When used, the material is placed on the crawler-typed screen electrode; the rotating roller is used to drive the material on the crawler-typed screen electrode; the material passes through the plasma discharge area formed by the plate electrode and the screen electrode; at the same time, the gas blown from the gas distributor is fluidized through the mesh of the screen electrode, and eventually the material is handled with discharge.
Description
Technical field
The utility model belongs to the gas discharge technical field, is specifically related to a kind of atmosphere gas electric discharge device that is used for the generation and the control of plasma.
Background technology
In recent years, plasma technique has obtained using widely, as material surface modifying, surface clean, sterilizing etc.Low pressure glow discharge can produce even, stable plasma, has many good qualities, but be unable to do without vacuum system, costs dearly, and is difficult to continuous material handling, and this has limited this The Application of Technology.In order to serve various industrial applications better, people have developed multiple atmosphere gas electric discharge device.
In patent CN200420003865.5, introduced a kind of normal-pressure radio-frequency cold plasma generator, can produce stable, uniform cold plasma, can handle body surface.Do not have dielectric between two sparking electrodes of this device, therefore, its discharging gap generally can not surpass 5mm, and excesssive gap then is easy to generate arc discharge.This generator does not have successional material in-out apparatus, can only batch processing or install other feeding-discharging mechanism additional, and also the air-flow of radio frequency electrode pore directly blows to region of discharge, causes powder to disperse easily when handling dusty material.So, when handling dusty material, be difficult to continuously, stablize, evenly carry out.
Introduced a kind of plasma material treatment facility among the patent CN200420066560.9, it adopts the DBD discharge mode of fluidized-bed structure, can under atmospheric pressure handle continuously material, is particularly suitable for handling dusty material.But the air velocity of this device is divided into two stages: the fluidizing velocity in the processing procedure and dispose after carrying velocity.After disposing, also will add air flow could take powder out of.The variation of air-flow velocity can be disturbed the stability of powder fluidisation.During each charging, expend a period of time earlier and adjust the fluidizing velocity of powder, so that reach the fluidisation stable state.In fact, this also is a kind of batch processing mode.The fluidising chamber of this device is vertical cylindric structure, limit by gas discharge voltage and discharge power, and it is very big that fluidising chamber can not do, and is difficult to handle larger area tabular or film like material.
Introduce a kind of surface plasma source for atmospheric discharge among the patent CN01109211.4, had mesh electrode, can produce stable, uniform surface plasma at the mesh electrode lateral surface under the normal pressure, can produce fabulous effect when being used for handling material.But what this device utilized mainly is the plasma in the mesh electrode outside, and its energy only accounts for the seldom part of whole discharge energy, and the electric work power utilization is not high.When the powder that transports carbon black and so on conveyer belt was handled, powder was inactive state and is deposited on the conveyer belt, is difficult for handling evenly.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of and is suitable for multiple material and handles continuously, be particularly suitable for dusty material surface-treated, can under normal pressure, produce the gas discharge device of uniform and stable plasma.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise high-voltage ac power and the plate electrode that is connected with high-voltage ac power and silk screen electrode.Be characterized in, said silk screen electrode is a track structure, crawler type silk screen electrode is provided with the transfer roller that is used to drive its rotation, and also is provided with gas distributor in crawler type silk screen electrode, is provided with dull and stereotyped dielectric between plate electrode and the silk screen electrode.
Another characteristics of the present utility model are: high-voltage ac power is the radio-frequency power supply of 13.56MHz or 27.12MHz or the high-voltage pulse power source of 10-40kHz, and its voltage is adjustable continuously in 0-30kV; Crawler type silk screen electrode is formed by the conducting fibre braiding, and the aperture of silk screen is the 50-1000 order; The nozzle diameter of gas distributor is 0.05-1mm.
When the utility model applies voltage between plate electrode and crawler type silk screen electrode, crawler type silk screen electrode can produce higher electric field strength, therefore be easy to build-up of luminance, and crawler type silk screen electrode has intensive mesh of evenly arranging, can make the electric field strength stack and evenly arrange; Discharge has very strong perturbation action to the air-flow that gas distributor blows to the filament shape; Crawler type silk screen electrode can produce relative motion with plate electrode under the drive of transfer roller, can produce even, stable plasma in discharging gap, approaches uniform glow discharge; And plasma temperature is lower, adds the cooling effect of overdraught, has enlarged the range of choice of the material of handling.Crawler type silk screen electrode turns round under the drive of transfer roller, and energy continuous feed, discharging have improved operating efficiency.
