NOVELTY - Biomass carbonization device, comprises hopper (1), conveyor (2) and discharging port. The conveyor folds in a way in the vertical direction set up, one and conveyor exit through a corrugated pipe (3) and imports a next conveyor (2) connected with the inlet of the conveyor covered one layer of electric heating device. The conveyor (2) and corrugated pipe (3) is set with insulating layer, where a heat insulating layer is the whole conveyor (2) connecting upper and lower conveyor and a corrugated pipe (3).    USE - As biomass carbonization device (claimed) e.g. crop straw and forestry waste or derivative a carbide for applying to soil.    ADVANTAGE - The biomass carbonization device solves the problem that the current technology exist of oil gas pipeline blocking, and silicon carbide heating uniformity, temperature gradient is too small or there is no problem of carbide mass difference caused by a gradient, has low energy consumption, no pollution, application of all kinds of biomass.    DETAILED DESCRIPTION - Biomass carbonization device, comprises hopper (1), conveyor (2) and discharging port. The conveyor folds in a way in the vertical direction set up, one and conveyor exit through a corrugated pipe (3) and imports a next conveyor (2) connected with the inlet of the conveyor covered one layer of electric heating device. The conveyor (2) and corrugated pipe (3) is set with insulating layer, where a heat insulating layer is the whole conveyor (2) connecting upper and lower conveyor and a corrugated pipe (3). The electric heating device and the heat insulating layer is a heating space, temperature probe set with the inner corrugated pipe (3), head (5). The temperature probe is connected with a temperature control connecting system. The temperature control system is connected with the electric heating device which is connected, the upper conveyor (2) set with the conveyor (2) which is connected a oil-gas transporting tube. The conveyor each of a gas conveying tube is connected with a jet combustion mechanism set on the heating inner space (4) connecting, discharge hole which is connected with cooling mechanism (7) which is connected. The jet combustion mechanism (4) comprise a fuel supplementary tube (42), air tube (41), oil nozzle and ignition gun, fuel supplying tube (42) passes through the air tube (41) and set with the air tube (41) inner, and the fuel supplying tube (42) is connected with the oil injection nozzle connect, ignition gun set with the air tube (41) of the lower part and is inclined upwards. The oil gas conveying tube is connected with the air tube which is connected. The air tube (41) set with a rotate valve (6). The air tube is connected with the air blower (8) connecting. The fuel supplying tube rotate through valve (6), a booster pump (9) which is connected with the diesel oil storage tank (10) connecting, the booster pump (9) is connected with the pressurizing power source connect. The cooling mechanism (7) comprise a discharge conveyor set and form seal with the discharge conveyor which is tube body on the discharge conveyor seal tube, a seal tube two end, each end is set a one exit, and the refrigerating liquid pipeline of the exit with the refrigeration system which is connected. The oil gas conveying tube is set with a pressure relief cleaning tube. The washing tube is set with a valve. The hopper inlet is connected with the conveyor which is set with a rigid feeding machine (16). The heat preservation layer is cylindrical, where the inner layer is the light heat preservation material, and the outer layer is metal.
