Definitions

  • the invention relates to gas storage with at least two partial balloon-like flexible, inflatable, preferably tight membranes made of flexible material such as e.g. Plastic or rubber foils or plastic substrates coated with plastic or rubber, for example polyester fabrics coated with polyvinyl chloride, which are provided as an outer membrane and as an inner membrane, the inner membrane forming a pressure control chamber to which an auxiliary gas, preferably air, can be applied, the inner membrane a gas storage space concludes in or from which the gas to be stored is fed in and out with feed and discharge lines. is derivable, and wherein the edges of the membrane are fastened by means of clamping devices to a foundation through which the gas connection line opens into the gas storage space.
  • flexible material such as e.g. Plastic or rubber foils or plastic substrates coated with plastic or rubber, for example polyester fabrics coated with polyvinyl chloride, which are provided as an outer membrane and as an inner membrane, the inner membrane forming a pressure control chamber to which an auxiliary gas, preferably air, can be applied, the inner membrane a gas storage
  • Gas storage facilities with a relatively small capacity which are connected to gas producers and gas consumers and enable the collection, storage and delivery of gases in cases in which the generation and consumption of gas take place in different time sequences, have recently gained in connection with gas generation increased importance through biological processes.
  • an auxiliary gas most simply air, is blown into the pressure control chamber via a connection provided at this bottom until a predetermined desired pressure is obtained, the membrane transmitting this pressure to the gas in the gas storage space. Due to the overpressure in the pressure control space, the outer shell of the gas storage device can be kept dimensionally stable within wide limits, so that a wind pressure and / or a snow load remain without a significant influence on the gas pressure in the storage space. Both the balloon-like outer shell and the balloon-like membrane are too open at the bottom and the opening edges of these walls are fastened to a foundation plate by means of common clamping devices with the interposition of a seal.
  • an opening for the supply of the auxiliary gas, preferably air, to the pressure control chamber through the outer membrane is provided in a gas storage device of the type specified at the highest point and in the center of the outer membrane and that at least after the introduction of the auxiliary gas and the gas to be stored, the inner membrane has smaller outer dimensions in every direction than the outer membrane, and that the membrane with its lower (especially ring-shaped) edges are separated from each other at a horizontal distance, in particular by means of anchoring rings, tightly attached to the foundation.
  • connection point The position of the connection point and the new adjustment of the shape or dimensions of the membranes largely prevents the closure of the connection point to be feared according to the above.
  • the gas supply and gas discharge are thus fully guaranteed.
  • the heavy loads caused by frictional engagement between the membranes are also eliminated, so that there is additional freedom in the choice of materials.
  • the gas cell can then, for example, absorb the same stresses as the outer membrane, which can be a special safety factor.
  • the separate fastening of the lower membrane edges according to the invention has the further advantage that the inner membrane can be mounted on the foundation before the outer membrane is fastened, and therefore the fastening points of the inner membrane are easily accessible and good are verifiable.
  • the gas connection line opens approximately in the center of the interior of the inner membrane in the foundation, this interior and advantageously also the pressure control chamber using a floor membrane, e.g. made of plastic or rubber foils or textile substrates coated with plastic or rubber, for example polyester fabric coated with polyvinyl chloride, is sealed off from the foundation, in particular a reinforced concrete foundation disc. Due to the central inflow, a deformation of the inner membrane towards the side is largely prevented, which also counteracts a frictional engagement of the membranes. This happens in a special way if the inner membrane is approximately hollow cylindrical in the lower part and if this hollow cylinder merges into a hollow spherical cap at the top.
  • a floor membrane e.g. made of plastic or rubber foils or textile substrates coated with plastic or rubber, for example polyester fabric coated with polyvinyl chloride
  • a practically inexpensive construction of a gas storage device according to the invention advantageously takes place in such a way that the inner membrane, in particular made of meridian direction, welded to one another, advantageously fabric-reinforced plastic segments, and the outer membrane, which is also constructed in the same way, are detachable and tight on a metal anchored in the foundation. , appropriately steel plate are fastened by separate anchoring means.
  • straight clamping rails with a U-cross section with cap screws that can be screwed into the foundation anchor as well as flat bars and flat bars welded to the membrane plate for the outside diaphragm mounting on the metal plate are expediently provided for the inner membrane fastening, whereby the lower outer membrane edge between the flat bars and the flat bars is sealed by means of these screws is.
  • a measuring element is provided in the zenith of the gas accumulator for measuring or controlling the gas content of the inner membrane, which is attached to the foundation from the outer membrane, e.g. a steel cable that can be rolled up by means of a spring mechanism and has an explosion-protected angle-of-rotation former that defines the respective distance from the inner membrane as an electrical value to a control room.
  • the rotary angle former is attached to the shaft on which the steel cable is wound or rolled. The respective height of the inner membrane membrane and thus the memory content is passed on to the control room as an electrical value from the rotary angle former.
  • a safety valve with a liquid, in particular water, reservoir is arranged in the gas line, which is connected to the gas accumulator in an unblockable manner and serves to discharge excess gas quantities.
  • the outer membrane which is anchored separately on the foundation, is advantageous at least in its upper part, e.g. to make about a third of the total height heatable.
  • An electric heater can be provided for the practical implementation of such winter protection, e.g. in the form of an electr. Heating coil, electr. Heating foil or the like on, on or within or in the upper outer membrane part or between this part and an additional membrane provided in the upper part, which the heating coil, heating foil or the like. can also wear.
  • FIG. 1 and 2 show a side view and a top view of a gas container according to the invention, partly in section, partly in view, an embodiment with an inner membrane being indicated in FIG. 1 by dashed lines, the lower part of which is hollow cylindrical is executed.
  • the left part of FIG. 1 represents a section according to plane II of FIG. 2, the left part of FIG. 2 shows a top view after removal of the inner and outer membrane.
  • FIG. 3 shows a gas connection line that is switched on or on connected safety valve again.
  • 4 and 5 illustrate a measuring device for the memory content.
  • 6 to 9 show in partial top view (FIG. 6) and in sections (FIGS. 7 to 9) details of the fastening of the outer and inner membrane on the foundation. 7 is an enlarged section on the plane AA, FIG. 8 on the plane BB and FIG. 9 on the plane CC of FIG. 6.
  • FIG. 10 shows variants with devices for protection against excessive loads on the outer membrane, in particular against snow load.
  • a gas storage device 1 has at least two membranes or the like.
  • at least one flexible, partially balloon-like inflatable, tight inner membrane 3 or 3 ' is provided within a partially balloon-like flexible, inflatable, preferably tight, outer membrane 2 is.
  • These membranes consist of flexible material such as plastic or rubber foils or textile substrates coated with plastic or rubber, for example polyester fabrics coated with polyvinyl chloride.
  • the inner membrane 3 or 3 ' divides the interior of the outer membrane 2 into a between the outer membrane 2 and the inner membrane 3 or 3' lying, with an auxiliary gas, preferably air, pressurizable pressure control space 4 and at least one gas storage space 5 located within the inner membrane or from which the gas to be stored can be introduced or discharged with supply and discharge lines 6, 7.
  • the supply of the auxiliary gas, preferably the air, to the pressure control chamber 4 through the outer membrane 2 is provided approximately at the highest point and in the center of the outer membrane and at least after the introduction of the auxiliary gas and the gas to be stored, the inner membrane 3 or 3 'always has , etc. even with full gas filling, at least largely in smaller dimensions in every direction.
  • the inner membrane 3 or 3 'thus has in particular, a smaller outer surface on all sides or smaller outer dimensions in all directions in the same horizontal plane as the inner surface of the outer membrane 2.
  • the inner membrane 3 or 3 'and the outer membrane 2 at least as far as possible, have a distance from one another in every operating state.
  • the outer membrane 2 and the inner membrane 3 and 3 'according to the invention are separated with their lower, in particular annular, edge 8 and 9, in particular by anchoring rings 13 and 14, tightly attached to the foundation 12. This attachment takes place via a metallic, in particular steel base ring 15 which is attached to the foundation 12 by means of anchoring means 16, 17, 18 (FIGS. 6 to 9), for which purpose a counter ring 19 is also provided on the base ring 15 for the anchoring ring 13.
  • a considerable advantage of the configuration according to the invention is that when the air is introduced from above, both the air supply and the removal of the air is completely guaranteed and no closure can take place through the inner membrane 3 or 3 '. It is also achieved that the shape of the inner membrane remains stable.
  • the inner membrane 3 or 3 ' is so constructed that it is smaller than the outer membrane 2. It prevents contact between the inner membrane and the outer membrane, which has led to strong friction between the membranes in the prior art and which caused extraordinary loads .
  • the choice of material ensures that the gas cell can absorb the same stresses as the outer membrane, which is an additional safety factor. This is achieved by the special design of the reduction of the inner membrane with its bottom.
  • the gas connection line 6.7 opens approximately in the center of the interior 5 of the inner membrane 3 or 3 'in the foundation, this interior 5 and advantageously also the pressure control chamber 4 or 4' by means of a bottom membrane 20, e.g. of plastic or rubber foils or plastic substrates coated with plastic or rubber, for example polyester fabric coated with polyvinyl chloride, is sealed against the foundation 12, in particular a reinforced concrete foundation disc.
  • a bottom membrane 20 e.g. of plastic or rubber foils or plastic substrates coated with plastic or rubber, for example polyester fabric coated with polyvinyl chloride
  • straight clamping rails 14 with a U-cross section with head screws 17 which can be screwed into a foundation anchor 17 are provided for the inner membrane fastening, and flat rods 19 and flat iron 13 with head screws 13 'welded to the membrane curvature are welded to the metal plate 15 (FIG. 7), whereby by means of these screws, the lower outer membrane edge 8 can be tightly clamped between the flat bars and the flat bars.
  • the edge 9 of the inner membrane which is clamped between the parts 14 and 15, which, incidentally, can also be used for tight clamping or fastening or clamping the bottom membrane 20.
  • additional sealing strips or sealing inserts 23, 24 may also be present on or in the anchoring means.
  • a measuring element 25 is provided, for example, according to FIGS with an explosion-protected angle-of-rotation former, which forwards the respective distance to the inner membrane 3 or 3 'as an electrical value to a control room.
  • the explosion-protected rotary angle former is attached to the spring shaft, from which the respective height is passed on to the control room as an electrical value.
