The invention relates to a high-efficiency rotary type enhanced-drying pyrolyzing furnace. The high-efficiency rotary type enhanced-drying pyrolyzing furnace comprises a drum body 1, a continuous feeding device 2, a continuous discharging device 3, a driving mechanism 4, a rotating gear 5, a supporting round rail 6, a supporting roller 7, a base 8, a sealing connection device 9, a hollow rotary shaft 9.1, a tooth-sealing shell 9.2, a middle cavity 9.3, a pipe cavity 10, an outer drum 11, a cavity body 12, a heat pipe component 13, a pipe (heat pipe) 13.1, fins 13.2, rib plates 13.3, a guide plate 14, a high-temperature cavity inlet 15, a low-temperature cavity outlet 16, a ring-shaped baffle 17, a material inlet 18, a pyrolysis gas outlet 19, a driving gear 20, a driving motor 21 and a solid-residue discharging port 22 and the like. The high-efficiency rotary type enhanced-drying pyrolyzing furnace has the advantages that the defects that the original rotary type drying pyrolyzing furnace realizes heat transfer only by the outer wall of the drum, is small in heat transfer area and can not realize internal heat transfer are overcome, the internal-external simultaneous heat transfer is realized, and an enhanced heat-transfer means is implemented inside, so that unit-volume production capacity of the rotary type drying pyrolyzing furnace is improved multiply; due to adoption of more-reliable and safer sealing connection device, the continuous feeding and continuous discharging of the rotary type drying pyrolyzing furnace can be realized, and safer and cleaner production can be realized; and compared with the original device, the installation and maintenance working is simplified, and the installation and maintenance cost can be saved.
