Description
본 발명은 대면적 코로나 방전에 관한 것이다. 종래 기술에 의한 코로나 방전은 평행판 또는 Tip 방식의 전극을 사용함으로서 대면적화가 어려웠으며, pulse고전압이나 수kHz 이상의 고주파를 전원으로 사용하는 발생 전원의 비대화를 가져왔다. 본 발명은 일상에서 값싸고 편리하게 취할 수 있는 직류전원 혹은 일반 가정용 전원을 포함하는 저주파 교류전원을 사용하여 손쉽게 코로나 방전을 일으킬 수 있는 방법 및 장치이다. 또한 철망형 평행판 전극을 설치하고 전극 사이에 저항체 장벽을 삽입함으로서 대면적 대기압 코로나 방전이 가능한 장치이다.The present invention relates to large area corona discharges. Corona discharge according to the prior art has been difficult to large area by using a parallel plate or Tip type electrode, and has resulted in an increase in the generated power source using a pulse high voltage or a high frequency of several kHz or more as a power source. The present invention is a method and apparatus that can easily generate a corona discharge using a low-frequency AC power source including a DC power source or a general household power source that can be taken inexpensively and conveniently in everyday life. In addition, a large area atmospheric pressure corona discharge is possible by installing a wire mesh parallel plate electrode and inserting a resistor barrier between the electrodes.
코로나 방전으로 오존을 생성하는 방법은 널리 쓰이고 있지만, 본 발명에서는 공급하는 전원의 차별화와 대면적의 코로나 발생을 위한 철망형 평행판의 전극 개량을 들 수 있다. 본 발명에서 60Hz의 AC로 대면적의 코로나 방전이 가능하게 되는 것은 전극사이에 저항체 장벽을 삽입하여 방전시 저항제의 특징으로 과도한 전류의 흐름을 저항체 장벽이 막아줌으로서 플라즈마가 전압의 변화 없이 스스로 안정하게 된다. 본 발명은 시중에서 값싸게 구할 수 있는 수은등안정기(15kV, 20mA, 60Hz)를 이용하여 얻어진 직류전원을 사용하거나 저주파 교류전원을 전원 공급원으로 사용함으로서 전원공급장치의 경제적인 효과가 있다. 또한 종래 기술이 단순형 전극을 사용하여 모서리 부분에 불균일한 방전이 일어나던 것과는 달리, 철망형 평행판 전극으로 사용함으로서 대면적의 균일한 코로나 방전을 얻을 수 있다. 이렇게 함으로서 본 발명은 대기압 하에서 균일한 코로나 방전을 통한 대면적 표면처리, 대량의 오존발생 등을 손쉽고 값싸게 할 수 있는 장점이 있다.The method of generating ozone by corona discharge is widely used, but in the present invention, there is an electrode improvement of a wire mesh parallel plate for differentiating a power supply to be supplied and generating a large area of corona. In the present invention, a large area corona discharge is possible with AC of 60 Hz, by inserting a resistor barrier between electrodes, which prevents excessive current flow by the resistor barrier. It becomes stable. The present invention is economical effect of the power supply device by using a DC power obtained using a mercury lamp ballast (15kV, 20mA, 60Hz) that can be obtained in the market cheaply or using a low-frequency AC power as a power source. In addition, unlike the prior art, where a nonuniform discharge occurs at the corner portion using a simple electrode, a large area uniform corona discharge can be obtained by using the wire mesh parallel plate electrode. By doing so, the present invention has an advantage that it is easy and inexpensive to treat a large surface area, a large amount of ozone generation, etc. through a uniform corona discharge under atmospheric pressure.
