。The present invention aims to solve the problem by utilizing the characteristics shown by the isothermal dissociation pressure curve of the hydrogen storage alloy shown in FIG. The relationship between hydrogen concentration and pressure at the high temperature 1111Tt and at the low temperature T2 is represented by two curves shown in FIG. Consider hydrogen release. Assume that equilibrium has now been reached at point A of the alloy temperature TI. Let this equilibrium pressure be pe. At temperature T2, the pressure at the same hydrogen release is P. These differences Δ

The equilibrium dissociation pressure decreases to point B along the equilibrium dissociation pressure curve in the figure. Alternatively, the alloy temperature decreases due to heat absorption accompanying hydrogen release, and the pressure decreases to the 0 point in FIG. 3.
一般に水素吸蔵合金は伝熱が悪く、熱媒によってＴ２を

容器１．２は水素配管７によって接続されている。A high temperature heat source 3 and a heat medium transport pipe 5 are connected to the discharge side alloy container l. The heat medium is supplied from the high temperature heat source 3 to the heat medium transport pipe 5 and exchanges heat with the alloy in the release alloy container 1 . A low-temperature heat source 4 is connected to the storage-side alloy container 2 through a heat medium transport pipe 6. The heat medium is supplied from the low-temperature heat source 4 to the heat medium transport pipe 6, and exchanges heat with the alloy in the storage-side alloy container 2.

出力は吸蔵側の調節弁ｌＯに接続されている。In the hydrogen pipe 7, there are control valves 9. Pressure gauge 11. Hydrogen turbine 8, pressure gauge 12. A control valve 10 is attached. In addition, the output of the pressure gauge 11 located on the discharge side of the hydrogen turbine 8 is connected to the controller 13, and the output of the controller 13 is also connected to the pressure gauge 11 on the discharge side, which is connected to the control valve 9 on the discharge side. @Kun 17 question Shohi
The output of +l2 is connected to the controller 14, and the output of the controller 14 is connected to the storage side control valve lO.

定に保たれる。またタービン出側圧力は調節計１４と調
節弁１０によってタービン入側圧力の設定値よりも低い
一定の圧力に保たれる。The turbine inlet pressure is kept constant by a regulator 13 and a control valve 9. Further, the turbine outlet pressure is maintained at a constant pressure lower than the set value of the turbine inlet pressure by the regulator 14 and the control valve 10.
このとき放出側の合金の平衡圧力は、高温熱媒の温度に
おいてタービン入側圧力よりも高く、また吸蔵側の合金
の平衡圧力は低温熱媒の温度において、タービン出側圧
力よりも低くなるように１合金および熱媒の温度を設定
する必要がある。At this time, the equilibrium pressure of the alloy on the discharge side is higher than the pressure on the turbine inlet side at the temperature of the high temperature heating medium, and the equilibrium pressure of the alloy on the storage side is lower than the pressure on the turbine outlet side at the temperature of the low temperature heating medium. It is necessary to set the temperature of the alloy and heating medium to 1.
合金容器内の合金平衡圧力は、水素の放出、吸蔵に伴い
低下あるいは上昇する。また、外的要因として熱媒の温
度変化によっても変化する。The alloy equilibrium pressure within the alloy container decreases or increases as hydrogen is released or absorbed. It also changes due to changes in the temperature of the heating medium as an external factor.

出側圧力が一定であればタービン入側圧力は減少する。When the equilibrium pressure of the release-side alloy decreases, the difference ΔP between the equilibrium pressure Pe and the pressure P around the alloy decreases, and the hydrogen release reaction rate decreases. Therefore, the speed of hydrogen transfer from the discharge-side alloy container 1 to the storage-side alloy container 2 becomes small. If the turbine outlet pressure is constant, the turbine inlet pressure will decrease.
このような圧力および流量の変化に対し本発明では次の
ように対処し、圧力および流量を一定に保つ。The present invention deals with such changes in pressure and flow rate as follows to keep the pressure and flow rate constant.

は一定に保たれる。That is, a decrease in the turbine inlet pressure is detected by the pressure gauge 11, this is input to the controller 13, and the regulating valve 9 is operated in the opening direction. When a flow meter is used on the discharge side and the flow rate is feedback-controlled by a control valve, this decrease in flow rate is detected by the flow meter 15 and inputted to the controller 13, which causes the control valve 9 to move in the opening direction. let When the control valve 9 moves in the opening direction, the pressure inside the discharge side alloy container decreases, so
The difference ΔP from the equilibrium pressure of the alloy becomes large (becomes large), and the hydrogen release rate increases. As a result, the hydrogen flow rate increases and the turbine inlet pressure also recovers. The equilibrium pressure of the alloy on the release side rises, and the flow rate increases. In this case, the control valve 9 operates in the closing direction, and the pressure and flow rate are kept constant.
一方、吸蔵側の合金平衡圧力が上昇するとΔＰは小さ（
なり、水素吸蔵反応速度は小さくなる。On the other hand, when the alloy equilibrium pressure on the storage side increases, ΔP becomes small (
Therefore, the hydrogen storage reaction rate decreases.
水素流量は小さくなり、タービン入側圧力が一定ならば
タービン出側圧力は上昇する。The hydrogen flow rate becomes smaller, and if the turbine inlet pressure is constant, the turbine outlet pressure increases.

辺の圧力は上昇しΔＰは大きくなり流量が大きくなる。The pressure gauge 12 detects this change, and the output is sent to the controller 14.
The receiver operates the control valve 10 in the opening direction. When a flow meter is used on the storage side and feedback control is performed using the flow rate and a control valve, this decrease in flow rate is detected by the flow meter 15,
This is input to the controller 14, and the control valve IO is operated in the opening direction. When the control valve lO operates in the opening direction, the pressure around the storage side alloy increases, ΔP increases, and the flow rate increases.
この結果タービン出側圧力も低下して流置、圧力は一定
に保たれる。As a result, the turbine outlet pressure also decreases and the pressure is kept constant.
吸蔵側合金の平衡圧力が低下し、流量が増加した場合に

は一定に保たれる。When the equilibrium pressure of the storage-side alloy decreases and the flow rate increases, the control valve lO operates in the closing direction, and the turbine outlet pressure and flow rate are kept constant.
以上のようにフィードバック制御によりタービン前後圧
力が一定に保たれればタービンを通過する水素量も一定
となり安定したタービンの運転が可能となる。As described above, if the pressure before and after the turbine is kept constant by feedback control, the amount of hydrogen passing through the turbine will also be constant, allowing stable operation of the turbine.

However, the pressure and flow rate before and after the turbine can be kept constant.
