A vapor recovery device according to the present invention comprises a buffering unit (40) which receives and buffers discharged vapor having uplift pressure through a first inlet hole (402) connected to a vapor discharge pipe (400) for the discharge of the vapor and has an inserting hole (404) on the bottom surface to insert the buffered vapor into a cooling tank (42); the cooling tank (42) which has a cooling line, in which refrigerants flow, on the inner surface, stores antifreeze therein, cools the vapor received through the inserting hole (404), and discharges the vapor through a discharge hole (422) formed on the bottom plane; and a vapor recovery storage unit (44). The bottom surface of the buffering unit (40) and the top surface of the cooling tank (42) have the same area. Multiple vapor passing pipes (420), which have a pipe shape which is twisted into a coil shape, are installed by passing through the antifreeze inside the cooling tank (42). A vapor condensation recovery device according to the present invention pushes air including vapor in the vapor condensation recovery device using pressure of a storage tank regardless of stage I or stage II. A cooling pipe is directly installed on the inner surface of a buffering tank and multiple coil-shaped cooling recovery pipes, connected in parallel, pass through the cooling tank in which cooling speed is improved. Therefore, the vapor condensation recovery device removes a blockage phenomenon and increases condensation liquefied mass flow rate by 40% than the conventional technology. |
