The invention discloses a solar photovoltaic driven aquo-complex method carbon capture system which comprises a solar photovoltaic power generation unit and an aquo-complex method carbon capture unit.The aquo-complex method carbon capture unit comprises a gas booster pump, an electric control valve, a thermostatic bath, a temperature control box, a four-way reversing valve, a pressure adjuster, a vacuum pump, at least one set of dual-reaction tower structures and the like.The solar photovoltaic power generation unit can provide all electric power for power consumption equipment of the aquo-complex carbon capture unit.Due to the addition of an energy storage device in the solar power generation unit, continuity of power supply to the power consumption equipment of the aquo-complex method carbon capture unit can be ensured; the aquo-complex method carbon capture unit adopts the dual-reaction tower circulation mode, continuity of the aquo-complex method carbon capture process can be ensured, the carbon dioxide capture rate is increased, and the gas generation rate is increased.The requirement for carbon dioxide capture is met, and the purposes of effectively utilizing renewable energy sources and lowering energy consumption of a power plant capture system are achieved.

Description

technical field [0001] The invention relates to the technical field of solar energy assisted carbon capture, in particular to a solar photovoltaic driven continuous hydrate carbon capture system. With solar photovoltaic power generation technology and hydrate carbon capture technology as the core, it meets the needs of capturing carbon dioxide. 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. Coal-fired power plants are the largest source of carbon dioxide emissions, and controlling their carbon dioxide emissions is highly focus on. The current main measure is carbon capture and storage (CCS) for flue gas. The existing carbon capture technologies can be divided into post-combustion capture, pre-combustion capture and oxygen-enriched combustion capture, among which the most widely u...

Problems solved by technology

However, the above patents are only aimed at the combination of solar energy utilization and absorption carbon capture, and do not involve other capture methods. However, the regeneration energy consumption of absorption carbon capture itself is relatively high. If the energy consumption of the carbon capture system is 100 If the power plant is supplied by solar energy, the economic benefits of the power plant will be greatly reduced, which limits the development of solar-assisted absorption carbon capture technology

[0011] Based on the above, it can be seen that the existing relevant patents cannot well achieve the ideal goal of reducing carbon capture energy consumption and effectively mitigating greenhouse gas emissions. At present, there is an urgent need to develop a low-energy-consumption system that uses solar energy to assist Hydrate carbon capture system
