High efficiency cyclone separator

A cyclone fluid separator comprising:

• deflecting means for receiving and generating spiral motion in a fluid for centrifugally separating substances and materials in the fluid having a mass and density per unit volume greater than the fluid;
• container means for confining said spiral motion, said container means having two open ends, one of said ends being connected to and closed by said deflecting means, the other of said ends being oppositely disposed said deflecting means and through which opening unwanted substances and materials of a mass and density per unit volume greater than the fluid may exit;
• conduit means located on the center line of said container means and passing through said deflecting means and having one end centrally located within said container means and the other end located external to said container means through which the fluid separated from the unwanted substances and materials may exit;
• a flange attached adjacent to said one end of said conduit means and projecting outwardly from the exterior surface thereof, said flange having a surface thereon for deflecting longitudinal flow of fluid adjacent the surface of said conduit means outwardly toward the interior surface of said container means where the spiral fluid motion causes the unwanted materials and substances to contact the container surface and exit through said opening in said container and whereby the fluid separated from the materials and substances forms a vortex which exits through said fluid conduit;
• and
• a diffuser collar having two oppositely disposed ends and connected to said flange in a manner leaving a circumferential opening between said flange and said collar, said collar having a flared end adjacent said flange, which flared end has a diameter substantially the same as said flange to produce a pressure difference through said circumferential opening to force unwanted substances and materials radially outward through said circumferential opening to obtain further separation of the unwanted substances and materials from the fluid vortex flowing through said conduit means.

An improved cyclone separator of the type having a fluid deflector comprising means adapted to receive a fluid and impart circular motion thereto, and wherein the fluid deflector is attached to and closes the base of a conical container, which container has an outlet at the apex thereof from which unwanted materials and substances of a mass and density greater than the fluid may exit and be removed from the fluid and wherein a fluid conduit is located along the center line of the conical container and passes through the fluid deflector which conduit has one end centrally located within the conical container and the other end located external thereto, and wherein an axial vortex of fluid separated from the unwanted materials and substances is formed in the container, which vortex spirals into the one end of the fluid conduit and exits from the other end, the improvement comprising:

• an interceptor ring having outer and inner circumferences, the inner circumference mating with and being circumferentially attached externally to the fluid conduit near the one end of the fluid conduit centrally located within the conical container, said ring extending radially outward from said inner circumference to said outer circumference to intercept fluid which flows longitudinally along the outer surface of the conduit and deflect the longitudinal flow radially outward from the center surface of the conduit whereby unwanted materials and substances are impinged against the conical container interior surface and exit through the apex opening therein;
• and
• a diffuser collar substantially uniformly spaced from the fluid conduit and surrounding the one end of the fluid conduit, said diffuser collar having two ends, one end being attached to said outer circumference of said interceptor ring and having spiral vanes which spiral radially inwardly from said outer circumference to contact and connect to the outer surface of the fluid conduit adjacent said interceptor ring, the other end of the diffuser collar being open, whereby the vortex of fluid which spirals toward the one end of the fluid conduit has the outer layer skimmed therefrom by the uniform space between the fluid conduit and said diffuser collar, which skimmed layer spirals between said diffuser collar and the fluid conduit and is intercepted by said spiral vanes and ejected outwardly into the conical container.
