High-efficiency rotary type enhanced-drying pyrolyzing furnace

Abstract

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.

Description

technical field [0001] The invention relates to the field of dry pyrolysis of materials containing organic matter, in particular to a high-efficiency rotary enhanced dry pyrolysis furnace. Background technique [0002] The dry pyrolysis furnace is a harmless and environmentally friendly treatment equipment widely used in the fields of biomass, garbage, sludge, waste plastics, etc. The dry pyrolysis furnace can convert these wastes into biomass diesel, carbon black or carbon fixation and other industries raw material. At present, there are many types of drying pyrolysis furnaces, and the structural forms are quite different. According to the movement mode, there are fixed bed type, agitation type, spray type and combined type; according to the structure, there are box type, conveyor type, drum type, and vertical type. , mechanical agitation, rotary, fluidized bed, airflow, vibration, spray and combination, etc. Generally, the appropriate drying pyrolysis furnace will be sele...

AI Technical Summary

Problems solved by technology

The disadvantage of this rotary drying pyrolysis furnace is that the dynamic and static sealing is simple, the air leakage is large, and the heat transfer only depends on a section of the cylinder wall, so the heat transfer area is small, and there is no internal heat transfer enhancement measure. Therefore, the output per unit volume is small, Poor safety, not suitable for industrial drying and pyrolysis, and has great potential safety hazards
