Abstract

The invention relates to the technical field of biomass energy conversion and utilization, in particular to a segmented spiral stirring biomass pyrolysis liquefaction system, including a first biomass powder feeding system, a segmented spiral stirring reactor, a gear system, a carbon Collector, heating system, condensing system, array type hot flue gas pipeline, cylinder heat transfer device, wherein the segmented spiral stirring reactor includes the reactor body and segmented spiral stirring device, and the segmented spiral stirring device includes the stirring shaft , spiral blades and retention blades. The segmented spiral stirring device in the reactor of the present invention can increase the disturbance of the biomass powder in the reactor, make the heating time longer, the heating surface wider, improve the pyrolysis efficiency, save energy consumption, and at the same time, the array type The hot flue gas pipeline realizes multi-point heating, ensures the sufficient supply of heat, avoids the reduction of heat transfer efficiency caused by heat loss, and improves the heating effect.

Description

technical field [0001] The invention relates to the technical field of biomass energy conversion and utilization, in particular to a segmented spiral stirring biomass pyrolysis liquefaction system. Background technique [0002] With the exploitation and utilization of fossil energy, the reserves of fossil energy have declined rapidly, and many environmental problems have been caused. Therefore, the development of a new renewable energy source is of great significance to the improvement of the environment and the progress of human society. Biomass energy is energy stored in animals, plants, and microorganisms, which can be converted into conventional solid, liquid, and gaseous fuels. It is a renewable energy source and the only renewable carbon source. Biomass pyrolysis technology is a cutting-edge technology for high-value utilization of biomass resources, which can convert biomass raw materials into high-calorific value, high-grade liquid fuel bio-oil, and improve the comp...
