Abstract:
A centrifuge for removing more dense material from a fluid medium, comprising:a fluid separation wall placed within a non-rotating sleeve to form a containment zone therebetween; the containment zone operable to receive a portion of the fluid medium having a greater concentration of the more dense material; the fluid separation wall including an inner surface, a middle section, and an outer surface; the fluid separation wall aligned generally parallel to an axis of rotation and operable to rotate around the axis of rotation; the fluid separation wall including a receptacle defined in part by a respective geometry formed on the inner surface and a respective shape formed in the middle section to form a void space between the inner and outer surface; the receptacle operable to aid in separation of the more dense material from the fluid medium; the respective shape including a wall shape selected from the group consisting of a curved wall, a compound curved wall, an asymmetric shaped wall, an irregular shaped wall, and any combination thereof; the respective geometry selected from the group consisting of a triangle, a square, a rectangle, a trapezoid, a diamond, a rhombus, a pentagon, a hexagon, an octagon, a circle and an oval; at least one flow path extending through the fluid separation wall from the void space to the outer surface; and the flow path operable to transport the more dense material to the containment zone.
