Effect of Particle Layer Condition on Characteristics of Fluidized Bed Type Ozone Generator Using Atmospheric Pressure Discharge Plasma

摘要

Ozone is almost exclusively generated by dielectric barrier discharges. Its main characteristic is the presence of a dielectric layer between the discharge gap and at least one of the electrodes. The presence of the dielectric layer leads to the formation of a large number of micro-discharges of nanosecond duration, and this discharge forms nonequilibrium plasma in atmospheric pressure. In this study, fluidized bed type reaction field was formed by installing fluidized bed in a traditional ozonizer. This method realizes the expansion of plasma chemical reaction field and the acceleration of equalizing of the ozone concentration in the ozonizer. As a result, fluidized bed (particle layer) condition for efficient ozone generation have been clarified.
