The utility model relates to the technical field of industrial reactors, in particular to a tubular
microwave reactor. The tubular
microwave reactor comprises a reaction pipeline, a
microwave unit, a bearing platform, a rotary driving mechanism, a dip angle adjusting mechanism and a shoveling plate mechanism. The rotary driving mechanism is used for driving the reaction pipeline to rotate so as to guide the
solid reaction materials to longitudinally overturn in the reaction pipeline. The inclination angle adjusting mechanism is located below the bearing platform and used for adjusting the inclination angle of the reaction pipeline so as to guide the
solid reaction materials to transversely move along the reaction pipeline. The shoveling plate mechanism is arranged along the central axis of the reaction pipeline, protrudes out of the surface of the inner wall of the reaction pipeline and is used for shoveling the
solid reaction material at the bottom of the reaction pipeline. According to the microwave reaction kettle, materials can be uniformly distributed in a reaction pipeline, insoluble solid materials and liquid reaction materials can be fully mixed, and the reaction can be relatively quickly and thoroughly completed under the action of microwaves.
