Description

전기집진기 및 그 제어방법Electrostatic precipitator and its control method

본 발명은 전기집진기 및 그 제어방법에 관한 것으로서, 특히, 전원의 차단시 집진부의 집진판 및 이온화부의 텅스텐선에 잔류하는 전류를 방전시킬 수 있도록 한 전기집진기 및 그 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrostatic precipitator and a control method thereof, and more particularly, to an electrostatic precipitator and a control method thereof capable of discharging a current remaining in the dust collecting plate of the dust collecting unit and the tungsten wire of the ionization unit when the power is cut off.

전기집진기는, 통상적으로 공기청정기 또는 공조기기에 장착되어 실내공기속에 포함된 부유물질을 집진하여 실내공기를 청정하게 된다.An electrostatic precipitator is typically installed in an air purifier or an air conditioner to collect floating materials contained in the indoor air to clean indoor air.

제1도는 전기집진기의 분해사시도이다. 전기집진기는, 전면프레임(2)과 후면프레임(3)으로 분할되는 사각판상의 프레임(1)내에, 흡입되는 공기의 부유물질을 이온화하는 이온화부(10)와, 이온화된 부유물질을 집진하는 집진부(20)가 설치되어 있으며, 이 이온화부(10)와 집진부(20)는 고전압을 발생시키는 도시않은 고전압발생부와 연결되어 전압을 공급받는다.1 is an exploded perspective view of the electrostatic precipitator. The electrostatic precipitator collects the ionizer 10 for ionizing the suspended solids of the air to be sucked and the ionized suspended solids in the frame 1 of the rectangular plate divided into the front frame 2 and the rear frame 3. The dust collector 20 is installed, and the ionizer 10 and the dust collector 20 are connected to a high voltage generator (not shown) for generating a high voltage to receive a voltage.

여기서, 집진부(20)는, 후면프레임(3)내에 알루미늄판으로 형성된 제1집진판과 폴리에틸렌 등의 수지로 코팅된 알루미늄판으로 형성된 제2집진판이 설치되어 있다. 제1집진판과 제2집진판은 소정의 간격을 두고 고정부(24)를 중심으로 후면 프레임(3)내에 원주방향을 따라 일측방향으로 감겨져 있어, 반경방향을 따라 제1집진판과 제2집진판이 교대로 배치되게 된다. 이러한 집진부(20)의 전면에는 집진판(25)으로부터의 전류가 골고루 분포하도록 알루미늄 망사체로 형성된 스크린(29)이 장착되게 된다.Here, the dust collector 20 is provided with a first dust collector plate made of an aluminum plate and a second dust collector plate made of an aluminum plate coated with a resin such as polyethylene in the rear frame 3. The first dust collecting plate and the second dust collecting plate are wound in one direction along the circumferential direction in the rear frame 3 about the fixing part 24 at predetermined intervals, so that the first dust collecting plate and the second dust collecting plate are alternately along the radial direction. To be placed. The front surface of the dust collector 20 is mounted with a screen 29 formed of an aluminum mesh so that the current from the dust collector 25 is evenly distributed.

한편, 이온화부(10)는 전면프레임(2)에 형성되며, 전면프레임(2)내에는 고전압발생부로부터 고전압을 공급받는 복수의 텅스텐선(15)이 전면프레임(2)의 판면을 따라 일정 간격을 두고 지그재그로 배치되어 있다. 이러한 각 텅스텐선(15)의 사이사이에는 텅스텐선(15)의 길이방향을 따라 긴 복수의 접지판(12)이 판면의 가로방향으로 기립배치되어 있다.On the other hand, the ionizer 10 is formed on the front frame 2, a plurality of tungsten wire 15 is supplied along the plate surface of the front frame 2, the high voltage from the high voltage generating unit in the front frame (2) It is arranged zigzag at intervals. Between each of these tungsten wires 15, a plurality of ground plates 12 long along the longitudinal direction of the tungsten wires 15 are erected in the transverse direction of the plate surface.

이러한 전기집진기에 전원을 공급하면, 이온화부(10)의 텅스텐선(15)에는 5kv의 고전압이 공급되고 접지판(12)은 접지된다. 이에 따라, 텅스텐선(15)에서 접지판(12)을 향해 전계가 형성되며 플라즈마 분위기를 조성하여 이온화부(10)를 통과하는 부유물질들을 양이온화한다. 한편, 집진부(20)에서는 제1집진판은 접지되고, 제2집진판은 2.5kv의 고전압이 공급되며, 이에 따라, 제2집진판에서 제1집진판으로 전계가 형성되어 양이온화된 부유물질들을 집진부(20)를 통과하면서 제1집진판에 집진되게 된다.When power is supplied to the electrostatic precipitator, a high voltage of 5kv is supplied to the tungsten wire 15 of the ionizer 10, and the ground plate 12 is grounded. Accordingly, an electric field is formed from the tungsten wire 15 toward the ground plate 12 to form a plasma atmosphere to cation the suspended substances passing through the ionization unit 10. Meanwhile, in the dust collector 20, the first dust collector plate is grounded, and the second dust collector plate is supplied with a high voltage of 2.5 kv.

Due to the continuous operation, suspended solids are accumulated in the dust collector 20 in the dust collector 20, and thus, the suspended solids are periodically removed from the air conditioner or the air cleaner. It should be removed.

그런데, 이러한 전기집진기는 전원을 차단한 뒤에도 집진부(20)의 제2집진판과 이온화부(10)의 텅스텐선(15)에 충전된 고전압이 잔류되어 있으며, 전기집진기를 탈착시킨 직후에 제2집진판과 텅스텐선(15)에 인체가 접촉하였을 경우, 고전압이 인체를 통해 방전되어 인체가 감전당할 염려가 있다. 따라서, 전기집진기의 탈착시 잔류하는 고전압이 인체로 방전되는 것을 방지할 수 있도록 하여야 할 것이다.However, the electrostatic precipitator remains a high voltage charged in the second dust collector plate of the dust collector 20 and the tungsten wire 15 of the ionizer 10 after the power is cut off, the second dust collector plate immediately after removing the electrostatic precipitator When the human body is in contact with the tungsten wire 15, high voltage is discharged through the human body may cause electric shock. Therefore, the high voltage remaining during the desorption of the electrostatic precipitator should be prevented from being discharged to the human body.

따라서 본 발명의 목적은, 전원의 차단시 잔류하는 고전압이 인체로 방전되는 것을 방지할 수 있는 전기집진기 및 그 제어방법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide an electrostatic precipitator and a method of controlling the same, which can prevent the high voltage remaining during the interruption of the power supply to the human body.
