Description

Hochdruckgefäße oder Hochdruckrohre, insbesondere mit eingebauten Rohrbündeln, in denen chemische Reaktionen bei hohen Temperaturen vor sich gehen oder durch welche heiße Gase oder Flüssigkeiten unter Druck geleitet werden, müssen im Innern isoliert werden, um die dem hohen Druck ausgesetzte Wand vor den hohen Temperaturen zu schützen. Es ist in solchen Fällen üblich, die Isolierung auf der Innenseite der Hochdruckgefäße oder -rohre einzumauern oder auf den in die Hochdruckgefäße gehörenden Einbauteilen, wie z. B. High pressure vessels or high pressure pipes, especially those with built-in ones Tube bundles in which chemical reactions take place at high temperatures or through which hot gases or liquids are passed under pressure be insulated inside, around the wall exposed to the high pressure from the high one Protect temperatures. It is common in such cases to place the insulation on the Walling up the inside of the high-pressure vessels or pipes or on the inside of the high-pressure vessels associated built-in parts, such as B.

Röhrenbündeln, fest aufzumauern, ehe diese Einbauteile, z. B. das Röhrenbündel, in den Hochdruckraum geschoben werden.Bundles of tubes to be walled up firmly before these built-in parts, e.g. B. that Tube bundle to be pushed into the high pressure chamber.

Bei der Durchführung von Reparaturen, z. B. an derartigen Röhrenbündeln, muß die Isolierschicht zerschlagen werden, um an die auszubessernden Stellen heranzukommen, was meistens sehr umständlich ist und lange Reparaturzeiten, Kosten für neues Isoliermaterial und entsprechend lange Außerbetriebsetzung der Apparatur bedingt. When carrying out repairs, e.g. B. on such tube bundles, the insulating layer has to be smashed in order to get to the areas to be repaired, which is usually very cumbersome and long repair times, costs for new insulation material and a correspondingly long shutdown of the equipment.

Es wurde nun gefunden, daß sich die geschilderten Nachteile vermeiden und erhebliche Produktionssteigerungen infolge Abkürzung der Reparaturzeiten erzielen lassen, wenn die Isolierung aus längs oder bzw. und quer unterteilten, auf der Innenwand des I Hochdruckgefäßes anliegenden Schalen besteht, die aus Isolations- und Versteifungsmaterial hergestellt und ohne Zerstörung herausziehbar sind und damit das Isolationsmaterial erhalten bleiben kann. It has now been found that the disadvantages outlined are avoided and achieve significant increases in production by shortening repair times leave, if the insulation is divided lengthways or and crossways, on the inner wall The shells adjacent to the I high-pressure vessel are made of insulation and stiffening material are produced and can be pulled out without being destroyed, and thus the insulation material can be preserved.

Die Kosten für die Anschaffung derartiger Isolierschalen entstehen nur einmal; sie geben zudem, gegebenenfalls nach Verschraubung, etwaigen Einbauten erhöhte Steifheit und damit einen besseren Halt. Die Isolierschalen können Hohlschalen aus Blech sein, die mit Isoliermasse gefüllt sind; man kann aber auch die Schalen ganz aus keramischen oder hydraulisch abbindenden Stoffen oder aus hãrtenden Kitten herstellen. The costs for purchasing such insulating shells arise once only; they also provide any built-in components, if necessary after screwing increased stiffness and thus a better hold. The insulating shells can be hollow shells be made of sheet metal filled with insulating compound; but you can also use the bowls made entirely of ceramic or hydraulically setting materials or of hardening putty produce.

In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel näher erläutert: Als Beispiel für einen Einbauteil wurde das Röhrenbündel R gewählt. H ist der Hochdruckmantel für beispielsweise 200 at Druck, J ist die Isoliermasse, z. B. The invention is illustrated in more detail in the drawing using an exemplary embodiment explained: The tube bundle R was chosen as an example for a built-in part. H is the high pressure jacket for e.g. 200 at pressure, J is the insulating compound, z. B.

Schamotte, die sich in den Blechschalen B befindet, die zu dem Isoliermantel zusammengesetzt sind.Fireclay, which is located in the sheet metal shells B, leading to the insulating jacket are composed.

Die Blechschalen sind unter sich durch Flanschverbindungen F verschraubt, die dem Ganzen eine Versteifung geben. Zur weiteren Versteifung können noch Rippen K vorgesehen sein. Die mit Isoliermasse gefüllten Blechschalen werden vor dem Einbringen des Bündels in den Hochdruckraum um das Bündel R gelegt und verschraubt und dann in den Mantel H geschoben. Bei Reparaturen wird das Ganze zerstörungsfrei aus dem Mantel gezogen und werden die Isolierschalenteile abgenommen.The sheet metal shells are screwed together with flange connections F, which give the whole thing a stiffening. Ribs can be used for further stiffening K may be provided. The sheet metal shells filled with insulating compound are placed before they are introduced of the bundle in the high pressure space around the bundle R and screwed and then pushed into the coat H. During repairs, the whole thing becomes non-destructive from the Jacket pulled and the insulating shell parts are removed.

Diese können dann ohne umständliche Isolationsarbeiten wieder verwendet werden.These can then be used again without cumbersome insulation work will.

PATENTANSPRVCHE I. Isolationsschutz fürWandungen von Hochdruckgefäßen oder -rohren, insbesondere mit eingebauten Rohrbündeln, bestehend aus längs oder bzw. und quer unterteilten, auf der Innenwand anliegenden, aus Isolations- und Versteifungsmaterial hergestellten Schalen, die ohne Beschädigung der Isolation herausziehbar und damit wieder verwendbar sind. PATENT CLAIM I. Insulation protection for walls of high pressure vessels or tubes, in particular with built-in tube bundles, consisting of longitudinal or or and transversely divided, lying on the inner wall, made of insulation and stiffening material Manufactured shells that can be pulled out without damaging the insulation and thus are reusable.
