Heterogeneous multi-heat-source co-storage device

Abstract

The invention relates to a heterogeneous multi-heat-source co-storage device. The heterogeneous multi-heat-source co-storage device comprises a shell, wherein multiple phase change areas are arranged in the shell, and each phase change area is filled with a phase change material, and each phase change area forms a respective heat storage unit; heat storage pipes, wherein one heat storage pipe is arranged in each phase change area of each heat storage unit; and heat release pipes, wherein the heat release pipes sequentially penetrate through the phase change areas of the heat storage units according to a sequence from low-temperature areas to high-temperature areas, or each phase change area is provided with one heat release pipe, and the parts, located on the outer side of the shell, of the heat release pipes of the adjacent phase change areas are connected with each other or the heat release pipes of the adjacent phase change areas exist independently. The heat storage pipes transfer heat of heat sources to the phase change materials, the heat storage pipes in different phase change areas can be connected with different heat sources, multi-heat-source co-storage is achieved, the heat release pipes penetrate through the multiple phase change areas and can conduct heat exchange on the phase change materials in different areas at the same time, heat storage is conducted through different heat sources, and the supply stability of heat can be met; and the adaptation to different heat source environments is facilitated.

Problems solved by technology

Sensible heat and thermochemical heat storage technology have the disadvantages of low heat storage density, large temperature fluctuations in the heat storage and release process, and unstable heat load.

Moreover, the inventors found that in the vast rural areas, it is generally in the form of non-centralized heating. At the present stage, it is mainly coal-fired, with other forms of heat sources, and the utilization rate of heat energy from different heat sources is low. Satisfy the stable heat utilization temperature range, let alone achieve the goal of carbon emission reduction
