Fluidized bed drying technology

Circulating fluidized bed drying technology is to add the material to be dried into the fluidized bed through a feeder (note: a bed has been added to the fluidized bed Material), preheated air or various boiler exhaust gases are introduced from the bottom of the equipment container, so that the material particles in the fluidized bed are blown up, suspended and pulverized in a boiling state. At the same time, the dried materials are collected at the upper outlet of the fluidized bed.

This technology has been used in engineering applications such as sludge drying. The Institute of Thermal Energy of Southeast University applied for a patent to dry domestic sludge and industrial sludge respectively. It can dry sludge with a moisture content of 85 It is 0.5~1mm solid particles with a moisture content of 0~5. And it has been applied to actual engineering, with a daily processing capacity of 50 tons. The main influencing factors are temperature, feeding speed and air inlet flow.
