The measure of cleaning the media sheet in the present invention is divided into two steps: cleaning the medium sheet on line without stopping by adopting a microwave plasma cleaning mode of an online microwave plasma cleaning device; along with the production going on, the increase of washing number of times, the stubborn pollutant that is difficult to be washd accumulates gradually, and when the microwave plasma cleaning mode can not reach ideal clean effect, rubber powder microwave desulfurization equipment shut down, utilizes medium piece automatic change belt cleaning device to carry out the automatic change to the medium piece, and the off-line is washd. The cleaning process of the media sheet is shown in fig. 4.
In one embodiment of the present invention, as shown in fig. 5, the online microwave plasma cleaning device includes a discharge portion and a telescopic mechanism, the discharge portion includes a plurality of metal needles 18, one end of each metal needle 18 is fixed on an arc-shaped plate 19, and the other end of each metal needle 18 can enter the inside of the microwave guide tube 13 along a pinhole on the side wall of the microwave guide tube 13; the arc-shaped plate 19 is connected with a telescopic mechanism, and the telescopic mechanism is connected with a controller; the metal needle 18 can ionize air in the microwave guide pipe 13 and introduced argon gas in the discharging process to generate oxygen plasma and argon plasma, and pollutants on the surface of the medium sheet can be removed. In fig. 5, the number of the metal needles can be designed according to the actual situation (the figure is only schematically illustrated); the telescopic mechanism comprises a turntable 20 and a driving part (not shown in the figure) controlled by a controller, the driving part can adopt a micro motor, the surface of the turntable 20 and the bottom of the arc-shaped plate 19 are both provided with threads, and the arc-shaped plate 19 is in threaded fit with the surface of the turntable 20.

The oxygen plasma makes the non-volatile organic matter adhered on the medium sheet changed into volatile water vapor and carbon dioxide through chemical reaction; the argon plasma is attracted by the medium sheet under the action of external bias voltage, is accelerated to generate kinetic energy under the action of the electric field force of the medium sheet, and then bombards the surface of the negatively charged medium sheet, so that microparticle pollutants are removed. Among them, the particles generated by the ionization of argon are heavier, and the kinetic energy of argon ions is higher than that of other inert gases under the action of the electric field.
The medium sheet is pre-acted by strong external electric field to generate polarization phenomenon, the polarization charge is permanently existed on the surface and in the dielectric medium body and does not disappear along with the removal of the external electric field, and the medium sheet can generate electrostatic acting force under the condition of no external electric field.
