Marine high-pressure air relief system

The utility model relates to the technical field of ship manufacturing, and discloses a marine high-pressure air relief system which comprises a pressure relief pipe, an air outlet pipe and a processing cabinet, the pipe wall of the pressure relief pipe is connected with a plurality of relief pipes with the pipe diameter far smaller than that of the relief pipe, and the air outlet pipe is communicated with the pressure relief pipe and used for discharging high-pressure air in the pressure relief pipe. And the treatment cabinet is communicated with the pressure relief pipe and is used for treating oil-containing drainage water flowing to the treatment cabinet from the pressure relief pipe. Compared with the prior art, the large-drift-diameter pressure relief pipe is arranged to achieve buffering of high-pressure drained water, the pressure of the drained water is effectively reduced, high-pressure gas mixed in the drained water is discharged, water mist and accumulated water are avoided, meanwhile, the oil-con
