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 inner and / or outer double-walled lining according to the preamble of claim 1.

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 cladding have the advantage of improved corrosion resistance and allow leakage monitoring in the double-walled cladding, so that in the event of a leak environmental damage is 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.Thus, in the case of a leak, the double-walled lining can withstand the pressure load occurring on the inside or outside of the tank wall, it must have sufficient compressive and shear strength. On the other hand, the shear strength of the fairing must not be too high to avoid incomplete adherence and / or detachment of the fairing from the tank wall.

Aus der EP-A-0 504 708 ist ein faserverstärkter Kunststoffhohlkörper bekannt, der aus einer harzgetränkten Wicklung hochfester Fasern unter Verwendung eines härtenden Harzes besteht. Zur Ausbildung einer Tankwand mit einer schnell aufbaubaren Wandstärke ist vorgesehen, daß eine den Hohlkörperraum auskleidende, doppelwandige Haut aus einer unaufgeschnittenen Doppelpolware mit beabstandeter Ober- und Unterware sowie bindenden Polfäden in Form einer Wicklung eines oder mehrerer Gewebebänder eingewickelt und gehärtet ist. Hierdurch wird eine Tankwand mit einer inneren Sicherheitswand gebildet.From EP-A-0 504 708 a fiber-reinforced plastic hollow body is known, which consists of a resin-impregnated winding of high-strength fibers using a hardening resin. To form a tank wall with a rapidly build-up wall thickness is provided that the hollow body space lining, double skin from an uncut double pile fabric with spaced upper and lower fabric and binding pile threads wrapped and cured in the form of a winding of one or more fabric tapes. As a result, a tank wall is formed with an inner safety wall.

Aufgabe der Erfindung ist es daher, einen Tank mit einer inneren und/oder äußeren doppelwandigen Verkleidung zu schaffen, dessen Verkleidung eine verbesserte Stabilität besitzt.The object of the invention is therefore to provide a tank with an inner and / or outer double-walled panel, the panel has improved stability.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Hierdurch wird eine Tank mit einer inneren und/oder äußeren doppelwandigen Verkleidung geschaffen, dessen Verkleidung für eine ausreichende Scherfestigkeit einer flachen Doppelpolware sorgt, wobei noch eine hinreichende Durchlässigkeit verbleibt, die für das Aufspüren von Lecks, insbesondere mit Druckluft, geeignet ist. Die eingesetzte Doppelpolware ist flach und damit kostengünstig herstellbar.In this way, a tank is provided with an inner and / or outer double-walled panel whose cladding provides sufficient shear strength of a flat Doppelpolware, while still leaving a sufficient permeability, which is suitable for the detection of leaks, in particular with compressed air. The double-pile used is flat and therefore inexpensive to produce.

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.Preferably, the upper and lower fabric are a woven fabric, in which the pile threads are wrapped by wrapping each of 5 to 7 weft threads. Depending on the choice of thread thickness, the distances between the webs or web walls and thus the width of the cavity channels are adjustable in this way.

Als Fasermaterial für die Ober- und Unterware als auch die Polfäden sind hochfeste Fasern, insbesondere Glasfasern, bevorzugt.High-strength fibers, in particular glass fibers, are preferred as the fiber material for the upper and lower fabric as well as the pile threads.

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 adhesion of the double pile on the tank wall is preferably carried out by the intermediary of a resin which may be reinforced with glass fibers and as a laminate can reinforce the double pile on both sides.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further embodiments of the invention are described in the following description and the dependent claims.

Die Erfindung wird nachstehend anhand des in den beigefügten Abbildungen dargestellten Ausführungsbeispiels der Erfindung näher erläutert.

The invention will be explained in more detail below with reference to the embodiment of the invention shown in the accompanying drawings.

shows schematically a portion of a tank wall according to a first embodiment of the invention, wherein the head side, an upper laminate layer and a top fabric of a double pile are partially omitted,
Fig. 2

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 portion of a tank wall 1 of a generally cylindrical tank for receiving flowable or pourable goods, in particular chemicals and petrochemical bulk goods. On the outside or inside of the tank wall 1 a double-walled panel 2 is attached. The attachment is preferably carried out by adhesion via a curable resin, in particular a thermosetting reaction resin such. B. polyester resin. An existing particular steel tank wall 1 can be pretreated by roughening, in particular by using a sand blasting process. A roughened tank wall 1 improves the adhesion of the panel 2.

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-walled cladding 2 comprises a hardened by a resin hardened Doppelpolware 3, the tank wall 1 in one or more juxtaposed sheets clad in the radial or longitudinal direction.

Die Doppelpolware 3 ist eine unaufgeschnittene Mehrlagenware mit einer 0berware 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 pile fabric 3 is an uncut, multi-layer fabric with a top fabric 4 and a bottom fabric 5, which are connected to one another and held at a distance from each other by pile threads 6 (see Fig. 2), which change back and forth between the top fabric 4 and the bottom fabric 5 and there webs 7, 8 form. By hardening with a curable resin, the top fabric 4, the lower fabric 5 and the webs 7, 8 are stiffened into one component.

Die Polfäden 6 sind dabei derart in die 0berware 4 und die Unterware 5 eingebunden, daß zwischen jeweils zwei benachbarten, von den Polfäden 6 beim Kreuzen zwischen 0berware 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 pile threads 6 are incorporated into the upper 4 and the lower fabric 5 in such a way that between each two adjacent webs 7 and 8 formed by the pile threads 6 when crossing between upper 4 and lower fabric 5, there is a length A of 5 to 8 mm. If the double pile fabric is preferably a woven fabric with crossed weft threads 9 and warp threads (not shown in FIG. 2), this length section A can be formed by integrating the pile threads 6 while looping in each case five to seven weft threads 9 in the upper fabric 4 and Subware 5 can be set. In Fig. 2 a looping of five weft threads 9 is shown. Preferably, in a woven fabric as a double pile also two warp systems are provided on pile threads 6, which incorporate alternately in the upper fabric 4 and lower fabric 5. The density of the uncured upper and lower fabric 4, 5 can be adjusted by the number of warp threads and wefts 9 per square centimeter. If a loose upper and lower fabric 4, 5 desired to indicate leaks in the tank wall 1 as soon as possible, so less weft threads can be distributed as stitching threads per square centimeter. For example, with 10 stitching threads per square centimeter, only 9 or 9.5 weft threads 9 are distributed. The upper and lower fabric are then leaking to some extent.

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 folglich 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 webs 7, 8 is only 2.5 to 3.5 mm. The pile threads 6 are also adjacent to each other so integrated that the webs formed 7, 8 line-like and mutually parallel web walls 10 of a plurality of individual webs 7, 8 form in web rows, which together with the upper 4 and the lower fabric 5 individual cavity channels 11 limit. The height of the webs 7, 8 and thus the web walls 10 is therefore smaller than the width of the Stewand distances. The web wall spacings can be more than twice as large as the height of the web walls 10.

Die Stege 7, 8 entlang der Stegwände 10 sind 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 webs 7, 8 along the web walls 10 are embedded in the hardened resin such that the web walls 10 are largely closed. The upper fabric 4 and the lower fabric 5 thus form two spaced-apart and stiffened walls whose intermediate volume is only partially filled by the likewise stiffened web walls 10 and otherwise is substantially empty.

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 the fiber material for the upper fabric 4, the lower fabric 5 and the pile yarns 6 and their webs 7, 8 serve high-strength fibers, such. Glass fibers, carbon fibers and aramid fibers. The fibers used can either be spun as staple fibers into yarns or formed as monofilaments or multifilaments.

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.The cladding 2 may finally be reinforced or covered on both sides with a laminate layer 12. 13 of preferably glass-fiber reinforced plastic. The upper laminate layer 12 can be coated by means of a cover layer, whereby a particularly smooth outer skin is obtained, which can also cause a seal. The lower laminate layer 13 may form an intermediate layer between tank wall 1 and panel 2, which causes an additional structure of the tank wall 1 and thus increases the life of a tank.

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 panel 2 to the tank wall 1, one or more sheets of the double pile fabric may be laid in the radial direction of the tank such that a tank top seam is formed. Alternatively, it can be applied in the longitudinal direction of the tank. The cavity channels 11 may terminate in a seam or terminal area and communicate with each other over this, so that even with a substantial closure of the web walls 10, the various cavity channels are interconnected, whereby the leak monitoring can extend over the entire panel. Are the web walls 10, in particular the areas between the individual webs in a row of webs, not completely closed by the resin impregnation, the hollow channels 11 can also communicate with one another via the web walls 10.

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.The resin impregnation of the double pile is done by a hardening reaction resin, e.g. unsaturated polyesters, epoxies, vinyl esters, phenols, PUR, silicones (SI), polyimides (PI) or polyamide-imides (PAI). Also suitable are UV-curing resins.

Eine Lecküberwachung erfolgt in der Verkleidung 2 mittels bekannter Lecküberwachungssysteme.A leak monitoring takes place in the panel 2 by means of known leak monitoring systems.

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. The further embodiment according to FIG. 3 differs from the one described above only in that the cladding 2 adheres directly to the tank wall 1. The intermediate layer 13 according to FIG. 1 is omitted. For the rest, the above embodiments apply accordingly.
