Abstract

The invention relates to a hydride heat storage system adopting direct illumination heating. The system comprises a heat exchange tank, wherein a first light-transmitting module allowing sunlight to pass through is arranged on the side face of the heat exchange tank, and the heat exchange tank is provided with a flow inlet and a flow outlet allowing a heat exchange medium to come in and go out. Aplurality of heat storage reactors playing a baffling role are alternately arranged on the upper inner wall surface and the lower inner wall surface of the heat exchange tank correspondingly, each heat storage reactor is provided with a hydrogen valve connected with an external hydrogen storage container, and second light-transmitting modules matched with the first light-transmitting module are arranged on the side surfaces of the heat storage reactors (1). When the system is installed, metal hydride and heat radiation reinforced particles which are arranged in a mutually mixed mode are placedin the plurality of heat storage reactors. By the adoption of the technical scheme, efficient heat storage of the metal hydride heat storage system is achieved; and meanwhile, the structure is simple, economical and practical.

Description

technical field [0001] The invention relates to the technical field of solar thermal energy storage, in particular to a hydride heat storage system and method for direct sunlight heating. Background technique [0002] Since the beginning of the 21st century, energy crises and environmental degradation have occurred worldwide, forcing human society to develop various renewable and clean energy sources. Solar energy is an abundant renewable energy source that has attracted extensive attention from researchers. Solar thermal power generation technology is the development direction of a new generation of solar power stations. Among them, the heat storage system is a key component of solar thermal power generation, which can enhance the stability and continuity of power supply of solar thermal power plants. [0003] Heat storage material is the key technology of heat storage system. The types of heat storage materials are mainly divided into sensible heat storage materials, la...
