Method and apparatus for improving the separation efficiency of a cyclone separator intended for gaseous fluid flows

In a method for improving the separation and cleansing efficiency of a cyclone separator intended for a gaseous medium flow in which the gaseous medium flow to be cleansed flows as a incoming medium flow into an interior of the cyclone separator through an inlet duct and flows in a revolving flow movement inside a substantially cylindrical upper part of the cyclone separator and an upper portion of a conical lower part of the cyclone separator, the revolving flow movement of the gaseous medium flow being changed in a lower portion of the conical lower part of the cyclone separator into a revolving tornado flow movement in an opposite direction to the direction of the revolving flow movement in the upper portion of the conical lower part of the cyclone separator, solid matter being separated from the gaseous medium in the cyclone separator whereby the gaseous medium from which solid matter is separated is directed from the cyclone separator through a center pipe, the improvement comprising the steps of:

• arranging a component-flow pipe to extend at least from an opening in a wall of the center pipe to a location within the center pipe,
• passing a component flow portion of the incoming medium flow from a location exterior of the center pipe and within the interior of the cyclone separator into the component-flow pipe, and
• directing the component flow from the component-flow pipe against the tornado flow such that the component flow disintegrates the tornado flow and prevents solid matter from being carried through the center pipe into an outlet flow of the cleansed gaseous medium.

A method for separating and cleansing a gaseous medium in a cyclone separator, comprising the steps of:

• directing the gaseous medium to be cleansed as a incoming medium flow into an interior of the cyclone separator through an inlet duct to cause the incoming medium flow to flow in a revolving flow movement inside a substantially cylindrical upper part of the cyclone separator and an upper portion of a conical lower part of the cyclone separator, the revolving flow movement of the incoming medium flow being changed in a lower portion of the conical lower part of the cyclone separator into a revolving tornado flow movement in an opposite direction to the direction of the revolving flow movement in the upper portion of the conical lower part of the cyclone separator,
• directing cleansed gaseous medium from which solid matter has been separated in the cyclone separator from the cyclone separator through a center pipe extending through the cylindrical upper part of the cyclone separator,
• arranging a component-flow pipe to extend at least from an opening in a wall of the center pipe to a location within the center pipe, and
• passing a component flow portion of the incoming medium flow from a location exterior of the center pipe and within the interior of the cyclone separator into the component-flow pipe, and
• directing the component flow from the component-flow pipe against the tornado flow such that the component flow disintegrates the tornado flow and prevents solid matter from being carried through the center pipe into an outlet flow of the cleansed gaseous medium.

A method for improving the separation efficiency of a cyclone separator intended for gaseous medium flows, comprising the steps of:

• directing an incoming gaseous medium flow to be cleansed 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,
• directing an outlet flow of cleansed gaseous medium through a center pipe situated in the cyclone separator,
• arranging a component-flow pipe in the center pipe such that the component-flow pipe has an inlet opening in a wall of the center pipe,
• passing a component flow of the incoming medium flow from a location within the cyclone separator through the inlet opening in the wall of the center pipe into the component-flow pipe, and
• directing the component flow out of the component-flow pipe against the tornado flow that has been formed 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.
