Microwave irradiation device, exhaust purification apparatus, automobile and management system

An exhaust purification apparatus comprising:

• a microwave irradiation device;
• a fine particle collection filter configured to collect fine particles contained in an exhaust gas, the fine particle collection filter serving as an object to be heated;
• a housing including a housing body covering the fine particle collection filter, and an inlet and an outlet of the exhaust gas coupled to the housing body;
• and
• a controller,
• wherein the microwave irradiation device includes:
• a housing configured to accommodate an object to be heated;
• a plurality of microwave resonators configured to be installed around the housing;
• a microwave conductor configured to couple the plurality of microwave resonators;
• a microwave generator configured to generate microwaves having different frequencies;
• and
• a microwave measurement circuit configured to couple to the housing or to the microwave conductor,
• wherein each of the microwave resonators resonates a microwave having a resonance frequency of the microwave resonator generated in the microwave generator and irradiates the resonated microwave to the object placed in the housing, and
• one microwave resonator and another microwave resonator among the plurality of microwave resonators have different resonance frequencies,
• wherein a microwave is irradiated from the microwave irradiation device onto the fine particle collection filter.
