500 KW magnetic stability non-transferred arc plasma generator

Abstract

The invention provides a 500 KW magnetic stability non-transferred arc plasma generator which is provided with a cathode with a cavity, an insulating cylinder, a gap, a first anode, an adjustable insulation seat, a main gas ring, a second anode, a seal, a third anode, a blasting opening and a fourth anode in a spray direction sequentially. Center holes and cooling water ways are formed in all anodes. Auxiliary gas enters the cathode cavity through an auxiliary gas hole in the center of the top of the cathode cavity; main gas is screwed into the top of the second anode through the main gas ring; protection gas is screwed into the top of the fourth anode through the blasting opening; magnetic stability coils are arranged on the outside of the cathode and the and fourth anode. The negative pole of a direct current power supply is connected with the cathode; four anodes on which transfer arc switches are mounted are connected to the positive pole of the direct current power supply. The arc voltage is improved by a four-anode structure, and the power is as high as 500KW. The auxiliary gas, the main gas and the protection gas guarantee dynamic contact of gas and electrodes. The magnetic stability coils enable the arc to be stable and uniform. The service life of the cathode can be prolonged by the aid of the cathode cavity structure. The 500 KW magnetic stability non-transferred arc plasma generator can be used for rubbish and industrial waste virus-free and energy regeneration treatment, radioactive waste disposal, new nano material preparation and the like.

Description

technical field [0001] The invention relates to a high-power (above 100KW) plasma generator, which belongs to ion generation and spark gap category (H01T). Background technique [0002] Plasma is a state of matter composed of many charged particles, the sum of which is approximately electrically neutral, and widely exists in universe It is also the most abundant form of matter in the universe, and is often regarded as the fourth state of matter. As the temperature rises, the substance has a three-state transformation process of solid, liquid, and gas. When the temperature of the gaseous substance rises to several thousand degrees, the gas molecules are ionized, so that the substance becomes a composition of positive ions and electrons that move freely and interact. The mixture, the plasma. Its temperature distribution ranges from 100K low-temperature plasma to ultra-high temperature nuclear mutation plasma of 10 8 ~10 9 K (1 to 1 billion degrees Celsius). The particles ...
