Definitions

  • the invention relates to a container for the storage of frozen liquids, in particular liquefied gases, consisting of a reinforced concrete or prestressed concrete outer container closed on all sides and a steel inner container open at the top with the insertion of an insulating material, which serves to hold the liquid, the insulating material in the also open annular space between the two containers consists of a granulate on a mineral basis.
  • a steel inner container which is open at the top serves to hold the liquefied gas, the steel inner container being completely surrounded by a reinforced concrete outer container with the interposition of an insulating material.
  • the outer container must be earthquake-proof on the one hand, but on the other hand must also be able to withstand loads in the event of a gas cloud explosion.
  • the load case must also be dealt with such that it suddenly tears open. Since steel tends to become brittle at the low temperatures at which liquefied gas is stored, material defects in the steel can actually lead to an initially small crack widens into a continuous crack. The result of this is that the frozen liquid gas emerges from the crack and pours into the annular gap between the steel inner container and the reinforced concrete outer container and flows into the annular gap from the exit point in both directions.
  • the insulation consists of foam glass, which is able to withstand the static pressure of the steel inner tank and the liquid gas inside, the pearlite granulate is used for insulation in the annular space between the two tanks, which has the advantage of a high Insulation ability, non-flammable and relatively inexpensive.
  • the pearlite granules have a very low specific weight, which means that if the steel inner container is torn open, the insulation of the liquid which then emerges would not offer any appreciable resistance and would be displaced upward out of the annular gap by the liquid gas which escaped, so that the same consequences would then occur as if there was no insulating material between the two containers.
  • the invention has for its object to avoid inadmissible local pressure stresses of the reinforced concrete outer container for a container of the type mentioned in the event of a crack in the steel inner container.
  • At least one annular locking body is arranged between the reinforced concrete outer container and the steel inner container, which is attached to the reinforced concrete outer container or the steel inner container and leaves a space between the two containers.
  • the measure according to the invention it is achieved that in the case of a sudden tearing of the steel inner container, the emerging liquid cannot suddenly displace the light granules, so that the flow velocity of the emerging liquid is greatly reduced and the two partial flows on the side opposite the exit point are no longer gushing can meet.
  • the blocking body does not establish a connection between the two containers, the formation of a cold bridge is prevented and an unhindered pressure equalization is permitted.
  • a locking body is preferably arranged parallel to the floor at the level of the upper edge of the steel inner container, but further locking bodies can also be provided in levels below the upper edge of the steel inner container.
  • a locking body can also be attached to the roof dome of the reinforced concrete outer container, which extends approximately parallel to the axis of the container in the direction of the upper end of the steel inner container.
  • Fig. 1 shows a reinforced concrete outer container, which consists of a base plate 1, a wall 2 and a roof dome 3.
  • the wall thickness of the steel inner container 5 is approximately 14-30 mm
  • the thickness of the insulation 4 is approximately 1 m
  • the wall thickness of the reinforced concrete outer container is approximately 50 cm.
  • the insulation under the bottom of the steel container consists of foam glass, which is able to withstand the static load on the container 5 filled with liquid gas endure, while the insulation on the ceiling is made of mineral wool.
  • the annular gap between the two containers is filled with a granulate of pearlite.
  • the non-combustible pearlite granulate has the advantage that it can be introduced into the annular gap in a simple manner, but that it can also be removed just as easily by suction for inspection purposes or for necessary repair work.
  • annular locking body 6 is provided at least in the vicinity of the upper end of the steel inner container 5, FIG. 2 showing a possible embodiment and fastening form for such a locking body.
  • the locking body 6 is designed as an annular disk which is fastened to the wall 2 of the reinforced concrete outer container with the aid of cross members 9.
  • the attachment can be done by means of screws 10 and bolts 11 anchored in reinforced concrete.
  • the radial dimensions of the disc 6 are smaller than the distance between the outside of the sheet metal cladding 12 and the outside of the mineral fiber mat 13, so that an intermediate space 14 remains through which pressure equalization can take place. If necessary, holes or slots 15 can also be provided in the annular disk 6 will.
  • the liquid gas then escaping would be strongly prevented from flowing rapidly in the space between the containers, since the blocking body 6 ensures that the pearlite granules only to a limited extent through the space 14 and possibly the holes or Slots 15 can emerge, so that the space between the containers only slowly seeps away and a gushing collision of partial liquid flows is prevented.
  • the liquid gas penetrates into the interspace evaporation gases can also escape through the interspace 14 and, if appropriate, the holes or slots 15.
  • Model tests have shown that the covered surface of the space between the containers should be approximately 50% to 90% of the total surface.
  • Fig. 1 it is indicated that optionally further locking bodies 7 and 8 can be provided in levels below the upper edge of the container, which are of the same design as the steel body shown in Fig. 2.
  • the locking body 6 it is possible to fasten the locking body 6 to the roof dome 3, the locking body extending approximately parallel to the container axis and extending to the upper end of the steel inner container 5.
  • the space for the limited passage of the pearlite granules in the event of bursting is here formed by one or more openings 15 in the blocking body 6 above the insulation above the steel inner container 5.
  • the end of the locking body 6 overlaps the upper end of the steel inner container 5-
  • the locking body could also be attached to the upper end of the steel inner container 5 and then form a distance from the roof dome 3.
