Embodiment 2

[0040] The pyrolysis carbonization method of device described in embodiment 1, described method comprises the steps:

[0041] (1) Biomass is continuously fed into the pyrolysis and carbonization chamber 2 through the quantitative feeder 1, and the material is pushed into the dehydration, pyrolysis, and carbonization areas by the pusher blade 13, the stirring blade 14, and the scraper blade 15, and is then pyrolyzed and carbonized. Finally, biochar and mixed gas are produced;

[0042] (2) Biochar and mixed gas produced after carbonization enter the gas-solid separator 4 through the discharge port of the pyrolysis carbonization chamber 2;

[0043] (3) The mixed gas is introduced into the burner by the induced draft fan 7 and burned for the first time, and the tar and wood vinegar in the mixed gas are further decomposed by the action of the ceramic body, and then burned for the second time;

[0044] (4) The high-temperature flue gas produced after combustion enters the outer hea...
