A highly economical energy heat conversion system and method with near-zero emission of carbon dioxide

Abstract

The invention provides a high-economical-efficiency energy source heat conversion system with near zero emission of carbon dioxide and a method. The system mainly comprises air separation equipment, pressure-bearing nitrogen separation equipment, pressure-bearing oxygen separation equipment, energy source heat conversion equipment, dust removing equipment, gas recycling equipment, carbon dioxide displacement equipment, heat recycling equipment, a draught fan, gas compression equipment and pressure-bearing combustible gas storage equipment. Fuel has an oxidization reaction in the energy source heat conversion equipment to generate high-temperature gas taking the carbon dioxide and water steam as main components; one part of the high-temperature gas enters the carbon dioxide displacement equipment and the carbon dioxide is reacted with the carbon-containing fuel to generate combustible gas, so that the near zero emission of the carbon dioxide is realized; the other part of the high-temperature gas enters the energy source heat conversion equipment again to keep the stable operation of the system. By utilizing the combustible gas, the economical efficiency of the energy source heat conversion system is greatly improved and disadvantages of a carbon dioxide emission reduction technology in an existing energy source heat conversion system are made up.

Description

technical field [0001] The invention belongs to the technical field of energy heat conversion, and relates to a highly economical energy heat conversion system and method with near-zero emission of carbon dioxide. Background technique [0002] Existing energy heat conversion systems emit a large amount of carbon dioxide during operation, which can have a bad impact on the earth's ecological environment. Controlling carbon dioxide emissions in the process of energy heat conversion has become a topic of common concern around the world, and different degrees of carbon dioxide emission reduction plans have been formulated for it. In 2013, my country's carbon dioxide emissions exceeded the sum of the United States and Europe, and the per capita carbon dioxide emissions also exceeded the European level for the first time. In 2014, my country promised in the "Sino-US Joint Statement on Climate Change" that carbon dioxide emissions will peak in 2030. However, my country's unique e...

AI Technical Summary

Problems solved by technology

[0004] (1) Carbon dioxide capture, compression, separation, purification, transportation, etc. lead to a significant decline in the efficiency and economy of the overall energy heat conversion system;

[0005] (2) The possibility of escape and leakage of stored carbon dioxide is extremely high

[0006] The above shortcomings also fundamentally limit the commercialization process of carbon dioxide capture and storage technology, which is not conducive to the realization of the national carbon dioxide emission reduction target
