本発明は、向流形の気液接触装置に使用される通気及び
通液用の分散板（気液分散板）に係り、特に液体を均一
ζこ流下せしめるための通液孔の構造に関す′る。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a dispersion plate (gas-liquid dispersion plate) for ventilation and liquid passage used in a countercurrent type gas-liquid contact device, and in particular to This relates to the structure of the through hole for uniform liquid flow.
気体と液体を向流で接触させ、物質移動或いは熱移動の

ん塔である場合には液体の分散性がその性能を大きく左
右する。In a gas-liquid contact device that brings gas and liquid into contact with each other in countercurrent flow to perform mass transfer or heat transfer operations, it is important to uniformly disperse the gas and liquid. In particular, when the gas-liquid contact device is a packed tower, the dispersibility of the liquid greatly influences its performance.
このため、従来より液体の分散性を均一にする。Therefore, the dispersibility of the liquid is made more uniform than before.

造では気液分散板の下面が液切れに悪影響を及ぼし、良
好な液分散が行われない欠点があった。For example, there is a structure of a gas-liquid dispersion plate described in Japanese Patent Publication No. 57-1281. However, in the past, the structure was complicated. Further, as for a gas-liquid distribution plate having a simple structure, a gas-liquid distribution plate that simply has liquid holes in the plane of the gas-liquid distribution plate as liquid passage holes in addition to ventilation pipes is common. However, this structure has the disadvantage that the lower surface of the gas-liquid dispersion plate has an adverse effect on liquid drainage, and good liquid dispersion cannot be achieved.

。In order for the liquid to flow down uniformly through the gas-liquid distribution plate, the physical properties of the liquid must be taken into consideration. When the liquid that has passed through the liquid holes leaves the bottom surface of the distribution plate, it is important that the liquid flows down without moving on the bottom surface of the distribution plate.

明の目的は、構造か簡単で、更に良好な液分散性を得る
ことができる気液分散板を提供することにある。However, in order to obtain good liquid dispersibility, there is a problem that the structure becomes complicated and the manufacturing cost becomes high as in the above-mentioned prior art. On the other hand, if the gas-liquid dispersion plate has a simple structure, good liquid dispersibility cannot be obtained, and the performance of the gas-liquid contacting device cannot be fully exploited. An object of the present invention is to provide a gas-liquid dispersion plate that has a simple structure and can obtain better liquid dispersibility.

防ぐことが重要である。上記目的は、気液分散板の通液
孔の下面側に各々の通液孔の周囲に液切り用の溝を設け
ることにより達成される。In order to solve the second problem, when the liquid passing through the liquid passage hole leaves the bottom surface of the gas-liquid distribution plate, it is necessary to avoid the influence of the bottom surface of the gas-liquid distribution plate or the liquid flowing down from other liquid passage holes. It is important to prevent interference. The above object is achieved by providing a groove for draining liquid around each liquid passage hole on the lower surface side of the liquid passage hole of the gas-liquid distribution plate.

た、分散板下面での液の横方向への移動が溝によりさえ
ぎられるため良好な液体の分散性を得ることができる。A bay provided around the liquid passage hole acts as a drain for liquid flowing down from other liquid passage holes. Therefore, the liquid flowing down from the lower surface of the ventilation distribution plate through the liquid passage hole flows down without being interfered with by the liquid flowing down from other liquid passage holes. Further, since the lateral movement of the liquid on the lower surface of the distribution plate is blocked by the grooves, good liquid dispersibility can be obtained.

てん物である充てん塔について説明する。A first embodiment of the present invention will be described below with reference to FIGS. 1A and 1B. FIG. 1A shows a sectional view, and FIG. 1B shows a plan view from below. Reference numeral 1 denotes a vent pipe that allows gas from below to flow upward, and 2 indicates a liquid passage hole that allows liquid flowing down from above to flow downward, and these are installed uniformly or randomly on the gas-liquid distribution plate 4. 5 is an outer wall of the gas-liquid contact device. The liquid passage hole portion on the lower surface of the gas-liquid distribution plate 4 is provided with a liquid cutting groove 3 formed concentrically with the liquid passage hole 2 . The gas-liquid distribution plates 4 are installed at several locations in the vertical direction within the gas-liquid contact device constituted by the outer wall 5. Next, the present invention will be explained in detail. Here, a packed tower in which the gas-liquid contact member installed inside the gas-liquid contact device is a packing will be described.

を良くするためには、通気孔より流下する液体の圧力を
大きくすればある程度改善できる。The liquid fed from the top of the packed column comes into countercurrent contact with the gas rising from the bottom and flows through the individual packed initial layers. Since the liquid flowing down the initial packed layer is a natural flow, if the length of the initial packed layer is long, it becomes difficult to uniformly flow the liquid down across the cross section of the packed tower. Therefore, the gas-liquid distribution plate is installed before the liquid flows down the initial layer and its uniformity deteriorates, and it prevents the liquid from coming in from above and distributes it evenly over the entire cross section of the packed tower. Then, it is supplied again into the lower filling layer. In the gas-liquid distribution plate, the gas from below flows down through the vent pipe 1. The depth of the liquid accumulated on the flat plate of the distribution plate is approximately proportional to the square of the amount of liquid. Further, in order to improve the dispersibility of the liquid, it can be improved to some extent by increasing the pressure of the liquid flowing down from the vent hole.

塔高さの増大、あるいは、液深さが液体物量の２乗に比
例することから、操作条件又は増減運転が困難となる。The pressure can be increased by increasing the depth of the liquid on the distribution plate. However, increasing the liquid depth increases the height of the packed column, or because the liquid depth is proportional to the square of the liquid quantity, it becomes difficult to adjust operating conditions or increase/decrease operation.

の移動がなくなり、良好な液分散を得ることができる。For this reason, it is desirable that the liquid depth on the distribution plate be as small as possible. The liquid flowing down onto the flat plate on the gas-liquid distribution plate 4 from above flows into the liquid passage hole 2 while maintaining a constant liquid depth on the distribution plate. The liquid coming out of the liquid passage hole forms droplets on the lower surface of the liquid passage hole and adheres to the lower surface of the distribution plate. Further, when the liquid is supplied to the liquid passage hole, the balance between the viscosity or surface tension of the liquid and the weight of the droplet is lost, and the liquid flows downward. Here, when there is no liquid cutting groove as in the conventional technology (that is, when there is only a liquid passage hole), when the liquid leaves the liquid passage hole and flows down, it is affected by the lower surface of the dispersion plate and the adjacent liquid passage hole is affected. Uniformity deteriorates because it merges with the liquid and flows down. This causes a decrease in the efficiency of gas-liquid contact. On the other hand, in the embodiment shown in FIGS. 1A and 1B, the liquid cutting groove provided below the liquid passage hole makes it easier for the liquid from the liquid passage hole to separate from the gas-liquid distribution plate. Therefore, the liquid that has passed through the liquid passage holes flows down independently without being affected by the lower surface of the gas-liquid distribution plate. Therefore, the liquid in the gas-liquid distribution plate of the present invention is uniformly dispersed and flows down the cross section of the packed tower. In addition, when the gas-liquid distribution plate is installed at an angle due to the inclination of the tower or an error in the installation of the gas-liquid distribution plate, the liquid drainage grooves act particularly effectively, and the gas-liquid distribution plate without liquid drainage grooves There is no movement of liquid in the direction of inclination on the lower surface, and good liquid dispersion can be obtained.

。According to the present invention, the simple structure of providing liquid drainage grooves around the liquid passage holes of the gas-liquid distribution plate can improve the drainage of liquid from the gas-liquid distribution plate, and improve the uniform dispersion of the liquid. Obtainable. Furthermore, good liquid dispersion can be obtained even when the gas-liquid dispersion plate is tilted without adversely affecting the liquid dispersion.
