Radioactive waste ion exchange resin rapid degradation device

Abstract

The invention relates to the radioactive waste processing technology field and especially relates to a radioactive waste ion exchange resin rapid degradation device. The device comprises a feeding system, a reaction system and a tail gas processing system. The reaction system comprises a reaction kettle and a microwave heating device which is installed on the outer side of the reaction kettle andis used for microwave heating. The reaction kettle is provided with a discharge port and an exhaust port. The feeding system comprises a catalyst feeding tank which is connected with the reaction kettle and supplies a material in an internal portion, a radioactive waste ion exchange resin feeding tank, and an oxidant feeding tank. The tail gas processing system comprises a first condensation pipeused for reflux condensation and a second condensation pipe used for vapor condensation which are successively connected. The air inlet of the first condensation pipe is connected to the upper end exhaust port of the reaction kettle. Compared with the prior art, by using the degradation device, a degradation speed is fast, volume reduction discharging can be realized, degradation and later periodcost is low, work efficiency is high, performance is stable and economic benefits are good.

Description

technical field [0001] The invention relates to the technical field of radioactive waste treatment, in particular to a radioactive waste ion exchange resin rapid degradation device. Background technique [0002] Ion exchange resin is a kind of high molecular polymer with certain flexibility, which is composed of skeleton and active group. Generally up to 10 7 ~10 13 Bq / kg, it cannot be reused and needs to be treated and disposed of as radioactive waste. Radioactive waste resin is one of the most important solid products in the operation of nuclear facilities at present. The annual output of waste resin in a conventional nuclear power plant is about tens of cubic meters, and its volume is close to 1,000 cubic meters in the average lifespan of 30-40 years. All countries in the world have conducted a lot of research on waste resin treatment methods, but there are few mature and ideal treatment methods. At present, most nuclear power plants store radioactive waste ion exchang...
