Definitions

  • the invention relates to a double-walled container for cryogenic liquids, primarily for liquefied petroleum gas, with an inner tank as the primary storage container and an outer tank made of prestressed concrete as a secondary safety container, a thermal insulation layer arranged between the two containers and a joint construction between the wall and the base plate of the safety container, in which the joint area is continuous is bridged by a steel joint plate clamped at its ends.
  • Containers for frozen liquids are usually made of two shells for safety reasons, whereby the inner container, which is used for the actual storage, is made of steel, while a second tank made of steel or concrete encloses the inner one as a safety container and, if the inner container leaks, the leakage must catch. Cold insulation is arranged between the two containers. In order to be able to fulfill its function, the outer container must also withstand a catastrophe load without destruction.
  • Such containers are approved in special approval procedures and are to be dimensioned due to the high security risk for unusual and building-specific load cases.
  • These load cases include explosion pressure waves and earthquakes as planned load cases and temperature shock as catastrophic events, which, however, should not be taken into account at the same time.
  • concrete containers have advantages over steel containers.
  • the material already gives you greater security against deliberate or unintentional damage from outside or against accidents.
  • the outer concrete containers have so far been designed without joints, since the construction problems of a joint for containers of this type could not be satisfactorily solved.
  • DE-OS 2016441 describes a structural connection, primarily for a reactor vessel, with a joint-like space between the wall and the base plate, which in the final state is kept free of concrete and only pierced by at least two concentric surfaces of layers of vertical reinforcing bars. The space left open allows for lateral shifts. Such a joint formation is cumbersome and complex and also transmits moments in the attachment area between the wall and the base plate, where they are to be avoided according to the invention.
  • the object of the invention is to develop a double-walled liquid tank with a concrete container as an outer shell, which avoids the disadvantages of the known construction and survives foreseeable catastrophes with greater certainty without destruction.
  • the solutions according to the invention separate the wall from the sole in the container in the critical transition area. This creates manageable and predictable parts in their static effect, which are assigned clear functions through appropriate design and which can be economically measured. Force-transmitting connecting elements are attached between the wall and the sole.
  • the two alternative solutions differ in how possible from hori vertical forces resulting from zontal pressure waves.
  • the solution according to claim 1 assigns the absorption of the vertical forces to the joint plate (9), which has to be made thicker for this task and thus becomes stiffer and therefore, in the case of temperature shock by preventing its shrinkage due to sudden cooling, stronger forces on the mounting structures (10, 11) and exercises the concrete. These forces are to be absorbed by flexible, plastically deformable design of the anchoring constructions with angular, bent steel elements (12).
  • the tensile forces are assigned special anchors (27) penetrating the joint. This solution is recommended if the size of the vertical tensile forces would lead to uneconomical dimensions of the joint plate and its anchoring.
  • the joint plate (38) is relieved by the anchors (27) and can be made thinner. In the event of a catastrophic temperature shock, such a sheet can plastically deform without exerting excessive stress on the mounting structures (49, 50).
  • Measures according to claims 3 to 6 serve to absorb the horizontal force from a pressure wave. So that the base plate can act as an abutment for the container part above the sliding joint, sudden pressure surges must be able to be non-positively introduced into the base plate from the rising structure, at the same time - despite that non-positive horizontal storage - slow horizontal displacements of the rising structure on the base plate may be possible.
  • This task is solved by filling the joint with viscoelastic casting compound.
  • the two-stage design of the joint with a narrower lower and a wider upper space creates a buffer space at the top into which potting compound is displaced when the gap is narrowed, or from which potting compound can flow when the gap is widened. Since these movements are very slow with the required viscosity of the potting compound, heating cables can be provided through which the mass is specifically heated and the flow movements are accelerated.
  • Claim 5 describes an alternative solution for generating the non-positive connection in the joint.
  • the joint is closed pressure-tight and tight on all sides and the space is filled with a liquid which is connected to a pressure vessel via at least one line.
  • the flow rate in the connecting line can be controlled with a control valve.
  • Non-positive connection in the joint is achieved in that, in the event of a sudden impact, the liquid practically cannot escape from the joint space, while, depending on the setting of the control valve, the liquid exchange can take place more or less quickly if the joint volume changes slowly.
  • the heating pipe 39 serves to keep the wall temperature of the outer container constant in the binding area of the sheet metal of the partition, which acts as a cold bridge, in order to avoid singular temperature stresses in this wall area.
  • the double-shell cylindrical tank system 1 is built up from the inner tank 2 and the outer tank 3 surrounding it as a protective container.
  • the space 4 between the two containers is filled with differently constructed insulating material.
  • the joint 5 separates the wall 6 from the base plate 7.
  • the joint 5 is on the inside bridged by the steel joint construction 8.
  • the embodiment of a joint construction according to claim 1 consists of the joint plate 9 and the binding rings 10, 11, which are made of Z-profiles 12 with anchor iron 13 and clamp the joint plate in the wall 6 or the base plate 7 of the outer tank 3.
  • the space behind the joint plate 9 is filled with plastically deformable material 14.
  • the profiles 12 can deform in the event of a disaster.
  • the partitioning 16 spans between the base plate 15 of the inner tank 2 and the joint construction 8. It has on its outer edge an upturned collar 17 which is welded on at an angle upwards and with which it is fastened tightly to the joint plate 9.
  • the base plate 7 of the outer tank 3 is provided with an upstand 18 which concentrically surrounds the wall 6.
  • Fig. 3 shows the upper tie ring 10 of a joint construction 8 in the wall 6 of the outer tank 3 and dashed its position after a catastrophe due to cold shock, which results in a sudden severe shrinkage of the upper part of the joint construction in contact with the cryogenic liquid.
  • Z-profiles 12 by virtue of their webs 19 acting as lever arms, can be deformed by the formation of flow joints 20 and can undergo the shrinking movement without the concrete of the wall 6 breaking.
  • the mode of operation of the partition 16 with the upturned collar 17 can also be seen.
  • the liner 21 made of thin cold-tough steel is anchored in the concrete by welding dowels 22, is welded to the joint plate 9 with its lower edge 23 and can follow the movement of the joint plate. At its upper edge 24 it is tightly connected to the sealing skin 25.
  • the liner 21 prevents the sealing skin of the outer container from tearing off in the joint area.
  • the joint plate 38 has only a small thickness. It can therefore easily deform and only emits small forces on the mounting constructions 49, 50. In order not to hinder its deformation, it is backed with plastically deformable material 51.
  • the cladding tubes 28 are closed at their upper and lower ends by sleeves 29.
  • the space 30 between the armature 27 and the cladding tube 28 can be pressed with an anti-corrosion agent through a pressing line 31.
  • the upstand 18 serves as an abutment against lateral displacements of the wall 6.
  • a joint 32/33 opens with a lower area 32 with a smaller and an upper area 33 with a greater width, which is filled with viscoelastic casting compound.
  • the sealing compound is drawn through in the upper joint area by a heating line 34.
  • a tight partition 35 is arranged in the insulation space 4. It has annular compensators 36.
  • Recesses 41 are provided in the relatively stable insulating material 40 of the bottom area between the inner and outer tanks, in which the compensators can move.
  • FIGS. 5 and 6 show alternative non-positive joint fillings.
  • the joint 42 is pressure-resistant and expandable on all sides and is enclosed by thin-walled sheet metal elements 43.
  • the closed joint space 44 and the pressure vessel 45 which are connected to one another via a line 46 and the control valve 47, are filled with liquid.
  • the liquid does not fill the joint space 44 directly, but indirectly in an elastically stretchable, tight tube 48.
