Mobile material decontamination apparatus

摘要

A technique for decontaminating material, including disposing a grid network of perforated pipes on a base, and covering the same with contaminated soil. A barrier layer is laid on the contaminated material and provided with a vent port coupled to a vapor disposal unit via a suction system. A source of heated gas is coupled to the grid system to force heated air through the contaminated soil and vaporize the contaminants. A mobile decontamination system includes an insulated container (464) having a top lid (470) for loading contaminated material in the container, and an insulated back door for removing decontaminated material. Apertured pipes (506) on the container floor convey a high temperature gas to the contaminated material to vaporize the contaminants. A suction system is coupled to a vapor outlet (526) of the container (464) to remove vaporized contaminants. The contaminated vapors are incinerated and either discharged as a harmless gas, or recirculated to the container for providing thermal energy and further vaporizing contaminants in the material.
