A solar Stirling power generation system

Abstract

The invention relates to a solar Stirling power generating system. The solar Stirling power generating system comprises a dish-type condenser, a solar collector, an energy storing device and a Stirling power generator; the dish-type condenser is used for reflecting and gathering sunlight, the solar collector is used for absorbing solar radiation and converting solar energy into heat energy; the solar collector and the energy storing device are connected through a flexible high-temperature heat pipe; and the energy storing device and the Stirling power generator adopt contact connection. According to the solar Stirling power generating system, on the overall structure, the solar collector and the energy storing device as well as the solar collector and the Stirling power generator are arranged in a separated mode, the flexible heat pipe is adopted to enable the solar collector and the energy storing device to be connected, thus separation of the solar collector and the energy storing device as well as the solar collector and the Stirling power generator is achieved to enable the mass and the size of the energy storing device not to be limited, high-capacity heat storing can be achieved, and the solar Stirling power generating system is more suitable for being applied to an energy-storing type large-power Stirling power generating system.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar Stirling power generation system. Background technique [0002] With the continuous increase of global energy consumption and the decrease of non-renewable energy such as petroleum, energy shortage has become a major problem affecting people's life and restricting social development. Countries all over the world are trying to increase the development and utilization of renewable energy. Among the many types of renewable energy, solar energy resources are very rich, which is very important to the development and utilization of solar energy, especially the development and utilization of solar power generation technology. [0003] In solar power generation technology, concentrating solar Stirling power generation has received a lot of research because of its high power generation efficiency, and has a good application prospect. Different from traditional powe...

Problems solved by technology

[0004] However, the currently widely used integrated solar heat storage Stirling power generation system integrates heat collection, heat storage, and power generation systems and distributes them at the concentrating points of dish-type concentrating panels. Demand for capacity heat storage and continuous and uninterrupted power generation

Although high-power and long-term energy storage can be achieved by increasing the size and quality of the integrated heat storage and power generation device, it will have many adverse effects on the entire system: the increase in the size of the heat storage and power generation device will reduce the light-receiving area of ​​the dish concentrator , reduce the light concentration efficiency of the system, increase the mass of the heat storage power generation device, increase the load of the solar light tracking system, and increase the center of gravity of the entire system, which is not conducive to the installation, maintenance and mechanical stability of the entire device
