Description

Lagerbehfllter für flüssige und/oder feste chemische Fällungsmittel  Storage containers for liquid and / or solid chemical precipitants

Die Erfindung betrifft einen Lagerbehälter für flüssige und/oder feste chemische Fällungsmittel, der wenigstens an der Innenseite seiner Wandungen aus gegen diese resistentem Material besteht. The invention relates to a storage container for liquid and / or solid chemical precipitants, which consists at least on the inside of its walls from material resistant to these.

Es sind Lagerbehälter dieser Art bekannt, die aus hochwertigen Metallegierungen bestehen, da solche Storage containers of this type are known, which consist of high quality metal alloys, as such

Legierungen die Eigenschaft aufweisen, gegen chemische Fällungsmittel resistent zu sein und darüberhinaus die nötige Festigkeit für den Bau von Behältern haben.  Alloys have the property of being resistant to chemical precipitants and also have the necessary strength for the construction of containers.

Diese Art von Behältern ist relativ teuer und auch schwer an die oft vorgegebene Geometrie am Aufstellungsort anpaβbar.  This type of container is relatively expensive and difficult to adapt to the often specified geometry at the installation site.

Daher ist man dazu übergegangen auf festem Untergrund resistente Kunststoffschichten mit innenliegenden Sperrschichten aus Metall, meist Aluminium, aufzubringen, Die Beschädigunggefahr der Kunststoffschicht ist dabei sehr groß und es hat sich gezeigt, daß die Aluminiumsperrschicht den Fällungsmitteln nicht lange widersteht.  Therefore, it has gone over to applying resistant plastic layers with internal barrier layers made of metal, usually aluminum, on a solid surface. The risk of damage to the plastic layer is very high and it has been shown that the aluminum barrier layer does not withstand the precipitants for long.

Aus Sicherheitsgründen war es daher erforderlich It was therefore necessary for security reasons

geworden, die Behälterwände doppelwandig auszuführen, um bei einer Leckage einerseits die Flüssigkeit nicht ins Erdreich versickern zu lassen und andererseits gleichzeitig die Möglichkeit zu haben, diese Leckage mit become double-walled in order to prevent the liquid from seeping into the ground if there is a leak, and at the same time to have the possibility of having this leak

Meßgeräten zu erfassen. Measuring devices.

Solche bekannten Lagerbehfllter bestehen aus einem  Such known storage containers consist of a

festen Untergrund, meist Beton, auf dem eine solid surface, mostly concrete, on one

glasfaserverstärkte Kunststoffschicht auf Abstands- heltern aus Aluminiumrippen aufgebracht ist. glass fiber reinforced plastic layer on spacer heltern is applied from aluminum ribs.

Nachteilig ist hier einerseits die kostspielige und zeitaufendige Herstellung und andererseits, daß Beton nicht als resistent anzusehen ist und im Leckagefall dem aggressiven Medium nicht widersteht.  Disadvantages here are, on the one hand, the costly and time-consuming production and, on the other hand, that concrete is not to be regarded as resistant and does not withstand the aggressive medium in the event of a leak.

Aufgabe der Erfindung war es daher, Lagerbehälter zu schaffen, die einfach und billig in der Herstellung sind, an die oft vorgegebene Geometrie leicht anpaßbar sind und die darüberhinaus dem ständig steigendem Sicherheitsbedürfnis Rechnung tragen. The object of the invention was therefore to provide storage containers which are simple and inexpensive to manufacture, to which the often predetermined geometry can be easily adapted and which moreover take account of the constantly increasing need for security.

Diese Aufgabe wird dadurch gelöst, daß das Material der Wandungen des Lagerbehälters wenigstens teilweise aus einer Niederdruck-Polyethylenschicht besteht und daß auf dieser Schicht eine vorzugsweise einseitig mit Noppen versehene weitere Polyethylenschicht noppenseitig aufliegend, vorgesehen ist. This object is achieved in that the material of the walls of the storage container consists at least partially of a low-pressure polyethylene layer and that on this layer a further polyethylene layer, preferably provided with knobs on one side, is provided lying on the knobs side.

Durch die Noppenauflage wird erreicht, daß zwischen zwei Polyethylenschichten auf einfach Weise ein  The pimpled cover ensures that between two polyethylene layers in a simple manner

Hohlraum entsteht, der im Falle der Undichtigkeit der ersten Folie die Leckflüssigkeit einerseits sicher speichert und andererseits die Möglichkeit schafft, die Leckage mit Meßgeräten zu erfassen.  Cavity is created which, in the event of a leak in the first film, on the one hand securely stores the leakage liquid and on the other hand creates the possibility of detecting the leakage using measuring devices.

Die Wandungen, damit ist auch der Boden des Lagerbehälters gemeint, sind gemäß der Weiterbildung der  The walls, which also means the bottom of the storage container, are according to the training of

Erfindung vielfältig gestaltbar.  Invention can be designed in many ways.

Eine spezielle Ausgestaltung gemäß der Erfindung ist darin zu sehen, daß die Wandungen des Lagerbehälters ganz aus Niederdruck-Polyethylen bestehen.  A special embodiment according to the invention can be seen in the fact that the walls of the storage container consist entirely of low-pressure polyethylene.

Zweckmäßigerweise wird weiter vorgeschlagen, daß die Wandungen des Lagerbehälters aus beliebig festem Advantageously, it is further proposed that the walls of the storage container from any solid

Trägermaterial mit einer innenseitig aufliegenden festen Polyethylen-Plattierung besteht. Carrier material with a solid polyethylene cladding lying on the inside.

Um auch den Einsatz flexibler Noppenfolien als To also use flexible pimpled films as

Polyethylenschichten verwenden zu können und trotzdem einen gesicherten Hohlraum zwischen den Schichten zu erhalten, wird zweckmäßig vorgeschlagen, daß die Wandungen des Lagerbehälters aus beliebigem festen Trägermaterial mit einer innenseitig aufliegenden, an der einen freien Seite mit Noppen versehenen To be able to use polyethylene layers and still obtain a secure cavity between the layers, it is expediently proposed that the Walls of the storage container made of any solid support material with an inner one, provided with knobs on one free side

Polyethylenschicht besteht.  Polyethylene layer exists.

Eine weitere Lösung besteht darin, daß die Wandungen des Lagerbehälters aus einem aushärtbaren Trägermaterial mit einer mit Noppen versehenen,noppenseitig aufliegenden Polyethylenschicht besteht, und daß die Noppen in dem aushärtbaren Trägermaterial eingebettet sind. Dem Sicherheitsbedürfnis wird dadurch entsprochen, daß der durch die Noppen der auf den Wandungen des Lagerbehälters aufliegenden weiteren Polyethylenschicht gebildete Hohlraum luftdicht verschlossen und mit einem Vakuumüberwachungsgerflt verbunden ist.  Another solution consists in that the walls of the storage container consist of a hardenable carrier material with a studded polyethylene layer on the knob side, and that the knobs are embedded in the hardenable carrier material. The need for security is met in that the cavity formed by the knobs of the further polyethylene layer resting on the walls of the storage container is hermetically sealed and connected to a vacuum monitoring device.

Die Erfindung wird anhand der gezeichneten Ausführungsbeispiele erläutert.  The invention is explained on the basis of the illustrated exemplary embodiments.
