Abstract
The invention discloses a poly-generation system using biomass and solar energy for making methyl alcohol and generating power. The poly-generation system comprises a solar energy heat collecting reaction subsystem, a biomass gasification subsystem, a methyl alcohol synthesis subsystem and a power generation subsystem. Main devices comprise a flat plate type solar energy drying device, a groove type solar thermal collector, a steam generator, a tower type solar energy reflection mirror field, a tower type high-temperature gasification reactor, a gas temperature reduction device, a gas condensation purifying device, a compressor set, a methyl alcohol synthesis tower, a heat exchanger, a gas-liquid temperature reduction device, a flash tank, a separator, a mixer, rectifying tower, a methyl alcohol, a combustion chamber, a compressor, a gas turbine, a waste heat boiler, a steam turbine, a condenser, a water feed pump and a power generator. By the utilization of the poly-generation system, solar energy is converted into chemical energy, the problems that the storage of solar energy is difficult, and stability of renewable energy source delivering is poor are solved, and meanwhile the effective utilization efficiency of the biomass is improved.
Description
technical field [0001] The invention relates to the technical field of complementary utilization of multiple renewable energy sources, in particular to a polygeneration system for producing methanol and generating electricity by using biomass and solar energy. Background technique [0002] In the context of rapid economic development, human demand for energy is increasing, and fossil fuels such as coal, oil, and natural gas are consumed in large quantities, which will not only bring about a sharp decrease in energy resource reserves, but also cause serious environmental problems. pollution, especially large amounts of CO 2 Greenhouse gas emissions will affect the global ecological balance. [0003] China's total primary energy production increased from 1.351 billion tons of standard coal in 2000 to 3.319 billion tons of standard coal in 2012, an increase of 145.67%, and the annual primary energy consumption also increased from 1.455 billion tons of standard coal in 2000 to ...
