Description
Technical Field
The invention relates to the technical field of combustion tail gas treatment, in particular to the field of equipment for reoxidizing incompletely combusted oxides in combustion tail gas, and specifically relates to a tail gas reoxidation device utilizing a smoke exhaust pipeline for removing acidic oxides.
Background
With the development of industry and the proliferation of population, the massive carbon dioxide emitted by human activities has a bad influence on the sustainable development of environment, and global warming is one of the main manifestations of environmental deterioration. Carbon dioxide, the major source of greenhouse gas, is the combustion of fossil fuels, which will continue to dominate production within the next decades of human society development, and thus the capture and utilization of carbon dioxide is of great importance in reducing greenhouse gas emissions.
The flue gas mainly contains nitrogen and carbon dioxide, and the flue gas of the coal-fired boiler also contains gases such as sulfur oxides and nitrogen oxides, dust and the like, so how to separate the carbon dioxide from the nitrogen efficiently is a key step for capturing and recovering the carbon dioxide in the flue gas. The content of carbon dioxide in the flue gas is lower and is in the proportion range of 8-15 percent. The selectivity of separating the two gases by adopting a physical adsorption method is low; the chemical absorption method has higher corrosivity and too large amine loss; the low temperature process is too capital intensive and occupies a large area, and new separation facilities and separation technologies need to be developed and sought. In recent years, the development of membrane separation methods has been rapid, which is mainly attributed to the advantages of simple operation, low cost investment, low energy consumption, excellent separation performance and the like. The membrane which is put into industrial production at present is a polymer membrane, but the membrane is influenced by the mutual restriction of permeability and selectivity, and the membrane material can be plasticized after long-time operation under the condition of high pressure; although the inorganic film has excellent performance, the preparation process is often complex, the preparation period is long, and the inorganic film is not suitable for large-scale industrial production. The metal organic framework membrane integrates the advantages of an organic membrane and an inorganic membrane, and is formed by combining metal ions or ion clusters and organic ligands, so that the metal organic framework membrane is obtained by periodic arrangement, and further integrates inorganic performance and organic performance, and can be widely applied to the aspects of gas sensing, catalysis, separation and the like.
In the prior art, the treatment of the acidic oxides in the flue gas is mainly used for treating the sulfur nitrogen oxides, the removal of carbon dioxide is generally not considered, and alkaline solvents or materials are adopted for one-time absorption.
