In Comparative Example 2, there is an air gap between the discharge electrode and the inner surface of the tubular dielectric 11. There is an internal discharge in the air gap, resulting in a large amount of heat generation, and the generator cannot continue to work (it will stop working after about 20 minutes of continuous operation). In comparative example 3, in the discharge electrode that the inner surface of tubular dielectric 11 is coated/plated conductive film, there is a large amount of air in the hollow cavity of tubular dielectric 11, there is internal discharge at the edge of the discharge electrode that conductive film forms, can cause Internal heating, and then the generator cannot work continuously (continuous work will stop working for about 30 minutes), and the processing of the coating/electroplating conductive film requires high temperature operation, which is easy to damage the structure and insulating properties of the tubular dielectric 11, and the coating/plating As the thickness of the conductive film increases, air bubbles or air segments are generated, thereby destroying the internal equipotential body structure. It is difficult to achieve a relatively thick coating/plating conductive film without bubbles or air segments in the ideal state. . In Comparative Example 4, the discharge electrode formed by filling the inner chamber of the tubular dielectric 11 with conductive paste (such as solder paste, etc.), in the smaller tubular dielectric 11, it is difficult to fill fully or fill up (the defective rate of the product is far higher In the embodiment of the utility model), there are air bubbles or air segments, which are easy to generate internal discharge, which will cause a large amount of internal heating. Under high temperature thermal expansion, the conductive paste may melt and flow, destroying the internal equipotential body, resulting in further discharge. Deterioration and instability, and then the generator cannot work continuously (it will stop working after about 25 minutes of continuous work). However, in the embodiment of the present invention, due to the porous molded body structure, the heating and thermal expansion of the generator will make the discharge electrode and the tubular dielectric 11 further closely contact, the discharge is more stable, and the long-term work can be sustainable and stable.

Specifically, the technical effect of the utility model is as follows:

(1) Enhanced environmental adaptability and expanded application scenarios: The discharge electrode pair composed of new electrode materials is skillfully packaged in the tubular dielectric 11, and the discharge method is changed from the corona discharge of Comparative Example 1 (generally, the discharge current density is small and uneven) It is converted into a new type of dielectric barrier discharge (discharge current density is large, uniform and stable), which is not only suitable for dry environmental conditions, but also suitable for high humidity environments and working in water, which greatly improves the environmental adaptability of its products and expands the application scenarios . Because it can generate a uniform discharge with a large current density, it has good biological safety, especially when special working media such as rare gases are used, the product can also be used for surface modification of materials, manufacturing of nano-medicine, medical cosmetology, tumor Adjuvant therapy and other biomedical fields.

(2) The generation dose and the activity of composite particles have been greatly improved: if the discharge electrode (referred to as comparative example 2) formed by inserting a rod-shaped conductor (such as copper wire, tungsten wire, etc.) into the inner cavity of the tubular dielectric 11 is used, the tubular dielectric 11 is required. The inner diameter of the rod-shaped conductor is larger than the outer diameter of the rod-shaped conductor (otherwise it is difficult to insert the rod-shaped conductor, and it is also difficult to remove the air and organic gas in the inner cavity), so that there is an air gap between the discharge electrode and the inner cavity of the tubular dielectric 11, resulting in a tubular Discharge in the inner cavity of the dielectric 11 brings about a series of problems such as oxidation and corrosion of the discharge electrodes, higher high-voltage voltage, unstable discharge, increased calorific value, and additional power consumption. The utility model adopts new electrode materials (fiber forming body, porous medium, elastic material or liquid) and a normal temperature packaging and filling method, and utilizes the surface characteristics of the fiber forming body, porous medium, elastic material or liquid (there are a large number of cilia, spikes, etc.) or protrusions), elastic deformation or fluidity, without destroying the surface characteristics and insulating properties of the inner cavity of the tubular dielectric 11, it is easy to realize the close contact package filling with the tubular dielectric 11, so as to form a cavity in the inner cavity of the tubular dielectric 11 The approximate equipotential body prevents the internal discharge of the tubular dielectric 11, ensures the stability of dielectric barrier discharge, and improves the dosage and energy utilization efficiency of highly active composite particles. At the same time, the ultraviolet irradiation unit and catalyst unit are used to further increase the dosage and activity of composite particles, reduce by-products, and enhance their biological safety.

(3) The safety and stability of the product are greatly improved: the product of the present utility model utilizes the tubular dielectric 11 of high dielectric constant sealed at both ends to cover and encapsulate the discharge electrode pair, protect the discharge electrode, and prevent electric shock and leakage (such as electric arc Discharge, glow discharge, etc.), while forming a roughly equipotential body in the inner cavity of the tubular dielectric 11, eliminating the internal discharge of the inner cavity of the tubular dielectric 11, and forming Stable and uniform dielectric barrier discharge, low working temperature (at room temperature or close to room temperature), sustainable and stable production of high-activity composite particles.

Any simple changes, equivalent replacements or modifications based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are covered by the protection scope of the utility model.
