ABSTRACT:
A special form of fluid cyclone in which the velocity energy in the exit fluid is converted into exit pressure thus permitting the device to discharge to atmospheric pressure or a higher pressure while a vacuum may exit in the central core of the vortex. The result is achieved by use of a curved passage at the exit which starts as a coaxial space and gradually expands and turns outward to become a circular space between two disks. The removal of reject material to atmospheric pressure with a vacuum at the core may be achieved by limiting the restriction in cross-section of the bottom core such that the pressure is atmospheric and allow it to leave through a space between the end of the cone and a blunt shaped surface. The above special form of fluid cyclone operates particularly well, because of reduced energy losses, when employed in a multiple arrangement in which the tangential velocity energy of fluid entering the barrel of the individual cyclone units is created by fluid flowing at larger radius such as to create a pattern of multiple vortex flow. The vortices are in a chamber providing a common inlet to a plurality of cyclone units with the vortices centering on the individual units. The special arrangement of fluid cyclones is in a geometry similar to that of a vortex trail with an even number of units of opposing vortex direction. The same type of arrangement; i.e. having all of the units discharge into a common chamber, leads to further energy recovery in fluid leaving the fluid cyclones.
