Abstract
A substance such as radioactive liquid waste is heat treated using microwave by introducing the substance into a vessel made of a material reflective to microwave and containing spherical bodies made mainly of a material transmissive (i.e. transparent) to microwave. Microwave is applied to the substance while imparting movement to the spherical bodies. The substance is heat treated while in contact with the spherical bodies and is separated from the spherical bodies and pulverized by the friction and collision between the moving spherical bodies. An apparatus for carrying out the method is described.
Claims14
A heat treating method employing microwave which comprises:
- placing a plurality of spherical bodies mainly made of a material transparent to microwave in a vessel made of a material reflective to microwave;
- feeding a substance to be treated in a liquid form into the vessel and into contact with the spherical bodies;
- applying microwave to said substance in the vessel while imparting movement to the spherical bodies, whereby the substance to be treated is attached onto the surfaces of the spherical bodies and is heat-treated;
- and
- separating the thus heat-treated substance from the spherical bodies and pulverizing the substance due to the friction and collision between the adjacent moving spherical bodies.
A heat treating apparatus using microwave comprising:
- a closed vessel made of a material reflective to microwave;
- a grid partitioning the space in said vessel;
- a plurality of spherical bodies mainly made of a material transparent to microwave and positioned on the side of said grid toward a microwave guide;
- means for imparting movement to said spherical bodies;
- means for supplying a substance to be treated in a liquid form onto said spherical bodies;
- means for guiding microwave to the substance to be treated while attached onto the surfaces of said spherical bodies;
- and
- means for discharging the heat-treated substance which has been transferred through said grid to the other side of said grid.
