Technical Field
The utility model belongs to the technical field of the flue gas processing technique and specifically relates to a plasma discharge pole 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 for connecting a negative electrode of a power supply in plasma equipment, a columnar or rectangular metal rod is generally adopted as a main bearing structure, and then a columnar 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.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the present invention is to provide a plasma discharge rod to reduce or avoid the aforementioned problems.
In order to solve the technical problem, the utility model provides a plasma discharge pole, it includes a round bar and a plurality of discharge needle of interconnect, the discharge needle including be used for with the annular base that the round bar cup jointed and the at least three needle bodies of annular base outside circumference equipartition, the needle body tip is provided with the needle point that the diameter is 2-3 mm.
Preferably, the annular base is welded to the round bar.
Preferably, a positioning protrusion is arranged on the inner side of the annular base, and a stop screw is arranged on the annular base opposite to the positioning protrusion.
Preferably, a circumferential deflection angle is arranged between two adjacent discharge needles.
Preferably, the circumferential deflection angle is 30 °.
Preferably, the needle tip is made of platinum alloy.
Preferably, the axial length ratio of the needle tip to the needle body is 1: 50-1: 100.
the utility model provides a plasma discharge pole, 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.
Drawings
The drawings are only intended to illustrate and explain the present invention and do not limit the scope of the invention. Wherein,
fig. 1 is a schematic view showing a structural principle of a plasma discharge rod according to an embodiment of the present invention;
fig. 2 is a schematic view showing the structural principle of the discharge needle of fig. 1.
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 view showing a structural principle of a plasma discharge rod according to an embodiment of the present invention; fig. 2 is a schematic view showing the structural principle of the discharge needle of fig. 1. Referring to fig. 1-2, the utility model provides a plasma discharge pole, 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 be in at least three needle bodies 22 of annular base 21 outside circumference equipartition, the needle body 22 tip is provided with the needle point 23 that the diameter is 2-3 mm.
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.
The annular base 21 can ensure circumferential uniform distribution of the needle points 23, the positions of the circular rods 1 can be conveniently adjusted, the circular rods are fixed by welding after being adjusted in place, and the annular base 21 can also conveniently adjust circumferential deflection angles between adjacent discharge needles 2 (for example, two adjacent discharge needles 2 can deflect 30 degrees in the horizontal direction in the circumferential direction), so that the discharge needles 2 are distributed more uniformly. The formed ionization field is more uniform.
Although the annular base 21 and the circular rod 1 may be fixed by spot welding, the welding method may be troublesome to detach when the position of the discharge needle 2 needs to be adjusted at a later stage, and therefore, a positioning protrusion 211 may be provided inside the annular base 21, and a stop screw 212 may be provided on the annular base 21 opposite to the positioning protrusion 211. Accessible is screwed up like this set screw 212, cooperates the location arch 211 is fixed annular base 21's position, like this, in the later stage use, need adjust during the position of discharge needle 2, only need loosen set screw 211, adjustment that can convenient and fast the position of discharge needle 2, thereby can make the utility model provides a plasma discharge pole can be applicable to different plasma equipment.
The utility model provides a plasma discharge pole, 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.
