Description

플라즈마 집진장치plasma dust collector
본 발명은 플라즈마 집진장치에 관한 것으로, 보다 상세하게는 직하방식의 플라즈마 발생모듈을 이용하는 집진장치에 관한 것이다.The present invention relates to a plasma dust collection device, and more specifically, to a dust collection device using a direct-type plasma generation module.
오염된 공기를 깨끗하게 정화하는 용도로 많이 사용되는 헤파필터(high efficiency particulate air filter)는, 필터링 시간이 누적됨에 따라 먼지 등의 오염으로 인해 세척이 어려워서, 교체되야 하는 단점을 갖는다.HEPA filters (high efficiency particulate air filters), which are widely used to purify polluted air, have the disadvantage that they are difficult to clean due to contamination such as dust as filtering time accumulates and must be replaced.
헤파필터의 단점을 보완할 수 있는 공기정화 수단으로 이용되는 전기집진장치는 필터를 교체해야 하는 번거로움이 없는 대신에, 대전작용 및 집진작용에 전기 에너지를 소모한다는 단점을 갖는다.Electric dust collectors, which are used as an air purification means to compensate for the shortcomings of HEPA filters, do not have the hassle of replacing filters, but have the disadvantage of consuming electrical energy for charging and dust collection.
시간대비 정화되는 공기의 양을 나타내는 공기정화율에 있어서, 헤파필터 대비 전기집진장치의 공기정화율이 낮기 때문에, 전기집진장치는 오랜시간 동안 동작시켜야 하는 단점도 갖는다.Regarding the air purification rate, which represents the amount of air purified over time, the air purification rate of the electrostatic precipitator is lower than that of the HEPA filter, so the electrostatic precipitator has the disadvantage of having to be operated for a long time.
이러한 단점은 오염된 공기가 분포하는 넓은 공간 대비 대전부를 구성하는 와이어 형상의 대전전극이 커버할 수 있는 공간이 좁기 때문에 발생한다.This disadvantage occurs because the space that can be covered by the wire-shaped charging electrodes that make up the charging unit is narrow compared to the large space where polluted air is distributed.
플라즈마 발생장치는 양의 전극과 음의 전극에 수kV에서 수천kV의 고전압을 인가하여 부분적인 방전이 일어나게 하는 장치이다. 플라즈마 발생장치는 일반적으로 공기청정기 또는 에어컨과 같은 전자기기에 장착되어 사용된다. 예를 들어, 공기청정기는 내부에 설치된 플라즈마 발생장치로부터 발생된 양(+)이온 및 음(-)이온을 공기와 함께 송풍하여 실내 공간을 청정하고, 플라즈마 발생 장치가 설치된 에어컨은 실내 공간에 냉기를 송풍할 때 양이온 및 음이온을 함께 송풍하여 냉각과 동시에 실내 공간을 청정한다.A plasma generator is a device that causes partial discharge by applying a high voltage of several kV to several thousand kV to the positive and negative electrodes. Plasma generators are generally used by being mounted on electronic devices such as air purifiers or air conditioners. For example, an air purifier purifies the indoor space by blowing out positive (+) and negative (-) ions generated from a plasma generator installed inside along with the air, and an air conditioner installed with a plasma generator blows cold air into the indoor space. When blowing, positive and negative ions are blown together to cool and clean the indoor space at the same time.
종래 기술에 따른 플라즈마 발생장치도 양의 전극과 음의 전극으로 구성된 플라즈마 발생모듈이 단위 시간당 처리할 수 공기의 체적이 적어서 플라즈마를 이용한 공기 이온화 효율이 낮은 것이 단점이었다.The plasma generator according to the prior art also had a disadvantage in that the plasma generation module consisting of a positive electrode and a negative electrode could process a small volume of air per unit time, so the efficiency of air ionization using plasma was low.
