Spout Fluid Bed Dryer

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 drying system for drying organic refuse material having fertilizing properties, said system comprising a spout fluid bed dryer housing having a conical section provided in at least a part thereof with a packing of heat exchange particles, means to feed a fine spray of an organic refuse material slurry to said packing, inlet means at a narrowed end of said conical section to admit a hot drying gas stream into said housing to heat said packing and to dry said slurry to produce dried slurry particles, said dried slurry particles being convected to a separation means where said dried slurry particles are separated, said effluent gases being fed to a combustion chamber for destroying volatile organic compounds and odor gases from said effluent gases before releasing a regulated amount of the treated gases which is now clean gases and for further heating and drying said gas stream to feed said inlet means of said dryer housing.

levels than previously achieved by the above referred-to drying processes and wherein the treatment capacity can be increased and further wherein the effluent gas is incinerated in a combustion chamber which also provides the hot air for the drying chamber.

It is therefore a feature of the present invention to provide a spout fluid bed dryer and a recuperative type combustion chamber which provide the above need.

Another feature of the present invention is to provide an organic refuse material drying system employing a spout fluid bed dryer wherein the slurry solution is sprayed from either the top, the bottom or the side walls into the bed material by atomizing nozzles, although other atomizing devices are also workable, to promote intimate contact between liquid drops, solids particles and drying gases.
