Problems solved by technology

[0002] The use of plasma pyrolysis of coal to produce acetylene is a short-flow, high-efficiency acetylene production method. Due to the characteristics of high temperature and high enthalpy change of the plasma, and the small volume of the plasma pyrolysis coal powder to produce acetylene reactor, it is easy to produce acetylene. cause the reactor wall to be burned
Moreover, the temperature in the reaction zone is not easy to control, resulting in uneven reaction of pulverized coal and low utilization efficiency of pulverized coal
[0003] Plasma gun is a common device for generating plasma, but there are many problems in existing plasma guns, such as uneven distribution of electric field intensity in plasma gun, low power, low plasma formation efficiency, and short service life

Abstract

The invention provides a plasma coal acetylene plasma gun which comprises a hemispherical high-voltage electrode set to be a two-layer structure, a magnetron coil assembly, a truncated cone-shaped low-voltage electrode set to be a two-layer structure, and an electrode isolation assembly set to be a two-layer structure. The electrode isolation assembly is used for connecting the hemispherical high-voltage electrode and the truncated cone-shaped low-voltage electrode, and the electrical insulation between the high-voltage electrode and the low-voltage electrode is ensured. After the high-voltageelectrode, the low-voltage electrode and the electrode isolation assembly are connected, two-layer structures are in communication, and cooling water flow in the structures to carry out temperature control on the plasma gun. The plasma gun disclosed by the invention has the advantages of a simple and reasonable structure, high strength, convenient control, uniform electric field intensity distribution, high plasma formation efficiency and a long service life.

Description

technical field [0001] The invention belongs to the field of plasma technology, and in particular relates to a plasma coal-made acetylene plasma gun. Background technique [0002] The use of plasma pyrolysis of coal to produce acetylene is a short-flow, high-efficiency acetylene production method. Due to the characteristics of high temperature and high enthalpy change of the plasma, and the small volume of the plasma pyrolysis coal powder to produce acetylene reactor, it is easy to produce acetylene. Causes the reactor wall to be burnt. Moreover, the temperature in the reaction zone is not easy to control, resulting in uneven reaction of pulverized coal and low utilization efficiency of pulverized coal. [0003] Plasma gun is a common device for generating plasma, but there are many problems in existing plasma guns, such as uneven distribution of electric field intensity in plasma gun, low power, low efficiency of plasma formation, and short service life.
