Problems solved by technology

[0005] On the other hand, most of the existing plasma generators on the market use a subsonic flow state, and the outlet is a simple circular shape. The thermal plasma jet cannot form a supersonic flow state, and is easily affected by the working pressure of the external environment.
Especially in applications where the external environm...

Abstract

The invention discloses a plasma generator. The plasma generator comprises a first carbon electrode, a first metal electrode and a compensation feeding device; the first metal electrode is provided with a cavity, and the cavity comprises a first end constructed as an outlet of plasmas and a second end opposite to the first end, wherein the first carbon electrode extends into the cavity through thesecond end; and the compensation feeding device is fixedly connected with the first carbon electrode and drives the first carbon electrode to move towards the outlet, wherein the inner surface of theoutlet is constructed to be gradually far away from the center line of the cavity in the direction from the second end to the first end or constructed to be gradually close to the center line firstlyand then far away from the center line in the direction from the second end to the first end.

Description

technical field [0001] The present invention relates to the technical field of plasma generators, in particular to a plasma generator. Background technique [0002] Arc plasma generators are also called arc plasma torches, or plasma spray guns, and sometimes arc heaters. The arc plasma generator is a discharge device capable of generating directional "low temperature" (about 2000 Kelvin to 20000 Kelvin) plasma jets. widely used in the field. The main technical indicators of arc plasma generators used in industry are power, efficiency and continuous service life. [0003] The arc plasma generator is mainly composed of two poles consisting of a cathode and an anode (the anode is replaced by a workpiece), a discharge chamber and a plasma working gas supply system. The cathode and anode of commonly used plasma generators are mostly made of metal materials. Due to the cathode loss of plasma generators, refractory metal materials or high thermal conductivity metal materials are...
