Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0031] figure 1 It shows a schematic structural view of the radioactive waste resin recovery device provided in the specific embodiment of the present invention, figure 2 It shows a schematic diagram of the radioactive waste resin retrieving process flow. It can be seen from the figure that the device mainly includes a lead shielded sealed container 1 for transferring waste resin, a water ring vacuum pump 2 and a buffer tank 8. The upper end of the lead shielded sealed container 1 is It is connected with a feed pipe and a drain pipe, and communicates with the external waste resin storage tank through the feed pipe, and communicates with the upper part of the buffer tank 8 through the drain pipe; the upper part of the buffer tank 8 is also connected with a vacuum pipe, and the other end of the vacuum pipe is connected to the water ring The air inl...

Abstract

The invention relates to a radioactive waste resin recycling device and method, and belongs to the technical field of radioactive waste treatment.The device comprises a lead shielding sealed container, and the upper end of the lead shielding sealed container is communicated with a feeding pipeline and a drainage pipeline and is communicated with the upper portion of a waste resin storage tank and the upper portion of a buffer tank; the other end of the vacuum pipeline is connected with an air inlet of the water ring vacuum pump; under the action of negative pressure formed by the water ring vacuum pump, waste resin and free water in the waste resin storage tank enter the lead shielding sealed container through the feeding pipeline; a filter screen is arranged at the tail end of the drainage pipeline, and when the filter screen is buried by a mixed material of waste resin and free water in the lead shielding sealed container, the free water is discharged into the buffer tank through the drainage pipeline, so that the free water is drained. Waste resin and free water can be conveyed into the shielding container from the waste resin storage tank/groove, the free water is discharged from the shielding container, and the waste resin is retained in the closed shielding container to be safely transferred.

Description

technical field [0001] The invention belongs to the technical field of radioactive waste treatment, in particular to a device and method for retrieving radioactive waste resin. Background technique [0002] The safe disposal of radioactive waste resin containing organic matter is one of the difficulties and hot spots in domestic radioactive waste management. The radioactive waste resin generated from the operation of nuclear facilities is collected in waste resin storage tanks / tanks, and usually the waste resin contains a large amount of free water. [0003] At present, research on inorganic volume reduction treatment technology and equipment of radioactive waste resin is being carried out in China, including wet oxidation method, supercritical water oxidation method, steam reforming method, etc. These processes all involve retrieving the spent resin from storage tanks / tanks and transporting it to a nearby disposal facility, where it is transported as needed. At present, t...
