The invention discloses a composite combined supply system based on natural gas reforming hydrogen production and a fuel cell. The composite combined supply system comprises a natural gas hydrogen production system, an absorption refrigeration system, a Brayton cycle system, the fuel cell, an organic Rankine cycle system and an energy supply system. The natural gas hydrogen production system is used for reforming hydrogen production by taking natural gas as a raw material through a heat source provided by a Brayton cycle; the absorption type refrigeration system is driven by a part of heat sources provided by the Brayton cycle, cold energy required by condensation of the absorption type refrigeration system is provided by the organic Rankine cycle, and the absorption type refrigeration system is responsible for cold supply of a user; the Brayton cycle system supplies energy by combusting natural gas, one part of the Brayton cycle system is used for reforming hydrogen production, the other part of the Brayton cycle system acts on a gas turbine, and tail gas after acting is sequentially used for preheating inlet gas of a fuel cell and used as a heat source of an organic Rankine cycle; the fuel cell takes natural gas as a raw material for reaction power generation, and generated waste gas continues to supply heat to users after driving the operation of the organic Rankine cycle. Combined supply of cold, heat, electricity and hydrogen is flexibly achieved, and the purposes of energy conservation and emission reduction are achieved.
Description
technical field [0001] The invention relates to an energy utilization technology, in particular to a combined combined supply system based on natural gas reforming to produce hydrogen and a fuel cell. Background technique [0002] Energy is the cornerstone of human survival and development. With the rapid economic and social development today, fossil energy can no longer meet the requirements of green and clean development. As non-renewable energy, the depletion of fossil energy has prompted people to look for its substitutes. Among many energy sources, hydrogen energy has gradually attracted people's attention and been valued. [0003] Hydrogen energy has the advantages of a wide range of sources, clean and environmentally friendly, efficient and flexible, and a wide range of applications. In my country, the application of hydrogen energy in the industrial field is relatively mature, but in the long run, the traditional industrial hydrogen production method has certain hea...
