Tubular type movable bed dry distillation carbide furnace

The utility model relates to a tubular type movable bed dry distillation carbide furnace. Furnace cores are stacked and assembled into a plurality of upright carbide tubes in the matrix arrangement by special-shaped firebricks, and crisscross inner flues 13, the upper and the lower parts of which are communicated, are arranged around the tubes. Materials gradually moves down through gravity in the tubular type movable bed dry distillation carbide furnace, the materials are orderly carried out with a drying, a carbonizing and a cooling stages, and then the utility model quantitatively discharges and feeds the materials in time. The outer wall of the tubular type movable bed dry distillation carbide furnace is provided with an air inlet 23, air can enter the utility model so that pyrolysis combustible materials generated at the moment of carbonization are carried out with partial combustion so as to be favorable to keeping furnace temperature stable and be convenient to calcine charcoal. All furnace gas is led to the lower part of a waste heat boiler 19 through the suction of a chimney 20 and is completely combusted so that the exhaust-heat boiler generates water steam, and meanwhile, the utility model ensures that the exhaust-heat boiler has no yellow and black smoke exhausting phenomenon. The utility model has the advantages of easy construction, convenient operation, stable quality, continuity, energy saving, large yield, no pollution and low labor intensity.
