Description
Vorrichtung zum Rektifizieren von Gasgemischen oder zum Waschen von Gasen oder Gasgemischen Vorrichtungen zum Rektifizieren von Gasgemischen oder zum Waschen von Gasen oder Gasgemischen bestehen in der Regel aus Hohlsäulen, die mit Einbauten versehen sind, welche eine äußerst feine Verteilung des Gases in der Flüssigkeit bewirken sollen, so daß ein möglichst vollkommener .Stoffaustausch zustande kommen kann. Hierfür werden in einfachen Fällen Füllkörpersäulen angewendet, die bei gewöhnlichen Waschverfahren häufig genügell. t;iir Zerlegullgsapl)arate werden dagegen meistens Säulen mit Rektifizierböden angewendet, die z. B. als Glocken- oder Siebböden ausgebildet werden.Device for rectifying gas mixtures or for washing Gases or gas mixtures Devices for rectifying gas mixtures or for Washing gases or gas mixtures usually consist of hollow columns with Internals are provided, which allow an extremely fine distribution of the gas in the liquid should cause, so that an exchange of substances as perfect as possible comes about can. For this purpose, in simple cases, packed columns are used that in ordinary Washing methods are often sufficient. t; iir Zerlegullgsapl) arates, on the other hand, are mostly Columns with rectifying floors applied, the z. B. designed as bubble trays or sieve trays will.
Die Erfindung zeigt eine neue Anordnung für Austauschsäulen, die bei den verschiedensten Arten der Gasbehandlung Anwendung finden kann und darin besteht, daß in den \Vasch- oder Rektifiziersäulen seiikrecht und vorzugsweise in gleichmäßigen Abständen Siebe oder gleichwertige Konstruktionsteile angeordnet sind, z. B. Drahtgewebe oder Lochbleche. mit zwischen ihnen liegenden Lenkflächen. wobei entweder die Lenkflächen oder die Siebe oder beide gewellt sind und durch die Höhe der Wellen der Abstand zwischen Sieben und Lenkflächen bestimmt ist. The invention shows a new arrangement for exchange columns that can be used in the most varied of types of gas treatment and therein is that in the \ Vasch- or rectifying columns are right and preferably in sieves or equivalent construction parts are arranged at regular intervals, z. B. wire mesh or perforated sheets. with steering surfaces lying between them. whereby either the steering surfaces or the sieves or both are corrugated and by the height of the waves the distance between screens and steering surfaces is determined.
Das Prinzip der Erfindung sei an ITaiid der Abb. 1 erläutert. Die senkrechten Siebe S werden durch die gewellten Lenkflächen L in einem bestimmten .4>bstand gehalten. Ein System solcher Einbauten ist in einer Säule von beispielsweise rechteckigem oder quadratischem Querschnitt untergebracht. Das Gas' bewegt sich zwischen den I,enkflächen und durch die Siebe hindurch in Pfeilrichtung von unten nach oben. Die Flüssigkeit wird wie üblich ollen aufgegeben und sickert der Gasströmung entgegen durch die Siebe von ollen nach unten, wobei sie sich an den Stellen, wo die Lenkflächen die Siebbleche berühren, etwas anstaut. The principle of the invention is explained on the basis of FIG. 1. the vertical sieves S are through the corrugated steering surfaces L in a certain .4> held up. A system of such internals is in a column of for example rectangular or square cross-section. The gas' moves between the I, enkflächen and through the sieves in the direction of the arrow from bottom to top. The liquid is poured in as usual and seeps against the gas flow through the sieves from ollen down, where they are in the places where the steering surfaces touch the sieve trays, something backs up.
Außerdem benetzt sich das Sieb auch oberhalb dieser Stellen mit der Flüssigkeit die einen nahezu geschlossenen Film auf den Siehen bildet. Dieser Film wird durch das aufsteigende Gas ständig durchdrungen, zerrissen und durch die nachsickernde Flüssigkeit neu gebildet. Die Nufstauungen der Flüssigkeit an den Berührungsstellen der Siebe und Lenkflächen werden von der Gasströmung getragen und stellen sich derart ein, daß bei starker Gasströmung ein höherer Strömungswiderstand besteht als bei schwacher Gasströmung. Es stellt sich also zwischen Flüssigkeit und Gas in ähnlicher Weise ein Strömungsgleichgewicht ein, wie dies bei Rektifizierböden bereits bekannt ist. Der Vorteil der Änordnung nach der Erfindung ist jedoch der, daß der Strömungswiderstand bei sonst gleich gutem Stoffaustausch geringer ist als bei Rektifizierböden, bzw. daß bei gleichem Strömungswiderstand der Stoffaustausch besser ist.In addition, the sieve wets itself with the above these points Liquid that forms an almost closed film on the screen. This movie is constantly penetrated and torn by the rising gas and by the seeping in Liquid newly formed. The congestion of the liquid at the points of contact the sieves and steering surfaces are carried by the gas flow and are positioned in this way one that with a strong gas flow there is a higher flow resistance than with weak gas flow. So there is a similar position between liquid and gas Establish a flow equilibrium, as is already known with rectifying trays is. The advantage of the arrangement according to the invention, however, is that the flow resistance with otherwise equally good mass transfer is lower than with rectifying trays, or that with the same flow resistance the mass transfer is better.
Lenkflächen und Siebe können an den Berührungsstellen verlötet, verschweißt, z. B. Punktschweißung, oder vernietet werden. In den weitaus meisten Fällen genügt es aller, Siebe und Lenkflächen federnd aneinanderzudrücken, was vermöge der Federwirkung der Bleche bequem durchführbar ist. Es genügt dabei, die Siebe und Lenkflächen in die Säulen hineinzuschieben und oben und unten zu befestigen oder nur unten durch Roste od. dgl. zu halten. Die Maschenweite der Gewebe oder der Lochdurchmesser der Siebe ist iihnlich zu wählen wie bei Siebboden, also in der Größenordnung von 0,5 bis zu einigen Millimetern. Steering surfaces and screens can be soldered, welded, z. B. spot welding, or riveted. In the vast majority of cases it is sufficient It all resiliently press sieves and steering surfaces against each other, which is by virtue of the spring action the sheets can be carried out easily. It is sufficient to put the sieves and steering surfaces in to push the pillars in and fasten them at the top and bottom or only through the bottom To hold grids or the like. The mesh size of the fabric or the hole diameter of the Sieves should be selected similarly to sieve bottoms, i.e. in the order of 0.5 up to a few millimeters.
Die Siebe, Drahtgewcbe oder Lochbleche brauchen nicht gleichmaschig zu sein. Es kann vielmehr zweckmäßig sein, die Lochgröße oder Maschenweite dort, wo die Flüssigkeitsstauungen erfolgen. größer zu wählen als weiter oberhalb der Berührungsstellen zwischen den Lenkflächen und den Sieben. Schließlich ist es bisweilen zweckmäßig. z. 13. bei Flüssigkeiten höherer Zähigkeit die Drähte tler Gewel>e schräg gegen die Iforizontale geneigt anzuordnen.The sieves, wire mesh or perforated sheets do not need to be uniformly meshed to be. Rather, it may be useful to determine the hole size or mesh size there, where the fluid stagnation occurs. to be chosen larger than further above the Points of contact between the steering surfaces and the sieves. After all, it is at times expedient. z. 13. In the case of liquids of higher viscosity, the wires tler Gewel> e to be arranged at an angle to the ifo-zontal.
Bei Konstruktionen gemäß der Erfindung sind die verschiedenartigsten Formgebungen möglich, von denen eine Auswahl nachstehend als Beispiele an Hand der Abb. I bis 7 erläutert wird. The constructions according to the invention are very diverse Shapes possible, a selection of which are given below as examples using the Fig. I to 7 will be explained.
Die Abb. 2 und 3 zeigen eine liesoiidcre Art der Wellung der Lenkflächen. Die zusätzlichen kleinen Wellungen verhindern ein zu rasches Ablaufen der Flüssigkeit und ermöglichen es, eine kleine Flüssigkeitsmenge auch bei Betriebsunterbrechungen zu halten. Figs. 2 and 3 show a liesoiidcre type of corrugation of the steering surfaces. The additional small corrugations prevent the liquid from draining off too quickly and make it possible to use a small amount of liquid even during business interruptions to keep.
Die Abb. 4 und 5 zeigen die Möglichkeit. sowohl die Lenkflächen wie auch die Siebe zu wellen, wodurch der elastische Druck zwischen beiden verbessert wird. Fig. 4 and 5 show the possibility. both the steering surfaces as also to corrugate the screens, which improves the elastic pressure between the two will.
Abb. 6 zeigt die Befestigung der Siebe und Lenkflächen an den Wänden einer rechteckigen Säule mit Hilfe von Profilleisten l'. Es lassen sich jedoch auch runde Säulen (Abb. 7) herstellen, indem man die entstehenden hohlen Zwischenräume s durch Blechwinkel in der ganzen Höhe der Säulen gasdicht abschließt. Fig. 6 shows the attachment of the screens and steering surfaces to the walls a rectangular column with the help of profiled strips l '. However, it can also be Make round pillars (Fig. 7) by removing the resulting hollow spaces s is sealed gas-tight by sheet metal angles over the entire height of the columns.
