Description
Technical Field
The invention relates to the technical field of purification treatment of smoke pollutants, in particular to a smoke waste heat utilization and carbon capture integrated system.
Background
The emission of greenhouse gases represented by carbon dioxide is an important cause of global warming, China has become the country with the largest emission amount of carbon dioxide, and in order to reduce the influence on the global environment, new technologies are required to be continuously developed to solve the problem of greenhouse gas emission. In recent years, the economic development of China is rapid, but along with huge energy consumption and carbon dioxide emission, China faces greater and greater carbon dioxide emission reduction pressure. The carbon dioxide emission in the electric power industry of China accounts for about 50% of the total national emission, the power generation capacity of a coal-fired power station accounts for about 78% of the total national power generation capacity due to the existing energy structure mainly using coal, and the research on the carbon dioxide emission reduction technology of a coal-fired boiler or a gas-fired boiler has great significance to China by considering part of coal-fired heat sources for heat supply and process heat.
The mature carbon dioxide trapping technology applied in China is mainly a post-combustion trapping method, is more suitable for modifying and upgrading the existing boiler, and has large amount of flue gas which can be processed. Chemical absorption methods are the most widely used method in post-combustion trapping technology, depending on the trapping effect and the complexity of the process. The method realizes the separation of carbon dioxide by the chemical reaction of the absorbent and the carbon dioxide in the flue gas, and then realizes the release of the carbon dioxide and the regeneration of the absorbent by the reverse reaction. The technology is mature and reliable, and the purity of the extracted carbon dioxide is high. The rich liquor in the process needs to be heated, the lean liquor needs to be cooled, and the high-temperature regeneration gas needs to be cooled. Since the release of carbon dioxide and the regeneration of the absorbent require a large amount of steam, there is a problem of high energy consumption and low economy, and the prior art has not solved the problem for a while, which causes a certain resistance to the popularization of the carbon dioxide capture technology.
