Abstract

A spherical packing element (1) made of plastic for mass and heat transfer columns has a lattice work casing composed of parallel round bars (6, 7) and lattice bars (8, 9) disposed as meridians. A round bar (4, 5) corresponds to the diameter of the sphere. In order to make the packing element (1) suitable for, and adaptable to, a variety of operating conditions, the packing element (1) consists of two hemispheres (2, 3) mutually connected by ball elements or similar. A second lattice work packing element of smaller diameter can be advantageously inserted in the packing element (1), which can be readily assembled, in order to increase the transfer surface.

Description

Kugelförmiger Füllkörper aus Kunststoff für Stoff- und Wärmeaustauschkolonnen Spherical packing made of plastic for mass and heat exchange columns

Die Erfindung betrifft einen kugelförmigen Füllkörper aus Kunststoff für Stoff- und Wärmeaustauschkolonnen, dessen Mantel aus parallelen Ringstäben und meridian¬ artig verlaufenden Gitterstäben gitterwerkartig auf- gebaut ist, wobei ein Ringstab dem Kugeldurchmesser entspricht.The invention relates to a spherical packing made of plastic for mass and heat exchange columns, the jacket of which is constructed from parallel ring bars and meridian-like bars, with a ring bar corresponding to the ball diameter.

Füllkörper der gattungsgemäßen Art dienen zum Füllen von Stoff und/oder Wärmeaustauschkolonnen, Gaswasch- türmen, zur Bildung von Trockenkörpern u. dgl. Sie bil¬ den eine Fläche für einen Stoffaustausch oder einen Wärmeübergang. Die Füllkörper sollen eine möglichst große Oberfläche bilden, andererseits aber einen sol¬ chen Aufbau haben, daß der Druckverlust möglichst ge- ring ist. Hierfür haben sich die gitterwerkartig auf¬ gebauten kugelförmigen Füllkörper aus Kunststoff als besonders geeignet erwiesen. Die in den Kolonnen u. dgl. von den Füllkörpern gebildete Austauschfläche wird jedoch im wesentlichen durch die Schüttdichte begrenzt. Für eine weitere Erhöhung der Austauschfläche ist es auch bekannt, an die Ringstäbe in das Kugelinnere wei¬ sende stabförmige Nasen anzuformen. Derartige kugelför¬ mige Füllkörper sind in der Regel in sehr aufwendiger Weise aus Kunststoff gespritzt.Packing bodies of the generic type are used to fill material and / or heat exchange columns, gas washing towers, to form dry bodies and. The like. They form an area for a mass transfer or a heat transfer. The fillers should form as large a surface as possible, but on the other hand should have such a structure that the pressure loss is as low as possible. The spherical fillers made of plastic, which are constructed in the form of a latticework, have proven to be particularly suitable for this. The in the columns u. The like. Exchange surface formed by the packing is essentially limited by the bulk density. For a further increase in the exchange area, it is also known to form rod-shaped lugs on the ring rods into the inside of the ball. Such spherical fillers are usually injection molded from plastic in a very complex manner.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde einen kugelförmigen Füllkörper der gattungsgemäßen " - ~In contrast, the invention has for its object a spherical packing of the generic type "- ~

Art derart auszubilden, daß die Füllkörper für ver¬ schiedene Betriebsbedingungen geeignet und anpaßbar sind.Form in such a way that the packing is suitable and adaptable for various operating conditions.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Füllkörper aus zwei Halbkugeln besteht, die durch Kupplungselemente o. dgl. miteinander verbunden sind. Diese Ausbildung hat den wesentlichen Vorteil, daß in den zusammenfügbar ausgebildeten, gitterwerk- artigen Füllkörper ein weiterer gitterwerkartiger Füllkörper kleineren Durchmessers eingelegt werden kann. Hierdurch wird die Austauschfläche wesentlich erhöht. Weiterhin ist auch die Fertigung der beiden gitterwerkartigen Halbkugeln aus Kunststoff durch Spritzen wesentlich einfacher, als bei einem kugel¬ förmigen Füllkörper.This object is achieved according to the invention in that the packing consists of two hemispheres which are connected to one another by coupling elements or the like. This design has the essential advantage that a further lattice-like filler of smaller diameter can be inserted into the lattice-like filler, which can be joined together. This significantly increases the exchange area. Furthermore, the manufacture of the two lattice-like hemispheres from plastic by injection molding is much easier than with a spherical filler.

Vorzugsweise ist jede Halbkugel mit einem dem Kugel- durchmesser entsprechenden Ringstab versehen, an de- nen die Kupplungselemente angeordnet sind. Jede Halb¬ kugel besitzt also zwei äquatoriale Ringstäbe, die zur Kupplung der beiden Halbkugeln gegeneinanderge- legt und mittels der Kupplungselemente miteinander verbunden werden. Eine besonders einfache Fertigung beim Spritzen aus Kunststoff läßt sich dadurch er¬ zielen, daß die dem Kugeldurchmesser entsprechenden Ringstäbe der beiden Halbkugeln durch einen flachen elastischen Steg aus Kunststoff verbunden sind und auf der gegenüberliegenden Seite Kupplungselemente angeordnet sind. Der flache elastische Steg dient gewissermaßen als Scharnier für das Umklappen der beiden Halbkugeln, wobei eine genaue Anlage der beiden äquatorialen Ringstäbe sichergestellt ist, so daß die Kupplungselemente ineinander eingreifen können.Each hemisphere is preferably provided with a ring rod corresponding to the ball diameter, on which the coupling elements are arranged. Each hemisphere therefore has two equatorial ring rods which are placed against one another for coupling the two hemispheres and are connected to one another by means of the coupling elements. A particularly simple manufacture when spraying from plastic can be achieved in that the ring rods of the two hemispheres corresponding to the ball diameter are connected by a flat elastic web made of plastic and coupling elements are arranged on the opposite side. The flat elastic web serves as a hinge for folding the two hemispheres, whereby an exact contact of the two equatorial ring bars is ensured so that the coupling elements can engage with one another.

Zweckmäßig sind die Ringstäbe, deren Durchmesser kleiner als der Kugeldurchmesser ist, mit in das Kugel¬ innere weisenden stabförmigen Nasen versehen. Diese sind derart auszubilden, daß sie die Einlagerung eines Füll¬ körpers kleineren Durchmesser erlauben, wobei sie aber auch in das Innere dieses gitterwerkartigen Füllkörpers kleineren Durchmesser eingreifen können.The ring rods are useful, their diameter is smaller than the ball diameter, provided with rod-shaped lugs pointing into the inside of the ball. These are to be designed in such a way that they allow the storage of a filler body with a smaller diameter, but they can also intervene in the interior of this lattice-like filler body with a smaller diameter.

Die Kupplungselemente können verschiedenartig ausge¬ bildet sein. Beispielsweise können sie aus stiftför- migen Ansätzen und Lochungen bestehen, die einander gegenüberliegend an den dem Kugeldurchmesser entspre¬ chenden Ringstäben der beiden Halbkugeln angeordnet und als Schnappverschluß ausgebildet sind.The coupling elements can be designed in various ways. For example, they can consist of pin-shaped projections and perforations, which are arranged opposite one another on the ring rods of the two hemispheres corresponding to the ball diameter and are designed as a snap lock.

Der kugelförmige Füllkörper 1 ist gitterwerkartig aus¬ gebildet und besteht aus zwei Halbkugeln 2 bzw. 3. Je¬ de Halbkugel 2 bzw. 3 ist mit einem äquatorialen Ring¬ stab 4 bzw. 5 versehen. Weiterhin besitzt jede Halbku- gel 2 bzw. 3 parallele Ringstäbe 6 bzw. 7 und meri¬ dianartig angeordnete Gitterstäbe 8 bzw. 9 Die bei¬ den äquatorialen Ringstäbe 4 und 5 sind, wie insbe¬ sondere die Fig. 2 und 3 zeigen, an ihrem Außenumfang durch einen flachen elastischen Steg 10 verbunden, der aus der gleichen Kunststoffmasse besteht, aus der die beiden Halbkugeln 2,3 gefertigt sind. Auf der ge¬ genüberliegenden Seite sind an dem äquatorialen Ring- stab 4 stiftfδrmige Ansätze 11 angeformt, während in einer spiegelbildlichen Lage dazu der äquatoriale Ringstab 5 der anderen Halbkugel 3 mit entsprechen¬ den Lochungen 12 versehen ist. Diese stiftförmigen Ansätze 11 und Lochungen 12 sind als Schnappver¬ schlüsse ausgebildet. Weiterhin sind beide Halb¬ kugeln 2 bzw. 3 mit Nasen 13 bzw. 14 versehen, die beim Ausführungsbeispiel parallel zur Polachse ver¬ laufen.The spherical filler body 1 is formed like a lattice structure and consists of two hemispheres 2 and 3. Each hemisphere 2 and 3 is provided with an equatorial ring rod 4 and 5, respectively. Furthermore, each hemisphere has 2 or 3 parallel ring bars 6 or 7 and meridian bars arranged 8 or 9. The two equatorial ring bars 4 and 5 are, as shown in particular in FIGS. 2 and 3 its outer periphery connected by a flat elastic web 10, which consists of the same plastic mass from which the two hemispheres 2, 3 are made. On the opposite side of the equatorial ring rod 4 shaped lugs 11, while in a mirror image position the equatorial ring rod 5 of the other hemisphere 3 is provided with corresponding perforations 12. These pin-shaped projections 11 and perforations 12 are designed as snap closures. Furthermore, both hemispheres 2 and 3 are provided with lugs 13 and 14, which in the exemplary embodiment run parallel to the polar axis.

Der Füllkörper 1 wird aus Kunststoff gespritzt, wo¬ bei die beiden Halbkugeln 2 und 3 in der in den Fig. 2 und 3 dargestellten Lage nebeneinanderliegend und zusammenhängend durch den Steg 10 gespritzt werden. Durch Umklappen der beiden Halbkugeln 2 bzw. 3 wird der kugelförmige Füllkörper 1 gebildet, wobei einer¬ seits der Steg 10 als Scharnier dient und anderer¬ seits die stiftförmigen Ansätze 11 und Lochungen 12 als Schnappverschluß zusammenwirken.The filler 1 is injection molded from plastic, with the two hemispheres 2 and 3 being injected side by side and coherently through the web 10 in the position shown in FIGS. 2 and 3. The spherical filler 1 is formed by folding over the two hemispheres 2 and 3, the web 10 serving as a hinge on the one hand and the pin-shaped projections 11 and perforations 12 interacting as a snap closure on the other hand.

Bedarfsweise kann vor dem Zusammenklappen der bei¬ den Halbkugeln 2 und 3 ein gitterwerkartiger Füll¬ körper kleineren Durchmessers eingelegt werden, der nach dem Schnappverschließen innerhalb des gitter- werkartigen Füllkörpers 1 enthalten ist. Hierdurch wird, ohne daß das Füllvolumen in der Stoff- oder Wärmeaustauschkolonne vergrößert wird, eine größere Austauschfläche erzielt. Dieser eingelegte gitter- werkartige Füllkörper kann entweder selbst entspre- chend der Ausführung nach den Fig. 1 bis 3 ausge¬ bildet sein, oder in herkömmlicher Weise, das heißt ohne auseinanderklappbar zu sein. Wird ein zusammen¬ klappbarer Füllkörper eingelegt, kann sogar inner¬ halb dieses eingelegten Füllkörpers wiederum ein Füllkörper eingelegt sein. If necessary, before the two hemispheres 2 and 3 are folded together, a lattice-like filler of smaller diameter can be inserted, which is contained within the lattice-like filler 1 after the snap closure. As a result, a larger exchange area is achieved without increasing the filling volume in the mass or heat exchange column. This inserted lattice-like filler body can either itself be designed in accordance with the embodiment according to FIGS. 1 to 3, or in a conventional manner, that is to say without being able to be unfolded. If a collapsible filler is inserted, a filler can in turn be inserted even within this inserted filler.
