As shown in Japanese Patent No. 281, there is a limit in the dispersibility of liquid and gas in the packing itself. On the other hand, regular-shaped packing represented by Melapak (Sulzer) has recently begun to spread in various fields because the packing itself has a certain degree of dispersibility of liquid and gas.

り性能の低下を防止している。In a packed tower packed with packing, the surface area of the packed column is inferior in performance due to the exchange of the gas phase and the gas phase which come into contact with the thin layer material which is the gas-liquid contact portion. Affect. When high separation performance is required, it is necessary to have a surface area as large as possible. On the other hand, in order to achieve sufficient gas-liquid contact, it is important to form a liquid film uniformly on a thin layer of the filler. In particular, uniform dispersion of the liquid on the inner wall of the packed tower and the region near the outer periphery of the packed material greatly affects the separation efficiency. In order to uniformly disperse the liquid into the filling, the liquid can be evenly distributed by installing a large number of liquid distributors installed above the filling or by increasing the number of drops of the liquid from the liquid distributor. The performance is prevented from deteriorating by a method of dispersing.

In other words, the dispersion in the longitudinal direction is easier due to the structure of the thin layer material constituting the filler, and the dispersion in the direction perpendicular to the longitudinal direction is slightly smaller. This phenomenon is particularly likely to occur in the outer peripheral portion of the packing and is caused by a decrease in efficiency. on the other hand,
In order to obtain a uniform dispersibility of the liquid in the outer peripheral portion, the liquid distributor becomes complicated, and it cannot be said that this is an appropriate measure from the viewpoint of equipment cost.

ことにより達成できる。In order to solve the above-mentioned problems, it is important to effectively disperse the liquid to the inner wall of the packed tower and the region near the outer periphery of the packed material. As a means for this, a liquid dispensing device with a packing that is configured such that the longitudinal direction of the thin layered article having a corrugated groove constituting the packing is substantially perpendicular to the circumference of the packing tower, This can be achieved by installing it above.

And the liquid can be widely dispersed as a result. Therefore, the liquid can be uniformly dispersed to the area near the inner wall of the packed tower and the outer periphery of the packed material,
Sufficient gas-liquid contact can be performed over the entire packed tower, and a packed tower with high separation efficiency can be provided.

充填物。7. A plurality of packings are provided in a plurality of stages in the axial direction, and each of the packings is constituted by a plurality of thin layers having corrugated grooves arranged in parallel in a packed tower. The layers are arranged such that their corrugated grooves intersect each other, and the lamina has a row of spaced pores, allowing liquid to flow down from the top, and from the liquid and the bottom. In a packed tower for gas-liquid contact in which an ascending gas is brought into cross-flow contact, a liquid distributing device for the packed material is installed above the packed material, and the liquid distributing device includes a plurality of thin layers constituting the packed material. The direction of the thin layer of the corrugated groove of the liquid distribution device is divided into at least three blocks, and the thin layer of the corrugated groove of each block is set to be shifted from each other by 90 degrees,
A packed material characterized in that the longitudinal direction of the thin layer material of each block is arranged substantially perpendicular to the circumferential portion of the packed tower, and these blocks constitute one element to form a liquid distribution device.
