Description
Kontaktapparat für katalytische Verfahren.Contact apparatus for catalytic processes.
Bei Kontaktapparaten für katalytische Verfahren, z. B. zur Herstellung von Schwefelsäure, wird der Kontaktträger, in diesem Fall Platinasbest, in der Regel auf einer Anzahl von übereinanderliegenden Siebböden ausgebreitet und die Gase werden von unten nach oben durch den Apparat hindurchgeleitet. Als Material für diese Siebböden wird im allgemeinen gelochtes Blech aus Schmiedeeisen verwendet, besser sind jedoch die ebenfalls bekannten gelochten Platten aus Gußeisen. Bei dem Bestreben, immer größere Leistungen mit solchen Apparaten zu erzielen, sind naturgemäß auch die Abmessungen derselben gewachsen. In contact apparatus for catalytic processes, e.g. B. for production of sulfuric acid, the contact carrier, in this case platinum asbestos, is usually spread out on a number of superimposed sieve trays and the gases are passed through the apparatus from bottom to top. As a material for these sieve trays Perforated wrought iron sheets are generally used, but are better the well-known perforated cast iron plates. With the endeavor, always Obviously, to achieve greater performance with such devices are also the dimensions grown to the same.
Die vergrößerten Kontaktapparate weisen den überstand auf, daß bei vorkommender ungleichmäßiger Ausbreitung der Kontakt- -masse die Temperaturen an einzelnen Stellen des Apparates verschieden sind. Dadurch entstehen Störungen im gleichmäßigen Gasdurchtritt. Die Gase suchen den bequemeren Weg durch die kalten Stellen des Apparates, und die katalytische Umsetzung geht dadurch zurück. The enlarged contact apparatus have the supernatant that at Occurring uneven spread of the contact mass increases the temperatures individual points of the apparatus are different. This causes disturbances in the uniform gas flow. The gases are looking for the more convenient route through the cold ones Set the apparatus, and the catalytic conversion goes back.
Die Störungen beim Gasdurchtritt werden dadurch vermieden, daß zwischen mehreren übereinanderliegenden Siebböden in an sich bekannter Weise ein geschlossener Boden, der am besten ebenfalls aus Gußeisen besteht und aus Segmenten zusammengesetzt ist, e>ingelegt wird. Diese Vollsegmente haben in der Mitte je eine Durchtrittsöffnung. Dadurch werden die Gase beim Durchtritt in gewissen Abständen wieder zusammengezogen und gut durchmischt von Abteilung zu Abteilung geführt, wodurch - die besterreichbare Umsetzung erzielt wird. The disturbances in the passage of gas are avoided by the fact that between several superimposed sieve trays in a known manner a closed Floor, which is best also made of cast iron and composed of segments is, e> is inserted. These full segments each have a passage opening in the middle. As a result, the gases are drawn together again at certain intervals when they pass through and well mixed from department to department, whereby - the most accessible Implementation is achieved.
Gemäß der vorliegenden Erfindung werden nun die Gase von oben durch ein Mittelrohr auf den Boden des Apparates geführt. Durch dieses Mittelrohr-wird eine gute strahlenförmige Verteilung von der Mitte aus unter die. Siebböden erreicht. Außerdem hat ein derartiges Rohr den Vorteil, daß es die Vorwärmung der eintretenden Gase ermöglicht. According to the present invention, the gases are now through from above a central tube led to the bottom of the apparatus. Through this central tube becomes a good radial distribution from the center under the. Sieve trays reached. In addition, such a tube has the advantage that it preheats the incoming Gases made possible.
Der Austritt der Gase geschieht an der Decke des Apparates durch eine ringförmige, das Mittelrohr umgebende Öffnung, wodurch wiederum ein gleichmäßiges strahlenförmiges Zusammenziehen der Gase aus dem ganzen Apparatquerschnitt erzielt wird.The gases exit through a on the ceiling of the apparatus annular opening surrounding the central tube, which in turn creates a uniform opening Radial contraction of the gases achieved from the entire cross-section of the apparatus will.
Die Anordnung des Ein- und Austrittes sowie der zwischengelegten Lochplatten bewirkt, daß auch in großen Apparaten die durch den Prozeß auftretenden Temperaturen ganz gleichmäßig auf den Inhalt des Apparates verteilt werden, wodurch die beste Wirkung für das Verfahren gewährleistet wird. The arrangement of the entry and exit as well as the intermediate Perforated plates have the effect that even in large apparatus the resulting from the process Temperatures are evenly distributed over the contents of the apparatus, whereby the best effect for the procedure is guaranteed.
Apparate nach der vorliegenden Erfindung können naturgemäß auch für jedes andere katalytische Verfahren benutzt werden. Man kann den Apparaten einen runden, viereckigen oder jeden anderen Querschnitt geben. Apparatus according to the present invention can of course also for any other catalytic process can be used. You can use the machines round, square or any other cross-section.
Die Zeichnung zeigt eine Ausführungsform der Erfindung, und zwar ist Abb. I ein senkrechter Schnitt durch den Apparat und Abb. 2 ein Querschnitt nach der Linie a-b von Abb. I. The drawing shows an embodiment of the invention, namely Fig. I is a vertical section through the apparatus and Fig. 2 is a cross section according to the line a-b of Fig. I.
