Evaluation of Novel Integrated Dielectric Barrier Discharge Plasma as Ozone Generator

Abstract

<p>This paper presents a characterization of an integrated ozone generator constructed by seven of reactors of Dielectric Barrier Discharge Plasma (DBDP). DBDP a has spiral-cylindrical configuration. Silence plasma produced ozone inside the DBDP reactor was generated by AC-HV with voltage up to 25 kV and maximum frequency of 23 kHz. As a source of ozone, dry air was pumped into the generator and controlled by valves system and a flowmeter. We found ozone concentration increased with the applied voltage, but in contrary, the concentration decreased with the flow rate of dry air. It was also found that a maximum concentration was 20 mg/L and ozone capacity of 48 g/h with an input power of 1.4 kW. Moreover, in this generator, IP efficiency of 8.13 g/kWh was obtained at input power 0.45 kW and air flow rate of 9 L/min. Therefore, be the higher ozone capacity can be produced with higher input power; however, it provided lower IP efficiency. The effect of dry air flow rate and applied voltage on ozone concentrations have been studied. At last, spiral wire copper was very corrosive done to the interaction with ozone, and it is necessary to do a research for finding the best metals as an active electrode inside of the quartz dielectric.

Study of Energy Saving for Fish Preservation by Refrigeration SystemBased on Ozone Technology

“…shelf 1, 2, 3, and freezing compartment for 30 minutes every day.Ozone concentration applicatedinside of fish storage system by ozone technology in refrigerator ( Fig.1) can be determinated. The concentration of ozone in the refrigerator is the ozone concentration generated by the generator multiplied by the flowrate and divided by the volume of the refrigerator [14]. In this study we used ozone concentraion inside refrigerator was 6 mg/L.…”

“…Previous research has been done on the red tilapia, which represents white-fleshed fish, in the refrigerator where ozone was delivered with a concentration of 0.5-45 ppm. The TVBN test results showed that fish on each shelf in the refrigerator with ozone treatment still meet Indonesian NationalStandard (INS) [14,15], until the 16th day. In contrast, fish placed on refrigerators with no ozone treatment have an untoleratedtvbn value on the 8th day.…”

Low-Cost Automotive Capacitive Discharge Ignition (CDI) Coil for Low Frequency Ozone Generator

“…From the calculation on equation 1- (4), it can be determined that the ignition coil amplifying factor is 196.71. This result is then used to determine output voltage on the coil's secondary windings.…”

“…Although ozone can be produced naturally, it can be generated artificially through various ozonizer methods for the industrial purpose such as corona discharge/dielectric barrier discharge, UV-based ionization, and electrolysis [2]- [6]. Corona discharge or dielectric barrier discharge method is more costeffective than other methods [2]- [4]. The air ionization process is started when oxygen molecules give and get electrons.…”

“…Most ozone generating methods require high voltage power supply since it is mandatory to generate corona for the ozonizer process [4] [7] [8]. However, a high voltage power supply, especially its transformers, are quite complex and costly.…”
