Embodiment approach
[0023] see figure 1 , implementing a biomass moving bed pyrolysis fluidized bed gasification composite reaction device according to the present invention, comprising a moving bed pyrolysis reaction section and a fluidized bed gasification reaction section. The raw material enters the moving bed pyrolysis reaction section 3 propelled by the screw from the material inlet 1. The biomass is dehydrated and dried by heating, and the volatile matter is desorbed by pyrolysis. After the pyrolysis is completed, under the action of the screw propeller I4, the pyrolysis reaction section from the moving bed Section 3 enters the fluidized bed gasification reaction section 6 through the connecting channel 5, and enters the fluidized bed gasification reaction section 6 with the lower gasification agent input pipe 8, and then enters the ascending gasification reaction section 7 through the gasification agent distributor 7. The agent undergoes a gasification reaction. The remaining gasificatio...

Description
technical field [0001] The invention relates to a biomass pyrolysis and biomass gasification composite reaction device, in particular to a biomass gasification device for simultaneously realizing biomass pyrolysis and biomass gasification to produce combustible gas fuel. Background technique [0002] The main technical method for generating biomass energy from biomass is biomass gasification reaction. Biomass gasification is a process in which oxygen or oxygen-containing substances are used as gasification agents to generate combustible gases from carbon oxides in solid biomass. In this process, it is also accompanied by the reaction of carbon and water vapor and the reaction of carbon and hydrogen. [0003] The basic reactions in the biomass gasification process include drying of raw materials (100-150°C), thermal decomposition reactions (>160°C), reduction reactions (carbon dioxide reduction reactions, water vapor reduction reactions, methane generation reactions and ca...
