Fuel-oil refining device

Abstract

The present invention is characterized by comprising: a main unit which incorporates a fuel-inflow port for fuel oil supply, a fuel-discharge port for discharging fuel oil that has finished being refined and a drainage discharge pipe for collecting and discharging untreated fuel oil, and a sludge box for storing sludge that has been separated out from the fuel oil; an ultrasound tank which receives fuel oil supplied from the fuel-inflow port, and adjusts the particle size of the fuel oil and the viscosity and surface tension of the fuel oil by means of ultrasound; a vacuum chamber which receives fuel oil supplied from the ultrasound tank, and of which the inside is maintained in a vacuum state such that the specific volume and the surface area of the fuel oil are maximized via a baffle panel; a water-fraction elimination tank of which one side is connected to the vacuum chamber and the other side is connected to a vacuum pump, and which eliminates the water fraction from the fuel oil by using air heated to a high temperature and the reduced pressure of the vacuum state created due to the vacuum chamber; an oil-refining filter which receives fuel oil supplied from the vacuum chamber and filters the received supply of fuel oil by means of centrifugation so as to trap sludge contained in the fuel oil; an ion chamber which eliminates and bums particles including fine foreign matter remaining in the fuel oil in the state after the sludge has been eliminated; and a control panel which is constituted on one surface of the main unit, sets the operating conditions of the ultrasound tank, vacuum chamber and water-fraction elimination tank, and controls whether to provide power for refining the fuel oil.

1 . A fuel-oil refining device comprising:
 a main body portion including a fuel inlet port for supplying a fuel oil, a fuel discharge port for discharging the refinement-completed fuel oil, a drain pipe for collecting and discharging the untreated fuel oil, and a sludge box for storing therein sludge that is separated from the fuel oil;   an ultrasound tank configured to receive the fuel oil that is supplied from the fuel inlet port and to adjust a particle size, viscosity, and surface tension of the fuel oil by means of ultrasound;   a vacuum chamber configured to receive the fuel oil that is supplied from the ultrasound tank and to maintain an inside thereof in a vacuum state so that a specific volume and a surface area of the fuel oil are maximized through a baffle panel;   a moisture removal tank having one side that is connected to the vacuum chamber and the other side that is connected to a vacuum pump and configured to remove the moisture from the fuel oil using air which is pressure-reduced to the vacuum state by the vacuum chamber and is heated to a high temperature;   an oil refining filter configured to receive the fuel oil that is supplied from the vacuum chamber and to collect the sludge that is included in the fuel oil through filtering of the received fuel oil through centrifugation;   an ion chamber configured to remove and burn particles including fine foreign substances that remain in the sludge-removed fuel oil; and   a control panel provided on one surface of the main body portion to set driving conditions of the ultrasound tank, the vacuum chamber, and the moisture removal tank and to control whether to provide a power for refining the fuel oil.   
     
     
         2 . The fuel oil refining device of  claim 1 , wherein the main body portion further comprises:
 an exhaust pipe configured to exhaust harmful gases that are generated during the refining of the fuel oil; and   an air vent configured to discharge high heat that is generated during driving of the fuel-oil refining device.   
     
     
         3 . The fuel oil refining device of  claim 1 , wherein the ultrasound tank comprises:
 an oil storage tank configured to store therein the fuel oil that is transported from the oil tank; and   a particle adjustment tank configured to pulverize particles of the fuel oil through emission of the ultrasound onto the fuel oil that is stored in the oil storage tank so that the fuel oil is composed of the particles having a predetermined size.   
     
     
         4 . The fuel oil refining device of  claim 1 , wherein the oil refining filter comprises:
 a plurality of mesh filter members composed of predetermined mesh nets to perform filtering in stages;   a sludge removal means configured to remove the sludge that sticks to outer surfaces of the mesh filter members; and   a discharge screw member configured to collect and discharge the removed sludge.   
     
     
         5 . The fuel oil refining device of  claim 1 , further comprising an oil cooling system configured to cool the refinement-completed fuel oil. 
     
     
         6 . The fuel oil refining device of  claim 1 , wherein the drain pipe withdraws the untreated fuel oil into an oil recycle tank or re-transports the untreated fuel toward the ultrasound tank by means of a recycle pump. 
     
     
         7 . A method of refining fuel oil comprising supplying fuel oil to the device of  claim 1 .
