Abstract:
A method for separation or other treatment of fluids including liquids, liquid-liquid mixtures, gases, or liquid-gas mixtures and of materials contained in said fluids including solids, other particles, or gelatinous or viscous materials, comprising:a centrifugal separator with an outer shell operable to receive a plurality of receptacles; the centrifugal separator's outer shell having an interior and an exterior; each receptacle having an outermost hard or rigid layer, a middle flexible and/or compressible layer and an innermost hard or rigid layer; the innermost hard or rigid layer of each receptacle being hopper-shaped or trumpet-shaped, whose broadest open end presents to the interior of said centrifugal separator's outer shell, and whose sloping receptacle walls converge outwardly to meet at a relatively smaller opening projecting through the exterior of said centrifugal separator's outer shell; the flexible and/or compressible middle layer of each receptacle is shaped to fit within and be loosely connected to the hard or rigid outermost layer of each receptacle; the innermost hard or rigid innermost layer of each receptacle fits within and is loosely connected to the middle flexible and/or compressible layer of each receptacle, such that said innermost hard or rigid layer is free to be vibrated in various ways and move various directions within the flexible and loosely connected containment supplied by the middle flexible and/or compressible layer; and a means for generating or inducing vibration on, against and/or in the innermost hard or rigid layer, wherein vibratory motion thus applied to the innermost hard or rigid layers of the receptacles received on the outer shell of the centrifugal separator decreases the friction between the sloped, converging walls of the innermost hard or rigid layers of the receptacles and the materials being centrifugally thrown against those wails, such that those materials are thereby freed from sticking to the sloped, converging walls and thus can travel further outwards along the sloped, converging walls and deeper into the increasingly small volume of space presented by the sloped, converging walls, thereby applying additional physical compression to said materials due to the converging of the walls, and thus compelling additional or enhanced removal of fluid from these materials, as a means for either increasing the separation of lighter fluid from heavier fluid, or for improving the removal of additional fluid from heavier fluids resulting in their increased dryness, depending on the goal of a particular centrifugal process.
