Technical Field
The utility model belongs to the technical field of the environmental protection technique and specifically relates to a discharge ion needle is related to.
Background
The plasma technology is a high and new technology with extremely strong potential advantages in the field of environmental pollution treatment, and the principle of treating pollutants is as follows: under the action of an external electric field, a large amount of energy-carrying electrons generated by medium discharge bombard pollutant molecules, so that the pollutant molecules are ionized, dissociated and excited, and then a series of complex physical and chemical reactions are initiated, so that complex macromolecular pollutants are converted into simple micromolecular safe substances, or toxic and harmful substances are converted into non-toxic and harmless or low-toxic and low-harmful substances, and the pollutants are degraded and removed. Since the average energy of electrons generated after ionization is 10eV, chemical reactions which are generally difficult to realize or have a very slow speed can be realized by properly controlling the reaction conditions. Therefore, plasma dust removal technology is gaining more and more attention.
In the prior art, for a discharge rod (also commonly referred to as an electron discharge needle) for connecting a negative electrode of a power supply in plasma equipment, a cylindrical or rectangular metal rod is generally adopted as a main bearing structure, and then a cylindrical small-diameter metal rod is welded on the metal rod as a discharge structure. The existing discharge rod needs a worker to have more skilled operation skill to ensure the levelness of the small-diameter metal rod on the same plane during manufacturing, and in addition, for plasma equipment with different sizes, the position of the small-diameter metal rod in the axial direction of the metal rod cannot be adjusted, so that the discharge rod has no universality, and for the plasma equipment with a specific size, the discharge rod can only be special. Resulting in high production efficiency and high use cost of the parts.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Fig. 1 is a schematic diagram showing a structural principle of an electron discharge needle according to an embodiment of the present invention; FIG. 2 is a schematic diagram showing the structure of the discharge needle of FIG. 1; fig. 3 is a schematic perspective view of the round bar of fig. 1. Referring to fig. 1-3, the utility model provides a discharge ion needle, it includes a round bar 1 and a plurality of discharge needle 2 of interconnect, discharge needle 2 including be used for with the annular base 21 that round bar 1 cup jointed and at least three needle bodies 22 of annular base 21 outside circumference equipartition, needle body 22 tip is provided with the needle point 23 that the diameter is 2-3mm, annular base 21 swing joint has a locating pin 211, round bar 1 outer wall is provided with a plurality of parallels and axis vertically annular location mounting groove 11
The annular base 21 and the needle body 22 can be made of general corrosion-resistant metal materials (such as 205 stainless steel), the needle point 23 can be made of platinum alloy materials, and the needle point 23 is directly set to be 2-3mm, so that the discharge effect can be guaranteed on one hand, and the material cost can be reduced on the other hand.
The axial length ratio of the needle tip 23 to the needle body 22 may be 1: 50-1: 100, that is, when the needle body 22 has a length of 50 to 100mm, the length of the needle tip 23 can be kept set at 1 mm.
Annular base 21 can ensure the circumference equipartition of needle point 23, will discharge needle 2 cup joints when the round bar 1 is last, can be earlier taken out locating pin 211, avoid locating pin 211 is in the inboard influence of annular base 21 discharge needle 2's removal, work as discharge needle 2 removes extremely during location mounting groove 11 position, insert locating pin 211 makes locating pin 211 inserts location mounting groove 11, just so can fix discharge needle 2 is in position on the round bar 1.
The positioning installation grooves 11 can be uniformly distributed at intervals of 10-20 mm.
When the horizontal rotation angle of the discharge needle 2 needs to be adjusted in a rotating mode, the discharge needle 2 can horizontally rotate along the positioning installation groove 11 only by pulling the positioning pin 211 out and keeping the positioning pin 211 in contact with the positioning installation groove 11. After the discharge needles 2 are rotated to the right position, the positioning pins 211 are inserted tightly, so that the two adjacent discharge needles 2 having the same axial distance have the same circumferential deflection angle (for example, 30 °) in the horizontal direction, and the discharge needles 2 are distributed more uniformly. The formed ionization field is more uniform.
In the use of later stage, need adjust during the position of discharge needle 2, only need extract locating pin 211, adjustment that can convenient and fast discharge needle 2 to difference positioning mounting groove 11 to convenient adjustment discharge needle 2's position just also can make the utility model provides a discharge ion needle can be applicable to different plasma equipment.
The utility model provides an electron discharge needle, simple structure, the equipment location is convenient, and can adjust the position relation between the adjacent discharge needle as required to can possess the commonality, make use cost reduce by a wide margin.
