Mixing Equipment
Chaos Mixer
The Mixing Assembly is composed of a manifold style feed inlet, two nozzle disc, and a mixing chamber with a uid outlet. The insert Trinity Nozzles in each disc are geometrically opposed to each other and are located on each end of the Mixing Chamber.
In operation, a pressurized liquid enters the manifold and is split into two streams, whereby each high velocity stream emanates from the Trinity Nozzles, rotating counter to each other, colliding in the center of the Mixing Chamber. The kinetic energy and dynamic shear imparted at the point of impingement generates rapid mixing, instant hydration and uniform dispersion.
The Chaos Mixer features a novel mixing design in splitting a liquid stream through opposing Trinity Nozzles to generate interfacial, dynamic shear in a mixing chamber (see illustration 2).
There are multiple applications for the Chaos Mixer by exchanging the insert Trinity Nozzles. The Nozzles can be replaced with special Vortex generating Nozzles to produce partial, hydrodynamic cavitation. By producing cavitation, the bond between the liquid carrier and the suspended solids can be broken. Breaking the bond between the liquid phase and the suspended solids provides utilization in the following applications: Drill cuttings washing, soil washing, degassing liquids. In addition to these applications, the Chaos Mixer can be utilized as a pretreatment for centrifuges, lter presses and hydrocyclones.
Filtration Enhancement Through Hydraulic Shear
Compatible Components Corporation has successfully applied hydraulic shear technology to aqueous slurries before filtration. This technique allows the fluid to flow more freely and uniformly while the suspended solids are retained. In addition to an increase in filterability, a more uniform cake has been observed which reduces the possibilities of "bleed through". An even and uniform cake reduces filter aid usage and eliminates the need for a downstream Guard Filter.
Particles suspended in an aqueous slurry have a thin film formed on their surfaces due to a positive/negative relationship between liquid (+) and solids (-). Often, this film absorbs large amounts of water on the surface area of the particle, and a gelatinous mass forms and surrounds the particle. This liquid/gelatinous encasement increases fluid flow resistance.
The shearing stress imparted in the mixing chamber of the Chaos Mixer develops velocity forces at the solid/liquid interface resulting in a reduction of surface tension, lower viscosity, and gel strengths which in turn improves flow rate and filterability.
