Abstract:
The invention relates to a tank (10) for storing compressed gas having a pressure of at least 15 Mpa, a casing layer (11) which encloses the hollow space (13) provided for storing the compressed gas, and at least one connection for loading and/or unloading the tank (10). In order to decrease the weight of the tank, the casing layer (11) can be constructed of plastic and/or a fiber material. According the invention, supporting elements (30) which are connected to the casing layer (11) are provided in the hollow space (13) of the tank (10) such that the tank (10) can be constructed in any geometric shape and can especially store gasses under high pressure. The supporting elements (30) can be constructed as filaments which are guided through the corresponding guiding canals (31). As a result, the supporting elements (30) assume the function of a seam. A liner (14) preferably constructed of plastic can be arranged on the inner surface (12) of the casing layer (11) in order to additionally seal the tank (10).
Abstract:
Generally there is described herein two versions of a thermally conductive porous inner structure for a tank. In the first embodiment a closed tank (10) is accessed through an orifice and an injection tube is inserted to spray a coat of adhesive on the inner surface. Next a foil ribbon is fed through a tube (40) into the tank, allowing it to coil and fold therein until the tank is filled. When the adhesive (38) hardens a thermally conductive mesh-like structure results. In the second embodiment a tube is inserted through the tank opening and a mixture of ribbon segments and quick setting adhesive are injected. These segments fill the tank with a porous structure to create a mesh-like thermal insert. With either embodiment, a reinforcing liner can also be installed through the orifice. Resin, plastic, or fiberglass/resin mixture can be sprayed into the tank to form the liner, or plastic can be inserted and centrifugally molded within the tank. In the manufacturing or remanufacturing process, the position of the injection tube is controlled in coordination with the weight of the tank, gradually being withdrawn as the tank weight increases. Once the desired weight is reached, the injection is terminated and the injection tube is withdrawn.
Abstract:
The present invention provides a method and a system for handling gaseous fuels using sub-tanks (3) as gas emitting entities within a fuel tank (1). In particular the invention provides a system comprising an exchanger unit (2) for filling filled sub-tanks (3) to, and removing emptied sub-tanks (3) from, the fuel tank (1). Thanks to the invention the filling and removal is fast, efficient and safe.
Abstract:
The invention relates to an operating gas system (1a, 1b) for an underwater vehicle, particularly for a submarine or an unmanned underwater vehicle, comprising a fuel cell system (3) and an operating gas container (5) connected in terms of flow to the fuel cell system (3). In order to achieve simple and efficient storage of boil-off gasses (BO), a gas-receiving device (7) is also provided and is connected to the operating gas container. The gas-receiving device (7) contains a sorbent (9, 19) for receiving boil-off gas (BO) from the operating gas container (5). The boil-off gas (BO), which is produced in the operating container (5) with the operating gas (BG) for the fuel cell system and which cannot be consumed directly in the fuel cell reaction, is therefore collected and stored with the aid of the sorbent (9, 19) in the gas-receiving device (7).
Abstract:
In einem Tank zur Lagerung kryogener Flüssigkeiten oder lagerfähiger Flüssigkeiten für einen Einsatz in Weltraumexperimenten unter den Bedingungen der Schwerelosigkeit sind zur sicheren Trennung von Gas- und Flüssigkeitsphase Strukturen aus einem schwammartigen Material, insbesondere aus einem Metallschaum, angeordnet, deren Gesamtporenvolumen größer gewählt ist als das Volumen der aufzunehmenden Flüssigkeit. Die Strukturen sind als ineinander liegend angeordnete ringförmige Platten ausgebildet, die im Inneren der zylindrisch ausgebildeten Tanks angeordnet sind. Im Zentrum des Tanks ist eine Entnahmevorrichtung angeordnet, die sich vor den Porenöffnungen des Metallschaums befindet. Für Weltraumexperimente unter Schwerelosigkeit, die den Einsatz kryogener Flüssigkeiten erfordern, kann der Tank zusammen mit einem vorgeschalteten Vorratstank in einem Kryostaten angeordnet werden, der mit einer Heizvorrichtung versehen ist.
Abstract:
Safe storage of volatile compounds or elements is provided by utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials. Such configurations may provide storage of hazardous, liquefied gases in closed-cell foam material. Release of gas/liquid from the foam is restricted by the need for the gas to diffuse through the closed cells. Because rapid release is prevented, storage safety is greatly improved.
Abstract:
Large amounts of hazardous goods, especially liquid ones such as fuel, may be carried in safety containers, whether tank semitrailers, oil tankers, containers for hazardous goods or aircraft, and be transported with practically no risk for the environment, by completely filling the inside (10) of the container with glass wool, so that the hazardous materials or other fillings dispersed therein may not escape or be somehow spilled in the environment. The liquid components, for example hydrocarbons, are absorbed and held by a dense, water-proofed latticework (15), so that no oxygen can reach them. They are thus protected against explosions and spillage in the environment. At the same time, a safety container of this type acts as a kind of safety buoy, preventing water from entering the inside (10) of the container, so that the kerosene, gasoline or oil contained therein further increase buoyancy. As a whole, a simplification of the safety container design and a considerable increase in safety may be noted.
