Embodiment Construction

[0020] like figure 1 , figure 2 As shown, a dynamic solar energy comprehensive utilization greenhouse device in China is composed of a filter system, a heat collection system and accessories. Accessories include body of wall 2 and sink 9. The wall 2 serves as the main body of the greenhouse device to provide the growth space for the green plants 1 , the wall 2 is placed low in the south and high in the north, and the light filtering system is placed on the top of the wall 2 . In the filter system, the photonic crystal reflector 3 transmits the red and blue light in the solar spectrum for plant growth, and the remaining light quality is reflected and focused into the heat collection system. The heat collection system uses Chinese ink as the heat collection medium, and the flow of Chinese ink drives the rotation of the combined rotor of the unit, which produces a turbulent effect to enhance heat transfer and improve the efficiency of light-to-heat conversion.

Abstract

The invention discloses a dynamic Chinese-ink solar-comprehensive-utilization greenhouse device. Chinese ink is developed into efficient nano-fluid for solar photo-thermal utilization. The greenhouse device consists of a light filtering system, a heat collecting system and auxiliaries. In the light filtering system, red light and blue light of a solar spectrum can penetrate through a photonic crystal reflecting plate to be supplied to plant growth, and the rest light is reflected and focused into the heat collecting system; and the heat collecting system consists of two parts, i.e., a heat collecting tube and a heat insulating tube, a unit combined rotor is mounted in the heat collecting tube, the Chinese ink serves as a heat collecting medium, flows in the heat collecting tube section under the action of temperature difference and drives the combined rotor to rotate, a turbulent action is generated to strengthen heat transfer, the Chinese ink flows down from the heat insulating tube and is recovered through a hot-water pipe, and solar energy is stored and utilized in the form of heat energy. According to the greenhouse device, planting and heat collecting are integrated through the light splitting action of the photonic crystal reflecting plate; by adopting the Chinese ink, the heat absorption efficiency is increased, and the cost is reduced; and by a unit combined rotor dynamic system, the photo-thermal utilization efficiency is increased.

Description

technical field [0001] The invention relates to photothermal agriculture, in particular to nanofluids, and belongs to the field of efficient utilization of solar energy. Background technique [0002] Energy shortage and ecological crisis are becoming more and more severe, and the development and utilization of new energy sources are imminent. Clean and sufficient solar energy has become an important choice for energy conservation and emission reduction. At present, there are two main types of solar energy utilization: photovoltaic and photothermal. Photovoltaic technology is mature and widely used, but the production process of solar photovoltaic cells has a great impact on the environment, which is a production process with high energy consumption and high pollution. In contrast, solar thermal utilization is a clean production process, which basically uses physical means to convert photoelectric energy, which has minimal harm to the environment. As the name suggests, sola...
