【考案の詳細な説明】 （産業上の利用分野） 本考案は、例えば液化ガス等の気化装置に使用する散水
装置の偏流防止装置に係るものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drift prevention device for a water sprinkler used in a vaporizer for liquefied gas, for example.
（従来の技術） 液化ガスの気化装置等に使用している散水装置は、例え
ば第１図に示すようにトラフの外側壁上部のエッジまで
水面を上昇させ、そのエッジからオーバーフローさせる
ことにより、液化ガスが導入されているパネルに対して
散水していた。(Prior Art) A sprinkler used in a vaporizer for liquefied gas, for example, as shown in FIG. 1, raises the water surface to the upper edge of the outer wall of the trough, and overflows from the edge to liquefy the liquefied gas. Water was sprayed on the panel where gas was introduced.
（考案が解決しようとする課題） このような構成のものは、水面に波立ち部が生じたり、
上記エッジが水平でないと偏流を起こして均一な散水を
実行することができず、このためエッジについては定期
的に調整を行う煩雑な作業が必要であった。(Problems to be solved by the invention) With such a configuration, a wavy portion may occur on the water surface,
If the above-mentioned edge is not horizontal, uneven flow occurs and uniform watering cannot be performed. Therefore, complicated work of periodically adjusting the edge is required.
本考案は、このような課題を解決し、トラフ外側壁の散

る。An object of the present invention is to solve such a problem and to prevent the uneven distribution of water sprinkling even when the horizontality of the water sprinkling portion of the outer wall of the trough is distorted or a wave portion is generated.

部材５を設けたものである。(Means for Solving the Problem) The means for achieving the above object will be described with reference to the drawings corresponding to the embodiments. In the drift prevention device of the present invention, in the outer wall 3 of the sprinkling trough 1, The water surface 7 is always located above and the water spray holes 4 are provided in the horizontal direction only at positions where the water head can be secured and maintained, and the water spray guide member 5 is provided at the lower end of the water spray holes 4.
（作用） 上記の構成に於いて、散水トラフ１内に海水等を供給し

非常に小さく、偏流を防止することができる。(Operation) In the above configuration, when seawater or the like is supplied into the water sprinkling trough 1 to maintain the predetermined water surface 7, the water in the water sprinkling trough 1 maintains the predetermined water head and the water sprinkling hole 4 Drained from. In this case, the flow rate of outflowing seawater is proportional to the square root of the head. Even if the horizontality of the water spray holes 4 is distorted or the water surface has a wavy portion, these changes are very small as compared with the above-mentioned head, and therefore the changes in the head due to these are very small. Therefore, the change in the flow rate is very small, and the drift can be prevented.
（実施例） 次に本考案の実施例を図について説明する。(Example) Next, the Example of this invention is described about a figure.

するように一対の整流板９を設けている。FIG. 2 shows a part of the seawater sprinkler. In this figure, reference numeral 1 is a sprinkling trough, and 2 is a panel provided outside the sprinkling trough 1 into which a liquefied gas or the like is introduced. Is. The outer wall of the water sprinkling trough 1 is provided with a water sprinkling hole 4 in a horizontal direction at a position separated by a predetermined distance from a position of a water surface 7 formed near the upper end, and a water sprinkling guide member 5 is provided at the lower end thereof. ing. The water sprinkling holes 4 may have a structure in which a large number of circular holes or oval holes are arranged in the horizontal direction, or may be composed of horizontal slit-shaped holes, but the latter slit-shaped holes are preferable. Reference numeral 6 is a seawater inlet, and this seawater inlet 6 is provided at the center of the lower end of the sprinkling trough 1. In the sprinkling trough 1, a pair of straightening vanes 9 are provided so that the seawater inlets 6 face each other with an intervening space therebetween and a gap 8 as a seawater passage is formed in the lower part.
以上の構成に於いて、海水は海水流入口６から散水トラ
フ１内に導入されて水面７が所定の高さに維持される。
海水流入口６からの海水は、前記一対の整流板９間に導
入されるので、後述する散水孔４からの流出に悪影響を
与えない。In the above structure, seawater is introduced into the sprinkling trough 1 from the seawater inlet 6, and the water surface 7 is maintained at a predetermined height.
Since the seawater from the seawater inlet 6 is introduced between the pair of straightening vanes 9, it does not adversely affect the outflow from the water spray holes 4 described later.
しかして散水トラフ１内の水は所定の水頭が確保維持さ
れた状態で散水孔４から流出する。この際に流出する流
量は前記水頭の平方根に比例する。即ち流量をｑ、水頭
をＨとすると、ｑ∝√Ｈである。Then, the water in the water sprinkling trough 1 flows out from the water sprinkling hole 4 in a state where a predetermined head is secured and maintained. The flow rate flowing out at this time is proportional to the square root of the head. That is, if the flow rate is q and the head is H, then q∝√H.
そこで、例えば水頭Ｈとして３００mmを確保維持してい
る状態に於いて、散水孔４の水平度が１mm狂ったとし
て、この狂いによる散水量の変化を求めると、 となり、散水孔４の水平度に狂いが生じた場合でも、こ
の狂いは前記水頭と比較して非常に小さいので、水頭の
変化も非常に小さい。従って流量の変化も非常に小さ
く、偏流を防止することができることがわかる。また、
水面に波立ち部が生じた場合でも、この波立ち部による
水頭の変化は非常に小さく、従って前述と同様に偏流を
防止することができる。Therefore, for example, in a state where the water head H is maintained and maintained at 300 mm, if the horizontality of the water spray hole 4 is deviated by 1 mm, a change in the amount of water sprinkled due to this deviation is calculated. Therefore, even if the horizontality of the water spray hole 4 is deviated, the deviation is very small as compared with the head, so that the change in the head is also very small. Therefore, it can be seen that the change in the flow rate is very small and the drift can be prevented. Also,
Even when a wave portion is generated on the water surface, the change in the water head due to the wave portion is very small, and therefore, the drift can be prevented as described above.

る。(Effects of the Invention) As described above, the present invention is configured to positively secure and maintain the water head between the water surface of the water sprinkling trough and the water sprinkling hole, and use the water head to discharge seawater or the like from the water sprinkling hole. Even when an error occurs in the horizontality of the water spray holes or when a wavy portion occurs, the change in the flow rate can be made extremely small, that is, the occurrence of drift can be reliably prevented. Therefore, the present invention has the advantages that the design and manufacture of the sprinkler can be facilitated and that the spout hole need not be regularly inspected.
