ABSTRACT:
An improved type of centrifugal separator for separating liquids such as oil and/or water from a mixture of gas and liquid. It consists of an upright cylindrical shell divided by transverse dividers into three chambers. The mixture of gas and liquid is introduced through a tangential diverter into the lower chamber to produce a high velocity vortex of gas and liquid. A central axial vortex tube penetrates and is sealed through both transverse dividers. This vortex tube is comprised of two spaced longitudinally aligned portions which define a gap between them. The gap is positioned inside the central chamber. The upper end of the vortex tube extends into the top chamber and is sealed into a first mist extractor. The lower end of the vortex tube extends into the lower chamber.
Due to the vortex action the liquid is thrown outwardly against the inner wall of the shell, the gas forming a high velocity vortex column along the central axis of the shell. This gas column moves upwardly through the central axial vortex tube. Entrained liquid is thrown outwardly against the wall of the tube by centrifugal action and is drawn into the central chamber through the gap between the two sections of the vortex tube. The gas continues to move upwardly into the first mist extractor. Here it is passed through a tortuous passage between elongated vertical obstacles such that the liquid is scrubbed out against these surfaces. The gas then passes through a second mist extractor, and essentially liquid free gas passes out an opening in the top of the shell.
