Abstract:
A modular corona discharge reactor for the processing of gaseous media, comprising an inlet duct and an outlet duct, characterised by the features in combination comprising a plurality of vertically mounted corona discharge reactor chambers positioned between the inlet and outlet ducts and communicating therewith, each corona discharge reactor having a cylindrical outer electrode structure and an axial inner electrode structure, a high voltage pulse power supply positioned in vertical alignment with the inner electrode of the reactor chamber and connected directly thereto, each high voltage pulse power supply being adapted to produce voltage pulses of a magnitude sufficient to excite a corona discharge in a gaseous medium to be processed as it passes through the associated reactor chamber, means for balancing the flow through the reactor chambers of the gaseous medium to be processed, a low voltage power supply connected to each high voltage pulse power supply and a control unit for controlling the action of the low voltage power supply to cause the high voltage pulse power supply to apply high voltage pulses to the corona discharge reactor chambers with a pre-determined temporal relationship.
