Description
Technical Field
The invention relates to the technical field of carbon dioxide gas treatment, in particular to multidimensional normal-pressure purification equipment for carbon dioxide.
Background
The carbon dioxide emission in China strives to reach a peak value 2030 years ago, and strives to achieve carbon neutralization 2060 years ago. Carbon peak reaching means that the emission of carbon dioxide does not increase until 2030 years of commitment in China, and the emission of carbon dioxide gradually decreases after the carbon peak reaching. Carbon neutralization means that enterprises, groups or individuals measure and calculate the total amount of greenhouse gas emission generated directly or indirectly within a certain time, and then the emission of carbon dioxide generated by the enterprises, the groups or the individuals is counteracted through the forms of afforestation, energy conservation, emission reduction and the like, so that zero emission of the carbon dioxide is realized.
The carbon dioxide in the atmosphere mainly comes from six aspects of power generation, transportation, industry, building industry and animal and plant respiration. Among them, the main sources of anthropogenic carbon dioxide emissions are fossil fuel combustion in energy production and transportation, and many hundreds of plants and power stations and motor vehicles powered by fossil fuels worldwide, and their exhaust gases are the main sources of atmospheric carbon dioxide. The harm of carbon dioxide to human beings is mainly reflected in the following two aspects. Most typically the greenhouse effect, which causes the glaciers to melt and the sea level to rise. Greenhouse effect can also affect the circulation of the atmosphere, change the water circulation of the earth and further change the global precipitation distribution. The greenhouse effect seriously influences the production, life and social and economic development of people, and causes huge economic loss. Carbon dioxide, on the other hand, is a carbon resource. The high-concentration carbon dioxide can be applied to the fields of medical treatment, food, welding and the like. Due to its wide application, carbon dioxide recovery technology has become one of the focuses of research concerns in countries around the world.
At present, the mainstream carbon dioxide recovery process at home and abroad is an MEA process and a pressure swing adsorption process.
Wherein the MEA process is a chemical absorption method and means utilizing CO 2 Reacting with absorbent to form a weakly bonded intermediate compound, and changing the conditions to enrich CO 2 Absorbing liquid of (2) CO 2 The absorbent can be regenerated by desorption. A typical chemical absorbent is Monoethanolamine (MEA). The method has some defects, so that the popularization and the application are limited, for example, the solvent needs to be heated during regeneration, the energy consumption is high, the operation cost is high when the method is used in the power industry, and the problems of air pollution, easy oxidative degradation, serious corrosion to equipment and the like exist.
The pressure swing adsorption method mainly utilizes the characteristic that the adsorption capacity of an adsorbent to gas changes along with the pressure change, the adsorbent is used for pressurizing and adsorbing carbon dioxide components in the gas under the condition of selective adsorption, and the components are decompressed and desorbed to regenerate the adsorbent, so that the separation of the carbon dioxide components and impurity components is realized, and meanwhile, the adsorbent is regenerated. Each adsorber must go through two stages of adsorption and regeneration in a practical process. It follows that the adsorption process is intermittent for each adsorber and multiple adsorber cycles must be employed.
