The device shown in FIGS. 1 to 5 has a treatment room 1 through which the liquid to be treated flows. Inlet and outlet openings 2, 3 are provided for the inlet and outlet of the liquid to be treated. The direction of flow is arbitrary.

Der Behandlungsraum 1 liegt zwischen zwei Kαndensatorplatten 4, 5. Weiter sind im Bereich des Behandlungsraumes 1 zwei Schwingkreisspulen 6, 7 angeordnet, deren Magnetfeld den Behandlungsraum durchsetzt. Damit ist die im Behandlungsraum 1 befindliche Flüssigkeit sowohl der Einwirkung des durch die Kondensatorplatten 4, 5 gebildeten elektrischen Feldes als auch der Einwirkung des durch die Schwingkreisspulen 6, 7 gebildeten Magnetfeldes unterworfen.The treatment room 1 is located between two capacitor plates 4, 5. Furthermore, two resonant circuit coils 6, 7 are arranged in the area of the treatment room 1, the magnetic field of which passes through the treatment room. The liquid in the treatment room 1 is thus subjected both to the action of the electrical field formed by the capacitor plates 4, 5 and to the action of the magnetic field formed by the resonant circuit coils 6, 7.

Bei der Vorrichtung nach den Fig. 1 bis 5 sind die Kodnensatorplatten 4, 5, wie Fig. 5 zeigt, über die Schwingkreisspulen 6, 7 an eineIn the device according to FIGS. 1 to 5, the encoder plates 4, 5, as shown in FIG. 5, are connected to one via the resonant circuit coils 6, 7

Gleichspannungs-Hochspannungsquelle 8 angeschlossen, die ihrerseits über ihre Klemmen 9 mit elektrischer Energie, z.B. aus einem elektrischen Stromversorgungsnetz, versorgt wird. Die Hochspannungsquelle 8 ist im dargestellten Fall eine Kondensator-Sleichrichter-Kaskadenschaltung; es kommen auch andere Ausbildungen von Hochspannungsquellen in Frage, z.B. sog. Schaltnetzteile mit Hochspannungsausgang. Die durch die Kondensatoren 12 der die Hαchspannungsquellle 8 bildenden Kaskadenschaltung gebildete wirksame Gesamtkapazität ist in Fig. 5 durch einen einzigen Kondensator 14, der am Ausgang 10 der Hochspannungsquelle 8 liegt, dargestellt.DC high voltage source 8 connected, which in turn via its terminals 9 with electrical energy, e.g. from an electrical power supply network. The high-voltage source 8 is a capacitor-rectifier cascade circuit in the case shown; other designs of high voltage sources are also possible, e.g. so-called switching power supplies with high voltage output. The effective total capacitance formed by the capacitors 12 of the cascade circuit forming the high voltage source 8 is shown in FIG. 5 by a single capacitor 14 which is located at the output 10 of the high voltage source 8.

Ein elektrischer Leiter 15 führt von der einen Kondensatorplatte 4 über ein als Funkenstrecke 16 ausgebildetes Schalterelement zur anderen Kondensatorplatte 5; wenn die Funkenstrecke 16 anspricht, d.h. das durch diese Funkenstrecke gebildete Schalterelement schließt, wird über den Leiter 15 ein von der Kondensatorplatte 4 zur Kondenstorplatte 5 führender Stromkreis gebildet. Die Schlagweite der Funkenstrecke 16 ist mit einer Schraube 17, welche mit einer elektrisch isolierenden Handhabe 18 versehen ist, einstellbar. Auf diese Weise kann die Ansprechspannung des durch die Funkenstrecke 16 gebildeten Schalterelemenetes verändert werden.An electrical conductor 15 leads from one capacitor plate 4 via a switch element designed as a spark gap 16 to the other capacitor plate 5; When the spark gap 16 responds, ie the switch element formed by this spark gap closes, a circuit leading from the capacitor plate 4 to the capacitor plate 5 is formed via the conductor 15. The stroke distance of the spark gap 16 is adjustable with a screw 17, which is provided with an electrically insulating handle 18. In this way, the response voltage of the switch element formed by the spark gap 16 can be changed.

Wird der Hαchspannungsquel le 8 über die Klemmen 9 elektrische Energie zugeführt, baut sich am Ausgang 10 der Hochspannungsquelle, dessen Ausgangskapazität durch den Kondensator 14 dargestellt ist, eine hohe Gleichspannung auf. Diese Hochspannung liegt gleichzeitig an den Kondensatorplatten 4 und 5. Sobald der Wert dieser Hochspannung die Zündspannung der Funkenstrecke 16 erreicht, wird diese leitend, und es erfolgt eine schlagartige Entladung der in der Hαchspannungsquelle gespeicherten Energie über die Schwingkreisspulen 6, 7, wodurch mit diesen Spulen während eines kurzen Zeitabschnittes ein starkes Magnetfeld, das auf die im Behandlungsraum 1 befindliche Flüssigkeit einwirkt, erzeugt wird. Es kann dabei angenommen werden, daß die Entladung eine rasch abklingende Schwingung erzeugt. Dieser Schwingung ist eine weitere Schwingung mit wesentlich höherer Frequenz überlagert, welche in dem durch die Kapazität 20 der Kondensatorplatten 4, 5 und dem Leiter 15 gebildeten Schwingkreisteil bei leitender Funkenstrecke 16 entsteht.If the high-voltage source 8 is supplied with electrical energy via the terminals 9, a high direct voltage builds up at the output 10 of the high-voltage source, the output capacitance of which is represented by the capacitor 14. This high voltage is at the same time on the capacitor plates 4 and 5. As soon as the value of this high voltage reaches the ignition voltage of the spark gap 16, it becomes conductive, and there is an abrupt discharge of the energy stored in the high voltage source via the resonant circuit coils 6, 7, thereby using these coils a strong magnetic field, which acts on the liquid in the treatment room 1, is generated for a short period of time. It can be assumed that the discharge produces a rapidly decaying oscillation. This oscillation is superimposed on a further oscillation with a significantly higher frequency, which arises in the part of the oscillating circuit formed by the capacitance 20 of the capacitor plates 4, 5 and the conductor 15 with a conductive spark gap 16.

Nach dem Abklingen der vorerwähnten Schwingungen verliert die Funkenstrecke 16 ihre Leitfähigkeit und es kommt erneut zu einem Auf aau einer Hochspannung am Ausgang 10 der Hochspannungsque l l e 8. Dieser Spannungsaufbau erfordert einen wesentlich längeren Zeitraum als die Entladung der in der Hochspannungsquelle 8 gespeicherten Energie, und es wird demgemäß die im Behandlungsraum 1 befindliche Flüssigkeit während kurzer Zeitabschnitte der Einwirkung eines durch die Spulen 6, 7 erzeugten Magnetfeldes unterworfen, und es sind diese kurzen Zeitabschnitte von längeren Pausen getrennt. Das elektrische Hochspannungsfeld, dem die im Behandlungsraum 1 befindliche Flüssigkeit gleichfalls unterworfen ist, besteht entsprechend dem verhältnismäßig langsamen Spannungsaufbau am Ausgang 10 der Hαchspannungsquel le 8 aus einer langsam veränderlichen Komponente und aus einer hochfrequenten Komponente, die von den vorstehend erörterten Schwingungsvorgängen herrührt.After the abovementioned vibrations have subsided, the spark gap 16 loses its conductivity and there is again a build-up of a high voltage at the output 10 of the high-voltage source 8. This voltage build-up requires a considerably longer period of time than the discharge of the energy stored in the high-voltage source 8, and accordingly the liquid in the treatment room 1 is subjected to the action of a magnetic field generated by the coils 6, 7 for short periods of time, and these short periods of time are longer Breaks separated. The electrical high-voltage field, to which the liquid in the treatment room 1 is also subjected, consists, according to the relatively slow voltage build-up at the output 10 of the high-voltage source 8, of a slowly changing component and of a high-frequency component which results from the oscillation processes discussed above.

Das den Behandlungsraum 1 bildende Gefäß ist bei dem in den Fig. 1 bis 5 dargestellten Beispiel aus zwei aus Isolierstoff bestehenden Dαsenhälften 22, 23 gebildet, in deren Wände außer den Kondensatorplatten 4, 5 auch die Schwingkreisspulen 6, 7 eingebettet sind. Die Dαsenhälften 22, 23 sind zwischen zwei aus Metall bestehende Spannplatten 24, 25 eingefügt und werden durch diese aneinander gepreßt, wobei der Ringspalt zwischen den Dosenhälften durch einen Dichtungsring 26 geschlossen ist. Die Spannplatten 24, 25 werden ihrerseits mit Schrauben 27 zusammengehalten. Auf der Innenseite der Dαsenhälften ist ein den Behandlungsraum 1 zu einem U-förmigen Durchfluß formender Steg 28 vorgesehen, und es liegen die Zu- und Abflußöffnungen 2, 3 des Behandlungsraumes einander benachbart je auf einer Seite dieses Steges 28. Die Kondensatorplatten 4, 5 reichen über den ganzen Behand l ungsraum 1.The vessel forming the treatment room 1 is formed in the example shown in FIGS. 1 to 5 from two nozzle halves 22, 23 made of insulating material, in the walls of which, in addition to the capacitor plates 4, 5, the resonant circuit coils 6, 7 are also embedded. The nozzle halves 22, 23 are inserted between two metal clamping plates 24, 25 and are pressed against one another by this, the annular gap between the can halves being closed by a sealing ring 26. The clamping plates 24, 25 are in turn held together by screws 27. On the inside of the nozzle halves there is a web 28 forming the treatment room 1 into a U-shaped flow, and the inlet and outlet openings 2, 3 of the treatment room are adjacent to each other on one side of this web 28. The capacitor plates 4, 5 are sufficient over the entire treatment room 1.

Das in den Fig. 6 bis 9 dargestellte Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung ist dem vorstehend erörterten Ausführungsbeispiel nach den Fig. 1 bis 5 ähnlich ausgebildet.The embodiment shown in FIGS. 6 to 9 is a device according to the invention 1 to 5 similar to the embodiment discussed above.

Es ist bei dem Ausführungsbeispiel nach den Fig. 6 bis 9 der Behandlungsraum 1 durch ein einteiliges, aus Isolierstoff bestehendes Gefäß 29 gebildet, in dem die Zu- und Abflußöffnungen 2, 3 vorgesehen sind, und in dessen isolierende Wände die Kondensatαrplatten 4, 5 eingebettet sind. Die zur Bildung des den Behandlungsraum 1 durchsetzenden Magnetfeldes vorgesehene Spule 30 ist im Bereich des Steges 28, der aus dem Behandlungsraum 1 einen U-förmigen Durchflußweg formt, angeordnet und so placiert, daß die Feldrichtung des Magnetfeldes dieser Spule im Behandlungsraum annähernd senkrecht zur Feldrichtung des elektrischen Hochspannungsfeldes, welches durch die Kαndensatorplatten 4, 5 erzeugt wird, verläuft.6 to 9, the treatment room 1 is formed by a one-piece vessel 29 made of insulating material, in which the inlet and outlet openings 2, 3 are provided, and the condensate plates 4, 5 are embedded in the insulating walls thereof are. The coil 30 provided to form the magnetic field passing through the treatment room 1 is arranged in the region of the web 28, which forms a U-shaped flow path from the treatment room 1, and is placed in such a way that the field direction of the magnetic field of this coil in the treatment room is approximately perpendicular to the field direction of the electrical high-voltage field, which is generated by the Kαndensatorplatten 4, 5, runs.

Die Kondensatorplatten 4, 5 sind über Verbindungsleitungen 31 an den Ausgang 10 der Gleichspannungs-Hochspannungsquelle 8 angeschlossen; die am Ausgang 10 der Hochspannungsquelle 8 wirksame Kapazität ist durch einen Kondensator 14 dargestellt. Die Spule 30 bildet einen von der Kondensatαrplatte 4 zur Kondensatorplatte 5 führenden Stromkreis, in den ein als Funkenstrecke 16 ausgebildetes Schalterelement eingefügt ist. Die Durchschlagspannung der Funkeastrerke 16 ist mittels einer Schraube 17 einstellbar. Die Spule 30 bildet zusammen mit den Kondensatorplatten 4, 5 bzw. der wirksamen Kapazität 20 derselben und der Kapazität 14 der Hochspannungsquelle 8 einen hochfrequenten Schwingkreis.The capacitor plates 4, 5 are connected via connecting lines 31 to the output 10 of the DC high-voltage source 8; the capacitance effective at the output 10 of the high-voltage source 8 is represented by a capacitor 14. The coil 30 forms a circuit leading from the capacitor plate 4 to the capacitor plate 5, into which a switch element designed as a spark gap 16 is inserted. The breakdown voltage of the radio amplifier 16 can be adjusted by means of a screw 17. The coil 30 forms, together with the capacitor plates 4, 5 or the effective capacitance 20 thereof and the capacitance 14 of the high-voltage source 8, a high-frequency resonant circuit.

Bei Speisung der Hochspannungsquelle 8 über die Klemmen 9 baut sich am Ausgang der Hochspannungsquelle 8 eine hohe Gleichspannung auf, welche auch an den Kondensatorplatten 4,5 liegt. Erreicht der Wert dieser Hochspannung die Durchschlagspannung der Funkenstrecke 16, kommt es zu einer schlagartigen Entladung über die Spule 30 und gleichzeitig damit zu einer Schwingung, wodurch kurzzeitig dem elektrischen Hochspannungsfeld, welches zwischen den Kondensatorplatten 4, 5 wirksam ist, und durch den langsamen Spannungsaufbau am Ausgang der Hochspannungsquelle eine langsam veränderliche Komponente besitzt, nun eine hochfrequente Komponente durch die von der Entladung stammenden Schwingung erteilt wird. Gleichzeitig wird durch den die Spule 30 durchfließenden Strom während eines kurzen Zeitabschnittes ein starkes Magnetfeld erzeugt, das auf die zu behandelnde Flüssigkeit im Behandlungsraum 1 einwirkt.When the high-voltage source 8 is supplied via the terminals 9, a high DC voltage builds up at the output of the high-voltage source 8, which is also present on the capacitor plates 4, 5. If the value of this high voltage reaches the breakdown voltage of the spark gap 16, there is an abrupt discharge via the coil 30 and at the same time an oscillation, as a result of which the electrical high-voltage field, which is active between the capacitor plates 4, 5, and due to the slow voltage build-up at the output of the high-voltage source, now has a slowly changing component high-frequency component is given by the vibration originating from the discharge. At the same time, the current flowing through the coil 30 generates a strong magnetic field for a short period of time, which acts on the liquid to be treated in the treatment room 1.

Die erfindungsgemäße Vorrichtung kann mit sehr geringem Energieeinsatz betrieben werden. So kann z.B. bei Ausf ührungsfarmen, wie sie in der Zeichnung dargestellt sind, und bei denen das den Behandlungsraum bildende Gefäß einen Durchmesser von ca. 80 mm hat, mit einem Energieverbrauch von ca. 5 W das Auslangen gefunden werden. The device according to the invention can be operated with very little energy. For example, in execution farms, as shown in the drawing, and in which the vessel forming the treatment room has a diameter of approx. 80 mm, energy consumption of approx. 5 W is sufficient.
