Embodiment 1

[0039] Embodiment 1: as Figure 1-Figure 3As shown in this embodiment, a single-tank stacked bed heat storage device with a bionic vein structure arranged in accordance with the generalized Murray's law is composed of a stacked bed heat storage tank, a heat storage bulb, and an inlet and outlet pipe section: The stacked bed heat storage tank includes a cylindrical main storage tank 1, a frustum-shaped auxiliary storage tank 2 at the upper end, and a truncated-shaped auxiliary storage tank 3 at the lower end. The auxiliary storage tank 2 is connected to the main storage tank 1 through a flange 6, and the auxiliary storage tank 3 is The flange 7 is connected to the main storage tank 1, the upper auxiliary storage tank 2 is connected to the heat transfer fluid inlet 4, and the upper auxiliary storage tank 3 is connected to the heat transfer fluid inlet 5; the cylindrical heat storage tank 1 is connected at the top and bottom respectively Add deflectors 8 and 9, and between the tw...

Embodiment 2

[0044] Embodiment 2: as Figure 4-Figure 6 As shown, this embodiment describes a single-tank stacked bed heat storage device with a bionic vein structure arranged in accordance with the generalized Murray's law. The difference between this embodiment and Example 1 is that the bionic vein structure is different. This embodiment is a rhombus bionic vein structure.

Embodiment 3

[0045] Embodiment 3: as Figure 7-Figure 9 As shown in this embodiment, a single-tank stacked bed heat storage device with a bionic vein structure arranged according to the generalized Murray's law, the difference between this embodiment and Example 1 or 2 is that the bionic vein structure is different, this embodiment It is an umbrella-shaped bionic vein structure.

[0046] In Example 1-3, a single-tank stacked bed heat storage device with a bionic vein structure arranged according to the generalized Murray's law, by changing the arrangement and size of the phase-change heat storage balls in the storage tank, the heat storage system Compared with traditional systems, it achieves higher heat storage efficiency, greater heat storage density and faster thermal response capability. The bionic vein structure adopted in this layout structure is a naturally selected efficient nutrient transport system, which has unique advantages in material transport and energy transfer.

Abstract

A single-tank packed bed heat storage device following the generalized Murray's law and provided with a bionic choroid structure and a using method thereof, and belongs to the field of energy storage.The problems of low heat storage density, small heat exchange area and uneven heat storage speed in a traditional packed bed heat storage system are solved. The heat storage device is characterized by comprising a storage tank, a bracket is arranged in the storage tank in the form of the bionic choroid structure, heat storage balls with different diameters following the generalized Murray's law are distributed in the storage tank, and the bracket is used for supporting the heat storage balls and preventing the heat storage balls from floating at will. The using method achieves heat storage, heat release and heat storage through the heat storage balls which follow the generalized Murray's law and are provided with the bionic choroid structure. By changing the arrangement mode and size of the heat storage balls in the storage tank, compared with the traditional system, the heat storage system achieves higher heat storage efficiency, higher heat storage density and faster thermal response capability, and the bionic choroid structure is a naturally selected efficient nutrient delivery system which has unique advantages in substance transportation and energy transfer.

Description

technical field [0001] The invention relates to a single-tank stacked-bed heat storage device, in particular to a single-tank stacked-bed heat storage device with a bionic vein structure arranged in accordance with the generalized Murray's law and a method for using the same, belonging to the technical field of energy storage. Background technique [0002] At present, research on solar energy is gradually increasing, but due to the periodicity of solar radiation, it is necessary to temporarily store the obtained energy. At present, it is mainly stored by heat storage tanks. The more common heat storage methods are divided into double-tank heat storage system and single-tank heat storage system. Among them, the commercial heat storage tank often adopts a double-tank heat storage system, which is composed of cold and hot double tanks, but the system costs a lot and occupies a large area. The single-tank heat storage system is also called thermocline heat storage. The heat sto...
