Description:

Gliding arc discharges have been investigated as a potential technology for gas phase pollution treatment and for liquid phase pollution treatment. Ultimately, the practical use of gliding arc technology to promote chemical transformations, such as the removal of organic pollutants in water or the generation of hydrogen peroxide, other reactive oxygen species, or reactive nitrogen species for treatment of potentially contaminated foods, depends on the efficiency that can be achieved.

The present invention describes a plasma gliding arc discharge reactor that is useful for chemical transformations in liquids and gases. The reactor may include a housing having a plurality of divergent electrodes, a power supply connected to the electrodes delivering pulsed power to the reactor, and a nozzle that directs a mixture of a carrier gas and a liquid to a region between the divergent electrodes, thereby generating plasma in the region. The nozzle can include a first inlet for receiving the carrier gas, a second inlet for receiving the liquid and a mixing chamber that is configured to mix the carrier gas and the liquid prior to being directed to the region.
