Abstract
In order to solve the problems of the existing biomass pyrolysis and carbonization equipment, such as energy consumption caused by external heat source heating and the complexity of carbonization device, a new type of rotary continuous carbonization equipment was designed. Through simulation analysis and experimental research, the optimal speed range of the designed carbonization furnace was obtained, and the carbonization experiment was carried out with biomass corn straw as raw material. The experimental results show that the equipment can process 2.13 tons of biomass per hour, and the yield of biochar is 30.2%. The performance of the equipment has reached the expected target, and the continuous and efficient carbonization of biomass has been realized.
