The method of claim 1, The vacuum suction unit, Vacuum pump; A vacuum connection line connecting the vacuum pump and the vacuum chamber; And And a vacuum trap provided on the vacuum connection line to separate oil from the gas sucked into the vacuum from the vacuum chamber. The vacuum trap is an oil refining device, characterized in that the level sensor for sensing the water level of the oil separated from the gas. The method of claim 1, A discharge filter provided to the discharge line to filter oil discharged through the discharge line, and And a minimum pressure valve provided at an outlet end of the discharge filter to maintain the pressure at the outlet end of the discharge filter at a constant pressure. The method of claim 1, Oil refining apparatus further comprises a porous plate provided in the first space. delete A vacuum chamber configured to partition an inner space into a first space portion and a second space portion perpendicularly to the inside thereof, and a vacuum chamber having a flow path hole formed at a lower end of the partition wall so that the spaces communicate with each other; A flow passage plate provided in the second space portion, the flow passage plate including a vertical wall disposed adjacent to the partition wall and having an upper end at a position higher than the flow path hole; A vacuum suction unit connected to the vacuum chamber and vacuum suctioning gas in the vacuum chamber internal space; A suction line through which oil for supplying to the vacuum chamber is sucked; An injection nozzle part including a plurality of injection nozzles and injecting oil supplied through the suction line to the first space part; A discharge line connected to the second space part and configured to discharge oil; A bypass line connecting the discharge line and the vacuum chamber so that oil discharged through the discharge line is bypassed to the vacuum chamber; A variable flow rate discharge valve configured to variably control a flow rate of oil bypassed through the bypass line; A sensor for sensing a level of oil collected in the second space part; And And a heater connected to the suction line to heat the oil supplied through the suction line, and at least a part of the heater passes through the interior of the vacuum chamber to heat the oil inside the vacuum chamber. The oil sprayed from the first space portion is separated into a foam layer and an oil layer disposed below the foam layer, and the oil forming the oil layer in a state separated from the foam layer is formed through the flow path. Flows into the second space part, The oil refining device, characterized in that at least one of the respective injection nozzles is blocked when the level of the oil collected in the second space portion through the detection sensor is more than a predetermined level. The method of claim 14, A suction amount control valve is provided between each injection nozzle, When the water level level of the oil collected through the detection sensor is detected to be above a certain level, the suction amount control valve is turned off (OFF) and at least one of the respective injection nozzles are shut off Device. The method of claim 14, The vacuum suction unit, Vacuum pump; A vacuum connection line connecting the vacuum pump and the vacuum chamber; And And a vacuum trap provided on the vacuum connection line to separate oil from the gas sucked into the vacuum from the vacuum chamber. The vacuum trap is an oil refining device, characterized in that the level sensor for sensing the water level of the oil separated from the gas. The method of claim 14, A discharge filter provided to the discharge line to filter oil discharged through the discharge line, and And a minimum pressure valve provided at an outlet end of the discharge filter to maintain the pressure at the outlet end of the discharge filter at a constant pressure.
