Many patents related to filling materials have been proposed in the past, and examples of those related to this type of device include US Pat. No. 3,218,048 and Japanese Patent Publication No. 57-57165. However, in the conventional method, no consideration was given to preventing drift of fluid when the column diameter becomes large.

る。 In FIG. 1, a weaving yarn 2 is formed by bundling a plurality of fibers made of metal such as stainless steel, aluminum, copper, or synthetic resin, which does not absorb the liquid used in the tower. Since this weaving thread 2 is made by bundling a plurality of fibers 1, the fibers are in contact with each other or form small intervals, and liquid can flow between the fibers by capillary action, and the fibers 1 are made up of a plurality of fibers 1. The woven yarn 2 has stronger rigidity and better shape retention than one made of a single fiber. It also maintains appropriate elasticity,
Even when a large amount is packed into a packed column and the packing weight becomes considerable, the packing at the bottom that receives the weight will not be deformed. A fabric 3 is made from this weaving yarn 2. Several pieces of fabric are layered together and wound from the ends. Second
The figure shows a cylindrical filling. 4 is a strip-shaped thin plate wrapped between the laminates. The cylindrical packing with a spiral end face is formed with a diameter slightly larger than the diameter of the column it is packed in, and the filling state of the column is such that the outer periphery of the packing is always in pressure contact with the inner circumferential surface, as shown in Figure 3. . Therefore, vertical flow of the liquid used along the inner peripheral surface of the column is prevented, and the fluid is guided toward the center of the packing.

能となる。 In a packed column system, the factors that affect its performance include the specific surface area of the packing and the uneven flow of fluid flowing through the packing, but small-diameter packed columns are generally more efficient than large-diameter ones. is good. This is because the inner wall area of the packed column is added to the specific surface area of the packed material, increasing the apparent specific surface area.
Furthermore, this is because the biased flow of the fluid flowing through the filling while exchanging substances becomes smaller than the larger diameter. In the embodiment shown in FIG. 2, a strip-shaped thin plate 5 is inserted when the laminate 4 is rolled up in order to utilize the effect of the inner wall area and to prevent drifting. The material of the thin plate 5 is a metal thin plate such as aluminum or nickel, or a thin film made of a polymeric material. The thin plate 5 is a laminate 4
It is rolled up and formed to follow the shape of the laminate. The liquid falls onto the upper surface of the filling, enters the filling, and flows between the threads 2 formed of the fibers 1 by capillary action. A part of the flowing fluid comes into contact with the wall of the thin plate 5 inserted into the filling 4 and is again guided to the side opposite the wall surface. Therefore, even in large-diameter packed towers, the wall effect can be utilized in the same way as in small-diameter packed towers, and it is also possible to obtain the same performance as small-diameter packed towers, since drifting of fluid can also be prevented. .

効である。 In addition, as shown in FIGS. 3 and 4, the laminate 4
When forming the woven fabric 3, the laminate may be constructed by alternately providing uneven stripes on the fabric 3 by embossing so as to be diagonal to the mesh. When the laminate 4 is wound from the end and a thin strip 5 is wound in the middle to form a cylindrical packing and packed into a packed tower, the density of the packing becomes small, making it difficult to use for a large-diameter packed tower. It is valid.

のである。 In FIG. 5, a perforated plate with pores is used as a thin plate to be rolled into the filling material. By making the thin plate a perforated plate, the occurrence of drifting can be further prevented.

影響を最小限とする構造である。 FIGS. 7 and 8 show other embodiments of the invention. The components and operation are the same as those in the above-mentioned embodiments, but when the strip-shaped thin plates are rolled into the filling, the columnar shape is divided into several parts in the longitudinal direction, and the thin plates are arranged so as to be alternately shifted in the longitudinal direction. This structure minimizes the influence of drifting current.
