Reaction apparatus of microwave pyrolysis biomass

Abstract

The invention discloses a reaction apparatus of a microwave pyrolysis biomass. The reaction apparatus comprises a microwave pyrolysis unit, the microwave pyrolysis unit comprises a microwave thermal decomposition furnace, and at least a feed inlet arranged outside the microwave thermal decomposition furnace, the microwave thermal decomposition furnace comprises a solid-phase pyrolysis part and a gas-phase pyrolysis part connected in order from down to up, the solid-phase pyrolysis part comprises a solid-phase hollow circular column composed of metal mesh, and the solid-phase hollow circular column is filled with a solid-phase microwave absorbent and a catalyst. The reaction apparatus increases the pyrolysis heating rate, reduces the generation amount of solid carbon residue, increases theproportion of pyrolysis gas in products, and optimizes the pyrolysis reaction process, has the advantages of simple equipment, less land occupation, and convenient operation, can complete operation ofcontinuous feeding and deslagging, and is convenient for operation and management.

Description

technical field [0001] The invention relates to a biomass pyrolysis device, in particular to a microwave pyrolysis biomass gasification polygeneration reaction device. Background technique [0002] Biomass is the energy stored in the biomass carrier in the form of solar energy in the form of chemical energy. It is an important renewable energy source and the only renewable carbon source. With the development of the world economy, the supply and demand situation of fossil fuels such as coal and oil is severe, and it is inevitable that clean and renewable energy will replace fossil fuels. Since the production, conversion and utilization of biomass constitute a closed cycle of carbon, its carbon neutrality is conducive to slowing down global warming; in addition, biomass has the advantages of less polluting substances, relatively clean combustion, and low cost. [0003] As the largest agricultural country in the world, my country has abundant biomass resources. Theoretical bi...
