【考案の詳細な説明】
本考案は低温液化ガス貯蔵設備等における発生
ガスの再液化装置に関する。[Detailed Description of the Invention] The present invention relates to a reliquefaction device for generated gas in low-temperature liquefied gas storage facilities and the like.
低温液化ガス貯蔵設備においては従来低温液化
ガスの常温出荷と発生ガスの再液化の同時性がな
いために出荷用液体のもつ冷熱を発生ガスの再液
化に有効利用することができなかつた。 Conventionally, in low-temperature liquefied gas storage equipment, the cold energy of the shipping liquid cannot be effectively used for re-liquefying the generated gas because the shipping of the low-temperature liquefied gas at room temperature and the re-liquefaction of the generated gas have not been carried out simultaneously.
本考案は、こうした事情に鑑みてなしたもの
で、低温液化ガスの常温出荷時における冷熱を簡

る。 A shipping line 7 connected to the low temperature storage tank 5 via a shipping pump 6 is guided to the shipping side via a heat transfer pipe 8 disposed through the container 1, and is connected to the inlet and outlet of the container 1 of the shipping line 7. Switching valve 9,1 in side position
Set 0. Further, a generated gas line 11 for extracting generated gas connected to the upper part of the low temperature storage tank 5 is connected to the heat transfer tube 8 through a compressor 12 and a switching valve 13.
A reliquefied gas return line 1 connected to the other end side (output side of the shipping line) and connected to one end side (inlet side of the shipping line) of the heat transfer tube 8 via a switching valve 14.
5 is connected to the tank 5 via a header 16 and a return pump 17. Further, a flow path 19 through which a room temperature medium such as seawater flows is connected to a heat transfer pipe 18 disposed through the container 2 to constitute a reliquefaction device for generated gas.

切換弁（流量調節付）である。 Further, a shipping bypass line 21 is provided in which a part of the low temperature fluid in the shipping line 7 from the shipping pump 6 passes through a heat exchanger 20 and joins the shipping line 7 after leaving the container 1, Further, a generated gas bypass line 22 is provided which connects the generated gas line 11 and the header 16 via the heat exchanger 20, thereby making it possible to reliquefy the generated gas at the time of shipping the low temperature fluid. 23 in the figure,
24 is a switching valve (with flow rate adjustment) provided in each of the bypass lines 21 and 22.

荷時の冷熱が貯蔵される。 In the above, when the switching valves 9 and 10 are opened to ship the low-temperature liquefied gas, the inside of the container 1 is cooled through the heat transfer pipe 8, and the metal hydride A is absorbed while the heat generated by the production is absorbed. The production reaction progresses. At this time, by passing a room temperature fluid such as seawater through the room temperature medium flow path 19, the inside of the container 2 is heated through the heat transfer pipe 18, thereby promoting the decomposition reaction of the metal hydride B. Hydrogen gas generated in the container 2 flows to the container 1 side via the hydrogen gas flow path 4 and is subjected to the reaction for producing the metal hydride A. Thereby, the cold energy during shipping of the low-temperature liquefied gas is stored.

にする。 According to the above device, by reducing the number of heat transfer channels 8 provided in the container 1, it is possible to reduce the loss of cold storage heat required at the time of starting the refrigeration operation. On the other hand, in the above-mentioned apparatus, it is not possible to simultaneously store cold fluid during shipment of the low-temperature fluid and reliquefy the generated gas in the container 1. Therefore, if such a need exists, separate bypass lines 21, 22 and heat exchanger 20 allow simultaneous operation by directly reliquefying the generated gas with the cold shipping fluid.
