In a separator, a vapor-liquid mixture is passed upwardly through a pipe over an annular arrangement of curved vanes which whirl the mixture and effect the separation of its vapor and liquid components as it continues to flow upwardly above the vanes. Viewed in vertical section, each vane has a curved cross-section with its radius of curvature increasing from its radially inner end to its radially outer end. The vanes have the form of a section of the outer surface of a right circular cone whose axis extends transversely of the axis of the pipe containing the vanes and whose height is less than the diameter of the portion of the pipe containing the vanes.

A separator for dividing a liquid-vapor mixture, such as a steam-water mixture, into its liquid and vapor components, comprising a vertically extending first pipe arranged to convey the liquid-vapor mixture from a source, a central body positioned within and spaced inwardly from said first pipe and extending in the axial direction of said first pipe, a plurality of vanes located within the extending approximately radially of said first pipe below the upper end thereof, said vanes arranged in spaced relationship to one another in an annular formation extending between said central body and said first pipe, said vanes arranged to whirl the liquid-vapor mixture within said first pipe as the mixture flows upwardly about said vanes, a vertically extending second pipe located within said first pipe with the lower end thereof spaced upwardly above said vanes and arranged to receive the vapor component of the mixture separated by the whirling action imparted to the mixture by said vanes, said second pipe being substantially co-axial with said first pipe, the upper end of said second pipe extends upwardly from the upper end of said first pipe, wall means laterally enclosing said first pipe and forming an annular outlet chamber therebetween for the separated liquid component and the upward end of said first pipe above the lower end of said second pipe being perforated to flow the separated liquid component into the outlet channel, the upper end of said second pipe being located above said wall means wherein the improvement comprises that each of said vanes has an upper edge and a lower edge relative to the vertical direction of said first pipe and an inner edge contacting said central body and an outer edge contacting the inner surface of said first pipe, each of said vanes has a curved cross-section in the axial direction of said first pipe extending from the lower edge to the upper edge thereof with the radius of curvature of each of said vanes increasing from the inner edge thereof to the outer edge thereof, each of said vanes being formed in the shape of a portion of the outer surface of an imaginary cone having a top angle in the range of 50°to 70°with the axis of the cone arranged transversely of the axis of the first pipe and the apex of the cone located inwardly of the inner surface of said first pipe, and the upper edge of said vanes is disposed approximately horizontally and the lower edge of said vanes slopes upwardly in the inward direction.
