Radial Eductor For Submerged Mixing Applications

TANK MIXING EDUCTOR FOR DRILLING RIG FLUID SYSTEMS, BLENDING PLANTS AND TRANSPORT VESSELS

The Radial Eductor is designed from the Bernoulli Principle of; when pressure is high, velocity is low and inversely when velocity is high, pressure is low.

A pressurized motive fluid flow is converted to velocity opposite the nozzle orifice, creating a low pressure region that radially draws in a secondary fluid through the helical inductors from the surrounding fluid. The geometric arrangement of the inductors promotes a spinning flow

as the secondary fluid interacts with the primary fluid in the mixing chamber of the radial eductor. Large and small scale vortices are generated, producing dispersion as the blended flow stream issues from the diffuser section of the Radial Eductor.

The Radial Eductor is a high volume EDUCTOR using the LOBESTAR® power jet to produce high turbulence. A centrifugal pump is used to pressurize the Radial Eductor. Static pressure is converted to high velocity as the slurry passes through the jet nozzle orifice. The high velocity causes a region of low pressure. The motive flow pumped through the jet nozzle draws in three times the volume pumped. Example: The flow rate of an RE-2 (2") Model has a 7/8" nozzle orifice is 116 gpm @ 40 psi. The total mixed fluid is 464 gpm. The motive flow rate of the jet nozzle draws three times it’s volume through the inductors. This interaction prevents solids from settling at the bottom and the corners of the tank.

The delivery of drilling fluids to a rig site without loss of product is a dramatic savings in drilling fluid materials, rig time and man/hours exposure to toxic fumes during tank cleaning.

No more arriving at the rig site with part of the drilling fluid settled in the tank corners and on the tank floor. This can be a quadruple cost 1) rig time to get the mud weight back up to the desired density 2) cost for barite that you have already paid for once 3) boat company charges for cleaning out tanks 4) disposal cost.

MANY TANK ARRANGEMENTS ARE POSSIBLE, SEE EXAMPLES BELOW

Radial Eductor Illustrated With Vertical Agitator

The centrifugal motion generated by an agitator flings the solids toward the tank corners. The Radial Eductor produces a high velocity plume that circulates and suspends the mixture eliminating sediment built-up on the tank floor and in the corners.
