    摘要： An apparatus (1) for inertizing materials containing asbestos, whose particularity consists in that it comprises:
    - a unit (2) for granulating the material introduced in the apparatus, in order to give said material a uniform particle size distribution, ensuring the thermal absorption of the material in subsequent operations,
    - a preheating unit (3), which is arranged consecutively with respect to the granulation unit for the evaporation of the molecules of water contained in the material that exits from the granulation unit,
    - a dehydroxylation unit (4), which is arranged consecutively with respect to the preheating unit to eliminate the hydro-hydroxyl group that is present in the crystalline structure of the asbestos contained in the material that exits from the preheating unit,
    - a decomposition unit (5), which is arranged consecutively with respect to the dehydroxylation unit for the decomposition, by means of heat, of the material that exits from the dehydroxylation unit, modifying its crystalline structure into an irreversible amorphous structure,
    - a reheating unit (6), which is arranged consecutively with respect to the decomposition unit in order to raise the temperature of the exhaust gases produced by combustion and suppress volatile organic substances (VOS),
    - a filtration unit (7), which is arranged consecutively with respect to the reheating unit to suppress residual effluents before they are introduced in the atmosphere.

    摘要： A device and a method for removal of harmful substance capable of increasing a treating efficiency, eliminating the discharge of carbon dioxide gas, reducing the size of the device to reduce a production cost, and performing a heating treatment at a rather low temperature to reduce a running cost by heating a crucible (30) to a high temperature in a closed low pressure oxygenless state; the device, wherein a cooling container (82), traps (86c, 86b, 86a) for liquefying gas, and traps (94a, 94b, 94c) are installed between the crucible (30) and vacuum pumps (90, 98) to close passages between the crucible (30) and the vacuum pumps (90, 98) for generating suction forces, a screw (50) for inputting and outputting treated matter into and from the crucible (30) is installed, the treated matter is inputted into the screw (50) from an upper inlet member (58) for shielding the inside of the crucible from the outside, and the treated matter is discharged from the screw (50) through a lower discharge member (60) for shielding the inside of the screw from the outside, whereby the treating efficiency can be increased since the treated matter can be decomposed without opening the crucible (30).
