Pyrolysis furnace device for mesophilic fast pyrolysis of biomass

Abstract

The invention relates to a pyrolysis furnace device for the mesophilic fast pyrolysis of biomass, and relates to the technical field of thermochemical equipment of biomass. The pyrolysis furnace device comprises a pyrolysis furnace shell provided with a raw material inlet, a pyrolysis gas outlet and a solid carbon outlet; the pyrolysis furnace is arranged horizontally, a stirring shaft is connected to the lateral lower side of the center of a circle of the fixed shell of the pyrolysis furnace through a sealing device and a bearing to form the eccentric arrangement of the stirring shaft in the pyrolysis furnace, so that the upper part in the pyrolysis furnace is provided with a space for direct combustion and heat supply; the stirring shaft is fixedly provided with a plurality of stirring rods which are arranged at different angles in a staggered mode along an axial direction, so that the bearing stress of the stirring shaft during material stirring is uniform, and the maximum distortion stress of the stirring shaft is reduced; and each stirring rod is fixedly provided with a stirring claw forming a certain inclined angle with the stirring rod, and the stirring claws not only enable materials to perform circumferential motion in the pyrolysis furnace, but also enable the materials to perform axial motion towards the outlet direction of the pyrolysis furnace so as to perform pyrolysis and convey on the materials. The pyrolysis furnace device is suitable for the mesophilic fast pyrolysis of the biomass, and has high efficiency, low cost and safe and stable operation.

Description
