Microwave liquid phase plasma generator

Abstract

The invention discloses a microwave liquid phase plasma generator comprising a microwave discharge electrode, a fixed disk and a microwave input connector, wherein the bottom end of the microwave discharge electrode is movably connected with the top end of the microwave input connector through the fixed disk, the microwave discharge electrode is sequentially composed of an electrode inner conductor, a ceramic pipe and an electrode outer conductor from interior to exterior, the electrode inner conductor, the ceramic pipe and the electrode outer conductor are parallel in the axial direction, the ceramic pipe is sleeved on the outer side wall of the electrode inner conductor, and silicon gel is evenly filled in the gap between the ceramic pipe and the electrode outer conductor. The microwave input connector is sequentially composed of an input connector inner conductor, a sealing fixing block and an input connector outer conductor from interior to exterior, the input connector inner conductor, the sealing fixing block and the input connector outer conductor are parallel in the axial direction, and the input connector inner conductor is connected with the input connector outer conductor in a sealing mode through the sealing fixing block. The microwave liquid phase plasma generator is not only convenient to detach, but also easy to operate; meanwhile, through adjusting of the length of the ceramic pipe, adjusting of impedance of the discharge electrode can be achieved, and impedance matching of the discharge electrode and a feeder line is good.

Description

technical field [0001] The invention relates to a microwave liquid phase plasma generating device. Background technique [0002] Plasma is the fourth state of matter, and it is widely used in environmental protection and material synthesis because it contains high-energy active particles. The main way of plasma generation in the traditional concept is gas physical discharge such as glow discharge, arc discharge, and microwave gas discharge in the gas phase. There are restrictions. Because microwave discharge plasma has the characteristics of large spatial distribution and relatively high density, it is widely used in plasma deposition and other fields. Extinguished, limited for high water vapor applications. In addition, the application of gas-phase plasma in liquid phase has always been an important problem that has plagued experts at home and abroad due to the problem of gas-liquid conversion efficiency. In recent years, many experts at home and abroad strive to genera...
