본 발명은 전기집진기에 관한 것으로, 특히 대전부재와 방전부재를 설치할때 사각지대를 없애도록 동일면적에 많은 방전전극을 설치하여 집진부의 설치면적을 더많이 제공함과 동시에 방전효과를 증대시켜 집진성능을 향상시킬 수 있도록한 전기집진기에 관한 것이다.The present invention relates to an electrostatic precipitator, in particular, to install more discharge electrodes in the same area to eliminate the blind spot when installing the charging member and the discharge member to provide more installation area of the dust collector and at the same time increase the discharge effect to increase the dust collection performance. It relates to an electrostatic precipitator that can be improved.

일반적으로 전기집진기는, 고압의 전기를 이용하여 흡입된 먼지를 분해, 대전시킨 후 반대전하를 띤 집진판에 먼지가 흡착제거되도록 되어 있다.In general, an electrostatic precipitator is used to decompose and charge dust sucked by using high-pressure electricity, so that the dust is adsorbed and removed on the antistatic dust collector plate.

즉, 종래의 전기집진기는 제1도 및 제2도에 도시한 바와같이, 고압의 전기를 인가받아전하를 띠도록 된 방전부재(1)는, 후술하는 대전부재(2)를 향해 방전시켜 주도록 다수개의 방전전극(1a)이 지지부(1b)에 의해 일정한 간격을 두고 상하, 좌우 방향으로 연속되게 일체로 설치되어 있다. 이때 상기 방전전극(1a)은 선단이 뾰족한 침상의 형상을 갖도록 되어 있다.That is, the conventional electrostatic precipitator receives high voltage electricity as shown in FIGS. 1 and 2. In the discharge member 1 to be charged, a plurality of discharge electrodes 1a are integrated in the vertical, horizontal and vertical directions at regular intervals by the support 1b so as to discharge toward the charging member 2 described later. It is installed. At this time, the discharge electrode (1a) is to have a needle-like shape of the pointed tip.

한편, 대전부재(2)는 고압의 전기를 인가받아전하를 띠도록 되어 있는 것으로서, 이 대전부재(2)의 판상에는 다수개의 사각홀(2a)를 뚫어서 그 사각홀(2a)의 하부측 일부에는 한쪽 방향으로 대향되면서 연속적으로 반복되는 집진부(2b)가 수직되게 절곡 형성되어 있으며, 또 대전판(2)의 가장자리에는 상기 집진부(2b)와 동일한 방향으로 수직되게 절곡된 절곡부(2c)가 형성되어서, 상기 방전부재(1)의 상측에 설치되면서 방전부재(1)의 방전전극(1a)dl 상기 사각홀(2a)의 중앙에 위치하도록 되어 있다. 이때 상기 방전전극(1a)의 선단부, 즉 뾰족한 침상의 선단부는 상기 사각홀(2a)의 수평부와 대체로 비슷한 높이를 갖도록 수직되게 설치되어서 방전부재(1)와 대전부재(2)와의 간격을 주도록 설치되어 있었다.On the other hand, the charging member 2 is applied with a high voltage electricity The dust collecting part 2b is formed so as to carry an electric charge, and a plurality of square holes 2a are drilled on the plate of the charging member 2, and the lower part of the square hole 2a is repeatedly opposed while being opposed to one side in one direction. Is bent vertically, and the bent portion 2c bent vertically in the same direction as the dust collecting part 2b is formed at the edge of the charging plate 2, and is installed above the discharge member 1, The discharge electrode 1a dl of the discharge member 1 is positioned at the center of the square hole 2a. In this case, the distal end of the discharge electrode 1a, that is, the tip of the pointed needle, is vertically installed to have a height substantially similar to that of the horizontal hole of the square hole 2a, so as to give a gap between the discharge member 1 and the charging member 2. It was installed.

그러나, 이와 같이 구성된 종래의 전기집진기는전하를 갖는 방전부재(1)의 방전전극(1a)이전하를 갖는 대전부재(2)의 집진부(2b)를 향하여 연속적으로 방전시켜줄때, 상기 삽입홀(2a)을 통과하는 함진공기에 부유하는 먼지가 고압의 방전파에 의하여 미세한 입자로 분해됨과 동시에전하를 띤 이온화된 먼지가 되면서 상기 집진부(2b)에 흡착제거되도록 되어 있기 때문에 제2도와 같이 빗금표시된 부분에는 이온화되지 않은 먼지가 그대로 통과되는 사각지대가 발생되어 집진 효율이 저하된다는 문제점이 있었다.However, the conventional electrostatic precipitator configured as described above The discharge electrode 1a of the discharge member 1 having electric charge When continuously discharged toward the dust collecting portion 2b of the charging member 2 having electric charge, the dust floating in the vacuum air passing through the insertion hole 2a is decomposed into fine particles by the high-pressure discharge wave. Since the ionized dust is charged and removed by the dust collecting part 2b, a blind spot through which unionized dust passes as shown in FIG. 2 is generated, thereby reducing dust collection efficiency.

또한, 상기 방전부재(1)의 방전전극(1a)을 선단이 뾰족한 침상으로 형성되어 있기 때문에 전기집진기를 장기간 사용할 경우 방전전극(1a)의 선단부가 마모되어서 집진부(2b)를 향해 충, 방전이 불가능하게 되어, 이를 통과하는 함진공기에 부유하는 먼지는 집진화되지 않은 상태로 실내로 방출되기 때문에 인체에 악영향을 준다는 문제점도 있었다.In addition, since the tip of the discharge electrode 1a of the discharge member 1 is formed with a needle-like tip, when the electrostatic precipitator is used for a long time, the tip of the discharge electrode 1a is worn out to charge and discharge toward the dust collector 2b. It becomes impossible, and there is also a problem that the dust floating in the air containing the air passing therethrough adversely affects the human body because it is released into the room without being collected.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로써, 본 발명의 목적은, 평평한 면상에 동심원을 갖는 방전부재의 방전전극과 이에 대응되어서 방전되는 대전부재의 대전부를 상호 교대로 반복되게 설치함과 동시에 그 중간부에도 동심원을 갖는 방전전극과 이에 대응되어서 방전되는 대전부를 상호 교대로 설치되게 함으로써, 사각지대를 없애고 동일면적에 많은 방전전극을 설치하여 집진부의 설치면적을 크게함과 동시에 집진성능을 향상시킬 수 있는 전기집진기를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to alternately repeat the discharge electrode of the discharge member having a concentric circle on a flat surface and the charging portion of the charging member discharged in correspondence thereto. At the same time, the discharge electrode having concentric circles and the charging portion discharged corresponding thereto are alternately installed in the middle, thereby eliminating blind spots and installing many discharge electrodes in the same area, thereby increasing the installation area of the dust collector. It is to provide an electrostatic precipitator that can improve the dust collection performance.

다음에는, 상기와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Next, the operational effects of the present invention configured as described above are as follows.

함진공기가 제공되면 방전부재(3)에는 고압발생기(3-4Kv ; 도시안됨)에서 발생된 고전압이 고압케이블(도시안됨)을 따라전원이 인가되고, 대전부재(4)에는 고압발생기에서 발생된 고전압이 고압케이블을 따라전원이 인가된다. 이때 방전부재(3)의 주방전전극(3b)과 보조방전전극(3c)은 대전부재(4)의 주대전전극(4a)과 보조대전전극(4b)을 향하여 연속적으로 고압의 방전파를 일으킴으로써 방전부재(3)와 대전부재(4)와의 사이를 통과하는 함진공기에 부유하는 먼지를 미세한 입자로 분해시킴과 동시에로 이온화된 먼지를전하를 띠는 집진판(8)에 흡착제거되도록 하고, 또 이 집진판(8)에 흡착되지 않고 통과된 먼지(로 이온화된 먼지)는 활성탄 필터(9)에 의해 필터링됨과 동시에 냄새가 제거됨으로써 깨끗한 공기만이 전기 집진기를 통해 배출된다. 이 경우 방전부재(3)와 대전부재(4)는 평평한 면상에서 함진공기가 통과될 수 있는 일정한 간격을 두고 동심원을 갖는 주,보조방전전극(3b)(3c)과 주,보조대전전극(4a)(4b)이 동일면적에 많이 설치되어 있어 어느 한쪽에서 방전되는 현상이 없고 전면에 걸쳐서 방전이 이루어지므로 방전효과가 증대됨과 동시에 집진성능이 향상되는 것이다.When the vacuum air is provided, the discharge member 3 has a high voltage generated from a high pressure generator (3-4Kv; not shown) along the high voltage cable (not shown).

By decomposing the dust floating in the vacuum air passing between the discharge member 3 and the charging member 4 into fine particles Ionized dust The dust that is passed through without being adsorbed by the charged dust collecting plate 8 and is not absorbed by the dust collecting plate 8 Furnace ionized dust is filtered by the activated carbon filter 9 and the odor is removed, so that only clean air is discharged through the electric dust collector. In this case, the discharge member 3 and the charging member 4 have main, auxiliary discharge electrodes 3b, 3c, and main, auxiliary charge electrodes 4a having concentric circles at regular intervals through which the impregnated air can pass on a flat surface. (4b) is installed in the same area, so there is no discharge on either side, and discharge occurs over the entire surface, so that the discharge effect is increased and the dust collection performance is improved.
