【考案の詳細な説明】
この考案は自由液面を有する例えばポンプ、蒸気発生器
、タンク等のナトリウム機器に関するものである。DETAILED DESCRIPTION OF THE INVENTION This invention relates to sodium equipment, such as pumps, steam generators, tanks, etc., which have a free liquid level.
第１図に示すような従来のナトリウム機器１において、
自由液面２が安全な静止状態であれば問題ないが、例え
ばナトリウムポンプのように液面が変動するものにおい
ては、その変動の波立ちによりナトリウムが飛散してカ
バーガス系ノズル３に入り閉塞を起すことがある。In a conventional sodium equipment 1 as shown in FIG.
There is no problem if the free liquid level 2 is in a safe stationary state, but in devices where the liquid level fluctuates, such as a sodium pump, the ripples of the fluctuations can cause sodium to scatter and enter the cover gas system nozzle 3, causing a blockage. It can happen.
また、ナトリウム加熱蒸気発生器においては水素濃度計
にサンプルガスを流しておく必要があり、このように常
に排気を伴うガス系においてはとりわけ飛散ナトリウム
がガス系ノズルに入り易い。Furthermore, in a sodium-heated steam generator, it is necessary to flow sample gas through a hydrogen concentration meter, and in such a gas system that is constantly exhausted, scattered sodium is particularly likely to enter the gas system nozzle.
これまでに、蒸気発生器において自由液面より１．５ｍ
高い位置に取付けられたガス系ノズルにナトリウムが入
り閉塞したことがあった。Up to now, we have tested 1.5 m above the free liquid level in steam generators.
There was a case where sodium got into a gas nozzle installed in a high position and caused a blockage.
この考案の目的は、上記のような従来技術の欠点を解消
し、飛散ナトリウムがカバーガス系に入るのを防止する
ようにしたナトリウム機器を得ることにある。The purpose of this invention is to overcome the drawbacks of the prior art as described above and to provide a sodium device that prevents flying sodium from entering the cover gas system.
この考案は、内部に液体ナトリウムが収納され、該ナト

ことを特徴とするナトリウム機器である。This device is designed to be used in sodium equipment in which liquid sodium is stored inside and a cover gas system nozzle is opened in the cover gas space above the free liquid level of the sodium. This sodium equipment is characterized in that an umbrella-shaped flying sodium impactor is provided so as to cover the vicinity of the cover gas space and to have a top portion protrude toward the cover gas space.
以下図面に基づきこの考案について詳述する。This invention will be explained in detail below based on the drawings.
第２図はこの考案の一実施例であり、ナトリウムポンプ
や蒸気発生器等のすｌ−ＩＪウム機器１にナトリウム配
管６が形成され、該ナトリウム機器１にナトリウムが入
っている。FIG. 2 shows an embodiment of this invention, in which a sodium pipe 6 is formed in a sodium equipment 1 such as a sodium pump or a steam generator, and sodium is contained in the sodium equipment 1.
ナトリウム自由液面２の上方にはカバーガス系ノズル３
が形成されており、ナトリウム自由液面２の上方部はカ
バーガス層５となっている。Above the sodium free liquid level 2 is a cover gas nozzle 3.
is formed, and a cover gas layer 5 is formed above the sodium free liquid level 2.
カバーガス系ノズル３の先端は、ナトリウム機器１の内
壁よりも突出し、傘状の衝突体７ａが若干の間隙をもっ
てカバーガス系ノズル３の開口部を覆い、かつその頂部
がカバーガス層の方に向って突出するように配置されて
いる。The tip of the cover gas nozzle 3 protrudes beyond the inner wall of the sodium equipment 1, and the umbrella-shaped collision body 7a covers the opening of the cover gas nozzle 3 with a slight gap, and its top is directed toward the cover gas layer. It is arranged so that it protrudes towards the front.
自由液面２に波立ちがあるとカバーガス層５にナトリウ
ムの飛散が起こる。When the free liquid surface 2 is rippled, sodium scatters in the cover gas layer 5.
カバーガス系ノズル３からガスの排気が行われている場
合、そのガスにより飛散ナトリウムが持ちさられるわけ
であるが、飛散ナトリウムは衝突体７ａに当たり、方向
がそれるか、もしくは付着するため、ガス系トズルにま
で侵入することはない。When gas is exhausted from the cover gas system nozzle 3, the gas carries away the flying sodium, but the flying sodium hits the collision body 7a and either deviates from its direction or adheres to it, so that the gas It will not invade the system.
第３図はこの考案の他の実施例であり、ナトリウム機器
１の上方部のカバーガス層５に、ナトリウム自由液面２
の全面を覆い、かつ頂部が上方のカバーガス層に向って
突出するように傘状の衝突体７ｂを配置したもので、カ
バーガス層に大きな空間的余裕がある場合にはこのよう
な構成も有効である。FIG. 3 shows another embodiment of this invention, in which a sodium free liquid level 2 is added to the cover gas layer 5 in the upper part of the sodium equipment 1.
The umbrella-shaped colliding body 7b is arranged so as to cover the entire surface of the cylinder and protrude toward the upper cover gas layer. If there is a large space in the cover gas layer, such a configuration may be used. It is valid.
このように、飛散ナトリウム衝突体の形状を傘状とし、
その頂部が自由液面やカバーガス系開口部の方ではなく
、カバーガス空間の方に向って突出させたことによって
ナトリウムとガスとの混合流体（いわゆる飛散す１−リ
ウム）が衝突したとき、ナトリウムとガスとを効率よく
分離することができる。In this way, the shape of the flying sodium impactor is made into an umbrella shape,
By making the top protrude toward the cover gas space rather than toward the free liquid level or the cover gas system opening, when the mixed fluid of sodium and gas (so-called flying 1-lium) collides, Sodium and gas can be efficiently separated.
つまり、衝突体を傘状とすることによって重さの異なる
混合流体はこれにぶつかり、軽いガスは上方へ、重いナ
トリウムは衝突によって運動エネルギーを失うか、ある
いは方向が曲げられるなどして、ナトリウムがガス系ノ
ズルにまで侵入するのを防ぐことができ、傘状衝突体に
付着したナトリウムはその傾斜によってスムーズに流れ
落ちる。In other words, by making the colliding body umbrella-shaped, mixed fluids of different weights collide with it, and the lighter gas moves upward, while the heavier sodium loses kinetic energy due to the collision or its direction is bent, causing the sodium to collapse. It is possible to prevent the sodium from penetrating into the gas nozzle, and the sodium adhering to the umbrella-shaped collision body flows down smoothly due to its slope.
それ故、急激な液面変動等によってカバーガスの流動が
生じても、捕捉されたナトリウムが更に上方に運ばれる
こともない。Therefore, even if the cover gas flows due to sudden changes in the liquid level, the trapped sodium will not be carried further upwards.
更に、傘状としたことにより強度が強く変形しにくいと
いった作用効果がある。Furthermore, the umbrella-like shape has a strong strength and is resistant to deformation.
この考案は上記のように構成したことによって、ナトリ

ス系ノズルの閉塞を防止することができるものである。By configuring this device as described above, the sodium free liquid level in the sodium equipment can be prevented from undulating.
Furthermore, even if there is a cover gas system that involves exhaust, it is possible to prevent scattered sodium from entering the cover gas system and to prevent clogging of the gas system nozzle.
