The present invention provides an oil vapor collecting device comprising: a first gathering tank for gathering oil vapor generated during refueling of a vehicle, through a suction pump; a cooling tower which has a plurality of feeding tubes formed therein to feed the oil vapor gathered in the first gathering tank to a lower portion thereof, and condenses a gas component included in the oil vapor fed to the feeding tubes; a second gathering tank which is located at the lower portion of the cooling tower and is connected to one side ends of the feeding tubes, the other side ends of which are connected to the first gathering tank, and in which a fluid component of the oil vapor collected via the cooling tower is gathered; a fluid storage tank which is located below the second gathering tank and stores the fluid component of the oil vapor gathered in the second gathering tank via the cooling tower; a refrigerant pipe which is located inside the cooling tower and condenses the fluid component included in the oil vapor fed via the feeding tubes; and a refrigerant supply means for supplying a refrigerant to the refrigerant pipe. Thus, the present invention can suction the oil vapor generated during refueling of a vehicle, thereby preventing dangerous situations such as an explosion and a fire, resulting from the oil vapor, and can reuse the fluid component of the collected oil vapor, thereby improving energy efficiency. |
