Abstract
Description
Schaltschema sowie Bohrlochausstattung zur Nutzung der Erdwärme für Heizung, Warmwasserbereitung und industrielle Zwecke.Circuit diagram and borehole equipment for the use of geothermal energy for Heating, water heating and industrial purposes.
Beschreibung: Bohrungen müssen niedergebracht werden. Die Verrohrung der Bohrlöcher muß so erfolgen, daß aufbereitetes Wasser im äußeren Rohr hinabgepumpt wird und in der Mitte (inneres Rohr) erhitzt zur Erdoberfläche wieder aufsteigt (Fig. 1).Description: Boreholes need to be drilled. The piping the boreholes must be made in such a way that treated water is pumped down the outer pipe is heated and in the middle (inner tube) rises to the surface of the earth (Fig. 1).
Um Wärmeverluste weitgehendst auszuschalten, ist eine Isolierung des Innenrohres erforderlich. Auch würde ein mehrmaliges Umpumpen die Trägertemperatur erhöhen.In order to largely eliminate heat loss, the Inner tube required. Repeated pumping would also increase the carrier temperature raise.
Mehrere niedergebrachte Bohrungen - tiefenmäßig versetzt, um eine optimale Ausnutzung der Erdwärme zu erzielen - können mit einem Sammler verbunden werden. Von dort erfolgt dann über einen Verteiler die Weiterleitung des Wärmeträgers für die verschiedensten Einsatzzwecke wie Fernwärme- und Warmwasserversorgung in Ballungsgebieten usw. (Fig. 2).Several holes drilled - offset in depth by one to achieve optimal utilization of geothermal energy - can be connected to a collector will. From there, the heat transfer medium is passed on via a distributor for a wide variety of purposes such as district heating and hot water supply in Metropolitan areas, etc. (Fig. 2).
Da das Temperaturgefälle sehr niedrig ist müssen große Bohrtiefen angestrebt werden (technisch möglich, da in den Staaten Texas und Oklahoma, USA, schon Bohrungen bis an die 8.000-m-Grenze vorgenommen wurden).Since the temperature gradient is very low, great drilling depths are required (technically possible because in the states of Texas and Oklahoma, USA, bores have already been made up to the 8,000 m limit).
Bereits durchgeführte Probebohrungen im Bundesgebiet geben Aufschluß über Gesteinsformationen, somit scheiden Problembohrungen aus.Test drillings that have already been carried out in Germany provide information over rock formations, so problem bores are ruled out.
Ballungszentren sind bekannt, Wärmebedarf im voraus bestimmbar.Metropolitan areas are known, heat requirements can be determined in advance.
