Problems solved by technology
However, although the device adopts a split design, the energy storage materials in each unit layer are still simply piled up, the problem of heat and mass transfer has not been well improved, and the device is only suitable for sensible heat energy storage and cannot be used For hydrated salt thermochemical energy storage, the device has a large volume and low energy storage density

Embodiment 1
[0027] like Figure 1 to Figure 4As shown, a reactor for chemical energy storage of hydrated salts includes an adiabatic container 1, a column body 2 for wrapping hydrated salts, heat exchange tubes 3, fins 4, hydrated salts 5 and pipelines 6; The cross section of the container 1 is in the shape of a ring, and the center of the heat-insulated container 1 is provided with a column 2; the column 2 is cylindrical, and the center of the column 2 is provided with a heat exchange tube 3, and the column 2 is made of a foam metal plate The metal foam board has many fine-pore structures, which can prevent the hydrated salt 5 from slipping and allow the reaction steam to transfer effectively. The water vapor can conduct heat and mass transfer reactions with the hydrated salt in the radial and axial directions at the same time and can avoid the traditional Part of the hydrated salt in the stacked bed absorbs water and liquefies excessively, while the other part cannot fully absorb steam ...

The invention discloses a high-efficiency reactor for hydrated salt chemical energy storage. The high-efficiency reactor comprises a heat insulation container, a column body for wrapping hydrated salt, a heat exchange pipe, fins, hydrated salt and pipelines, wherein the column body is arranged in the heat insulation container; the heat exchange pipe is arranged at the center of the column body; the multiple fins are uniformly arranged between the heat exchange pipe and the column body; one end of each fin is connected with the outer wall of the heat exchange pipe, and the other end of the fin is connected with the inner wall of the column body; a space between the heat exchange pipe and the column body is filled with the hydrated salt; and the two pipelines are arranged on an upper end cover of the heat insulation container. The high-efficiency reactor for hydrated salt chemical energy storage disclosed by the invention can well enable reaction salt to react with steam; the reaction is faster and more thorough, and the heat transfer and mass transfer effect in a reaction process is obviously enhanced; irreversible loss caused by liquefaction of the hydrated salt due to excessive water absorption can be further effectively avoided, so that the number of times of recycling of an energy storage material is increased, and the service life of the material is prolonged; and meanwhile, the corrosion effect of the liquefied hydrated salt on the reactor is also avoided.
Description
technical field [0001] The invention relates to the technical field of thermochemical energy storage, in particular to a reactor for chemical energy storage of hydrated salts. Background technique [0002] Energy is the material basis of human activities, and the continuous development and utilization of energy has promoted the development of human civilization. As the energy crisis becomes more and more serious, human beings pay more and more attention to energy conservation and emission reduction. In order to use energy more rationally, it is necessary to store energy. Compared with sensible heat storage and latent heat storage, chemical heat storage has higher energy density and negligible heat loss, which can be used across seasons. Compared with other types of chemical heat storage methods, the decomposition reaction of hydrated salt has relatively lower operating requirements and costs, and the principle is simple. It is safe and feasible to use in actual projects, a...
