Description
Technical field
The utility model relates to a kind of arc plasma generator.
Background technology
Arc discharge method is used for many years in each field of national economy, and its main application has the plasma cutting, plasma spraying, plasma welding, plasma superfines, plasma waste incineration, plasma pulverized coal ignition technology or the like.Mainly be to utilize the equipment of arc-plasma and technology fairly simple, concentration of energy, the temperature height, characteristics such as control have easily been waited until application widely industrial.
Arc plasma generator can adopt air as working gas, and this is because air is the most facile source of the gas, and the source of the gas low price.Air is ionized to plasma in electric arc, become high-temperature plasma, and its main component is N
2, O
2, N
+, O
+, NO, NO
+Equimolecular and ion also have electronics.Nitrogen in the plasma reacts the generation nitrogen oxide easily with oxygen in high temperature, increase the pollution to atmosphere.
Therefore, need to adopt a kind of new working gas to overcome the problems referred to above.
The utility model content
The utility model proposes a kind of arc plasma generator, its technical scheme is as follows:
A kind of arc plasma generator, comprise anode and negative electrode, this anode has arc channel, by the discharge generation electric arc between anode and the negative electrode, adopt oxidizing gas especially purity oxygen as working gas, forming plasma, plasma is by arc channel and via the spout ejection of anode to working gas heating for this electric arc.
Preferably, arc plasma generator comprises that one is installed in the air inlet ring between anode and the negative electrode, and working gas is tangentially imported arc channel by this air inlet ring, forms the working gas eddy flow in this arc channel.
Preferably, anode and negative electrode are made by the non-oxidizability material, perhaps, and the surface that contacts with the working gas non-oxidizability material coating of the internal face of the arc channel of anode and negative electrode.
Preferably, described non-oxidizability material is chrome zirconium copper alloy or Kufil.
In the utility model, replace air to be used for plasma generator with oxidizing gas especially purity oxygen as working gas, with the problem that solve to adopt air to exist as the arc plasma generator of working gas, produce following advantage: 1) help burning, improve the pyroreaction ability of arc plasma generator; 2) reduce the discharging of nitrogen oxide, reach the purpose of energy-saving and emission-reduction.
Description of drawings
Describe structure of the present utility model and characteristics in detail below in conjunction with accompanying drawing and preferred embodiment.Wherein,
Fig. 1 illustrates the signal longitudinal sectional view of arc plasma generator of the present utility model;
Fig. 2 illustrates the transverse sectional view of the air inlet ring that is used for the utility model arc plasma generator.
Embodiment
Fig. 1 illustrates vertical schematic sectional view of arc plasma generator of the present utility model.This arc plasma generator comprises anode 1 and negative electrode 3, this anode has arc channel 11, by between anode 1 and negative electrode 3, adding direct current (adopting high-frequency arc strike or contacting ignition arc) discharge generation electric arc, producing plasma, plasma is by arc channel 11 and via spout 12 ejections of anode 1 to working gas heating for electric arc.In the utility model, adopt purity oxygen as working gas X.Anode and cathode material adopt oxidation-resistant material,, perhaps also can stipulate the surface non-oxidizability material coating that contacts with working gas X of the internal face of the arc channel 11 of anode 1 and negative electrode 3 to reduce the scaling loss of anode and cathode.At this, the non-oxidizability material is chrome zirconium copper alloy or Kufil.Working gas X enters from the anode and cathode gap by the 2 tangential rotations of air inlet ring.At this, anode 1 and negative electrode 3 preferably are provided with coaxially.
In the utility model, according to a kind of flexible program, because the arc voltage of pure oxygen is lower than the arc voltage of air, diameter and length by change anode arc passage, arc channel attenuated or elongated, increase the length of electric arc compression degree or increase electric arc, improve the voltage of electric arc, thereby increase the power of generator.
