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.
