Description

Technical Field

[0001] The utility model relates to the technical field of carbon removal, in particular to a carbon dioxide gas carbon removal device. Background Art

[0002] A decarbonizer is a device used to remove carbon dioxide (CO2) produced during the combustion process. The decarbonizer mainly converts carbon dioxide into other substances through chemical reactions to achieve the purpose of removal. The most commonly used method is to use sodium hydroxide (NaOH) or calcium hydroxide (Ca(OH)2) as absorbents. These absorbents react with carbon dioxide to form carbonates, such as sodium hydroxide reacting with carbon dioxide to form sodium carbonate.

[0003] In the existing carbon dioxide removal, carbon dioxide gas is often directly introduced into the solution with absorbent. However, the natural contact between the absorbent and carbon dioxide is small, which is not conducive to the absorption of carbon dioxide and affects the absorption efficiency. Therefore, we propose a carbon dioxide gas decarbonization device. Utility Model Content
