THE SPINTOP™ HYDROCYCONE, A NON-PLUGGING HYDROCYCLONE

INTRODUCTION:

NEW LIQUID/SOLIDS SEPARATION:

Hydrocyclones are density separators that convert pressure energy into rotational momentum. The rotational momentum provides the centrifugal force to separate solids from a primary liquid. Separation efficiency is determined by the Hydrocyclone geometrical parameters. The interaction between parameters dictate the Hydrocyclone efficiency. It is essential that the geometry of each internal component is designed to promote a smooth transition in maintaining laminar flow.

The Spintop™ Hydrocyclone has four outstanding features that are unique to conventional Hydrocyclone. (1) Involuted feed, (2) a Bell shaped Vortex Finder, (3) a Solid Center Core and (4) a Parabolic shaped body.

FEATURES:

Generally, typical hydrocyclone have a tangential feed inlet and two outlets; one for the concentrated solids (under-flow) and one for the relatively clean liquid reporting out the Vortex Finder Tube (overflow)

OPERATION:

In operation, a pressurized slurry is fed to the Hydrocyclone and the centrifugal force generated causes the heavier suspended solids to move toward the wall while the radial velocity forces the liquid and lighter gravity solids to move inward toward the center axis. Primary and secondary vortex develops. The primary vortex carries the solids to the apex. The apex orifice permits the heavier solids and a small amount of the liquid to be discharged. Air is drawn through the apex and a secondary developing vortex carries the cleaned primary liquid and light gravity solids out through the Vortex Finder Tube.

(1) The full involuted feed provides a smooth transition from pressure energy to rotational momentum. The rotational flow does not collide with the feed inlet flow. This eliminates the turbulence that influences the rate of sedimentation.

(2) The bell shaped Vortex Finder Tube increases acceleration to the rotating fluid at a critical moment. The acceleration rapidly moves the heavier solids toward the Hydrocyclone walls, This reduces the possibility of mixed density solids leaking or short circuiting through the overflow

(3) The Solid Center Core attached to the entrance to the Vortex Finder Tube provides flow stability between the primary and secondary vortices. The Solid Center Core replaces the unstable and fluctuating air core. The instability of the air core degrades the symmetry and equilibrium of the flow-field. The Solid Center Core promotes a more constant rotational velocity and keeps the centrifugal force from degrading.

(4) The Parabolic Shaped Body of the Hydrocyclone provides a more gentle slope from the cylindrical section to the apex orifice. The large cross-sectional area of the Parabolic Shaped Body contributes to a stable laminar flow and a reduction in plugging.
