A solar photothermal coupling hydrogen production device based on frequency division technology

Abstract

The invention discloses a solar photothermal coupling hydrogen production device based on frequency division technology, which includes a photothermal coupling reactor and a liquid storage tank; Above, the middle of the liquid storage tank is connected through a temperature-controlling fluid layer, and the photothermal coupling reactor is wrapped in the temperature-controlling fluid layer. Right below the photothermal coupling reactor, two solid-state frequency dividers are symmetrically arranged, and the two sides of the liquid storage tank A heat-absorbing fluid layer and a vacuum layer are arranged on the inner side of the side in turn, and several reflectors are arranged side by side directly under the liquid storage tank; when working, the test sample containing the photothermal catalyst is placed in the photothermal coupling reactor, and the light source passes through the solid state separation The frequency converter divides the light source into an infrared part and an ultraviolet part. The energy of the infrared part is finally transferred to the photothermal coupling reactor, and the ultraviolet part is projected onto the photothermal catalyst. The invention is used for the photothermal coupling hydrogen production experiment 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...
