Cyclone separator

A cyclone separator for separating at least two phases of a fluid, the cyclone separator comprising:

• a base housing through which the fluid can flow in a helical pattern and having a conical separation chamber with an upper end and a lower end, wherein the upper end and lower end each respectively have a wall, and a central axis that extends through the base housing and between the two ends of the conical separation chamber;
• a central separation tube arranged inside the conical separation chamber, extending between the two ends of the conical separation chamber, continuous in its length, and concentric to the central axis, with a cylindrical wall having a surface facing an inner cross-section with a first surface profile and a surface facing away from the inner cross-section with a second surface profile;
• wherein the base housing has, at the upper end, a head section with an inner radius and with at least one tangentially attached inlet opening for the fluid, as well as at least one light fraction outlet opening with a cross-section, and at the lower end, at least one expansion chamber and at least one heavy fraction outlet opening, wherein the separation chamber tapers conically, at least in sections, along the central axis in the direction of the lower end, with a constant cone angle α relative to the central axis;
• wherein at the transition between the separation chamber and the expansion chamber, a stabilizer is provided for the purposes of stabilizing the central separation tube and controlling the flow of the light fraction, and wherein the stabilizer has a first annular stabilizer wall and a second annular stabilizer wall that is concentric with the first annular stabilizer wall, each annular stabilizer wall having a surface facing toward the inner cross-section and a surface facing away from the inner cross-section, wherein both annular stabilizer walls are arranged in a plane and wherein the first and/or the second annular stabilizer wall has fins with a fin angle δ, wherein the stabilizer is detachably connected to the base housing on the inner side of the base housing of the lower end, and the first annular stabilizer wall is locked at least with a section of a central pin on a base of the expansion chamber, the central pin being arranged concentrically relative to the central axis in order to receive the central separation tube;
• wherein the first annular stabilizer wall has the fins on the surface facing away from the inner cross-section and the second annular stabilizer wall has the fins on the surface facing toward the inner cross-section;
• and
• wherein a flow guide element extending concentrically around the central separation tube is provided on the inner wall of the base housing at the upper end of the cyclone separator, with a curved semi-circular inner wall area of the flow guide element that is concave in sections, in relation to the inner volume of the lateral radius r formed by the flow guide element, said flow guide element having a helical section that is directly connected to the inlet opening.

• and
• wherein guide elements designed to displace the fins along a circular arc movement path are provided onto which the fins of the first wall and the fins of the second wall are mounted.
