Definitions

  • the invention relates to an electrical separator with honeycomb-shaped precipitation electrodes.
  • DE-PS 26 41 114 describes a method for producing a plastic electrostatic filter in a honeycomb form by joining together hot-pressed plate strips, which are made of glass fiber-reinforced polyester and have a cross-section, the individual plate strips being provided with flanges that extend over the entire length of the honeycomb bundle.
  • the plate strips are either glued together or, if they consist of a thermoplastic material, connected to one another by welding.
  • the invention has for its object to provide an electrical separator with honeycomb-shaped precipitation electrodes, in which the individual components are connected to one another in a simple manner, so that the number of honeycomb-arranged precipitation electrodes can be adapted relatively quickly and easily to fluctuating exhaust gas quantities or pollutant concentrations.
  • the object on which the invention is based is achieved by an electrostatic precipitator with honeycomb-shaped precipitation electrodes which consist of star-shaped elements, each star-shaped element consisting of three wall parts which are connected to one another in the center and are each arranged at an angle of 120 ° to one another, each on the outer edges Wall portion is arranged in the longitudinal direction at least one pipe section, the pipe sections of two adjacent, star-shaped elements are each arranged one above the other and the individual star-shaped elements are connected to one another by a connecting rod, which is arranged in the pipe sections of at least two adjacent star-shaped elements.
  • the term "pipe section” is to be understood as a piece of a pipe which gives the connecting rod adequate guidance and has a length of 5 to 50 cm.
  • the star-shaped elements are made of electrically conductive materials such as steel or lead.
  • the individual pipe sections are connected, for example by welding or gluing, to the respective outer edges of each wall part. It has surprisingly been found that the electro-separator according to the invention can be adapted relatively easily to fluctuating amounts of exhaust gas, the existing separating surface of the precipitation electrodes being able to be fully utilized, since both surfaces of the three wall parts of a star-shaped element which are connected to one another are used as the separating surface can be. If, for example, an increase in the amount of exhaust gas is to be expected, the existing grid of the honeycomb-shaped precipitation electrodes can be enlarged relatively quickly in a simple manner by arranging further star-shaped elements in a corresponding manner.
  • a preferred embodiment of the invention is that the star-shaped elements consist of an electrically conductive plastic. It is advantageous that the star-shaped elements can be produced as individual parts with the pipe sections arranged on the outer edges of each wall part in the longitudinal direction, joining methods such as welding or gluing for connecting the pipe sections to the respective wall part being no longer necessary.
  • FIG. 1 shows the top view of a star-shaped element which consists of three wall parts connected to one another in the center.
  • Fig. 2 shows the cross section of the honeycomb-shaped precipitation electrodes, which consist of the star-shaped elements.
  • FIG. 3 shows the top view of a connection point at which three star-shaped elements according to "A" in FIG. 2 are connected to one another.
  • FIG. 4 shows the side view of a connection point at which three star-shaped elements are connected to one another, according to section B-B in FIG. 3.
  • Fig. 1 the top view of a star-shaped element, which is formed from three centrally connected wall parts (1, 2, 3), is shown, the angle between two adjacent wall parts (1 and 2, 2 and 3, 3 and 1) is 120 °. At least one pipe section (1 ', 2', 3 ') is arranged in the longitudinal direction on the longitudinal edges of each wall part (1, 2, 3).
  • FIG. 2 the cross section through the honeycomb precipitation electrodes with the connecting rods (4) is shown schematically in a simplified manner.
  • the individual star-shaped elements are connected to one another with the connecting rods (4), the individual connecting rods (4) each being arranged in the tube sections of at least two adjacent star-shaped elements.
  • connection point at which three star-shaped elements are connected to one another via a connecting rod (4) is shown enlarged according to "A" in FIG. 2, the angle between two adjacent wall parts (2, 5, 6) in each case 120 ° is.
  • the outer edge of one wall part (2) is over a Welded connection (2 '') connected to the pipe section (2 ') in which the connecting rod (4) is arranged.
  • the pipe section (2 ') is above the pipe sections (5', 6 '), not shown in Fig. 3, which are each connected to the adjacent wall parts (5, 6) by a welded connection (5'',6'') , arranged.
  • the pipe section (2 ') has an outside diameter (a) of 10 to 40 mm and an inside diameter (b) of 5 to 35 mm.
  • the diameter (c) of the connecting rod (4) is 5 to 30 mm.
  • FIG. 4 shows the side view of the connection point according to section B-B in FIG. 3, the two wall parts (2, 5) being shown rotated into the plane of the drawing.
  • the pipe sections (2 ', 5', 6 ') are arranged one above the other and connected to the respective outer edge via a welded connection (2' ', 5' ').
  • the device according to the invention is not limited to the embodiments shown in FIGS. 1 to 4.
