Method and device for dynamic filtration

摘要

An overflow of the fluid stream fed to the concentrate chamber is formed from a stream or several partial streams (T1, T2, T3, T4). Either the single stream or one of the partial streams is introduced in a tangential flow direction on the outer casing (7) of the concentrate chamber. The concentrate stream is removed centrally to the central axis of the concentrate chamber. Process for the dynamic filtration of fluid materials comprises feeding a multiple phase fluid stream to a rotationally symmetrical concentrate chamber (1); feeding through a filter medium which covers the base and/or covering surface of the concentrate chamber; and separating into a filtrate and concentrate stream. An overflow of the fluid stream fed to the concentrate chamber is formed from a stream or several partial streams (T1, T2, T3, T4). Either the single stream or one of the partial streams is introduced in a tangential flow direction on the outer casing (7) of the concentrate chamber. The concentrate stream is removed centrally to the central axis of the concentrate chamber. An Independent claim is also included for a device for carrying out the filtration process. Preferred Features: At least two partial streams are introduced tangentially to the concentrate chamber. The partial streams are formed by branching from a main stream line.
