Problems solved by technology

However, this method has the following disadvantages: 1) the insertion loss of the matching circuit is relatively large, which will seriously reduce the energy efficiency of the scheme
2) In the commonly used microwave frequency band of 2450MHz, the power capacity of the lumped parameter circuit is relatively small
The application of this solution in the industrial and environmental protection fields is limited by the power capacity
3) The structure of the matching circuit of this scheme is complex

Abstract

The invention discloses a design scheme of efficient equipment based on a microwave nonlinear device. Microwave plasma has important application in the aspects of high-intensity light sources, microwave ultraviolet air sterilization and industrial waste gas treatment, plasma torches and microwave plasma propulsion. According to the invention, two resonant cavities which are connected in series are realized by adopting coupling screws, a rectangular waveguide, a circular waveguide, a coaxial line or other transmission lines, and the resonant frequencies of the resonant cavities respectively correspond to the operation frequency and the ignition frequency of the equipment. The microwave source firstly works at the ignition frequency and is successfully ignited, and then the frequency is changed to the operation frequency to efficiently operate. The equipment not only can be automatically ignited, but also can efficiently operate, and can be applied to the fields of disinfection and sterilization treatment of various gases and liquids, microwave plasma torches, microwave plasma vapor deposition, microwave plasma propellers and the like.
