Cyclonic elevator and method for using same

摘要

A cyclonic elevator tube comprising a manifold which supplies fluid under pressure via an annular transition ring with multiple, circumferentially spaced jet orifices. These orifices are set at inwardly and circumferentially directed compound angles for ejecting vortex jets of pressurized fluid through the elevator, to ultimately cause transportation of fluid material through the tubes. This apparatus comprises: a cylindrical chamber; a plurality of helically shaped venturi tubes spaced around the internal circumference of the chamber; a manifold connected to the inlet ends of the venturi tubes; and a high pressure gas supply connected to the manifold. The helix can be right or left handed and preferably the venturi tubes extend for less than one turn of the helix. The angle that the tangent of the helix makes with the longitudinal axis of the chamber is between 1° and 89°. The internal circumference of the chamber may be larger at the inlet end than at the outlet end.

主权项

1. An apparatus for pumping fluid comprising:
a) a cylindrical chamber having an internal circumference, a longitudinal axis, an inlet flange and an outlet flange; said flanges being at 90 degrees to said cylindrical chamber; b) an annular manifold attached to said inlet flange; c) an annular Venturi section within said manifold having a wall, a second internal circumference, an inlet end, an outlet end and a second longitudinal axis; said second longitudinal axis being in line with said longitudinal axis; d) a plurality of Venturi tubes within said wall spaced around said second internal circumference; each of said Venturi tubes having a helical shape; each of said Venturi tubes having an inlet diameter at said inlet end and an outlet diameter at said outlet end; said inlet diameter being larger than said outlet diameter; said manifold connected to said inlet ends; and e) a high pressure gas supply for supplying gas under high pressure, connected to said manifold.
