The invention belongs to the field of
biomass energy utilization, and relates to a
grinding belt-type device for rapid
catalytic pyrolysis of
biomass and a method. The device comprises a hopper, a feed
system, a
grinding belt-type
pyrolysis reactor, a gas-
solid separation system, a
pyrolysis gas condensation
system, a
combustion system, a bio-oil collection tank, a
charcoal collection tank, an airpreheating system and a
flue gas purification system, wherein the
grinding belt-type
pyrolysis reactor comprises grinding belts, heating tubes, driving drums, tensioning devices, a sealed casing, a feed inlet, a
discharge opening and a gas outlet. Pretreated material particles are continuously sheared and rubbed by the grinding belts with speed difference on two sides, and are heated by the multi-layer heating tubes to continuously pyrolyze on the surface while stripping the residual
charcoal, so that a catalyst and heat can be fully fed inside the particles; the pyrolysis gas is rapidly condensed by gas-
solid separation to obtain high-grade bio-oil fuel or bio-oil rich in specific high value-added products;
combustible gas and
coke produced by
combustion generate high-temperature
flue gas for heating the heating tubes, so as to achieve an autothermal pyrolysis process.
