A compressor exhaust device comprises an exhaust pipe and a separating portion. The separating portion includes an inlet end and an outlet end. The exhaust pipe is inserted in the shell of the compressor. The separating portion is arranged in a circular arc shape inside the shell of the compressor. The inlet end of the separating portion is connected to the internal cavity of the compressor. The outlet end of the separating portion is connected to the exhaust pipe. Since the novel exhaust device is set, the oil-gas separation is carried out by the action of centrifugal force. The oil-gas separation is effectively reduced, the storage capacity and reliability of the compressor is increased, and the exhaust process is optimized. The flow resistance loss of the exhaust is reduced.
