Background technique
Plasma technique is a kind of one in the environmental pollution treatment field new and high technology with extremely strong potential advantages,
Its principle for handling pollutant are as follows: under the action of extra electric field, what medium discharge generated largely takes energy electron bombardment pollutant
Molecule makes its ionization, dissociation and excitation, has then just caused physics, the chemical reaction of a series of complex, has kept complicated macromolecular dirty
Dye object is changed into simple small molecule safe material, or the substance for making poisonous and harmful substance be transformed into nontoxic or less toxic low evil,
To enable pollutant degradation removal.Because the averaged electron energy generated after its ionization is in 10ev, suitable control reaction condition
The chemical reaction that may be implemented to be difficult to realize under normal circumstances or speed is very slow becomes very quickly.Therefore, plasma dedusting skill
Art is increasingly paid attention to.
In prior art, for, for connecing the discharge lever (electric discharge device) of power cathode, leading in plasma apparatus
Frequently with column or rectangular metal stick as main force support structure, the conduct of cylindricality minor diameter metallic rod is then welded on metal bar and is put
Electric structure.On the one hand during fabrication existing discharge lever needs worker to have more skilled operation skill that could ensure same flat
The levelness of the minor diameter metallic rod in face, in addition, for various sizes of plasma apparatus, since minor diameter metallic rod is in metal
Mandrel to position be unable to adjust, therefore, discharge lever does not have versatility, for the plasma apparatus of specific dimensions, discharge lever
It can only be dedicated.To cause the production efficiency of component and use cost all higher.
Utility model content

The problem of mentioning.
In order to solve the above technical problems, the utility model proposes a kind of plasma discharge apparatus comprising be connected with each other
A round bar and multiple spray points, the spray point includes annular base for being socketed with the round bar and in the ring
Circumferentially uniformly distributed at least three needle bodys of shape chassis outer side, the needle body end are provided with the needle point that diameter is 2-3mm, the annular
Be provided with a positioning protrusion on the inside of pedestal, the round bar outer wall be provided with axially through with the matched spiral shell of the positioning protrusion
Spin slot.
Preferably, the annular base and the round bar are welded to connect.
Preferably, the annular base is provided with a limit screw in opposite with the positioning protrusion.

Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention
Specific embodiment of the present utility model.Wherein, identical component uses identical label.
The structural principle that the plasma discharge apparatus of a specific embodiment according to the present utility model is shown in Fig. 1 shows
It is intended to；The principle schematic diagram of the spray point of Fig. 1 is shown in Fig. 2；Fig. 3 is the stereochemical structure principle signal of the round bar of Fig. 1
Figure.As shown in figure 1 to 3, the utility model provides a kind of plasma discharge apparatus to ginseng comprising a round bar 1 interconnected
With multiple spray points 2, the spray point 2 includes annular base 21 for being socketed with the round bar 1 and at the annular bottom
Uniformly distributed at least three needle bodys 22 of 21 external circumferentials of seat, 22 end of the needle body is provided with the needle point 23 that diameter is 2-3mm, described
Be provided with a positioning protrusion 211 on the inside of annular base 21,1 outer wall of round bar be provided with axially through with the convex
Play 211 matched helicla flutes 11.
The annular base 21 and the needle body 22 can use general corrosion-resistant metal materials (such as 205 stainless steels)
It is made, the needle point 23 can be made of Platinum alloy material, and the needle point 23 is directly disposed as 2-3mm, so on the one hand can
It ensures discharge effect, on the other hand can reduce material cost.
The axial length ratio of the needle point 23 and the needle body 22 can be 1:50-1:100, that is to say, that when the needle
When 22 length of body is 50-100mm, the length of the needle point 23 can remain set at 1mm.
The annular base 21 can ensure that the circumferential direction of the needle point 23 is uniformly distributed, by the positioning protrusion 211 with it is described
The matching of helicla flute 11 can easily adjust the position of the annular base 21 on the round bar 1, and can ensure that in the axial direction
