Microwave plasmatron with double-sided input of electromagnetic field energy into the gas flow

摘要

The utility model relates to microwave electrical installations for the formation of "cold plasma" in an inert gas flow at atmospheric pressure. The technical result is the possibility of using atmospheric pressure plasma for solving applied problems without using bulky vacuum devices, the use of discrete adjustment of the microwave power supplied to the plasma discharge, the use of auxiliary waveguide paths in the design of the microwave plasmatron for measuring, withdrawing and absorbing the microwave energy of the electromagnetic field ... The technical result consists in the possibility of forming a stable plasma discharge due to the two-way supply of the microwave energy of the electromagnetic field into the flow of an inert gas, with the combined use of a typical design of a waveguide path and commercially available microwave generators. Each of the two generators operates in a push-pull mode, and the design feature of the secondary power supplies of the generators allows discrete changes in the power supplied to the plasma. The unification of waveguide paths contributes to the conduct of exploratory research, with the participation of auxiliary equipment.
