected on the bottom surface of the water tank 20, and the remaining oil in the water tank 20 may be disposed at the side wall of the water tank 20. The flowmeter 26 which shows a fuel amount is provided.

Meanwhile, a heat wire 27 for heating water is disposed around the outer surface of the water tank 20, and a heat insulating material 28 is disposed around the heat wire 27 to insulate the water tank 20 from the outside. The hot wire 27 is operated by the temperature controller 27a installed on one side, and the temperature controller 27a controls the water stored in the water tank 20 to be always maintained at about 100 ° C. The reason why the water is heated is to make the water into saturated water so that it is easier to mix with a low viscosity liquid fuel having high viscosity. In addition, the water tank 20 is provided with a flow control device (29a) and a pressure control device (29b) for adjusting the flow rate and pressure of the water so that the heated water can be mixed and maintained with the liquid fuel and 10-20% by volume do.

In addition, the stirring apparatus 30 has a stirrer 37. The stirrer 37 is comprised in the stirring chamber 31, and consists of the stirring blade 37a which stirs a liquid fuel and water, and the stirring motor 37b which rotates the stirring blade 37a. Like the fuel tank 10 and the water tank 20, the stirring device is arranged with a heat insulating material 39 so as to insulate the stirring chamber 31 and the outside around the outer surface.

On the other hand, the ultrasonic reformer 40 applies ultrasonic waves to the liquid fuel and water stirred to some extent by the agitator 30 to reform the high viscosity and low quality fuel into a high quality emulsified oil. In other words, in order to reform a highly viscous and low quality fuel into a good emulsified oil, water is mixed with a highly viscous and low quality liquid fuel, and then a surfactant such as soap is added to reduce the interfacial tension between the liquid fuel and the water. The so-called emulsification process is carried out in which water in oil, which is a dispersed phase in a liquid fuel, is dispersed in a particulate state. However, in the present invention, by applying ultrasonic waves to liquid fuel and water by using the ultrasonic vibrator and ultrasonic vibration generator of Patent No. 110354 developed and registered by the present inventors in place of a surfactant such as soap, the fine particles of the dispersed phase are micronized. In order to disperse water in the liquid fuel as a dispersion medium in a particulate form (Water in oil).

Ultrasonic reformer 40 having this principle has a case 41 consisting of an upper case 50, a lower case 60 and a heating plate 70, as shown in Figs. A cooling chamber 52 is formed in the upper case 50, and a cooling fan 53 is installed at one side of the cooling chamber 52 to distribute external air to cool the cooling chamber 52. In addition, a plurality of through holes 55 are formed on an upper surface of the upper case 50, and an ultrasonic vibration generator 56 is installed on the side of the upper case 50.

A plurality of cylinders 62 are formed in the lower case 60, and the ultrasonic generator 65 is disposed in each cylinder 62. The cylinders 62 are in communication with each other by the passage 63 such that the mixture of fuel and water introduced through the inlet 62a passes through each cylinder 62 in turn and finally discharges through the outlet 62b. This is for the fuel passing through the cylinder 62 to receive more ultrasonic energy. A return hole 63 is formed at one side of the cylinder 62 to return the boil-off gas generated in the fuel reforming process to the fuel tank 10. The return hole 64 is connected to the return pipe 16 of the fuel tank 10 by a connecting pipe.

The reflector plate 68 causes the liquid fuel and water vibrated by the vibrator 66 and the horn 67 to collide with the pressure wave while colliding with the reflector plate 68. Here, the process and the principle of the liquid fuel and the water micronized by the vibrator 66, the horn 67 and the reflector plate 68 are described in detail in Patent No. 110354, the description thereof will be omitted.

The liquid fuel introduced into the cylinder 62 through the inlet 62a by this configuration passes through the cylinder 62 in sequence, so-called emulsified oil in which water is dispersed in the liquid fuel finely by ultrasonic waves. Water in oil). In particular, the water droplets contained in the emulsified oil are further atomized while repeatedly passing through the cylinder 62 several times to reform the liquid fuel into a higher quality emulsified oil. Good emulsified oils promote microexplosion to improve fuel combustion efficiency. On the other hand, the soft part of the fuel is converted into a gas upon receiving the ultrasonic energy, and this gas is returned to the fuel tank 10 through the return hole 63 together with the volatile matter. Here, the ultrasonic reformer 40 is provided with a return pump (not shown) for sucking the gas inside the cylinder 62 and transporting it to the fuel tank 10.

On the other hand, the pump 80 is to apply a predetermined pressure to the liquid fuel discharged from the ultrasonic reforming device 40, the nozzle 90 burner of the good quality emulsified oil discharged from the pump 80 at a predetermined pressure ( Injection into the combustion chamber of B).

Looking at the operation of the present invention having such a configuration as follows. First, when the liquid fuel and water heated properly in the fuel tank 10 and the water tank 20 flow into the stirring device 30, the stirring device 30 stirs the liquid fuel and water as appropriate. Then, the liquid fuel and water stirred in the agitator 30 flow into the ultrasonic reformer 40, and the liquid fuel and water introduced into the ultrasonic reformer 40 open the cylinder 62 of the case 41. It passes through one after another and is reformed into high quality emulsified oil. And the liquid fuel reformed into a good quality emulsified oil is discharged to the outside through the nozzle 90 while having a predetermined pressure by the pump (80).

Meanwhile, in the present invention, the water is mixed with the liquid fuel to be reformed into a high quality emulsified oil, but the liquid fuel is high in viscosity and low in quality by directly injecting the liquid fuel into the ultrasonic reformer without mixing the water into the liquid fuel. Can also be modified.

In the present invention, by using ultrasonic waves, the liquid fuel having high viscosity and low quality is a high-quality emulsified oil having low viscosity and high quality, thereby improving the combustion efficiency of the liquid fuel and of course harmful gases generated during the combustion of the liquid fuel. In particular, it has the advantage of reducing the generation of carbon monoxide (CO) and hydrocarbons (HC) that have a fatal effect on the human body to the maximum.

In addition, by using the ultrasonic reforming system of the present invention by modifying the vegetable oil having a high viscosity and flash point to the emulsion oil having a low viscosity and flash point, it can also be used as an alternative energy to replace petroleum.

For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.
