Description

분산절환식 이온 발생기를 포함한 대전부Charging section including dispersion-switchable ion generator
본 발명은 집진장치에서 코로나 방전을 이용해 미세먼지 입자를 전기적으로 대전시키기 위해 방전극이 분산되고 같은 방전극에서 양이온과 음이온이 교차하여 발생하는 분산절환식 이온 발생기를 포함한 대전부에 관한 것이다.The present invention relates to a charging unit including a dispersion-switched ion generator in which a discharge electrode is dispersed in order to electrically charge fine dust particles using corona discharge in a dust collector, and positive and negative ions cross each other in the same discharge electrode.
일반적으로 전기 집진기의 대전부에서는 방전극에 고전압을 인가하면 방전극의 끝부분에서 코로나 방전이 일어나고, 방전영역 내에서 발생하는 강한 전기장에서 기하급수적으로 진행되는 이온화현상(전자사태)에 의하여 다량의 전자가 코로나 영역 밖으로 이동하여 코로나 영역 밖의 가스 분자와 결합하여 가스를 이온화 시키고, 이온화된 가스는 공기의 흐름 속에 포함된 미세먼지 입자와 결합하여 미세먼지를 전기적으로 대전시킨다. 그리고 대전부에서 대전된 미세먼지는 전기력에 의하여 집진판으로 이동하여 집진판의 표면에 달라붙어 포집되는 원리로 작동된다.In general, in the charging section of an electric precipitator, when a high voltage is applied to the discharge electrode, a corona discharge occurs at the end of the discharge electrode, and a large amount of electrons is transferred by an ionization phenomenon (electron avalanche) that proceeds exponentially in a strong electric field generated in the discharge region. It moves outside the corona area and combines with gas molecules outside the corona area to ionize the gas, and the ionized gas combines with the fine dust particles contained in the air flow to electrically charge the fine dust. In addition, the fine dust charged in the charging unit is moved to the dust collecting plate by electric force, and is attached to the surface of the dust collecting plate to be collected.
그런데 종래에는 대전부에서 미세먼지를 양이온 또는 음이온으로 대전시키며, 집진부에서는 대전된 미세먼지의 극성과 반대되는 극성의 집진판에 대전된 미세먼지가 전기적인 인력에 의해 포집되도록 구성되어 있다. 지하철에 많은 성분 비율로 존재하는 철 성분의 미세먼지는 대전부에서 이온이 쉽게 증착이 되지만 집진부에서는 증착된 이온이 대전판의 상대 이온과 쉽게 중화되어 이온이 빠져나가서 철성분의 미세먼지에 대한 집진 효율이 떨어지는 문제점이 있다.However, conventionally, the charging unit charges fine dust with positive or negative ions, and the dust collecting unit is configured to collect fine dust charged on a dust collecting plate having a polarity opposite to that of the charged fine dust by electric attraction. Iron-based fine dust that exists in a large proportion of the subway is easily deposited in the charging section, but in the dust collecting section, the deposited ions are easily neutralized with the counter ions of the charging plate, so that the ions escape and collect the fine dust of the iron component. There is a problem that the efficiency is inferior.

또한, 방전극(32)은 끝단이 뾰족한 봉 형태 등으로 형성될 수 있으며, 일례로 방전극(32)은 복수의 탄소섬유로 구성된 탄소섬유 다발로 형성되어 방전이 용이하도록 할 수 있다.In addition, the discharge electrode 32 may be formed in the form of a rod having a pointed end. For example, the discharge electrode 32 may be formed of a bundle of carbon fibers composed of a plurality of carbon fibers to facilitate discharge.
그리하여 전원 공급부(10)에서 고전압의 교류 전원이 공급되면 전극(20)의 전류가 스위칭되어 말단 모듈(30)에서 번갈아서 양이온과 음이온이 방출될 수 있다. 즉, 교류 고전압이 각 방전극에 대전이 되어서 양이온과 음이온이 시차를 두고 같은 방전극에서 번갈아 방출이 된다. 이때, 미세먼지를 포함한 공기가 방전극(32)들의 주변을 통과하면서 미세먼지가 양 이온 및 음 이온에 부착되어 대전되며, 이후 공기가 유동되면서 양 이온에 부착된 미세먼지와 음 이온에 부착된 미세먼지가 서로 결합되어 미세먼지들이 응집됨에 따라 조대화된 미세먼지 응집체가 형성될 수 있다. 이에 따라 조대화된 미세먼지 응집체를 집진장치(집진부)에서 포집하기 용이하므로 미세먼지 제거 효율을 향상시킬 수 있다.Thus, when high voltage AC power is supplied from the power supply unit 10, the current of the electrode 20 is switched so that positive and negative ions may be alternately discharged from the terminal module 30. In other words, high AC voltage is charged to each discharge electrode, so that positive and negative ions are alternately discharged from the same discharge electrode at a time difference. At this time, as the air including fine dust passes through the periphery of the discharge electrodes 32, the fine dust is attached to the positive and negative ions to be charged. Then, as the air flows, the fine dust attached to the positive ions and the fine dust attached to the negative ions As the dust is combined with each other and the fine dust is agglomerated, coarse fine dust agglomerates may be formed. Accordingly, since it is easy to collect the coarse fine dust aggregates in the dust collecting device (dust collecting unit), the efficiency of removing fine dust can be improved.
