Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection, and specifically to a multi-dimensional carbon dioxide collection and multi-element storage system. Background Art

[0002] Carbon dioxide, a carbon oxide compound with the chemical formula CO2 and a chemical formula weight of 44.0095, is a colorless and odorless or colorless and stinking gas at normal temperature and pressure, and its aqueous solution has a slightly sour taste. It is also a common greenhouse gas and one of the components of air. The boiling point of carbon dioxide is -78.5°C, the melting point is -56.6°C, its density is greater than that of air, and it is soluble in water.

[0003] With the acceleration of the industrialization process and the growth of the global population, the emissions of greenhouse gases such as carbon dioxide have increased sharply, leading to increasingly serious environmental problems such as global warming and sea-level rise. Traditionally, the carbon dioxide emission reduction strategy mainly relies on measures such as improving energy utilization efficiency and developing clean energy, but these methods are difficult to completely solve the problem of a large amount of already emitted carbon dioxide in the short term. Therefore, the development of efficient carbon dioxide collection and storage technologies has become one of the key ways to mitigate climate change.
