A self-propagating high-temperature synthesis system capable of solidifying radioactively contaminated sand

Abstract

The invention discloses a self-propagating high-temperature synthesis system capable of solidifying radioactively polluted sand, which includes a glove box, a laser generator, a sealed container, a paperless recorder and an exhaust gas treatment part. The outer wall of the glove box is provided with an aviation plug. The outer wall of the glove box is provided with an air inlet and a booster port, and the inlet ends of the air inlet and the booster port are respectively connected with a nitrogen cylinder through a pipeline, and the gas outlet of the glove box is connected with the exhaust gas through a pipeline. The processing part is sealed and connected, the top of the glove box is sealed with quartz glass, and the sealed container is located in the glove box. The patent of the present invention uses a specially customized glove box to isolate radioactive sand and protect experimental operators; The generator ignites the self-propagating material in the sealed container, which can realize non-contact ignition and reduce disturbance to polluted sand.

Description

technical field [0001] The invention relates to a self-propagating high-temperature synthesis system, in particular to a self-propagating high-temperature synthesis system that can solidify radioactive polluted sand. Background technique [0002] Self-propagation high-temperature synthesis (SHS for short), also known as combustion synthesis technology, is to use the self-heating and self-conduction of high chemical reaction heat between reactants to synthesize materials. A technology, once the reactant is ignited, it will automatically spread to the unreacted area until the reaction is complete. The current self-propagating high-temperature synthesis technology has the advantages of fast reaction, low energy consumption, simple equipment and convenient operation. It is widely used in the synthesis of ceramic materials, intermetallic compounds, high-tech structural materials and functional materials of high-temperature superconductivity, and in the field of curing radioactive...
