Abstract
The invention discloses a device for drying lignite by microwave fluidization. The device comprises a microwave heating chamber and a fluidized bed, wherein the fluidized bed is arranged at the bottom of the microwave heating chamber and communicated with the microwave heating chamber; the microwave heating chamber comprises a metal furnace shell capable of shielding microwaves, a material inlet and a smoke gas exhaust port are arranged at the top of the furnace shell, at least one microwave generation device is arranged on the side surface of the furnace shell, a cylindrical ceramic furnace tube through which microwaves can penetrate is further arranged in the furnace shell, a plurality of layers of annular metal baffle plates are arranged along the inner wall of the ceramic furnace tubefrom top to bottom, a rotating shaft is arranged at the center of the ceramic furnace tube, a plurality of rake-shaped structural members which correspond to the metal baffle plates respectively are fixedly arranged on the rotating shaft along the axial direction, and a tapered material guide disc is fixedly arranged on each rake-shaped structural member; and the fluidized bed is in vertical structure, an air chamber of the fluidized bed is connected with a hot air furnace through a first hot air inlet pipe and an overflow pipe connected with a finished product warehouse is arranged at the upper part of the fluidized bed. By adopting the device, the large-scale, fast, low-energy-consumption and deep-drying production of the lignite can be realized.
