Definitions

  • the invention relates to precipitation tube bundles for wet electrostatic precipitators, especially for the separation of sulfur oxides and dust from exhaust gases.
  • filters consist of a Bundle of plastic pipes connected to their walls.
  • an electrode in the middle of each tube.
  • the inner walls of the tubes are covered with a flowing, electrically conductive washing liquid, and between the electrode and the wall of the tube strong electric field is formed. This does one Ionization of the exhaust gases so that they are electrically charged and following the electric field lines to the pipe walls hike.
  • There the loaded exhaust gas particles from of the washing liquid and after the pipe ends transported outside. To avoid electrical Breakdowns are grounded to the pipes.
  • the invention is based on the object Rain tube bundle for wet electrostatic precipitators available to be provided, the individual tubes being interchangeable, low-tension and can be held very dimensionally.
  • the invention is based on the basic idea one-piece tubes through an upper sleeve and one lower guide ring and if necessary with a middle one To hold the guide ring in a positive fit.
  • the individual pipes are connected by one another Half pipe elements held.
  • the tube bundle can be hung in a housing.
  • the lower guide ring is used to keep the Pipes and for connecting the pipe ground to the outside.
  • the middle one Guide ring is used to keep the pipes spaced greater length of the tube bundle.
  • the invention has the following advantages.
  • Pipe bundles can be made from different Materials are manufactured, e.g. the supporting structure made of a different material than the rain pipes.
  • the precipitation tube bundles have separate ones Pipe walls so that e.g. in case of voltage flashovers only the pipe in question is damaged.
  • the rain pipes can be exchanged without problems if damaged become.
  • Different types of earthing can be used can be easily installed in the rain tube bundle. The earthing can be prefabricated and simple in the event of damage be replaced or repaired.
  • the rain tube bundle can be made easier and cheaper become. Opposite bundles of composite half-pipe elements there are no gaps or abutting edges in the invention.
  • the precipitation tube bundle 1 is a precipitation tube bundle 1 over a Suspension flange 6 suspended in a housing 7 on a projection 8.
  • the smoke gases to be filtered penetrate the pipes 2 in the axial direction parallel to the plane of the drawing.
  • the Pipes 2 are in their upper part by an upper one Support sleeve 3 held rigidly with the support flange 6 connected is.
  • the precipitation tube bundle 1 a middle guide ring for the spacing the tubes 2 is provided. At the bottom it shows Rain tube bundle a lower guide ring 5.
  • the lower guide ring 5 is used to keep the distance Pipes 2 and for connecting the pipe ground to the outside.
  • the single ones Pipes 2 have spot welding or at the pipe ends Shear welds that also penetrate the pipe wall can to the pipes in the sleeve or the guide rings secure against axial displacement.
  • the Cuff 3 and the guide rings 4 and 5 hold the Pipes in a positive fit.
  • the support flange 6 and the upper sleeve 3 welded.
  • Each tube 2 of the Rain tube bundle 1 has an upper ground as internal Grounding and a lower grounding on that in the surface of the pipe is welded and with the lower guide ring 5 is connected.
  • the earthing of the individual tubes 2 are electrically connected to each other.
  • Fig. 2 shows a cross section along the line A-A through the upper support sleeve 3 in Fig. 1.
  • the individual tubes are supported by interconnected half-pipe elements 3a.
  • the half-pipe elements 3a are preferably injection molded made of polypropylene.
  • the rain pipes 2 are preferably made of polypropylene in the extrusion process or polyvinyl chloride, or a conductive and / or flame retardant thermoplastics, the Inner pipe wall preferably for roughening and therefore better Wetting the surface is sandblasted.
  • Fig. 3 shows a cross section along the line B-B in Figure 1. It can be seen that the tubes 2 in the areas outside the upper cuff and the middle and lower guide rings are arranged without contact. On this can compensate for any tensions that may occur and there is a free space for the exchange z. B. defective pipes 2.
  • the upper sleeve 3 in the axial direction a length of 900 mm and the middle and lower guide rings 4, 5 each have a length of 300 mm.
  • the bottom ground of each tube is there preferably from a carbon cord or carbon tube.
  • the embodiment of the invention shown in the drawings consists of one-piece round tubes with a circular cross section.
  • the rain tube bundle can but also from one-piece honeycomb tubes with a hexagonal Cross section exist.
