Definitions
- the invention relates to a leak detection device for detecting leaks in the walls of containers according to the preamble of claim 1.
- a leak detection device for detecting leaks in the walls of containers according to the preamble of claim 1.
- Such a leak detection device is known from US Pat. No. 5,172,584.
- Such leak detection devices are important for the monitoring of storage containers and other containers in chemical plants, from which substances can escape, which can lead to environmental pollution or other damage.
- One of these dangers is the ingress of leaked liquid substances into the soil and groundwater.
- a leak detection device is known from US Pat. No. 5,172,584, in which a container is provided with a second base, which is attached either while penetrating the side wall of the container during the manufacture of the container or subsequently inside the container.
- This second partition forming a partition is made of steel, for example of steel plates welded together, and is welded to the side wall of the container, so that a tight interstitial space is created between the main base of the container and the inserted partition.
- This monitoring room is filled with a granulate of sand, gravel or porous organic material, and a leak detection detector is connected to the monitoring room.
- Multi-layer plastic sealing sheets are known for use in landfills (DE-OS 35 35 705), which contain, inter alia, a permeation-inhibiting layer made from a mixture of epoxy and polysulfite.
- the invention has for its object to develop a leak detection device of the type mentioned and a method for its manufacture, which are simple and inexpensive in their construction or implementation and with which existing containers can be retrofitted in a short time.
- a leak detection device according to the preamble of claim 1 is proposed, which according to the invention has the features mentioned in the characterizing part of claim 1.
- a method for producing and repairing a leak detection device according to the invention is characterized by the features of claim 8. Embodiments of this method are mentioned in claims 9 and 10.
- a leak detection device can be manufactured by using easy-to-process and repair-friendly materials, whereby the costs for installation and repairs are kept low and only short downtimes of the system are required for installation or repair.
- the invention is particularly suitable for monitoring the tightness of the bottoms of the large number of large flat-bottom tanks in which mineral oils and fuels are stored.
- the invention can be used for any container, including its side walls.
- the layer (partition) made of polysulfide is characterized by its high elasticity and density as well as its high chemical resistance, particularly against mineral oil products and fuels.
- a copolymer for example an epoxy resin
- an electrically conductive substance for example carbon, can also be added to the polysulfide layer.
- Figure 1 shows a section of a bottom wall of a container provided with a leak detection device according to the invention.
- a leak detection device for example, it can be a section of the bottom of a flat-bottom tank.
- the actual container base is designated by 1.
- a layer 2 of porous material is applied to this, which can consist, for example, of porous concrete, fillings of granules or minerals or metal or plastic mesh.
- a layer 3 of polysulfide is applied to this porous layer 2.
- a copolymer for example an epoxy resin, can be added to the polysulfide, so that the layer 3 is composed of two components.
- This layer can be applied to the porous filler material layer 2 in any manner, for example by painting, spraying, pouring or by tightly laying a film.
- the layer 3 delimits the monitoring space 4 filled with filler material 2 from the interior 9 of the container.
- the cover layer At its edge is the cover layer on the inner side wall 7 of the container sealed connected.
- the container wall In order to ensure that the cover layer adheres to the container wall 7, it must be pretreated with an adhesive primer.
- the container wall must first be cleaned and rust free. In flat-bottom tanks, it is sufficient to form a monitoring room 4 at the bottom of the tank, since a leak on the side walls of the tank can be easily detected. In principle, however, the side walls of the container can also be provided with a monitoring room of the type described.
- the monitoring room 4 is evacuated for the purpose of monitoring.
- This vacuum is monitored by a leak detection detector to be connected to the monitoring room, which can be of a known type and can operate, for example, optically, acoustically or electrically.
- the leak detector can be connected to the monitoring space, for example, via hoses, or the detector can be inserted directly into the wall of the container delimiting the monitoring space 4, for example by screwing.
- the partition consists of a carrier sheet 3a made of metal or plastic, which has knobs 6 directed towards the container bottom 1, with which it is supported on the container bottom 1.
- a layer 3b of the type described above made of polysulfide with or without an additional component of the type described above is applied to the side of the carrier web 3a facing the container interior.
- the layer 3b can also, as shown in FIG. 2, fill the knobs 6; however, the knobs can also be formed solidly from the material of the carrier layer 3a as part of this carrier layer.
- the knobs 6 are arranged essentially point-shaped, so that by no closed chambers can be formed within the interstitial space.
- the underlay can be pretreated (primed) with an adhesive primer.
- FIG. 3 shows an embodiment which is constructed similarly to the exemplary embodiment according to FIG. 2, but in which a separate carrier layer 3a for the polysulfide material is dispensed with.
- the polysulfide material in the form of a film itself is provided with knobs via which the forces acting on the partition wall are transmitted to the container bottom 1.
- the damaged part can be cut out and repaired by applying new cover layer material in the narrowly limited damaged area, the old cover layer forming a connection with the new layer.
- a further monitoring room 14 (FIG. 4) of the type described above can be built up on the undamaged partition 3 according to one of the exemplary embodiments described, and then the space created between the two partition walls 3 and 13 can be used as a monitoring room .
- the two monitoring rooms 4 and 14 are filled with porous filling material. In this way, despite a leak 8 in the container wall 1, for example at the bottom of the container, the container can be used after a short time and at low cost.
