APPARATUS FOR RECOVERING VAPOR

PROBLEM TO BE SOLVED: To prevent a tank pressure from increasing, upon recycling a fuel component desorbed from an adsorption tank.SOLUTION: There is disclosed an apparatus 10 for recovering vapor, which includes a plurality of underground tanks 20A to 20C, an adsorption tank 30 filled with an adsorbent 32, a vapor recovery route 40, and a control device 50. The control device 50 includes a means 60 of identifying a tank unloading liquid fuel, a means 70 of switching the recovery route 40, and a means 80 of controlling the adsorption tank 30. A recycle pipe 200 connected to a discharge port of a vacuum pump 190 is connected to the gas phase of the underground tank 20B. One end of the recycle pipe 200 is connected to the discharge port of the vacuum pump 190 and the other end thereof communicates with a plurality of branch pipes 210A to 210C each inserted into the plurality of underground tanks 20A to 20C respectively. When a fuel component adsorbed by the adsorbent 32 is desorbed in the adsorption tank 30, the desorbed fuel component is recycled to each of the underground tanks 20A to 20C by the differential pressure relative to each of the underground tanks 20A to 20C via the recycle pipe 200 and the branch pipes 210A to 210C.
