In order to protect the engine blades and improve the engine power, the reduction of the moisture content in the air entering the air inlet channel is a main problem which needs to be solved urgently at present.

In actual operation, the movement of the large-scale solid particles is mainly determined by the initial velocity and inertia of the large-scale solid particles.
However, in the gas water or gas-steam mixture, the diameter distribution range of water drops is 2 μm-30 μm, and the inertia of the water drops is small, so that the separation of water drop particles in the air is difficult to realize by using the inertia particle separator. Meanwhile, the device also has the defects of large occupied space, large flow loss in the separation process and the like. In order to improve the separation efficiency and reduce the space of the air inlet, a new air-water or air-steam separation mode is urgently needed.
