Microwave application reaction device and application method thereof

The invention relates to the field of chemical reaction devices, in particular to a microwave application reaction device and an application method thereof. The microwave application reaction device comprises a shell, a microwave source device, an isolation structure and a reaction tube, when the shell encloses to form anaccommodating chamber; the isolation structure is arranged in the accommodating chamber and is used for dividing the accommodating chamber into a non-wave-absorbing area and a wave-absorbing area; the reaction tube extends into the non-wave-absorbing area from one side of the shell; the microwave source device comprises a microwave antenna and a radio frequency microwave generating device, the microwave antenna is arranged in the accommodating cavity, the radio frequency microwave generating device is arranged outside the accommodating cavity, and the microwave antenna penetrates through the side, far away from the reaction tube, of the shell and is connected with the radio frequency microwave generating device; the microwave antenna transversely penetrates through the wave-absorbing area and the non-wave-absorbing area; and the reaction tube is made of a non-wave-absorbing material. The device is simple and compact in structure and ingenious in design, and has excellent application prospects in the field of chemical reactions.
