[0002] Large amounts of carbon dioxide emissions will mainly cause the greenhouse effect. For chemical production, carbon dioxide can be recycled and reused, which can not only reduce pollution to the environment, but also improve resource utilization efficiency. Carbon dioxide capture technology can be divided into several categories, including chemical absorption, physical absorption, physical adsorption, membrane separation, and cryogenic separation. Physical absorption capture uses the property that the solubility of certain physical solvents in carbon dioxide is much greater than that of other components in flue gas to separate carbon dioxide from other components.

[0003] However, the existing collectors for capturing carbon dioxide do not have a filtering structure, which causes particulate matter in the flue gas, such as dust, to enter the solution containing dissolved carbon dioxide, causing contamination of the solution and making it inconvenient to use. Therefore, a point source collector for capturing carbon dioxide is urgently needed to solve the above problems. Utility Model Content
