Abstract
Device for the ultrafiltration of a pressurized high-temperature liquid, having, inside a pressure resistant casing (1), a second casing (11) to which are fastened tube plates (15,16) carrying tubes (14) forming an ultrafiltration wall, and a first set of partitions inside the second casing (11) for channelling the flow of the filtrate. A second set of partitions (27) arranged in the casing (11) above the upper tube plate (16) and partitions placed in the casing (1) underneath the lower tube plate (15) make it possible to channel the fluid to be purified and the concentrate. The part of the filter which incorporates the tubes (14) can easily be removed. The fluid circulates at a constant rate in all parts of the filter.
