Abstract

The utility model relates to a discharge electrode of a plasma generator. The discharge electrode is in a knife edge and long strip shape, two sides of the electrode are in sharp knife edge shapes, circles with gaps are arranged at two ends of the long strip, and the electrode is made of titanium alloy or stainless steel sheets. The thickness of the electrode ranges from 0.1 mm to 0.5 mm and the width of the electrode ranges from 3 mm to 20 mm. The preferred thickness is 0.3 mm and the preferred width is 12 mm. Multiple layers of the discharge electrode are disposed at intervals vertically, the vertical interval ranges from 20 mm to 80 mm with the preference of 30 mm, and the horizontal interval ranges from 20 mm to 100 mm with the preference of 30 mm. The whole knife edge portions of the discharge electrode can discharge so that the discharge area is multiple times larger than that of a needlepoint-shaped discharge electrode and tooth-point-shaped discharge electrode, and the service life is multiple times longer than that of a wire-shaped electrode. The discharge electrode of the plasma generator is high in plasma density generated in the air, long in service life and simple in structure.

Description

A kind of discharge electrode of plasma generator

Technical field

The utility model relates to plasma producing apparatus, specifically refers to a kind of discharge electrode of plasma generator.

Background technology

The operation principle of plasma generator is exactly the positive pole of discharge and placed by the negative pole spaced and parallel of electricity, and anodal and negative pole is together in series with circuit respectively, and insulation each other.Plasma generator is when connecting high-tension electricity, anodal discharge position such as needle point, crown punctures air to the negative pole emitting electrons, in air, produce plasma, and allow circulating air pass through plasma generator by forced ventilation, make the high concentration plasma spreads to indoor, the effect that reach disinfection, purifies air.In permanent discharge process, metal structure anodal and negative pole all can have ablation in various degree, the less place of particularly anodal area, the but position of discharging and concentrating just, for example needle point or crown position are at first burnt short and are influenced discharge effect, and of a specified duration then blows easily.And needle point or crown arrange that at interval the position of itself discharging is sparse, and the plasma density of generation is just little.Plasma reactor in the market mainly adopts thread discharge electrode, dentation discharge electrode or tip-like discharge electrode structure.The defective of thread discharge electrode is that requirement line footpath is thinner, and generally between ￠ 0.1mm～0.25mm, because the ablation effect of permanent electrion, fracture or short circuit can appear in the discharge electrode wire, gently then quit work, and is heavy then also can cause fire.Wire detailed rules and regulations more is short more useful life, and the general life-span of silk of ￠ 0.15mm is at 0.5 year～2 years, the thick more ozone that then is easy to generate of wire.

Though the dentation discharge electrode is relative more longer than wire electrode useful life with the tip-like discharge electrode, because there is the gap in crown, the position of discharge is more sparse, so it is not high to produce the concentration of plasma.

In view of above-mentioned defective, the inventor furthers investigate, and this case takes place thus.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of discharge electrode of plasma generator is provided, and makes the whole discharge in both sides of discharge electrode, and the multiplication of discharge part figure place is big, can produce the high concentration plasma in uniform high-efficiency ground, and useful life is longer.

To achieve these goals, the technical solution of the utility model is as follows: a kind of discharge electrode of plasma generator, adopt resistance to oxidation alloy material thin slice to make, long strip type electrode both sides are sharp edge of a knife shape, the discharge electrode two ends are provided with notched annulus, it is in order to allow annulus increase a little elasticity, to be inserted in fixed lever when being convenient to assemble, can blocking and go up in position that breach is set.Thick 0.1mm～the 0.5mm of discharge electrode thin slice, wide 3mm～20mm.The preferred material of discharge electrode be in titanium alloy, the stainless steel any one; Discharge electrode thin slice preferred thickness is 0.3mm, and preferable width is 12mm.

A kind of discharge electrode of plasma generator is counted interlayer up and down every placement, and the vertical direction spacing distance is 20mm～80mm, is preferably 30mm; The horizontal direction array pitch is 20mm～100mm, is preferably 30mm.　

Edge of a knife shape long strip type discharge electrode of the present invention, the discharge of edge of a knife position, both sides entire body, the machining area several times growth than tip-like, tooth tip shape prolongs than thread discharge electrode several times in useful life again.If in use for some time, concentrate to hand over manufactory with special equipment the both sides edge of a knife once more grinding sharp after, can reuse for a long time again.　

The invention has the beneficial effects as follows: the plasma density height that in air, produces, long service life, simple in structure.

Description of reference numerals:

1 positive plate, 11 edges of a knife, 12 installing rings, 13 breach, 2 fixed levers, 3 negative plates.

Embodiment

Below by drawings and Examples the utility model is further elaborated.

To shown in Figure 2, the positive plate 1 of plasma generator adopts the manufacturing of titanium alloy thin slice as Fig. 1, and long 260 millimeters, thick 0.3mm, wide 12mm.Three interlayers are every placement about in the of 1 for positive plate, and two ends installing ring 12 is fixed on the metal fixed lever 2.Positive plate 1 bilateral symmetry is negative plate 3 on end, and the array spacings distance of adjacent cathode sheet 3 is 30 millimeters.As shown in Figure 1, have 6 arrays and be fixed in the rectangular frame of insulation, with following sky, be convenient to air and circulate up and down above the rectangular frame.All fixed lever 2 usefulness circuit connect, and all negative plate 3 usefulness circuit connect and ground connection, and the complete machine electromagnetic compatible performance is good after the ground connection.Article two, circuit is received power input respectively, and insulation each other.The transformer that carries by plasma generator is imported the direct current of 5 KV～12 KV to both positive and negative polarity, and the unlatching blower fan makes air circulation, 30 square metres rooms are used plasma generator work 60 minutes, just can reach the purpose of disinfection, smoke abatement and dust control, use more to ward, operating room, use also can be played the air cleaning effect to home dwelling, and people and pet needn't leave indoor during use.
