Problems solved by technology

This method can avoid the impact of flue gas on pyrolysis products, but the heat transfer for biomass pyrolysis is limited
[0008] Therefore, when the above three pyrolysis liquefaction reactors use the above four methods to realize the self-heating pyrolysis liquefaction process, the shortcomings of the reactor and the method itself are unavoidable.

Abstract

The invention discloses an internal combustion heating movable-bed biomass-pyrolysis liquefaction device which includes a reactor (7); the inside of the reactor is provided with an internal combustion pipeline (5); both the inlet and the outlet of the internal combustion pipeline (5) are arranged outside the reactor (7); a hopper (1) is arranged above the reactor (7); a blanking control valve (2)is arranged on the hopper (1); a rotary shaft (6) is arranged in the center of the reactor (7); conical hoppers (4) are arranged on the rotary shaft (6); conical material dividing umbrellas are arranged between the conical hoppers (4); the material inlet of the hopper (1) is arranged above the conical hoppers (4); a pyrolysis gas outlet (20) is arranged on the reactor (7); the bottom part of the reactor (7) is provided with a slag discharge opening (14); a cyclone separator (23) is connected on the gas pipeline of the pyrolysis gas outlet (20); the flue gas outlet of the cyclone separator (23) is connected into a condenser (26); an oil outlet and an outlet for non-condensable gas are arranged on the condenser (26); the outlet for non-condensable gas is connected to a gas buffer tank (28) through a draught fan. The biomass-pyrolysis liquefaction device reduces the liquefaction cost of bio-oil, has a simple structure and a low processing and manufacture cost as well as is simply and conveniently operated, managed and maintained.

Description

technical field [0001] The invention relates to a pyrolysis liquefaction device, more specifically a pyrolysis liquefaction device using biomass as raw material. Background technique [0002] Biomass is a kind of renewable energy with abundant reserves, which can be used as an alternative energy source to achieve CO 2 Zero emission, and the low content of S and N in it can greatly reduce the greenhouse effect and environmental pollution. [0003] At present, the design and research focus of biomass pyrolysis liquefaction equipment is how to better achieve efficient heat transfer and self-heating pyrolysis liquefaction of biomass particles. [0004] For now, the pyrolysis technology based on bubbling fluidized bed, circulating fluidized bed and rotating cone reactor is relatively successful. achieves efficient heat transfer, but works on a completely different principle. [0005] In the fluidized bed reactor, the biomass particles and the heat carrier mainly rely on the dr...
