Internally-hollow cathode double-compression plasma generating device with long service life

Abstract

The invention discloses an internally-hollow cathode double-compression plasma generating device with long service life, comprising a cathode and an anode, wherein the cathode and the anode are distributed on a same centre line at front and back and respectively connected with an anode phase and a cathode phase of a direct current power supply and a high voltage pulse laser; the internally-hollow cathode double-compression plasma generating device also comprises a first electromagnetic coil and a second electromagnetic coil, wherein the first electromagnetic coil surrounds outside the cathode and keeps in an electrifying state when the device works; the second electromagnetic coil surrounds outside the anode and keeps in an electrifying state when the device works; and a second path of carrier wind is introduced in the working process of the device, and a first path of carrier wind can be introduced or closed as required. The internally-hollow cathode double-compression plasma generating device with long service life, provided by the invention, can effectively solve the problem of shorter service life of a plasma generating device in the prior art.

Description

technical field [0001] The invention relates to the field of plasma application, in particular to a long-life inner hollow cathode double-compression plasma generator. Background technique [0002] Plasma generators are mainly used to generate high-power high-temperature plasma. This kind of high-temperature plasma with extremely high energy density can have a core temperature above 4000K. It can be widely used in coal powder ignition and stable combustion in thermal power stations, building materials and cement Kiln pulverized coal combustion, medical waste incineration, high temperature smelting and metal anti-corrosion spraying and other industries. [0003] The existing plasma generator includes a cathode and an anode. The cathode and the anode are distributed on the same center line, and are respectively connected with the positive and negative phases of the DC power supply and the high-voltage pulse exciter. The rear end of the cathode is provided with a carrier wind. ...
