Patent ID: 8092750

Claim:
A plasma system for generating a plasma, the plasma system comprising: a first tube having a first inlet, at least one first plasma jet opening, a first end surface and a second end surface, wherein the first inlet is disposed on one of the first end surface and the second end surface, wherein a plasma gas passes through the first inlet and enters the first tube, the at least one first plasma jet opening penetrates the wall of the first tube, and the plasma passes through the at least one first plasma jet opening and is emitted to the outside of the first tube; a first positive electrode having a first positive electrode side surface and a first positive electrode surface, wherein the first positive electrode side surface is connected to the first positive electrode surface, and the first positive electrode side surface only surrounds a first portion of the first tube; and a first negative electrode having a first negative electrode side surface and a first negative electrode surface, wherein the first negative electrode side surface is connected to the first negative electrode surface, the first negative electrode side surface only surrounds a second portion of the first tube, and the first negative electrode surface is separated from the first positive electrode surface by a first predetermined distance; wherein the first positive electrode and the first negative electrode are disposed between the first end surface and the second end surface, at least a portion of the first plasma jet opening is disposed between the first positive and first negative electrode, and the at least one first plasma jet opening is located on a side of the tube opposite to the first and second portions of the tube.
