Abstract
Disclosed is an oil separation barrel, which includes a barrel body and an oil separation and filtration structure provided in the barrel body, the barrel body provided with an oil separation cavity and an output port. An output gas flow is filtered by the oil separation and filtration structure, then enters the oil separation cavity, and finally is output from the output port. At least part of a barrel wall of the barrel body forming the oil separation cavity includes two or more layers of circumferential walls. The output gas flow flows in the oil separation cavity in such a manner that it changes the advance direction multiple times, which can make the flow field uniform and reduce noise and vibration; and the output gas flow impacts the circumferential wall surfaces in the oil separation barrel multiple times, which can further improve the efficiency of oil separation.
