Pyrolysis reaction furnace and pyrolysis method thereof

Abstract

The invention discloses a pyrolysis reaction furnace and a pyrolysis method thereof. The pyrolysis reaction furnace comprises a pyrolysis furnace body, heating pipes and a screw conveying stirrer; a first feeding hole is formed in the upper part of the pyrolysis furnace body; a middle discharge hole is formed in the lower end of the pyrolysis furnace body; the heating pipes extend into the pyrolysis furnace body to supply pyrolysis heat for a material in the pyrolysis furnace body; the screw conveying stirrer is composed of a shell and a stirring shaft; the shell is arranged at the bottom of the pyrolysis furnace body; a second feeding hole and a final discharge hole are formed in the two ends of the shell in a length direction; the top wall of the shell is provided with a middle feeding hole which is communicated with the middle discharge hole; the middle feeding hole is arranged between the second feeding hole and the final discharge hole; the stirring shaft rotatably extends into the shell to convey the material which is discharged into the shell from the middle feeding hole and the second feeding hole to the final discharge hole. The pyrolysis reaction furnace provided by the invention can lower the energy consumption of a system, increases the yield of pyrolytic tar; meanwhile, the pyrolysis reaction furnace has a simple structure, can reduce occupying area to a certain degree and is liable to industrialization.

Description

technical field [0001] The invention relates to the technical field of high-temperature air combustion, in particular to a pyrolysis reaction furnace and a pyrolysis method thereof. Background technique [0002] The system energy consumption of the pyrolysis reaction furnace of the related art is high, and the solid product itself after pyrolysis of the material in the pyrolysis reaction furnace has high sensible heat, while the pyrolysis process and the pyrolysis reaction furnace of the related art greatly waste the solid product Sensible heat, resulting in energy loss. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a pyrolysis reaction furnace, which can reduce the energy consumption of the system and increase the yield of pyrolysis tar. Simultaneously, the structure is simple, the occupied area can be reduced to a certain extent, and indu...
