Abstract
Die Erfindung betrifft eine Vorrichtung zur Erzeugung eines Atmosphärendruck-Plasmas mittels einer Bogenentladung. Abweichend vom bisher bekannten Stand der Technik wird die Bogenentladung mittels eines als Kathode wirkenden Piezoelements mit Primär- und Sekundärseite erzeugt.The invention relates to a device for generating an atmospheric pressure plasma by means of an arc discharge. Notwithstanding the prior art, the arc discharge is generated by means of acting as a cathode piezoelectric element with primary and secondary side.
Description
Die
Erfindung betrifft eine Vorrichtung zur Erzeugung eines Atmosphärendruck-Plasmas.
Eine solche Vorrichtung ist aus der
Diese bekannte Vorrichtung weist eine Reihe von Nachteilen auf. Zunächst einmal wird eine hohe Zündspannung von mehreren kV benötigt; die Betriebsspannung bewegt sich ebenfalls im kV-Bereich. Die in der Folge entstehende Bogenentladung – ein direkter Lichtbogen also – führt zu einer hohen Wärmeentwicklung und einem Absputtern der Elektroden. Weitere Nachteile sind die hohen Kosten und die Baugröße dieser Vorrichtung.These known device has a number of disadvantages. First once a high ignition voltage of several kV is required; the operating voltage also moves in the kV range. In the Resulting arc discharge - a direct arc So - leads to a high heat development and a sputtering of the electrodes. Other disadvantages are the high cost and the size of this device.
Aufgabe der Erfindung ist es, eine Vorrichtung zur Erzeugung eines Atmosphärendruck-Plasmas anzugeben, die diese Nachteile nicht aufweist und insbesondere auch mit Niederspannung betrieben werden kann.task The invention is an apparatus for generating an atmospheric pressure plasma indicate that does not have these disadvantages and in particular also can be operated with low voltage.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des ersten Patentanspruches gelöst. Die Unteransprüche betreffen vorteilhafte Weiterbildungen der Erfindung.These Task is performed by a device with the characteristics of the first Claim solved. The dependent claims relate advantageous developments of the invention.
Die allgemeine Idee der Erfindung besteht darin, zur Erzeugung des Plasmas ein Piezoelement mit Primär- und Sekundärbereich zu verwenden. Dabei erfolgt die Ansteuerung des Primärbereichs des Piezoelementes mit Niederspannung und Hochfrequenz. In der Folge wird das Plasma durch die Feldüberhöhung auf der Fläche des Sekundärbereichs des Piezoelements gezündet. Erfindungsgemäß erfolgt die Plasmaführung durch Gegenelektrode und eine Gasströmung. Durch die Gasströmung tritt das Plasma aus der Vorrichtung aus.The general idea of the invention is to generate the plasma a piezo element with primary and secondary area to use. In this case, the activation of the primary area takes place of the piezo element with low voltage and high frequency. Subsequently the plasma is due to the field elevation on the Area of the secondary area of the piezoelectric element ignited. According to the invention, the Plasma guidance through counter electrode and a gas flow. Due to the gas flow, the plasma exits the device out.
Ein
Piezoelement zur Erzeugung eines Plasmas ist bereits aus der Veröffentlichung
Eine
weitere Anordnung, auch als Piezotransformator bezeichnet, mit einem
solchen Piezoelement mit einem Primär- und einem Sekundärbereich,
dort als Anregungszone und Hochspannungszone bezeichnet, ist aus
der
Bei beiden Veröffentlichungen dient das Piezoelement dazu, eine Plasmaentladung an der Oberfläche des Sekundärbereiches zu erzeugen. Bei der Erfindung hingegen ist eine Gegenelektrode vorgesehen; damit wird erfindungsgemäß eine Bogenentladung erzeugt und gerade nicht, wie nach dem Stand der Technik, ein flächiges Plasma auf der Oberfläche des Sekundärbereichs des Piezoelementes.at In both publications, the piezoelement serves to a plasma discharge on the surface of the secondary region to create. In the invention, however, is a counter electrode intended; Thus, according to the invention, an arc discharge produced and not just, as in the prior art, a planar Plasma on the surface of the secondary area of the piezo element.
Nach
einem weiteren Merkmal der Erfindung ist im Gegensatz zur eingangs
genannten
Die erfindungsgemäße Vorrichtung weist eine Reihe von Vorteilen gegenüber den bekannten Lösungen auf. Zunächst einmal benötigt sie eine nur niedrige Betriebsspannung im Bereich von vorzugsweise 5...230 V. Ferner ist sie durch eine niedrige Plasmatemperatur gekennzeichnet; ein Absputtern und ein Abbrand der Kathode sind damit nahezu ausgeschlossen. Schließlich ist die erfindungsgemäße Vorrichtung preisgünstig herstellbar, da keine Hochspannungsquelle mehr erforderlich ist und weist zudem eine nur geringe Baugröße auf.The Inventive device has a row of advantages over the known solutions on. First of all, it only needs a low one Operating voltage in the range of preferably 5 ... 230 V. Further is they are characterized by a low plasma temperature; a sputtering and Burning of the cathode are thus almost impossible. After all the device according to the invention is inexpensive Can be produced because no high voltage source is required and also has a small size.
Die erfindungsgemäße Vorrichtung und ihre wichtigen Bestandteile sollen nachfolgend an Hand von Ausführungsbeispielen näher erläutert werden. Es zeigen:The Inventive device and its important Components are to be described below with reference to exemplary embodiments be explained in more detail. Show it:

Aus diesen Beispielen ist ersichtlich, dass bei der Erfindung das Plasma durch eine Bogenentladung zwischen zwei Elektroden, d. h. eine Funkenstrecke gebildet wird. Dabei bildet der Sekundärbereich der Piezokeramik jeweils die eine Elektrode; nämlich die Kathode, die Gegenelektrode liegt jeweils auf Erdpotential. Bei der Erfindung ist also die Kathode nicht, wie aus dem Stand der Technik bekannt, als passives Element ausgebildet, etwa als stabförmige, metallische Elektrode im Zentrum eines Rohres, sondern stellt ein aktives Element dar, in dem eine (am Primärbereich angelegte) Niederspannung in eine Hochspannung (im Sekundärbereich) transformiert wird.Out From these examples it can be seen that in the invention the plasma by an arc discharge between two electrodes, d. H. a spark gap is formed. In this case, the secondary region of the piezoceramic forms each one electrode; namely the cathode, the counter electrode lies at earth potential. In the invention, therefore, the cathode not, as known in the art, as a passive element designed as a rod-shaped, metallic electrode in the center of a pipe, but represents an active element in which a (applied to the primary area) low voltage transformed into a high voltage (in the secondary area) becomes.
Mit der erfindungsgemäßen Vorrichtung ist es erstmals gelungen, die Vorteile einer Bogenentladung und in der Folge eines ausgeblasenen Plasmastrahls mit den Vorteilen eines Piezoelementes mit Primär- und Sekundärbereich zu verbinden.With The device according to the invention is the first time succeeded, the advantages of an arc discharge and in the consequence of a blown plasma jet with the advantages of a piezoelectric element to connect with primary and secondary area.
