Liquid medium non-transfer arc plasma gun

Abstract

The invention relates to a liquid medium non-transferred arc plasma gun, which mainly includes: a cathode tube arranged in the rear gun body of the plasma gun, and the rear end of the cathode tube is provided with a plurality of liquid medium through holes, which are arranged in the plasma gun. The anode tube in the front gun body of the plasma gun is fixed on the insulator between the front gun body and the rear gun body, the insulator is provided with a plurality of communication holes, and a ceramic ring fixed inside the insulator, Used to constrain the plasma arc generated between the cathode tube and the anode tube, the present invention uses liquid as the medium, only a small amount of liquid can provide enough ion gas, and the volume of the liquid will expand after boiling and evaporating in the cathode tube Thousands of times, it can completely replace the gas medium, and the effect is significantly improved compared with the gas medium. In the process of designing a non-transferred arc plasma gun, there is no need to consider the gas path, which simplifies the structure of the gun body.

Description

technical field [0001] The invention belongs to the field of plasma technology, and in particular relates to a liquid medium non-transferred arc plasma gun. Background technique [0002] The plasma state is the fourth state of matter, and almost 99% of the matter in the universe (excluding the unidentified dark matter) is in the plasma state. The temperature distribution of the plasma ranges from a low temperature of 10 K to an ultra-high temperature of 1 billion K for nuclear fusion plasma, and has a series of unique properties, which make plasma play an important role in the production of nanomaterials, synthesis of new materials, thermal processing, smelting, drilling, It has been widely used in coal chemical industry, waste treatment, material surface treatment, electronics, new energy, military, aerospace and other fields. [0003] In recent decades, the research and development of plasma generators and the development of plasma diagnostic technology have made great pr...
