Description
Technical Field
The invention belongs to the technical field of clean conversion of coal, and particularly relates to a pipe type direct carbon fuel cell poly-generation device and method.
Background
With the development of society and economy, energy and environment become two major problems that human beings must face, and especially after the economy of China enters the development stage of the new normality, the aspects of energy consumption, energy intensity, carbon emission and the like face new challenges and requirements, which are mainly reflected in the transformation of an energy structure, the improvement of energy efficiency, the low carbonization and the cleanness of the energy consumption structure and the like. From the energy structure at the present stage, the energy structure mainly based on coal consumption and the economic situation of high carbon characteristic in China are determined, and thereforeBringing about both energy and environmental stresses. Coal, as a main source of primary energy supply in China, accounts for over 50% of the total primary energy consumption for a long time and still dominates the energy structure in a long-term future. However, at present, coal is mainly converted into energy by direct combustion, the energy conversion efficiency is low due to the limitation of Carnot cycle, and the direct combustion process generates a large amount of CO2、NOxGreenhouse gases and harmful substances such as sulfide and dust bring huge pressure to the environment. In particular, the goals of "2030 carbon peak and 2060 carbon neutralization" are challenging to promote the coal utilization technology revolution. Therefore, the search for a cleaner and more efficient coal conversion mode becomes a hot research problem in the field of energy conversion and the coal utilization industry.
Aiming at the current energy technical situation of China, the state actively promotes the innovation action of the energy technical revolution, aims at the development direction of green low-carbon energy, puts forward the industrialization advantages of coal deep processing technologies such as coal gasification, liquefaction and pyrolysis in the aspect of traditional fossil energy utilization, actively promotes the industrial demonstration of low-rank coal grading and quality-based utilization, enhances the technical innovation of coal pyrolysis and semicoke utilization, researches and develops the coupling integration of related technologies such as coal chemical industry and fuel cells, and effectively realizes the energy gradient utilization and the material recycling.
Starting from the technical research field of clean coal, coal quality-based conversion is an effective way for realizing poly-generation and energy gradient utilization, and the method takes low-temperature pyrolysis of coal as a core to realize gas, liquid and solid separation of products and further efficiently converts and utilizes the products. However, the utilization of the semicoke is still mainly based on the traditional consumption mode, on one hand, the utilization efficiency is low, and on the other hand, the utilization market is limited. Therefore, the quality-divided conversion technology taking pyrolysis of low-rank coal as a core still faces the difficult problems of cleaning and efficient utilization of semicoke products.
As a fuel cell technology which is one of the important development fields of clean coal technology, a solution is provided for solving the energy and environmental problems due to environmental friendliness and high energy conversion efficiency. A fuel cell is a power generation device that directly converts chemical energy of fuel into electric energy, and is not limited by carnot cycle, so that it has high energy conversion efficiency and little environmental pollution, and is considered as the most potential power generation technology. Among fuels for fuel cells, carbon element is considered as a cell fuel with good development prospect due to high energy storage density and abundant reserves, and the realization of clean and efficient conversion of chemical energy of carbon-rich fuels such as coal, biomass, solid waste and the like into electric energy can effectively alleviate energy crisis and environmental pollution problems, so research on Direct Carbon Fuel Cells (DCFC) is receiving attention gradually.
The characteristics of a coal quality-based conversion technology and a direct carbon fuel cell technology are combined, and the development of coal fuel DCFC, semicoke fuel DCFC and coal pyrolysis and semicoke DCFC conversion integrated technology has important significance for realizing clean and efficient conversion of coal, expanding the semicoke utilization market, further extending the coal chemical industry chain and realizing the technical coupling of coal chemical industry and fuel cells.
