Abstract:
The present invention offers an operation method of an ozonizer and an ozonizer apparatus to improve ozone gas purity and to achieve long and safety electrolysis operation in such manner that, during normal operation of the ozonizer, ozone gas is generated at the anode in the anode compartment and hydrogen gas is generated at the cathode in the cathode compartment; and only when the ozonizer is stopped and operation is switched to protective current operation during which minute electric current is supplied to protect said anode, oxygen-containing gas is supplied to said cathode compartment after electrolyte and hydrogen gas in said cathode compartment are all drained out, so that said cathode is made function as a gas electrode for oxygen reduction reaction, using said cathode as a reversible electrode with two functions as a gas generation electrode and a gas electrode, thereby during normal operation, ozone is generated efficiently, and during the protective current operation, when safety is a key issue, hydrogen gas is not generated at the cathode and mingling of hydrogen gas into ozone gas generated at the anode is prevented.
Abstract:
The Diffusive Plasma is for effective treatment of contaminated air and material processing. Air is purified and disinfected by passing through the diffusive plasma device which includes a reactor or a plurality of reactors arranged in parallel or series and is energized by a high voltage alternating current power supply. The diffuser, being electrically isolated, provides extra nucleation sites to initiate discharges. It serves to improve the generation of uniform and consistent plasma and to reduce the variation of discharge properties among the reactors. The addition of a diffuser, thereby, enhances the overall effectiveness of decomposing chemicals and destroying microbes to achieve high air treatment and material processing performance. The diffuser can be made of suitable filtering materials to additionally serve as a filter. By incorporating suitable catalytic materials with the diffuser, the reactor becomes a catalytic plasma reactor wherein the plasma environment provides enhanced catalytic functions. Effective plasma power deposition may be obtained by controlling the amplitude, waveform period and shape of the voltage applied to the electrodes of the reactor and hence the operation of the reactors with plasma discharged of selected conditions for optimizing the treatment and processing efficiency while minimizing the generation of unwanted bi-product gases. The present invention also relates to a method for effective air treatment and material processing.
