従来の構成例を第２図に示す。 Metal hydrides, such as TiMn alloys, absorb hydrogen gas and perform an exothermic reaction under certain temperature and pressure conditions, and release hydrogen gas and perform an endothermic reaction under other temperature and pressure conditions. . Utilizing the above-mentioned properties of metal hydrides, the reaction heat when metal hydrides react with hydrogen is extracted to the outside by heat exchange with an appropriate heating medium, and when hot heat is generated, it is used for heating and hot water supply, and cold heat is generated. Sometimes it can be used for cooling purposes. FIG. 2 shows an example of a conventional configuration of an intermittent-operating heat pump device that uses high-temperature factory waste gas as a driving heat source.

構成されている。 Metal hydride 1 (referred to as MH 1 ) and metal hydride 2 with two different hydrogen storage equilibrium pressures
(MH 2 ) is filled in the metal hydride containers 3 and 4 as shown in FIG. 2, and in particular, the metal hydride container 3 is divided into a plurality of tubular containers. Metal hydrides 1 and 2 are in hydrogen conduit 5
A valve 6 is provided in the middle of the conduit 5. The metal hydride storage container 3, which is divided into a plurality of parts, is installed in a high-temperature gas passage 7 and is heated by a high-temperature gas 8. A heat medium flow path 9 is provided in the metal hydride storage container 4.
is provided so that the reaction heat generated when the metal hydride absorbs and dissociates hydrogen is transferred to the heat medium through heat exchange.

器３にMH1を等分に充てんしても、加熱温度の
不均一性により水素移動量が異なり、合金の利用
度に差が生じて温度の低い部分のMH1は利用度
が悪いという欠点があつた。 Now, consider the case of transferring hydrogen from MH 1 to MH 2 . Before the start of hydrogen transfer, MH 1 is in a state where it stores more hydrogen than MH 2 . MH 1 is heated to a high temperature by high temperature gas 8, and the hydrogen equilibrium pressure is on one side.
When the temperature becomes higher than MH 2 and valve 6 is opened, hydrogen moves from MH 1 to MH 2 . At this time,
Since MH 2 absorbs hydrogen, it causes an exothermic reaction and the generated heat is extracted to the outside by a heat medium. Here, when the metal hydride storage container 3 is heated by the high temperature gas 8, the first row closest to the high temperature gas 8 is heated.
The temperature of MH 1 is the highest, and according to the flow direction of high temperature gas 8, the temperature of high temperature gas 8 decreases due to heat exchange with MH 1 , and the flow rate of high temperature gas decreases due to the decrease in temperature, so the heat transfer coefficient decreases. As the temperature decreases, the temperature at which MH 1 is heated becomes lower as one goes to the back row. In this way, when the temperature of MH 1 is not uniform and has a temperature distribution, the hydrogen dissociation equilibrium pressure also varies in height, and when the valve 6 is opened, MH 1
When hydrogen is transferred from MH 2 to MH 2, hydrogen transfer occurs due to pressure difference, so the amount of hydrogen transferred from MH 1 is largest in the area where the hydrogen dissociation equilibrium pressure is high (the area where the temperature is high), and the hydrogen dissociation equilibrium pressure The amount of hydrogen transferred from MH 1 is the lowest in the low temperature area (low temperature area). In other words, even if the divided metal hydride storage container 3 is filled with MH 1 in equal parts, the amount of hydrogen transferred will differ due to the non-uniformity of the heating temperature, resulting in a difference in the degree of utilization of the alloy, resulting in lower temperature parts. MH 1 had the disadvantage of being poorly utilized.
この欠点は他の作動物質、例えばゼオライトに
おいても同様である。 This drawback also applies to other working materials, such as zeolites.
発明が解決しようとする問題点

気体としての利用度が悪くなるという欠点があつ
た。Problems to be Solved by the Invention As described above, when a plurality of divided working substance containers are heated with high-temperature gas, a temperature distribution occurs between the working substance containers. The dissociation equilibrium pressure of the working substance in the lower temperature area with respect to the working gas is lower, and when the working gas is transferred to the other paired container, the amount of working gas transferred is smaller than that of the working gas in the higher temperature area. This has the disadvantage that the amount of gas decreases, making it less useful as a working gas.

ことにより解決しようとするものである。Means for Solving the Problems As described above, the present invention allows a plurality of containers containing a working substance or a working gas to communicate with each other so that the working gas is mutually transferred so that the working substance reacts with the working gas. At least one of the working substance storage containers of an intermittent-operating heat pump device that uses the reaction heat from the reaction for heating, hot water supply, or cooling is divided into multiple containers, installed in a high-temperature gas passage, and heated by the high-temperature gas. When releasing the working gas, by making the arrangement of the working substance storage containers non-uniform, for example, by shifting from a zigzag arrangement to a staggered arrangement according to the flow direction of the hot gas. This is what we are trying to solve.

移行している。 The metal hydride 1 (MH 1 ) is filled into a plurality of divided tubular metal hydride storage containers 3 in equal amounts. A metal hydride storage container 4 is filled with metal hydride 2 (MH 2 ). Piping for hydrogen gas to flow in and out is connected to each end of the tubular metal hydride storage container 3, and these pipes are assembled to finally form one hydrogen conduit 5. The metal hydride container 4 communicates with the metal hydride container 3 via a hydrogen conduit 5 . A valve 6 is provided in the middle of the hydrogen conduit 5. A large number of tubular metal hydride storage containers 3 are
It is installed in the high temperature gas passage 7 and is configured to be heated by the high temperature gas 8. The arrangement of the metal hydride containers 3 continuously changes from a diagonal arrangement to a staggered arrangement according to the direction in which the high-temperature gas flows.

利用しようとする場合を考える。 In the intermittent operation heat pump device having the above configuration, hydrogen is transferred from metal hydride 1 (MH 1 ) to metal hydride 2 (MH 2 ), and the reaction heat when MH 2 absorbs hydrogen is transferred to the heat medium flow path 9. Consider the case where the heat is transferred to a heat medium inside and taken out to be used for space heating or hot water supply.

されることになる。 In order to release hydrogen from metal hydride 1,
The metal hydride storage container 3, which is divided into many parts, is heated by the high-temperature gas 8, but the portion of the metal hydride storage container 3 on the inflow side of the high-temperature gas 8 is heated because the containers in the rear row are in the shadow of the containers in the front row. The gas-side heat transfer coefficient is poor in the grid arrangement, and although the temperature of the high-temperature gas 8 is high, the temperature of the metal hydride 1 does not rise much. However, as the high-temperature gas moves toward the outflow side, the storage containers 3 are arranged in a staggered manner, and the heat transfer coefficient on the gas side increases. The temperature of the metal hydride 1 does not change from that up to the front row, and the temperature of the metal hydride 1 is uniformly heated as a whole.
従つてバルブ６を開けて水素ガスを金属水素化
物２へ向かつて放出させる場合、多数に分割され
た金属水素化物１の温度が均一であるため水素平
衡圧力も均一となり、全ての分割された金属水素
化物収容容器３からほぼ等量ずつの水素が放出さ

利用することができるのである。 Therefore, when the valve 6 is opened to release hydrogen gas toward the metal hydride 2, the temperature of the metal hydride 1 divided into many parts is uniform, so the hydrogen equilibrium pressure is also uniform, and all the divided metal hydrides are Almost equal amounts of hydrogen are released from the hydride storage container 3. In other words, it is possible to uniformly utilize the hydrogen storage and release ability of the metal hydride 1 filled inside each divided element of the divided metal hydride storage container 3.
