Biomass carbonizing device
2014
The utility model discloses a biomass carbonizing device. The device comprises a drying chamber, a carbonization furnace, a tar removing device, a heat exchanger and a combustion furnace, wherein biomass materials and heat source gas make direct contact to achieve heat exchange in the drying chamber and the carbonization furnace, so that biomass materials are quickly dried and carbonized; meanwhile, a pyrolysis gas tar recovery device is arranged, and thermal energy can be fully and efficiently utilized through reasonable design. Compared with the prior art, the device has the advantages that energy utilization rate is high, and heat released by fuel burning is used for biomass carbonization to the maximum; biomass is evenly heated, pyrolysis gas serves as the heating medium to directly heat biomass materials, high-temperature pyrolysis gas makes direct contact with biomass materials, contact area is large, full contact is achieved, and heat transfer is conducted more directly; continuous work can be achieved, and production efficiency is high; carbonization temperature is easy to control.
