Rotating flow distributor assembly for use in continuously distributing decontamination and regeneration fluid flow

摘要

The rotating flow distributor assembly comprises a cylindrical housing, with an inlet port and an outlet port, that receive and discharge the flow of fluid undergoing decontamination. The fluid passes into two flow distribution chambers located at either end of the housing, each of which houses a rotating flow diverter, which direct the fluid through the contaminant removal medium. Each flow distribution chamber is ringed by a set of openings distributed evenly around the circumference of the housing, through which the flow diverters distribute the fluid into the individual segments of the decontamination medium bed. Simultaneous with the distribution of contaminated fluid through the decontamination medium bed, the flow diverters direct regeneration fluid flow through the segments of the decontamination medium bed to remove the impurities from the contaminant removal medium. The rotating flow diverters are stepped through their 360 degree rotation in phase to sequentially regenerate a single decontamination medium bed segment at a time. The regeneration takes place in this single decontamination medium bed segment while the other decontamination medium bed segments are simultaneously accomplishing contaminant removal.
