Definitions

  • the invention relates to electrostatic precipitators with tubular or plate-shaped precipitation electrodes and toothed spray electrodes arranged in the center.
  • GB-PS 840 853 discloses electrostatic precipitators with tubular precipitation electrodes and spray electrodes in the form of toothed strips. It is also known to use spray electrodes in the form of toothed strips which are twisted about their longitudinal axis (AT-PS 121 928). Another possibility of designing the spray electrodes is shown in DE-AS 1 201 816. Here, band-shaped spray electrodes with sawtooth-like spray tips are used, in which the spray tips of the band are bent opposite one another at a certain angle from the plane of the band and additionally have a further sharp-edged bend on the same side. Finally, from GB-A 968065 an electrostatic filter with tubular precipitation electrodes is known, in which precipitation electrodes provided with spray tips are arranged in the center.
  • the distance between the tips of the spray electrodes and the precipitation electrode is limited to a fixed value. At this fixed value, the ratio of the distance of the spray tips from the central axis of the tubular precipitation electrode to the distance of the central plane or central axis from the walls of the respective precipitation electrodes is in the range of 0.6-0.8.
  • the invention has for its object to further improve the separation performance of electrostatic filters with toothed spray electrodes.
  • This object is achieved according to the invention in that the ratio of the distance of the spray tips from the central axis in the case of tubular precipitation electrodes or the distance of the spray tips from the center plane between plate-shaped precipitation electrodes to the distance of the center plane or center axis from the walls of the respective precipitation electrodes is between 0.4 and 0. 6 lies.
  • electrostatic precipitators are reproducibly accessible by adhering to the range of the spacing ratio specified above can preferably be applied to electrostatic filters which contain toothed, band-shaped spray electrodes which are twisted around their central axis by rotation.
  • An alternative preferred embodiment of the electrostatic precipitators contains toothed band-shaped spray electrodes which have been formed into three-dimensional bodies by bending the teeth out of the band plane.
  • the inventive design feature, 0.4 & r / R 9 0.6, which determines the optimal separation behavior of the electrostatic precipitator, is independent of the absolute mass of the electrostatic precipitator and the cross-sectional geometry of tubular precipitation electrodes.
  • diagram 1 The effect of the distance ratio r / R on the separation efficiency (expressed by the quotient of the particle migration speed w and the maximum particle migration speed w max is shown in diagram 1 (page 7).
  • the values w / w max are plotted for tubular precipitation electrodes and various toothed spray electrodes (either made by twisting the toothed spray electrode band or bending the teeth from the band plane) were obtained.
  • the points entered are measured values; the curve drawn represents the compensation curve.
  • Example 2 In a tube electrostatic precipitator of the type described in Example 1, but with an inner tube diameter of 250 mm, the operation was carried out under the same specific conditions as in Example 1. The results are as follows: From these results it can be seen that the ratio r / R and not the distance of the tooth tips of the spray electrode from the central axis or the distance of the tooth tip of the spray electrode from the nearest precipitation electrode wall is the determining parameter for the relative rate of migration.
  • Example 2 The same electrodes as in Example 1 were used in a plate electrostatic precipitator with a plate spacing of 200 mm.
  • r the distance of the spray tip from the imaginary center plane between the two parallel plate electrodes
