Microwave-based thermal coupling chemical looping gasification method employing two sources, and device for same

A microwave-based thermal coupling chemical looping gasification device employing two sources, the device comprising the following components:

• a microwave radiation cavity;
• a loading recess of a microwave absorbing material filled with the microwave absorbing material;
• a quartz pipe reaction cavity between the microwave radiation cavity and the loading recess of the microwave absorbing material;
• the quartz pipe reaction cavity is driven to rotate by a motor;
• a first microwave generator consisting of a first magnetron, the first microwave generator is provided on a first outer side of the quartz pipe reaction cavity and located in the microwave radiation cavity;
• a second microwave generator consisting of a second magnetron, the second microwave generator is provided on a second outer side of the quartz pipe reaction cavity;
• and
• an infrared temperature-measuring probe group arranged at two ends of the first magnetron;
• wherein the loading recess is provided on the second outer side of the quartz pipe reaction cavity and located between the quartz pipe reaction cavity and the second microwave generator;
• two ends of the microwave radiation cavity are connected to a first three-way valve and a second three-way valve, respectively;
• the first three-way valve has a port A in communication with the ambient atmosphere;
• the second three-way valve has a port B in communication with a protection gas charging device for the microwave radiation cavity;
• the second three-way valve has a port A in communication with a port B of the first three-way valve via a pipeline;
• and a protection gas cooling device and a protection gas circulating fan are sequentially connected in series on the pipeline.
