Abstract
A recovery device comprising a sleeve (21) arranged in the outlet (15S) of a heat exchanger (10) and containing a filter assembly (24) capable of retaining solid cleaning materials (18) circulating through the heat exchanger. The filter assembly (24) comprises a rotary member (25) with a filter panel (26) and two interconnected pipes (27S, 27E) arranged on either side of the rotary member (25) in connection with the relative rotation thereof, as well as a circulation assembly for locally generating a counter-flow through the filter panel (26) of the rotary member (25) opposite the pipes (27S, 27E). The device is particularly useful in tubular heat exchangers used in condensers.
