1Productivity
If traditional plasma gate devices use only two electrodes to generate plasma, then the device structure is simpler, but charge separation and ion manipulation efficiency is insufficient
Solution Approach 1:
The plasma generation process is segmented into distinct functional zones using three electrodes: a first electrode for initial plasma generation, a second electrode for charge separation, and a third electrode for ion manipulation. This segmentation allows each electrode to perform a specific function, improving overall charge separation efficiency while maintaining manageable structural complexity through functional specialization.
Solution Approach 2:
A dielectric barrier is introduced as an intermediary element between electrodes to enhance charge separation efficiency. The dielectric material accumulates charged particles and creates localized electric fields that improve plasma generation and charge separation without requiring direct electrode contact, thus enhancing productivity while controlling device complexity.
2Productivity
If high voltage pulses are applied to generate plasma, then plasma generation efficiency is improved, but energy consumption and risk of electrical breakdown increase
Solution Approach 1:
High voltage pulses are applied periodically rather than continuously to the electrodes. The pulse duration and frequency are optimized to generate sufficient plasma for nitrogen enrichment while minimizing energy consumption. The periodic action allows the plasma to be regenerated in cycles, maintaining high plasma generation efficiency during active periods while reducing energy consumption during idle periods between pulses.
Solution Approach 2:
The voltage, current, and pulse duration parameters are dynamically adjusted based on operational requirements. By changing these parameters, the system optimizes plasma generation efficiency for different application conditions while minimizing energy consumption and preventing electrical breakdown. The dielectric barrier also modifies the electric field distribution, allowing efficient plasma generation at lower peak voltages.

AI summary
A plasma gate device comprises a housing, a gas inlet, first and second dielectrics, and first, second, and third electrodes. The housing includes an internal reactor chamber. The gas inlet receives a source gas that flows to the reactor chamber. The first and second dielectrics are spaced apart from one another, with each dielectric including an upper surface and a lower surface. The two dielectrics are oriented such that the lower surface of the first dielectric faces the upper surface of the second dielectric. The first and second dielectrics form boundaries of the reactor chamber. The first electrode receives a first electric voltage. The second electrode receives a second electric voltage. The first and second electric voltages in combination generate an electric field in the reactor chamber through which the source gas flows creating a positive ion plasma and a cloud of electrons. The third electrode attracts the electrons.
