Description

[Detailed description of the invention] The present invention relates to a filler element used in a catalytic action (contact) device between fluids and Regarding its improvement.

Various types of filler elements are known for use in fluid-fluid catalytic devices. Ru. Examples include the Raschig ring and the Pa ring. il), spiral ring (τellette) and mini ring (M 1ni-rin, gs), etc.

In addition, such filler elements can be used, for example, in distillation columns, reaction columns, gas purification equipment, etc. There is.

Many such elements are simple hollow tubular elements or modified shapes, with internal Those with directional ribs or tongues, openings in the inner wall, and flanges at the edges. There are some that have.

According to the invention, such a ring-shaped filler element has one row near each end. It has been found that making relatively small perforations increases the effectiveness.

That is, the filler element provided by the present invention forms a tubular member with an open end. A row of perforations is provided around the periphery of the perforation so as to contact each end thereof.

As already mentioned, the perforations are made relatively small, in that they are generally There is a marked difference from the opening seen.

However, it is usually convenient to have a circular cross section. The diameter of the perforation varies to some extent. is determined by the size of the filler element, and the larger the filler element, the larger the As the filler element becomes smaller, it is formed smaller accordingly. Therefore, perforation The dimensions of the tubular member can be expressed as a percentage of the length of the tubular member, e.g. It is expressed as 1-5% of the total length. Specifically, the diameter of the hole is 11m1. From 5ml to 1l is appropriate, preferably from 2II1m to 4alIIl. good.

- The distance between the centers of the perforations formed in the row is also determined by the dimensions of the filler element. Therefore, it can be expressed by the diameter of the perforation, and specifically, the distance is equivalent to 2 to 5 of the perforation diameter. It is appropriate to set it apart.

The number of perforation rows may be single or multiple, and in the case of multiple rows, adjacent perforation rows are flat. It doesn't have to be a line.

The row of perforations at the odd end of the tubular member is equivalent to 1 to 5 perforations from the end of the member in terms of perforation diameter. It is appropriate that they be placed a distance apart.

The tubular member forming the main body of the filler element has a cross section of any shape, such as a polygon or curved shape. It generally consists of a hollow cylinder with a circular cross-section, although it can be formed to have a flight For the sake of convenience, only the cylindrical tubular member will be described hereinafter.

The length of the tubular member, or the ratio of the diameter of the tubular member to its length, is the same as that of a conventional lashing ring. It can be set to 1 as in the case of pal rings, but generally the ratio of diameter to length is is greater than 1, at least 1.5:1, more preferably between 2:1 and 10:1. However, the ratio is more preferably 2.5:1 to 5:1.

The tubular member preferably has an outwardly directed flange at each end. By doing this, the Not only does the strength of the filler element increase, but the performance of the element is also increased, especially when configured in conjunction with a row of perforations. It increases. Such flanges may be formed substantially perpendicular to the surface of the tubular member. , or at an angle to that plane so that the edge of the flange is at the end of the tubular member. It may be formed to extend radially in the longitudinal direction.

In order to prevent the occurrence of fitting or rotation between the filler elements, the tubular member has multiple Preferably, ribs are provided extending inwardly from the wall of the member. Such ribs It also serves to increase the effective surface area of the filler element and is It may be configured so that it extends to a position and meets (or actually joins) the same part. It may be configured to extend halfway within the material.

The wall of the tubular member may be provided with openings located between the rows of perforations in a conventional manner. stomach. such opening generally has a larger cross-sectional area than each of the perforations forming the row of perforations; For example, if the filling material is made of metal, it may be formed to correspond to the inwardly directed tongues.
