The invention discloses a partitioned energizing atmospheric-pressure non-equilibrium plasma generator, which belongs to the technical fields of gas discharge and application. The plasma generator disclosed by the invention is technically characterized in that an atmospheric-pressure flat-plate type DBD (dielectric barrier discharge) reactor is provided with a small-sized high-frequency & high-voltage transformer, and a high-voltage output end of the small-sized high-frequency & high-voltage transformer is connected with the atmospheric-pressure flat-plate type DBD reactor by a fast-acting fuse, thereby forming an atmospheric-pressure non-equilibrium plasma generating unit module; and ten to hundreds of atmospheric-pressure flat-plate type DBD non-equilibrium plasma generating unit modules are assembled in parallel so as to form a partitioned energizing atmospheric-pressure non-equilibrium plasma generating array, the array is provided with energizing energy by a low-voltage & high-frequency inverted power supply, then, the energizing energy is distributed to each independent atmospheric-pressure flat-plate type DBD reactor by using the small-sized high-frequency & high-voltage transformer. The partitioned energizing atmospheric-pressure non-equilibrium plasma generator disclosed by the invention has the advantages that the inherent resonant frequency of the atmospheric-pressure non-equilibrium plasma generating array can be improved, and the discharge performance of the non-equilibrium plasma generating unit can be optimized.
Description
technical field [0001] The invention belongs to the technical field of gas discharge and application, and relates to a non-equilibrium plasma generation system based on atmospheric pressure dielectric barrier discharge, in particular to a partition excitation type atmospheric pressure non-equilibrium plasma generation device. Background technique [0002] Dielectric barrier discharge is the most feasible method to generate atmospheric pressure non-equilibrium plasma, and it has been used in the field of industrial ozone synthesis for more than 100 years. From the perspective of principle and structure, atmospheric pressure dielectric barrier discharge can be divided into two basic structures: coaxial circular tube type and parallel plate type. At present, the coaxial circular tube structure is mainly used in industrial applications. The atmospheric pressure dielectric barrier discharge non-equilibrium plasma generation system based on this structure principle is usually comp...
