Fluidized bed drying technology of fluidized bed dryer

circulating fluidized bed drying technology is to add the material to be dried into the fluidized bed body through a feeder (note: bed material has been added in the fluidized bed), and introduce preheated air or various boiler exhaust gases from below the equipment container, so that the material particles in the fluidized bed are blown up and suspended and crushed in a boiling state.

at the same time, collect the dried materials at the outlet of the upper part of the fluidized bed.

This technology has been applied to the engineering application of sludge drying. The Thermal Energy Institute of Southeast University applied for a patent to dry domestic sludge and industrial sludge respectively, which can dry sludge with water content of 85% into .5~1mm solid particles with water content of ~5%.

and it has been applied to engineering practice, with a daily processing capacity of 5 tons.

The main influencing factors are temperature, feeding speed and air intake.
