Centrifugal separator

Claim 1

An improved centrifugal separator for gases having suspended liquid particles entrained therein comprising: a closed chamber, said chamber being defined by a generally cylindrical side wall and a pair of parallel oppositely disposed planar end walls, the axis of said cylindrical chamber being arranged substantially vertically; means including a port in the upper of said end walls for discharging gas from said chamber; means including a port in the lower of said end walls for discharging from said chamber liquid separated from a liquidgas mixture delivered to said chamber, said gas and liquid discharge ports being in substantially aligned relationship; a spiral Baffle disposed in said chamber between said end walls, said baffle being connected at a first end to said side wall and having a plurality of convolutions which define alternate venturi and diffusing sections for alternately accelerating and decelerating a liquid-gas mixture, said baffle venturi sections are aligned with contiguous convolutions closely spaced at one radial of the cylindrical chambers, the inner convolution of said baffle defining an open core which communicates with said discharge ports; and means including a supply port in said side wall adjacent the point of attachment of said baffle first end for supplying a liquid-gas mixture to said chamber, said supply port being intermediate the ends of said chamber.
