Circulating fluidized bed drying technology is the material to be dried by the feeder adding Fluid Bed Dryer (Note: the fluidized drying material has been added to the bed), passes into the preheated air or various boiler exhaust gas from the equipment under the container, the particles in the fluidized bed is blown in boiling state of suspended crushing. At the same time, dry material is collected at the upper outlet of the fluidized bed.
The technology has been applied to the engineering application of sludge drying, Southeast University energy patent of sewage sludge and industrial sludge drying, the moisture content is 85% of the sludge drying for moisture content of solid particles of 0~5% 0.5~1mm. And it has been applied to the actual project, the daily handling capacity of 50 tons. The main influencing factors are temperature, feed rate and inlet air flow.
