Abstract

A filter element (2) to be installed in a vessel (1) (pressure vessel or - in the case of vacuum systems - open vessel) includes a multiplicity of parallel filtrate channels (5) which are surrounded by filter medium (3). At the lower end, in the installed position, of the filtrate channels (5) is situated a first, transversely running collection channel (6) of smaller cross-section which serves for withdrawing the filtrate in normal filter operation. The upper ends of the filtrate channels (5), in the installed position, are connected together by a second collection channel (9) which has a larger cross-section and can serve for diverse purposes. One of these functions is feeding compressed air to the filtrate channels (5) for backflushing and detaching the filter cake. <IMAGE>
