Supercritical carbon dioxide circulation and seawater desalination coupled vessel nuclear power system

Abstract

The invention discloses a supercritical carbon dioxide circulation and sea water desalination coupled vessel nuclear power system which comprises a reactor cabin, a ship cabin and a propelling device,the reactor cabin comprises a high-temperature gas cooled reactor system, and the ship cabin comprises a supercritical carbon dioxide power circulation system and a sea water desalination subsystem.A first-stage intermediate heat exchanger and a second-stage intermediate heat exchanger are arranged on the two sides of a high-temperature gas cooled reactor in the high-temperature gas cooled reactor system correspondingly. The supercritical carbon dioxide power circulation system is coupled with the high-temperature gas cooled reactor system through a first-stage intermediate heat exchanger and a second-stage intermediate heat exchanger. The seawater desalination subsystem is coupled with the supercritical carbon dioxide power circulation system through a precooler and an intercooler. Thepropelling device is connected with the supercritical carbon dioxide power circulation system. Vessel propulsion power and electric power are provided through the supercritical carbon dioxide circulation system, fresh water needed by the whole vessel is provided in cooperation with the sea water desalination system, the vessel is driven to sail in a direct propulsion mode, and the energy conversion rate and the device compactness are improved.

Description

technical field [0001] The invention relates to a power system, in particular to a ship nuclear power system coupled with a supercritical carbon dioxide cycle and seawater desalination. Background technique [0002] As one of the most critical parts of the overall system of a large ship, the power plant is the guarantee for the safe and stable operation of the ship, and the development of nuclear reactors to provide power for it is a common choice for all countries in the world. How to minimize its space and weight in the design of nuclear power plant is an important index to evaluate its design level. In view of the relatively low cycle efficiency and large equipment volume limitations of the traditional pressurized water reactor steam cycle power plant, the ship power system is optimized to design, and the development of a new power plant with both high performance and compactness is not only in line with the requirements of the national level. It is also one of the direc...
