Nozzle for Hiride Mixing Table

The MPD Nozzle, developed using CFD(Computational Fluid Dynamics) modeling,utilizes a converging body-throatdesign to generate a fluid jet and vacuum below the inlet hopper. The geometryensures proper operation with inlet pressures as low as 20 psi reducing both pumploads and pumping costs. The efficient nozzle design converts the pressure headto velocity head generating a near perfect vacuum of 26.8 in Hg (90.8 KPa.) atthe solids/liquids induction interface. In this void space, first stage mixingoccurs as the induced product is entrained in the motive fluid. The TMDDiffuser, also developed using CFD modeling, uses unique internal geometry tocreate the optimum mixing environment. This is done by creating multiple lowpressure volumes that cause jet degradation and create vortex mixing.

It’s efficient sloped inlet and throatdesign, followed by high angle mixing chamber and discharge throat/diffusersections create two additional re-circulation/mixing zones. This is extremelybeneficial when dealing with materials that are difficult to mix. This design ensuresthat pressure and flow losses are minimized while vacuum and throughput are optimized.This is achieved while the mixing energy is maintained at 92 kW/m3/hr, the lowest of any comparable unit.As a result, pump requirements and energy consumption are reduced.

The eductor also has a 2-inch (51 mm.)port installed on the inlet of the mixer body for the addition of liquidproducts from drum, bulk tank or tanker sources. Liquids with a viscosity similarto water can be added at a rate of up to 108 USGPM (410 l/m) under vacuumwithout a pump. Induction rates will vary depending on:

1. Length of pipe/hose run,

2. Location of inlet, with respect tofluid (elevation)

3. Density and viscosity of fluid added.
