  • a seal is provided between the filter body 12 and the rim 22 of this filtration member 13, formed by an angle iron 30, which, reported by one of its wings, its wing transverse to the axis of the assembly, on the filter body 12, by virtue of a fallen edge 31 thereof directed radially towards said axis, is engaged, by its other wing, its wing axially elongated in the rim 22 of the filter member 13, in the vicinity of it.
  • the joint thus formed is interrupted locally at the right of the suction member 14, the desired tightness then being ensured at this location by a lip 32, carried by the suction member 14.
  • the filter member 13 Between its rim 22 and its shaft 20, and, in practice, on the downstream side of its rays 23, the filter member 13 comprises, transversely, an element filter 35, generally in the form of a disc.
  • spokes 23 of this filtration member 13 partition in angular sectors the internal volume of its rim 22.
  • the volume internal to the rim 22 is fragmented transversely into a plurality of compartments.
  • the filter element 35 is itself fragmented into as many filter panels that there are compartments inside the rim 22, a filter panel for each of these compartments.
  • the shaft 20 of the filtration member 13 thus formed is duly profiled hydrodynamically on the downstream side, and engaged on the upstream side in the hub 21 which carries it, with interposition between it and the latter appropriate bearings, it is duly wedged axially on this hub 21.
  • the hub 21 is connected to the ferrule constituting the body of filter 1, on the one hand by radial arms, which extend at 120 ° two by two, and on the other hand by a box, which itself extends at 120 ° relative to the arms above, by itself constituting an arm for the hub 21, and which forms the suction member 14.
  • the box thus forming the suction member 14 extends substantially along a vertical, being directed downwards, and, in elevation, it has a contour in a triangle, thus extending along an angular sector of the filtration 13.
  • this box is connected to the discharge pipe 15 associated.
  • This discharge pipe 15 extends substantially radially, and, at its end, it usually presents a flange, for its own connection, via a valve 49, and by any line, to a source of suction specified below.
  • the box constituting the member suction 14 is substantially flush with the rim 22 and the spokes 23 of this filtration member 13, and its corresponding wall has an opening 48; the outline of this opening 48 is generally quadrangular, and it is elongated buttonhole substantially along a radius of the filter member 13.
  • the filter member 13 In service, the filter member 13 is normally stopped, and the valve 49 controlling the discharge pipe 15 is then closed.
  • Debris, detritus or elements conveyed by the treated flow are stopped by the filter element 35 of the filter member 13, and, more precisely, by the massive parts of it.
  • the organ of filtration 13 is rotated by the drive wheel 27, and, jointly, the valve 49 controlling the evacuation pipe 15 is open, so that the box constituting the suction member 14 is the object, from the suction source to which it is then connected, a flow of suction directed outwards, as shown by arrow F3 on the Figure 1, and that the portions of the filter element 35 of the filter member 13 successively concerned by this suction member 14 are the object, at their passage to the right of the opening 48 thereof, and as shown schematically by arrows F4 in FIG. 1, of a circulation against the current.
  • the pipe 10 is the pipe water inlet of the condenser 19, connected to its inlet manifold 24; the water then crosses the tubes 34 and, from the outlet manifold 33, joins the exit 16.
  • the filter 11 is washed against the current by the suction created. by a horn connected to the outlet pipe 16; the wash water is in this case caused by the condenser pressure drop, which is low, see very weak, a few meters of water column; debris is therefore transported downstream of the condenser and be released to the natural environment when cooling of the condenser is in open circuit, or recycled when the cooling is in closed circuit; in open circuit, rejection to the natural environment is less and less tolerated, and, in a closed circuit, the concentration of debris increases and ends by blocking the filters.
  • the invention provides for the periodic interception and discharge of debris thanks to a static device to compensate for the excess pressure drop at through the installation.
  • a collector 36 for washing water sends this water to a separator static debris 37;
  • this separator 37 is installed substantially vertically and centrally comprises a perforated strainer 46 passing through the body of the separator 37, for example of cylindrical shape; at its lower part, the body of the separator 37 has an axial outlet 47, therefore right inside the strainer 46, opening into the open air and controlled by a valve 40.
  • a container 38 for collecting debris such as a perforated basket for example.
  • the body of the separator 37 is provided with a outlet pipe 39 radial washing water connected to a hydro-ejector 50; of course, the water leaving line 39 is freed of debris.
  • the hydro-ejector 50 includes an elbow inlet 52 whose external wall is crossed by an ejector 51 whose end external is connected to the outlet of a pump 42 and the internal end of which is of frustoconical shape, the small base of the truncated cone being at the end of the ejector; this small base is in the transverse plane of connection of a converge 53 and divergent 54; the divergent 54 is extended according to a pipe 55 whose diameter is equal to that of the inlet of the elbow 52 connected to the pipe 39 for water outlet without debris; line 55 is connected to the outlet pipe 16 of the condenser 19.
  • the suction of the pump 42 is connected to the pipe 55.
  • the separator 37 and the debris-free water outlet pipe 39 are connected by a pipe 41 for the re-supply of water to the separator 37.
  • the strainer 46 is very long so that the component of radial speed is low compared to the axial component: therefore, debris are pushed to the bottom of the strainer which is therefore self-cleaning.
  • a vent 44 is provided at the top of the separator 37.
  • the debris recovery installation can be common to multiple filters.
  • the affected filter is backwashed by opening its valve 49 and actuation of the rotation of the filter.
  • the pump 42 is put into service; the ejector 51 increases the flow of the washing water cleared of its debris by the separator 37.
