の上蓋である。1 and 2 show a heat storage device according to the present invention, FIG. 1 is a longitudinal sectional view, FIG. 2 is a sectional view taken along line A-A in FIG. 1, and FIG. It is a multi-tube heat storage device like the one above. In the drawing, reference numeral 15 denotes a heat storage tank, and an inner tank 18 containing a solid heat storage particle packed layer 17 is suspended from the lower surface of the upper wall 16 of the tank 15, and the upper end of the solid heat storage particle packed layer 17 and An upper steam space 19 is formed between the upper wall 16 of the heat storage tank 15 and a lower steam space 22 is formed between the bottom wall 20 of the inner tank 18 and the bottom wall 21 of the heat storage tank container 15. The space 19 is provided with steam connected to the side wall 25 through a hole 24 provided in the upper part of the side wall 23 of the inner tank 18 and a steam passage 26 formed by the side wall 25 of the heat storage tank 15 and the side wall 23 of the inner tank 18. It communicates with the conduction pipe 27. The lower steam space 22 communicates with a steam conduit 27 via a steam passage 26 . Reference numeral 28 denotes a steam dispersion tube through which steam as a reaction medium passes, and is disposed vertically within the solid heat storage particle packed bed 17, and its upper and lower portions are open to the upper steam space 19 and the lower steam space 22. 29 is a heat exchanger tube arranged in the solid heat storage particle packed bed 17, which gives heat to the solid heat storage particle packed bed 17 during a dehydration reaction (heat storage), and conversely takes away heat during a hydration reaction (heat radiation). . 3
0 is a heat exchange fluid distribution chamber provided above the upper wall 16 of the heat storage tank 15, and a partition plate 31 is provided inside. Heat exchange is performed between the particles in the particle packed bed 17. 33 is a heat exchange room 30
This is the top lid.
次に作用について説明する。 Next, the effect will be explained.

１７に滞留することはない。 The solid heat storage particles (hydrated salt) in the solid heat storage particle packed bed 17 heated by the heat transfer tubes 29 during the dehydration reaction (heat storage) process separate water as steam and become anhydrous salt, but the steam does not pass through the steam. Even if the water is cooled and condensed before reaching the pipe 27, it is discharged to the lower steam space 22 through the dispersion pipe 28 and does not remain in the solid heat storage particle packed bed 17.

間２２から分散管２８への蒸気の流入が妨げられ
た場合でも、上部蒸気空間１９から分散管２８へ
蒸気が流入することで主反応をスムーズに進行さ
せることが可能である。 Furthermore, during the hydration reaction (heat dissipation) process, even if the steam flowing from the evaporator is cooled and condensed in the heat storage tank and becomes water, it is discharged to the lower steam space 22. Through these heat storage and release processes (dehydration and hydration reactions), the problem that remains as a possibility with this proposed heat storage tank is that moisture tends to accumulate in the lower part of the solid heat storage particle packed layer 17 and polyhydrates are likely to be formed. That's true. As a result, even if the vapor dispersion tube 28 is clogged and the inflow of steam from the lower steam space 22 to the dispersion tube 28 is blocked, the main reaction can be achieved by allowing the vapor to flow from the upper steam space 19 into the dispersion tube 28. It is possible to proceed smoothly.

能である。 In the illustrated example, the heat exchange fluid dispersion chamber 30 is provided above the solid heat storage particle packed bed 17, but by providing it below, there is a risk that moisture may accumulate and form at the bottom of the solid heat storage particle packed bed 17. It is possible to prevent the formation of certain polyhydrates by heat from the heat exchange fluid.
また、図示例では蒸気分散管２８を管状とした
が、板状として固体蓄熱粒子充填層１７を分割設
置することも可能である。 Further, in the illustrated example, the steam dispersion pipe 28 is tubular, but it is also possible to have a plate shape and install the solid heat storage particle packed bed 17 in sections.

A solid heat storage particle packed bed can easily form a steam passage and a lower steam space partitioned by side walls and a bottom wall, and even if steam is cooled and condensed during hydration and dehydration reactions, the steam passage can be easily formed. Since the steam is led to the lower steam space from the steam dispersion tube, there is no problem with water caused by cooling and condensation of the steam, and even if hydrates are formed, the main reaction can proceed smoothly. .
