Abstract

A plasma jet device belongs to a plasma generator and settles the problem the unsafe electrode and the likely generation of arc discharging between the electrode and the grounding existing in the prior plasma jet device. The plasma jet device according to the invention comprises a power supply, a working gas source and an electrode. The working gas of the working gas source enters the electrode from the gas input port of the electrode. The electrode is in the shape of empty tube, is provided with a gas input port at one end and is provided with a gas output port at the other end. The electrode is connected with the power supply through a resistor and a capacitor. The plasma jet device according to the invention has the advantages of easy manufacture, easy maintenance, convenient use, low cost and easy carrying. The temperature of the generated plasma jet can be different when resistor with different resistance, capacitor with different capacitance, different driving power supply and different working gas are selected. The human body can touch with the plasma jet safely when the temperature of the plasma jet is approximate to the room temperature. At the same time the plasma jet can be provided with different shapes and can diffuse to different directions simultaneously. The specific application with large scale and large area in normal temperature and normal pressure can be realized.

Description

technical field [0001] The invention belongs to a plasma generating device, in particular to a gas discharge plasma jet device. Background technique [0002] Plasma is usually composed of positive ions, neutral particles and electrons. Generally, plasma can be divided into two types: thermal equilibrium plasma and non-thermal equilibrium plasma. Thermal equilibrium means that all particles in the plasma have the same temperature. [0003] In non-thermal equilibrium plasma, the temperature of electrons can be as high as tens of thousands of degrees, while the temperature of ions and neutral particles is much lower than that of electrons. This "hot cooler" has many advantages, and non-thermal equilibrium plasma can be used as a highly active reactant. Widely used in various fields, such as plasma deposition and coating, etching, surface treatment, chemical purification, biological purification and medical applications. [0004] Under atmospheric pressure, due to the relative...
