分散性の点で尚満足すべきものでなかつた。 In a liquid dispersion device, the natural fall method has almost no velocity energy remaining in the dispersed droplets compared to the spray method or rotation method that uses water pressure, so there is less re-scattering and the generation of mist, and the dispersibility of the liquid is improved by water pressure. Although it has the advantage of being almost unaffected by changes in the liquid, the distribution flow to each spray gutter that is arranged at an appropriate pitch tends to be uneven in various parts, and the uniform dispersion of the liquid is still unsatisfactory. It wasn't something I should have done.

れる。 In the figure, 1 is a liquid distribution gutter with both ends closed, and the mouth end of the gutter 1 is appropriately reinforced with a U-shaped reinforcing tool 2 to prevent it from being opened unnecessarily. .

かに小さくされている。 3 is connected to the distribution gutter 1 in order to supply liquid into the gutter 1.
The liquid supply pipe 3 is a liquid supply pipe with a closed end inserted so that at least the lower part is submerged in the liquid over almost the entire length in the length direction. Each of the liquid supply holes 4 is provided with a flow stop portion 5 protruding downward from the lower end of the liquid supply pipe 3 near the front side thereof. There is. When the diameters of the liquid supply holes 4 are the same, the amount of liquid that flows out tends to be somewhat larger as it approaches the tip, so in order to eliminate such variations in the amount of flow, the diameter of the liquid supply holes 4 should be adjusted. The ones closer to the front end are slightly smaller.

る。 Reference numeral 6 denotes a large number of parallel end-blocking blocks, which are horizontally extended and connected on both side walls of the liquid distribution gutter 1 in a direction perpendicular to the axis of the gutter 1 so as to receive liquid distribution from the gutter 1. The sprinkler gutter 6 has on both sides of the lower part of the side wall,
are formed at appropriate intervals in the length direction,
It is provided with a large number of spray holes 7 through which the liquid flows out with the total pressure between the water head and the liquid surface, and the spray holes 7 are provided alternately on each side wall so as to be shifted by half a pitch. The liquid dispersion gutter 6 can be connected to the side wall of the liquid distribution gutter 1 at a position that exactly coincides with the liquid supply hole 4 of the liquid supply pipe 3. The shape of the liquid distribution gutter 1 and the liquid distribution gutter 6 can be arbitrary. For example, if U-shaped, V-shaped, or U-shaped cross sections are used, the static pressure loss of the gas-liquid contact device can be reduced, and the water level can be reduced by a small amount. It is advantageous because it can be kept in liquid.
上述の構成を有する本考案装置に於て、液は給
液管３よりその下端の給液穴４を経て配液樋１内
に入り、この樋１内より各散液樋６内に分配され
つつ該樋６の散液穴７より、液面との間の水頭を
全圧として散液される。 In the device of the present invention having the above-mentioned configuration, the liquid enters the liquid distribution gutter 1 from the liquid supply pipe 3 through the liquid supply hole 4 at the lower end thereof, and is distributed from within this gutter 1 into each of the dispersion gutter 6. At the same time, the liquid is sprayed from the liquid spray hole 7 of the gutter 6 with the total pressure between the water head and the liquid surface.
この際本考案に於ては、特に散液管６に液を分

樋１を設置すると共に、配液樋１内に対する液の
供給を、その液中に没するように挿設した給液管

略々1/2程度に低減でき、給液系の負担を軽減で
きる。一方給液量を一定とした場合は、管浸漬に
よつて液面高さが上昇するので、散液性能の向上
に寄与できる。 At this time, in this invention, in order to especially distribute the liquid to the liquid distribution pipe 6, the liquid distribution gutter 1 is installed between the liquid supply pipe 3 and the liquid distribution pipe 6, and the liquid to the liquid distribution gutter 1 is Since the liquid is supplied from the liquid supply pipe 3 inserted so as to be submerged in the liquid, the liquid level in the liquid distribution gutter 6 rises by the amount that the liquid supply pipe 3 is immersed in the liquid. Therefore, the amount of liquid to be supplied necessary to obtain a predetermined liquid level height may be reduced by the immersion volume of the tube 3. For example, when the entire tube is immersed as in the illustrated embodiment, the amount of liquid to be supplied may be reduced by approximately the amount of liquid supplied. It can be reduced to about 1/2, reducing the burden on the liquid supply system. On the other hand, when the amount of liquid supplied is constant, the liquid level height increases due to tube immersion, which can contribute to improving the liquid dispersion performance.

作用とにより、その流出速度成分を著るしく弱め

１よりの散液樋６…に対する液の分配は、整流状
態下で各部均一に行なわれることになり、各散液
樋６に対し、全く同じ条件で液の分配を達成で
き、その均一分散性を著るしく向上できる。 Furthermore, the liquid is supplied from the liquid supply pipe 3 into the liquid distribution gutter 1.
The liquid supply hole 4 at the lower end of the liquid supply pipe 3 submerged in the liquid... is carried out while stopping the flow in the forward direction by the flow stop part 5 provided downward and near the front side of each liquid supply hole 4. With this structure, the outflow velocity component of the liquid flowing out from the liquid supply hole 4 into the liquid distribution gutter 1 is significantly weakened due to the downward flow and the flow blocking action of the flow stop part 5. As a result, the liquid is supplied into the liquid distribution gutter 1 with almost no directional component in the direction of the liquid distribution gutter 6, and the liquid supply holes 4 have a larger diameter as they are closer to the front end. Since the liquid supply hole 4 is slightly smaller, the amount of liquid flowing out from each part of the liquid supply hole 4 is uniform, and therefore the entire liquid level of the liquid distribution gutter 1 is uniform. Therefore, the distribution of the liquid from the liquid distribution gutter 1 to the sprinkler gutter 6 is uniformly performed in each part under the rectified flow condition, and the liquid is distributed to each of the liquid spray gutter 6 under exactly the same conditions. The uniform dispersibility can be significantly improved.
更に供給液は配液樋１内に一たん貯えられた後
に各散液樋６に分配されるようになつているの
で、供給液量が変化た場合であつても、配液樋１
内の水位が単に変化するだけで、散液樋６…に対
しては依然として整流状態下で液の分配が行なわ
れ、その均一分散性をそのまま保持できる。 Furthermore, the supply liquid is temporarily stored in the liquid distribution gutter 1 and then distributed to each of the liquid distribution gutter 6, so even if the amount of the supplied liquid changes, the liquid distribution gutter 1
By simply changing the water level inside, the liquid is still distributed to the liquid dispersion troughs 6 under a rectified state, and its uniform dispersibility can be maintained as it is.
更に配液樋１内には給液管３が、少なくとも下
部が没するように挿入されているので、その液中
没入体積分だけ、樋１内の水位が上昇し、供給液
量が少なくなつた場合でも支障なく散液樋６への
液の均一分配を達成でき、更に散液樋６は開放型
であるのでメンテナンスが容易であるなどの利点
がある。 Furthermore, since the liquid supply pipe 3 is inserted into the liquid distribution gutter 1 so that at least the lower part is submerged, the water level in the gutter 1 rises by the volume immersed in the liquid, and the amount of liquid supplied decreases. Even in such a case, the liquid can be uniformly distributed to the spray gutter 6 without any problem, and since the spray gutter 6 is open, maintenance is easy.
更に冷水塔などのように散布された液体が充填
物上に衝突するような用途に使用された場合であ
つても、液体が全面から均一にしかも余分な速度
エネルギーを持つことなしに自然落下されるの
で、飛沫やミストの発生が少なく、液滴捕集装置
などの併設の必要性を回避できる。 Furthermore, even when used in applications where the sprayed liquid collides with the filling, such as in a cooling tower, it is possible for the liquid to fall uniformly from the entire surface and without any extra velocity energy. As a result, less splashes and mist are generated, and the need for a droplet collection device can be avoided.
尚本考案に於て、配液樋１から散液樋６への液
の流入に際し、液面に僅かの波形を生じ、この波
形は、液の均一分散性に多少の悪影響を与える

では、その逆に形成位置をいくぶん低くし及び又
は穴径を大きくするなどの手段を適用することに
より、容易に解消できる。 In the present invention, when the liquid flows from the liquid distribution gutter 1 to the dispersion gutter 6, a slight waveform is generated on the liquid surface, and this waveform has a somewhat negative effect on the uniform dispersion of the liquid. The adverse effects of such waveforms can be solved by, for example, making the formation position of the spray holes 7 somewhat higher and/or reducing the hole diameter where the liquid level is high, and conversely by making the formation position somewhat lower where the liquid level is low. This problem can be easily resolved by applying measures such as increasing the hole diameter and/or increasing the hole diameter.
このように本考案装置に於ては、比較的少ない

の供給系の負担を軽減できると共に、各分配樋６

る。 In this way, the device of the present invention can secure a predetermined liquid level height by supplying a relatively small amount of liquid, reducing the burden on the liquid supply system, and also
Since the liquid can be distributed under rectified conditions, uniform dispersibility can be obtained and the performance of this type of liquid dispersion device can be improved.
