The process flow of hot super compress technique is more complicated, reception, metering, grinding including radioactive spent resin,
The multiple working procedures such as drying, compression.In order to guarantee the processing capacity at Radwastes treatment center, meet production requirement, radioactivity
Disposal centre is provided with two sets of mutually independent grinding device (A series grinding device and B series grinding dresses in design
Set) it is respectively intended to grinding spent resin.The mixture of upstream spent resin particle and demineralized water has respectively entered A system according to a certain percentage
In the buffer tank of column grinding device or B series grinding device, after spent resin buffer tank reaches setting liquid level, starting resin circulation
Pump, spent resin comes out by buffer tank, successively by circulating pump and grinder returns buffer tank, loops back and forth like this, until grinding
Mill is completed.
According to initial design, the effect that two covering devices are arranged is on the one hand to come into operation simultaneously when handling peak period
Two covering devices guarantee the processing capacity of Radwastes treatment center radioactive spent resin；On the other hand for realization device
A preparation and a use can enable another covering device under the conditions of nominal situation when a set of grinding device failure, guarantee production activity
It is normally carried out.But the work of grinder catastrophic failure or circulating pump catastrophic failure when process of lapping carries out is not considered in design
Condition, at this point, these spent resins for not grinding completion will be unable to effectively export from the series, because not grinding the radiation of completion
Property spent resin cannot downstream system discharge, and the radiation level of spent resin is very high, if passing through the interim measures such as disassembly pipeline
Spent resin is exported to then time-consuming and laborious outside system, the personnel that also result in bear a large amount of unnecessary radiation and irradiate, it is important that
System is also unable to get on-call maintenance delay workshop and normally produces, for personnel safety, equipment safety and production safety, all
There are major safety risks.
Summary of the invention
The purpose of the present invention is to provide a kind of radioactive spent resin grinding system with redundant apparatus, which can
Ensure in two serial grinding devices because the reason systems such as equipment fault, disconnection fault lose grinding, conveying capacity leads to useless tree
