Auxiliary plasma jet device

Abstract

The invention discloses an auxiliary plasma jet device. The auxiliary plasma jet device comprises a detection control module, an interval adjuster and ground connection drainage pieces, wherein the detection control module is connected with the output end of a high voltage power supply inside the plasma jet device; an opening is formed in the top surface of the interval adjuster and is positionedat the position of a plasma jet nozzle, through holes and grooves are formed in the bottom surface of the interval adjuster, and a plasma jet flow generated by the plasma jet device flows out throughthe through holes in the bottom surface; the ground connection drainage pieces are embedded in the grooves in the bottom surface of the interval adjuster, and are connected with a common earth pole; the detection control module is used for monitoring the voltage and current states of the plasma jet device in real time and disconnecting the high voltage power supply of the plasma jet device when afault occurs; the interval adjuster is used for controlling the length of the plasma jet flow and fixing the ground connection drainage pieces; and the ground connection drainage pieces are used for guiding and discharging plasma current. According to the auxiliary plasma jet device, the application safety of the plasma jet device can be improved, simultaneously a plasma array is discharged uniformly, and the plasma performance is improved.

Description

technical field [0001] The invention belongs to the field of plasma applications, and more specifically relates to a plasma jet auxiliary device. Background technique [0002] Atmospheric pressure non-equilibrium plasma is a plasma generated under atmospheric pressure, and its electron temperature can be as high as tens of thousands of degrees, while the temperature of ions and neutral particles is much lower than the electron temperature, usually close to room temperature, so the gas temperature during discharge is also close to room temperature . The atmospheric pressure low-temperature plasma jet device can generate plasma jets under atmospheric pressure, without limiting the size of the plasma discharge gap to the object to be processed, and is easy to operate, and the generated gas has low temperature and high activity. Existing plasma jet devices have been able to produce various types of non-thermal equilibrium plasmas at atmospheric pressure. A plasma jet device is ...
