Abstract: The present application discloses a method and an apparatus for solar power generation through gas volumetric heat absorption based on characteristic absorption spectrum. A radiation energy conversion device absorbs concentrated solar radiation and converts radiation energy into thermal energy; the thermal energy is transferred to the other side of the radiation energy conversion device and then is converted into radiation energy; and the energy is transferred in a receiver cavity. The working gas from the outlet of a recuperator flows into the receiver cavity and absorbs the radiation energy. The heated working gas with high temperature flows into a turbine, doing shaft work through expansion. The expanded working gas flows through the recuperator to exchange heat. The working gas flows into a cooler, a compressor and the recuperator in sequence, and then flows into a receiver cavity to be heated volumetrically, completing a thermal power cycle.

Abstract: The present invention is related a square packed tower for collection of flue gas CO2. The square packed tower comprises an initial absorbent distributor on the lower end of the flue gas outlet, a vertical plate packer on the lower end of the initial absorbent distributor and a radial diversion gas distributor at the bottom of the square packed tower for delivery of carbon dioxide contained in the flue gas. The radial diversion gas distributor comprises a gas inlet pipe, a butterfly base plate, a butterfly seal plate and numerous radial deflectors. The butterfly base plate is connected with outlet of the gas inlet pipe. The radial deflectors are in radial arrangement between the butterfly base plate and butterfly seal plate along the outlet of gas inlet pipe. Such square packed tower has solved such problems as low mass transfer efficiency, uneven distribution of gas phase inside the tower and high investment.

Abstract: A far-field radiative thermal rectification device uses a phase change material to achieve a high degree of asymmetry in radiative heat transfer. The device has a multilayer structure on one side and a blackbody on other side. The multilayer structure can consist of a transparent thin film of KBr sandwiched between a thin film of VO2 and a reflecting layer of gold. When VO2 is in its insulating phase, the structure is highly reflective due to the two transparent layers on highly reflective gold. When VO2 is in the metallic phase, Fabry-Perot type of resonance occurs and the tri-layer structure acts like a wide-angle antireflection coating achieved by destructive interference of partially reflected waves making it highly absorptive for majority of spectral range of thermal radiation. The instant structure can form the active part of a configuration that acts like a far-field radiative thermal diode.
