ELECTROSTATIC INJECTOR Russian patent published in 2012 - IPC F24F3/16 

FIELD: ventilation.

SUBSTANCE: electrostatic injector comprises housing with inlet confuser and constant cross-section channel, discharge electrode, collecting electrode, which are connected to high-voltage DC supply and installed in parallel planes perpendicular to longitudinal axis of constant cross-section channel; injector outlet is made in the form of diffuser, the small cross section of which is adjacent to constant cross-section channel, and in diffuser outlet section there installed is grid with regular non-uniformity, to the inner surface of which a catalyst is applied, and guide plates are installed in inner cavity of diffuser, which are uniformly distributed between diffuser walls; at that, surface of the above plates is rough and a catalyst is applied to them.

EFFECT: invention allows controlling ozone concentration at electrostatic injector outlet; and at the same time, high efficiency coefficient and relatively low cost of injector is provided due to its easy manufacture.
