Description

Verfahren und Einrichtung zur Verhinderung von Leckverlusten an Flüssigkeits-Lagerbehältern mit Unterdruck im Luftraum des Behälters Die Erfindung bezieht sich auf ein Verfahren und eine Einrichtung zur Verhinderung von Leckverlusten an Flüssigkeits-Lagerbehältern. . Hierbei wird im Luftraum des Behälters mittels einer Vakuumpumpe ein Unterdruck erzeugt und bei etwaigen Druckänderungen wiederhergestellt, der mindestens so groß ist wie die hydrostatische Höhe der Flüssigkeit an der tiefsten Stelle des Behälters; außerdem ist im Behälter ein Flüssigkeitsniveaumeßgerät zur füllhöheabhängigen Steuerung des Unterdruckes vorgesehen.Method and device for preventing leakage losses on liquid storage containers with negative pressure in the air space of the container The invention relates to a method and means for preventing leakage from liquid storage containers. . A vacuum pump creates a negative pressure in the air space of the container generated and restored in the event of any pressure changes that is at least as great is like the hydrostatic height of the liquid at the deepest point of the container; In addition, there is a liquid level measuring device in the container for level-dependent control of the negative pressure provided.

Wird bei einem durch dieses Verfahren geschützten Behälter infolge überhöhten Vakuums im Luftraum des Behälters Grundwasser durch ein Leck im Lagerbehälter hochgesogen, so besteht die Gefahr einer Überfüllung des Behälters und des Eindringens von Lagerflüssigkeit oder Grundwasser in das Evakuierungssystem. Will result in a container protected by this process Excessive vacuum in the air space of the groundwater container due to a leak in the storage container sucked up, there is a risk of overfilling the container and penetration of storage liquid or groundwater into the evacuation system.

Diese Gefahr wird erfindungsgemäß dadurch vermieden, daß das Flüssigkeitsniveaumeßgerät zur Überfüllsicherung bei Flüssigkeitseinbruch durch eine Leckstelle die Vakuumpumpe abschaltet, wenn der Flüssigkeitsstand im Behälter einen vorbestimmten Höchstwert überschreitet. According to the invention, this risk is avoided in that the liquid level measuring device the vacuum pump to prevent overfill in the event of liquid ingress through a leak switches off when the liquid level in the container reaches a predetermined maximum value exceeds.

Als Flüssigkeitsniveaumeßgerät kann hierbei ein bekanntes Gerät dieser Gattung verwendet werden. A known device can be used as the liquid level measuring device Genus are used.

Handelt es sich um einen Behälter für elektrisch nichtleitende Flüssigkeiten, so können nach einem weiteren Vorschlag der Erfindung als Flüssigkeitsniveaumeßgerät im Behälter in einer vorbestimmten Füllhöhe an sich bekannte Spürsonden für elektrisch leitende Flüssigkeiten angeordnet sein. Diese gelangen bei Anwesenheit von Grundwasser im Behälter zur Wirkung.If it is a container for electrically non-conductive liquids, so can according to a further proposal of the invention as a liquid level measuring device in the container at a predetermined level known per se sensing probes for electrical conductive liquids be arranged. These get there in the presence of groundwater in the container to the effect.

Eine Abwandlung des Erfindungsgedankens besteht bei dem eingangs definierten Verfahren darin, daß das Niveaumeßgerät zur Auslösung eines Alarmsignals dient, wenn der Flüssigkeitsstand im Behälter ansteigt, ohne daß der Lagerbehälter auf normalem Wege, z. B. über den Füllstutzen, befüllt wird. There is a modification of the concept of the invention at the beginning defined method in that the level measuring device to trigger an alarm signal is used when the liquid level in the container rises without the storage container in the normal way, e.g. B. is filled via the filler neck.
