Description
Technical field
The present invention relates to multi-stage gas-liquid separation technology field, in particular it relates to a kind of Spiralism type multistage microbubble screening dress
Put.
Background technology
Thorium base MSR is so that its security is good, nuclear fuel long run supply, nuke rubbish minimize, production capacity is high, the anti-core of physics expands
The advantages that dissipating, turns into one of six kinds of candidate's heap-type of forth generation reactor nuclear power system.Energy caused by the thorium fuel of equal quality
Amount is 200-250 times of uranium fuel, and the reserves of thorium resources are 3 times of uranium resource in the earth's crust, particularly in China, thorium
Resource occupies second place of the world, and its reserves is about 6 times of uranium resource, and thorium base MSR has vast potential for future development in China.
MSR can constantly produce the fission gas such as radioactive krypton and xenon, these fission gas, tool in the process of running
There is larger neutron absorption cross-section, be referred to as neutron poison；And neutron is thorium base MSR can reach self-holding necessary condition,
Meanwhile these neutron poisons exist in fused salt in the form of microbubble, as the operation bubble of reactor is on the increase and is accumulated
It is tired, if removed not in time, the heat-transfer character of reactor can be had a strong impact on.In order to improve the utilization rate of thermal neutron and reactor
Stability, ensure the operation of reactor stability and high efficiency, it is necessary in MSR running, remove the fission gas such as krypton, xenon online
Body.
