Description
Es ist bekannt, bei kleineren Behältern. den oberen Rand dadurch zu versteifen, daß er zu einem Rohrring umgebördelt wird. Jedoch kommt diese Art einer Versteifung für Absorptionstürme nicht in Betracht. It is known for smaller containers. the top edge through it to stiffen that it is flanged into a pipe ring. However, this species comes stiffening for absorption towers is out of the question.
Absorptionstürme, die z. B. bei der Herstellung von Salpetersäure verwendet werden und in denen aufsteigende Gase mit abwärts rieselnden Flüssigkeiten in Berührung gebracht werden, bestehen in der Regel aus einem zylindrischen Behälter. der oben mit einem gewölbten Deckel verschlossen ist. Absorption towers, e.g. B. in the production of nitric acid are used and in which rising gases are mixed with downward flowing liquids are brought into contact, usually consist of a cylindrical container. which is closed at the top with a domed lid.
Der zylindrische Behältermantel ist an seinem oberen Ende mittels eines aus korrosionsbeständigem Stahl bestehenden Winkelringes mit einem der Deckelwölbung angepaßten Winkel und eines an der Außenseite des Winkefringes angebrachten Ringes aus normalem Stahl mit U- oder I-Profil versteift. Diese Versteifung hat den Nachteil, daß die Herstellung des korrosionsbeständigen Winkelringes teuer ist. Außerdem hat es sich gezeigt, daß der U-Eisenring durch die korrodierenden Gase, die in der Nähe derartiger Anlagen unvermeidbar sind, sowie die beim Zusammentreffen der Gase mit Feuchtigkeit sich bildenden aggressiven Flüssigkeiten angegriffen und zerstört bzw. geschwächt wird. Diese Nachteile werden nach der Erfindung vermieden.The cylindrical container jacket is at its upper end by means an angle ring made of corrosion-resistant steel with one of the lid bulges adapted angle and a ring attached to the outside of the bevel ring Made of normal steel reinforced with a U or I profile. This stiffening has the disadvantage that the production of the corrosion-resistant angle ring is expensive. Also has it was shown that the U-iron ring was caused by the corrosive gases that were in the vicinity such systems are unavoidable, as well as when the gases meet Aggressive liquids formed by moisture are attacked and destroyed or is weakened. These disadvantages are avoided according to the invention.
Der Gegenstand der Erfindung besteht darin, daß die Verbindung zwischen Behältermantel und Deckel aus einem an beiden Teilen angeschweißten Rohrring besteht. The object of the invention is that the connection between The container jacket and cover consist of a pipe ring welded to both parts.
In der Zeichnung ist eine Ausführung nach der Erfindung dargestellt. und zwar zeigt Fig. I den oberen Teil eines Absorptionsturmes teils in Ansicht, teils im Schnitt und Fig. 2 einen senkrechten Schnitt durch die Rohrringverbindung im größeren Maßstab. In the drawing, an embodiment according to the invention is shown. namely Fig. I shows the upper part of an absorption tower partly in view, partly in section and FIG. 2 shows a vertical section through the pipe ring connection on a larger scale.
Der in Fig. I und 2 dargestellte Teil eines Absorptionsturmes besteht aus dem zylindrischen Behältermantel I und dem gewölbten Deckel 2. Die Verbindung zwischen diesen wird durch den. Rohrring 3 bewirkt, der aus korrosionsbeständigem Werkstoff besteht. Wie insbesondere aus Fig. 2 ersichtlich ist, ist der Rohrring 3 bei der dargestellten Ausführungsform an der Innenseite des Behältermantels I angeordnet und bildet den Übergang zwischen dem Behältermantel I und dem Deckel 2. The part shown in Fig. I and 2 consists of an absorption tower from the cylindrical container jacket I and the domed lid 2. The connection between these is through the. Pipe ring 3 causes the corrosion-resistant Material. As can be seen in particular from FIG. 2, the tubular ring is 3 in the illustrated embodiment on the inside of the container shell I. arranged and forms the transition between the container shell I and the lid 2.
Der äußere Durchmesser des Rohrringes 3 ist etwas größer als der lichte Durchmesser des Behältermantels I, so daß letzterer den Rohrring 3 tangential oder annähernd tangential berührt. Die Verbindung des Rohrringes 3 mit dem Behältermantel 1 und dem vorzugsweise ebenfalls tangential angeordneten Deckel 2 erfolgt durch Schweißen.The outer diameter of the pipe ring 3 is slightly larger than the clear Diameter of the container shell I, so that the latter the pipe ring 3 tangential or almost tangentially touched. The connection of the pipe ring 3 with the container jacket 1 and the preferably also tangentially arranged cover 2 takes place through Welding.
Der Deckel 2 ist durch radial angeordnete und mit ihm und dem Rohrring verbundene, vorzugsweise verschweißte Sparren 4 mit Winkelprofil.versteift.The cover 2 is arranged radially and with it and the tubular ring connected, preferably welded rafters 4 stiffened with angled profile.
Die Verbindung nach der Erfindung hat vor der bekannten Randversteifung durch einen Winkelring mit Verstärkung durch einen Ring aus U- oder I-Eisen. den. Vorteil, daß der korrodierenden Einflüssen ausgesetzte äußere Ring aus U- oder I-Eisen fortfällt. Außerdem weist der Rohrring in allen Richtungen gleiche Widerstandsfähigkeit gegen auftretende Biegebeanspruchungen auf, während der aus U- oder I-Profilen hergestellte Verstärkungsring gegen nicht radiale Beanspruchungen weniger widerstandsfähig ist. Die Möglichkeit, den Deckel tangential am Rohrring zu befestigen, hat den Vorteil, daß Anpassungsschwiengkeiten bei der Montage vermieden werden. The connection according to the invention has before the known edge stiffening by an angle ring with reinforcement by a ring made of U or I iron. the. The advantage that the outer ring is made of U or I iron, which is exposed to corrosive influences no longer applies. In addition, the tubular ring shows the same resistance in all directions against occurring bending stresses, while the one made from U- or I-profiles Reinforcement ring is less resistant to non-radial loads. The possibility of attaching the cover tangentially to the pipe ring has the advantage of that adjustment difficulties during assembly are avoided.
