A method for accelerating the transfer of media between materials reacting in a fluidized bed in a centrifuge. The rotating fluidized bed increases the relative boundary layer velocities of the phases and assists in the transfer of material across the interface.

Process for accelerating the transfer of media in a fluidized bed

A device for the acceleration of a reaction between media of solid and liquid phases comprising means for forming a fluidized bed, wherein the solid medium is held suspended in the liquid medium, and means for generating a centrifugal field for acting on the fluidized bed. The fluidized bed is defined between a rotating sieve drum and a first cylindrical sieve which is located within the sieve drum.

Apparatus to accelerate the transfer of material between two media

Agitator elements are provided in an apparatus and a process for the transport of heat and material between finely grained solid particles and a flow of carrier gas in a rotating fluid bed in order to prevent settling of coarse particles or agglomerates. The agitator elements are immersed into the fluid bed and move at a velocity different from that of the revolving fluid bed.

Apparatus and process for drying finely grained solid particles

A process for the dewatering and particle classification of solids from suspensions, e.g. coal from a slurry in which the coal is transported, makes use of a dewatering centrifuge having two frustoconical centrifuge drum sections of different inclinations such that in a first filtering zone the particles are preliminarily dewatered and then pass by automigration to the next centrifuge drum at which further dewatering takes place. The suspension on the first sieve surface forms a thin layer classification zone having a thickness up to 5 mm and in which the coarse fraction is retained while the fine fraction is passed. The coarse fraction automigrates to the next sieve surface where it is dewatered and the fine fraction separated out in the thin layer classifying zone is then filtered under pressure in a subsequent stage.

Process and apparatus for the dewatering of solids in suspension

A rotary filter has a pressure vessel and a rotor from which a plurality of filter cells are suspended from outer portions of the rotor so that they clear a conveyor located proximal to the axis of rotation and upon which the filter cake is removed. Conduits are connected to the filter cells from a single distribution head for initially evacuating the cells in the filter stage and thereafter pressurizing the cells to dislodge the filter cake while the vessel remains under pressure. The filter cells can have the filter surfaces extending generally in axial planes or in axially spaced relationship in planes wherein a plurality of angularly spaced filters extend generally radially from respective filtrate conduits running axially along the outer part of the rotor.
