Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide processing, and in particular to a carbon dioxide capture and storage device. Background Art

[0002] Currently, as the global climate continues to warm, CO2 is being emitted at a record rate around the world. While controlling greenhouse gas emissions has become a major goal for many countries in the world, the fact that climate change is causing damage and disasters in many places cannot be ignored, and there is also a large amount of carbon emissions in daily life.

[0003] However, some industries currently have large carbon emissions. For example, the flue gas or waste gas from coal-fired power plants, chemical plants, refineries, etc. contains more carbon dioxide. Therefore, when collecting the carbon dioxide, it is often necessary to set a capture device behind the flue gas emission port to capture the carbon dioxide. However, the emission ports have different specifications, so some capture devices have certain limitations when connecting, so this problem needs to be solved. At the same time, carbon dioxide capture is divided into many methods, such as chemical adsorption and physical adsorption. Some physical adsorption methods are prone to saturation of the adsorbent after long-term adsorption of carbon dioxide, thereby affecting the adsorption work, so this problem needs to be solved. Utility Model Content

At the same time, carbon dioxide capture is divided into many methods, such as chemical adsorption and physical adsorption. After long-term adsorption of carbon dioxide by some physical adsorption methods, the adsorbent is easily saturated, thereby affecting the adsorption work.
