Industrial production apparatus for high-power microwave pyrolysis of biomass

Abstract

The invention relates to an industrial production apparatus for high-power microwave pyrolysis of biomass. The industrial production apparatus comprises a material conveying system, a microwave pyrolysis system, a pyrolysis flue gas separation and collection system, a suction and discharge system and a biomass fuel gas utilization system, wherein a microwave reflection diffusion chamber completelycovers a large-capacity microwave oven cavity, the microwave power density is increased by multiple microwave sources, adjacent and opposite microwave waveguides are arranged in a staggered manner, and the phase angle of input microwave is controlled by PLC, such that the sealing and the heat insulation of the furnace cavity are ensured, the microwave radiation leakage is shielded, and the industrial production and safe operation for continuous and efficient high-power microwave pyrolysis of biomass is achieved. Compared to the existing biomass pyrolysis device, the industrial production apparatus of the present invention has the following characteristics that the time is shortened by 55-90%, the energy consumption is reduced by 50-80%, the solid, liquid and gas products produced by the biomass pyrolysis are completely collected and utilized, no waste is discharged, the clean production is achieved, and the reliable equipment and the control method are provided for the comprehensive industrial application of biomass resources.

Description

technical field [0001] The invention relates to an industrial production device for pyrolyzing biomass with high-power microwaves. technical background [0002] At present, the industrial production devices that are widely used and can continuously pyrolyze biomass are mainly fixed bed, fluidized bed, entrained flow, multi-furnace device, rotary furnace, rotating cone reactor, spiral pyrolysis reactor, etc., such devices Burning biomass or heating biomass through heat conduction from the outside to the inside results in a large loss of heat energy; the pretreatment of biomass raw materials consumes a lot of energy and costs; the system is complex, the equipment is huge, and the production environment is harsh; only biomass can be processed Gasification or liquefaction, single product, poor quality and subsequent utilization rate; the effective utilization rate of biomass resources is greatly reduced, the economic benefits are also reduced, and a large amount of residue is di...
