OIL-GAS SEPARATOR, OIL-GAS SEPARATION SYSTEM AND AIRCRAFT ENGINE

WIPO Patent Application WO/2018/113332

A1

Provided is an oil-gas separator, comprising a separation cavity and a rotary member for oil-gas separation, wherein the rotary member is arranged inside the separation cavity so that the separation cavity is divided into at least two levels of cavity via the rotary member; the at least two levels of cavity are in sequential fluid communication; and the cavity located the furthest upstream among the at least two levels of cavity is in fluid communication with a first cavity (a) having an oil-gas mixture, such that the oil-gas mixture, after flowing out of the first cavity (a), enters the at least two levels of cavity by means of the cavity located the furthest upstream such that perform oil-gas separation is carried out at least twice. The device enables the separation cavity to be divided into at least two levels of cavity by means of arranging the rotary member, such that the oil-gas mixture, after primary oil-gas separation is completed in one level of cavity, can enter another level of cavity for secondary oil-gas separation, thereby realizing performing oil-gas separation at least twice, and having a higher separation efficiency. Further provided are an oil-gas separation system and an aircraft engine.
