Microwave heating and dehumidifying device and rotary dehumidifier

The utility model discloses a microwave heating dehumidification device which is installed on a dehumidification channel surface of a dehumidification rotating wheel and comprises a heat preservationand insulation chamber for shielding electromagnetic waves, an electromagnetic shielding assembly, a microwave source module and a microwave source emitting head. The electromagnetic shielding assembly, the microwave source module and the microwave source emitting head are located in the heat preservation and insulation chamber, the microwave source emitting head faces the dehumidification rotating wheel, and the microwave source module controls the microwave source emitting head to emit microwave heating amount. Due to the selective heating characteristic of the microwave heating and dehumidifying device, water can be uniformly dried, extra heat energy loss is avoided, a corresponding container cannot generate heat, and the heat efficiency is high; the solid-state microwave source is combined with a temperature s
