Description
Technical Field
The invention belongs to the technical field of nuclear power, and particularly relates to a feeding device and method for supercritical water oxidation treatment of waste resin in a nuclear power plant.
Background
A certain amount of radioactive organic waste is generated in the operation and maintenance period of nuclear power plants and nuclear facilities, the radioactive organic waste contains radioactivity, pyrolysis and biodegradation easily occur, radiation harm can be brought to the public, and environmental pollution can be caused. At present, supercritical water oxidation technology is generally adopted to treat radioactive waste resin of a nuclear power plant so as to realize the inorganic and quantitative treatment of radioactive organic waste and effectively reduce the treatment and disposal cost of the radioactive organic waste.
The supercritical water oxidation technology is characterized in that the physical properties (such as special solubility, easily-changed density, lower viscosity, lower surface tension, higher diffusivity and the like) of supercritical water are utilized, an oxidant is added to enable organic matters to generate an oxidation reaction in a supercritical water environment, and the organic matters are converted into CO2And H2O and the like, thereby achieving the purposes of volume reduction and weight reduction. In the supercritical water oxidation technology, a supercritical water oxidation reactor is a core reaction device, water is heated and pressurized in the reactor to reach a supercritical state (the temperature is more than or equal to 374 ℃, and the pressure is more than or equal to 22.05MPa), and a reaction site is provided for oxidizing organic matters into inorganic micromolecular compounds; the feed pump provides and maintains a power source of the system in a supercritical state for supercritical water oxidation, and a high-pressure plunger pump (a piston pump or a diaphragm pump) is generally adopted to maintain the system in a supercritical pressure condition and continuously convey materials.
The supercritical water oxidation treatment of the waste resin is divided into three processes of resin degradation, dissolution and oxidation, wherein the time required for the resin degradation under the supercritical working condition is long (generally from several minutes to tens of minutes), and once the resin degradation is finished, the dissolution and oxidation reaction can be quickly finished, so that the waste resin feeding cannot enter a reactor in a large flow or batch manner. In addition, the feed pump is generally a high-pressure plunger pump, is not suitable for conveying media with particles, and is easy to precipitate on a feed pipeline under the working condition of low flow rate, so that the whole feed pipeline is blocked, even the whole supercritical water oxidation device has overpressure, and industrial safety risks exist.
In the related art, the waste resin is also crushed into small particles (several micrometers to several tens micrometers), but the crushed material is a radioactive medium, so that the sealing performance of the crushing device is high, and radioactive aerosol is easy to diffuse. The crushed waste resin particles are fed by a plunger pump, so that a continuous feeding process can be formed in a short time, but the waste resin particles cannot continuously run for a long time. In addition, since the temperature in the reactor is high, the waste resin is likely to cause clogging of the piping due to the wall sticking caused by the high temperature on the piping on the side of the feed piping close to the reactor.
In view of the above, it is necessary to provide a feeding device and method for supercritical water oxidation treatment of waste resin in nuclear power plant, which can continuously feed.
