Plasma micro reactor apparatus, sterilisation unit and analyser

摘要

Apparatus 10 for the production of a product gas such as hydrogen or ozone, comprises a supply 14 of reactant gas, a pair of electrodes 24 with a space 28 between them of less than 1 mm, a conduit 22 to lead the reactant gas from the source through the space 28 between the electrodes 24, a power source 26 to apply a voltage across the electrodes to dissociate the reactant gas and ultimately permit formation of product gas and a conduit 30 to supply the product gas to an outlet. Embodied uses include converting oxygen to ozone or steam to oxygen and hydrogen. A sterilisation unit for water treatment employs such apparatus and includes a fluidic oscillator to oscillate the flow of oxygen and/or ozone, with the outlet comprising a plurality of orifices submerged in the water for the purpose of forming micro bubbles of ozone. An analyser for detecting large organic molecules in e.g. air can employ the ozone generator to breakdown the large molecule into simpler and easier-to-detect-and-identify molecules.
