DEVICE, INDUSTRIAL INSTALLATION AND METHOD WITH HIGH ENERGY EFFICIENCY FOR ACCUMULATION AND USE OF THE HEAT ENERGY OF THE SUN

摘要

1. A device (1) for accumulating and releasing thermal energy, designed to receive focused solar radiation and containing: - at least one layer (3, 30) of fluidized particles located at least partially near the sensing surface (20 ) such radiation; - supply means (14, 142, 21) providing a supply of fluidizing gas for fluidizing said particles; and - heat exchange elements (4) through which the working fluid flows during operation and which are installed inside or in the immediate vicinity of the bed (3, 30) of fluidized particles, while the general design is such that in the operating mode the parts (3, 30 ) of the said layer of particles can be selectively driven by a fluidizing gas to accumulate heat energy received from solar radiation at the stage of heat storage, and to transfer the stored heat to heat exchange elements (4) at the stage of heat release, and the general layout is such that it allows you to independently activate the stage of heat storage and stage heat. 2. The device (1) according to claim 1, in which the particle layer, in turn, contains: - a first storage part (30), designed to store thermal energy received from focused solar radiation and located next to the surface (20) that receives solar radiation; and - the second heat-generating part (3) adjacent to the first part (30) and designed to transfer heat energy accumulated by the first part (30) to the heat exchange elements (4), while the first part (30) and the second part (3) are intended to implement
