Definitions

  • a) are aligned essentially vertically, b) run essentially parallel to each other, c) each have a filling opening.
  • Such reactors are used for example in catalytic processes in petrochemicals as catalysts. They consist of a large number of vertically aligned tubes, which are combined to form a tube bundle or tube package using one or more holding plates.
  • a catalytically active material usually in the form of a powder or granulate, is filled into these tubes via filler openings which are formed by open ends of the tubes.
  • the tube bundle is sealed gas-tight with the help of a bell, among other things, and the corresponding reaction gas is fed into the bell and then through the filling openings through the tubes.
  • the content of the tubes for example the granulate, then enables the desired reaction.
  • the device is relatively large and bulky, which is particularly disadvantageous if the reactor is gas-tight.
  • the bell must then be removed each time to fill in order to be able to install the entire device.
  • a complex positioning must also be carried out so that the holes are located exactly above the filler openings.
  • the EP-0 963 785 AI shows a device that is formed from individual segments. These individual segments can be placed on the filler openings with molded filler tubes.
  • the filling pipes extend in sections into the respective pipe and the segments are supported on the ends of the pipes.
  • the filling pipes are designed so that they are held in the pipes by clamping. For this purpose, they have ends tapering from the plate to their free shape and are additionally slit lengthways.
  • the diameter of the filler tubes is such that the free ends of the filler tubes can be easily inserted into the tubes or filler openings and then clamped by appropriate pressure.
  • EP-0 963 785 AI has some decisive disadvantages.
  • the production of molded parts, which usually consist of plastic is relatively complex.
  • the large number of edges and corners requires an exact shape in order to guarantee the surface-closing properties of the segments.
  • the angles between the individual pages must be made exactly.
  • Already slight deviations mean that a surface-covering installation is no longer possible, or at least is more difficult.
  • This in turn means that relatively high demands must be placed on the quality control of the segments produced, which is correspondingly time-consuming and costly.
  • the ratio of the cone angle of the filling pipes to the pipe diameter and the width of the slot must be selected exactly.
  • the filling pipes have to be clamped inside the pipe, on the other hand they have to penetrate so deep into the pipe that the horizontal surface of the segments facing the pipe end touches the pipe end in order to achieve a reasonably uniform surface by a To be able to create a large number of segments.
  • the straight edges of the polygonal segments can also block the filling material. If the segments are not exactly aligned in one plane, the straight edges of one segment protrude higher than the edges of the neighboring segment. When distributing The filling material then hits the raised edge and cannot get onto the segment. These grains in turn block other grains themselves, creating a kind of dam effect. The distribution of the filling material is made considerably more difficult.
  • the object of the present invention is to provide a loading device for a reactor which is formed from a multiplicity of tubes and which enables the reactor or the tubes to be loaded as quickly and easily as possible.
  • the loading device should be as simple and inexpensive as possible. It is also essential that the loading device is designed in such a way that incorrect use, for example by an inexperienced user, is almost impossible, or at least minimized. It is also essential that the loading device is suitable for gas-tight sealed reactors.
  • the loading device should be stable, resilient and easy to remove.
  • a loading device for a reactor which is formed from a multiplicity of tubes (50) which are oriented essentially vertically, run essentially parallel to one another and each have a filling opening (25) which consists of a multiplicity of loading elements that each have
  • a lateral outer contour which is formed by a circular shape with molded, diametrically opposite lugs, the lugs
  • tips which are arranged on an axis XX running through a center of the circular shape, 1.1.2) each form an isosceles triangle, which is delimited by two turning points in the outer contour of the circular shape and by the respective tip and the sides of which each have the same curvature pointing in the direction of a center point of the triangle.
  • the sides of the isosceles triangle adjoining the tip therefore have a curvature that corresponds to the amount of the curvature of the circular shape
  • An essential advantage of the present invention is that it is possible to form a continuous surface with the aid of the loading elements without having to align tips or corners with one another. Only circular sections nestle against each other, while the molded noses only close the gaps between the circular basic shapes. The laying or insertion of the loading elements is thus very easy and quick to carry out.
  • the curved outer contours of the loading elements also ensure that no blockages form even if the loading elements should not be aligned exactly in a horizontal plane. Contrary to the straight edges known from the prior art, the grains of the catalyst material are not stopped, but are diverted along the curvature. The dam formation known disadvantageously in the prior art is thus excluded.
  • the plate of the loading element has an opening which advantageously has a smaller diameter than the pipes to be filled. This narrowing of the cross-section influences the loading speed and the filling density of the pipes.
  • the opening is particularly advantageous with regard to these properties if the diameter of the opening is approximately 70% of the diameter of the filling pipe. This information is only to be understood as a guideline and can be adapted to the respective conditions and the granulate to be filled.
  • the loading speed and the filling density will continue to be improved according to that the plate is funnel-shaped around the opening.
  • the surface of the plate thus has a depression increasing in the direction of the opening.
  • the opening and also the depression are preferably circular and arranged coaxially with an axis extending through the center point of the opening at right angles to the opening.
  • the invention has further advantages over the prior art.
  • the device shown in EP-0 963 785 AI is also disadvantageous because the tubes of the reactors generally have welding seams that protrude into the interior of the tubes and extend along the tubes. These can lead to unwanted jamming and prevent the segments or their filling pipes from being fully inserted.
  • a longitudinal slot in the filler pipe compensates for the narrowing of the cross-section through the weld seam, but due to the lack of elasticity of the filler pipe at its base, i.e. close to the plate, a complete insertion is sometimes not possible.
  • the only way to avoid this disadvantage is to introduce the segment in such a way that the Weld is located in the area of the longitudinal slot.
  • this is again disadvantageous because a surface-closing arrangement is only given when the segments are aligned with one another, so it is not possible to align individual segments differently from the other segments due to the disruptive weld seam.
  • a loading device consisting of individual loading elements from above,
  • Fig. 2 a loading element according to the invention in section
  • FIG. 1 illustrates how a loading device 12 with an essentially continuously closed surface can be created from loading elements 10 according to the invention.
  • the individual loading elements 10 have a circular shape 14 as a basic shape, to which diametrically opposed lugs 16, each having a tip 18, are connected.
  • FIG. 2 shows the loading element 10 in the inserted state.
  • the loading element 10 has a filling tube 26 which is formed on an inner side 28 of a plate 30 of the loading element 10 around the opening 24.
  • FIG. 3 makes it clear (as can also be seen in FIG. 2) that in the area of the opening 24 the plate 30 has a depression 52 in the manner of a funnel, that is to say increasingly in the direction of the opening 24. This facilitates the filling of the pipes 50 or increases the filling speed.
  • FIGS. 4 and 5 illustrate an essential advantage of the shape of the plates 30 according to the invention.
  • the center points 20 of the respective segments are spaced apart from one another by exactly the same amount.
  • the segments according to the prior art can be rotated relative to one another by a significantly higher amount (14.7 °) than is the case with the plates 30 according to the invention (only 2.5 °).
  • the maximum openings or gaps in the plates according to the invention only allow grains 54 with a grain size of approximately 4 mm to pass. This difference leads to considerable advantages of the device according to the invention.
