Description

Discharge electrode for low-temperature plasma generating device

Technical Field

The utility model relates to a discharge electrode for low temperature plasma generating device.

Background

In recent years, low-temperature plasma technology has attracted more and more attention, and the high-efficiency and broad-spectrum sterilization effect of low-temperature plasma has been public knowledge. The plasma is referred to as a fourth species existing form other than solid, liquid and gas, and is a species existing form composed of electrons, ions, radicals and neutral particles, which remains electrically neutral as a whole. The plasma generated by discharging gas in a high-voltage electric field, wherein the temperature of heavy particles is very low, and the whole system is in a normal temperature state, is called as low-temperature plasma. The low-temperature plasma acts on the surface of a human body to initiate a series of complex physical and chemical reactions, so that microorganisms such as bacteria, viruses and the like on the surface of the human body can lose activity, and a series of problems caused by infection are avoided on the surface of the human body.

Corona discharge is a reliable and economic method for generating low-temperature (non-equilibrium state) plasma under normal pressure, and is widely applied to the fields of air purification, environmental sterilization and the like.

The discharge electrode of the low-temperature plasma generating device is usually made of a single wire, and the end part of the single wire is a circular plane, so that the discharge point of the discharge electrode of the single wire is only one circle on the edge of the circular plane at the end part of the single wire. More discharge points can be added and more plasma can be generated.
