ABSTRACT:
The apparatus for removing dust particles from an air stream, particularly for ventilating mines, comprises a centrifugal separator (3), which rotates in a housing (1), a blower (4), and a device (6, 7) for spraying or atomizing water and for delivering it to the air stream entering the centrifugal separator (3). The centrifugal separator (3) comprises a plurality of blade wheel sections (8, 9) having blades (14) which are joined to walls (10) which flare like funnels. The blades of said blade wheel sections (8, 9) extend approximately in axial planes. Said blade wheel sections (8, 9) are preceded at the air inlet end by at least one blade/wheel section (15) in which the generatrices of the blade surfaces (blades 17) which are equidistant from the axis are inclined by an angle of incidence (.alpha.) from lines which extend parallel to an axial plane (21), in a sense which is opposite to the sense in which the resultant vector (R) of the axial air entry velocity (v) and the peripheral velocity (u) of the blades (17) is inclined from the axial plane (21) (FIG. 2).
