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.
Claims10
A cleaning installation, for the cleaning of at least one heat exchanger that is linked, on one side, upstream to an intake duct for a fluid and, on another side, downstream to an outlet duct for the fluid,
- said cleaning installation comprising:
- system for recovering cleaning bodies in the fluid outlet duct after cleaning of said at least one heat exchanger by said cleaning bodies and for reinjecting said cleaning bodies into the fluid intake duct,
- wherein the system forms an assembly having at least one mobile member which is capable of being moved between several positions, including:
- a first position in which the system is configured to recover and contain cleaning bodies in said at least one mobile member, and
- a second position in which the system is configured, to take fluid from the fluid intake duct and, reinject, into said fluid intake duct, via said at least one mobile member and under the action of the fluid taken, cleaning bodies contained in said at least one member,
- wherein said at least one mobile member is a sheath mounted to slide inside an enclosure.
A system for recovering and reinjecting cleaning bodies in a heat exchanger, the system comprising:
- an assembly having an enclosure and at least one member which is mobile inside the enclosure, the enclosure having first and second openings, each coupled to a hydraulic link external to said enclosure, said at least one member having first and second openings and being capable of occupying several positions inside the enclosure, including:
- a first position in which said at least one mobile member, blocks first openings of the enclosure in order to prevent any connection between the interior and the exterior of the enclosure via said first openings and, matches some of the first and second openings of said at least one mobile member with the second openings of the enclosure in order to connect the interior and the exterior of the enclosure via the second openings,
- a second position in which said at least one member, matches other of said first and second openings of said at least one mobile member with the first openings of the enclosure in order to connect the interior and the exterior of the enclosure via the first openings and, blocks the second openings of the enclosure in order to prevent any connection between the interior and the exterior of the enclosure via these second openings,
- wherein:
- in the first position, the system is configured to recover cleaning bodies from a first fluid duct coupled to the enclosure and contain them in said at least one mobile member, and
- in the second position, the system is configured to, take fluid from a second fluid duct coupled to the enclosure and, reinject, into said second fluid duct, via said at least one mobile member and under the action of the fluid taken, cleaning bodies contained in said at least one mobile member, and
- wherein said at least one mobile member is a sheath mounted to slide inside the enclosure.
A method for recovering and reinjecting cleaning bodies in a heat exchanger via a coupled system, the system being an assembly having an enclosure and at least one mobile member inside the enclosure, the enclosure having first and second openings each coupled to a hydraulic link external to said enclosure, said at least one member having first and second openings, the method comprising steps of:
- displacement of said at least one mobile member inside the enclosure in order for the mobile member to occupy several positions, including:
- a first position in which said at least one mobile member, blocks first openings of the enclosure in order to prevent any connection between the interior and the exterior of the enclosure via said first openings and, matches some of the openings of said at least one mobile member with the second openings of the enclosure in order to connect the interior and the exterior of the enclosure via said second openings,
- a second position in which said at least one mobile member, matches other openings of said at least one member with the first openings of the enclosure in order to connect the interior and the exterior of the enclosure via said first openings and, blocks the second openings of the enclosure in order to prevent any connection between the interior and the exterior of the enclosure via said second openings,
- wherein said at least one mobile member is a sheath mounted to slide inside the enclosure.
