Ship supercritical carbon dioxide energy storage system

Abstract

The embodiment of the invention provides a ship supercritical carbon dioxide energy storage system. The ship supercritical carbon dioxide energy storage system comprises a first circulation subsystem,an intermediate heat exchanger, a second circulation subsystem and an energy storage subsystem, wherein the first circulation subsystem and the second circulation subsystem are thermally coupled through the intermediate heat exchanger, so that a supercritical carbon dioxide working medium in the second circulation subsystem exchanges heat to form a high-temperature supercritical carbon dioxide working medium; and the second circulation subsystem is connected with the energy storage subsystem, so that a medium in the energy storage subsystem exchanges heat with the high-temperature supercritical carbon dioxide working medium to form heat energy and cold energy. According to the ship supercritical carbon dioxide energy storage system, energy storage in a limited space is realized while electric power is provided for a ship; and when the ship needs to be changed, the energy storage subsystem releases energy and generates electric energy, so that the ship supercritical carbon dioxide energy storage system can be switched under various working conditions, and the energy utilization rate and the variable working condition sensitivity of a power system are improved.

Description

technical field [0001] The invention relates to the technical field of ship power, in particular to a ship supercritical carbon dioxide energy storage system. Background technique [0002] The power system is an important part of marine platforms such as ships, which directly determines the speed, endurance, mobility, energy and electricity required for daily operation and personnel life of the offshore platform. The Arctic region has a special geographical and natural environment and is rich in various resources. It has gradually become the focus of the development of various maritime powers. Nuclear-powered icebreakers are important equipment for the development of polar marine resources and polar exploration. Compared with conventional-powered icebreakers, nuclear-powered icebreakers have more endurance Long time, good economy and other advantages. The pressurized water reactor combined with the steam Rankine cycle is currently a relatively common form of power system fo...
