において供給液を塔内充填層に均一に分散せしめ
ることは、極めて重要である。Conventional technology In recent years, due to advancements in synthetic resin materials, these synthetic resin molded products with excellent chemical resistance and moldability are often used for the internal packing of packed towers for gas-liquid contact, except in cases where heat resistance is particularly required. However, in place of Raschig rings, saddles, etc. made of conventional materials, more efficient ones with a shape that causes less pressure loss in the column have been devised and used. Therefore, it has become possible to process a much larger amount of liquid gas than in the past with the same column diameter. Under such circumstances, it is extremely important to uniformly disperse the feed liquid in the packed bed in the column.

に液を分散供給する構造となつている。 The liquid disperser for this purpose, like the packing material, affects the efficiency of the column, and various types have been devised over the years, including spray type, liquid column type (ring type, comb type), and porous type. Plate type, notched trough type, etc. are generally well known. Among these, the notched trough type is suitable for relatively large amounts of liquid and can also be used for obstructive liquids, an example of which is shown in FIG. This notched trough type is the liquid supply pipe 2.
The liquid is distributed and supplied to the liquid distribution weir 4 through an appropriate number of nozzle holes 3 provided on the lower surface, and the liquid is distributed to the distribution weir 5 below by each notch of the liquid distribution weir 4. The notches provide a structure in which the liquid is evenly distributed and supplied onto the packed bed.

して均一な液の分散供給は出来なくなつてくる。Problems to be Solved by the Invention In this notched trough type disperser, the amount of liquid from each nozzle hole 3 tends to become uneven due to the pressure gradient within the liquid supply pipe 2. For this reason, a method is adopted in which the diameter of the liquid supply pipe 2 is increased, the cross-sectional area of the nozzle hole 3 is reduced, and the liquid pressure within the liquid supply pipe 2 is increased to equalize the amount of liquid from each nozzle hole 3. but,
In such a method, not only does the power loss of the liquid supply pump occur, but also the nozzle hole 3 increases when the liquid volume is increased.
The impact of the ejected liquid against the bottom of the liquid distribution weir 4 increases, and most of the liquid scatters out of the liquid distribution weir 4 non-uniformly, making it impossible to uniformly distribute and supply the liquid.

ものである。 In other words, in the liquid dispersion device of the present invention, an appropriate number of liquid dispersion nozzles are provided vertically at the top of a horizontal liquid supply pipe, and the vertically spouted liquid flows into the liquid distribution weir installed directly below the liquid supply pipe. It has a structure in which it is dispersed and descends.

る。 Above the liquid supply pipe 2, a suitable number of liquid dispersion nozzles 3 of almost uniform length are provided vertically upward, and the supplied liquid is spouted vertically upward from the liquid dispersion nozzles 3, and is directly downward due to gravity. Most of the liquid flows down the outside of the liquid supply pipe 3 and flows into the liquid distribution weir 4 very smoothly.The liquid in the liquid distribution weir 4 overflows from the notch and is distributed to the distribution weir 5. It is uniformly distributed and supplied to the packed bed through the notches.
作 用
液分散ノヅルの何れからもほぼ均一に液を噴出
させるには、液供給管の液圧力は高めにする必要
があるが、従来の下向きの分散ノヅル穴では噴出
液が配液堰内を叩くことになり液は益々不均一に
飛散することになる。本考案においては供給液は
垂直に噴き上げられることにより液圧力を消費
し、更に降下する液が噴き上る液にぶつかつて液
の運動エネルギーを減殺すると共に大部分の液が
供給管の外側を伝わり、配液堰に落下することに
なり、液の叩きつけによる飛散はなくなり配液堰
は均等に液を分散堰に分配することが出来る。Function In order to eject liquid almost uniformly from all liquid dispersion nozzles, the liquid pressure in the liquid supply pipe must be high, but with conventional downward dispersion nozzle holes, the ejected liquid flows inside the liquid distribution weir. As a result of the pounding, the liquid will be scattered even more unevenly. In the present invention, the supply liquid is spouted vertically, consuming liquid pressure, and furthermore, the falling liquid collides with the rising liquid, reducing the kinetic energy of the liquid, and most of the liquid is transmitted outside the supply pipe. Since the liquid falls into the distribution weir, the liquid is no longer splashed due to slamming, and the liquid distribution weir can evenly distribute the liquid to the distribution weir.
