| Fluidized bed biomass fast pyrolysis technology is a highly efficient chemical conversion method which can transform the low-grade biomass into high quality bio-fuel or high value-added chemical products. Based on the summary of the existing domestic and international research on biomass fast pyrolysis technologies, this study not only propose the optimization of pyrolysis process, the design of key equipment, the planning of equipment installation and commissioning process in a pilot’s point of view, but also provide a theoretical basis for our industrial technology development of biomass fast pyrolysis and the design and optimization of the device amplified.Developed a set of annual processing capacity of1,000tons of BL-SCFB-6-type fluidized bed biomass fast pyrolysis equipment, and reasonable optimize the pyrolysis process. Design a handling capacity of150kg/h screw feeder and integrate key components of the airlock, the cooling water jacket, seal component, and solve anti-spray, high temperature of feed tube, the shaft end sealing and other issues. Through cold state experiment, comprehend the feeding state of the screw feeder, as well as the influence of the speed and pressure. Design segmented fluidized bed reactor and to optimize the design of air distribution plate; Design sieve-condensing tower, checking through fluid dynamics; According to the design requirements of the equipment installation and commissioning programs, drawn equipment layout plan and describe the operating procedures Preliminary include equipment installation, pressure test leak detection, monomer debugging, linkage commissioning and put to trial. |
