Abstract
Dispositivo para secar sólidos muy húmedos. El dispositivo es una combinación de lecho fluidizado y lecho móvil. El fondo del lecho móvil está inclinado para recoger el agua que escurra del sólido. El agente desecante es aire u otra mezcla gaseosa caliente que se alimenta por la parte inferior del lecho fluidizado y pasa después a través del lecho móvil. El sólido se alimenta a la entrada del lecho móvil y circula por efecto de la gravedad. En el lecho móvil el sólido sufre un secado parcial progresivo y se capturan los sólidos arrastrados desde el lecho fluidizado, en el cual se produce el secado final. El dispositivo va dotado de sistemas de control automático de caudales de gas, líquido y sólido, niveles de lechos, temperatura, humedad de salida del sólido y presión total interior. Tiene aplicación en la industria de secado de sólidos granulares.Device for drying very wet solids. The device is a combination of fluidized bed and mobile bed. The bottom of the moving bed is inclined to collect the water that drains from the solid. The desiccant is air or another hot gaseous mixture that is fed from the bottom of the fluidized bed and then passes through the moving bed. The solid is fed to the entrance of the moving bed and circulates due to gravity. In the mobile bed the solid undergoes a partial progressive drying and the entrained solids are captured from the fluidized bed, in which the final drying takes place. The device is equipped with automatic control systems for gas, liquid and solid flow rates, bed levels, temperature, solid output moisture and total internal pressure. It has application in the drying industry of granular solids.
