Definitions

  • reaction apparatus tubes for tube furnaces provided with filling bodies.
  • a vertically arranged outer tube has an axially extending concentrically arranged inner tube whose latter outer wall is spaced from the inner wall of the outer tube. This provides for counterflow, however, there may be in place of the inner tube a rod member extending axially within the outer tube.
  • Filling bodies are supported from the inner tube or the rod.
  • carrier elements in the form of uniformly spaced apart radially extending pins are welded at one end to the outer surface of the inner tube or rod.
  • shelf-like members extending in uniform spaced apart radial direction are secured to the outer surface of the inner tube or rod.
  • the filling bodies have an aperture therethrough and they are slidably received on the pins.
  • These filling bodies may be annular with oppositely extending frustrum of a cone ends and two may be pushed onto a carrier pin.
  • the outer bodies in -a radial direction have a greater diameter so that the intervals between the individual filling bodies in the peripheral direction remain approximately equal.
  • the filling bodies are freely supported.
  • the filling bodies here may take the shape of generally cylindrical members. The filling bodies in all cases are held in position with respect to each other in a uniform predetermined arrangement whereby equal flow conditions exist at all points within the tube and the Weight of the filling bodies is carried by the respective carrier elements.
  • This invention relates to tubes for tube furnaces, provided with filling bodies.
  • Tubes which contain a so-called stationary bed of filling bodies are frequently used in chemical work.
  • the filling bodies can here frequently fulfill a plurality of functions at the same time and possess for example an absorbing, flow-guiding, heat-storing or even catalytic action.
  • numberless variants have been developed as regards their outer form and also as regards their material composition.
  • fragments, balls, tablets or rings are used as tube filling bodies.
  • the arrangement of the filling bodies can influence very substantially the course of a process and must be determined for example according to the desired speeds of through-flow, sojourn times, heat-storage values, catalyst surfaces and the like.
  • the manner of the arrangement of the filling bodies has a particular influence upon the mechanical stressing of the tube walls and any installations thereupon and upon the filling bodies themselves. If the filling bodies are introduced by free pouring, which is almost always the case in tubes with relatively small diameter, additional stresses of the tube walls occur as considerable horizontal forces are exerted upon the tube walls as a result of the heaping angle of the bulk material being poured. Moreover the lower filling bodies are considerably stressed by the weight of the upper filling bodies and cannot carry out without hindrance, movements caused by temperature differences. These difficulties naturally become greater with greater pouring heights, narrower tubes and greater more frequent temperature fluctuations. The ratio of the tube diameter to the filling body diameter also plays a substantial part here.
  • the agglomeration of the filling bodies here firstly considerably falsifies the course of the process in the reaction tube and finally can completely suppress it, if the pressure loss occurring in the caked filling body mass exceeds the acceptable amount.
  • the invention provides, for tubes provided with filling bodies, that each individual filling body is held in a predetermined position by carrier elements, which in the case of counter-current tubes are secured on the outer surface of the inner tube or in the case of single tubes are secured on an insert of rod form extending axially of the tube.
  • the carrier elements for the filling bodies are formed as metallic pins welded on the inner tube or rodshaped inserts, upon which one or more annular filling bodies can be pushed.
  • the loads to be taken up here by each individual carrier pin are so minimal that relatively thin wire pins of appropriately refractory high-grade steel can be used, without need to fear bending thereof.
  • the provision of such carrier pins is possible in a rapid and simple manner by means of modern spot-welding guns and the fitting or threading of the individual filling bodies on to the carrier pins can also take place in a relatively short time. In any case the extra expense involved therein bears no relation whatever to the advantages explained above which are obtained with the construction according to the invention.
  • the carrier elements can also be formed as support elements upon which the filling bodies rest freely, in which case then the support elements are expediently formed from a plurality of support ribs or the like, between which there remain in each case gaps for the through-flow of the reaction media.
  • the carrier elements can expediently be secured to the inner tube or rod-shaped insert with slight downward inclination, since this achieves a more stable arrangement of the filling bodies on the carrier elements.
  • the individual filling bodies can be formed with a shape widening conically towards the outer wall of the tube or in the case of the association of a plurality of filling bodies with the individual carrier elements these can be made correspondingly greater with increasing radial distance, in such manner that the interspaces between the individual filling bodies remain approximately equal in the peripheral direction.
  • FIGURE 1 is a lateral view of filling bodies secured on the inner tube of a counter-current tube unit according to the invention, the outer tube being omitted,
  • FIGURE 2 is a vertical along the line I-I in FIGURE 1 with outer tube
  • FIGURE 3 is a horizontal section through the arrangement according to FIGURES 1 and 2,
  • FIGURE 4 is a perspective view of a modified filling body embodiment with associated carrier pins.
  • FIGURE 5 is a lateral view similar to FIGURE 1, showing a modified embodiment of filling bodies and carrier elements,
  • FIGURE 6 is a section along the line 11-11 in FIG- URE 5,
  • FIGURE 7 is a lateral view similar to FIGURES 1 and 5, showing a further variant of the embodiment of filling bodies and carrier elements, and
  • FIGURE 8 is a section along the line III-III in FIG- URE 7.
  • the invention is explained with reference to a so-called counter-current tube, in which the invention can be used with particular advantage, since the inner tube of such counter-current tubes can be utilized for the securing of the carrier elements for the individual filling bodies.
  • the invention is obviously however also usable for simple tubes, in which case it is necessary to use a special insert of rod or tube form for the securing of the carrier elements, in place of the inner tube which is present in counter-current tubes.
  • FIGURES 1-3 show an especially advantageous form of embodiment of the invention, in which metallic carrier pins 3 are secured on the inner tube 2 of a counter-current tube unit in regular geometric arrangement so that regular interspaces are produced between annular filling bodies 4 pushed on to the carirer pins 3.
  • two annular filling bodies 4 are pushed on to each carrier pin 3, the outer filling bodies in the radial direction having a greater diameter so that the intervals between the individual filling bodies in the peripheral direction remain approximately equal.
  • further filling bodies or only one filling body on each carrier pin depending upon the size of the annular gap between inner tube 2 and outer tube 1.
  • the individual filling bodies can be made to widen conically towards the outer wall, in order to achieve a still better space utilization and still more regular flow conditions through constant interspaces between the individual filling bodies'in the peripheral direction.
  • the arrangement of the individual filling bodies 4a in accordance with the invention permits the selection of special shapings thereof which increase the effect of the filling bodies, without any danger of these filling bodies being destroyed by reason of their radial or axial bores or the like. Even profiled carrier pins 3a are usable.
  • FIGURES 5 to 8 are similar in principle to the embodiment according to FIGURES 1 to 4.
  • the filling bodies 4b and 4c are merely made spherical or cylindrical in place of the annular filling bodies 4 in the embodiment according to FIGURES 1 to 4, and rest on correspondingly formed support elements 3b and 30 respectively secured on the inner tube 2.
  • Naturally further modifications of the forms of the utilized filling bodies and of the carrier elements carrying these are also possible. It is essential only that each individual filling body is held in a predetermined position by the nature of its support and receives adequate space for movements caused by temperature, and that the outer tube jacket remains unloaded, so that it is not additionally stressed by the filling bodies.
  • the invention even permits utilization of filling body materials which have a chemically or physically attacking effect upon the tube material.
  • protective caps of neutral material on the outer ends of the carrier elements.
  • highly delicate tube materials for example ceramics or quartz, for certain special purposes.
  • the use of such materials becomes possible for the first time, since they are poorly capable of withstanding the stresses as described above which ocour on free pouring of filling bodies.
  • Reaction apparatus comprising in combination,
  • Apparatus according to claim 1 wherein the axially extending support means within the tube is an inner generally concentric tube.
  • the filling bodies have an aperture therethrough and a plurality of the filling bodies are allocated to the individual metallic pins, said filling bodies possessing correspondingly larger dimensions with increasing radial distance, so that the interspaces between the individual filling bodies remain approximately equal in the peripheral direction.
  • the carrier elements are metallic pins having one end Welded to said rod and the filling bodies have apertures therethrough through which the pins extend.
