Abstract: A cleaning installation of a heat exchanger includes a heat exchanger linked upstream to an intake duct for a fluid and downstream to an outlet duct for the fluid. A system is provided for recovering cleaning bodies from the outlet duct after cleaning of the exchanger by the bodies and for reinjecting bodies into the intake duct. The system includes a member capable of being displaced between a first position in which the system is configured to recover and contain cleaning bodies in the mobile member, and a second position in which the system is configured to take fluid from the intake duct and reinject, into this duct, via the mobile member and under the action of the fluid taken, cleaning bodies contained in the member.

Abstract: The invention concerns a system for intercepting and collecting bodies in a flow of a fluid, comprising: a pipe portion (18) comprising an inner face that defines an axial inner passage for the flow, a filtering surface (25) including an upstream face (25a) and extending transversely in the passage so as to intercept, by its upstream face, bodies conveyed by the flow whilst leaving exposed a plurality of collection openings (26a, 26b) between the filtering surface and the inner face, a cleaning device (30) that is arranged across from the upstream face (25a), the device (30) and the filtering surface (25) being in motion with respect to one another such that each zone of the upstream face is mechanically swept by the device during each alternating relative back and forth movement in order to orient the bodies intercepted by the upstream face (25a) toward the collection openings for said bodies.
