Abstract

The expansion machine (1) is connected to a magnetic field-generating rotor (2), where the power is generated by the magnetic field. One-piece fully-hermetic housing (3) is formed externally. A force-decreasing device is provided as magnetic coupling, which has the rotor and a magnetic field receiving unit (4). The force-decreasing device is an electrical generator, which releases the electrical current outward. A power receiver (5) is installed on the outside of the housing.

Stand der TechnikState of the art

ORC Expansionsmaschinen sind derzeit nicht mit Magnetfeld Leistungskupplung erhältlich, bei der das voll-hermetische Maschinengehäuse, die Leistungskupplung durchquert.ORC expansion machines are currently not available with magnetic field power coupling, where the full-hermetic machine housing, traversing the power clutch.

Technische Beschreibungtechnical description

Bei der Erfindung handelt es sich um eine Expansionsmaschine (1) für Gase und Dampfe, insbesondere für ORC Prozesse. Als ORC Anlage/ORC Prozess/ORC Kreislauf wird dabei eine technische Vorrichtung bezeichnet, die als Energieerzeugungsanlage auf Grund eines thermodynamischen Kreisprozesses (Carnot-Kreisprozess) ausgeführt ist. Dabei arbeitet die Energieerzeugungsanlage nach einem Kreisprozess, der als Ericsson-Kreisprozess, Clausius-Rankine-Kreisprozess, Joule-Kreisprozess, Kalina-Kreisprozess, Stirling-Kreisprozess oder Organic-Rankine-Cycle bekannt ist. Symbolisch wird hierfür, in allen Beschreibungen, der Begriff „ORC” oder „ORC Prozess” verwendet.The invention is an expansion machine ( 1 ) for gases and vapors, in particular for ORC processes. An ORC system / ORC process / ORC circuit is a technical device which is designed as a power generation system on the basis of a thermodynamic cycle (Carnot cycle). The energy production plant works according to a cycle process known as the Ericsson cycle, the Clausius-Rankine cycle, the Joule cycle, the Kalina cycle, the Stirling cycle, or the Organic Rankine cycle. Symbolically, in all descriptions, the term "ORC" or "ORC process" is used.

Die Erfindung besteht im wesentlichen aus einer Expansionsmaschine (1), die an einen Magnetfeld erzeugenden Rotor (2) gekoppelt ist. Diese beiden Bauteile sind in einem Gehäuse (3) verbaut, das aus einem einzigen, nicht ohne Zerstörung trennbaren, Bauteil besteht.The invention consists essentially of an expansion machine ( 1 ) connected to a magnetic field generating rotor ( 2 ) is coupled. These two components are in a housing ( 3 ), which consists of a single component which can not be separated without destruction.

Dabei ist die Expansionsmaschine als Dampfschraube, Scrollexpander, Turbine oder als Kolbenmaschine ausgelegt. Der Rotor erzeugt ein Magnetfeld entweder durch Permanent-Magnete, elektrische Spulen oder Induktion von Feldern. Das Gehäuse ist ein voll-verschweißtes Metallgehäuse oder ein Guss-Bauteil. Die Anschlüsse für Druckgas (7) und Rückstrom (8) befinden sich entweder an den Stirnseiten oder seitlich der Expansionsmaschine.The expansion machine is designed as a steam screw, Scrollexpander, turbine or piston machine. The rotor generates a magnetic field either through permanent magnets, electric coils or induction of fields. The housing is a fully-welded metal housing or a cast component. The connections for compressed gas ( 7 ) and reflux ( 8th ) are located either on the front sides or on the side of the expansion machine.

Der Vorteil liegt in der Vermeidung von Leckstellen (undichte Stellen) an der Trennstelle, das verschiedene Bauformen der Magnetkupplung verbaut sein können um verschiedene Magnetfeldabnehmer auf der Außenseite antreiben zu können sowie einer besseren Integrierbarkeit in, aus dieser Maschine hergestellten, Folgeprodukte.The advantage lies in the avoidance of leaks (leaks) at the separation point, which can be installed different types of magnetic coupling to drive different magnetic field pickups on the outside and a better integrability in, produced from this machine, secondary products.
