摘要： The present invention provides a centrifugal separator (1) for cleaning gas containing contaminants. The centrifugal separator comprising a stationary casing (2), enclosing a separation space (3) through which a gas flow is permitted, a gas inlet (20) arranged to permit supply of the gas to be cleaned into the stationary casing (2), a rotating member (7) comprising a plurality of separation members (9) arranged in the separation space (3) and being arranged to rotate around a first axis (X) of rotation, a gas outlet (28) arranged to permit discharge of cleaned gas out from the stationary casing (2), a drainage outlet (29) arranged in the stationary casing (2) and configured to permit discharge of liquid contaminants that have been separated from the gas out from the stationary casing, a drive unit (26) comprising a drive member (18) for rotating the rotating member (7). The centrifugal separator (1) further comprises a compression seal arranged for sealing stationary casing (2) against a further module (20, 26, 28) and comprising at least one elongated flap and at least one recess, the compression seal having a continuous extension around a second axis, wherein said at least one elongated flap is arranged in said at least one recess such that a compression force sealing is achieved by means of the flap surface being in contact with the recess surface.

摘要： Separation device (1) includes bottomed casing (2), rotating body (3), and blade (4). Casing (2) includes outer tubular portion (5) and inner tubular portion (6). Rotating body (3) is disposed inside inner tubular portion (6) and rotates about a rotation axis along an axial direction of inner tubular portion (6). Blade (4) is disposed between inner tubular portion (6) and rotating body (3), and rotates together with rotating body (3). Inner tubular portion (6) includes inner inflow port (61) and discharge port (63). Discharge port (63) discharges a solid contained in a fluid flowing into an inside of inner tubular portion (6) through inner inflow port (61) between inner tubular portion (6) and outer tubular portion (5). Outer tubular portion (5) includes a fluid outflow port and a solid discharge portion. The fluid outflow port causes the fluid flowing out from the inside of inner tubular portion (6) and flowing into the inside of outer tubular portion (5) to flow out to the outside of outer tubular portion (5). The solid discharge portion discharges the solid discharged from discharge port (63) of inner tubular portion (6) to the outside of outer tubular portion (5).
