Abstract

The invention discloses a system for providing heat quantity for CCS (carbon dioxide capture and storage) by adopting a transcritical carbon dioxide heat pump, which belongs to the field of energy utilization and coal fired power generation. The system comprises two parts of a transcritical carbon dioxide heat pump system and the system for capturing carbon dioxide by a chemical absorption method in a coal-fired power plant, wherein the two parts are connected into the system capable of saving energy resources by a boiling unit 12, and the boiling unit 12 of the system capturing the carbon dioxide by the chemical absorption method in the coal-fired power plant is an air cooler of the transcritical carbon dioxide heat pump system. The heat pump device can improve the economical efficiency of the carbon dioxide captured by a chemical absorption method in the coal-fired power plant, and can reduce the water consumption amount of the coal-fired power plant.

Description

Technical field [0001] The invention belongs to the field of energy utilization and coal-fired power generation, and particularly relates to a system that adopts a transcritical carbon dioxide heat pump to provide heat for CCS (carbon dioxide capture and storage) of a coal-fired power plant. Specifically, the transcritical carbon dioxide high-temperature heat pump device is applied to the system for capturing carbon dioxide by chemical absorption in coal-fired power plants, thereby improving the economics of capturing carbon dioxide by chemical absorption in coal-fired power plants and reducing the water consumption of coal-fired power plants. At the same time, the resource utilization of carbon dioxide is also realized. Background technique [0002] The reduction of greenhouse gases such as carbon dioxide has attracted more and more attention from the international community and has become a hot spot in the international energy field. The core of the global response to climate ...
