Definitions
- the invention relates to a clamp for releasably connecting a column tray to a support ring in a column and to a use.
- Rectification and absorption processes are particularly suitable as thermal separation processes. It is often necessary to treat thermally unstable substances that tend to polymerize under the process conditions. The following are particularly critical: the connecting elements between floors and support rings, i.e. the screws or clamps described above.
- a holding device for column trays is known from EP-A 0 856 343, an opening being provided in at least part of the holding device through which liquid can flow.
- a clip for releasably connecting a column tray to a support ring in a column, comprising a bolt and one with the Bolt-connected lower clamp part, the lower clamp part having at least one opening through which a liquid in the column can flow off.
- mass transfer columns which contain trays as partially effective internals, for the releasable fastening of the same support rings to the inner wall of the column are usually firmly connected, usually welded.
- the clip according to the invention for releasably fastening a column bottom with a support ring is formed in one piece, it comprises a bolt and a lower part of the clip connected to the same.
- the bolts of the brackets are usually also arranged vertically in the installed state.
- the lower clamp part which is movably connected to the bolt, has at least one opening through which the liquid located in the column can flow.
- the geometric configuration of the opening is not limited to a specific shape and size, it is only necessary that the opening is sufficiently large that liquid can flow through it.
- the cross-sectional shape of the opening or openings in the horizontal plane can in principle be arbitrary, for example round, semicircular or polygonal shapes are possible.
- the bolt and the lower clamp part are preferably connected via an axle joint that is movable in the vertical plane. This simplifies the installation and removal of the column trays.
- the bolt and lower clamp part are preferably made of stainless steel, preferably of stainless steel 1.4571 according to DIN 17007.
- the clip according to the invention is particularly suitable for use in an absorption and / or rectification column in which thermally unstable substances are absorbed and / or rectified. Contamination of the column due to deposits Polymerization of the thermally unstable substances can be considerably reduced by using the clip according to the invention.
- the clamp according to the invention is particularly suitable for use in rectification and / or absorption columns in which mixtures of substances containing one or more of the substances (meth) acrylic acid and / or their esters, acrylonitrile and / or styrene are treated.
- Figure lb shows a cross section through the longitudinal section shown in Figure la
- Figure lc is a longitudinal section perpendicular to that shown in Figure la
- Figure 2a shows a longitudinal section through an embodiment of a clip according to the
- Figure 2b shows a cross section through that shown in Figure 2a in longitudinal section
- Figure 2c shows a longitudinal section in the section plane shown perpendicular to Figure 2a.
- FIG. 1 a shows a clamp 1 with a bolt 2 and a clamp lower part 3, which are connected to one another via an axle joint 9.
- the bracket 1 is used Fastening a column tray 4 to a support ring 5.
- the bolt 2 is connected to the column tray 4 by means of a nut 6 and a seal 7.
- FIG. 1b illustrates the opening 8 in the lower clamp part 3, it being clear that the opening 8 completely penetrates the lower clamp part 3 in the vertical direction thereof.
- FIG. 1c also illustrates the complete expansion of the opening 8 in the vertical direction in the lower part 3 of the bracket.
- FIG. 2 shows a clip according to the prior art.
- the cross-sectional illustration in FIG. 2b and the longitudinal sectional illustration in FIG. 2c illustrate that the lower clip part 3 has no opening extending over the entire vertical extent thereof.
