挙げられる。(Prior Art) Conventionally, as a heat storage method, there is a method of utilizing sensible heat using a solar water heater or night water heater type water as a heat storage medium, and these methods occupy the mainstream. The disadvantage of this type is that it requires a large amount of heat storage material and its container because the amount of heat storage per unit volume is low, and even if a good heat insulating material is used during heat retention, considerable energy is released for heat dissipation and long-term It is not suitable for storing heat.

ずるという問題点がある。When the reaction is a solid-gas reaction between a chemical heat storage material (powder) and a gas in an encapsulated or unitized device and the powder is carried out of the system together with a gas as a powder, and steam is used as a gas However, there is a problem that when the temperature decreases, the powder becomes clay-like and the solid-gas reaction is hindered. In addition, when the chemical heat storage material is wrapped or covered with cloth for encapsulation, etc. and is continuously recycled for use, the cloth etc. becomes clogged, and if the amount of filling the capsule etc. is too large, the accumulated heat storage material will weigh itself. Therefore, there is a problem in that the chemical heat storage material is solidified and the heat generation (endothermic) reaction rate is delayed due to these effects.

Moreover, it is desirable that the porosity is large. Its porosity is usually 30-85%, preferably 40-85

That is, when the heat storage device 12A is in the exothermic reaction state of the chemical heat storage material, the other heat storage device 12B is regenerated. That is, an exothermic reaction takes place in one of the heat storage devices and a regeneration takes place in the other heat storage device. For the regeneration, a heat supply device, for example, heat of exhaust gas is used. Regeneration of chemical heat storage materials can be combined with heat pumps for industrial-scale energy system plants (including application to district heating and cooling surrounding industrial groups), natural solar collectors, and exhaust gas. By removing the geographical and spatial barriers between various companies at different times such as summer and winter, day and night, or pressure,
It is carried out by combining each temperature condition.

A heat storage device characterized in that a heat supply device is connected to a reactor or a reaction tower filled with at least one heat storage capsule containing a powder chemical heat storage material at a ratio of 60% by volume. Since it is a capsule in which a powdery chemical heat storage material is filled in a cylindrical body of a heat-resistant porous body having a pore size of 1 to 10 μm, the fine chemical heat storage material should be powdered and discharged out of the system together with gas. The heat-resistant porous material does not become clogged and has the property of being able to withstand repeated reuse without solidifying itself. Furthermore, energy efficiency is improved from the perspective of energy saving, and a surplus heat source is captured and stored in a timely manner. Also, it can be used as a heat storage and heat generation device for a comprehensive energy complex that takes into consideration the time difference between day and night within each company or including the local community, the seasonal difference in winter and summer, and the arrangement of spaces.
