Abstract
The utility model discloses a dielectrical barrier corona discharge reactor of a coaxial ray tube structure, which is characterized in that the reactor is composed of a filament electrode, barrier medium and an outer electrode in order from the inside to the outside. As the utility model adopts the structure which is composed of the filament electrode, the barrier medium and the outer electrode in order from the inside to the outside, the corona preionization generated around the filament electrode can decrease the air gap discharge field intensity under the action of the added AC high voltage, the barrier dielectric can restrain the forming of the arc discharge, and the uniform and stablemedium barrier corona discharge occurs in the reactor.
Description
Technical field
The utility model relates to a kind of discharge reactor, especially relates to a kind of coaxial line tube structural dielectric barrier corona discharge reactor.
Background technology
At present, dielectric barrier discharge (DBD) plasma commonly used has both at home and abroad obtained application in increasing occasion, but the uniform and stable discharge that realizes the aura form is very difficult, key issue is how to reduce the discharge field intensity makes discharge be in the electron avalanche stage, suppresses the development of discharge to the streamer stage.Existing conventional DBD reactor is difficult to realize uniform and stable discharge.
Summary of the invention
The purpose of this utility model just is to provide a kind of corona preionization that reduces the discharge field intensity, thereby makes the more uniform and stable coaxial line tube structural dielectric barrier corona discharge reactor of dielectric barrier discharge image.
The purpose of this utility model can realize by following measure:
It is followed successively by fine rule electrode, block media and external electrode from inside to outside the utility model.
External electrode in the utility model is the grounding electrode by copper conductor coiled tubulose.Block media adopts glass or resin or polytetrafluorethyletubular tubular dielectric.The overall diameter of block media pipe is 30～40mm, dielectric thickness 1～5mm.The fine rule electrode is a high-field electrode that diameter is 0.2～1mm that is fixed on the glass tube center that constitutes block media.Add alternating voltage effective value 10～20kV.
Advantage of the present utility model: adding under the ac high voltage effect, the corona preionization that produces around the fine rule electrode can reduce the bubble-discharge field intensity, block media can suppress the formation of arc discharge, occur uniform and stable dielectric impedance corona discharge in the reactor, thereby make the dielectric barrier discharge image more uniform and stable.
Description of drawings:
Accompanying drawing is a cross-sectional structure schematic diagram of the present utility model;
Embodiment
The utility model is described below the work with implementing in conjunction with the accompanying drawings:
As shown in the figure, the utility model integral body is tubular form, and its tubular cross-section is followed successively by fine rule electrode 3, block media 2 and external electrode 1 from inside to outside.External electrode is the grounding electrode by copper conductor coiled tubulose.Block media adopts glass or resin or polytetrafluorethyletubular tubular dielectric.The overall diameter of block media pipe is 30～40mm, can get 30,33,35 as required, 40mm; Dielectric thickness 1～5mm can get 1,2,3,4,5mm.The fine rule electrode is a high-field electrode that diameter is 0.2～1mm that is fixed on the glass tube center that constitutes block media, can get 0.2,0.3,0.5,0.7 as required, 1mm etc.
Operation principle of the present utility model is as follows: the utility model is owing to adopt the structure that is followed successively by fine rule electrode, block media and external electrode from inside to outside, adding under the ac high voltage effect, the corona preionization that produces around the fine rule electrode can reduce the bubble-discharge field intensity, block media can suppress the formation of arc discharge, occurs uniform and stable dielectric impedance corona discharge in the reactor.
