Abstract

The invention relates to a rotating device which is externally operated and which is used for all upper extraction lines which are located in the latent heat accumulators, in addition to an internal melting line. The invention is characterised in that the upper extraction lines (1), which are arranged in the latent heat accumulator, are connected to a toothed rack (3) which is fixed in a joint. Said toothed rack can be externally displaced by means of a lever enabling the extraction lines (1) to be rotated about 180°. The opening bores (2) can be rotated in a downward direction during transportation due to said rotation thus preventing the PCM (phase changing material), which is in the tank, from entering into or remaining in the suction line and then guiding it into the heat exchanger. The invention is also characterised in that a branch (6), which is used as a melting line, is arranged on the supply lines (5) counter to the direction of flow. Said melting line is initially connected directly to the extraction line (4) by the PCM in a downward direction and then in an upward direction. It is also possible to carry out a melting process, in the event of completely crystallised PCM, without requiring an external melting device.

Description

Verdreheinheit zur einheitliche Verdrehung von Sauqleitungen einer La- tentwärmespeichereinheit, sowie eine auf Basis des Fliesverhaltens automatisch funktionierende AufschmelzeinrichtungTwisting unit for the uniform rotation of sowing lines of a latent heat storage unit, and a melting device which automatically functions on the basis of the flow behavior

1. Verdreheinheit1. twisting unit

Aus PCT/DE99/03861 ist der Latentwärmespeicher in seiner Funktion bekannt. Aus PCT/EP01 /09801 ist eine Förderabsperrung bekannt.From PCT / DE99 / 03861 the latent heat storage is known in its function. PCT / EP01 / 09801 a Förderabsperrung is known.

Die Funktionalität eines Latentwärtmespeichers, basierend auf PCT/DE99/03861 hängt, hängt insbesondere beim Transport davon ab, dass vermieden werden muss, dass das in dem Container befindliche Phase Changing Material - PCM - in das Entnahmeleitungssystem gelangt, denn in diesem Falle wird der externe Wärmetauscher mit dem PCM verstopft, das System bleibt stehen.The functionality of a Latentwärtmespeichers, based on PCT / DE99 / 03861 depends, depends in particular during transport on the fact that it must be avoided that the container located in the phase Changing Material - PCM - enters the sampling line system, because in this case the external Heat exchanger clogged with the PCM, the system stops.

Die in PCT/E P01/09801 beschriebene Förderabsperrung weißt im normalen Betrieb große Mängel auf:The delivery shut-off described in PCT / E P01 / 09801 has major shortcomings in normal operation:

Bei der praktischen Anwendung dieser Förderabsperrung hat es sich nachteilig ausgewirkt, dass Salzkristalle in den Zwischenraum des Rohr- in Rohrsystems gelangten und dann das Förder- Absperrorgan bis zur Unbrauchbarkeit beschädigten.In the practical application of this Förderabsperrung it has had an adverse effect that salt crystals in the space of the pipe in tube system arrived and then damaged the delivery obturator to uselessness.

Um dem Latentwärmespeicher die notwendige Leistung bis zu 1 MW zu geben, müssen im oberen Bereich des Latentwärmespeichers mehrere Saugleitungen installiert werden.To give the latent heat storage the necessary power up to 1 MW, several suction lines must be installed in the upper area of the latent heat storage.

Die Erfindung betrifft eine Technik, welche verhindert, dass PCM in d Entnahmelei- tungsssystem, bestehend aus mehreren Rohren, eindringt und dort verbleibt. Hierzu wird, wie in Zeichnung 1 dargestellt, eine extern zu bedienende Verdreheinheit gebaut.The invention relates to a technique which prevents PCM from entering and remaining in the withdrawal line system consisting of several pipes. For this purpose, as shown in drawing 1, an externally operated Verdreheinheit built.

Die Konstruktion ist dermaßen gestaltet, dass, gemäß Zeichnung 2, bei einem oder mehreren der Saugrohre eine Verbindung zur Außenseite hergestellt wird, an welcher dann jeweils ein Hebel zum Ausüben der Verdreh beweg ung befestigt ist.The construction is designed so that, according to drawing 2, at one or more of the suction pipes, a connection to the outside is made, to which then each a lever for exerting the twist is moved beweg attached.

Zum einen kann, falls nur eine Entnahmeleitung installiert ist, dieses über den Hebel gemäß Zeichnung 1 ,von außen in die gewünschte Position gedreht werden, zum anderen kann dann über ein Zahnstangen- und Zahnradsystem (3), gemäß Zeichnung 1 die Drehbewegung auf die anderen Entnahmeleitungen (1) übertragen werden. Alle an das Verdrehsystem angeschlossenen Rohre werden somit gleichzeitig in die gewünschte Position gedreht.On the one hand, if only one sampling line is installed, this can be rotated via the lever according to drawing 1, from the outside to the desired position, on the other hand then via a rack and pinion system (3), according to drawing 1, the rotational movement to the other Extraction lines (1) are transmitted. All pipes connected to the twisting system are thus simultaneously turned to the desired position.

Durch Einrastpositionen können die Entnahmeleitungen so gedreht werden, dass für den Transport des Latentwärmespeichers die Öffnungen nach unten und für den Betrieb nach oben gedreht werden können. 2. AufschmelzeinrichtungBy latching the extraction lines can be rotated so that for the transport of the latent heat storage, the openings can be turned down and up for operation. 2. Melting device

Wird ein Latentwärmespeicher für längere Zeit nicht benutzt, das heißt wird das PCM nicht geschmolzen, so kristallisiert das PCM zu einem Monokristall aus.If a latent heat storage for a long time not used, that is, the PCM is not melted, the PCM crystallized into a monocrystal.

Da in der Regel an der Ladestelle eines Latentwärmespeichers keine Möglichkeit gegeben ist das System mittels einer zusätzlichen, externen Wärmequelle, z.B. Dampf wieder aufzuschmelzen, muss der „eingefrorene" Latentwärmespeicher an eine Ort gebracht werden, wo der Aufschmelzvorgang ausgeführt werden kann.Since there is usually no possibility at the loading location of a latent heat store, the system can be replaced by an additional, external heat source, e.g. To re-melt steam, the "frozen" latent heat storage must be brought to a location where the reflow process can be performed.

Aufgabe der Erfindung ist es, eine Vorrichtung zu konstruieren, dass der Aufschmelzvorgang automatisch an der Wärmequelle, mit dem heißen Wärmeträgeröl erfolgen kann.The object of the invention is to construct a device that the melting process can be done automatically at the heat source, with the hot heat transfer oil.

Gelöst wird diese Aufgabe durch eine Konstruktion gemäß Zeichnung 2.This problem is solved by a construction according to drawing 2.

In das Einleitesystem (5), wird ein Abzweig (6) eingebracht. Dieser Abzweig weißt das Merkmal auf, dass es mindestens 120° entgegen der Fließrichtung eingebracht wird.In the introduction system (5), a branch (6) is introduced. This branch has the characteristic that it is introduced at least 120 ° counter to the direction of flow.

Dieser Abzweig stellt den Anfang der eigentlichen Aufschmelzleitung gemäß Zeichnung 2 dar. Die Aufschmelzleitung (6) ist so gestaltet, dass diese von oben kommend, um alle unteren Zuführrohre und dann wieder nach oben, zur Entnahmeleitung (4) geführt werden. Damit ist eine optimale Aufschmelzung des PCM, die problemlose Inbetriebnahme des Systems gewährleistet.This branch represents the beginning of the actual Aufschmelzleitung according to drawing 2. The Aufschmelzleitung (6) is designed so that they come from above, all lower feed tubes and then back up to the sampling line (4). This ensures an optimal melting of the PCM, the trouble-free commissioning of the system.

Ist das PCM auskristallisiert, kann das Wärmeträgeröl nicht durch das Leitungs- und Containersystem gepumpt werden, es baut sich im Einleitesystem ein Druck auf. Dieser Druck bewirkt, dass heißes Wärmeträgeröl in den Abzweig (6) und somit in die Aufschmelzeinheit (6), welche ein offener Kreislauf gemäß Zeichnung 2 darstellt, gelangt.Once the PCM has crystallized out, the thermal oil can not be pumped through the piping and container system, pressure builds up in the inlet system. This pressure causes hot heat transfer oil in the branch (6) and thus in the Aufschmelzeinheit (6), which represents an open circuit according to drawing 2 passes.

Es wird ein Kreislauf in Gang gesetzt, welcher bewirkt, dass durch die Aufschmelzeinheit (6) heißes Öl fliest. In der nahen Umgebung der Aufschmelzeinheit (6) schmilzt das PCM, ein Durchflusskanal für den eigentlichen, großen Ölfluss wird geöffnet.A circuit is initiated which causes hot oil to flow through the reflow unit (6). In the vicinity of the melting unit (6), the PCM melts, a flow channel for the actual, large oil flow is opened.

Ist dieser Aufschmelzkanal groß genug, dass das im Einleitesystem (5) befindliche Öl mit dem aufgebauten Druck durch diesen fließen kann, wird der große Ölkreislauf automatisch in Gang gesetzt. Gleichzeitig wird wegen des abfallenden Drucks der Aufschmelzkreislauf automatisch geschlossen und stillgelegt. If this melting channel is large enough that the oil in the inlet system (5) can flow through it with the built-up pressure, the large oil circuit is automatically started. At the same time, the reflow cycle is automatically closed and shut down because of the falling pressure.
