ELECTROSTATIC DEVICE FOR EMISSION OF IONIZED AIR Russian patent published in 2005 - IPC

FIELD: electrostatic devices of ionic emission.

SUBSTANCE: the invention is pertaining to the electrostatic device of ionic emission for deposition on a surface of the set of aerosol particles of the same class diameter inside the fluid medium of the quasihomogeneous quantities of ions. The device contains a conductive corona-forming electrode and a conductive nonecorona-forming receiving electrode. The pseudo-planar active surface of the receiving electrode is coated by a set of a quasiuniformly distributed craters having on their end areas a part of surface with the minimum radius of curvature and the embracing the holes protruding outside from the active surface in its both geometrical directions. A surface flow of ions coming out of the corona-forming electrode in a direction to the active surface of the receiving electrode ensures the heightened homogeneity. The receiving electrode is preferably made with the help of lattice composed of metallic ribs.

EFFECT: the invention ensures the heightened homogeneity of the surface flow of ions coming out of the corona-forming electrode in a direction to the active surface of the receiving electrode.
