ABSTRACT:
Apparatus for separating solid particles from a fluid, comprising a swirl chamber (3) provided with a curved wall, a tangential inlet (9) and a solids outlet (13), both arranged perpendicular to the central longitudinal axis (5) of the swirl chamber (3). A swirl tube (16) extends coaxially into the swirl chamber (3) and has an open end (20) arranged in the swirl chamber (3) and a solids outlet opening (22) arranged outside the swirl chamber (3). A fluid outlet tube (28) has an outlet part (34) extending coaxially into the swirl chamber (3) in a direction opposite to the direction in which the swirl tube (16) extends and an inlet part (32) arranged in the swirl tube (16). Swirl imparting means (46) are arranged between the swirl tube (16) and the fluid outlet tube (28), so as to impart a swirl in the swirl tube (16), which swirl has the same direction of rotation as in the swirl chamber (3).
