A rotary slurrifier apparatus for creating a slurry of small particles of at least one first fluid, suspended in a continuous phase of an essentially mutually insoluble second fluid, and comprising:
- at least one source of first fluid, and a separate source of second fluid, all of said first fluids being largely mutually insoluble in said second fluid;
- a spinning disc shell comprising at least one pair of cylindrical spinning discs for each said first fluid, each pair of spinning discs comprising a lower spinning disc, and an upper spinning disc;
- disc drive means for rotating the spinning disc shell, and all pairs of spinning discs, at high angular velocity, about a vertical spinning disc centerline of rotation and symmetry;
- a rotating cavity shell, comprising a number of pairs of enclosed cylindrical impact cavities, equal to the number of pairs of spinning discs, each pair of impact cavities being flow connected together at their outer radius;
- cavity shell drive means for rotating the cavity shell at a high angular velocity about a vertical cavity shell centerline of rotation and symmetry;
- wherein each pair of flow connected impact cavities comprises a cylindrical entry plate, enclosing the bottom of the lower impact cavity;
- and a cylindrical exit plate, enclosing the top of the upper impact cavity;
- and a cylindrical separator block, separating the upper and lower impact cavities, and comprising flow passages, at the outer radius, connecting the lower impact cavity to the upper impact cavity of the pair;
- wherein, for each pair of flow connected impact cavities, the inner radius of the cylindrical exit plate is greater than the inner radius of the cylindrical entry plate, and the inner radius of the cylindrical separator block is less than the inner radius of the cylindrical entry plate;
- wherein the inner radius, of the cylindrical entry plate, of each pair of flow connected impact cavities, above a similar pair of impact cavities, is no less than the inner radius of the cylindrical exit plate of the flow connected pair of impact cavities next below;
- wherein said rotating cavity shell further comprises a slowdown reaction turbine enclosed cavity, above the uppermost flow connected pair of impact cavities, and comprising a cylindrical entry plate, whose inner radius is no less than the inner radius of the cylindrical exit plate of that uppermost flow connected pair of impact cavities;
- and comprising symmetrical reaction turbine guide vanes, at a radius greater than the inner radius of the cylindrical entry plate of the reaction turbine cavity;
- the flow direction of the reaction turbine guide vanes is principally opposite to the direction of rotary motion of the cavity shell;
- the reaction turbine cavity further comprising an upper enclosing cylindrical plate whose inner radius is less than the inner radius of the cylindrical entry plate of the lowermost flow connected pair of impact cavities;
- a stationary fluid collector pan positioned to collect fluid flowing through said reaction turbine guide vanes;
- a stationary bracket means for supporting, the spinning disc shell and disc drive means, and also the rotating cavity shell and cavity shell drive means, so that the spinning disc centerline of rotation is coincident with the cavity shell centerline of rotation;
- wherein the direction of rotation of the spinning disc shell is opposite to the direction of rotation of the cavity shell;
- a number of separate first fluid delivery means for delivering first fluid portions on to top surfaces of said pairs of spinning discs, equal to the number of separate first fluids, each said separate fluid delivery means delivering first fluid portions from but one separate source of first fluid, and on to the top surfaces of pairs of spinning discs;
- wherein said stationary support bracket means further aligns each pair of flow connected impact cavities with one pair of spinning discs receiving first fluid portions from but one source of first fluid, and further aligns each pair of flow connected impact cavities so that first fluid portions spun off the top surfaces of the aligned pair of spinning discs will enter the flow connected pair of impact cavities;
- wherein each two common first fluid portions, delivered onto the two top surfaces, of each pair of spinning discs aligned with a pair of flow connected impact cavities, are essentially equal fluid portions, and are delivered essentially concurrently onto the two top surfaces;
- whereby centrifugal force, created by disc rotation, will cause those common first fluid portions, delivered onto the top surface of each pair of spinning discs, to be thrown off the outer radius of each spinning disc, and into the aligned flow connected impact cavities;
- wherein the outer radii, of the upper and lower spinning discs of each pair, are equal and are less than the inner radius of the cylindrical entry plate, of that flow connected pair of impact cavities, with which that pair of spinning discs is aligned;
- second fluid delivery means for delivering second fluid portions, from said source of second fluid, on to the top surface of the cylindrical entry plate of the bottommost flow connected impact cavity pair;
- whereby centrifugal force, created by cavity shell rotation, will cause those second fluid portions, delivered on to the top surface of the cylindrical entry plate of the bottommost flow connected impact cavity pair, to form into a pair of cylindrical second fluid masses, occupying all or a portion of the bottom pair of flow connected impact cavities;
- and further whereby continued delivery of second fluid portions, on to the top surface of the cylindrical entry plate, of the bottommost flow connected impact cavity pair, will cause delivery of portions of second fluid upward, past the inner radius of the cylindrical exit plate of the bottommost impact cavity pair, and past the inner radius and on to the top surface of the cylindrical entry plate of the next above flow connected impact cavity pair, whereby the next above pair of impact cavities also becomes occupied, in whole or part, by a pair of rotating cylindrical masses of second fluid;
- and additionally whereby continued delivery of portions of second fluid, on to the top surface of the cylindrical entry plate of the bottommost flow connected impact cavity pair, will cause a continued delivery of second fluid portions upward, into and through each successive pair of flow connected impact cavity pair above, so that all impact cavity pairs become occupied by rotating cylindrical masses of second fluid;
- and this continued upward delivery of second fluid continues into the slowdown reaction turbine cavity, and out of the reaction turbine cavity, via the reaction turbine flow directors and into the stationary collector pan;
- finally whereby first fluid portions are thrown into the counter rotating cylindrical masses of second fluid, in the impact cavities, and the high relative velocity of impact between first fluid and second fluid atomizes the first fluid into many small particles, suspended in a continuous phase of the mutually insoluble second fluid, and this resulting slurry is slowed down and discharged into a stationary collector pan.
