Modeling And Simulation Of Rotating Cone Flash Prolysis Reactor For Biomass

With the development of the science and technology , the project technology has already developped from the designs of the two-dimensional CAD to the three dimensional dynamic structural design,At the end of 1950's, simulation has been employed into the manufacture system. Simulation has made a great progress in the 1980's. Technology of virtual prototype can forecast product performance in the design stage of product, optimize design of product, reduce cycle of the research and manufacture of product and save the expense. The researcher makes the modeling of actual manufacture environment, and can test, compare, monitor and evaluate some plans of the manufacture system by means of simulation method, thus can change and choose manufacture strategy.Under the support of national 863 project item "the new technology by integrated biomass repeated flash prolysis and liquefaction to product bio-oil (2001AA514060)", the dissertation author research modeling and simulation of rotating cone flash prolysis reactor for biomass. Domestic and foreign research for rotating cone has got some achievements. The dissertationadopted a new research method, with advanced software of dynamics simulation------ADAMS software, established the model of rotating cone and heat carrier, so the development and research to the machine parts was allowed to conduct. The dissertation author carries on mechanics analysis of the heat carrier, confirms force of exerting on heat carrier, then chooses correct restraint and carries on dynamics simulation. The helix rotary motion orbit of heat carrier in high speed rotating cone can be observed. The allocated proportion relations between solid residence time and speed of rotating cone can be obtained. The dissertation author changes angle of rotating cone and speed of rotating cone, and the allocated proportion relations among angle of rotating cone, speed of rotating cone and solid residence time can be obtained. The dissertation author chooses the correct restraint, confirms the reasonable objective function, and carries on the optimized analysis, thus the best allocated proportions relations among angle of rotating cone, speed of rotating cone and solid residence time can be obtained, thus the best parameter can be determined, so the request of design can be achieved.The dissertation thesis author research modeling and simulation of rotating cone flash prolysis reactor for biomass, which will offer a new method and technology basis for our country on research of rotating cone flash prolysis reactor for biomass, which will also provide the important reference for the analyzing and designing the same unit.
