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.
