<p>Disclosed is an apparatus which heats the waste to be treated continuously for a long time by light heating and detoxifies the waste by melting. A relation R/r=1.8 is set between the inside diameter (R) of a cylindrical tube (1) and the outside diameter (r) of rod-like waste (2) to be treated and, while controlling the supply rate of a movable device (3) by means of a controller (7), the rod-like waste (2) to be treated is supplied into the cylindrical tube (1) of quartz consisting of a material which is structurally stable at 1000°C or less and absorbs little energy for heat wave containing infrared rays and, while controlling the flow rate under the conditions of 20 l/min or more by means of the controller (7), air is fed from the bottom to top of the cylindrical tube (1) by means of a gas generator (5) in order to produce an air flow and, while controlling the power applied to a light source (41) by means of the controller (7), light from the light source (41) of a light heating mechanism (4) is condensed by means of a reflector (42) and then the rod-like waste (2) to be treated is locally heated and melted.</p> |
