Description

Die Erfindung betrifft eine an der Innenwand angeordnete Isolation von Behältern, die auf der Außenwand einer normalen atmosphärischen oder höheren Temperatur ausgesetzt sind und der Aufnahme von tiefsiedenden Flüssiggasen dienen.The invention relates to one arranged on the inner wall Isolation of containers that are on the outer wall of a normal atmospheric or higher Are exposed to temperature and are used to absorb low-boiling liquefied gases.

Um Wärmeübertragung von der Umgebung auf die Flüssigkeit zu vermeiden oder herabzusetzen, ist es üblich, den Behälter außen und in gewissen Fällen auch innen zu isolieren. Falls es sich um sehr niedrige Temperaturen handelt, werden auf der Behälterinnenseite angeordnete Isolationswerkstoffe leicht brüchig, und das Isolationsvermögen wird durch Bildung von Rissen oder Sprüngen im Material herabgesetzt.In order to avoid or reduce heat transfer from the environment to the liquid, it is It is customary to insulate the container on the outside and, in certain cases, on the inside. If it is very low Temperatures, insulation materials arranged on the inside of the container are easily brittle, and the insulation capacity is reduced by the formation of cracks or cracks in the material.

Die Erfindung basiert darauf, daß die Wärmeübertragung durch Gase (Dämpfe) unbedeutend ist. Es wurde daher als Isolation die in einem porösen, auf der Behälterinnenfläche angeordneten Werkstoff geschaffene Gasschicht verwendet.The invention is based on the fact that heat transfer through gases (vapors) is insignificant. It The insulation was therefore created in a porous material arranged on the inner surface of the container Gas layer used.

Gemäß der Erfindung werden an den Wänden des Behälters Lamellen angebracht, vorzugsweise senkrecht zu der Wand und in verhältnismäßig kleinem Abstand voneinander.According to the invention, slats are attached to the walls of the container, preferably vertically to the wall and at a relatively small distance from each other.

Der Raum zwischen den Lamellen ist in eine Anzahl von Einzelräumen oder Poren aufgeteilt, und in den Poren wird an der gegen die Außenwand anliegenden Seite eine Temperatur herrschen, die oberhalb des Siedepunkts der Flüssigkeit liegt, und die Flüssigkeit wird hierdurch in Gasform übergehen. Auf der zur Flüssigkeit hingekehrten Seite der Poren wird die Flüssigkeit eine Temperatur haben, die der Kondensationstemperatur der Gase entspricht, und die Temperaturkurve wird ungefähr geradlinig von der Wand zur Flüssigkeit fallen. Die Breite der Lamellen wird so bemessen, daß die Poren nahezu völlig mit Gas gefüllt werden und nur eine unerhebliche Flüssigkeitsmenge aufnehmen.The space between the lamellae is divided into a number of individual spaces or pores, and into the pores will have a temperature on the side lying against the outer wall that is above the boiling point of the liquid, and the liquid will thereby pass into gaseous form. On the side of the pores facing the liquid, the liquid will have a temperature that the Corresponds to the condensation temperature of the gases, and the temperature curve is approximately straight from the Wall falling to the liquid. The width of the lamellae is dimensioned so that the pores are almost completely with Gas are filled and only absorb an insignificant amount of liquid.

Der Abstand zwischen den Lamellen, d. h. die Weite der Poren, muß so klein sein, daß Konvektionsströmungen nicht entstehen können, welche gegebenenfalls die Wärmeübertragung von der Wand zur Flüssigkeit steigern würden. Konvektionsströmen kann übrigens auch durch Einlegen eines Füllmaterials in die Poren entgegengewirkt werden.The distance between the slats, i.e. H. the width of the pores must be so small that convection currents can not arise, which possibly the heat transfer from the wall to Would increase fluidity. Incidentally, convection currents can also be created by inserting a filler material in the pores are counteracted.

Vorkehrungen müssen auch getroffen werden, um einen Konvektionsstrom entlang der Wandfläche zu vermeiden. Dies kann in einfachster Weise durch Befestigung der Lamellen an der Wand mittels einer Schicht von klebendem Material geschehen, welches somit jede Pore an der Wandseite schließt. Auch können Gruppen von nebeneinanderliegenden Poren miteinander verbunden sein.Precautions must also be taken to prevent convection currents along the wall surface avoid. This can be done in the simplest way by attaching the slats to the wall by means of a Layer of adhesive material happen, which thus closes every pore on the wall side. Even groups of adjacent pores can be connected to one another.

Als Material für die Lamellen können Metall, Kunstharz, Papier oder ein gewebtes Material benutzt werden. Um die Wärmeübertragung durch die Lamel-An der Innenwand angeordnete Isolation von Behältern für tiefsiedende FlüssiggaseMetal, synthetic resin, paper or a woven material can be used as the material for the lamellas will.

len selbst herabzusetzen, haben diese sehr geringe Wandstärke.len themselves have this very thin wall thickness.

Die Lamellen selbst sollten außerdem eine dunkle und nicht glatte Oberfläche haben, um möglichst wenig Wärme zu reflektieren.The lamellas themselves should also have a dark and non-smooth surface in order to minimize the risk of damage Reflect heat.

Es wird auch von Vorteil sein, für die Lamellen ein wenig benetzbares Material zu verwenden, um ein Kriechen der Flüssigkeit entlang der Lamellenwand zur Behälteraußenwand hin zu vermeiden.It will also be an advantage to use a little wettable material for the lamellas in order to create a To avoid the liquid creeping along the lamellar wall towards the outer wall of the container.

Die zwischen den Lamellen gebildeten Poren können jede beliebige -Querschnittsform haben, z. B. eine kreisförmige, viereckige, sechseckige usw., was durch entsprechende Formung der Lamellen erzielt wird.The pores formed between the lamellae can have any cross-sectional shape, e.g. Legs circular, square, hexagonal, etc., which is achieved by appropriate shaping of the slats.

Das vorliegende Isolationsverfahren bringt beim Transport von flüssigem Methan in großen Behältern auch einen anderen Vorteil mit sich. Falls nämlich der Behälter Stößen ausgesetzt wird, also die Gefahr besteht, daß das Flüssigkeitsgas gefährliche Beanspruchungen der Behälterwände bewirkt, kann die in den Poren befindliche Gasmenge auf die Flüssigkeit eine Pufferwirkung ausüben.The present isolation method brings about the transportation of liquid methane in large containers also has another advantage with it. If the container is exposed to shocks, i.e. there is a risk of that the liquid gas causes dangerous stresses on the container walls, the in the The amount of gas in the pores has a buffering effect on the liquid.

Um das Eindringen von Flüssigkeit weiter zu dämpfen, können die Poren mit Verengungen versehen sein.In order to further dampen the penetration of liquid, the pores can be provided with constrictions be.

Die Wand des Behälters ist mit 1 und die Lamellen sind mit 2 bezeichnet. Bei der Ausführung nach Fig. 2 sind die Lamellen wellenförmig ausgebildet und so miteinander verbunden, daß zwischen den Lamellen Poren 4 mit kreisförmigem Querschnitt gebildet werden. Außerdem werden Poren 4 zwischen Nachbarlamellen gebildet. In der Ausführungsform nach Fig. 3 sind die Lamellen zickzackförmig gebogen, so daß der Querschnitt der Poren quadratisch wird. Man kann die Querschnittsform der Poren variieren, z. B. sechseckig gestalten, so daß die Lamellen entlang langen Flächen miteinander verbunden werden.The wall of the container is denoted by 1 and the lamellas are denoted by 2. In the embodiment according to FIG. 2 the slats are wave-shaped and connected to each other so that between the slats Pores 4 are formed with a circular cross-section. In addition, there are pores 4 between neighboring lamellae educated. In the embodiment according to FIG. 3, the slats are bent in a zigzag shape, see above that the cross-section of the pores becomes square. The cross-sectional shape of the pores can be varied, e.g. B. Make it hexagonal so that the slats are joined together along long surfaces.

Mit Rücksicht auf die Montage der Isolation auf der Wand ist es vorteilhaft, die Isolation in Einheiten von passender Größe herzustellen. Diese Einheiten können quadratische, rechteckige oder andere zweckmäßige Formen haben. In Fig. 4 ist eine Einheit mit sechseckiger Form gezeigt, wo 5 einen die Lamellen umschließenden Rahmen bezeichnet.With regard to the installation of the insulation on the wall, it is advantageous to use the insulation in units of suitable size. These units can be square, rectangular, or other convenient ones Have shapes. In Fig. 4 a unit is shown with a hexagonal shape, where 5 one of the slats enclosing frame called.

Um Konvektionsströme zu hindern, wird es bei einer senkrechten Wand zweckmäßig sein, die Lamellen anzuordnen, so daß die Längsachsen der Poren, wie in Fig. 5 gezeigt, schräg nach unten gerichtet sind.In order to prevent convection currents, it will be advisable to use the slats in the case of a vertical wall to be arranged so that the longitudinal axes of the pores, as shown in Fig. 5, are directed obliquely downward.
