Embodiment Construction
[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0016] combine figure 1 , the present invention mainly includes a low-temperature plasma discharge assembly, an oil filter assembly 12, a swirler assembly, and a fuel atomizing nozzle. The low-temperature plasma discharge assembly mainly includes: an outer electrode 5, a ceramic barrier medium 3, an inner electrode 2, a power connection frame 1, and a graphite sealing ring. The ceramic barrier medium 3 is designed in a top-closed mode, and the graphite sealing ring 4 is used to achieve sealing with the outer electrode 5, and the inner electrode 2 is in it, which can effectively avoid arc discharge at the end and ensure the discharge uniformity and stability of the discharge area; ceramics are used as the barrier The medium can effectively prevent discharge breakdown and improve the service life of the plasma-enhanced atomizing nozzle. A discharge area is formed b...

Description
technical field [0001] The invention relates to a gas turbine, in particular to a nozzle of the gas turbine. Background technique [0002] Dielectric barrier discharge technology is a kind of low-temperature plasma catalysis, which is currently mainly used in technical fields such as ozone production, waste gas treatment, material surface modification, and gaseous pollutant treatment. Low-temperature plasma catalysis is an extremely effective way to achieve low energy consumption, high yield, and high selectivity in plasma chemical reactions. [0003] Dielectric barrier discharge technology is mostly used in the research and treatment of gaseous objects, but less research is done on the catalysis of liquid objects. Ye Qizheng, Li Jin and others used the dielectric barrier discharge device to study the gas discharge water treatment technology on the surface of the liquid film. Yin Yongxiang used the dielectric barrier discharge device to act on the bubbles in the water. When...
