Definitions

  • the invention relates to the use of sheets of conventional structural steel clad on both sides with corrosion-resistant steel for the production of spray and precipitation electrodes for dry-working electrostatic filters in which pyrophoric dusts are separated.
  • the spray electrodes would stretch longer than the frames under operating temperature.
  • the electrodes would then no longer be arranged in the middle between two precipitation electrodes, but could perform uncontrolled movements in the gas flow, which would result in the distance to the precipitation electrodes, thus reducing the applicable operating voltage and ultimately also the separation performance.
  • a design of the spray electrodes and the clamping frame made of the same scale-resistant material is only considered for special cases for price reasons.
  • scaling-resistant materials are difficult to process, so that higher costs can also be expected for production and assembly.
  • the clad sheets can be processed almost as easily as you are used to with conventional structural steels. Although they are about 50% more expensive, this is not significant in terms of the benefits that can be achieved.
