Thereby, the utility model has the advantages of large ozone generating capacity and high conversion efficiency, and simultaneously, has the advantages of reliable equipment, simple process, convenient maintenance, and long service life.

Description

High efficient cryogenic plasma formula ozonizer

The utility model relates to a kind of low-temperature plasma formula ozonizer, is particularly useful for environmental pollution serious heavy dose of air disinfection and purification Chinese medicine, grain depot, food preservation unit and water purification equipment.

The most representative ozonizer has two big classes at present: a class is a tubular structure, and inside and outside distribution one discharge electrode of insulation tube forms creeping discharge under high alternating voltage effect, makes the airborne partial oxygen cyclostrophic that attaches tube outer surface turn to ozone.Its shortcoming is that transformation efficiency is low, and when power drives power was quite big, insulation tube surfaces externally and internally temperature raise rapidly, the ozone generating capacity is sharply descended, therefore must be aided with heavy cooling apparatus, and useful life is very short, only hundreds of hour (make businessman and all declare several thousand hours); Another kind of is the radio ceramics creeping discharge ozonizer of the Japan scientist invention eighties, at pottery or two depositions of glass medium noble metal grizzly bar shape electrode, under action of alternative electric field, form creeping discharge, produce ozone, initial ozone generating capacity is than last class piped height, but in the work beginning several seconds, ceramic plate generate heat rapidly and seriously hot (can reach more than 100 ℃), decompose maximum temperature value considerably beyond ozone, so the ozone that produces is dissolved along face high temperature again immediately, if do not take powerful cooling provision, to switch on after several minutes, it is zero that the ozone of generation almost sharply falls sharply.Again because ceramic plate is seriously hot, and the metal electrode of surface deposition also is evaporated fast and narrows down, ruptures, lost efficacy, so the pottery that a slice is known as 3000-6000h often has only several thousand hours along the face ozonizer practical life, even shorter.And because of using noble metal electrode and valuable stupalith, involve great expense, manufacturing process is also complicated, and qualification rate is low.Be only applicable to short time duty and few dosage sterilizing and purifying occasion.

In view of this, the purpose of this utility model provides a kind of high efficient cryogenic plasma formula ozonizer, and it is to adopt line and sheet separation stable impact corona discharge structure, makes the ozone generating capacity big, efficiency of conversion height, and long service life.

The purpose of this utility model realizes like this: it mainly is made up of interlaced parallel line electrode and plate electrode, and each wire electrode connection negative pole, and plate electrode connects positive pole; Spacing equates between adjacent again line electrode and the plate electrode.

The two ends of described each plate electrode are plugged on respectively on the insulation flat board of both sides, and that insulation is passed at the two ends of described each line electrode respectively is dull and stereotyped and be connected on the insulation flat board with screw rod.

Described respectively the insulation is provided with insulation rod and connects in aggregates between the flat board.

Because adopt such scheme: the ozone generating capacity is big, efficiency of conversion is high, equipment is reliable simultaneously, and technology is simple, keeps conveniently, and increases the service life greatly.

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1, present embodiment is by line electrode 6 and plate electrode 7 and corresponding insulation

flat board

2,11 and 4,9, and compositions such as the insulation rod between each line electrode 6 and each

plate electrode

73,5 and 10, wherein line electrode 6 and plate electrode 7 all adopt valency metallic substance inequality, to produce best corona discharge effect.

The line electrode group structure of present embodiment is shown in Figure 2, is made up of some parallel layers line electrodes, and every layer is arranged in parallel into same plane layer by some wire electrode 6 in parallel, and all line electrodes 6 are connected in parallel as negative pole 12.Line electrode 6 is fixed on the insulation flat board 2,11 of Fig. 4 (a) and Fig. 4 (b), and every line electrode 6 is fixed in the insulation dull and stereotyped 2,11 on the corresponding adjusting screw(rod) 1, and this screw rod 1 is used for regulating the tightness of line electrode 6 dull and stereotyped 2,11 of parallel two insulation.

Present embodiment as shown in Figure 3, is made up of some parallel layers plate electrodes 7, and every layer of plate electrode 7 width and every layer line electrode 6 are arranged width and adapted, and all plate electrodes 7 are connected in parallel as anodal 8.Plate electrode 7 is fixed on the insulation flat board 4,9 of Fig. 5 (a) and Fig. 5 (b), and equidistant parallel notch is offered in dull and stereotyped 4,9 inboards of this insulation, cleans for plate electrode 7 convenient insertion installations and convenient extraction the out.The through hole of offering in the middle of the parallel notch conveniently is inserted in and provides line electrode 6 discharge insulating spaces for line electrode 6.The fixed insulation flat board 4,9 of line electrode 6, plate electrode 7 all adopts the insulating material of the high pressure resistant high frequency of macromolecular structure.

Line electrode 6 parallel being inserted between the plate electrode 7 connect into a rigid body to the fixing insulation

flat board

2,4,9,11 of two arrays of electrodes securely with

insulation rod

3,5,10, and guarantee that adjacent line and plate electrode are parallel to each other and equidistant.

The plate electrode of the line of present embodiment producer and plate electrode body is received the positive pole of driving power high pressure output, and line electrode is received the negative pole of driving power high pressure output.

The advantage of the utility model generator is because positive and negative sparking electrode adopts respectively the not metal of identical ionization potential Material, and negative discharge electrode employing linear structure, positive discharge electrode adopts plate-like structure, can improve to large extent corona Discharging efficiency improve the ozone generating capacity, and output is steady, and be that flaky pottery is along the number of face ozone generator service life Ten times, hundreds of times. Simple in structure, technology is made easily, and is cheap, very easily universal. Energy consumption is low, makes on an equal basis Under condition, power-dissipation-reduced about 30%.
