Online detection and sorting system and method for radioactive pollutants

Abstract

The invention relates to the technical field of radioactive waste treatment devices, and discloses an online detection and sorting system for radioactive pollutants. Through the synergistic effect ofa material distributing assembly and a transferring assembly, materials can be distributed and transferred to different positions, a feeding hopper is located in the middle of a conveying belt, a second radiation detector can be arranged at the upstream position for background measurement, environmental interference is eliminated to improve radiation detection reliability, interference is eliminated to improve the radiation detection reliability, and a mechanism for flattening the materials is further arranged between the feeding hopper and a first radiation detector to avoid stacking of the to-be-detected materials. In an online detection and sorting method for the radioactive pollutants, by controlling the beat of a motor and then combining the synergistic effect of the material distributing assembly and the transferring assembly, accurate demarcation of polluted materials and non-polluted materials can be ensured, thus fixed-distance operation of the conveying belt and batched sorting of the materials are realized, then reliable measurement and accurate sorting of online detection and sorting of the radioactive pollutants are realized, and the great popularization value and wideapplication prospects are realized.

Description

technical field [0001] The invention relates to the technical field of radioactive waste treatment devices, in particular to an online detection and sorting system for radioactive pollutants. Background technique [0002] With the rapid development of nuclear technology application in our country, a large amount of radioactive waste has been produced. How to safely and effectively dispose or utilize these wastes has become an increasingly difficult problem, and has even seriously restricted the sustainable and healthy development of nuclear energy utilization. [0003] In the field of radioactive waste treatment device technology, the state has invested a large amount of special funds to carry out research on major topics such as nuclear facility decommissioning and radioactive waste disposal. Among them, the cost-effective release control and disposal technology for batches of quasi-uniform granular radioactive pollutants is an important research One of the directions focus...
