Plasmas can be classified into thermal equilibrium plasmas and non-thermal equilibrium plasmas. In thermal equilibrium plasma, electrons and heavy particles (neutrals and ions) have the same temperature, and the temperature of macroscopic gases is about several thousands to ten thousand kelvin (K). On the other hand, in the non-thermal equilibrium plasma, the temperature of electrons, ions and neutral particles is greatly different, and generally, the temperature of electrons is much higher than that of other particles, the temperature of plasma depends on the temperature of heavy particles, and the temperature of heavy particles is close to room temperature, so that such plasma is also called cold plasma, and is also called atmospheric pressure cold plasma (CAP) because it can be generated under atmospheric pressure.

Therefore, the current atmospheric pressure cold plasma creeping discharge device is not enough in the aspects of working stability, safety and portability, and plasma generated by creeping discharge is inconvenient to be directly utilized or studied.

The portable uniform plasma creeping discharge device comprises a power supply system and a dielectric barrier discharge structure, wherein the power supply system provides high voltage required by discharge for the dielectric barrier discharge structure, and the power supply system and the dielectric barrier discharge structure are integrally packaged into a cylindrical structure, as shown in fig. 1.
Dielectric barrier discharge structure
The dielectric barrier discharge structure occupies only a small portion of the volume, and the radial dimension of the dielectric barrier discharge structure is matched with a shell for accommodating a power supply system, as shown in fig. 2 and 3.
The dielectric barrier discharge structure comprises an annular base, a grid type ground electrode, a dielectric plate, an annular pressing ring and a rear cover, as shown in fig. 4. Specifically, the method comprises the following steps:
the annular base is axially divided into two sections of annular cylinders with different inner diameters, so that an annular table top is formed at the bottom of the inner side of the annular base, the annular cylinder above the annular table top is an A-section annular cylinder, the annular cylinder below the annular table top is a B-section annular cylinder, and the A-section annular cylinder is provided with internal threads;
the grid type ground electrode, the dielectric plate and the annular pressing ring are sequentially arranged in the annular base along the axial direction, wherein the radial sizes of the grid type ground electrode and the dielectric plate are both larger than the inner diameter of the annular table top, the grid type ground electrode is placed on the annular table top, the grid type ground electrode covers the front surface of the dielectric plate, and the double-conductive copper foil adhesive tape is pasted on the back surface of the dielectric plate to serve as a high-voltage electrode; the annular clamping ring is provided with an internal thread and an external thread, the external diameter and the external thread of the annular clamping ring are matched with the internal diameter and the internal thread of the section A annular cylinder, and the internal diameter and the internal thread of the annular clamping ring are matched with the diameter and the external thread of the rear cover. During assembly, the annular pressing ring is screwed into the annular base to press the dielectric plate, the back cover is screwed into the annular pressing ring, the back cover is screwed to the lug (prism) on the back cover, and finally the back cover is pressed tightly on the high-voltage electrode connected with the lead (the lead is reliably contacted with the high-voltage electrode).
As shown in fig. 4 and 5, the rear cover is provided with a wiring hole for leading out a lead of the high voltage electrode.
As shown in fig. 6, the wires of the mesh type ground electrode may be led out along the side wall (inner or specially provided axial groove) of the annular base.
Preferred structural parameters are as follows:
section A annular cylinder: the outer diameter is 120mm, the inner diameter is 100mm, and the height is 10 mm; the inner wall is provided with internal threads;
b section annular cylinder: the outer diameter is 120mm, the inner diameter is 80mm, and the height is 10 mm;
an annular table top: the outer diameter is 100mm, and the inner diameter is 80 mm;
annular clamping ring: the outer diameter is 100mm, the inner diameter is 80mm, and the height is 10 mm; the inner wall and the outer wall are both provided with threads;
a rear cover: the diameter is 80mm, the height is 10mm, and a through hole (wiring hole) is arranged in the center.
The embodiment also optimizes the material selection and thickness parameters of the dielectric plate. In the development process, two materials, namely polytetrafluoroethylene and epoxy resin, are selected for the dielectric plate, and the dielectric plate has the characteristics of good insulation and strong oxidation resistance. And further, a 10kHz sine power supply is connected between the high-voltage electrode and the ground electrode, and the initial discharge voltage of the dielectric plate made of different materials and with different thicknesses is recorded through an oscilloscope and a high-voltage probe. As shown in table 1.
TABLE 1 initial discharge voltage for different materials and different thicknesses
It can be seen that the initial discharge voltage of polytetrafluoroethylene is higher than that of epoxy resin at the same thickness, and the smaller the thickness, the smaller the initial discharge voltage at the same material, which is consistent with the results of the previous theoretical analysis. Although the discharge voltage of the epoxy resin is relatively low, in the experimental process, the epoxy resin material can be obviously sensed to generate heat seriously when being used as a dielectric plate to discharge through direct touch of hands, the temperature rises very fast, thermal breakdown is easily caused, and the temperature of the polytetrafluoroethylene material changes slowly in the discharge process.
In the experiment, the polytetrafluoroethylene and the epoxy resin with the thickness of 0.8mm are tested, and the area of a discharge area is 50cm2The temperature change condition when a sine alternating current power supply with the frequency of 10kHz and the voltage of 7.5kV is additionally arranged between the high-voltage electrode and the ground electrode is measured directly at a position 30cm away from a discharge area by using an infrared thermometer, and the test result is as follows: the temperature of the polytetrafluoroethylene dielectric plate rises slowly, rises about 10 degrees after discharging for 180s, and rises more and more slowly along with the increase of time, so that the balance of heating and heat dissipation is achieved; the temperature of the epoxy resin medium plate rises very fast, the temperature rises by 25 ℃ within 60s of discharge, and the rising trend is kept unchanged all the time.
After the consideration of the final heat generation and the initial discharge voltage is combined, a polytetrafluoroethylene material with the thickness of 0.8mm, which generates relatively less heat and has lower initial discharge voltage, is selected as the dielectric plate.
Annular base, annular clamping ring and back lid also all can use polytetrafluoroethylene material to make, and the annular mesa in the annular base is placed earlier and is tailor to the stainless steel hexagon net of suitable size as ground electrode, places the dielectric plate above that again, and the another side of dielectric plate pastes two copper foil sticky tapes as high voltage electrode, draws forth the wire through the wiring hole of back lid by high voltage electrode.
Second, power supply system
As shown in fig. 7, the power supply system includes a rechargeable battery, an inverter, and a high voltage module electrically connected in sequence. At present, the actual output of two output ends of a common miniaturized high-voltage module is high voltage relative to the ground, a plurality of high-voltage modules are tested and compared in the development process, the finally adopted high-voltage module is AC input with the voltage of 50mm multiplied by 85mm multiplied by 30mm, 220V and 50Hz, the output is sine-like wave, the waveform is saw-toothed, the output peak value of one end is 3.1kV, the output peak value of the other end is 2.9kV, the output frequency of two ends is the same, the output frequency is about 15kHz, and the directions are opposite. If the potential of the ground electrode is always regarded as zero potential, the high-voltage electrode can be regarded as a high-voltage high-frequency power supply which is connected with a frequency of 15kHz, has a peak-to-peak value of 6kV and has a waveform similar to a sine wave, and is shown in figure 8.
The hand drill lithium battery (36mm multiplied by 40mm multiplied by 80mm, 3800mAh) is adopted to supply energy to the whole equipment, the direct current 12V is output, the charging and discharging can be carried out for many times, the overcurrent protection is realized, and the plugging and pulling during the charging and discharging are also convenient.
In order to match the direct current output of the battery with the alternating current input of the high-voltage module, the inverter is selected as rated direct current 12V input, 220V and 50Hz alternating current output, overcurrent protection, short circuit protection, overload protection and maximum power of 100W are provided, the red and green indicating lamps can display the working state of the inverter in real time, the working voltage is 10V-16V, the inverter normally works at the moment, the green lamp is on, the output voltage fluctuates around 220V and does not exceed the range of plus or minus 8V, the inverter does not work when the input voltage is less than 10V or more than 16V, and the red lamp is on.
The highly integrated powerful and comprehensive inverter carries most of the protection functions of the whole device, such as current limiting protection, overload protection, short circuit protection and undervoltage protection, and is also used as an indicator of the working state of the whole device.
In order to detect the uniformity of the creeping discharge, firstly, a discharge area is directly observed, when the discharge is considered to be uniform and the work is stable, the distance between the optical probe and the discharge area is kept unchanged by 30cm, under the condition that the external conditions such as temperature, light intensity and ventilation are the same, six points are randomly selected in the discharge area, and the emission spectra of the points are measured and compared. As shown in fig. 9, the emission spectrum images of the randomly selected six points are substantially the same, and the intensity of the emission spectrum of each particle is approximately similar, so that the uniformity of the surface discharge of the device is considered to be good, and the phenomenon of overheating does not occur even after long-time discharge.
