Abstract

The utility model relates to a plasma technology dedicated device-a ceramic capacitive plasma generating plate, which conquers the defects of a generating plate being used currently. The utility model has the advantages that the continuous service life of the generating sheet is more than 5000 hours which is 5-8 times of the present products; an electrode and a chip are firmly combined, thereby, the phenomenon of falling off can never happen; the products have the same size, and the plasma generating capacity of unit area is 3-5 times of the present products, thereby, the service life of the plasma generator is lengthened; the failure rate is decreased; the energy consumption is reduced; the volume and weight of the complete appliance can be further reduced, providing foundations for adopting the new technique in large scale.

Description

Ceramic condenser type plasma generation sheet

Ceramic condenser type plasma generation sheet of the present utility model is the critical component of plasma generator (machine).Plasma generation sheet produces multiple plasmoid under the high energy electric field action, as ozonisation plasmoid O ₃, the HO of peroxide ion group ₂, the H of hydrogen peroxide ions group ₂O2 and hydroxyl ion group etc.; These ion clusters all have very strong oxidation, decomposition, disassociation and catalytic action to bacterium, virus, organic pollution etc., so can derive multiple technology and the product that environmental treatment, water treatment, offal treatment and the three wastes are handled that be used for, be an at present emerging in the world subject and technology.

The present plasma generation sheet that uses, its sparking electrode adopts platinum (Pt), aluminium (Al), copper (Cu), titanium materials such as (Ti) more, under the high energy electric field action, these electrode materials all do not reach 1200 hours life-span, exist a lot of shortcomings, such as: 1, the life-span shorter, general continuous use only reached about 1200 hours; 2, easily separated or come off at high energy effect of electric field bottom electrode and substrate; 3, the plasma on the unit are yields poorly, and makes the volume of equipment, weight excessive, has influenced the further promotion and application of product undoubtedly.

The purpose of this utility model is: improve the useful life of plasma generation sheet, improve the generating capacity of plasma, reduce the volume of equipment, cut down the consumption of energy, reduce cost.

The purpose of this utility model is achieved in that it is made up of (figure C.) ceramic substrate 1, sparking electrode 2, large electrode 3, magnifying electrode solder joint 4, large electrode solder joint 5.Wherein ceramic substrate 1 selection Jie constant is 60～80, dielectric loss coefficient＜1 * 10 ^-6, thickness=0.6mm high-purity AL2O3 pottery be substrate; Wherein the material selection semi-conducting material of sparking electrode 2 reaches sticking and agglomerated material, concrete prescription is: silicon dioxide-15%, molybdenum dioxide-8%, magnesium dioxide-5%, zirconia-6.5%, lead oxide-4%, tin ash-12.5%, ethyl cellulose-30%, terpinol-15%, borosilicate glass powder-3.5%, with above-mentioned material by behind the proportioning mixed grinding, make electric slurry, adopt the means of printing that electric slurry is imprinted on ceramic substrate 1 front, and being printed as needed figure, sparking electrode 2 should be than the little 2-3mm of ceramic substrate 1 back large electrode, 3 peripheral size; Large electrode 3 materials wherein, adopting palladium-Yin is main composition, the preparation electric slurry, concrete prescription is: palladium-3.5%, silver-40%, ethyl cellulose-42%, terpinol-10.5%, borosilicate glass powder-3.5%, with above-mentioned material by behind the proportioning mixed grinding, make electric slurry, adopt the means of printing that electric slurry is imprinted on ceramic substrate 1 back side, and be printed as needed figure; Behind printed preceding sparking electrode 2 of ceramic substrate 1 positive and negative and the large electrode 3, behind high temperature (855 ℃) sintering, sparking electrode 2, the large electrode 3 on ceramic substrate 1 and two sides are combined as a whole, and have extremely strong adhesive force, and sparking electrode 2 becomes the semiconductor-type electrode after pyro-oxidation-reduction; Wherein sparking electrode solder joint 4 and large electrode solder joint 5 adopt the stronger solder joint of low temperature class dot welding method processing weldability.

When using product of the present utility model, two

solder joints

4 and 5 that sheet takes place respectively weld out outside line, the output that connects high-frequency and high-voltage power supply, general voltage 3600V, frequency 25Hz, operating current 400MA-800MA is under the high energy effect of electric field, the edge of sparking electrode 2 produces corona, and the ionization ambient air produces plasma.Because the utility model adopts semi-conducting material, so the high anti-oxidation ability is arranged during its work, and sparking electrode 2 is changed the single-line type shape of the electrode in the present product, adopt large tracts of land along peripheral discharge type, discharge length has not only extended, and increased electrode area, obtained plasma output height, the advantage that electrode life is long.The utility model is under the high energy electric field action, and the periphery of sparking electrode 2 produces electrode and ionization, activates ambient air, produces antozone O ^-, ozonide ion cluster O ₂, the HO of peroxide ion group ₂, the H of hydrogen peroxide ions group ₂O ₂With the hydroxyl plasma, they are to all extremely strong oxidation, catalysis and dissociations of tool such as bacterium, virus, organic pollution, because plasma can be reduced into oxygen O automatically after sterilization, sterilization ₂With carbonoxide CO ₂And water H ₂O so do not produce secondary pollution and residual, is the most promising novel sterilization at present, the technology of sterilizing and curbing environmental pollution and product.

The utility model is compared with present product, has the following advantages:

1, sheet life-span 〉=5000 hour take place, be present product 3-8 doubly;

2, the output of plasma be present product 3-5 doubly;

3, electrode material has adopted semi-conducting material and the excessive sintering of glassy phase, combine with ceramic substrate 1 firmly,

Under the high temperature electric field action, never come off, be the regeneration product of present plasma generation sheet.
