[0027] [insulated container]

[0028] First, a first embodiment of the present invention will be described.

[0029] In the present embodiment, as a representative example of a thermally insulated container, that is, a thermally insulated container that is used in an environment that may be exposed to liquid water and holds a substance at a temperature lower than normal temperature, the following examples are listed: Figure 1A The illustrated spherical tank 101 for LNG installed in the LNG carrier 100A will be described as an example.

[0030] In addition, in this embodiment, a case is described in which the substance held at a temperature lower than normal temperature is fluid LNG, but the present invention is not limited to this example, and may be solid, for example.

[0031] Such as Figure 1A As shown, the LNG carrier 100A of the present embodiment is a ship of a spherical independent tank type, and has a plurality of spherical tanks 101 ( Figure 1A 5 in total).

[0096] Next, a second embodiment of the present invention will be described.

[0097] In the first embodiment, as a representative example of the heat insulating container, Figure 1A with Figure 1B The spherical tank 101 which the shown LNG carrier 100A has. However, the present invention is not limited thereto, and in the second embodiment, such as Figure 3A with Figure 3B As shown, the case of the LNG inboard tank 110 included in the diaphragm type LNG carrier 100B will be described.

[0098] Such as Figure 3A As shown, the LNG carrier 100B of the present embodiment is a ship of the diaphragm type, and has a plurality of inboard tanks 110 ( Figure 3A 4 in total). A plurality of inboard boxes 110 are arranged in a row along the longitudinal direction of the hull 111 . Each inboard box 110 such as Figure 3B As shown, the interior becomes an internal space (substance holding unit) for storing (holding) LNG. In addition, most of the inboard box 110 is supported by...

no. 3 approach

[0107] Next, a third embodiment of the present invention will be described.

[0108] The heat insulating container of the first embodiment or the second embodiment is the spherical tank 101 installed in the LNG carrier 100A or the inboard tank 110 installed in the LNG carrier 100B. However, the heat insulation container of this invention is not limited to this, For example, it may be the LNG tank installed in land. In the third embodiment, refer to Figure 4 with Figure 5 Such an LNG tank will be described.

[0109] Figure 4 An above-ground LNG tank 120 is shown in the figure. This ground-type LNG tank 120 has a spherical tank body 124 as a tank body similar to the spherical tank 101 of the first embodiment, and the tank body 124 is supported on the ground surface 50 by a support structure 121 . The support structure part 121 is comprised from the several support|pillar 122 provided in the vertical direction on the floor 50, and the bracket 123 provided between the supp...

Abstract

A heat-insulating container that can be used in an environment wherein the container can be exposed to liquid moisture, the container being provided with: a container main body that has on the inside thereof a substance holding part that holds a substance at a temperature that is below ordinary temperature; and a heat-insulating structure that is provided to the container main body and that uses at least a vacuum heat-insulating material. The vacuum heat-insulating material (10) has an outer covering material (11) and an internal member that is enclosed in the outer covering material (11) in a decompressed and sealed state. The internal member is configured from a material that does not generated hydrogen when liquid moisture has come into contact therewith.

Description

technical field [0001] The present invention relates to a heat insulating container having a vacuum heat insulating material, storing therein a low-temperature substance below normal temperature, a vacuum heat insulating material used in the heat insulating container, and a ship having the heat insulating container. Background technique [0002] Flammable gases such as natural gas and hydrogen are gases at room temperature. Therefore, when it is stored or transported, it is liquefied and kept in an insulated container. Natural gas is used as an example of combustible gas, and typical examples of heat-insulated containers for holding liquefied natural gas (LNG) include LNG storage tanks installed on land, tanks of LNG carriers, and the like. LNG is a low-temperature substance with a temperature lower than normal temperature by 100°C or more (the temperature of LNG is usually -162°C). Therefore, in these LNG tanks, it is required to store low-temperature substances below nor...
