Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] In this embodiment, the device shown in Figure 1 is used, and the reaction furnace includes an upper pyrolysis furnace [4], a lower gasification furnace [6] and an inner annular catalyst bed [5] in the middle. A screw feeding device is arranged on the upper part of the pyrolysis furnace [4], and the screw feeding device includes a biomass bin [1], a screw feeder [2] and a feeding pipe [3] of the feeder, and the lower feeding pipe [3]. The feed pipe [3] is inserted into the upper section of the pyrolysis furnace [4] of the pyrolysis gasification device. The lower part of the biomass pyrolysis furnace [4] is connected to the lower gasification furnace [6]. A conical gas diffusion zone [8] is set at the bottom of the gasification furnace [6]. There is a porous ceramic air distribution plate [5] in the middle of the area [8], the bottom of ...
