Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an unbalanced plasma generator. Background Art

[0002] Plasma is a state of matter composed of charged and neutral particles, typically generated at high temperatures. Non-equilibrium plasma refers to a state in which the electron temperature is higher than that of the ions and neutral particles. This state gives non-equilibrium plasma unique physical and chemical properties. Non-equilibrium plasma can be used to decompose harmful gases and pollutants, such as nitrogen oxides and volatile organic compounds.

[0003] Existing non-balanced plasma generators typically use quadrilateral grooves on the outer electrode plates. This simple structure can easily generate localized high electric field concentrations in corners, leading to uneven plasma distribution in these areas and affecting treatment efficiency and effectiveness. Furthermore, this structure has poor mechanical rigidity and stability, and is prone to deformation when subjected to external forces, compromising device stability. Utility Model Content

[0010] The second housing assembly includes a second upper housing and a second lower housing, and one end of the electrode plate assembly away from the inner terminal is disposed between the second upper housing and the second lower housing.

[0011] An inner fixing end extending out of the dielectric blocking plate is provided at one end of the inner electrode plate away from the inner terminal, and a corresponding fixing groove is provided on the second upper shell, and the inner fixing end abuts against the fixing groove.

Under the action of the electric field, the gas molecules in the medium are excited and ionized, thereby generating high-energy electrons, ions and other active substances, forming a non-equilibrium plasma. In the non-equilibrium plasma, the temperature of the electrons is much higher than the temperature of the gas molecules and ions, so it has extremely high chemical activity.

The dielectric barrier plate 4 is coated on the outer side of the inner electrode plate 30 to isolate and protect the inner electrode plate 30. The inner electrode plate 30 is designed with an internal terminal 5 extending from the dielectric barrier plate 4, which is convenient for connection with an external power supply to stimulate the generation of plasma. The outer electrode plate 31 is provided on the outer side of the dielectric barrier plate 4. The surface of the outer electrode plate 31 is provided with a plurality of honeycomb areas 7, and a plurality of honeycomb grooves 6 are distributed inside each honeycomb area 7. These honeycomb grooves 6 are hexagonal in shape, which helps to enhance the uniform distribution and reaction efficiency of the plasma.

[0029] according to Figures 3 to 6 As shown, the first housing assembly 2 includes a first lower housing 12 and a first upper housing 11. One end of the electrode plate assembly 1 is located near the internal terminal 5. The internal terminal 5 is located between the first upper housing 11 and the first lower housing 12, forming a tightly closed structure to ensure the stability and operating efficiency of the internal components. An external terminal 13 extending from the dielectric barrier plate 4 is provided on the side of the external electrode plate 31 near the internal terminal 5. An internal contact 14 and an external contact 15 are provided between the first upper housing 11 and the first lower housing 12, connecting the internal terminal 5 and the external terminal 13, respectively. This achieves electrical connection between the internal electrode plate 30 and the external electrode plate 31 and the external circuit, ensuring the normal operation of the plasma generator.

[0030] In addition, the second shell assembly 3 is composed of a second upper shell 16 and a second lower shell 17. The end of the electrode plate assembly 1 away from the internal terminal 5 is clamped between the second upper shell 16 and the second lower shell 17. The inner electrode plate 30 has an inner fixed end 18 extending from the dielectric blocking plate 4 at the end away from the internal terminal 5. A corresponding fixing groove 19 is provided on the second upper shell 16, and the inner fixed end 18 abuts against the fixing groove 19, ensuring that the electrode plate assembly 1 remains stable during the operation of the equipment, effectively preventing loosening or deviation caused by vibration or other external forces, and further improving the stability and reliability of the unbalanced plasma generator.

The first limiting retaining rib 24 is a horizontal bar provided at the upper and lower ends of the first lower shell 12, and the second limiting retaining rib 25 is a vertical bar provided in the second lower shell 17.

[0033] When the present invention is used, after the power supply is turned on, the current is transmitted to the inner electrode plate 30 and the outer electrode plate 31 respectively through the connected inner terminal 5 and the outer terminal 13. Due to the presence of the dielectric barrier plate 4, the current between the inner electrode plate 30 and the outer electrode plate 31 will not pass directly, but will generate an electric field. Under the action of the electric field, the gas molecules in the medium are excited and ionized, thereby generating high-energy electrons, ions and other active substances, forming a non-equilibrium plasma. In the non-equilibrium plasma, the temperature of the electrons is much higher than the temperature of the gas molecules and ions, so it has extremely high chemical activity. After the plasma is formed in the honeycomb area 7 of the electrode plate assembly 1, the hexagonal honeycomb grooves 6 guide the airflow, enhance the reaction effect of the plasma, and make the plasma evenly distributed on the entire electrode plate surface, thereby improving the working efficiency of the equipment.

[0034] The beneficial effects brought by the utility model are:

[0035] The utility model ensures that the plasma is evenly distributed on the entire surface of the electrode plate through the special structure of the honeycomb groove, while optimizing the conduction of the airflow and improving the reaction effect and processing efficiency.
