Abstract

A plasma spark discharge reactor for treating water. The plasma spark discharge reactor comprises a HV electrode with a head and ground electrode that surrounds at least a portion of the HV electrode. A passage for gas may pass through the reactor to a location proximate to the head to provide controlled formation of gas bubbles in order to facilitate the plasma spark discharge in a liquid environment.

First claim

What is claimed is:

1 . A plasma spark discharge reactor comprising:
a HV electrode having a head; a ground electrode surrounding at least a portion of the HV electrode; and a gas passage extending to an outlet at a location proximate to the head of the HV electrode.

2 . The plasma spark discharge reactor of claim 1 , wherein the HV electrode and the ground electrode are co-axial.

3 . The plasma spark discharge reactor of claim 1 , wherein the gas passage extends longitudinally through the HV electrode.

4 . The plasma spark discharge reactor of claim 1 , wherein the gas passage extends longitudinally in an area between the ground electrode and the HV electrode.

5 . The plasma spark discharge reactor of claim 1 , further comprising an insulator.

6 . The plasma spark discharge reactor of claim 5 , wherein the gas passage extends longitudinally through the insulator.

7 . The plasma spark discharge reactor of claim 1 , wherein the reactor further comprises a side passage fluidly connected to the gas passage and the side passage extends at an angle from the gas passage to an outlet proximate to the head of the HV electrode.

8 . The plasma spark discharge reactor of claim 1 , wherein the reactor further comprises a plurality of side passages fluidly connected to the gas passage and the side passages each extend at an angle from the gas passage to an outlet proximate to the head of the HV electrode.

9 . The plasma spark discharge reactor of claim 1 , wherein the HV electrode and ground electrode are oriented substantially vertically.

10 . The plasma spark discharge reactor of claim 1 , wherein the head of the HV electrode is rounded.

11 . The plasma spark discharge reactor of claim 1 , wherein the HV electrode and ground electrode partially enclose a space between the HV electrode and ground electrode in a manner which retains gas in the space as a result of buoyancy.

12 . A water treatment system comprising,
a chamber for holding produced water; and a plasma spark discharge reactor comprising:
a HV electrode with a head;
a ground electrode surrounding at least a portion of the HV electrode; and
a gas passage extending to an outlet a location proximate to the head of the HV electrode.

13 . The water treatment system of claim 12 , wherein the gas passage extends longitudinally through the HV electrode.

14 . The plasma spark discharge reactor of claim 12 , wherein the gas passage extends longitudinally in an area between the ground electrode and the HV electrode.

15 . The plasma spark discharge reactor of claim 12 , further comprising an insulator.

16 . The plasma spark discharge reactor of claim 15 , wherein the gas passage extends longitudinally through the insulator.

17 . The water treatment system of claim 12 , wherein the plasma spark discharge reactor is oriented substantially vertically.

18 . The water treatment system of claim 12 , wherein the plasma spark discharge reactor is oriented substantially horizontally.

19 . The water treatment system of claim 12 , comprising a plurality of plasma spark discharge reactors.

20 . A plasma spark discharge reactor as claimed in claim 12 , wherein the head is rounded.
