Method and device for recycling ruthenium by heating waste carrier carbon catalyst through microwave radiation

The invention discloses a method and a device for recovering ruthenium by heating a waste carrier carbon catalyst through microwave radiation, the method comprises the following steps: loading a ruthenium-containing carbon-supported catalyst in a quartz boat, placing the ruthenium-containing carbon-supported catalyst in a complete set of microwave tube furnace, setting temperature of the microwave tube furnace and a temperature measuring element to form interlocking, and automatically adjusting output power through microwaves when the temperature reaches a roasting temperature; under microwave radiation, the ruthenium-containing carbon-supported catalyst absorbs waves and is rapidly heated, and the oxygen enrichment concentration is controllable; a hydrochloric acid solution is used for primary absorption, and an alkali solution is used for secondary absorption; primary absorption liquid is adopted for roasting slag, hydrochloric acid is supplemented, and ozone is introduced into the three-hole flask; rutheni
