A hybrid discharge type ozonizer, which is superposed silent and surface discharges, has been designed and manufactured to apply for Nitrogen Oxides(NO) gas removal. The ozonizer consists of three electrodes, and is classified three types of ozonizer by changing applied voltage. Investigation was carried out variance with the flow rate of supplied oxygen gas, discharge power and the sorts of superposed discharge type ozonizer. Moreover, NO(1200[ppm])/$N_2$ gas removal investigation was also conducted to apply for environment improvement field. Two kinds of NO gas removal investigations were conducted. It distinguishes the investigations into NO gas reaction method. According to these studies, maximum removal rate of 100[%] in NO gas was obtained, and 8334[ppm] and 3249[mg/h] of maximum ozone concentration and generation were also obtained respectively.

In this paper, a co-axial cylinder type ozonizer using silent discharge applying radio frequency voltage known as an ozone generation was designed and fabricated. A cooling system was installed to investigate the characteristics of ozone generation in accordance with temperature change of the supplied gas known as an important factor. The characteristics of ozone generation were investigated in accordance with the change of cooling temperature.

산업현장에서 용매, 세정제로 다량 사용되고 있는 휘발성 유기화합물들은 함유하고 있는 유해한 독성 때문에 그 처리에 관심이 집중되고 있으며 이 중 촉매산화법은 1990년대 들어 새로운 VOCs처리기술로서 이산화티타늄과 같은 금속산화물의 광촉매를 사용하는 공정이 활발히 연구되고 있다. TiO$_2$를 광촉매로 이용한 광촉매산화법은 아주 작은 에너지로서 2차적인 부산물없이 VOCs를 완전히 분해시킬 수 있고 태양광의 자외선을 에너지원으로 이용할 수 있는 장점 때문에 장래의 경제적인 처리기술로서 각광을 받는 기술이다.(중략)

In this paper, an analogical method for measuring the electrical characteristics of the silent discharge in the Na2CO3 electrolyte is proposed by using an electrical equivalent model which consist of charging and discharging circuits. The electrical equivalent model is constructed with the use of zener diode and capacitor, and the electrical characteristics can be obtained by the voltage and charge traces which appear a simple parallelogram on the oscilloscope. The area enclosed by the parallelogram could be considered of the energy input per cycle, and is independent of the applied voltage waveform but dependent on the maximum applied voltage.

A multilevel inverter employing a cascade transformer is proposed for a silent-discharge-tube ozone generating system. The proposed inverter consists of four full-bridge inverters and fourteen transformers which have a series-connected secondary. It can accurately control the amplitude of the output voltage; hereby, it improves a linear characteristic of the rate of ozone yielding. The power regulation characteristics and operational principle of the proposed system are explained from a practical point of view. High precision ozone generating performance of the proposed multilevel inverter is verified by computer-aided simulations and experiment results.
