Abstract
Description
Die Erfindung betrifft einen Tank mit innerer und/oder äußerer doppelwandiger
Verkleidung nach dem Oberbegriff des Anspruchs 1.The invention relates to a tank with an inner and / or outer double-walled
Cladding according to the preamble of
Derartige Tankwandungen mit Verkleidung haben den Vorteil einer verbesserten Korrosionsbeständigkeit und erlauben eine Lecküberwachung in der doppelwandigen Verkleidung, so daß im Falle eines Lecks Umweltschäden weitgehend vermieden werden.Such tank walls with lining have the advantage of an improved Corrosion resistance and allow leak monitoring in the double-walled cladding, so that in the event of a leak environmental damage largely avoided.
Damit im Falle eines Lecks die doppelwandige Verkleidung der gegebenenfalls auftretenden Druckbelastung auf der Innen- oder Außenseite der Tankwandung standhalten kann, muß diese eine ausreichende Druck- und Scherfestigkeit besitzen. Andererseits darf die Scherfestigkeit der Verkleidung nicht zu hoch sein, um ein unvollständiges Anhaften und/oder Ablösen der Verkleidung von der Tankwandung zu vermeiden.So in the event of a leak, the double-walled cladding, if necessary occurring pressure load on the inside or outside of the Can withstand tank wall, this must have sufficient pressure and Have shear strength. On the other hand, the shear strength of the cladding not too high to be incomplete and / or adherent Avoid detaching the paneling from the tank wall.
Aufgabe der Erfindung ist es daher, einen Tank mit einer inneren und/oder äußeren doppelwandigen Verkleidung zu schaffen, der leckbeständiger ist und dabei einfach und schnell mit der Verkleidung ausrüstbar ist. The object of the invention is therefore to provide a tank with an inner and / or to create outer double-walled cladding, the more leak-resistant and can be easily and quickly equipped with the cladding.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
Hierdurch wird ein Tank mit einer inneren und/oder äußeren doppelwandigen Verkleidung geschaffen, dessen Verkleidung mit einer geringen Wandstärke den Anfordernissen an eine Leckschutzverkleidung genügt. So ist gegenüber bekannten doppelwandigen Verkleidungen aus einer Doppelpolware die Poldichte und Steghöhe wesentlich geringer, was eine geringere Scherfestigkeit zur Folge hat. Wird jedoch die erfindungsgemäße Einstellung in Verbindung mit den linienartig verlaufenden Stegwänden gewählt, erhält man eine optimale Verkleidung für Tankwandungen.This makes a tank with an inner and / or outer double-walled Cladding created, its cladding with a small wall thickness meets the requirements for leak protection cladding. So is compared to known double-walled cladding made of double-pole fabric the pole density and web height significantly lower, which is a lower Shear strength. However, the setting according to the invention selected in connection with the linear web walls, you get an optimal covering for tank walls.
Die eingesetzte Doppelpolware ist flach und damit kostengünstig herstellbar. Trotz der Flachheit wird ein Vollaufen des für die Lecküberwachung notwendigen Hohlraumes zwischen der Ober- und Unterware bei einer Tränkung mit einem härtbaren Harz vermieden. Das Harz bettet insoweit nur die Stege ein, so daß entlang der linienartigen Anordnung der nebeneinanderliegenden Polfäden weitgehend geschlossene Stegwände entstehen können. Diese verharzten Stegwände sorgen für eine ausreichende Scherfestigkeit der flachen Doppelpolware, wobei auch dann, wenn diese Stegwände überwiegend geschlossen sind, noch eine hinreichende Durchlässigkeit verbleibt, die für das Aufspüren von Lecks, insbesondere mit Druckluft, geeignet ist.The double pole fabric used is flat and therefore inexpensive to manufacture. Despite the flatness, the leak monitoring is full necessary cavity between the upper and lower goods avoid impregnation with a hardenable resin. The resin is so far only the webs, so that along the line-like arrangement of juxtaposed pile threads result in largely closed web walls can. These resinous web walls ensure sufficient Shear strength of the flat double pile fabric, even if this Bridge walls are mostly closed, still sufficient permeability remains for the detection of leaks, especially with Compressed air, is suitable.
Vorzugsweise sind die Ober- und Unterware eine Webware, in die die Polfäden unter Umschlingung von jeweils 5 bis 7 Schußfäden eingebunden sind. Je nach Wahl der Fadenstärke sind auf diese Weise die Abstände zwischen den Stegen bzw. Stegwänden und damit die Breite der Hohlraumkanäle einstellbar.The upper and lower fabrics are preferably a woven fabric into which the pile threads are inserted tied with 5 to 7 weft threads each are. Depending on the choice of thread size, the distances are in this way between the webs or web walls and thus the width of the cavity channels adjustable.
Als Fasermaterial für die Ober- und Unterware als auch die Polfäden sind hochfeste Fasern, insbesondere Glasfasern, bevorzugt.As fiber material for the upper and lower goods as well as the pile threads high-strength fibers, in particular glass fibers, preferred.
Das Anhaften der Doppelpolware auf der Tankwandung erfolgt vorzugsweise unter Vermittlung eines Harzes, das mit Glasfasern verstärkt sein kann und als Laminat die Doppelpolware beidseitig verstärken kann.The double pole fabric adheres preferably to the tank wall with the intermediation of a resin that can be reinforced with glass fibers and as a laminate can reinforce the double pile fabric on both sides.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further embodiments of the invention are the following description and the subclaims.
Die Erfindung wird nachstehend anhand des in den beigefügten Abbildungen dargestellten Ausführungsbeispiels der Erfindung näher erläutert.

Fig. 1 zeigt ein Teilstück einer Tankwand 1 eines im allgemeinen zylinderförmigen
Tanks zur Aufnahme von fließ- oder schüttfähigen Gütern, wie
insbesondere Chemikalien und petrochemischen Massengütern. An der Außen- oder
Innenseite der Tankwand 1 ist eine doppelwandige Verkleidung 2 befestigt.
Die Befestigung erfolgt vorzugsweise durch Anhaftung über ein
härtbares Harz, insbesondere ein duromeres Reaktionsharz, wie z. B. Polyesterharz.
Eine insbesondere aus Stahl bestehende Tankwand 1 kann
durch Aufrauhen, insbesondere durch Verwendung eines Sandstrahlverfahrens,
vorbehandelt werden. Eine aufgerauhte Tankwand 1 verbessert das
Anhaften der Verkleidung 2.Fig. 1 shows a section of a
Die doppelwandige Verkleidung 2 umfaßt eine durch ein härtbares Harz
versteifte Doppelpolware 3, die in einer oder mehreren nebeneinander gelegten
Bahnen die Tankwand 1 in Radial- oder Längsrichtung verlaufend
verkleidet. The double-
Die Doppelpolware 3 ist eine unaufgeschnittene Mehrlagenware mit einer
Oberware 4 und einer Unterware 5, die miteinander verbunden sind und zueinander
beabstandet gehalten werden durch Polfäden 6 (vgl. Fig. 2), die
zwischen der Oberware 4 und der Unterware 5 hin- und herwechseln und
dort Stege 7, 8 bilden. Durch Verharzen mit einem härtbaren Harz sind
die Oberware 4, die Unterware 5 und die Stege 7, 8 zu einem Bauteil versteift.The double-
Die Polfäden 6 sind dabei derart in die Oberware 4 und die Unterware 5
eingebunden, daß zwischen jeweils zwei benachbarten, von den Polfäden 6
beim Kreuzen zwischen Oberware 4 und Unterware 5 gebildeten Stegen 7 und
8, ein Längenabschnitt A von 5 bis 8 mm liegt. Handelt es sich bei der
Doppelpolware vorzugsweise um eine Webware mit verkreuzten Schußfäden 9
und Kettfäden (nicht dargestellt in Fig. 2), so kann dieser Längenabschnitt
A durch eine Einbindung der Polfäden 6 unter Umschlingung von
jeweils fünf bis sieben Schußfäden 9 in der Oberware 4 und Unterware 5
eingestellt werden. In Fig. 2 ist eine Umschlingung von jeweils fünf
Schußfäden 9 dargestellt. Vorzugsweise sind bei einer Webware als Doppelpolware
auch zwei Kettsysteme an Polfäden 6 vorgesehen, die abwechselnd
in die Oberware 4 und Unterware 5 einbinden. Die Dichte der unverharzten
Ober- und Unterware 4, 5 kann über die Zahl der Kettfäden und
Schußfäden 9 pro Quadratzentimeter eingestellt werden. Werden eine
lockere Ober- und Unterware 4, 5 gewünscht, um Lecks in der Tankwand 1
möglichst umgehend anzuzeigen, so können weniger Schußfäden als Heftfäden
pro Quadratzentimeter verteilt werden. Beispielsweise sind bei 10
Heftfäden pro Quadratzentimeter nur 9 oder 9,5 Schußfäden 9 verteilt.
Die Ober- und Unterware sind dann in einem gewissen Umfang undicht.The
Die Höhe der Stege 7, 8 beträgt nur 2,5 bis 3,5 mm. Die Polfäden 6 sind
ferner nebeneinander derart eingebunden, daß die gebildeten Stege 7, 8
linienartige und parallel zueinander verlaufende Stegwände 10 aus einer
Vielzahl einzelner Stege 7, 8 in Stegreihen bilden, die zusammen mit der
Oberware 4 und der Unterware 5 einzelne Hohlraumkanäle 11 begrenzen. Die
Höhe der Stege 7, 8 und damit der Stegwände 10 ist folgtlich kleiner als
die Breite der Stewandabstände. Die Stegwandabstände können mehr als
doppelt so groß sein wie die Höhe der Stegwände 10.The height of the
Die Stege 7, 8 entlang der Stegwände 10 sind vorzugsweise derart in das
erhärtete Harz eingebettet, daß die Stegwände 10 überwiegend verschlossen
sind. Die Oberware 4 und die Unterware 5 bilden somit zwei mit Abstand
zueinanderliegende und versteifte Wandungen, dessen zwischenliegender
Rauminhalt nur teilweise durch die ebenfalls versteiften Stegwände
10 gefüllt und sonst im wesentlichen leer ist.The
Als Fasermaterial für die Oberware 4, die Unterware 5 und die Polfäden 6
sowie deren Stege 7, 8 dienen hochfeste Fasern, wie z.B. Glasfasern,
Kohlenstoffasern und Aramidfasern. Die verwendeten Fasern können dabei
entweder als Stapelfasern zu Garnen versponnen oder als Mono- oder Multifilamente
ausgebildet sein.As fiber material for the
Die Verkleidung 2 kann schließlich mit einer Laminatlage 12, 13 aus vorzugsweise
glasfaserverstärktem Kunststoff ein- oder beidseitig verstärkt
und abgedeckt sein. Die obere Laminatlage 12 kann mittels einer Deckschicht
überzogen sein, wodurch eine besonders glatte Außenhaut erhalten
wird, die zudem eine Versiegelung bewirken kann. Die untere Laminatlage
13 kann eine Zwischenschicht zwischen Tankwand 1 und Verkleidung 2 bilden,
die einen zusätzlichen Aufbau der Tankwand 1 bewirkt und damit die
Lebensdauer eines Tanks erhöht.Finally, the
Zur Anbringung der Verkleidung 2 an der Tankwand 1 können eine oder
mehrere Bahnen der Doppelpolware in Radialrichtung des Tanks derart aufgelegt
werden, daß eine tankoberseitige Naht gebildet wird. Alternativ
kann ein Anlegen in Längsrichtung des Tanks erfolgen. Die Hohlraumkanäle
11 können dabei in einem Naht- oder Anschlußbereich enden und über diesen
miteinander kommunizieren, so daß auch bei einem weitgehenden Verschluß
der Stegwände 10 die verschiedenen Hohlraumkanäle miteinander
verbunden sind, wodurch die Lecküberwachung sich über die gesamte Verkleidung
erstrecken kann. Sind die Stegwände 10, insbesondere die Bereiche
zwischen den einzelnen Stegen in einer Stegreihe, durch die Harztränkung
nicht vollständig verschlossen, so können die Hohlkanäle 11
auch über die Stegwände 10 miteinander kommunizieren.To attach the
Zur Harztränkung der Doppelpolware dient ein härtendes Reaktionsharz, wie z.B. ungesättigter Polyester, Epoxide, Vinylester, Phenole, PUR, Silicone (SI), Polyimide (PI) oder Polyamidimide (PAI). Ebenso geeignet sind UV-härtende Harze.A hardening reactive resin is used to impregnate the double pile fabric, such as. unsaturated polyester, epoxies, vinyl esters, phenols, PUR, silicones (SI), polyimide (PI) or polyamideimide (PAI). Also suitable are UV-curing resins.
Eine Lecküberwachung erfolgt in der Verkleidung 2 mittels bekannter
Lecküberwachungssysteme.Leakage monitoring takes place in the
Das weitere Ausführungsbeispiel gemäß Fig. 3 unterscheidet sich von dem
vorstehend beschriebenen lediglich dadurch, daß die Verkleidung 2 unmittelbar
auf der Tankwand 1 haftet. Die Zwischenschicht 13 gemäß Fig. 1
entfällt. Im übrigen gelten die vorstehenden Ausführungsformen entsprechend.3 differs from that
described above only in that the
