[0039] The biomass raw material enters the spherical carbonization furnace 4 through the feed pipe 14, and the spherical carbonization furnace 4 provides a reaction space for the pyrolysis, carbonization and gasification of the biomass. It is worth noting that when feeding, the opening direction of the arc filter seat 1602 of the flip seat 16 is ensured to be upward, and Figure 1 On the contrary, at this time, the material falls into the arc filter seat 1602, and the spherical heater 3 heats the spherical carbonization furnace 4 to provide the required temperature conditions for the pyrolysis and carbonization of the biomass.

[0040] Start the servo motor 5, and the output shaft of the servo motor 5 drives the connecting frame 2 to swing.
