A cyclone separator provided with a tube with an axial inflow opening and an axial outflow opening, a stationary swirl body arranged in the tube, designed for imparting a spiraling movement to an axially directed gas liquid flow entering the tube in use, while in the case wall of the tube, a slot has been provided for discharging from the inside space of the tube liquid in the gas/liquid flow thrown outwards, while the slot runs in a spiral-shaped path over the case wall of the tube and/or wherein in the case wall of the tube, downstream of the at least one slot, at least one bypass opening is provided, while means are provided for creating, at the location of the at least one bypass opening, a reduced pressure in the tube relative to the pressure prevailing out-side the tube. The invention also provides a liquid collecting box with such cyclone separator and a pressure vessel provided with such liquid collecting boxes.

The invention claimed is: 1. A cyclone separator provided with a tube with an axial inflow opening and an axial outflow opening, a stationary swirl body arranged in the tube, designed for imparting a spiraling movement to an axially directed gas/particles flow entering the tube in use, while in the case wall of the tube, a slot is provided for discharging from the inside of the tube particles in the gas/particles flow that has been slung radially outwards under the influence of the centrifugal force prevailing in the spiraling flow, wherein only one slot is provided, while the slot runs in a spiral-shaped path over the case wall of the tube, characterized in that the particles are liquid particles, wherein downstream of a downstream end of the spiral-shaped slot, at least one bypass opening is provided in the case wall of the tube, while on the inside of the tube, means are provided for creating in the tube, at the location of the at least one bypass opening, a reduced pressure relative to the pressure prevailing outside the tube at the location of the at least one bypass opening. 2. A cyclone separator according to claim 1, wherein the spiral of the slot extends clockwise around the central axis of the tube while, in use, the spiraling gas/liquid flow rotates counterclockwise around the central axis of the tube, or vice versa. 3. A cyclone separator according to claim 1, wherein the spiral-shaped slot extends over substantially 180 degrees around the tube surface. 4. A cyclone separator according to claim 1, wherein the angle of pitch of the spiral-shaped slot is in the range of 30-60 degrees, more in particular is approximately 45 degrees. 5. A cyclone separator according to claim 1, wherein upstream of the swirl body, a secondary gas inflow opening is provided in the case wall of the tube, to which, on the inside of the tube, a secondary gas pipe is connected which terminates in a chamber provided in a core of the swirl body, the chamber being provided with at least one secondary gas outflow opening. 6. A cyclone according to claim 5, wherein the swirl body is provided with a number of secondary gas outflow openings which have been provided upstream of an axially downstream end of the swirl body, preferably between swirl blades provided on the core of the swirl body. 7. A cyclone separator according to claim 5, wherein the secondary gas inflow opening lies in the same axial center plane through the tube as the center of the slot. 8. A liquid collecting box provided with a number of cyclones according to claim 1, wherein the liquid collecting box is provided with a liquid discharge duct. 9. A pressure vessel provided with an inlet for a gas/liquid flow and a discharge for gas and a discharge for liquid, while between the inlet and the discharge for gas, a number of liquid collecting boxes according to claim 8 are arranged, while the liquid discharge ducts of the liquid collecting boxes are in communication with the discharge for liquid in the vessel. 10. A cyclone separator provided with a tube with an axial inflow opening and an axial outflow opening, a stationary swirl body arranged in the tube, arranged for imparting a spiraling movement to an axially directed gas/liquid flow entering the tube in use, while in the case wall of the tube at least one slot is arranged for discharging from the inner space of the tube liquid in the gas/liquid flow that has been slung radially outwards under the influence of the centrifugal force prevailing in the spiraling flow, characterized in that in the case wall of the tube, downstream of the at least at least one slot, at least one bypass opening is provided, while on the inside of the tube means are provided for creating in the tube, at the location of the at least one bypass opening, a reduced pressure relative to the pressure prevailing outside the tube at the location of the at least one bypass opening. 11. A cyclone separator according to claim 10 wherein the means for creating a reduced pressure comprise an inner ring which is provide upstream of the bypass openings on the inside surface of the case wall, while an inside diameter of the inner ring is smaller than the inside diameter of the tube. 12. A cyclone separator according to claim 11, wherein the inside diameter of the inner ring is 0.8 of the inside diameter of the tube. 13. A cyclone separator according to claim 10, wherein entry-prevention means are provided, designed for preventing the liquid from reentering from the outside of the tube via the bypass openings to the inside of the tube. 14. A cyclone separator according to claim 13, wherein the entry-prevention means comprise a ring or collar which is provided on the outside surface of the case wall and which extends in an imaginary plane intersecting the central axis of the tube perpendicularly, and located at an axial position between a downstream end of the spiral-shaped slot and upstream of the bypass openings, while the inside diameter of the respective ring or collar corresponds to the outside diameter of the tube. 15. A cyclone separator according to claim 13, wherein the entry-prevention means comprise a collar, directed radially outwards, around the or each by pass opening. 16. A liquid collecting box provided with a number of cyclones according to claim 10, wherein the liquid collecting box is provided with a liquid discharge duct. 17. A pressure vessel provided with an inlet for a gas/liquid flow and a discharge for gas and a discharge for liquid, while between the inlet and the discharge for gas, a number of liquid collecting boxes according to claim 16 are arranged, while the liquid discharge ducts of the liquid collecting boxes are in communication with the discharge for liquid in the vessel.
