[Detailed description of the invention]

[0001]

[Industrial applications] The present invention relates to a nuclear power plant,
The present invention relates to a heat insulating device for a tank provided in a petrochemical plant, a food chemical plant, or the like, and particularly to an improvement in a heat insulating device for a tank suitable for a vertical tower tank.

[0002]

2. Description of the Related Art Conventionally, a heat insulating structure shown in FIGS. 5 and 6 has been known as a heat insulating device for a vertical tower tank (mainly a device for keeping heat).

In FIGS. 5 and 6, 1 is a tank wall, 2 is a supporting member such as a lightweight steel frame fixed to the outer peripheral surface of the tank wall, 3 is a molded heat insulating material, 4 is a binding material such as a wire,
Reference numeral 5 denotes a metal armor plate for protecting the heat insulating material, and 6 denotes an armor plate mounting screw.

In the construction of the heat insulating structure, first, the heat insulating material 3
Is supported by the support member 2 and fixed with the binding material 4, and then the goose-folded exterior plate 5 is assembled on the surface of the heat insulating material 3 and fixed with screws 6. In the mirror portion such as the top of the tank, The heat insulating material is cut into a fan shape by being combined with the actual material, and is supported by the support member 2, fixed with the binding material 4 as described above, the outer plate 5 is assembled, and fixed with screws.

[0005]

In the heat insulating structure having the above-mentioned structure, a large amount of dust is generated because the fibrous heat insulating material or the powder heat insulating material is attached in a bare state or cut at the site. In addition, when a part of the heat insulating material is removed during the periodic inspection of the tank, the heat insulating material cannot be easily removed, so that dust is generated. The generation of such dust is extremely harmful in nuclear power plants and food chemical plants. Some of the removed members cannot be reused. Further, when the tank equipment is renewed due to the aging of the plant, there is a problem that a large amount of industrial waste is generated. In addition, since special skills such as sheet metal processing are required as in the case of an exterior plate, it is difficult to secure human resources, and there is a problem that construction work is delayed.

[0006]

[Purpose of the invention] The present invention is capable of attaching and detaching a heat insulating material in a short time, and generating very little dust.
It is another object of the present invention to provide an improved tank heat insulating device that can be reused.

[0007]

According to the present invention, there is provided a heat insulating device for a tank, comprising: a support member comprising an inner ring and an outer ring capable of holding a tank wall detachably in a circumferential direction thereof and fixing the tank wall to a tank side; A heat insulating material with an outer skin positioned between the inner and outer wheels of the member and detachably supported on the support member via a locking device, and provided on the surface of the heat insulating material with the outer skin, and And an exterior plate which can be detachably supported and can be connected to each other by another locking tool.

[0008]

In the tank heat insulating device having the above structure, the support member, the heat insulating material with the outer cover, and the outer plate are all unitized.
Because it is prefabricated, it can be easily attached and detached and reused. In addition, since the heat insulating material uses a heat insulating material with a skin, the generation of dust is extremely small.

[0009]

1 to 4 show an embodiment of the present invention. In the figure, 1 is a tank wall, and 10 is a support member provided on the outer periphery of the tank wall. The support member 10 is composed of an inner ring 10a abutting on the tank wall surface, a concentric outer ring 10b spaced at a predetermined distance from the inner ring 10a, and a connecting plate 10c connecting the two rings. It is divided into segments, and is configured to have a ring shape with the screw 10d.

Reference numeral 11 denotes a heat insulating material, which is an inorganic fiber material 11a.
Is covered with a bag-shaped outer cover 11b made of a heat-resistant fiber. The heat insulating material with outer skin 11 is positioned between the inner and outer rings 10a and 10b of the support member 10, and is fixed to the inner ring 10a by a locking tool including a hook 12 provided on the inner ring 10a and a ring 13 provided on the upper side of the heat insulating material. It can be detachably supported. The outer ring 10b may be provided with a hook 12 so that the heat insulating material 11 is supported by the inner ring 10a and the outer ring 10b. In addition, on both the left and right sides of the heat insulating material 11 with a skin,
There is provided a fastener made of a hook-and-loop fastener 14 called a heat-resistant chuck or a magic tape capable of detachably connecting the heat insulating materials with the outer cover to each other. Reference numeral 15 denotes a metal exterior plate. The exterior plate 15 can be detachably supported on the outer ring 10b of the support member 10 by a locking tool including clips 16 provided at both upper and lower edge portions thereof. Further, on both left and right sides of the exterior plate 15, there are provided locking members capable of detachably connecting the exterior plates with the buckle 17.

In the heat insulating apparatus having the above structure, the support member 10 is held and fixed in the tank wall 1, and the heat insulating material 11 with the outer skin is provided between the inner and outer rings 10a and 10b constituting the support member 10. The hooking ring 13 is hooked on the hook 12 on the inner ring 10a side, and the heat insulating material with the outer skin is joined to the outer ring 10b by the hook-and-loop fastener 14. Then, the outer plate 15 is pulled to the outer ring 10b by the clip 16 thereof. The heat insulation structure is completed by hanging and supporting and connecting the exterior plates with the buckle 17. In addition, the said heat insulation structure can be easily disassembled by removing each member mentioned above sequentially in reverse to the time of assembly.

[0012]

[Effects of the Invention] As described above, the following effects can be obtained by applying the present invention. (1) All members constituting the heat insulation structure are made into units,
Since it is prefabricated, it can be easily installed and removed in a short time. (2) Since the heat insulating material is a heat insulating material with a skin, there is almost no generation of dust. (3) Especially in nuclear power plants and food factories,
Costs such as provision of a temporary clean room and local exhaust equipment were required to remove insulation (heat insulation) and to perform restoration work. However, such equipment is not required, and a great economic effect can be obtained. Can be. (4) Since each member constituting the heat insulating structure can be used repeatedly, the generation of industrial waste can be reduced. At the same time, it can greatly contribute to resource saving.
