Abstract

A centrifugal air-oil separator for separating liquid particles from gases containing the liquid particles includes a substantially cylindrical air-oil separation chamber and a substantially conical liquid discharge chamber which are integrated with each other and are horizontally disposed, and an air-oil separation plate disposed between a gas supply port communicating with the air-oil separation chamber and a gas discharge port communicating with the liquid discharge chamber. A liquid discharge port is provided at a lowest portion between a largest-diameter portion of the liquid discharge chamber and the air-oil separation plate, and the liquid discharge port is covered thereabove with a reverse flow prevention wall. A strong swirl flow is generated in the air-oil separation chamber by the action of the air-oil separation plate to thereby enhance the liquid separation effect, and the reverse flow of liquid from the liquid discharge port to the liquid discharge chamber can be prevented.
