Abstract

A device (1) for separation of particles from a flow of gas is described. The device (1) comprises a first cyclone generator (6) comprising a first cyclone tube (8) with a length axis (4) and a first blocking means (9) arranged so that an annular first inlet (10) is arranged between the first cyclone tube (8) and the first blocking means (9). A first vortex generator (11) is arranged in the first inlet (10). The device comprises a further cyclone generator (12) comprising a further cyclone tube (13) with a length axis (4) and a further blocking means (14) arranged so that an annular further inlet (15) is arranged between the second cyclone tube (13) and the further blocking means (14), and a further vortex generator (16) arranged in the further inlet (15), and an outlet tube (22) comprising an outlet (23) and a length axis (4), which outlet tube (22) is arranged concentric in relation to the second cyclone tube (13). The first blocking means (9) overlaps the further inlet (15) seen in the direction of the length axis (4) and the second blocking means (14) has essentially the same extension as the outlet (23) seen in the direction of the length axis (4). The further cyclone generator (12) is arranged between the first cyclone generator (6) and the outlet (23).
