Problems solved by technology

[0002] The biomass production in my country is huge every year, and many kinds of biomass including crop stalks have not been effectively used, and they are just burned on the spot, causing a lot of pollution and wasting a lot of resources
Obtaining oil, gas and carbon resources through rapid pyrolysis is an effective way to utilize biomass resources. However, the current rapid pyrolysis treatment process of biomass mainly includes solid heat carrier and gas heat carrier methods, both of which have the problems of complex process and low product utilization rate.
For example, the literature titled fluidized bed pyrolysis reaction system (refer to Zhu Xifeng's "Principles and Technologies of Biomass Pyrolysis") describes a process flow of a fluidized bed biomass pyrolysis liquefaction device. Complicated, dust removal and condenser pressure are high, and heat carrier preheating has great potential safety hazards

Description

technical field [0001] The invention belongs to the field of biomass pyrolysis, and specifically relates to a regenerative biomass rapid pyrolysis system and method. Background technique [0002] The annual biomass production in our country is huge, and many kinds of biomass including crop straws have not been effectively used, and they are just burned on the spot, causing a lot of pollution and wasting a lot of resources. Obtaining oil, gas and carbon resources through rapid pyrolysis is an effective way to utilize biomass resources. However, the current rapid pyrolysis treatment process of biomass mainly includes solid heat carrier and gas heat carrier methods, both of which have the problems of complex process and low product utilization rate. . For example, the literature titled fluidized bed pyrolysis reaction system (refer to Zhu Xifeng's "Principles and Technologies of Biomass Pyrolysis") describes a process flow of a fluidized bed biomass pyrolysis liquefaction devi...
