Abstract:
A fluid treating device comprising a number of vessels through which fluid is led, at least two feed pipes and at least two discharge pipes and a distributing device to control the flow of fluid from the feed pipes through the vessels to the discharge pipes, the distributing device comprising at least one revolving disc having an axis of rotation, and rotatably mounted in a stationary housing in sealing engagement with the periphery of the revolving disc, and a rotating device for rotating the revolving disc, said housing comprising two end walls and a side wall having an inner surface concentric with the rotating axis, and the feed pipes and the discharge pipes are connected to one end wall of the housing and open onto the revolving disc in said housing;wherein the stationary vessels are connected to said housing via connecting pipes and open onto the revolving disc, and the disc being provided with passageways, the feed pipes and the discharge pipes each opening into the passageways via at least one ring-shaped duct that extends in a closed circle around the axis of rotation such that for a number of positions of the disc each feed pipe, and discharge pipe is arranged for connection with at least one vessel; wherein the passageways inside the disc open onto the outer surface of the disc extending around the rotation axis, the connecting pipes from or to the stationary vessels are connected to the side wall of the housing and open onto said outer surface of the disc so that in said positions of the disc, one connecting pipe from a vessel is in fluid connection with one passageway, the one passageway being in fluid connection with one of the feed pipes or one of the discharge pipes through the intermediary of one of the ring-shaped ducts, or in fluid connection with another one of the passageways.
