Biomass Fast Pyrolysis Liquefaction Control System Design Based On SOPC

Biomass as a renewable energy, is a hotspot in the field of energy research. How toget to the biomass fast pyrolysis liquefaction development of high energy density from alow energy density, become a focus on the research of renewable energy. Controlsystem of biomass fast pyrolysis technology is the key to the development, however, thebiomass fast pyrolysis of international studies various types are still in the experimentalcondition, the control system is simple, automatic control level is very low, the generaleffect. Study on control system of fast pyrolysis of biomass is a realistic problem topromote research and development pace of upgrading.The biomass fast pyrolysis liquefaction control system based on SOPC mode, notonly convenient design, and has the advantages of low cost and short period of. Thetechnology of fluidized bed process model pattern evaluation of higher at present,combined with the SOPC construction of biomass fast pyrolysis liquefaction controlsystem. Summarize the biomass fast pyrolysis liquefaction control system with highperformance by experiment.This design uses ALTERA’s SOPC development tools Quartus II10.1to design,using SOPC Builder to design a personalized NiosII soft-core (processor, memory, IOinterface and peripheral modules are connected together to form a complete system),optimization of cutting peripherals to save system resources, add the required interfaces.Functions module using the Verilog HDL hardware description language. To completethe SOPC system hardware is developed by using Quartus II software, the compilerenvironment NiosII system software program, to generate the output logical file,program header files and library files. The software design of the system is carried outin the NiosII development environment, based on software SOPC Builder generated, thesource program written, compiled, linked to generate executable file, download systemto GX-SOPC-EP2C35-CIDE integrated development platform, the executable programdebugging. Finally, loaded into the fluidized bed biomass fast pyrolysis equipmentinstallation, debugging of hardware and software system, using different sizes of pinewood particles as raw material testing, test results analysis and summary of temperature and residence time on fast pyrolysis of pine particle heat liquefaction liquefaction ofsolution, the oil yield is76.5%(at the temperature of480℃, the residence time of4seconds, pine particle size0.2mm), the results are close to the theoretical value. Toverify the application functions and the flexibility of the SOPC embedded system.
