摘要：NOVELTY - The utility model claims a biomass fluidized bed spiral-flow gasification device, the device comprises a cylindrical gasification furnace body, a feeding system, an air inlet system, a cyclone separator, a material returning device and a hot gas outlet; said feeding system is composed of a hopper, a feeder and a spiral feeder, air inlet system comprises a centrifugal fan and a blast nozzle and gas spray gun connected with it; the bottom of the cyclone separator is provided with one end of returning, returning to the bottom of the gasification furnace; Wherein, spiral feeder and gas spray gun is installed on the side wall of the gasification furnace, a nozzle mounted on the bottom of the gasification furnace. spraying high velocity gas in the furnace through the gas lance on the furnace wall and the bottom of the gasification furnace the injected gas forming rotational flow pushes the biomass raw material spiral upward motion and carrying out gasification reaction and increases the reaction residence time and biomass and gasification medium transverse mixing degree, improves the heat efficiency of conversion of biomass and a gasification furnace.
