[Wnuk, Ralf, Chmiel, Horst] Leonrodstrasse 54, D-80636 München, DE Beschrieben wird ein Verfahren zur Regenierung von Adsorbern in einem vorzugsweise geschlossenen Kreislauf, in dem die adsorbierten Stoffe in einen Desorbatstrom desorbiert werden, aus dem die Stoffe entfernt werden, und der abgereichert dem Adsorber wieder zugeführt wird,Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, daß der gasförmige Desorbatstrom in mindestens ein Pervaporationsmodul geleitet wird, in dem die zu entfernenden Stoffe durch Gaspermeation über eine semipermeable Löslichkeitsdiffusionsmembran aus dem Desorbatstrom entfernt werden.＜img id="ia01" file="imga0001.tif" wi="85" he="105" img-content="drawing" img-format="tif" /＞

[TECKENTRUP HEINRICH, WNUK RALF DR ING, LANG NORBERT] DE The invention relates to a backwash filtering device using tubular wedge-wired screen elements (8, 42) which can be accommodated in a casing (30) comprising a filter inlet (32) and an outlet (4) for the liquid that is to be filtered. Liquid can flow through the filter elements (8, 42) in both directions for filtering (24) or backwashing (26). An actuatable washing arm (5) is provided for backwashing (26). Said arm has a liquid outlet (52) for contaminated liquid which can be successively displaced underneath the flow-through cross-sections (D) of the filter elements (8, 42). By providing at least part of the tubular wedge-wired screen elements used (8) with a conical design, a backwash device with improved filtering, enhanced backwash capacity and increased energy performance in relation to the liquid flow in said filter elements is thus obtained.

[HERGES KNUT, WNUK RALF] DE In a system for gas cleaning which has at least one casing (1) with a first chamber (31) into which the gas to be cleaned can be flowed, and with a second chamber (33) from which the cleaned gas exits, wherein a filter device (35) which can be flowed through by the gas is arranged between the chambers mentioned and has filter media both for the separation of solid particles and for dehumidifying the gas by separating out coalesced liquid, the system has, upstream of the filter device (35), an arrangement (11, 37) for preliminary dehumidification of the gas.

[Ralf Wnuk, Jörg Hermann Gerstner, Thomas Böttcher, Thomas Morawietz] DE Bexbach/Kleinottweiler A filtering apparatus with a plurality of filtering elements (11) which can be accommodated in a filter housing (1) having a filter inlet (7) for fluid to be filtered and a filter outlet (9) for the filtered fluid, wherein during the filtration operation, at least one of the filtering elements (11) can be back-flushed by means of a back-flushing device (45, 49) in order to dedust the effective filtering surface of said filtering element, the back-flushing device comprising a pressure control device (19) for assisting the back-flushing operation, is characterized in that the pressure control device comprises a hydraulic accumulator (19), the one fluid chamber (47) of which can be filled during the filtration operation with a quantity of dedusted fluid and can be connected for a back-flushing operation via a back-flushing guide (45) to the clean side (29) of the filtering element (11) to be dedusted, and in that, for a back-flushing operation, a further fluid chamber (48) of the hydraulic accumulator (19) can be subjected to a gas pressure in order, by means of a resultant movement of the separating element (59) of the hydraulic accumulator (19), to at least partially again dispense the filling amount of the dedusted fluid for the back-flushing operation from the first fluid chamber (47).
