Definitions

  • the invention relates to a device for cleaning a fluid system.
  • the chemical and / or biological contamination of the aqueous cooling agents used for tempering contaminates the liquid-wetted surfaces of the fluid system with the serious disadvantage of a poor temperature control, due to the poor heat transfer.
  • the present invention has for its object to provide a rinsing system for cleaning a fluid system that is structurally simple and avoids the above disadvantages.
  • the system according to the invention is connected to the fluid system. Especially in stationary facilities such. Heat exchangers or heavy molds is advantageously used a mobile system with flexible flushing hoses.
  • the rinsing system is first brought into spatial proximity of the fluid system and connected there by means of couplings.
  • the plant includes in the basic version a rinsing tank or tank, a circulation pump, at least one non-return and another pressure-holding valve, and preferably a compressed air supply and a filter installed in the circulation circuit.
  • the system is mounted on a mobile platform.
  • the rinsing tubes can be rolled up on castors with retraction.
  • the system can be equipped with a simple dosing system, which consists of a Venturi pump, a Conductivity and / or pH measurement and a connected cleaning concentrate can be extended.
  • the tank is filled with a rinsing liquid consisting of a carrier liquid, e.g. Water and a proportioned rinse or preservative concentrate is filled.
  • a carrier liquid e.g. Water
  • a proportioned rinse or preservative concentrate is filled.
  • air can be introduced into the cleaning circuit in a continuous or pulsed manner for the dissolution of crystalline residues in the fluid system.
  • thermal support of the cleaning process by a heater.
  • the spent rinsing liquid can be conveyed by the introduced air from the fluid system and the connected lines back into the tank to use them again by means of a treatment system, or to promote in a treatment tank or simply discard it in a drain.
  • the plant is advantageously combined with both a water treatment plant, as well as with a plant for the treatment of spent rinse liquid.
  • the system of the invention is easy to use and hygienic.
  • the flexible connections can be plugged after cleaning to a parking station.
  • FIG. 1 shows a fully equipped cleaning system, which is connected via the connection (1), the water inlet valve (2) and the flow meter or water meter (3) to a water supply or not shown here water treatment system.
  • the conditioning filter (32) with its components is shown as a possible option for clarity.
  • the supplied liquid flows into the washing container (4) until the flow meter (3) or also the level sensors (5) signal the end of the feed.
  • circulation pump (9) By means of circulation pump (9), the liquid is conveyed through the flushing line (8), which has two line sections (8a) and (8b).
  • the circulation pump (9) can be used both air and electrically operated. Before starting the cleaning of the fluid system (20), all connections of the system can be physically or chemically cleaned. This is possible both via the heater (11) and via an ozone cell or flushing concentrate (29), not shown here.
  • valve (31) is closed, the pressure-controlled air supply (17) opened and briefly put pressure on the compounds. If the valve (10) is not a check valve - as is preferred - but a normal shut-off valve, this is also closed. If the pressure drop monitored by the pressure measurement (16) remains within a specified limit, the connections are considered tight.
  • the pressure holding test can also be carried out with liquid. For this is filled tank (4) the Pump (9) started briefly, the valve (31) remains closed. The pressure holding test is monitored by means of pressure measurement (16).
  • the desired amount of liquid is supplied to the tank (4) either via the lid (7) or the downstream flushing hose (19) until the mark at marking (42) is reached. Thereafter, the rinsing concentrate is added manually.
  • the dosing of the rinsing concentrate takes place in a system with dosing system via a venturi pump (24) and the opened concentrate valve (25).
  • the aspiration process is monitored by conductivity and / or pH measurement and is terminated when a predetermined concentration has been reached.
  • the flushing hoses (19) with the couplings (28) are coupled to the connections of the fluid system (20).
  • the rinsing tubes (19) are rolled up on rollers with retraction (45) and are pulled out of the rinsing system for connection or automatically rolled up after use and, if necessary, put on the parking station (18).
  • the pump (9) circulates the rinsing liquid out of the container (4) via the fluid system (20), the filter (21) into the rinsing line (8). Detached particles remain in the filter (21) and must be rinsed cyclically by means of a filter rinse valve (22).
  • the check valve (15) can be opened manually for this purpose.
  • the rinsing liquid can be emptied via the drain valve (14) or, if the treatment filter (32) is present, partially supplied to a regeneration tank.
  • the liquid is displaced from the fluid system (20) and the lines (19) by means of air.
  • a preservation with the preservation concentrate (27) can be carried out after cleaning and emptying of the container (4). This process is identical to the rinsing process. Both the cleaning concentrate (29) and the preservation concentrate container (27) can be provided with a fill level monitor (30).
  • the water meters (2/37) can be used to verify the fluid balance.
  • FIG. 2 shows, use highly pure, residue-free liquid as a carrier liquid.
  • the rinsing system is preferably connected to the connection (1) to a reverse osmosis.
  • additional treatment steps after reverse osmosis such as electrodeionization and / or additional filter stages.
  • the high-purity rinsing liquid is conveyed in this application to the cleaning material introduced into a high-purity fluid chamber (43).
  • the supply of the cleaning fluid takes place via a sterile filter (38) whose functionality is tested by supplying air into the primary circuit (38a).
  • the treatment of the rinsing liquid preferably takes place by means of a dosing system according to the procedure already described FIG. 1 ,
