Description

우레탄 필터를 이용한 전기 집진 장치{ELECTRONIC DUST COLLECTING APPARATUS USING URETHANE FILTER}Electric dust collector using urethane filter {ELECTRONIC DUST COLLECTING APPARATUS USING URETHANE FILTER}

본 발명은 전기 집진 장치에 관한 것으로, 특히 먼지 입자를 하전시킨 다음 반대 극성으로 하전된 포집부에서 먼지 입자를 포집하도록 하는 전기 집진 장치에관한 것이다.The present invention relates to an electrostatic precipitator, and more particularly, to an electrostatic precipitator which charges dust particles and then collects the dust particles in the collecting portion charged to the opposite polarity.

일반적으로 집진 장치는 공기 중의 먼지를 포집하기 위한 장치로서, 건물 공조기나 공기 청정기, 항온항습기, 팬코일 유닛 등에 주로 사용된다. 이 가운데 전기 집진 장치는 코로나 방전을 통해 먼지 입자가 전기적 극성을 띄도록 하전시킨 후 반대 극성으로 하전된 포집부에서 발생하는 전기적인 흡인/반발력으로 먼지 입자를 포집한다.Generally, a dust collector is a device for collecting dust in the air, and is mainly used for a building air conditioner, an air purifier, a thermo-hygrostat and a fan coil unit. Among them, the electrostatic precipitator charges the dust particles to have an electrical polarity through corona discharge, and then collects the dust particles by electrical suction / repulsion force generated in the collecting portion charged with the opposite polarity.

도 1은 종래의 전기 집진 장치를 나타낸 도면이다. 도 1에 나타낸 바와 같이, 종래의 전기 집진 장치는 프리필터(102)와 전리부(ionizer, 104), 금속 망(mesh, 106), 포집부(collector, 108)로 구성된다. 프리필터(102)는 비교적 큰 먼지를 일차적으로 걸러내기 위한 것으로서, 플라스틱 등으로 이루어진다. 전리부(104)는 코로나 방전을 통해 먼지 입자를 하전시키기 위한 것이다. 전리부(104)는 (+) 전압이 공급되는 방전선(112)들이 접지 전극(110)들 사이에 위치하여 코로나 방전 현상을 발생시킨다. 먼지 입자는 이 전리부(104)를 통과하면서 (+) 극성으로 하전된다. 금속 망(106)은 하전된 먼지를 일차적으로 걸러내기 위한 것으로서, (+)로 하전된 먼지 입자를 흡착하기 위해 접지된다. 포집부(108)는 여러 개의 격벽(118)으로 구분된 공간마다 코팅 알루미늄 포일(coating Aluminum foil, 114)과 밴딩 알루미늄 포일(banding Aluminum foil, 116)이 서로 어느 정도의 간격을 두고 떨어져 있다. 코팅 알루미늄 포일(114)에는 (+) 전압이 공급되고 밴딩 알루미늄 포일(116)은 접지된다. 따라서 코팅 알루미늄 포일(114)과 밴딩 알루미늄 포일(116) 사이에 (+)로 하전된 먼지 입자가 유입되면 코팅 알루미늄 포일(114)과의 반발력 때문에 접지된밴딩 알루미늄 포일(116) 쪽으로 먼지 입자가 이동하여 흡착 포집된다.1 is a view showing a conventional electric dust collector. As shown in FIG. 1, the conventional electrostatic precipitator includes a prefilter 102, an ionizer 104, a mesh 106, and a collector 108. The prefilter 102 is primarily for filtering relatively large dust, and is made of plastic or the like. The ionizing portion 104 is for charging the dust particles through corona discharge. In the ionizing unit 104, discharge lines 112 supplied with a positive voltage are positioned between the ground electrodes 110 to generate a corona discharge phenomenon. The dust particles are charged with positive polarity while passing through the ionizing portion 104. The metal mesh 106 is primarily for filtering charged dust and is grounded to adsorb positively charged dust particles. The collecting unit 108 has a coating aluminum foil 114 and a banding aluminum foil 116 spaced apart from each other by a space separated by a plurality of partition walls 118. The coated aluminum foil 114 is supplied with a positive voltage and the bending aluminum foil 116 is grounded. Therefore, when a positively charged dust particle flows between the coated aluminum foil 114 and the bending aluminum foil 116, the dust particles move toward the grounded bending aluminum foil 116 due to the repulsive force with the coated aluminum foil 114. Adsorption is collected.

이와 같은 종래의 전기 집진 장치는 포집부(108)가 알루미늄 포일로 구성되기 때문에 생산 원가가 비교적 높다. 또한 밴딩 알루미늄 포일(116)의 표면에서만 포집이 이루어지기 때문에 그 만큼 포집 효율이 떨어진다.The conventional electrostatic precipitator has a relatively high production cost because the collecting unit 108 is made of aluminum foil. In addition, since the collection is made only on the surface of the bending aluminum foil 116, the collection efficiency is reduced by that much.

본 발명에 따른 우레탄 필터를 이용한 전기 집진 장치는 기존의 알루미늄 포일 대신 미세한 포집공을 무수히 형성시킨 우레탄 필터를 사용하여 생산 원가를 낮추는데 그 목적이 있다. 또한 본 발명은 우레탄 필터에 전계를 형성시켜서 (+)로 하전된 먼지 입자의 직진성을 떨어뜨림으로서 먼지 입자의 포집 효율을 향상시키는 또 다른 목적을 가지고 있다.The electrostatic precipitator using the urethane filter according to the present invention has an object of lowering the production cost by using a urethane filter having a myriad of fine collecting holes instead of the existing aluminum foil. In addition, the present invention has another object of improving the collection efficiency of dust particles by forming an electric field in the urethane filter to reduce the linearity of the dust particles charged with (+).

이와 같은 목적의 본 발명에 따른 우레탄 필터를 이용한 전기 집진 장치는 전리부와 포집부를 포함하여 이루어진다. 먼저 전리부는 먼지 입자를 하전시키기 위한 것이다. 포집부는 적어도 하나의 우레탄 필터를 구비하고, 이 우레탄 필터를 통해 먼지 입자를 흡착 포집한다.Electrostatic precipitator using a urethane filter according to the present invention for this purpose comprises an ionizing portion and a collecting portion. First, the ionizing portion is for charging dust particles. The collecting portion includes at least one urethane filter, and absorbs and collects dust particles through the urethane filter.

본 발명에 따른 우레탄 필터를 이용한 전기 집진 장치의 바람직한 실시예를 도 2와 도 3을 참조하여 설명하면 다음과 같다. 먼저 도 2는 본 발명에 따른 우레탄 필터를 이용한 전기 집진 장치를 나타낸 도면이다. 도 2에 나타낸 바와 같이, 본 발명에 따른 전기 집진 장치는 프리필터(202)와 전리부(ionizer, 204), 포집부(collector, 208)로 구성된다. 프리필터(202)는 비교적 큰 먼지를 일차적으로 걸러내기 위한 것으로서, 플라스틱 등으로 이루어진다. 전리부(204)는 코로나 방전을 통해 먼지 입자를 하전시키기 위한 것이다. 전리부(104)는 (+) 전압이 공급되는 방전선(212)들이 접지 전극(210)들 사이에 위치하여 코로나 방전을 일으킨다. 먼지 입자는 이 전리부(204)를 통과하면서 (+) 극성으로 하전된다.A preferred embodiment of the electrostatic precipitator using the urethane filter according to the present invention will be described with reference to FIGS. 2 and 3 as follows. 2 is a view showing an electrostatic precipitator using a urethane filter according to the present invention. As shown in FIG. 2, the electrostatic precipitator according to the present invention includes a prefilter 202, an ionizer 204, and a collector 208. The prefilter 202 is primarily used for filtering relatively large dust, and is made of plastic or the like. The ionizing portion 204 is for charging the dust particles through corona discharge. In the ionizing unit 104, discharge lines 212 supplied with a positive voltage are positioned between the ground electrodes 210 to generate corona discharge. Dust particles are charged with positive polarity while passing through this ionizing portion 204.

포집부(108)는 두 개의 금속 망(206, 216) 사이에 우레탄 필터(urethane filter, 214)가 삽입되어 이루어진다. 앞 쪽의 금속 망(206)은 하전된 먼지를 일차적으로 걸러내기 위한 것으로서, (+)로 하전된 먼지 입자를 걸러내기 위해 접지된다. 우레탄 필터(214) 뒤 쪽의 금속 망(216)에는 직류 전압(DC)이 공급된다. 이 때문에 두 금속 망(206, 216) 사이에는 전계(E)가 화살표 방향으로 형성된다. 이 전계(E)에 의해 우레탄 필터(214)에 분극 현상(polarization)이 일어난다.The collecting part 108 is formed by inserting a urethane filter 214 between two metal meshes 206 and 216. The front metal mesh 206 is primarily for filtering charged dust and is grounded to filter out positively charged dust particles. The DC voltage DC is supplied to the metal mesh 216 behind the urethane filter 214. For this reason, an electric field E is formed between the two metal meshes 206 and 216 in the direction of the arrow. The electric field E causes polarization of the urethane filter 214.

우레탄 필터(214)에는 무수히 많은 미세한 포집공들(도시하지 않았음)이 형성되어 있다. 이 먼지 입자는 이 포집공들을 통과하면서 분극이 일어난 우레탄 필터(214)의 (-) 극성 부분에 흡착 포집된다. 즉, 먼지 입자가 단순히 우레탄 필터(214)의 표면에 흡착되는 것이 아니라 우레탄 필터(214)에 형성된 무수한 포집공들 내에 포집되기 때문에 그만큼 포집 효율이 높다.The urethane filter 214 is formed with a myriad of fine collecting holes (not shown). The dust particles are absorbed and collected in the negative polar portion of the urethane filter 214 where polarization occurs while passing through the collecting holes. That is, since the dust particles are not simply adsorbed on the surface of the urethane filter 214 but are collected in the countless collecting holes formed in the urethane filter 214, the collection efficiency is as high as that.

또한 두 금속 망(206, 216) 사이에 형성된 전계(E)에 의해 전리부(204)에서 금속 망(206) 방향으로 이동하는 먼지 입자의 직진성이 감소되어 포집부(208) 내에 상대적으로 더 오래 머무르게 되어 우레탄 필터(214)에서의 포집 효율이 향상된다.In addition, the straightness of the dust particles moving from the ionizing portion 204 toward the metal mesh 206 by the electric field E formed between the two metal meshes 206 and 216 is relatively longer in the collecting portion 208. As a result, the collection efficiency in the urethane filter 214 is improved.

도 3은 본 발명에 따른 우레탄 필터를 이용한 전기 집진 장치의 또 다른 실시예를 나타낸 도면으로서, 두 개의 우레탄 필터를 구비한 경우를 나타내었다. 도 3에 나타낸 바와 같이, 프리필터(302)와 전리부(304)의 구성은 동일하며, 다만 포집부(314)에 우레탄 필터(318)와 금속 망(320)이 더 추가되었다. 추가된 금속 망(320)은 접지되기 때문에 추가된 우레탄 필터(318)에는 전계(E2)가 형성된다.3 is a view showing another embodiment of an electrostatic precipitator using a urethane filter according to the present invention, showing a case having two urethane filters. As shown in FIG. 3, the configurations of the prefilter 302 and the ionizing unit 304 are the same, except that the urethane filter 318 and the metal mesh 320 are further added to the collecting unit 314. Since the added metal mesh 320 is grounded, an electric field E2 is formed in the added urethane filter 318.

첫 번째 우레탄 필터(308)에서 미처 포집되지 않은 먼지 입자는 금속 망(316)을 통과해 두 번째 우레탄 필터(318)에서 다시 한번 포집된다. 또 두 번째 우레탄 필터(318)에서도 미처 포집되지 않은 먼지 입자는 (+) 극성을 띄기 때문에 접지된 금속 망(320)에 의해 다시 한번 포집된다. 이처럼 우레탄 필터(318)와 금속 망(320)을 추가함으로써 포집 효율이 극대화된다.Dust particles not captured in the first urethane filter 308 pass through the metal mesh 316 and are once again collected in the second urethane filter 318. In the second urethane filter 318, the dust particles that are not collected are collected again by the grounded metal mesh 320 because they have positive polarity. As such, by adding the urethane filter 318 and the metal mesh 320, the collection efficiency is maximized.

본 발명에 따른 우레탄 필터를 이용한 전기 집진 장치는 기존의 알루미늄 포일 대신 미세한 포집공을 무수히 형성시킨 우레탄 필터를 사용하여 생산 원가를 낮출 수 있다. 또한 우레탄 필터에 전계를 형성시켜서 (+)로 하전된 먼지 입자의 직진성을 떨어뜨림으로서 우레탄 필터를 통과하는 시간을 증가시켜서 먼지 입자의 포집 효율을 크게 향상시킨다.The electrostatic precipitator using the urethane filter according to the present invention can lower the production cost by using a urethane filter in which a number of fine collecting holes are formed instead of the existing aluminum foil. In addition, by forming an electric field in the urethane filter to reduce the linearity of the positively charged dust particles to increase the time to pass through the urethane filter to greatly improve the dust particles collection efficiency.
