Definitions

  • the invention relates to a distribution arrangement and injection of sludge into the feed chute waste from a sludge and co-incineration furnace waste such as household waste, of the type comprising a collector in which the sludge is pushed by a pump and at least one sludge injector in the chute, installed on the collector, as well as filtration means located downstream of the pump to retain foreign bodies contained in the sludge.
  • the means of filtration are formed by a filter placed at the outlet of pump and thus being in the part of the circuit where the pressure is the strongest. This pressure is about 50 bars but can reach 100 bars or more. Therefore the filter is robust and large and thus heavy because it is mounted in the collector having a diameter greater than 100 mm, see 200 mm.
  • the object of the present invention is to provide a arrangement for the distribution and injection of sludge, type indicated above, which overcomes the disadvantages which have just been stated.
  • the injector is removably mounted in the manifold so that part of the injector is engaged in the collector and in that the means are incorporated in the injector part which is engaged in the collector.
  • the part rear of injector passes through manifold transversely passing through windows suitable in the side wall of the manifold while the front part of the injector opens into the feed chute.
  • the filtration means incorporated into the injector are made in the form of a slit or light made in the side wall of the injector part, which is engaged in the collector.
  • the collector is connected to the chute by a device cuff through which the front part of the the injector.
  • the injector can be removed by a withdrawal movement from the injector through the manifold.
  • the injector is fixed on the collector by a device quick disassembly.
  • the fixing device comprises, around the window passage of the injector, which is located on the side far from the chute a radially projecting cuff on which is removably attached by the device to quick disassembly of the rear end of the injector.
  • the injector has a flange at its rear end full radially protruding and a collapsible collar fast ensuring the fastening of the flange against the free front face of the cuff.
  • an extraction tab is fixed on the front face free from the flange.
  • the injector is provided with a guide ring and sealing to the right of the passage window of the injector, located on the side of the chute.
  • the sleeve for fixing the collector to the trunking consists of two integral parts respectively of the chute and collector and assembled by flanges provided at the free ends opposite the two parts.
  • Figure 1 is a schematic view illustrating the sludge distribution and injection arrangement according to the invention, in a co-incineration oven installation sludge and waste.
  • Figure 2 is a sectional view of the arrangement of distribution and injection of sludge according to the invention, indicated in 4 in Figure 1.
  • Figure 1 shows a co-incineration oven installation sludge and waste such as garbage housewives, which is equipped with a distribution arrangement and injection of sludge into the furnace, according to the present invention.
  • References 3, 1, 2 denote respectively the combustion chamber of the oven, a waste feed hopper and a chute which brings the waste poured into the hopper 1 into the room 3.
  • the arrangement of distribution and of sludge injection indicated in 4 is arranged so as to ability to inject sludge into the chute. This arrangement is shown in more detail in Figure 2.
  • the distribution arrangement and injection of sludge into the chute 2 including the jacket of water is indicated in 5 essentially comprises a collector 7 in which the sludge is pushed by a pump not shown and a number of injectors sludge 8 which is mounted on the collector and of which only one is shown.
  • the manifold 7 of circular cross section in the example shown is fixed to the chute 2 by through a tubular sleeve 9 made of two parts 10 and 11 respectively secured to the manifold 7 and chute 2 and assembled using flanges 12 and 13 at the ends opposite the two cuff parts.
  • the integral cuff part 10 of manifold 7 projects radially outward of it and is coaxial to a circular window 15 practiced in the collector wall.
  • the injector 8 is produced in the form of a tubular body the rear part 17 of which crosses diametrically the manifold 7 and the front part 18 of which is coaxial with the cuff 9 and opens in 19 in chute 2.
  • the injector goes through window 15 and through another window 21 also made in the cylindrical wall of the manifold 7, diametrically opposite the window 15.
  • the rear end 22 of the tubular body 17 of the injector, which projects radially from the manifold 7 outwards is closed by a full flange 23 which has a tab on its outer front face extraction 24.
  • the protruding part 22 is coaxially engaged in a support cuff 25 which is fixed on the outer face of the collector 7, surrounding the window 21.
  • the injector is fixed to the manifold 7 by means of a quick dismantling device, produced in the example shown as a quick release collar 27 which, in its fixing position, holds the flange full 23 in a position applied against the face front of the cuff 25.
  • a quick dismantling device produced in the example shown as a quick release collar 27 which, in its fixing position, holds the flange full 23 in a position applied against the face front of the cuff 25.
  • the cylindrical body 17 of the injector is provided with a guide ring and sealing 29 which is provided at the window 15.
  • the rear part 17 of the injector 8, which is engaged diametrically in the collector 7 is provided with one or more slots or axial light 30 which serves as a filter screen.
  • the length of the slot 30 is somewhat smaller than the diameter of the collector.
  • the pass area of the filter of each injector is large.
  • each injector has its own filter element formed by the slot (s) 30 and is easily removable by undo the quick-release collar 27 and then removing it from the manifold using tab 24.
  • each injector Since the weight of each injector is low, for example of the order of 5 kg, disassembly is easy.
  • the retention volume of foreign bodies is large since constituted by the collector which measures 200 mm in diameter and is 2 to 6 m long.
