The present invention efficiently collects the oil content of a gas using a rotary brush body. A collection unit 20, comprising a rotary brush body 21 and a back panel 22. The rotary brush body 21 has a large number of radially oriented linear materials 21b arranged in a tight, brush-form configuration, around a disc part 21a. The back panel 22 behind the rotary brush body 21 has window parts 22a at positions corresponding to the linear materials 21b. Partition frames 22b are provided to the window parts 22a. When the oil-containing gas is passed through the linear materials 21b and the window parts 22a of the back panel 22 from the front surface towards the back surface of the rotary brush body 21, the oil content collides with the linear materials 21b, adheres thereto, and becomes captured. Although the back panel 22 has the window parts 22a provided at positions corresponding to the linear materials 21b, the presence of the partition frames 22b prevents the linear materials 21b from collapsing rearwards beyond what is necessary, unraveling, and reducing the collection efficiency. |
