なる金属水素化物容器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal hydride container used in a heat storage device, and more specifically, the central hollow part of a donut-shaped heat pipe is filled with metal hydride, and the closing member that closes the openings at both ends thereof is equipped with an on-off valve. A hydrogen inlet/output conduit is provided, a partition is installed at the open end of the pipe through which hydrogen can pass but not the metal hydride, and an elastic heat insulating member is inserted between the partition and the metal hydride. Relating to hydride containers.

と、(ウ)反応の制御がガス流量制御だけで行えるの
で制御しやすいこと、(エ)単位体積当りの蓄熱量が
大きいことなどが挙げられる。 Heat storage technology using metal hydrides can store heat (for example, solar heat, factory waste heat, etc.) over long periods of time, and is attracting attention as a new heat storage method. The advantages of this method are (a) long-term heat storage is possible, (b) the reaction between metal and hydrogen is fast, (c) the reaction is easy to control because it can be controlled only by controlling the gas flow rate, and ( d) The amount of heat stored per unit volume is large.
一方欠点としては、(ア)金属水素化物は水素化脱
水素化を繰り返すと微粉化し、体積減少を起こす
ことと(イ)金属水素化物自体の熱伝導率が低いこと
から伝熱（反応熱の伝達）面で不利なことが挙げ

である。 On the other hand, the disadvantages are that (a) metal hydrides become pulverized when hydrodehydrogenation is repeated, causing volume reduction; and (b) metal hydrides themselves have low thermal conductivity, so heat transfer (reaction heat There are disadvantages in terms of communication. As a remedy for this drawback, it is advantageous to use the multi-tube heat exchanger method, which divides the metal hydride container as much as possible to increase the possibility of contact with the heat exchanger tubes even when volume decreases. The multi-tube heat exchange method described above is also advantageous for improving the drawback of (a).
It is also advantageous to mix silver, aluminum, etc.).
更に金属水素化物を用いる蓄熱装置は、金属水

さくするという点では満足すべきものではない。 Furthermore, heat storage devices using metal hydrides also have the disadvantage that the reaction heat of the metal hydride is lost as sensible heat to the container. Therefore, the above-mentioned shell-and-tube heat exchange method simply fills a pressure-resistant container with metal hydride and transfers the reaction heat directly (a heat exchanger such as a copper coil is placed inside the container, and the reaction heat is transferred using a heat medium such as water). (recovery method) or indirect method (method in which a heat transfer tube such as a heat pipe is inserted into the container in advance and the reaction heat is recovered via a heat exchanger installed at the other end of the heat pipe). This is not satisfactory in terms of reducing sensible heat loss.

ある。 The present invention was made in order to solve the above-mentioned drawbacks, and the central hollow part of a doughnut-shaped heat pipe is filled with metal hydride, and a hydrogen inlet/outlet conduit having an on-off valve is installed in the closing member. One open end is installed so as to open toward the central hollow part of the heat pipe, and the open end is closed with a partition body that allows hydrogen to pass through but does not allow metal hydride to pass through. The object of the present invention is to provide a metal hydride container in which an elastic heat insulating member is inserted between the compartment and the metal hydride.

一つの特徴とするものである。 As described above, the metal hydride container of the present invention closes the center opening at both ends of the donut-shaped heat pipe,
One feature of the heat pipe is that its central hollow portion is filled with a metal hydride, and the heat pipe itself is a metal hydride container.
その結果、従来の金属水素化物容器の様な耐圧

トパイプと金属水素化物の接触面積が大きいので
効果的な熱交換が可能であり、また金属水素化物
が水素の吸収、放出を繰り返して微粉化しても、
上記接触面積の減少はほとんどない。 As a result, there is less heat loss as sensible heat to the pressure container like conventional metal hydride containers, and the large contact area between the heat pipe and metal hydride allows for effective heat exchange. Even if the hydride repeatedly absorbs and releases hydrogen and becomes fine powder,
There is almost no decrease in the contact area.

かかることはない。 Furthermore, stress generated inside the metal hydride powder filled by pulverization can be absorbed by compression of the elastic heat insulating member, so that no large pressure is applied to the inner wall of the heat pipe due to the swelling phenomenon.

れ、その成形品非成形品のいずれも用いられる。 The elastic heat insulating member used in this invention is a porous and elastic heat insulating material that allows hydrogen to pass through but not metal hydride, and is sufficient for the maximum temperature inside the metal hydride container. It has heat resistance. For example, ceramic wool whose main components are SiO 2 and Al 2 O 3 (Kao Wool, Isolite Industries (registered trademark); Ibi Wool, Kasuhikawa Electric Industries (registered trademark), etc.), glass wool, etc. Both can be used.

-B is a cross-sectional view. 1 and 2 indicate the outer and inner tubes of the donut-shaped heat pipe, respectively, and 3 indicates the wick. The openings at both ends of this doughnut-shaped heat pipe are closed by closing plates 4 and 5, and a hydrogen inlet/output conduit 8 having an on-off valve 7 is attached to the closing plate 4. Furthermore, the hydrogen inlet/outlet conduit 8 is attached to the closing plate 4. A porous conduit 9 with a bottom, made of a sintered alloy, etc., extends coaxially from the central hollow part of the heat pipe through which hydrogen can pass, but metal hydrides cannot pass through. . Furthermore, the porous conduit 9 is covered with an elastic heat insulating member 10 that allows hydrogen to pass through but not metal hydrides, such as ceramic wool (Kao Wool, a registered trademark of Isolite Kogyo Co., Ltd.). 10 is covered with a wire mesh 11 made of stainless steel or the like that does not react with hydrogen or hydrogenated metals. Moldings 12 and 13 of the same elastic heat insulating material are also tightly attached to the inner surfaces of the closing members 4 and 5. The central hollow portion is filled with metal hydride 6.

１３を有しないものも含まれる。 In this metal hydride container, the heat pipe itself is a container, so there is less heat loss as sensible heat, and the contact area between the heat pipe and the metal hydride is large, so effective heat exchange is possible. Even if the hydride is pulverized by repeatedly absorbing and desorbing hydrogen, the above-mentioned contact area hardly decreases. Furthermore, it prevents sensible heat loss to the heat insulating members 10 and 12, the porous conduit 9, and the closing plates 4 and 5, and also acts as a buffer against volume changes when metal hydride is repeatedly absorbed and released. . In other words, when the metal hydride repeatedly absorbs and dissociates hydrogen and becomes fine and its volume decreases, it acts to press the metal hydride powder against the inner wall of the heat pipe, reducing the contact area between the heat pipe and the metal hydride powder. It suppresses the drop and continues to maintain good heat exchange function. Furthermore, if stress is generated inside the metal hydride due to its pulverization, the elastic heat insulating members 10, 12, and 13 will be compressed and absorb the force, resulting in large pressure on the inner wall of the heat pipe, etc. This is prevented, and the metal hydride's ability to absorb and dissociate hydrogen is maintained. The heat storage container of the present invention also includes one having the above-mentioned embodiment but not having the elastic heat insulating members 12 and 13.

By heating, the metal hydride in the metal hydride containers 41a, 41b, and 41c is heated and dehydrogenated. The generated hydrogen gas on-off valves 46a, 46b, 46c, 4
6d, 56a, 56b, 56c are opened to open the metal hydride containers 51a, 51b, 51c of hydrogen storage section B.
It reacts with the metal filled inside to form a metal hydride and stores hydrogen. Next, when it is desired to utilize the stored heat, a low-temperature heat medium that has collected waste heat is introduced into the heat exchanger 54 from the heat medium inlet 59b, and the heat is used to transfer the heat exchange part 60 of the metal hydride container.
The on-off valves 57a, 57b, 57c, 46 are heated to dehydrogenate the metal hydride in the metal hydride containers 51a, 51b, 51c by heating the metal hydride containers 51a, 60b, 60c, and open the generated hydrogen.
a, 46b, 46c, 46d to the metal hydride containers 41a, 41b, 41c of the heat storage section A , and the heat generated by reacting with the metal inside is transferred to the heat medium through the heat exchange sections 50a, 50b, 50c of the metal hydride container. This heat medium is used for purposes such as air conditioning and hot water supply.
