DETAILED DESCRIPTION - Continuous two-stage nitrogen-enriched biomass pyrolysis reaction device, comprises sequentially connected a preheat auger pyrolysis reactor (1) and rotary spoiler pyrolysis reactor (8) to achieve the two pyrolysis reactions, respectively, where the preheat auger pyrolysis reactor comprises a barrel-shaped preheat decomposition reaction tube (20) that is provided in the auger and disposed in the barrel-shaped preheat decomposition reaction tube at one end of the feed tube (2), where the reaction solution preheat cylinder on the cylinder is also opened a pass into the exogenous nitrogen for powdered exogenous nitrogen inlet tube (4) and pyrolysis gas outlet tube. The biomass is fed through the feed tube into the reaction solution preheat cylinder and the auger is driven through the use of exogenous nitrogen powder preheated solution and the solution from the reaction tube to warm up the other end of the discharge port output, and thermal pyrolysis from the pyrolysis gas output vent pipe. The rotary spoiler pyrolysis reactor comprises a rotatable cylinder-shaped pyrolysis reaction tube. The tubular pyrolysis reactor and relative rotation of the inner rotor of the spoiler are provided or disposed at one end of the exogenous nitrogen gas inlet tube and high-temperature anaerobic inlet tube heat load. The pyrolysis reactor tube on one end of the decomposition reaction of the preheating drum includes a discharge opening through preheating solution feed line, and preheating solutions biomass feedstock is conveyed through the preheating tube and entered the pyrolysis reactor tube. The anaerobic and high temperature hot gas inlet tube carrier is present in the gaseous nitrogen inlet tube. The exogenous gaseous nitrogen and high temperature heat carrier introduce anaerobic atmosphere using the spoiler rotor and pyrolysis reactions cylinder of relative rotation. The high temperatures can heat and preheat the solution of oxygen contained in the biomass feedstock intense heat and preheat the solution, so that the reaction solution of raw material feedstock with nitrogen gas generates sufficient heat to achieve a two-stage pyrolysis multiphase product.
