ていた。In addition, as a connecting material, that is, Tyrolide, which connects the intermediate wall forming the side cold insulation structure of the conventional double-shell low-temperature tank and the outer tank side plate via a spring, for example,
There is a device disclosed in No. 4 (Problem to be solved by the invention) The side cold insulation structure of the conventional double-shell cryogenic tank has a structure in which there is a space between the inner tank and the heat insulating material provided on the inner surface of the peripheral wall of the outer tank, or between the inner tank and the outer tank peripheral wall. By providing a space between the tank and the intermediate wall, we avoid poor deep cooling of the cold storage layer and stress loads on the inner tank of the cold storage layer caused by the settling phenomenon of granular cold storage material sedimentation and compaction caused by the loading and unloading of low-temperature storage liquid.

によって外槽を危険に落とし入れる恐れがあった。However, if the inner tank is damaged due to the same cause and the stored liquid leaks into the above space, the stored liquid will invade and damage the cold insulation layer, and the cold heat of the stored liquid will hit the outer tank and cause a drop in the temperature. There was a risk that the outer tank could be dropped into the tank due to JA fragility.

のである。In addition, the tie opening/first door that connects the middle wall of the conventional double-shell cryogenic tank and the side wall of the outer tank is formed to accommodate the head pressure of the cold insulation material and the expansion and contraction caused by the loading and unloading of the cold storage liquid. Therefore, in the event that the inner tank was damaged, there was a risk that the outflow liquid pressure and cold heat could damage the tie opening and the intermediate wall, and that the heat conduction and cold heat of the Tylolide could cause the outer tank to become embrittled at low temperatures. This invention was made in view of the above-mentioned problems, and the space between the intermediate wall that supports the cold insulation layer and the inner tank that stores the low 4 liquid is formed liquid-tight, and the space can be completely used. The side of the double-shell cryogenic tank serves as a storage space for the stored liquid that flows out when the inner tank breaks, and improves the safety of the double-shell cryogenic tank by completely blocking the cold heat from the stored liquid with a cold insulation layer. 5 (Means for solving the problem) The side cold insulation structure of the double shell low temperature tank according to the f series of this invention is as follows:
A thin corrugated plate with a convex and convex cross section is attached to the crosspieces of the frame body, and an intermediate wall is vertically installed in the space between the inner and outer tanks, and the lower end of the intermediate wall is
The cold insulation layer is elastically joined to the lower end cold insulation part of the elastic insulation material provided on the bottom plate of the outer tank, and is used to fill the space between the intermediate wall and the inner tank, and the cold insulation layer between the intermediate wall and the outer tank, which is filled with cryogenic material. This is the case where the structure is formed in a liquid-tight manner.

荷は低減される。In addition, the connecting material, that is, the tie rod, that supports between the outer tank filled with cold insulating material as a cold insulation layer and the intermediate wall is provided with a heat insulating part and a bent part, so that low temperature liquid can be transmitted from the inner tank or in the unlikely event of leakage. It is designed to block cold heat and absorb and support the pressure of low-temperature liquid that leaks out by the entire cold insulation layer. (Function) An intermediate wall in which a thin corrugated plate with an uneven cross section is attached to the cross section of the frame body. Ha, I! ! I$lI Yarigi, in other words, has a membrane structure, so it becomes a barrel body that is resistant to low-temperature embrittlement, and its uneven cross-sectional shape makes it resistant to loads from outside the tank caused by the cold insulation material, and furthermore, it is resistant to cold embrittlement. The shape is strong against loads from inside the tank caused by liquid flowing out from the inner tank. Furthermore, the flow force of the liquid flowing out from the inner tank is reduced by the resistance friction of the uneven cross section while moving in the space, and the mutual impact force of the liquid flowing out is reduced by the friction between the intermediate wall and the outer tank. The stress is relaxed with the aid of the cryogenic material, and the stress load on the outer tank is reduced.

維持する。Since the intermediate wall is supported by the lower end of the elastic heat insulating material provided on the bottom plate of the outer tank, in addition to the stress relaxation in the circumferential direction caused by the heat fluctuations due to the uneven cross section of the intermediate wall and the outflow liquid, It absorbs stress in both directions and maintains a liquid-tight state at all times.
万一の内槽破損による流出液は、液密にした中間壁と内
槽との間の空間に貯蔵保持できる。In the unlikely event that the inner tank is damaged, the liquid that flows out can be stored and retained in the space between the liquid-tight intermediate wall and the inner tank.

曲して保冷層全体で受圧する。The tie rod, which has a heat insulating part and a bent part to support the outer tank filled with cold insulating material to form a cold insulating layer, and the middle wall, has an Ur heating part that makes a big difference between the outside temperature from the outside and the cold temperature from the inside. At the bending part, it absorbs the thermal InI contraction force of the intermediate wall and cold insulation material,
Furthermore, in the unlikely event that the liquid pressure flows out from the inner tank, the tie rod itself bends and the entire cold insulation layer receives the pressure.

や保冷層を損傷することはない。(Effects of the Invention) As described above, this invention has the side part of the double-shelled low-temperature tank having a water-tight cold insulation structure, so it has the following effects.7 First, if the inner tank is damaged, The intermediate wall is resistant to low-temperature brittleness and fluid pressure support, and is blocked by an intermediate wall with a liquid-tight structure whose lower end is supported by pressure to have a packing effect.
The spilled storage liquid is safely stored within the intermediate wall and does not damage the outer tank or the cold layer.

上する。The space between the outer tank filled with ffl refrigerant and the intermediate wall is supported and fixed by a tie opening with a heat insulating part and a bent part, so the outer tank is insulated from cold heat and is protected from the inner tank in the event of an accident. The pressure of the effluent liquid is transmitted to the outer tank through the intermediate wall and the cold insulation layer, which reduces the stress, so the outer tank becomes a safer elliptical structure, and furthermore, the outer tank can be made into a simple horizontal structure. It also improves economic efficiency.

殻低温タンクとなる。In addition, if the side cold insulation structure according to the present invention is applied to a double-shell cryogenic tank having an outer tank made of prestressed concrete barrels capable of storing cryogenic liquid, in the unlikely event that the inner tank is damaged and the stored liquid Even if the liquid spills out, the liquid will be blocked by the intermediate wall and will be temporarily held and stored.Furthermore, even if the intermediate wall is destroyed for some reason, the liquid will be held and stored secondary in the outer tank, ensuring safety. This is a completely improved double shell low temperature tank.
