Abstract

A liquid medium plasma discharge generating apparatus includes a main body; a power electrode, provided at one side within the main body, for receiving electric power; a diaphragm member provided within the main body, and consisting of a dielectric defining one or more holes or slits; and a liquid medium charged inside the main body, wherein a ground electrode may be further provided in the main body, opposite the power electrode with the diaphragm member therebetween, whereupon the diaphragm member is arranged contacting the ground electrode.

Claims (28)

1. A liquid medium plasma discharge apparatus, comprising:

a main body filled with a liquid medium;

a power electrode provided at one side in the main body to receive electric power; and

a dielectric diaphragm member provided in the main body,

wherein the dielectric diaphragm member includes a dielectric and has at least one hole or slit configured to generate a plasma discharge channel therein.

2. The liquid medium plasma discharge apparatus according to claim 1 , wherein the dielectric diaphragm member is disposed in contact with the power electrode.

3. The liquid medium plasma discharge apparatus according to claim 2 , wherein a dielectric constant of the dielectric diaphragm member is smaller than a dielectric constant of the liquid medium.

4. The liquid medium plasma discharge apparatus according to claim 2 , wherein a strength of an electric field generated in the hole or slit by the power electrode increases as a dielectric constant of the dielectric diaphragm member decreases.

5. The liquid medium plasma discharge apparatus according to claim 2 , further comprising a ground electrode provided in the main body opposite the power electrode with the dielectric diaphragm member interposed therebetween, wherein the dielectric diaphragm member is disposed in contact with the ground electrode.

6. The liquid medium plasma discharge apparatus according to claim 5 , wherein a dielectric constant of the dielectric diaphragm member is smaller than a dielectric constant of the liquid medium.

7. The liquid medium plasma discharge apparatus according to claim 5 , wherein a strength of an electric field generated in the hole or slit by the power electrode increases as a dielectric constant of the dielectric diaphragm member decreases.

8. The liquid medium plasma discharge apparatus according to claim 1 , wherein the dielectric diaphragm member is disposed at a distance from the power electrode.

9. The liquid medium plasma discharge apparatus according to claim 8 , wherein a dielectric constant of the dielectric diaphragm member is smaller than a dielectric constant of the liquid medium.

10. The liquid medium plasma discharge apparatus according to claim 8 , wherein a strength of an electric field generated in the hole or slit by the power electrode increases as a dielectric constant of the dielectric diaphragm member decreases.

11. The liquid medium plasma discharge apparatus according to claim 8 , further comprising a ground electrode provided in the main body opposite the power electrode with the dielectric diaphragm member interposed therebetween, wherein the dielectric diaphragm member is disposed in contact with the ground electrode.

12. The liquid medium plasma discharge apparatus according to claim 11 , wherein a dielectric constant of the dielectric diaphragm member is smaller than a dielectric constant of the liquid medium.

13. The liquid medium plasma discharge apparatus according to claim 11 , wherein a strength of an electric field generated in the hole or slit by the power electrode increases as a dielectric constant of the dielectric diaphragm member decreases.

14. The liquid medium plasma discharge apparatus according to claim 1 , wherein a dielectric constant of the dielectric diaphragm member is smaller than a dielectric constant of the liquid medium.

15. The liquid medium plasma discharge apparatus according to claim 1 , wherein a strength of an electric field generated in the hole or slit by the power electrode increases as a dielectric constant of the dielectric diaphragm member decreases.

16. The liquid medium plasma discharge apparatus according to claim 1 , further comprising a power supply device configured to supply to the power electrode a voltage sufficient to cause plasma discharge in the liquid medium.

17. The liquid medium plasma discharge apparatus according to claim 1 , further comprising a ground electrode provided in the main body opposite the power electrode with the dielectric diaphragm member interposed therebetween, wherein the dielectric diaphragm member is disposed in contact with the ground electrode.

18. A liquid medium plasma discharge apparatus, comprising:

a main body filled with a liquid medium;

a power electrode provided at one side within the main body to receive electric power;

a dielectric diaphragm member provided in the main body, the dielectric diaphragm member being composed of a dielectric having at least one hole or slit; and

a ground electrode provided in the main body opposite the power electrode with the diaphragm member interposed therebetween, wherein the diaphragm member is disposed in contact with the ground electrode.
