Abstract

The invention relates to a plasma generating device, which aims at carrying out different combinations according to different requirements to generate plasmas with different areas and different shapes, and generating plasmas on one plane or multiple planes, such as cylindrical or conical plasmas. The plasma generating device comprises a power supply, high-voltage electrodes, ground electrodes and dielectric tubes; the high-voltage electrodes and the ground electrodes which are arranged in the dielectric tubes are respectively adjacent, that is to say, the high-voltage electrodes and the ground electrodes are bound to be respectively placed in two adjacent dielectric tubes; and the plasmas can be generated in clearances between the outer walls of the dielectric tubes and the dielectric tubes. The plasmas of which the temperature approaches to room temperature can be generated by using different power supply parameters, thus the application at normal temperature and normal pressure is realized. According to the device, the plasmas of which the temperature approaches to room temperature can be generated according to different shapes in a large area and the dielectric tubes generating the plasmas in the device can be made of bendable material, thus the available range of the device is greatly widened.

Description

technical field [0001] The invention relates to a plasma generating device, in particular to a plasma generating device which can be combined according to different requirements to generate plasma with different areas and shapes. Background technique [0002] Plasma is an ionized gas-like substance composed of atoms deprived of some electrons and positive and negative electrons generated after the atoms are ionized. It is called the fourth state of matter except solid, liquid, and gas. Plasma can be divided into high-temperature plasma and low-temperature plasma according to temperature, among which low-temperature plasma is the most widely used type of plasma, which is widely used in materials, electronics and other fields. There are mainly four types of devices for generating low-temperature plasma, namely AC low-temperature plasma generator, radio-frequency low-temperature plasma generator, microwave low-temperature plasma generator, and DC pulse plasma generator.
