| 摘要 |
The present invention pertains to an air separator with a stationary housing, which forms a helix when viewed in the axial direction, with a blade ring arranged stationarily in the housing with adjustable blades, and with a bladed separation wheel, which is arranged coaxially within the blade ring and rotatable around the axis of the housing. A raw material inlet opens tangentially into the annular space between the separation wheel and the blade ring, and the separation gas inlet, which is directed in parallel to the crude gas inlet, opens into the annular space between the blade ring and the helical housing. Finally, a raw material outlet is provided in the end zone of the flow in the annular space between the blade ring and the separation wheel. A coarse material outlet is arranged offset in relation to the separation gas outlet in the axial direction of the helical housing, as a result of which the helical housing has the three-dimensional shape of a worm with at least one revolution.
