Abstract: An apparatus is disclosed for the separation of solids from a mixture of solids and fluid, comprising a housing defining a plurality of separation chambers, each chamber being arranged around a central longitudinal axes and having a curved inner wall such that the intersection of the inner wall and a plane perpendicular to the central longitudinal axes is a concave line, whereby all central longitudinal axes are in one plane, and each chamber having an inlet opening, a solids outlet opening and at least one fluid outlet opening, whereby each fluid outlet opening is in communication with a fluid outlet conduit, and whereby the solids outlet opening of each chamber is in communication with a solids outlet conduit which is in tangential cooperation with the chamber, which apparatus further comprises one supply conduit for the mixture of fluid and solids whereby the supply conduit debouches into a supply opening that is formed by the combined inlet openings of all chambers which openings are communicating with ea

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).
