Description
【考案の詳細な説明】
この考案は例えば原子力発電所における原子力圧力容器
、タービンケーシング、ポンプ、バルブおよび配管など
（この明細書では原子力用機器という）に合着包囲して
使用する原子力用機器に用いる断熱保温体に関する。[Detailed description of the invention] This invention is applicable to nuclear power equipment that is used in a nuclear power plant by being enclosed in nuclear pressure vessels, turbine casings, pumps, valves, piping, etc. (referred to as nuclear equipment in this specification). Regarding the heat insulating body used.
金属製外板、内板および側枠で槽底された中空箱型のパ
ネルからなる保温体は、既に公知である（例えば特開昭
４９−１０６０１２号公報参照）。A heat insulating body consisting of a hollow box-shaped panel having a bottom formed by a metal outer plate, inner plate and side frame is already known (see, for example, Japanese Patent Laid-Open No. 106012/1983).
しかし、この種の保温体は内空部に絶縁材料として金属
製品が用いられているから断熱が充分でなく、また柔軟
性に欠は圧縮充填が十分行われない。However, this type of heat insulating body does not have sufficient heat insulation because a metal product is used as an insulating material in the inner space, and lacks flexibility and cannot be compressed and filled sufficiently.
そこでこの考案は絶縁材料として耐熱性、断熱性に優れ
、クッション性があって良好な充填が得られる耐熱性繊
維材料を用いた。Therefore, this invention uses a heat-resistant fiber material as an insulating material, which has excellent heat resistance and heat insulation properties, has cushioning properties, and can be filled with good properties.
しかし、繊維材料は原子力用に用いられるだけに特に放
射能を帯びた塵を発生する点が大きな欠点となる。However, since fiber materials are used for nuclear power applications, they have a major drawback in that they generate radioactive dust.
そこでこの考案は耐熱性繊維材料を小型にしてユニット
化し、これを表面を鏡面仕上げした金属箔で密封するこ
となく包んだのである。Therefore, this idea involved making heat-resistant fiber material into a compact unit and wrapping it in metal foil with a mirror-finished surface without sealing it.
次に図面に示すこの考案の１実施例によってこの考案を
説明すれば、１はこの考案に係るパネルで、金属性外板
２、内板３および合着面となる側枠４により半円筒形の
中空箱型に槽底されている。Next, this invention will be explained with reference to an embodiment of this invention shown in the drawings. 1 is a panel according to this invention, which is formed into a semi-cylindrical shape by a metal outer plate 2, an inner plate 3, and a side frame 4 serving as a joint surface. The bottom of the tank is shaped like a hollow box.
なお側枠４には多数の透孔が設けられている。Note that the side frame 4 is provided with a large number of through holes.
上記中空箱型内には小型でユニット化された耐熱性繊維
材料６を主体とする断熱ユニット５が隙間のない状態で
圧縮充填されている。Inside the hollow box shape, a small, unitized heat-insulating unit 5 mainly made of a heat-resistant fiber material 6 is compressed and filled without any gaps.
なお断熱ユニット５は耐熱性繊維材料６を鏡面仕上げし
た金属箔７で密封することなく包んでいる。The heat insulating unit 5 has a heat-resistant fiber material 6 wrapped in mirror-finished metal foil 7 without being sealed.
耐熱繊維材料６としてはセラミックファイバー、岩綿な
ど無機繊維のブランケット、フェルトが用いられ、金属
箔としてはステンレススチール、アルミニウムなどが用
いられ、輻射による熱の伝達を小さくするため表面を鏡
面仕上げをする。As the heat-resistant fiber material 6, ceramic fibers, blankets of inorganic fibers such as rock wool, or felt are used, and as the metal foil, stainless steel, aluminum, etc. are used, and the surface is mirror-finished to reduce heat transfer by radiation. .
また金属箔７の縁部は相方をラップしてスポット溶接す
るか折り返しにするか、何れにしても完全密封せず断熱
ユニット５内の空気が加熱され膨張した時に外へ流出す
るようにして金属箔７の破れをなくし、長期の使用を可
能としている。In addition, the edges of the metal foil 7 can be wrapped and spot welded, or folded back, or in either case, they are not completely sealed, but are made so that when the air inside the heat insulating unit 5 is heated and expands, it flows out to the outside. This eliminates tearing of the foil 7 and enables long-term use.
高速増殖炉では熱媒体として金属ナトリウムを使用して
おり、この金属ナトリウムは５６０℃の高温で配管の中
を流れるから、断熱ユニット５はセラミックファイバー
のブランケット、フェルトをステンレススチールの箔で
包んだ耐熱度の高いものを使用するのがよい。Fast breeder reactors use metallic sodium as a heat medium, and this metallic sodium flows through the piping at a high temperature of 560°C, so the insulation unit 5 is made of a heat-resistant ceramic fiber blanket or felt wrapped in stainless steel foil. It is better to use one with a high degree of strength.
以上述べたようにこの考案の原子力用機器に用いる断熱
保温体は、外装となる外板、内板および側枠が金属板で
槽底されてお・す、断熱ユニット５は金属箔７で密封さ
れず包まれているので破損せず、従って従来の断熱保温
体と同様の強度を保って耐用年数が長いのである。As mentioned above, in the heat insulating body used in the nuclear power equipment of this invention, the outer panel, inner panel and side frame are covered with metal plates, and the heat insulating unit 5 is sealed with metal foil 7. Since it is wrapped without being exposed to heat, it will not break, and therefore maintains the same strength as conventional heat insulating materials and has a long service life.
特にこの考案は本来断熱性を有する耐熱性繊維材料６が
金属箔７で包まれ、その金属箔７は加熱により破れるこ
とがなく、しかも金属箔７によって耐熱性繊維材料６は
多数の透孔からのはみ出しを押えられ損傷されることが
ないから発塵は全くない。In particular, in this invention, a heat-resistant fiber material 6 that originally has heat insulating properties is wrapped in a metal foil 7, and the metal foil 7 will not be torn by heating. Since the protrusion is suppressed and there is no damage, there is no dust generation.
従って放射能を帯びた塵が人体に耐着し、または吸引さ
れて人体に危害を与えることがない。Therefore, the radioactive dust will not stick to the human body or be inhaled, causing no harm to the human body.
更にこの考案は熱伝導が小さく軽い耐熱性繊維材料６を
金属箔７で包んだ断熱ユニツｌ−５を用い、また側枠４
等枠部分は多数の透孔が設けであるので、金属部分が少
なく熱伝導がきわめて少なく、かつ全体が軽量で取扱い
易く安価となる。Furthermore, this invention uses a heat insulating unit 1-5 in which a light heat-resistant fiber material 6 with low heat conduction is wrapped in metal foil 7, and also a side frame 4.
Since the equal frame portion is provided with a large number of through holes, there are few metal parts, so heat conduction is extremely low, and the whole is lightweight, easy to handle, and inexpensive.
