Vibrating fluidised bed

摘要

Vibrating fluidised bed for simultaneous conveying and treatment of bulk material having a gaseous medium, in which the bulk material is conveyed in the longitudinal direction onto a first perforated bottom by means of vibrational drive and the gaseous medium flows from the underside through the perforation of the bottom into the region of the bulk material. In order to improve the energy utilisation, the throughput being increased, a second perforated bottom 2 is provided below the first perforated bottom 1, the gaseous medium of the second bottom 2 flowing in and the gaseous medium being warmed in the space 5 formed by the two bottoms. <IMAGE>
