As shown in the figure, an apparatus for producing an emulsified fuel according to an embodiment of the present invention includes a fuel tank 100 for storing and supplying fuel oil, an additive tank 200 for supplying additives, a water tank for storing and supplying water, A stirrer 400 that stirs the fuel oil filled in the fuel tank 100 and the water filled in the water tank 300, and a fuel tank 400 in which the fuel oil and water are stirred in the stirrer 400 And an emulsified fuel tank 500 for storing the emulsified fuel.

Hereinafter, each component constituting the apparatus for producing an emulsified fuel using heavy oil and waste oil according to the present invention will be described in more detail.

The fuel tank 100 has a predetermined capacity and can be filled with fuel oil.

The fuel oil supplied from the fuel tank 100 may be sent to the fuel oil improving tank 110 by pressure. At this time, the fuel oil in the fuel tank 100 can be pressure-fed to the fuel oil improving tank 110 with a constant pressure by the first pump P1.

The fuel oil improving tank 110 may include a fuel gauge 111, a fuel heater 112, and a fuel impeller 113.

The fuel gauge 111 checks the storage allowance amount of the fuel oil supplied to the fuel oil improving tank 110 in real time and controls opening and closing of the first solenoid valve EV1 provided separately according to the parameter for the storage capacity to be checked, So that the allowable storage capacity inside the oil improvement tank 110 can be maintained.

The fuel heater 112 heats the fuel oil stored in the fuel oil improving tank 110 to be maintained at a predetermined temperature. When the fuel oil is heated as described above, the viscosity is lowered and the fluidity is secured, so that the flow into the stirrer 400 becomes easy. The temperature heated and maintained by the fuel heater 112 may be set according to the chemical characteristics of the fuel oil or the working environment.

Further, since the fuel impeller 113, which is rotated around the rotating shaft, is provided in the fuel oil improving tank 110, the heat distribution of the fuel oil can be quickly made uniform or the viscosity of the fuel oil can be made uniform as a whole.

The fuel oil whose heating is completed in the fuel oil improving tank 110 is pumped to the agitator 400 via the first filter 120 by the second pump P2. A fuel supply line OL may be formed between the first filter 120 and the agitator 400 and a first atomization processing unit 130 may be formed in the fuel supply line OL.

As shown in FIG. 2, the first atomization processing unit 130 is formed to have a smaller diameter than the diameter of the fuel supply line OL, and the first mesh 140 is disposed therein.

The first mesh 140 is formed in a hollow cylindrical shape, and the body of the first mesh 140 is formed to have a mesh size of a predetermined standard. The first mesh 140 has a body having a mesh structure, and the outer circumferential surface of the first mesh 140 is spaced apart from the inner wall of the first atomization processing unit 130. As such a mesh structure, for example, a mesh structure having a dimension of 150 mm in the vertical and horizontal intervals can be applied.

Since the fuel oil passing through the inside of the first atomization processing unit 130 has a smaller diameter than the fuel supply line OL, the fuel is advanced at a higher flow rate, and the fuel passing through the through hole of the first mesh 140 And passes through a gap existing between the outer circumferential surface of the oil and the first mesh 140 and the inner wall of the first atomization processing section 130. When the opening formed at one end of the first mesh 140 is defined as an inlet port 141 and the opening formed at the other end is defined as an outlet port 142, the fuel oil introduced from the inlet port 141 flows into the outlet port 142, The mesh structure of the first mesh 140 is repeatedly formed in the through holes of the first mesh 140 and the outer circumferential surface of the first mesh 140 and the gap between the first mesh 140 and the first mesh 140 in the zigzag direction, A vortex is generated that passes through. Through this process, the atomization of the fuel oil can be repeatedly performed.

In addition, a separate first flow meter Q1 is disposed between the second pump P2 and the first filter 120 to measure the flow rate in real time.

The first filter 120 filters the foreign matter present in the fuel oil supplied from the fuel oil improving tank 110. The fuel oil filtered by the first filter 120 is supplied to the stirrer 400.

The additive tank 200 is provided with a space for storing the additive therein. The additive acts to stir water and fuel oil.

In addition, the additive heater 201 and the additive impeller 202 may be contained in the additive tank 200.

The additive heater 201 heats the fuel oil stored in the additive tank 200 to be maintained at a predetermined temperature. When the additive is heated as described above, the viscosity of the additive is lowered and fluidity is secured, so that the flow of the additive into the stirrer 400 becomes easy. The temperature heated and maintained by the additive heater 201 may be set depending on the chemical characteristics of the additive or the working environment.

In addition, the additive impeller 202, which rotates about the rotation axis in the additive tank 200, can be provided to rapidly make the heat distribution of the additive uniform and to make the viscosity of the additive uniform as a whole.

The additive heated in the additive tank 200 is fed by the third pump P3 to the agitator 400 via the additive feed line AL and the first strainer 120. [ At this time, a separate second flow meter Q2 is disposed between the third pump P3 and the first filter 120 to measure the flow rate in real time. At this time, the second solenoid valve EV2 may be installed on the additive supply line AL so that the additive supply amount can be adjusted according to the flow rate of the second flow meter Q2.

The water tank 300 has a predetermined capacity, and water can be stored therein. The water stored in the water tank 300 can be sent to the water improving tank 340 by the fourth pump P4. Here, a second filter 310 may be installed between the water tank 300 and the water improving tank 340. The second filter 310 filters the foreign substances present in the water that is transported from the water tank 300 to the water improving tank 340.

The water filtered through the second filter (310) is supplied to the water improving tank (340).

A water gauge 341 and a water heater 342 may be included in the interior of the water improving tank 340.

The water gauge 341 can check the amount of water supplied in the water improving tank 340 in real time. The third solenoid valve EV3 may be disposed between the fourth pump P4 and the second filter 310 and may be connected to the third solenoid valve EV3 depending on the amount of water checked by the water gauge 341. [ The amount of water to be supplied into the water improving tank 340 can be controlled.

The water heater 342 heats the water inside the water improving tank 340 to maintain a temperature of about 85 ° C. When the water is heated to a temperature of 85 캜, fluidity can be secured as described above.

The heated water in the water improving tank 340 is pumped to the agitator 400 via the water supply line WL by the fifth pump P5. Here, the second flow meter Q2 is disposed between the fifth pump P5 and the stirrer 400 to measure the flow rate in real time.

The second atomization processing unit 320 may be formed during the water supply line WL.

3, the second atomization processing unit 320 is formed to have a smaller diameter than the diameter of the water supply line WL, and the second mesh 330 is disposed inside the second atomization processing unit 320 .

The second mesh 330 is formed in a hollow cylindrical shape, and the body of the second mesh 330 is formed to have a predetermined mesh size. The second mesh 330 has a body having a mesh structure, and the outer circumferential surface of the second mesh 330 is spaced apart from the inner wall of the second atomization processing unit 320. For example, a mesh structure having a dimension of 10 mm or less may be applied to such a mesh structure. In particular, the longitudinal spacing of the second meshes 330 may be set smaller than the longitudinal spacing of the first meshes 140. The horizontal and vertical intervals of the mesh are caused by the viscosity difference between fuel oil and water, and can be variously set depending on the viscosity characteristics of fuel oil and water.

The water passing through the inside of the second atomization processing unit 320 has a diameter smaller than that of the water supply line WL so that the water flows through the through hole of the second mesh 330, And passes through a gap existing between the outer circumferential surface of the second mesh 330 and the inner side wall of the second small diameter portion 320. At this time, if the opening formed at one end of the second mesh 330 is an inlet 331 and the opening formed at the other end is defined as an outlet 332, the water introduced from the inlet 331 flows through the outlet 332 The mesh structure of the second mesh 330 is repeatedly formed in the through hole of the second mesh 330 and the outer circumferential surface of the second mesh 330 and the gap between the second small diameter portions 320 in a staggered manner, A passing vortex is generated. Through this process, the atomization of water can be repeatedly carried out.

On the other hand, a temperature gauge (not shown) may be provided in the fuel oil improving tank 110 and the water improving tank 340, respectively. When the temperature is lower than the set temperature, the respective heaters are operated, If the temperature is higher than the predetermined temperature, the heater can be controlled to be shut off. Such a set temperature can be set to, for example, 85 캜, but it is not limited to this because it can be adjusted according to the chemical characteristics of fuel and water.

The stirrer 400 stores the fuel oil, the additive, and the water, which are fed from the fuel oil improving tank 110, the additive tank 200, and the water improving tank 340, as described above.

The stirrer 400 may include a stirrer homomix 401 and a stirrer heater 402.

The stirring homomix 401 is rotated about the rotating shaft and performs a function of uniformly mixing the mixture supplied into the stirrer 400 using the rotating force of the rotating vane formed at the end of the rotating shaft to promote emulsification of the mixed oil .

At this time, the stirring homomix (401) is pressurized to the first emulsified fuel tank (500) by stirring the fuel oil, the additive and the water for about 10 minutes to 30 minutes.

That is, the mixed oil produced in the agitator 400 is pressure-fed by the sixth pump P6 to the first emulsified fuel tank 500 along the discharge line EL at a constant pressure. At this time, the purifier 410 may be disposed between the sixth pump P6 and the first emulsified fuel tank 500. The purifier 410 may function to filter foreign matter present in the mixed oil.

Thereafter, the emulsified fuel stored in the first emulsified fuel tank 500 may be sent to the cooling device 510. The cooling device 510 functions to cool the emulsified fuel that has been heated to a higher temperature than necessary.

The temperature is lowered to a temperature required by the cooling device 510 and then stored in the second emulsion fuel tank 520 to complete the emulsion fuel production.
