PCT No. PCT/FI94/00482 Sec. 371 Date Jul. 10, 1996 Sec. 102(e) Date Jul. 10, 1996 PCT Filed Oct. 25, 1994 PCT Pub. No. WO95/14535 PCT Pub. Date Jun. 1, 1995A method and apparatus for improving the separation efficiency of a cyclone separator intended for gaseous medium flows in which an incoming gaseous medium flow to be cleansed is directed into the cyclone separator through an inlet duct such that the incoming medium flow ends up in a downward, revolving flow movement inside the cyclone separator until the incoming medium flow reaches a bottom end of a conical lower part of the cyclone separator, and then becomes a revolving tornado flow that flows in a generally upward direction opposite to the direction of the downward, revolving flow movement. An outlet flow of cleansed gaseous medium is directed through a center pipe situated in the cyclone separator. A component-flow pipe is arranged in the center pipe such that the component-flow pipe has an inlet opening in a wall of the center pipe. A component flow of the incoming medium flow is passed from a location within the cyclone separator through the inlet opening in the wall of the center pipe into the component-flow pipe directed out of the component-flow pipe against the tornado flow such that the component flow disintegrates the tornado flow and thereby prevents solid matter from being carried along with the tornado flow through the center pipe into the outlet flow of the cleansed medium flow.
