Cyclonic fluid separator equipped with adjustable vortex finder position
A cyclonic fluid separator for separating one or more condensable components, such as water, and/or solids, such as smoke or sand particles, from a fluid mixture has a tubular housing having a fluid inlet section in which the fluid mixture is accelerated to a supersonic velocity and thereby expanded and cooled such that condensable components condense and/or solidify, one or more wings for inducing the fluid mixture to swirl within a central section of the tubular housing, a fluid separation section in which a tubular vortex finder is movably arranged, a condensables enriched fluid outlet which is connected to an annular space surrounding the tapered tubular vortex finder and a condensables depleted fluid outlet which is connected to the interior of the tapered tubular vortex finder. The vortex finder may be movable in a radial and/or longitudinal direction within the housing to align the entrance of the vortex finder with the centre of rotation of the swirling fluid, which center of rotation may be unaligned to and/or spiral about the central axis of the tubular housing as a result of the radial fluid displacement by the wing(s).
1. A cyclonic fluid separator for separating one or more condensable components and/or solids from a fluid mixture, the separator comprising a tubular housing, which comprises:
a fluid inlet section comprising a nozzle for accelerating the fluid mixture to a supersonic velocity to expand and cool the fluid mixture such that one or more condensable components are liquefied and/or solidified;
one or more wings for inducing the cooled fluid mixture to swirl within a central section of the tubular housing;
a separation section, which is located downstream of the central section and in which a tubular vortex finder is arranged;
a condensables enriched fluid outlet which is connected to an annular space between the outer surface of the tubular vortex finder and the inner surface of the tubular housing; and,
a condensables depleted fluid outlet which is connected to the interior of the tubular vortex finder;
in which the tubular vortex finder is movable in a longitudinal and radial direction relative to a central axis of the tubular housing.
2. The cyclonic fluid separator of claim 1 , wherein the tubular housing is bendable such that the vortex finder is movable in a radial direction relative to the direction of the central axis of the inlet section of the tubular housing which central axis is curved as a result of the bending of the tubular housing.
3. The cyclonic fluid separator claim 1 , wherein one or more wings for inducing the fluid to swirl within a central section of the tubular housing are mounted on a carrier body which is co-axial and rotatable relative to a central axis of the central section of the tubular housing.
4. The cyclonic fluid separator of claim 1 , wherein the tubular vortex finder is tapered such that the interior of the tubular vortex finder has a gradually increasing cross-sectional area in downstream direction.
