The invention provides a biomass green carbonization poly-generation device and method. The device comprises a fluidized bed two-stage carbonization furnace for producing high-quality biochar / activated carbon, a multi-stage cyclone separation device for realizing coarse and fine separation of carbon particles, a two-stage direct-current guide vane type separation device for realizing three-phase separation of retorting gas, and mixing the retorting gas into a gas-fired boiler for clean combustion, green emission is achieved, and the boiler recovers heat of retorting gas to generate steam which is supplied to process steam. According to the invention, steam is generated through biomass carbonization poly-generation of biochar, activated carbon, carbon black, carbon-based fertilizer, wood tar, wood vinegar and waste heat. Poly-generation is achieved through multiple technical means such as flow adjustment, stepped utilization is conducted on biomass, and economic value maximization is achieved. Solid and liquid wastes are avoided, zero emission is realized, and green utilization of resources is realized.
Description
technical field [0001] The invention relates to the technical field of biomass carbonization and the technical field of biomass activated carbon, in particular to a kind of biomass carbonization applied to biomass charcoal, activated carbon green polygeneration and its method. Background technique [0002] Biomass is a precious green and low-pollution renewable resource on the earth. Our country is very rich in biomass energy resources. Firewood forests, forest harvesting residues (branches, roots), wood processing residues (sawdust, bark, slabs), construction In many places, waste wood and wooden packing boxes are crushed and sent to power plants for direct power generation. The production capacity is single and the efficiency is low. The invention converts these high-quality resources into biomass charcoal, activated carbon, carbon black, charcoal-based fertilizer, wood tar and wood vinegar. Develop the secondary resource utilization of biomass carbonization, improve the ...
