Abstract
The invention discloses a drum drying machine employing a circulating fluidized bed straw gasification furnace or a circulating fluidized bed combustion furnace to heat. A motor or an engine on a support frame can drive a drum to rotate on two pairs of idler wheels on the other two support frames through a chain. Chopped straws are fed to a screw straw conveyer through a straw discharging electric rotary valve below a straw storage tank, are conveyed to a fluidized bed of a circulating fluidized bed straw gasification furnace or a circulating fluidized bed combustion furnace by virtue of the screw straw conveyer and are ignited. Wind blown out from a combustion blower passes through a flue gas hot-air device and a plurality of electric control dampers, blows upwards from a plurality of blast nozzles below the fluidized bed of the circulating fluidized bed straw gasification furnace or the circulating fluidized bed combustion furnace, supports combustion of the circulating fluidized bed straw gasification furnace or the circulating fluidized bed combustion furnace and heats the drum. The raw materials are fed to the drum through a raw material conveyer by virtue of a raw material discharging electric rotary valve below a raw material storage tank; the wind blown out from a drying blower enters the drum with liquid in the interlayer to be dried from a raw material conveyer after passing through the hot-air device; a suction ventilator sucks away vapor in the drum through a suction pipe.
