Internal combustion type heating rotating cone type biomass pyrolysis liquefaction device

Abstract

The invention relates to an internal combustion type heating rotating cone type biomass pyrolysis liquefaction device. The device is characterized in that two concentric cones are arranged in a reactor, the outer cone is a rotating cone, and the inner cone is a fixed cone; a charging barrel is sectionally arranged into an upper section charging barrel and a lower section charging barrel, the upper part of the rotating cone is connected with the lower section charging barrel, and the upper section charging barrel is communicated with a spiral feeding mechanism; the upper part of the fixed coneis communicated with a flue gas pipeline; the end surface at the bottom part of the fixed cone is closed, and the lower part of the fixed cone is tangentially connected with a burning pipeline; a porous filter tube is arranged in the reactor, a reactor is led out form the other end of the porous filter tube, and the reactor is communicated with a cyclone dust collector positioned outside the reactor, the output end of the bottom part of the cyclone dust collector is connected with a carbon collecting box, and a gas outlet opening at the top part is connected with a condenser through a pyrolysis gas pipeline; an oil outlet opening on the condenser is communicated with an oil collecting tank, the air outlet opening of the condenser is accessed into a pyrolysis gas burner through a pyrolysisgas return pipeline. The invention realizes biomass self-heating type pyrolysis liquefaction, effectively improves the utilization ratio of the pyrolysis byproduct and reduces the total cost for biomass liquefaction.

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 mainly includes forestry materials, agricultural waste, municipal waste and livestock and poultry manure. 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 low S and N content can greatly reduce the greenhouse effect and environmental pollution. Biomass pyrolysis liquefaction refers to the direct pyrolysis of biomass under the conditions of medium temperature, high heating rate and extremely short gas residence time in the absence of oxygen, and the product is rapidly cooled to obtain high-yield liquid fuel. That is bio-oil.

[0003] At present, the focus of research on biomass pyrolysis liquefaction equipment is how to better achieve efficient heat transfer and self-heating pyroly...
