To provide flammable refrigerant recovery equipment that can exhaust a treated refrigerating machine oil without stopping a recovery operation of the refrigerating machine oil.

The flammable refrigerant recovery equipment 1 includes a recovery tank 2, a treatment tank 3 provided independently of the recovery tank 2, a transfer pipe 18, a transfer valve 19, and a pipe 27 for exhaust. The transfer pipe 18 connects the recovery tank 2 and the treatment tank 3. Moreover, a solution S collected in the recovery tank 2 runs in the transfer pipe 18 for transfer from the recovery tank 2 to the treatment tank 3. Moreover, a process for exhausting the treated refrigerating machine oil from the treatment tank 3 is carried out by making the recovery tank 2 and the treatment tank 3 independent by closing the transfer valve 19 to intercept the flow of the solution S passing the transfer pipe 18. As a result, the treated refrigerating machine oil can be exhausted without stopping the recovery operation, and working efficiency can be improved significantly.
