Large oil particles are initially separated on the inner wall of the cyclone oil separator 8 under the action of centrifugal force. The separation is completed under the action of gravity. The gas then passes through the secondary filter element 6 to separate the oil stains again. The secondary filter element 6 is filled with an oil removal medium containing built-in activated carbon 5 to further remove the oil from the gas. The gas then passes through the intermediate flange 3 and the activated carbon baffle 4 and re-enters the secondary filter element 6 for oil removal again.
