Description
Schutzdecke für Tanks Die Erfindung betrifft eine Schutzdecke für it Tanks gelagerte Flüssigkeiten, vorzugsweise aus der Erdo'lgewinnungs- und Verarbeitungsindustrie, zur Verhütung von Entgasungs- und Wärmeverlusten sowie einer Entzündung.Protective cover for tanks The invention relates to a protective cover for Liquids stored in tanks, preferably from the oil extraction and processing industry, to prevent degassing and heat loss as well as ignition.
Verwandt werden in der Erdölindustrie zur Verrillgerung von Entgasungsverlusten leicht verdaml>fender Flüssigkeiten in stehenden Tanks bisher schwimmende Tankdecken aus Stahlblech. Are used in the oil industry to reduce degassing losses Liquids that evaporate easily in standing tanks have previously been floating tank ceilings made of sheet steel.
I)iese erfordern Spezialtanks und verursachen bettächtliche Konstruktionskosten, ferner haben sie deii Nachteil, durch ihre sperrige Hlechkonstruktion bei Tankl,ränden die Löscharbeiten zu erschweren.I) these require special tanks and cause considerable construction costs, Furthermore, they have the disadvantage, due to their bulky steel construction, edges on tanks to complicate the extinguishing work.
I)iese Nachteile sowie hohe Baukosten und konstruktive Schwierigkeiten lassen sich durch die Anwendung von Festschaumdecken aus einem verschäumten Kunststoff in den Tanks üblicher Konstruktion beseitigen. Die Festschaumdecke wird vor dem Füllen des Tanks auf dem Tankboden durch Verkleben oder Verschweißen einzelner vorgefertigter Schaumstoffstreifen oder -segmente zusammengesetzt, oder die Decke wird durch Aufspachteln oder Aufspritzen auf eine den Tankquerschnitt bedeckende Unterlage (Olpapier) hergestellt und nach diesem Verfahren beim Hereinlassen der Flüssigkeit mit dieser hochgehoben. Die elastische Schaumdecke ermöglicht eine feste Führung an der Tankwandung, so daß ein guter Abschluß gewährleistet ist. Falls Einbauten, z. B. Dampfschlangen o. ä., im Tank vorhanden sind, ist es erforderlich, über diese ein Netz aus Maschendraht zu verspannen, auf das sich die Festschaumdecke beim Entleeren des Tanks auflegt. Die Art der Ausbildung der Schaumdecke wechselt nach den jeweiligen Erfordernissen. I) these disadvantages as well as high construction costs and constructional difficulties can be achieved by using rigid foam blankets made from foamed plastic eliminate in the tanks of usual construction. The rigid foam blanket is in front of the Filling the tank on the tank bottom by gluing or welding individual prefabricated ones Foam strips or segments put together, or the ceiling is made by spatula or spraying onto a base (oil paper) covering the tank cross-section and according to this procedure, when the liquid is let in, it is lifted up with it. The elastic foam cover enables a firm guidance on the tank wall, see above that a good deal is guaranteed. If internals, e.g. B. steam coils etc., are present in the tank, it is necessary to use a network of wire netting over this to brace, on which the rigid foam ceiling when Emptying the Hangs up tanks. The type of formation of the foam blanket changes according to the respective Requirements.
Soll nur eine Entgasung einer Flüssigkeit verhütet werden, so genügt eine Schaumdecke von I bis 2 cm Dicke. Sollen aber außerdem Wärmeverluste vermieden werden, so ist eine stärkere Decke zu verwenden, entsprechend der Wärmeleitfähigkeitszahl des Schaumes. Den Anforderungen als Brandschutzmittel wird die Festschaumdecke schon durch die Verhütung des Verdampfens größerer Mengen leichtbrennbarer Gase gerecht; weiterhin ist der Schaum aus nicht brennbarem Material aufgebaut und enthält gegebenenfalls als Porenfüllung ein Schutzgas (CO2, N2). Diese Eigenschaften geben der Festschaumdecke aus Kunststoffen vielfache Anwendungsmöglichkeiten und technische und kostenmäßige Vorziige vor bisher bekannten Verfahren. If only degassing of a liquid is to be prevented, then it is sufficient a foam blanket 1 to 2 cm thick. But should also avoid heat losses a thicker blanket is to be used, according to the coefficient of thermal conductivity of the foam. The rigid foam ceiling already meets the requirements as a fire protection agent fair by preventing the evaporation of large quantities of easily flammable gases; furthermore, the foam is made up of non-combustible material and optionally contains A protective gas (CO2, N2) as pore filling. These properties give the rigid foam ceiling made of plastics multiple uses and technical and cost-related Advantages over previously known methods.
