Definitions

  • the present invention relates to electrodes generally and, more particularly, but not by way of limitation, to a novel mixing electrode providing effective charge transfer at high fluid flow rates.
  • Transferring an electrical charge to particulate contamination in a nonconducting fluid is problematic, particularly when the non-conducting fluid is moving at a relatively high flow rate.
  • a device for transferring charge to contaminant particles in a contaminated fluid comprising: a charge electrode for insertion in a non-conducting conduit, said charge electrode being in the shape of a static mixer.
  • Figure 1 is a side elevational view, in cross-section, of the present invention.
  • Figure 2 is an end elevational view of the invention.
  • FIGS 1 and 2 illustrate an electrode 10, bearing a charge voltage, and inserted in a insulating fluid conductor, or pipe, 12.
  • Electrode 10 is in the shape of a static mixer. By passing a contaminated fluid through conductor 12 at a rate of roughly one meter/second, the flow rate near the sharp edges of electrode 10, which function as charge transfer surfaces to the particulate contamination, is much greater than two meters/second.
  • Charge transfer is still effective for contamination levels greater than about 10 "9 wt/wt.
  • Contaminate particle size may be in the range of from about 0.05 to about 100 microns diameter.
  • Charge voltage is preferably greater than or equal to about +/- 5kN.
  • Preferred materials for electrode 10 are stainless steels, titanium, hastelloy, and platinum.
