Abstract

The invention discloses an improved hybrid energy-storage single tank. The improved hybrid energy-storage single tank comprises a phase-change heat accumulator, a thermocline heat-storage single tank,molten salt, phase-change heat-accumulation materials, shell and tube heat exchanger pipelines, a large quantity of porous medium filler, an upper air diffuser and a lower air diffuser. The phase-change heat accumulator is tightly connected with the thermocline heat-storage single tank in the vertical direction. The thermocline heat-storage single tank is filled with the porous medium filler. Theshell and tube heat exchanger pipelines and the phase-change heat-accumulation materials are evenly arranged in the phase-change heat accumulator. The interior of each shell and tube heat exchanger pipeline is of a corrugated pipe structure. The upper air diffuser is mounted on the upper portion of the phase-change heat accumulator and is externally connected with a top inlet of a tank body. Thelower air diffuser is mounted on the lower portion of the thermocline heat-storage single tank and is externally connected with a bottom outlet of the tank body. The heat storage and release efficiency of the heat-storage tank is improved, and the effective heat storage and release capacity of the heat-storage tank is improved; and compared with a double-tank heat-storage system, the improved hybrid energy-storage single tank has the advantages of being simple in structure and low in investment cost.

Description

technical field [0001] The invention relates to the technical field of heat exchangers and heat storage tanks, in particular to an improved hybrid heat storage single tank. Background technique [0002] Heat storage technology currently mainly includes sensible heat storage, latent heat storage, chemical reaction heat storage and phase change heat storage. Since the latent heat of a substance is much greater than the sensible heat, and the phase change material maintains a constant temperature when the phase change occurs, the phase change heat storage technology has the advantages of high energy storage density and small temperature fluctuation range during the heat release process. For solar thermal power plants, phase change heat storage is the most important application form of solar heat utilization. Among them, the most widely used heat storage system is the double-tank heat storage system, but during the working process of the double-tank heat storage system, the tank...
