Abstract:

The present invention provides for discharge (exit) ports for exit fluid flow disposed at or adjacent to one another on one end of a vortex separating body; an inlet port(s) disposed at one end of a separating body having discharge (exit) ports for exit fluid flow disposed at or adjacent to one another at an opposite end of the separating body; increased separation efficiency; solid mass separated per unit energy expended; a body that is predominantly cylindrical in shape that can be made inexpensively from standard sizes of pipe or tubing; a device that is predominantly cylindrical in shape so that the separation (vortex) length of the device can be changed simply by installing or removing sections of pipe or tubing; a device which promotes smooth rotational flow within the vortex region, therefore affecting an efficient separation of particles carried by the transporting fluid therein and reducing the pressure and/or energy required to move the fluid through the device; a device with entrance and especially with exit ports that are predominantly closed to the atmosphere so that exit fluid can be cleanly and efficiently transported from the device to a subsequent location or an additional device, especially another separator.
