Abstract
The rotating flow distributor assembly comprises a connected pair of cylindrical housings, with an inlet port and an outlet port, that receive and discharge the flow of fluid undergoing decontamination. The fluid passes into flow distribution chambers located at the inlet end and outlet end of the assembly, 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 respective housing, through which the flow diverters distribute the fluid into the individual containers 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 a container 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 container at a time. The regeneration takes place in this single decontamination medium bed container while the other d…
