ばならない。 In a packed tower, perforated plates are provided at a fluid inlet and an outlet, and a filler is filled between the perforated plates, and the perforated plates rectify or separate the fluid to be treated. A perforated plate may also be provided in the middle of the column. Among these perforated plates, the perforated plate provided in the middle or lower part of the column also serves to support the packing. Therefore, these perforated plates must have sufficient strength to support the column packing and must have a structure that does not cause non-uniformity in the flow of the dispersing or gathering fluid.
しかるに、従来の多孔板は、円柱状の孔を設け

していたものである。 However, conventional perforated plates have cylindrical pores, and their porosity (the ratio of the total area of the pores of the perforated plate to the cross-sectional area of the packed tower) is at most
It was 0.25, and generally around 0.2. With conventional perforated plates that have holes with such a shape and porosity, non-uniform fluid flow occurs near the holes, which causes the performance of the packed column to fluctuate and become difficult to control. was. Of course, if the porosity is increased, the non-uniformity of fluid flow can be reduced, but increasing the porosity inevitably reduces the strength of the perforated plate. For this reason, the open area ratio was limited to 0.25.
本発明者らは、多孔板の強度を殆んど減少する
ことなく、流体の流れの不均一を極端に減少せし
め得る多孔板を見いだし、本発明をなすに至つた
ものである。 The present inventors have discovered a perforated plate that can significantly reduce the non-uniformity of fluid flow without substantially reducing the strength of the perforated plate, and have accomplished the present invention.
即ち、本発明は、充填塔の流体整流又は分集用
多孔板において、孔の横断面積が充填剤の充填側

充填塔の流体整流又は分集用多孔板に関するもの
である。 That is, the present invention provides a perforated plate for fluid rectification or separation of a packed tower, which is composed of pores having a shape such that the cross-sectional area of the pores is expanded toward the end surface on the filling side of the filler and becomes maximum at the end surface on the filling side. The present invention relates to a perforated plate for fluid rectification or separation in a packed tower characterized by the following.
本発明の多孔板は、厚み方向に沿つて異なる断

ことにより充填物側に流出し、又は充填物側から
流入する流体の流れは、スムースな流れを享受で
きる為流れの不均一は最小限に止められる結果と
なる。 The perforated plate of the present invention is made up of pores with different cross-sectional areas along the thickness direction, so the strength for supporting the filling material is maintained by the porosity of the minimum pore area, so it is durable. It is. In addition, by installing the hole with the end face with the largest cross-sectional area facing the filling side, the fluid flowing out to the filling side or flowing in from the filling side can enjoy a smooth flow. The result is that flow non-uniformities are minimized.
多孔板の孔の断面積の変化は連続的でも不連続
的でもよいが、連続的に、更には連続的にかつ直
線的に変化させることにより、流体に与える乱れ
のより少ない加工し易い多孔板を提供し得る。 The cross-sectional area of the holes in the perforated plate may change either continuously or discontinuously, but by changing it continuously or even continuously and linearly, the perforated plate can be easily processed with less disturbance to the fluid. can be provided.
断面積の変化は多孔板の厚み方向全体に亘る場
合ばかりでなく、その一部において変化していて
もよい。 The cross-sectional area may change not only over the entire thickness of the perforated plate, but also over a portion thereof.
本発明の多孔板の好ましい態様は、多孔板の孔

望ましい。 A preferred embodiment of the perforated plate of the present invention is a truncated conical shape, a combination of truncated conical shapes, or a truncated conical shape and a cylindrical shape, such that the rotational symmetry axis of the pores coincides with the fluid flow. This is a perforated plate in which the surface with the largest area of the truncated conical circular cross section is located on at least one end surface of the perforated plate surface. In order to maintain the mechanical strength of the perforated plate, it is desirable that the portion of the perforated plate in which 80% or more of the portions are not holes is 20% or more of the thickness.
又、上記特徴を有する孔が多孔板のすべての孔

20％以下の範囲が良い。 Further, the holes having the above characteristics do not necessarily correspond to all the holes in the perforated plate, and the holes in the perforated plate may include cylindrical holes in addition to the holes having the above characteristics. The degree of existence of the hole is determined by the total open hole area at the end face where the cross-sectional area of the hole is maximum.
A range of 20% or less is good.
多孔板の孔の形状を上記のようにすることによ

に小さくすることができ、しかも安価に製作でき
ることが分つた。 It has been found that by configuring the holes in the perforated plate as described above, the turbulence of the fluid in the packed bed near the perforated plate can be made very small, and it can be manufactured at low cost.

きる。 When using the perforated plate of the present invention, a mesh filter or the like whose particle size is smaller than that of the packing may be used to retain the packing in the packed column.
In this case, filters and the like may be pushed out into the holes of the perforated plate. Further, when a filter or the like is used in combination, there is a problem that the structure becomes complicated like the conventional perforated plate. As a solution to this problem, by filling and fixing a fine substance that does not pass through the filling in the pores of the perforated plate, even if a filter is used, there is no need to extrude the filter into the perforated plate. It becomes possible to hold the filling material without using any of the above, and the features of the present invention can be further utilized.

よりこの傾向は特に顕著になる。 A preferred perforated plate of the present invention is a perforated plate in which the porosity of the end face where the cross-sectional area of the pores is the largest (ratio of the total open pore area to the area inside the packed column at the end face) is 0.6 or more. Since the cross-sectional area of the holes is varied, even if the porosity of the end face is high, the porosity of the other parts is small, so the porosity of the end face can be adjusted while maintaining sufficient support strength. It is easy to set it to 0.6 or more. By setting such a porosity, it is possible to obtain a porosity that is considerably higher than the porosity of the filling particles. It will be erased even more. This tendency becomes particularly noticeable when the porosity is set to 0.8 or more.

その為流体の乱れが起こり、分離工効率が低かつ
たが、本発明の多孔板は強度を維持したまま開孔
率を上げることができる為好ましい。 The perforated plate of the present invention is effective when used in a chromatographic separation device in which fluid turbulence has a particularly large effect on separation efficiency. In particular, when using a separation device with an inner diameter of 10 cm or more, conventionally it has been impossible to increase the porosity larger than about 0.2 from the viewpoint of strength.
As a result, fluid turbulence occurred and the separation efficiency was low, but the perforated plate of the present invention is preferable because it can increase the porosity while maintaining strength.
更に内径50cm以上の分離装置に用いる場合に
は、従来は、上記欠点の他に流体の流れを均一に

き特に有効である。 Furthermore, when used in a separation device with an inner diameter of 50 cm or more, conventionally, in addition to the above-mentioned drawbacks, it was necessary to provide a large number of holes throughout the perforated plate in order to make the flow of fluid uniform. In the case of the perforated plate of the present invention, the number of holes can be reduced to about 1/2 to 1/10, and the porosity can be increased while maintaining strength, which is particularly effective.

The Na concentration was measured using an atomic absorption spectrometer, and the horizontal axis plotted the amount of liquid drained after injecting 10% saline, and the vertical axis plotted the Na concentration of the drained liquid to obtain a pulse waveform, and its shape Find out. If large turbulence of fluid occurs in the packed bed near the perforated plate,
The pulse waveform at the exit tends to exhibit greater tailing due to the presence of slow flow sections. Therefore, the pulse asymmetry coefficient was used as a measure of the difference in tailing.
パルスの非対称係数FTとは、パルスのピーク
高さの1/10におけるピーク位置より前のパルスの
幅WFに対する、ピーク位置から後のパルスの幅
（WR）の比である。 The pulse asymmetry coefficient F T is the ratio of the width of the pulse after the peak position (W R ) to the width W F of the pulse before the peak position at 1/10 of the peak height of the pulse.
FT＝WR／WF
このFT値が１より大きければ大きい程テーリ
ングの度合が激しいこと、即ち、流れの不均一性
の大きいことを示す。 F T =W R /W F The larger the F T value is than 1, the more severe the tailing is, that is, the greater the non-uniformity of the flow.
