A transmission and utilization system of renewable energy

Abstract

The invention relates to a renewable energy source conveying and utilization system. The system comprises a renewable energy source factory, a low-temperature user, an expander, a generator, a high-temperature user and a conveying pipe rack. The conveying pipe rack is provided with a high-temperature high-pressure carbon dioxide pipeline, a low-temperature low-pressure carbon dioxide pipeline, a high-temperature low-pressure carbon dioxide pipeline and an oxygen conveying pipeline. The high-temperature high-pressure carbon dioxide pipeline is connected to an inlet of the expander; and an outlet of the expander is connected to the low-temperature low-pressure carbon dioxide pipeline. The low-temperature low-pressure carbon dioxide pipeline is connected to the high-temperature low-pressure carbon dioxide pipeline through the low-temperature user; and the high-temperature low-pressure carbon dioxide pipeline is connected to the renewable energy source factory through the high-temperature user. The system uses the conveying pipe rack to convey high-temperature high-pressure carbon dioxide, low-temperature low-pressure carbon dioxide and high-temperature low-pressure carbon dioxide, uses carbon dioxide as protective gas to convey oxygen, widens the utilization potential of carbon dioxide, effectively converts, stores, conveys and uses new energy, and realizes flexible adjustment and efficient utilization of energy.

Description

technical field [0001] The invention belongs to the technical field of new energy transmission and utilization, and relates to a renewable energy transmission and utilization system. Background technique [0002] At present, the source of air pollution is mainly produced by exhaust emissions from industrial kilns, mainly concentrated in the production of industrial kilns in high energy-consuming enterprises such as power plants and cement plants. Although renewable energy sources such as wind energy, solar energy, and tidal energy are cheap and clean, they are easily affected by natural conditions and the energy supply is unstable, and the generated electricity is also difficult to store. Carbon dioxide is the main greenhouse gas, but also an inexhaustible and cheap carbon and oxygen resource. Reducing carbon dioxide emissions and even lowering its concentration in the atmosphere has become a major challenge faced by all countries. [0003] The use of oxygen generation sys...
