Definitions

  • This impregnation is to purge the air contained in the open cells of the structure spongy balls in order to give these balls a apparent density very close to that of water: if the air in the balls was not purged, the balls would be lighter than water and they would tend to float and clean only the upper part of the generally horizontal tubes of the condenser or the like.
  • the impregnation of the balls is most often done manually by kneading the balls under water before their injection into the closed cleaning circuit including the tubes to be cleaned.
  • a device for impregnating sponge balls intended for cleaning the tubes of a condenser or the like comprising an interposed reservoir between first and second associated valves respectively to a water intake pipe and to a water evacuation pipe, a fitting fitted with a third valve connecting the top of the tank to a source of new cleaning balls, a mesh grid too small to pass the balls arranged at inside the tank so as to reserve at the top of this one a room inaccessible to the balls, a pipe equipped with a fourth valve connecting said chamber to a evacuation and a device capable of generating a depression in this room, this generating device of vacuum being a vacuum pump.
  • the invention relates generally to installations cleaning tubes above defined and more particularly, but not exclusively, the processes and water impregnation devices for cleaning balls used by these facilities.
  • the device for impregnating sponge balls intended for cleaning the tubes of a condenser or the like comprises a reservoir interposed between a first and a second valves associated respectively with a pipe water intake and a water evacuation pipe, a fitting with a third valve connecting the top from the tank to a source of new cleaning balls, a mesh grid too small to let the balls arranged inside the tank so that reserve a room at the top of this room inaccessible to balls, a pipe fitted with a fourth valve connecting said chamber to an evacuation and a clean device to cause depression in this room, and it's essentially characterized in that the device vacuum generator consists of a cylinder piston with one of the two compartments separated by the piston communicates with the chamber in such a way that each piston goes back and forth successively generates an increase of a quantity well determined from the volume defined by the interior of the tank and through the spaces that communicate with this interior, when the above four serving valves of the tank are closed and then a cancellation of this increase.
  • impregnation processes implementing the above devices they are characterized according to the invention by the following steps: the first two valves being closed and the other two open, we introduce in the tank a load of new balls through the third valve; then, the second and the third valves being closed and the other two open, we admit water in the tank until full in water; then, all of the four valves being closed, the piston is actuated in the direction which corresponds to an increase in the volume in communication with the inside of the tank, which subjects this volume to a depression by emptying at least partially the balls of air they contain, air that is collected in the upper chamber of the tank and the capacity that communicates with this room; after what the first and fourth valves are opened so that refill all the volumes considered with water, which impregnates the balls at least partially with water emptied of air and the piston or the like is actuated in the direction reverse of the previous one to put it back in its position initial, the cycle of the two steps defined above which operate the piston back and forth can be renewed one or more times.
  • the invention includes, apart from these arrangements main, certain other provisions which preferably used at the same time and which will be more explicitly question below.
  • FIGS 1 to 3 of these drawings show schematically a device, established in accordance with the invention, allowing water balls to be impregnated cleaning, this device being mounted in respectively three different operating phases.
  • Figure 4 schematically shows an installation cleaning balls equipped with such a device.
  • Figure 5 shows schematically, on the one hand, a preferred construction method proposed in accordance with the invention for the impregnation device and, on the other share, the preferred association of this device with other accessories known per se.
  • the balls 1 to be impregnated with water are balls spongy rubber with open porosity.
  • the device shown in Figures 1 to 3 includes a tank 2 served near its base by a water inlet pipe 3 fitted with a first valve 4 and, near its top, by a pipe water outlet 5 fitted with a second valve 6.
  • the top of the tank 2 is connected, through a third valve 7, to a hopper 8 for receiving balls 1 new.
  • tank 2 The upper portion of tank 2 is crossed by a horizontal grid 9 which delimits above it an enclosure 10.
  • This enclosure is itself crossed by a vertical corridor delimited laterally by a grid cylindrical 11 connecting the hopper connection 8, fitted with valve 7 with the inside of the tank 2.
  • the meshes of the mesh elements 9 and 11 are small enough that they cannot be crossed by balls 1 and large enough so that none only negligible pressure drop is suffered by water as it passes through these meshes.
  • a float 12 constituted for example by a hollow ball filled with air, is arranged, in a structure light guide 13 constituted in particular by metal rods, just below the mouth bottom of the screened corridor 11 so that free this mouthpiece for its normal rest position illustrated in Figure 1 and instead close this mouthpiece for its high position shown on the Figures 2 and 3.
  • This sealing prevents any rise of balls in lane 11 during the impregnation process in water, balls whose impregnation with water could then be compromised.
  • Enclosure 10 is atmospheric or more precisely to an evacuation pipe, by a pipe 14 fitted with a fourth valve 15.
  • a jack 17 comprising here a cylinder 18 and a piston 19 with rod 20 is put in communication with the tank 2 as follows: one A of the two chambers A and B, of cylinder 18, separated by the piston 19, is directly connected to the portion of the pipeline 14 which is located between the tank 2 and the valve 15.
  • tank 2 is empty in this sense that it contains neither water nor ball, and the valves 4, 6 and 23 are closed.
  • the higher level of the ball load as well introduced must not exceed, inside the tank 2, that of the base of the float 12.
  • valve 4 is opened, which admits a new volume of water inside tank 2, volume which permeates the balls 1 at least partially emptied of their initial air.
  • valve 15 is opened to expel the air from the circuit and make possible a full refill water capacities.
  • the impregnation of the balls in water is incomplete if the cylinder capacity, i.e. the volume of air or water displaceable in chamber A when of each complete back-and-forth movement of the piston 19, is insufficient, relative to the volume of water with which one wishes to impregnate balls.
  • the impregnation of these balls may require more than two successive cycles.
  • the number of cycles required can be determined as follows.
  • the pressure P is less than 0.2 bar so that the balls are sufficiently impregnated, that is to say that their apparent density is sufficiently close to that of the water.
  • agitating means can be provided in or on hopper 8 to ensure that the balls descend by simple gravity into the airlock 26 upon opening the upper drawer 24, which opening can be controlled by closing the lower drawer 25.
  • Figure 5 shows in its right part another construction of the above impregnating device described.
  • the structure 13 for supporting and guiding the float 12 is here supported by a grid 16 which crosses the interior of tank 2 a little above the membrane 29.
  • This grid 16 like grid 9, is arranged so that it cannot be crossed by the balls.
  • the tubes 38 in question which form a bundle horizontal, are supplied with cold water from a line 39 and the heated water coming out of these tubes is evacuated through a pipe 40.
  • This pipe 40 is equipped with a device to grids 41 for collecting the cleaning balls and the recycling piping 37 is itself fitted with a circulation pump 42, an airlock 43 used to collect the balls when we want to stop their circulation, then, at its downstream end, an injection nozzle 44 of the balls opening into the intake pipe 39.
  • valve 4 allowing water to enter the device impregnator as well as the outlet pipe 5 of this device and that its loading hopper 8 associated with the corresponding valve 7.
  • the impregnating device above is further associated with a sorter of balls of the type which is the subject of document US-A-4 974 662 as well as a ball counter like those currently known.
  • the assembly thus formed ensures a fully automatic operation of the cleaning considered.
  • the sorter covered by the above patent allows permanently remove used balls from the circuit, the diameter has become too small.
  • the ball counter As for the ball counter, it measures continuously the number of balls remaining in circulation: when this number of balls becomes insufficient for ensure effective cleaning, i.e. when the number of missing balls reaches a preset threshold, said counter emits a signal indicating that a charge of new balls must be reinjected into the circuit cleaning.
  • the impregnation device described above is sized according to the desired importance for this load of new balls and it allows to reinject this load in the circuit as soon as the counter gives it the signal.
  • the ball counter mounted on the recycling 37 is designated by reference 45.
  • Sorter 46 is mounted on the same pipe just downstream of counter 45.
  • Worn balls whose diameter has become too large small are diverted by a line 47 towards a collector of worn balls 48 whose base, in the shape of a truncated cone or the like, communicates with a valve 49 for draining worn balls.
  • the manifold 48 is connected to the pipe water inlet 3 above, fitted with valve 4.
  • a grid 50 mounted in this collector prevents that the used balls can have access to this line 3.
  • a gate valve 51 mounted on said pipe 3 makes it possible to fine-tune the selection made by sorter 46.
  • the assembly is then ready to accomplish again following the above operations which automatically allow to evacuate a given load of used balls and to introduce an equivalent load of new balls after impregnate them with water.
  • This device has significant advantages by compared to those previously known and in particular the following.
  • This hopper can be significant, filling it into balls does not require only two or three interventions per year, which represents a significant labor saving by compared to current installations for which impregnation of the balls to be injected must be carried out manually several times a month.
  • the possible automation of the whole of the installation allows the cleaning of the condenser or the like a high degree of safety since, with this installation, we are sure that the balls in circulation ensuring cleaning are at all times, on the one hand, in sufficient number, and on the other hand, in a low wear condition for which cleaning efficiency is high.
