Centrifugal extractor with neutron absorption body

Abstract

A centrifugal extractor wherein a rotor is supported rotatably in a housing 10, an aqueous phase and an organic phase are supplied to the outer circumference of the rotor and mixed between the housing and the rotor, a mixed phase is sucked into the rotor and is separated into two phases in a centrifugal force field generated in the inside of the rotor, and the separated aqueous phase and organic pahse are discharged to an aqueous phase collector 50 and an organic phase collector 44, respectively. A cavity portion is provided in the center of the rotor, and a neutron absorption body 60 is disposed making use of the cavity portion. Preferably, a lower rotating and supporting mechanism (such as a sliding bearing 66) of the rotor is disposed, and a neutron absorption material is sealed into the lower rotating and supporting mechanism. By such a centrifugal extractor, criticality safety and durability can be enhanced, even when it is designed to be larger-size and larger-capacity.
