Abstract

The invention relates to an oil-gas separation device and a gas turbine engine. The oil-gas separation device comprises a cavity structure provided with a separation cavity. The wall face of the separation cavity is provided with an inlet, a first outlet and a second outlet. The inlet comprises multiple tangential channels. The multiple tangential channels enable oil-gas mixture to enter the separation cavity in the tangential direction. The first outlet is arranged in the radial direction of the separation cavity, the second outlet is arranged in the axial direction of the separation cavity, the separation cavity is rotated to achieve oil-gas separation for the oil-gas mixture, oil obtained after separation flows out through the first outlet, and gas obtained through separation flows out through the second outlet. In the embodiment of the oil-gas separation device and the gas turbine engine, the oil-gas mixture entering the separation cavity has the large tangential speed and small or almost zero radial speed and axial speed, standing time of vortical motion of the oil-gas mixture in the separation cavity can be longer, and the oil-gas separation efficiency can be better improved.

Description

technical field [0001] The invention relates to the technical field of oil-gas separation, in particular to an oil-gas separation device and a gas turbine engine. Background technique [0002] A gas turbine engine generally mainly includes a compressor, a combustor and a high-pressure turbine. The compressor is mainly used to compress air and make it enter the core engine; the combustor is mainly used to mix compressed air and fuel, and complete combustion to generate High-energy gas flow; while the high-pressure turbine is mainly used to extract energy from the high-energy gas flow ejected from the combustion chamber to drive the compressor. In an aviation turbofan engine, the low-pressure turbine located downstream of the core engine extracts energy from the high-energy gas flow ejected from the combustion chamber and drives the fan, which provides the main thrust generated by the engine. [0003] The rotor is usually fixed by multiple fulcrum bearings in the engine. Gen...
