Abstract

The invention relates to a device used in a biomass pyrolysis liquefaction reaction process, in particular to a solid heat carrier heating device for biomass pyrolysis, which includes a fluidized bed burner and a heat carrier heater connected by pipelines, The fluidized bed burner includes a burner body, the burner body is connected to a biomass powder fuel feeder, and the heat carrier heater includes a heat carrier heating furnace, and the upper and lower ends of the heat carrier heating furnace are respectively connected to heat The carrier feeder and stocker, the heat carrier heating furnace is provided with a smoke inlet, and the flue gas purification chamber is connected to the smoke inlet through a smoke inlet pipe, and the smoke inlet pipe extends into the bottom of the heat carrier heating furnace. The high-temperature flue gas of the invention flows upward from the bottom, and performs forced convection heat exchange with the falling solid heat carrier in the heat carrier heating furnace, and has high heating efficiency.

Description

technical field [0001] The invention relates to a device used in a biomass pyrolysis liquefaction reaction process, in particular to a solid heat carrier heating device for biomass pyrolysis. Background technique [0002] Biomass materials have the characteristics of environmental friendliness and renewable resources. They are one of the ideal clean energy sources and have broad prospects for development and utilization. Biomass pyrolysis and liquefaction technology is a thermochemical method. It uses high-temperature solid medium to heat powdery biomass to achieve rapid pyrolysis and liquefaction of biomass. It is one of the processes for producing bio-oil. It has the advantages of small cooling load and easy recovery of waste heat from the carrier. , is also one of the most potential biomass energy utilization technologies. [0003] Among them, heat carrier heating powdery biomass is a key link in the production process of bio-fuel, and the advanced technology of heat car...
