AI Technical Summary
⚠Technical Problem
In existing centrifugal separators, oil contaminants can easily escape through the separator, increasing the risk of oil carryover in clean gas and affecting the efficiency of the turbocharging system.
⚗Method used
Design a centrifugal separator including a stationary shell, a rotating component and a stationary axial surface. The rotating component has a rotatable axial surface and an edge portion. The edge portion extends radially inward from the rotatable axial surface to form an annular sealing gap to prevent oil contaminants from escaping through the sealing gap.
🎯Benefits of technology
It effectively reduces the risk of oil contaminants escaping from clean gas, improves the efficiency of the turbocharging system, and ensures the cleanliness of the gas.

Abstract
The present invention provides a centrifugal separator (1) for cleaning a gas containing contaminants. The separator includes: a stationary shell (2) that surrounds a separation space (3) through which airflow is permitted; a gas inlet (20) that extends through the stationary shell (2) and allows the supply of gas to be cleaned; a rotating component (7) that includes a plurality of separation components (9) arranged in the separation space (3) and arranged to rotate about a rotation axis (X); a gas outlet (28) configured to allow the discharge of clean gas and including an outlet opening through the wall of the stationary shell (2); a discharge outlet (29) arranged in the lower portion (26) of the stationary shell (2) and configured to allow the discharge of liquid contaminants separated from the gas to be cleaned; and a drive component (22) for rotating the rotating component (7). The centrifuge also includes a stationary axial surface (40) extending into the separation space (3), and the rotating component (7) includes a rotatable axial surface (41) arranged radially outward of the stationary axial surface (40); wherein the rotatable axial surface (41) is arranged at the gas inlet (20) such that liquid contaminants present in the gas to be cleaned are pressed against the rotatable axial surface during operation (40), and further wherein the rotating component (7) includes an edge portion (44) extending radially inward from the rotatable axial surface (41) and forming an annular sealing gap (42) between the rotating component (7) and the stationary axial surface (40).
