Method for compacting and treating micro-radioactive waste

Abstract

The invention discloses a method for compacting and treating micro-radioactive waste. The method includes A, fixedly mounting a waste barrel on a barrel access slider outside a compaction cavity when a barrel access lifting door is opened; B, pulling the barrel access slider so that the waste barrel enters the compaction cavity to be in position; C, closing the barrel access lifting door, shifting a transition barrel mounted in the compaction cavity and enabling a lower opening of the transition barrel to match with an upper opening of the waste barrel; D, opening a feeding door and feeding materials into the waste barrel at one step; E, closing the feeding door, enabling a pressure head of a compactor to move downward, compact and maintain pressure; F, repeating the step D and the step E until waste in the waste barrel is sufficient when the pressure head ascends and returns, and stopping feeding; and G, lifting the transition barrel, opening the barrel access lifting door and pushing the barrel access slider to lead out the waste barrel. The method is simple in operation, operation steps are reduced, operation efficiency can be greatly improved, failure rate is reduced, the service life of equipment is prolonged, and radiation pollution to operators is reduced.

Description

technical field [0001] The invention relates to a waste mechanical packaging technology, in particular to a compaction treatment method for micro-radioactive waste. Background technique [0002] At present, domestic nuclear power plants mostly use imported (Russian, German, etc.) equipment for volume reduction and compaction treatment of waste. The main engine outside the hydraulic station is a box-type structure, and the external dimensions are mostly 5500L*1500B*5000H. The used compactors are purchased The period is more than one and a half years, and the price of a single machine is more than 500,000 US dollars. It not only requires the equipment department to have excellent foresight, but also uses excessive foreign exchange, which to a certain extent inhibits the development and promotion of compaction balers in this industry in China. The processing method of foreign equipment is to lay the track along the bottom of the length direction, and the track car barrel is fed...

AI Technical Summary

Problems solved by technology

During the compaction process, the barrel-carrying trolley bears the pressure of the press and transmits it to the track. At the same time, the barrel-carrying trolley frequently shifts and loads materials for compaction, which not only increases the complexity of the structure of the barrel-carrying trolley, increases the cost of construction, but also greatly Increased maintenance costs
