Definitions

  • the invention relates to a tank for liquids, in particular for chemically aggressive liquids according to the preamble of patent claim 1.
  • tanks are used for the storage and transportation of liquids. There are basically two types of construction known for tanks.
  • the tanks of the first type of construction are made of the most resistant material possible, e.g. stainless steel, polyethylene, polypropylene or concrete, which has sufficient mechanical and thermal resistance.
  • the tanks of this type of construction can be single-walled or double-walled.
  • the tank walls simultaneously form the supporting structure and the boundary between the tank interior and the environment.
  • the tanks of the second type of construction have an outer, thermally and mechanically resistant, supporting structure.
  • the supporting structure is protected by an additional coating or lining against the influences of the container contents or against the liquids entering the tank from outside.
  • the additional coating or lining is not part of the load-bearing structure.
  • the first synthetic resin layer When the first synthetic resin layer has hardened, it is covered with a second synthetic resin layer.
  • Such coatings have the disadvantage that no leak monitoring device can be integrated into them.
  • there is a risk that the coating will become detached from the container wall over time if chemically aggressive liquids are stored in the container that attack the synthetic resin.
  • a leak monitoring device For tanks of the first design type, a leak monitoring device must cover the entire surface of the tank in order to be able to reliably detect leaks. However, this is difficult to implement technically.
  • a tank with an integrated leak monitoring device is, for example, the subject of the patent specification GB 1,560,400 (publication date 6.2.1980).
  • This tank is barrel-shaped and double-walled. Both its inner and outer walls are made of glass fiber reinforced plastic.
  • a leak monitoring room is formed between the two walls. This space is filled with an air and liquid permeable filling.
  • the filling can be made of synthetic resin. It is non-positively connected to the inner and outer wall.
  • a tank with a multi-layered wall is the subject of the disclosure document DE 44 39 040 (disclosure date May 9, 1996). That tank has a rotationally symmetrical shape.
  • the tank wall is made up of four layers.
  • the outermost layer consists of a solid, non-foamed polymer, the subsequent layer of open-cell foamed polyurethane, the next layer of solid polyurethane and the innermost layer of solid polyamide.
  • the layers are non-positively connected.
  • the second outermost layer of open-cell, foamed polyurethane forms a leak monitoring room.
  • Another possibility is to arrange at least one liquid sensor in the drip pan.
  • the benefit of such an arrangement is, however, small, since a leak can only be determined when the tank is already damaged.
  • a coating can be produced by spraying plastic onto the inside of the tank walls.
  • Linings are usually produced by assembling them from a large number of small, easy-to-handle, plate-shaped semi-finished products made of plastic or rubber on the inside of the tank walls.
  • Another possibility is to weld many small plastic or rubber sheets into one large sheet.
  • the large panels are attached to the inside of a wall element.
  • Screws have the disadvantage that the cladding plates have to be provided with holes for receiving the screws. This Holes are not always completely sealed by the screws. It is therefore common for liquid to penetrate buses between a screw and the interface of the corresponding hole. Adhesives have the disadvantage that they can be dissolved if a chemically aggressive liquid penetrates between the lining and the tank wall.
  • the lining can leak.
  • the connection points between the individual lining plates and the bottom area of the lining are particularly susceptible to leaks. If chemically aggressive liquids get behind the lining, they also attack the tank wall.
  • the tank may leak over time. If a drip pan is used, the liquid emerging from the tank flows into the drip pan.
  • patent specification WO 1/02562 proposes to provide the lining with a thin protective layer on the inside.
  • the protective layer can consist of epoxy resin, for example.
  • leak monitoring devices are known for tanks of the second type of construction, with the aid of which leaks in the lining can be detected before the tank walls are attacked. Because the lining can in principle leak at any point, a reliable leak monitoring device must enclose the entire outer surface of the lining with a network of sensors.
  • These sensors are embedded in a substrate, for example.
  • the installation of the sensors is usually carried out after the supporting structure of the tank has been completed.
  • Such Le ⁇ küberwachungsvorri ⁇ htitch are very expensive to manufacture and correspondingly expensive.
  • the subject of published patent application DE 40 09 086 (publication date September 26, 1991) is, for example, a tank with a supporting structure made of metal or concrete and an inner lining made of a two-layer film.
  • the outer layer of this film is made of polyethylene, the inner layer of aluminum.
  • the contact side of the film has nubs, so that a space is created between the film and the supporting structure.
  • a leak warning device and a hose system for withdrawing liquid are arranged in this intermediate space.
  • a large number of sensors are also required for reliable tank monitoring in this tank.
  • this published specification does not describe a solution for the connection between the inner lining and the supporting structure.
  • the patent specification CH 672 110 (publication date October 31, 1989) proposes a standing tank with a double bottom. A cavity is formed between the two floors, which can be used for monitoring the leak.
  • the upper floor consists of a laminate, which is formed from a knobbed film and a synthetic resin layer.
  • the walls of this tank remain unprotected and are therefore very susceptible to leaks.
  • Several sensors are also required for the leak monitoring of the floor.
  • Patent CH 664 745 (publication date March 31, 1988) proposes, for example, a lining for liquid tanks, which consists of a double film. An airtight space is formed between the two foils, which is filled with an air-permeable foam layer serving as a spacer. The room is placed under vacuum for leak monitoring and monitored with a vacuum monitoring device. This lining is not very stable and is therefore unsuitable for larger tanks.
  • the DE 41 35 600 (publication date May 6, 1993) and the patent specification WO 93/0904 (publication date May 13, 1993) describe a storage container for liquid and / or solid chemical precipitants with a wall made of any solid support material with an inner surface Polyethylene lining.
  • This lining has a large number of knobs on the outside.
  • the wall can consist of a hardenable material in which the knobs of the lining are embedded.
  • This inner lining also has a plurality of knobs on its outer side, which abut the inner wall of the outer lining.
  • the space between the inner and outer lining is sealed airtight and connected to a vacuum monitoring device. It is placed under vacuum for leak monitoring.
  • connection between the inner lining and the container wall in this tank is based only on the frictional forces that act between the knobs and the hardened wall material.
  • the connection is therefore not sufficiently resilient.
  • the object of the present invention is therefore to create a tank for liquids, in particular for chemically aggressive liquids, which is equipped with a reliable, inexpensive leak monitoring device and the lining of which is permanently attached to the tank walls.
  • the object is achieved with the aid of the features of claim 1 according to the invention.
  • the supporting wall of the proposed tank is formed by at least three plate-shaped, preferably made of concrete wall elements.
  • the wall elements essentially have the shape of large, flat cuboids or cambered plates. They are usually several meters long and several meters high. Furthermore, they are all of the same size, so that the floor plan of the tank corresponds to a regular polyhedron.
  • a vertical leak monitoring channel is formed on the inside of each connection point between two wall elements.
  • the lining of the tank walls consists of large plates. These plates are made of thermoplastic or rubber. One lining plate is provided for each wall element.
  • the lining panels are fastened to the inside of the wall elements by means of positive connections. The lateral edge sections of two adjacent lining panels do not overlap in a first type of training.
  • the bottom of the tank is also made of concrete. It has one or a few liquid collection points, which are lower than the other bottom areas. The liquid collection points are preferably in the outer edge area. A liquid sensor is arranged at each liquid collection point. Leakage monitoring channels extend along the bottom edge, which open into the liquid collection points. The vertical leak monitoring channels open into these leak monitoring channels.
  • the top of the concrete floor can either run horizontally or fall in the direction of the leak monitoring channels and the liquid collection points. In order to achieve the latter, the top of the base can be cambered or can be designed as an inclined plane.
  • the top of the floor can also be divided into several sections which are designed as inclined planes.
  • the concrete floor is covered with a floor covering.
  • This floor covering is formed by thin, welded plates or by a film made of thermoplastic or rubber. Spacers are arranged between the top of the floor and the floor covering, so that a space is created between the floor covering and the concrete floor, through which any escaping liquid can flow to the leak monitoring channels.

  • the leak monitoring device of the proposed tank In contrast to known leak monitoring devices, only a few sensors 14 are required for the leak monitoring device of the proposed tank. Nevertheless, it can be used to determine leaks before the load-bearing concrete structure of the tank is attacked or even destroyed. If the proposed leak monitoring device detects a leak, it can be searched for with the aid of a known high-voltage test device and then repaired. In order to repair a leak, a piece of a plastic plate is simply welded onto the corresponding lining plate 11 over the leak. The repair of the lining in the proposed tank is therefore very simple and correspondingly inexpensive. A protective trough is not necessary for the proposed tank. The lining and the load-bearing concrete structure form two interlocking, liquid-tight containers. The tank thus fulfills the legal requirements.
