Abstract

A universal industrial modular drying apparatus called a Radiant Plate Dryer for drying sewage sludge, pulp sludge, other industrial sludges, slurries, grains, cereals, organic and inorganic fibres and pulps, chemical waste and other similar materials. The apparatus includes: a dryer module which may be constructed for mobile or fixed installation applications; a constant flow material input system; a number of spiral auger flights in a jacketed open trough joined together to form an upper auger bed; a source of variable infrared energy for providing high intensity infrared flux to open troughs of the upper auger bed;
a condenser to capture and condense volatiles released by the material during processing and to heat glycol for preheating material to be processed for other heat exchange purposes; a number of spiral auger flights enclosed in jacketed tubes formed together to form two other radiant heat augers beds, the jackets being formed in each auger flight by an inner tube containing a spiral auger disposed inside an outer tube defining a jacket divided by flanges into an upper portion through which hot flue gas flows and a lower portion void of flue gas, the radiant heat provided by the inner tube upper portion having vanes extending radially into the jacket affecting heat transfer to the upper inner tube surface thereby focusing high intensity radiant heat in addition to convective heat upon the material enclosed; a temperature control system effective to manage sludge through their "glue" stages; a hot flue gas distribution system to selectively circulate hot flue gases through a auger flight jackets; a flue gas water cooling system using water sourced from the condenser to provide finite process heat control in the auger flights and the dryer module, a condenser vent gas destruction system to consume noncondensable volatiles released during material processing; and a dried material storage system.
