Description

Technical Field

[0001] The invention relates to a device for generating inductively coupled plasma, in particular to a facility mainly used for extending and strengthening a plasma energy beam. Background Art

[0002] Using plasma to modify objects can achieve many beneficial effects. At present, in the field of using plasma to treat objects, whether it is at room temperature and pressure or in a vacuum state, the surface of the object is modified and the depth is at the micron level. Even for materials with extremely low density, the depth of plasma treatment does not reach the centimeter level. If you want to deeply modify the original object, either the process cost is expensive - such as going into space, or the additional facilities are large, complex and expensive. Therefore, if there is a device that is simple to operate and has an acceptable price, it can modify objects at any time at room temperature and pressure. This will provide great convenience for the production of industry, agriculture and other industries, and will also produce huge social benefits. Summary of the invention

[0034] Example 1

[0035] As attached Figure 1 As shown, this embodiment provides a plasma generating device for processing an object, comprising:

[0036] The high-frequency resonant electric field capacity expansion system 1 comprises a first output terminal and a second output terminal, and is capable of outputting a pulsed current of a specific frequency.

[0037] The capacity-expanding electric field electrode group includes a capacity-expanding electric field cathode 7 connected to the first output end, and a capacity-expanding electric field anode 8 connected to the second output end.

[0038] The combined energy adding system body 3 is arranged between the capacity expansion electric field negative pole 7 and the capacity expansion electric field positive pole 8 and has an outlet 4 toward the capacity expansion electric field negative pole 7 and an inlet toward the capacity expansion electric field positive pole 8.

[0039] A hollow solenoid 2, used for generating a pulse electromagnetic wave 00-1 under the action of the pulsed current, which is arranged in the combined energy system body 3, and its axis extends along the direction from the inlet to the outlet 4;

[0040] The coupled plasma generator 5 is capable of generating plasma 00 - 2 and inputting the plasma into the inlet of the combined energizing system body 3 .

[0041] In a preferred embodiment, the frequency of the pulsed current output by the high-frequency resonant electric field capacity expansion system 1 is 2 kHz-20 kHz.

[0042] In a preferred embodiment, the coupled plasma generator 5 generates plasma while the high-frequency resonant electric field expansion system 1 outputs current, and inputs the plasma 00-2 into the combined energy system body 3 through the inlet.

[0043] In a preferred embodiment, an ellipsoidal expansion electric field 6 with a specific range can be formed between the expansion electric field negative electrode 7 of the expansion electric field electrode group and the main outlet 4 of the combined energy adding system, which is used to accommodate the object and provide plasma treatment with effective intensity.

[0044] Those skilled in the art will understand that because the energy at the edges of the electric field will be weakened, the effective electric field volume can only be removed from the edge part, that is, the rectangular block between the negative pole 7 of the expanded electric field and the main outlet 4 of the combined energy adding system is cut off from each side to make it rounded, becoming a shape similar to an ellipsoid.

[0045] In a preferred embodiment, the distance W between the negative electrode 7 of the expansion electric field and the outlet 4 of the combined energy system is 200 mm. According to the electrode size and current / voltage parameters, the volume of the ellipsoidal expansion electric field is between 100*200*100 and 400*200*400 from a top view.

[0046] According to the characteristics of plasma, plasma will change its original state of motion under the action of external forces. Experiments have shown that most plasmas 00-2 will increase their kinetic energy under the action of pulsed electromagnetic waves 00-1. They move in a high-speed and directional manner in the ellipsoidal expansion electric field 6. In this ellipsoidal electric field 6, as long as any substance is not absolutely high-density and there are nanometer-level gaps, the ions of the plasma will collide with the end faces of its molecules under the action of the electric field force, completing the plasma modification task in this process.

According to the right hand rule of Lenz's law, the frequency of the pulse electromagnetic wave 00-1 generated by the energized solenoid 2 is also 2kHz-20kHz.

[0051] Step S3, using the high frequency resonant electric field expansion system 1 to form an expansion electric field between the expansion electric field cathode 7 and the expansion electric field anode 8, thereby strengthening the energy of the pulse electromagnetic wave 00-1. Under the action of the expansion electric field between the expansion electric field cathode 7 and the expansion electric field anode 8, the electromagnetic wave 00-1 obtains huge energy.

[0052] Step S4, using the coupled plasma generator 5 to generate plasma 00-2, and inputting it into the combined energy system main body 3, so that the plasma 00-2 moves in a high-speed directional manner in the ellipsoidal expansion electric field 6 under the action of the pulse electromagnetic wave 00-1. The positive ions in the plasma 00-2 will move toward the negative pole 7 of the expansion electric field, and the electrons will move toward the positive pole 8 of the expansion electric field.

[0060] Step S3, using the high-frequency resonant electric field expansion system 1 to form an expansion electric field between the expansion electric field cathode 7 and the expansion electric field anode 8, thereby enhancing the energy of the pulse electromagnetic wave 00-1.

[0061] Step S4, using the coupled plasma generator 5 to generate plasma 00-2, and inputting it into the combined energy system main body 3, so that the plasma 00-2 moves in a high-speed directional manner in the ellipsoidal expansion electric field 6 under the action of the pulse electromagnetic wave. The positive ions in the plasma 00-2 will move toward the negative pole 7 of the expansion electric field, and the electrons will move toward the positive pole 8 of the expansion electric field.
