Microwave reactor of coupled semicircular bent waveguide

The invention discloses a microwave reactor of a coupled semicircular bent waveguide. The microwave reactor comprises an electric controller, a waveguide and a reaction bin. The waveguide is semicircular and hollow, one end of the waveguide is closed, the electric controller is fixedly installed at the other end of the waveguide, and the electric controller is electrically connected with a microwave source. The inner side wall of the waveguide is fixedly connected with the reaction bin, and is provided with a plurality of gaps penetrating through the reaction bin. According to the invention, a semicircular waveguide is arranged, so that microwaves can be efficiently guided into the reaction container; the electric controller is used for controlling microwave emission, detecting temperature and giving a prompt; the wall of the reaction container can bear pressure; a pressurizing block provides pressure for a sealing cover, and guarantees the sealing environment; the reaction environment of the device is sealed
