AI Technical Summary
Technical Problem
The discharge region width of existing plasma tubes is difficult to control, resulting in low discharge efficiency and high energy consumption.
Method used
A fluid channel with both ends sealed is formed inside the plasma tube. The fluid channel is also the discharge area formed by the positive electrode and the negative electrode. An insulating tube and a gasket are set between the outer electrode tube and the inner electrode tube to form a closed gas fluid channel. An insulating end is set between the outer electrode tube and the inner electrode tube to achieve a coaxial and fixed discharge area.
Benefits of technology
It improves the ionization efficiency of air in the discharge region, generates higher density and more stable plasma, and reduces energy consumption.

Abstract
The application relates to a plasma generating device, belonging to the technical field of plasma. The device comprises multiple plasma generators (11), each of which is provided with a plasma tube (29). The plasma tube (29) comprises an outer electrode tube (21) and an inner electrode tube (24), and the outer electrode tube (21) and the inner electrode tube (24) are connected to two poles of a high-voltage power supply. The device is characterized in that: the positive electrode tube and the negative electrode tube are sleeved to form a tubular discharge area, the discharge area is closed at both ends to form a gas fluid channel (28), and the outer electrode tube (21) is provided with a flow port (20) for the gas to enter and flow out of the fluid channel (28). In the plasma generating device, the fluid channel is formed in the plasma tube and is closed at both ends, and the fluid channel is the discharge area formed by the positive electrode and the negative electrode, so that the ionization efficiency of air passing through the discharge area can be greatly improved, the density of generated plasma is higher, and the plasma is more stable.
