Embodiment 1

[0028] Embodiment 1: The basic principle of the Stirling solar combined heat and power system in this embodiment is to generate high heat density solar energy through dish concentrators (groups) to heat the heat transfer fluid (air), and then use the hot air directly or Indirectly transport heat energy to the Stirling engine power generation unit in the system to generate electricity, thus realizing the energy conversion process of "light-heat-electricity". The system is mainly composed of heat collection device 1, heat storage device 2, Stirling generator set 3 and monitoring system.

[0029] The heat collecting device 1 is a group of dish-type concentrators, and a trough-type or tower-type concentrator can also be used. The dish concentrator is a curved reflector in the shape of a rotating parabola. Its function is to collect solar radiation energy, gather the collected energy through pipes, and then supply the energy to the heat storage unit or energy conversion unit. The ...

Embodiment 3

[0067] Embodiment 3: On the basis of Embodiment 2, an air-water heat exchanger 13, a 3-way valve 5, a 3-way valve 6 and heat exchange pipelines are added. The Stirling generator set 3 is connected to the air-water heat exchanger 13, and the air-water heat exchanger 13 is respectively connected to the hot water storage tank 5 and the circulating water pump 9.

[0068] The heat collection device 1, heat storage device 2 and Stirling generator set 3 are connected through a hot gas circulation pipeline, and the gas direction is controlled by a heat storage fan 7 and a circulation fan 6 in cooperation with several direction and flow controllable 3-way valves , realize heat storage and power generation functions respectively.

[0069] The Stirling generator set 3 absorbs the heat from the heat collection device 1 or the heat storage device 2 to generate electricity, and transmits it to the grid through a transformer 8 .

[0070] During the working process of the Stirling generator ...

Abstract

The invention discloses a heat-storage voltage-stabilized stirling power generation system, which comprises a heat collecting device (1), a stirling generator set (3) and a circulating pipe, wherein a heat storage device (2) is arranged between the heat collecting device (1) and the stirling generator set (3); a heat transfer medium from the stirling generator set (3) enters the heat collecting device (1) or the heat storage device (2); the heat transfer medium heated through the heat collecting device (1) enters the heat storage device (2) or the stirling generator set (3); and the heat transfer medium in the heat storage device (2) enters the stirling generator set. Solar radiation energy absorbed during the day is stored in a form of heat energy by using the heat storage device, and the flow of the heat energy is adjusted through a controller, so that the heat energy entering a stirling generator is kept at a relatively stable value, and is released for thermal power generation during the night or when the light is insufficient in a cloudy sky, and a power station continuously and stably generates electricity.

Description

technical field [0001] The invention relates to a Stirling power generation and heating system. Background technique [0002] Under the situation of increasingly tense energy sources, countries all over the world are striving to develop clean new energy sources. As a clean and environmentally friendly natural energy with unlimited reserves, solar energy accounts for an increasing proportion of the types of energy used by human beings. The ways of solar energy utilization can be mainly divided into four categories: photothermal conversion, photoelectric conversion, photochemical conversion and photobiological conversion; among them, photothermal conversion and photoelectric conversion are the most widely used and most common. At present, there are three main types of solar thermal power generation: trough system, tower system and dish system. Among the three, dish Stirling solar thermal power generation technology has the advantages of the highest conversion efficiency, the ...
