Problems solved by technology

[0003] Internationally, the methods of treating high-fluorine materials by dry process are similar. According to past production experience, this process has the following disadvantages in the process of returning high-fluorine materials to the furnace: 1. The switching between the production of high-fluorine materials and the production of regular materials is complicated and

Example Embodiment

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] like figure 1 As shown, a device for processing high-fluorine materials provided by the present invention includes a vacuum valve 1, a nitrogen blowback valve 2, a feeding valve 3, a feeding valve 4, a filter 5, a temporary storage bin 6, and a reaction bin 7 and purge valve 8. One end of the emptying valve 8 is communicated with the material inlet a, the other end of the emptying valve 8 is communicated with one end of the feeding valve 3, and the other end of the feeding valve 3 is communicated with the sidewall of the temporary storage bin 6 through a pipeline. One end of the vacuum valve 1 communicates with the vacuum valve port b through a pipeline, and the vacuum valve port b communicates with the vacuum unit. One end of the nitrogen blowback valve 2 is communicated with the nitrogen inlet c through a pipeline, and the nitrogen ...

Abstract

The invention belongs to the field of nuclear fuel processing and particularly discloses a device and method for treating high-fluorine materials. The device comprises a vacuum valve, a nitrogen back-blowing valve, a feeding valve, a discharging valve, a temporary storage bin, a reaction bin, an emptying valve and a filter. The method comprises the step that opening and closing of all the valves are designed during the evacuation time T1, the sucking time T2, the emptying time T3, the evacuation time T4, the vacuum breaking time T5, the discharging time T6, the positive pressure maintaining time T7 and the waiting time T8, and therefore sucking and treating of the high-fluorine materials are achieved. By the adoption of the device and method, the high-fluorine materials can be treated safely at the low cost through full-automatic operation.

Description

technical field [0001] The invention belongs to the field of nuclear fuel processing, and in particular relates to a device and method for processing high-fluorine materials. Background technique [0002] In the process of uranium dioxide powder production, due to various reasons, a certain amount of unqualified materials with excessive fluorine content will inevitably be produced; due to its own characteristics, the dry process production line has a different way of handling high-fluorine materials than the normal material production process. Dry processing of high-fluorine materials requires the use of a set of charging equipment to re-send the materials into the furnace for defluorination. The traditional dry method is composed of a hopper and a feeding screw. This set of equipment is not used in the production of the main material. The connection between the reaction chamber and the returning material device is sealed with a flange. When high-fluorine material treatment ...
