は省略することができる。An embodiment of the present invention will be described below with reference to FIG. A reactor 1 containing a reaction material (solid such as zeolite or quick lime, liquid such as calcium chloride aqueous solution) 4 and a reaction target material (water,
The evaporator 2 accommodating (alcohol, etc.) 5 is connected by pipes 11, 13 and 14 as shown in the drawing, and a valve 17 is provided between these pipes. Further, a heat exchanger 9 is provided in the container 3 accommodating the liquid (water, etc.) 6, and a pipe 11- attached to one end of the heat converter 9
a is connected to a part of the pipe 11 via a valve 16. A pipe 12 attached to the other end of the heat exchanger 9 is connected to a part of the evaporator 2 as shown in the figure. During the heat storage operation (regeneration operation), a high-temperature heat medium (using solar heat or waste heat) is flowed through the heat exchanger 7 provided in the reaction material 4 and contained in the reaction material 4. The reacted material is heated and separated. A heater may be used instead of the heat exchanger 7, or both may be used in combination. The vapor of the reacted material generated by this is the pipe 11, the pipe 11-a,
It passes through the valve 16 and enters the heat exchanger 9, where the heat of condensation is released and liquefied. This heat is transferred from the heat exchanger 9 to the liquid 6 around it, and the temperature of the liquid 6 rises. That is, the heat applied to regenerate the reaction material 4 is
The liquid 6 in the container 3 accumulates heat and is collected. On the other hand, the liquid of the reaction target material 5 condensed in the heat exchanger 9 is returned to the inside of the evaporator 2 through the pipe 12. At the time of such heat storage operation, depending on the time and the case, the valve 17 is opened and the vapor of the reaction target material separated from the reaction material is directly passed through the pipe 11, the valve 17, the pipe 13 and the pipe 14 to the inside of the evaporator 5. It can also be introduced and condensed there. In such a case, the evaporator acts as a condenser, and if a low-temperature heat medium is caused to flow in the heat exchanger 8 in the evaporator, it has such an effect. The liquid (hot water) 6 heated in the container 3 can be appropriately taken out to the outside and used. The pipe 32 and the valve 33 attached to the container 3 are for water supply (or hot water supply), and the pipe 30 and the valve 31 are for hot water supply (or water supply). On the other hand, the heat radiation operation is performed as follows. First, the valves 16 and 17 are closed. Next, the reaction target material 5 in the evaporator 2 is heated to a predetermined temperature. As this method, a heat medium is flown into the heat exchanger 8 provided in the reacted material 5 (utilizing solar heat or waste heat) to heat it. Alternatively, a heater 10 is provided in the reaction target material 5 and heated by energizing. These two methods may be used in combination. When the reacted material 5 has reached a predetermined temperature, the valve 17 is opened to allow the vapor of the reacted material 5 to flow through the pipes 14 and 1.
It is introduced into 4 parts of the reaction material in the reaction container 1 via 3, 11. As a result, the reaction material 4 is heated to a high temperature, but it is also possible to take out hot water or steam having a remarkably high temperature without flowing a heat medium (water or the like) into the heat exchanger 7. At the time of this heat radiation operation, the internal pressure in the evaporator 2 rises, and the reacted material 5 inside may flow back through the pipe 12 and enter the heat exchanger 9, but in order to prevent this inconvenience ,
A check valve 15 may be provided in a part of the pipe 12. The present heat storage device alternately performs the heat storage operation and the heat radiation operation, and in this process, two hot waters having different temperatures or hot water and steam can be obtained and can be taken out at the same time. Further, in this example, the pipe 18 having the valve 21 at the pipe 11-a part, the pipe 19 having the valve 22 at the pipe 14 part, and the pipe 2 having the valve 23 at the reactor 1 part.
Although 0 is provided, it is used to evacuate the inside, or to inject the reaction target material 5 into the inside. The pipe and the valve can be omitted as long as the reaction material 4 and the reaction target material 5 are once put in the inside so that the gas is not generated from the inside or the gas is not invaded from the outside.

には冷水などの熱媒体が流される。FIG. 2 shows another embodiment. This is a pipe 12 provided with a cooler 24 having a heat exchanger 25. This is because when the temperature of the liquid 6 in the container 3 rises and the heat exchanger 9 alone cannot completely condense the vapor of the reaction target material 5 that enters the inside during regeneration, the heat exchanger 9 It is used as an aid. A heat medium such as cold water is flowed in the heat exchanger 25.

In this case, the pipe 11-a at the inlet of the heat exchanger 9 and the pipe 12 at the outlet are connected by a pipe 26 having a valve 27 as shown in the figure. By closing the valve 16 and opening the valve 27, the vapor of the material 5 to be reacted generated in the reactor 1 is directly introduced into the cooler 24 part through the valve 27, the pipe 26 and the pipe 12. It can also be condensed.

This is a structure in which the lower part of the evaporator 2 or a pipe 12 connected to it and the reactor 1 are connected by a pipe 28 having a valve 29 as shown in the drawing.

It was made to react with and to have fast heating property.
