A reactor of radioactive waste treatment device using a microwave heating

摘要

The present invention relates to a reactor of a radioactive waste treatment device using microwave heating, and more particularly, the crucible is configured in a ring-shaped cylindrical shape so that microwaves are irradiated to the center of the crucible and the outer circumferential surface of the crucible, It relates to a reactor of a radioactive waste treatment device using microwave heating that allows the waste to be uniformly treated within the crucible by limiting the waste to within twice the microwave penetration depth, and to expand the treatment capacity of the crucible. For this, a hollow outer body through which both sides are penetrated; a hollow inner body disposed inside the outer body and spaced apart from the outer body to form an inner space for accommodating radioactive waste; a water vapor input plate installed between the inner peripheral surface of the lower end of the outer body and the outer peripheral surface of the lower end of the inner body and having a plurality of through holes; and a heating chamber spaced upward from the water vapor input plate, the heating chamber including a seating plate having a plurality of through-holes formed so that radioactive waste can be seated, and providing an accommodating space for accommodating the outer body and the inner body; a plurality of first microwave irradiation means installed along the outer circumferential surface of the heating chamber and irradiating microwaves toward the outer circumferential surface of the outer body; and a second microwave irradiation means installed on the bottom surface of the heating chamber and irradiating microwaves toward the hollow inside of the inner body.
