Solar energy, sea water source heat pump, gas and supercritical carbon dioxide ship combined power generation system

Abstract

The invention discloses a power generating system integrating solar energy, a seawater source heat pump, fuel gas and a supercritical carbon dioxide ship. The power generating system comprises a solar heat collecting system, a seawater source heat pump system, a gas turbine power generating system and a supercritical carbon dioxide recompression Brayton-cycle power generating system. During working, the water source heat pump is utilized to extract low-grade heat energy from seawater, electric energy with less consumption is improved to be high-grade heat energy as a heat source of the supercritical carbon dioxide recycling system; meanwhile, the solar heat collector is adopted to acquire heat energy as the heat source of the supercritical carbon dioxide recycling system, and waste gas exhausted by a gas turbine and waste heat of heat exchange are recycled, so that gradient utilization of energy sources is realized; the supercritical carbon dioxide recompression Brayton-cycle power generating system adopts supercritical carbon dioxide as a working medium, is compact in power machinery structure and is good in economic performance; and the gas turbine power generating system and the supercritical carbon dioxide recompression Brayton-cycle power generating system are combined to realize stable ship combined power generation, and generated electric energy is finally input into a ship power grid.

Description

Technical field: [0001] The invention relates to a solar energy, seawater source heat pump, gas and supercritical carbon dioxide ship combined power generation system, which belongs to the field of energy conversion and is used for the utilization of solar energy and ocean energy and the application of supercritical carbon dioxide recompression Brayton power cycle. Background technique: [0002] Due to the rapid development of industry and manufacturing in recent years, the demand for traditional fossil fuels continues to rise, which directly leads to global energy shortages. The exhaust gas emitted directly after combustion will cause waste of waste heat resources and reduce the energy utilization of fossil fuels. Developing new energy utilization methods, using natural clean energy, recovering waste heat energy in exhaust gas, and improving energy utilization are currently feasible methods that can alleviate the energy crisis and the greenhouse effect.
