Patent ID: 8657908

Claim:
A gas cleaning separator for separating a flowable mixture of substances of different densities, the separator comprising: a housing defining an inner space, a rotor assembly for imparting a rotary motion onto said mixture of substances, the rotor assembly being located in said inner space and rotatable about an axis relative to the housing, wherein the rotor assembly comprises a first inlet for receiving said mixture of substances, a first outlet from which said substances are ejected from the rotor assembly during use, and a first flow path for providing fluid communication between the first inlet and first outlet, wherein the first outlet is positioned more radially outward from said axis than the first inlet; and a housing member located adjacent the rotor assembly, the housing member and the rotor assembly being spaced from one another so as to provide a first region therebetween on a first side of the housing member, said first region defining a first fluid flow route for fluid ejected from the rotor assembly; the housing member also being spaced from the housing so as to provide a second region therebetween on a second side of the housing member, said second region defining a second fluid flow route for fluid ejected from the rotor assembly; and wherein the rotor assembly comprises a second inlet which opens into said second region on said second side of the housing member, a second outlet positioned more radially outward from said axis than the second inlet, and a second flow path for providing fluid communication between the second inlet and the second outlet.
