Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a device for removing carbon dioxide in waste gas. Background technique [0002] As we all know, the atmospheric greenhouse effect is the biggest environmental problem faced by mankind at present. The climate anomalies, sea level rise, land desertification and other problems brought about by the greenhouse effect are threatening the survival and development of human beings. [0003] Among the six main gases that produce the greenhouse effect (CO 2 、CH 4 , N 2 O. HFCs S 、PFC S , SF 6 ), CO 2 It has the greatest effect on the greenhouse effect, accounting for about 55%. It can be seen that controlling CO 2 Emissions are key to controlling the greenhouse effect. Under such circumstances, the "United Nations Framework Convention on Climate Change" and the "Kyoto Protocol" were promulgated successively, systematically discussing the content involved in the lo...
