Abstract: China is rich in straw resources, but the phenomenon of burning straw is very severe. It not only wastes resources, but also brings about a series of environmental problem. So this paper designed a kind of upright moving bed of biomass carbonization equipment taking crush biomass granules as material for biomass carbonization, by a innovative route with step-by-step heating and carbonization process. This equipment adopted smoldering and indirect heating method to provide heat for biomass carbonization, and used the screw conveyor, rotary grate and other structures to achieve the continuous carbonization of biomass. This paper introduced in detail the design process of the equipment from the whole to the part, and analyzed its important parameters. At the same time, the paper carried out strength analysis on important structures. In the process of manufacturing and assemblying the equipment, it was found that the trial equipment was designed well, easy to assemble, operate smoothly and the modular design part was easy to install and for later stage maintenance. The paper also conducted a functional test taking rice husk as carbonization raw material. The result showed the grain husk carbonization had good effect, indicating its process route had reasonable design. The equipment had reasonable structure, easy to operate, could sustain continuous production, and had certain market prospect.
