摘要:
An apparatus and method are disclosed for removal of material from a substrate or structure using a broadband flashlamp-type radiator (200) for providing broadband radiant energy (204), an ultraviolet radiator (302), lamp head or other focusing means (212) for directing the broadband radiant energy (204) and ultraviolet radiant energy (306) onto the surface of the coating or coatings or other material to be removed, thereby resulting in the ablation and photodissociation of the material, and a residual constituents removing means (108), such as flowing CO2 pellets, liquid CO2, jets of compressed air, particles or other flowing gases or liquids.
摘要:
A reactor system for decontamination of water by photolytic oxidation utilizing near blackbody radiation is disclosed. The system comprises a reaction chamber housing (202) defining an internal space with an inlet (220) and an outlet (224); and a plurality of broadband radiators (230) generating radiant energy with wavelengths between about 150 nm and about 3 νm, the broadband radiators (230) disposed within the reaction chamber housing (202) such that a sufficient dosage of broadband radiation deeply penetrates the water matrix and irradiates the contaminants and/or the oxidant within the internal space of the reaction chamber housing (202) thereby causing photolytic oxidation of the contaminants.
