Deep-sea carbon storage and power generation system

Abstract

The invention discloses a deep-sea carbon storage and power generation system. The deep-sea carbon storage and power generation system comprises a waste heat turbine, a waste gas heat exchanger, a gasstripping device, a waste gas treatment device, a supercritical carbon dioxide compressor, wave energy power generation equipment, a geothermal heat exchanger, a supercritical carbon dioxide turbineand a seabed cooler. According to the deep-sea carbon storage and power generation system disclosed by the invention, waste heat power generation and carbon dioxide stripping are performed on power plant waste gas, and the stripped carbon dioxide is applied to a seabed geothermal Brayton cycle, and is finally stored in deep-sea storage holes. The system is compact in structure, is small in size and is high in efficiency. Rich seabed geothermal energy is used as a heat source, is free of pollution and is low in cost; carbon dioxide is stored in the form of carbon dioxide hydrate, is relativelylow in cost, is environmentally-friendly and is good in leakproofness; and a dried oilfield, gas field or natural hole with a good storage cover in a seabed geologic body is utilized as a carbon storage site, so that the storage effect is good, and later-period maintaining and monitoring cost is reduced, and therefore, the system has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection technology and new energy power generation, and in particular relates to a deep-sea carbon sequestration and power generation system. Background technique [0002] With the continuous development of the industrialization process and the continuous progress of society, human beings have an increasing demand for fossil energy. The air pollution and greenhouse effect caused by the burning of fossil fuels have seriously endangered the earth environment on which human beings depend. Global warming has caused a series of global problems such as melting glaciers and rising sea levels. Countries around the world have gradually realized the ecological and environmental problems caused by global warming, and began to explore long-term effective solutions from the aspects of technology, economy, policy and law. Mitigate the trend of global warming. At present, there are two main solutions....

Problems solved by technology

The capture and storage of carbon dioxide emitted by coal-fired power plants is of great significance for mitigating the greenhouse effect. However, the technology of carbon dioxide capture and storage consumes a lot of energy and is not yet mature. Currently, only a small number of power plants use it to reduce the energy consumption of carbon dioxide carbon sequestration. Improving the carbon sequestration efficiency of carbon dioxide is the focus of domestic and foreign research
