Plasma tube and plasma generator

Abstract

A plasma tube and plasma generator belong to the field of plasma technology. It includes a positive electrode tube and a negative electrode tube, which are respectively connected to the two poles of a high-voltage power supply. A discharge region is formed between the positive and negative electrode tubes. The key feature is that the positive and negative electrode tubes are inner and outer sleeved to form a tubular discharge region. The two ends of the discharge region are closed to form a gas fluid channel. Openings for gas entry and exit from the fluid channel are formed on the outer surface of the sleeved positive and negative electrode tubes. In the plasma tube of this application, a closed-end fluid channel is formed between the positive and negative electrode tubes. This fluid channel simultaneously serves as the discharge region formed by the positive and negative electrodes. Therefore, the width of the discharge region formed between the positive and negative electrode tubes is small, which can greatly improve the ionization efficiency of air passing through the discharge region, resulting in a higher and more stable plasma density, and reducing energy consumption.
