Description
Sicherungseinrichtung an Flüssigkeitsbehältern Zusatz zu Patent 2 262 099 Die Erfindung betrifft eine Sicherungseinrichtung an Flüssigkeitsschältern, insbesondere an Grossraumbehältern für Kohlenwasserstoffe oder andere umweltgefährdende Flüssigkeiten zum Anzelgen einer Lockage und/oder Abwendung deren Folgen am Behälterboden und im Randbereich zwischen letzterem und der Behälterwand, wobei ein den Bodenquerschnitt in Bodennähe gasdicht abschliessender Trennboden vorgesehen ist, der zusammen mit dem Behälterboden einen vc, Behälterflüssigkeit freien, mit Gas gefüllten Raum bildet, und der in an sich bekannter Weise mess- und/oder regelbare Gasnu dem jeweiligen hydrostatischen Druck der Behälterflüssigkeit mindestens annähernd entspricht, und als Trennboden ein auf ierr. Behälterboden sich abstützender, tassenartig geformter Trenndienen kann boden dessen Wand durch eine mit der Behälterwand gasdicht verbundene schürze derart überdeckt ist, dass beim Füllen des Behälters eine gasdichte Trennung der beiden Räume (G und F) eintritt.Safety device on liquid containers Addendum to patent 2 262 099 The invention relates to a safety device on liquid containers, in particular on large-capacity containers for hydrocarbons or other environmentally hazardous liquids, to indicate a lock and / or avert its consequences on the container bottom and in the edge area between the latter and the container wall, one being the Bottom cross-section near the bottom gas-tight sealing separating bottom is provided which, together with the container bottom, forms a vc, container liquid-free, gas-filled space, and which in a known manner can be measured and / or regulated gasnu at least approximately corresponds to the respective hydrostatic pressure of the container liquid, and as a dividing floor on ierr. Container bottom of supporting, cup-like shaped separating bars can bottom the wall of which is covered by an apron that is connected to the container wall in a gas-tight manner in such a way that when the container is filled, the two spaces (G and F) are separated in a gas-tight manner.
Tritt eine Leckage an der Wandung auf, so wird eine solche Leckage mit don angegebenen Mitteln weder angezeigt noch verhindert. Dient der Behälter beispielsweise zur Aufnahme von kryogenen Flüssigkeiten, dann muss der gesamte Behälter von aussen mit einer Isoleerung versehen werden. Durch die aufgebrachte Isolierung kann der Austritt von Lagerflüssigkeit, die durch die eintretende Erwärmung in den Gas zustand übergeht, an der mit Isolierungsmaterial abgedeckten Wandfiäche nicht mehr festgestellt werden.If a leak occurs on the wall, such a leak is neither indicated nor prevented by the means indicated. Serves the Container for holding cryogenic liquids, for example, then the entire container must be provided with insulation from the outside. As a result of the insulation applied, the escape of storage liquid, which turns into a gas state as a result of the heating that occurs, can no longer be detected on the wall surface covered with insulation material.
Um diesen Nachteil zu vermeiden werden gemäss der Erfindung auf die Behälterhöhe verteilt Schürzen, beispielsweise bei zylindrischen Behältern waagrecht angeordnete zylindrische oder kegelförmige Ringkörper angebracht, die jeweils mit der Behälterwandung gasdicht verbunden sind, wobei in dem Zwischenraum zwischen den einzelnen Schürzen und der Behälterwand den Zwischenraum unterteilende Trennwände angeordnet werden, die mit der jeweils darunterliegenden Schürze ebenfalls gasdicht verbunden sind. Zur Versteifung der Schürzen können diese mit Sicken versehen werden.In order to avoid this disadvantage, according to the invention on the The container height distributes the aprons, for example horizontally in the case of cylindrical containers arranged cylindrical or conical ring body attached, each with the container wall are connected in a gas-tight manner, with in the space between the individual aprons and the container wall dividing the intermediate space dividing walls are arranged, which are also gas-tight with the apron underneath are connected. To stiffen the aprons, they can be provided with beads.
Dadurch wird erreicht, dass bei Zuführung von Fremdgas in den Zwischenraum zwischen der Behälterwandung und der Trennwand bzw.This ensures that when foreign gas is fed into the intermediate space between the container wall and the partition or
Schürze wie in dem Hauptpatent vorgesehen, keine Lagerflüssigkeit an die Wandfläche gelangen kann. Wird in dem Behälter eine kryogene Flüssigkeit gelagert, kann normalerweise eine Fremdgaszufuhr entfallen, da der nicht vermeidbare Zufluss von Wärme aus der Umgebung eine teilweise Verdampfung von Flüssigkeit bewirkt und sich die dabei entstehenden Gase in den entsprechenden Gasräumen sammeln. Der im Gasraum sich einstellende Druck entspricht dabei dem am unteren Schürzenende herrschenden jeweiligen hydrostatischen Druck.Apron as provided in the main patent, no storage liquid can get to the wall surface. Is a cryogenic liquid in the container stored, a foreign gas supply can normally be omitted, since the unavoidable The influx of heat from the environment causes partial evaporation of the liquid and the resulting gases collect in the corresponding gas spaces. Of the The pressure in the gas space corresponds to that at the lower end of the apron prevailing respective hydrostatic pressure.
Bei der Lagerung von kryogenen Flüssigkeiten werden normalerweise an der Wandung Versteifungsringe aussen angebracht, um Einbeulungen am Behältermantel bei der mit elner Ausserbetriebnahme verbundenen Wärmedehnung durch die Aussenisolierung zu vermeiden. Diese aussen angebrachten Versteifungsringe erhöhen den Wärmedurchgang beträchtlich, weswegen vorgeschlagen wird, zur Herabsetzung der Wärmeverluste diese Versteifungsringe an der inneren Wandfläche anzuordnen und diese als Träger der ein zelnen Schürzen und der Trennbieche zu benützen.When storing cryogenic liquids, usually Stiffening rings attached to the outside of the wall to avoid indentations on the container shell in the case of thermal expansion due to the external insulation associated with a shutdown to avoid. These externally attached stiffening rings increase the heat transfer considerable, which is why it is proposed to reduce the heat losses this To arrange stiffening rings on the inner wall surface and these as a carrier of the to use an individual apron and the dividing sheet.
Zur weiteren Herabsetzunz des schädizenden Wärmezuflusses werden bzwW. Schürzen die Räume zwischen den Trennwändenlund der ehälterwand mit Isolierungsmaterial gefüllt, um die Wärmeübertragung durch Konvektion zu vermindern.To further reduce the damaging heat inflow or. Cover the spaces between the partition walls and the container wall with insulation material filled to reduce heat transfer by convection.
Durch die vorgeschlagenen Massnahmen wird der Zutritt der eingelagerten Flüssigkeit an die Behälterwand durch die gebildete Gasschicht verhindert und damit die Isolierwirkung gegenüber der Umgebungsatmosphäre wesentlich verbessert. Durch die verringerte Verdampfungsrate der eingelagerten kryogenen Flüssigkeit werden erhebliche wirtschaftliche Vorteile durch die dann in geringerem Masse notwendige Rückverflüssigung erzielt.The proposed measures will prevent the stored Liquid to the container wall prevented by the gas layer formed and thus the insulating effect against the ambient atmosphere is significantly improved. By the reduced rate of evaporation of the stored cryogenic liquid considerable economic advantages through the then necessary to a lesser extent Reliquefaction achieved.
Die Uberwachung der Behälterwandung auf Dichtheit erfolgt in analogerweise wie im Hauptpatent dadurch, dass jeder Schürze zwei Messstellen zugeordnet werden, von denen die eine den im Raum zwischen der Behälterwand und der Schürze herrschenden Gasdruck und die andere den an dem unteren Ende der Schürze bestehenden hydrostatischen Druck auf ein Differenzmanometer beträgt.The monitoring of the container wall for leaks takes place in an analogous manner as in the main patent by assigning two measuring points to each apron, of which one prevails in the space between the container wall and the apron Gas pressure and the other is the hydrostatic pressure at the lower end of the skirt Pressure on a differential manometer.
Beim EiLS triv t einer Leckage wird diese im Differerzmarìometer durch die damit verbundene Druckänderung angezeigt und/oder durch die In dem Hauptpatent erwähnten Sigrlaleinrlchtullgen gemeldet.In the event of a leak, the differential marìometer shows it through the associated pressure change indicated and / or by the In the main patent mentioned Sigrlaleinrlchtullgen reported.
Dadurch, dass in die von den einzelnen Schürzen geDildeten Zwischenräume gesonderte, über den Umfang des 3ehälters verteilte Leitungen vorgesehen werden, durch die Fremdgas zuführbar ist, kann beim Eintritt einer Leckage der Austritt von Behälterflüssigkeit unterbunden werden, wenn der ursprüngliche Gasdruck wiederhergestellt und aufrechterhalten wird.The fact that in the spaces formed by the individual aprons separate lines distributed over the circumference of the container are provided, through which foreign gas can be supplied, the exit can occur if a leak occurs of container liquid are prevented when the original gas pressure is restored and is sustained.
ßird bei kryogenen Lagerflüssigkeiten durch die vorgesehenen oder zusätzlich angebrachten Leitungen ein tiefkaltes inertes Gas mit 6gegenüber der Behälterflüssigkeit niedrigerem Siedepunkt, z.B.In the case of cryogenic storage liquids, it is determined by the or additionally attached lines a cryogenic inert gas with 6 compared to the Lower boiling point container liquid, e.g.
flüssiger Stickstoff bei eingelagertem Flüssigmethan zugeführt, kann bei einem eventuellen Brand durch die eintretende Unterkühlung der Lagerflüssigkeit die Verdampfungsrate herabgesetzt und eine Brandbekämpfung erleichtert werden.liquid nitrogen supplied with stored liquid methane, can in the event of a fire due to the undercooling of the storage liquid the evaporation rate can be reduced and fire fighting can be made easier.
In der Zeichnung, die einen Teillängsschnitt eines erfindungsgemassen Behälters 1 darstellt, sind mit 2 die Behälterwand, mit 3 die an der Innenwand des Behälters angebrachten Versteifungsringe bezeichnet. An den Versteifungsringen 3 sind die Schürzen 4 und die Trennwände 5 gasdicht befestigt. Von jedem Versteifungsring 3 erstrecken sich nach oben die Trennwände 5 und nach unten die Schürzen 4, die zylindrisch oder mit nach unten kleineren Durchmesser ausgebildet sein können. Zwischen den Trennwänden 5 und der Behälterwand 2 ist Isoliermaterial 6 zur Verringerung der Wärmekonvektion eingelagert, das einen möglichst grossen Teil der Behälterinnenwand abdecken soll. erden keine Versteifungsringe benützt, so werden die abgewinkelten Schürzen 4 unmittelbar an der Behälterwand 2 gasdicht befestigt und können als Ersatz für Versteifungsringe dienen. Die Trennwände 5 werden in diesem Falle mit der Schürze 4 verbunden. Die unteren Enden der Schürzen 4 enden zweckmässig möglichst unmittelbar oberhalb der Versteifungsringe 3 bzw. bei Wegfall der Versteifungsringe 3 oberhalb der Anschlussstellen der Schürzen 4 an der Behälterwand 2. Damit wird erreicht, dass die über die Versteifungsringe 3 bzw. durch die Schürze 4 nicht vermeidbare von aussen eintretende Wärmezufuhr ein Verdampfen von Lagerflüssigkeit vorwiegend an den Stellen bewirkt, die von den jeweils darüber liegenden Schürzen abgedeckt sind. Damit wird bei kryogenen Lagerflüssigkeiten der für die Überwachung der Dichtheit des Behälters notwendige Gasdruck hergestellt und aufrechterhalten, so lange keine Leckage In dem Jeweiligen Schürzenbereich auftritt.In the drawing, which shows a partial longitudinal section of an inventive Container 1 represents, with 2 the container wall, with 3 on the inner wall of the Stiffening rings attached to the container. On the stiffening rings 3 the aprons 4 and the partition walls 5 are attached in a gas-tight manner. From every stiffening ring 3 extend upward the partition walls 5 and down the aprons 4, the can be cylindrical or with a smaller diameter downwards. Between the partition walls 5 and the container wall 2 is insulating material 6 for reduction the thermal convection stored, which is as large a part of the inner wall of the container as possible should cover. if no stiffening rings are used, the angled ones are used Aprons 4 attached directly to the container wall 2 in a gas-tight manner and can be used as a replacement serve for stiffening rings. The partition walls 5 are in this case with the apron 4 connected. The lower ends of the aprons 4 expediently end as directly as possible above the stiffening rings 3 or, if the stiffening rings 3 are omitted, above the connection points of the aprons 4 on the container wall 2. that the over the stiffening rings 3 or by the apron 4 cannot be avoided supply of heat entering from outside an evaporation of storage liquid mainly at the points caused by the respective overlying aprons are covered. In the case of cryogenic storage liquids, this becomes the one for monitoring the gas pressure required to ensure the tightness of the container is established and maintained, as long as there is no leakage in the relevant apron area.
Über die Leitungen 7 und 8 werden für jeden Schürzenbereich der Gasdruck und der zugehörige hydrostatische Druck zu den Differenzmanometern 9 übertragen. Die Leitungen 10 dienen zur Zuführung von Fremdgas in den Raum der einzelnen Schürzen.The gas pressure for each apron area is supplied via lines 7 and 8 and the associated hydrostatic pressure is transmitted to the differential manometers 9. The lines 10 are used to supply foreign gas into the space of the individual aprons.
