Influence of Parameters of Water Movement at Its Treatments on Energy Efficiency Pulse Barrier Discharge

Abstract

A study of the energy efficiency of the pulsed barrier discharge during water treatment in the aerosol state depending on the energy of the pulses (21-72 mJ), their repetition rate (50-300 Hz), the concentration of organic impurities in water (50-100 mg / l) and water content (1.6−3.2%) in the water-air mixture. The discharge was generated by unipolar short pulses (~ 100 ns) in an electrode system with vertically arranged cylindrical electrodes with a diameter of 2 mm, the distance between which was 2 mm. The highest energy yield, which was obtained by decomposing the impurity by 90%, was 32 g / kWh. In order to determine the influence of water movement parameters on the energy efficiency of a pulsed barrier discharge under similar conditions, the energy efficiency of this type of discharge during water movement in film, drip and aerosol states was compared. It is concluded that water treatment should be carried out in the drip state on the submillimeter size of the drops. In the case of such water movement, the energy efficiency of the pulsed barrier discharge is ≈30% higher than in aerosol. References 15, figures 6, table 1.
