摘要： Tendrillar carbonaceous material is used as a fluidization aid for fluidized beds. The tendrillar carbonaceous material can be used to fluidize cohesive solids. Further, it can be used to improve fluidization of particulate solids by reducing entrainment, eliminating bubbling, and/or eliminating channelling. The tendrillar carbonaceous material can be a fibrous, particulate carbonaceous material comprising carbon fibers and a ferrous group metal component dispersed throughout the carbon fibers as nodules. The tendrillar carbonaceous material has a bulk density of from about 0.04 to about 0.7 g/cm.sup.3 and comprises an agglomeration of tendrils having a diameter of from about 0.01 to about 1 micron and a length to diameter ratio of from about 5:1 to about 1000:1.

摘要： Porous, moisture-containing materials are dried in a fluidized bed reactor. The moisture content of both the underflow and carryover products from the dryer are controlled by introducing hot gases into the freeboard region above the fluidized bed. One or more tuyeres of extended length with ports at a level above the fluidized bed in the freeboard regin may be employed to admit hot gases directly into the freeboard region from the reactor windbox without traversing the fluidized bed. Alternatively, a valved conduit may be employed extending through the refractory dome or gas distributor to regulate gas flow between the windbox and the freeboard region.

摘要： An apparatus which performs solids particles separation from a liquids/solids slurry, and subsequent drying of such solids particles, within a single enclosure. Further processing functions, such as reslurry washing, plug washing, crystal growth and other reactions, can also be carried out within that single enclosure. The single enclosure comprises a partly perforated centrifuge drum which can be rotated about a vertical axis at a fast speed at which the centrifugal effects on material in the drum are substantial so that partly dried solids collect in a substantially cylindrical form on the side wall of the drum, and a slow speed at which the centrifugal effects on material in the drum are negligible; a stripping mechanism which is displaceable within the drum, when the drum is rotated at slow speed, for dislodging solids which have been built up on the side wall of the drum during rotation at high speed; and means for heating at least a bottom part of the drum on which partly dried solids collect when dislodged by the stripping mechanism from the side wall of the drum. The solids can themselves thus be heated, or otherwise processed, to cause evaporation therefrom of any remaining liquid.

摘要： A method and apparatus for heat treating a particulate product including fluidizable as well as non-fluidizable particles. The particles are fed to a first perforated bed plate of a fluidized bed apparatus comprising at least one further stage formed by a second perforated bed plate. Heat treating gas is supplied upwardly to the first and second bed plates to fluidize the fluidizable particles thereon. The non-fluidizable particles are moved from the first bed plate into at least one discharge passage opening in the first bed plate. A flow of classifying gas is directed upwardly through the discharge passage to prevent fluidizable particles from leaving the fluidized bed through the discharge passage, while non-fluidizable particles are allowed to be discharged. The fluidizable particles are transferred from the first stage into the second stage for further treatment.

摘要： The invention relates to the treatment of aqueous materials such as clarified sludge. Disposal of such materials in large quantities is difficult and expensive. The present invention is directed to a treatment method that is economical and results in products which are at least as useful as the starting material. According to the invention, a treatment method comprises mechanical dewatering followed by drying in a fluidized bed drier and burning in a fluidized bed boiler. The heat generated in the boiler is at least sufficient to fulfill the requirements of the drier. The heat generated in the boiler is normally used directly in the drier.

摘要： A process for the continuous drying of chemical products by milling fluidization, in which a fluidized bed of particles of an inert carrier, e.g., quartz sand having a particle diameter of 0.5-1.0 mm., is maintained and the chemical product to be dried is introduced in a wet state, e.g., wet solid or paste or suspension, into the fluidized carrier bed. The chemical product dries on the surface of the inert carrier particles and dry particles of the chemical product leave the relatively large and heavy carrier particles and are carried off in the exit gas. The carrier particles, however, are too large and heavy to leave in the exit gas and so remain in the fluidized bed. If desired, the dried product particles can be further dried, for example by additional drying gas in a cyclone chamber, after which the dried particles are separated from the gas which can be vented and/or recycled.

摘要： A spout-fluid bed drying system and process is comprised of a spout-fluid bed dryer having a conical shaped lower section provided with a packing of heat exchange particles. A cyclone separator is connected to the top of the dryer with separated particles collected by a receiver connected to the leg of the cyclone. A vapor fan compresses the air-vapor mixture before it goes to the heat recuperator and mixing chamber. A tube-shell type heat exchanger, wherein effluent gases from the vapor fan are preheated with heat exchange with the outcoming high temperature gases. A combustion and incineration chamber wherein a natural gas burner is installed at the top and the high temperature flame is used to incinerate the effluent gases introduced from the annulus channel of the chamber to have the odors and VOCs destroyed. A mixing chamber wherein high temperature stream from the incineration chamber is mixed with low temperature stream from the vapor fan to serve as the drying media with the temperature maintained at around 400.degree. C. A slurry discharge nozzle is disposed below the packing and connected to a slurry container via piping and a slurry pump for releasing slurry to the surface of the particles within the packing. Evaporation of water occurs mostly on the surface of particles by contact with hot drying media. A gas-air mixture is fed to the burner through a feed pipe line wherein fresh air is supplied from an air blower.
