Description

technical field [0001] The invention relates to the technical field of solar energy assisted carbon capture, in particular to a solar photothermal assisted temperature swing adsorption carbon capture system. With solar thermal utilization technology and temperature swing adsorption carbon capture technology as the core, it meets the demand for capturing carbon dioxide under low energy consumption. Background technique [0002] The fifth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC) shows that the concentration of carbon dioxide in the atmosphere has been 40% higher than before industrialization. As the most important greenhouse gas, excessive emissions of carbon dioxide will cause the greenhouse effect and climate change. Therefore, it is crucial to control CO2 emissions from large sources of CO2 emissions such as power plants, cement plants and chemical plants. The current main measure is to use carbon capture and storage (CCS) te...

Problems solved by technology

However, most of the above patents are aimed at the combination of solar energy utilization and absorption carbon capture. However, the regeneration energy consumption of absorption carbon capture itself is relatively high, which limits the development of carbon capture technology.

In addition, solar photovoltaic assisted carbon capture technology will face the cost and life of photovoltaic panels, and the production process of photovoltaic panels will consume a lot of energy

[0011] Based on the above, it can be seen that the existing related patents cannot well achieve the ideal goal of reducing carbon capture energy consumption and effectively mitigating greenhouse gas emissions. Temperature swing adsorption carbon capture system
