Microwave gas cracking device

Abstract

The invention provides a microwave gas cracking device, which is used for medical waste treatment. The microwave gas cracking device comprises a regulated power supply, a magnetron, an excitation chamber, an electromagnet, a high-stability signal source, a four-port circulator, a waveguide converter, a plasma generator, a gas flow regulator and an absorbing load, wherein the regulated power supply, the magnetron, the electromagnet and the excitation chamber form a microwave energy generator to provide microwave power needed for plasma generation; the high-stability signal source is used for providing stable 2450MHz microwave signals which are then injected into the magnetron through the four-port circulator, the oscillation frequency of the magnetron is controlled by the frequency of the injected signals, and the microwave energy is output to the plasma generator; the waveguide converter is arranged between a third port of the four-port circulator and the plasma generator and is used for converting the microwave energy output power; the gas flow regulator is connected with the plasma generator and is used for regulating the flow of gas entering the plasma generator; the magnetron is a magnetron with a low external quality factor.

Description

technical field [0001] The invention relates to the technical field of microwave equipment, in particular to a microwave gas cracking device of microwave treatment equipment for medical waste, which is used for purification treatment of waste gas from waste combustion. Background technique [0002] At present, domestic and foreign studies have found that microwave technology has the advantages of low energy consumption, short reaction time, simple operation, increased yield of reactants, and turning waste into treasure in terms of environmental pollution control, which has aroused the research enthusiasm of scientific research institutions and enterprises in various countries. [0003] Microwave plasma torch is a very important form of plasma generation. Microwave electromagnetic energy is used to generate plasma. Compared with electrode discharge, there is no problem of electrode evaporation pollution. The generation space of plasma is not limited by the gap between electrod...
