Solar photothermal coupling hydrogen-production device based on frequency division technology

Abstract

The invention discloses a solar photothermal coupling hydrogen-production device based on a frequency division technology. The device comprises a photothermal coupling reactor and a liquid storage tank, wherein an circular arc secondary reflection component has a downward opening, and is disposed right above the liquid storage tank, the middle of the liquid storage tank communicates through a temperature-control fluid layer, and the photothermal coupling reactor is wrapped in the temperature-control fluid layer; and two solid frequency dividers are symmetrically disposed directly below the photothermal coupling reactor, an endothermic fluid layer and a vacuum layer are sequentially arranged at the inner sides of two sides of the liquid storage tank, and a plurality of mirrors are arrangedside by side directly below the liquid storage tank. During operation, a test sample containing a photothermal catalyst is put in the photothermal coupling reactor, and a light source is divided intoan infrared light part and an ultraviolet light part through the solid frequency dividers; and the energy of the infrared light part is finally transmitted to the photothermal coupling reactor, and the energy of the ultraviolet light part is projected onto the photothermal catalyst. The device is applied to photothermal coupling hydrogen production experiments of catalyst particles, and has the advantages of environmental protection, high efficiency, simple and convenient operation and the like.

Description

technical field [0001] The invention belongs to the technical field of new energy preparation, and in particular relates to a solar photothermal coupling hydrogen production device based on frequency division technology. Background technique [0002] In recent years, the United States, Japan and Europe have launched fierce competition in the commercialization of hydrogen fuel cell vehicles. The Chinese government is also actively promoting the development of the hydrogen energy industry. Hydrogen fuel cell energy supply technology has been rapidly advancing to commercialization. However, my country has not yet formed Complete hydrogen energy supply technology system, immature key technologies such as hydrogen storage and hydrogen transportation, weak hydrogen energy supply industry chain, weak hydrogenation enterprises, and few hydrogen purification, storage and transportation enterprises. Therefore, the development of hydrogen production technology Still very necessary. Hydr...
