Definitions

  • the invention relates to a storage container for flammable liquids, such as gasoline, heating oil or the like, with a gas- and liquid-tight lining which covers at least the floor and the walls and has an outer jacket and an inner jacket made of layered polyester laminates and a profiled surface element. keeps the outer jacket and inner jacket at a distance from each other and connects them, whereby a gas and liquid-tight interstitial space is formed between the outer jacket and the inner jacket.
  • flammable liquids such as gasoline, heating oil or the like
  • a storage container of this type is known (DE-GM 19 74 383), in which the gas and liquid-tight monitoring space is connected to a probe with which the type of liquid which has penetrated into the monitoring space can be determined and from this conclusions about leaks in the inner jacket or outer jacket of the lining can be pulled. Since the plastics used for the lining have a high resistance to aggressive liquids, but are poorly electrically conductive, there is a risk of sparking when filling and completely or partially emptying the container with flammable liquids, which could ignite the contents of the container and explode Can lead container.
  • the object of the invention is to avoid these disadvantages and to design the lining for a storage container for flammable, preferably highly explosive liquids so that the tightness of the lining can be monitored with it and, with high strength of the lining, reliable explosion protection is ensured.
  • a carbon fiber fleece is embedded in the surface of the inner jacket of the lining facing the container interior, which is electrically connected to the earth potential.
  • the inner jacket is stiffened in all directions to withstand pressure, tension and bending.
  • the carbon fiber fleece which can be placed directly on the surface of the inner jacket, ensures reliable electrostatic discharge.
  • the storage container can be used for practically all flammable and highly flammable liquids.
  • the carbon fiber fleece point by point into the surface of the inner shell in such a way that the polyester resin of the inner shell partially reaches the surface of the carbon fiber fleece and anchors it to the inner shell.
  • This anchoring can be carried out, for example, in such a way that the carbon fiber fleece is pressed into the inner surface of the inner shell, which is made of polyester resin, with a spiked roller. The carbon fiber fleece is then still on the surface of the inner jacket, but is firmly connected to it and cannot detach from the inner jacket.
  • the surface of the carbon fiber fleece can be sealed with a non-tacky, unsaturated polyester resin layer.
  • a pure resin is expediently used for this sealing so that the container can be easily illuminated and inspected during inspection visits. Due to the smooth surface, the interior of the storage container can be easily cleaned and less contaminants settle on the inner wall of the container.
  • the profiled surface element expediently ends above the highest liquid level in the container.
  • the entire outer surface and the inner surface can then be connected to one another and then attached to the container in the corner of the container wall and the container ceiling.
  • This can be done by gluing the lining in the upper corner of the container wall and container ceiling; however, it is also possible to provide a circumferential groove in the upper corner of the container wall and container ceiling, into which the upper edge of the lining is drawn and anchored with a synthetic resin cement.
  • the groove with the container wall expediently forms a sharp edge, which is around this edge drawn lining holds securely, which is appropriately pressed into the groove so that it lies close to the groove walls.
  • the synthetic resin putty then fills the groove.
  • arresters formed as metal strips at a distance from one another under the carbon fiber fleece, which have surface contact with the fleece and are connected to at least one busbar connected to the earth potential. This ensures that the lining can not charge more strongly in some areas, but an electrostatic charge is immediately distributed over the entire container and is discharged simultaneously in several places.
  • the busbars are preferably metal strips which are attached to the container wall all the way around at a short distance from the container ceiling and / or from the container bottom. In this way, they connect all the arresters to one another, which are glued to the inner jacket of the lining at a lateral spacing, preferably in a vertical position under the fleece.
  • the arresters can be led up to the tank ceiling and glued there.
  • at least one busbar is expediently connected to a metal socket which is arranged in an opening in the container ceiling and is connected to the earth potential.
  • a metal socket which is arranged in an opening in the container ceiling and is connected to the earth potential.
  • This can be, for example, the dome of the container or a metal ring surrounding the entry or inspection opening, which in turn is connected in a suitable manner to the earth potential.
  • 10 denotes a storage container for diesel oil or kerosene, the bottom 11, ceiling 12, peripheral wall 13 and inner supports 14 of which are made of reinforced concrete and connected to one another to form a monolithic body.
  • the storage container 10 can be an above-ground container, but can also be embedded in the ground. It is also conceivable to manufacture it from sheet steel, synthetic resin concrete or another high-strength material. In any case, the container must be dimensioned so that it can accommodate the liquid pressure and all other loads acting on it.
  • the storage container 10 is provided with a lining which covers the bottom 11 and the side wall 13 of the container and is designated in its entirety by 15.
  • the lining 15 also surrounds the supports 14, which are arranged distributed in the interior 16 of the container and together with the peripheral wall 13 support the ceiling 12 of the container.
  • In the ceiling 12 of the container there is an entry opening 17 which is lined with a metal socket 18 which, in the exemplary embodiment shown, extends over the container ceiling 12 protrudes.
  • a probe can be arranged in this access opening 17 or at another location of the container, which extends down to the bottom 11 of the container and is connected to the monitoring space of the container lining, as is known per se and is therefore not shown in detail here.
  • the lining 15 consists of an outer jacket 19, an inner jacket 20 and a profiled surface element 21 arranged between the outer jacket 19 and the inner jacket 20, which keeps the outer jacket 19 and the inner jacket 20 at a mutual distance from one another, but also connects with each other.
  • a primer made of unsaturated polyester is applied, on which the outer jacket is then applied in several layers with glass fiber interposed, so that there is a glass fiber reinforced polyester laminate that covers the entire surface of the concrete wall of the storage container connected is.
  • the profiled surface element consists of an aluminum foil which has a multiplicity of protrusions shaped in the form of hemispheres.
  • Metal foils profiled in this way are known as "ball impact foils" and are described in more detail, for example, in the above-mentioned DE-GM 19 74 383.
  • This spherical impact film with its hemispherical protruding knobs 21a is glued to the inner surface of the outer casing 19 or anchored in this surface in another way, for example pressed into the not yet hardened polyester plastic of the outer casing, which then develops a good adhesive effect when hardened and holds the profiled surface element 21 .
  • the inner jacket 20 is then applied to the front surface 21b of the profiled surface element 21 facing the interior 16 of the storage container.
  • the inner jacket 21 lies almost on the entire surface of the surface element 21 and is connected to the entire surface thereof.
  • a carbon fiber fleece 22 is embedded in the surface 20a of the inner shell 20 facing the container interior 16 such that it is essentially on the inner surface 20a of the inner shell 20, but is nevertheless firmly anchored to this inner shell 20.
  • the carbon fiber fleece is worked into the not yet hardened, sticky polyester resin with a spiked roller and thereby pressed in at certain points, so that the polyester resin of the inner jacket 20 partially reaches the surface 22a of the carbon fiber fleece 22 and this is connected to the under the Carbon fiber fleece lying plastic inner jacket holds on this.
  • the carbon fiber fleece 22 is then sealed on the surface facing the interior 16 with a layer 23 of a non-tacky, unsaturated polyester resin, so that there is a smooth inner surface.
  • the profiled surface element 21 ends just above the highest liquid level 24 in the container 10.
  • the outer casing 19 and the inner casing 20 are glued to one another over their entire surface and in the corner 25 of the container wall 13 and the container ceiling 12
  • FIG. 5 there is a circumferential groove 26 in the upper corner 25 between the container wall 13 and the container ceiling 12, into which the upper edge 27 of the lining 15 is drawn and anchored with a synthetic resin cement 28.
  • the synthetic resin putty 28 completely fills the groove 26, which is expediently sharp-edged so that the lining 15 is securely held on the edge 26a of the groove 26.
  • arresters 29 and 30 are provided under the carbon fiber fleece 22.
  • These arresters are metal strips, preferably made of thin copper sheet, which are arranged at a lateral distance from one another and of which the one arrester 29 runs at the bottom 11 of the container and from which the other arrester 30 in a vertical position and at a lateral distance from one another on the wall of the container 10 run.
  • the arrester tapes 29 and 30 are glued to the inner surface of the inner jacket 20 and are led upwards beyond the highest liquid level 24, where they are connected to an upper busbar 31 which is embedded in the plastic of the inner jacket 20 and on the inside around the entire storage container walks around.
  • the same busbar 32 is located a few centimeters above the container bottom 11 and, like the upper busbar 31, is embedded in the inner jacket 20.
  • the arrester 30 and also the arrester 29 laid in the ground are also connected in an electrically conductive manner to this lower collecting conductor, which, like the upper collecting conductor 31, is a circumferential copper strip.
  • the upper busbar 31 is also connected in an electrically conductive manner to the metal socket 18 of the entry opening 17 with a well-conductive, expediently flexible metal band 34, a so-called “cooler band”. If this metal socket 18 is concreted into the container ceiling 12 and the container 10 is embedded in the ground, this also results in a connection to the ground potential.
  • the profiled surface element can also be designed differently and it is possible to use other derivatives for the electrostatic dissipation from the carbon fiber fleece to the earth potential. It is also possible to connect to earth potential in another way.
