Abstract

The invention discloses a rapid biomass pyrogenation system and method. The system comprises a rapid pyrogenation reactor, a residue cooling machine and a spraying tower. The rapid pyrogenation reactor comprises a reactor body, a multi-layer heat storage type radiation pipe, a biomass inlet, a material distributor, a distribution gas inlet, a plurality of pyrogenation gas outlets and a semicoke outlet. The residue cooling machine is connected with the semicoke outlet and suitable for cooling semicoke. The spraying tower is connected with the pyrogenation gas outlet and suitable for spraying pyrogenation gas through cooling liquid so that bio-oil and fuel gas can be obtained. The system can convert biomass into bio-oil with high value-added, and therefore efficient and clean utilization of biomass is achieved, and the rapid pyrogenation reaction technological process is greatly simplified.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency and clean utilization of biomass in renewable energy, in particular, the invention relates to a system and method for fast pyrolysis of biomass. Background technique [0002] Biomass pyrolysis liquefaction is a process in which biomass is mainly degraded into liquid products and some gas products and solid products after being heated under the condition of complete anoxic or limited oxygen supply. The four most important parameters affecting biomass pyrolysis liquefaction are:10 4 ~10 5 The heating rate of ℃ / s, the reaction temperature of about 500 ℃, the gas phase residence time of no more than 2s and the rapid condensation and collection of bio-oil. Aiming at the conditions of pyrolysis and liquefaction, the reactors of biomass rapid pyrolysis and liquefaction systems developed at home and abroad mainly include: fluidized bed, rotating cone, ablation bed and moving bed, etc., which can...
