Abstract:
A high efficiency plasma processing system for use in the generation of large quantities of gases, particularly hydrogen peroxide or ozone, for chemical commercial and industrial applications is based upon a homogeneous electrical glow discharge. In addition to the homogenous discharge, the high efficiency of ozone or other chemical production is achieved by exciting the discharge with high voltage pulses which have a voltage rate-of-rise in excess of 500 V/ns and incorporating an internal gas circulation system which maintains the temperature of the process gas to a level where the thermal decomposition of ozone, for example, is significantly reduced. A homogeneous and stable atmospheric glow discharge is developed by preionizing the discharge region with ultra-violet radiation, for example, immediately before the application of the main high voltage pulse across the electrodes of the discharge cell.
Abstract:
A corona discharge generating device includes a housing having a bottom wall and a side wall made of conductive material adapted to be electrically connected to a negative high-voltage pulse generator. A ferrofluid layer is provided inside the housing, on the bottom wall. An insulating sheet is provided inside the housing, over the ferrofluid layer, for supporting a layer of electrolyte liquid. A discharge electrode is placed at a predetermined distance over the layer of electrolyte liquid, and adapted to be connected at a positive high-voltage. A magnet is provided for inducing a magnetic field on the ferrofluid layer, so as to form magnetically induced cones on the surface of the ferrofluid layer, in order to enhance formation of Taylor cones on the surface of the electrolyte liquid, when the negative high-voltage pulse is applied on the housing.
