According to the present invention, in the electrostatic precipitator in which a plurality of dust collecting plates are horizontally coupled between support frames spaced apart from each other in a forward and backward direction, the bending prevention device formed by bending a metal plate is inserted into an upper side in the support frames to prevent bending and distortion of the dust collecting plates (20). The bending prevention device of the present invention comprises: a contact unit being in contact with a rear surface of a support frame by being vertically formed; a support unit fixed by elastic force on a front surface of the support frame; a bent unit formed to be fixed to the support frame at upper sides of the contact unit and the support unit; and an elastic unit for pressing a dust collecting plate by the elastic force. Therefore, the bending prevention device of the present invention can be simply fixed to an upper side of the support frame by the support unit having the elastic force. Also, the elastic unit, which is bent at a predetermined angle compresses the electrostatic precipitator from a front surface to a rear surface to prevent a contact with a discharge electrode caused by bending and distortion of the dust collecting plate, thereby suppressing generation of sparks and remarkably improving the dust collection efficiency of the electrostatic precipitator. In addition, costs required for installation and manufacturing can be reduced due to a simple structure, and maintenance is easy to be more economical.

Description

전기집진기의 집진판용 휨 방지구{Anti-flexure device for dust collecting plate of electrostatic precipitator}Anti-flexure device for dust collecting plate of electrostatic precipitator

본 발명은 산업용 전기집진기에 관한 것으로, 더욱 상세하게는 탄성력에 의해 압착을 가함으로써 집진판의 휘어짐과 비틀림을 미연에 방지할 수 있는 전기집진기의 집진판용 휨 방지구에 관한 것이다.The present invention relates to an industrial electrostatic precipitator, and more particularly, to a deflection prevention tool for a dust precipitator of the electrostatic precipitator, which can prevent the bending and torsion of the precipitator by applying compression by elastic force.

일반적으로 기력발전소 등의 산업용 보일러의 연소가스에는 많은 분진 등이 포함하는데, 이 배기가스 속에 함유된 이러한 분진을 제거하는 장치가 전기 집진기이다. 즉 전기 집진기는 연소가스 속에 부유하고 있는 분진에 전기장을 작용시켜 전기를 띠게 하며 먼지 입자를 정전기적인 힘으로 모아 배기가스를 깨끗하게 하는 장치이다.In general, a large amount of dust is included in the combustion gas of an industrial boiler such as a power plant, and an electric dust collector is a device for removing such dust contained in the exhaust gas. In other words, an electric dust collector is a device that applies an electric field to the dust suspended in the combustion gas to generate electricity, and collects dust particles by electrostatic force to clean the exhaust gas.

상기와 같은 전기 집진기는 코로나 방전을 일으키는 방전극과, 이 방전극에서 방출된 음전하에 음이온화된 분진을 포집하는 집진판 및, 이 집진판에 포집된 분진을 제거하는 추타장치로 구성되어 있다. 여기서 상기 집진판은 길이 14m와 폭 0.6m로 이루어진 7장의 집진판이 1세트 방식인 1열로 설치되는데, 이 집진판의 상부가 현수 형태로 매달려 설치되어 있다.The electrostatic precipitator is composed of a discharge electrode for generating a corona discharge, a dust collecting plate for collecting anionized dust under negative charge emitted from the discharge electrode, and a chase apparatus for removing dust collected in the dust collecting plate. Here, the dust collecting plate is installed in a single row of seven sets of dust collecting plates consisting of 14m in length and 0.6m in width, one set method, the upper part of the dust collecting plate is installed in a suspended form.

도 1 및 도 2는 종래에 의한 집진판(20)의 설치상태를 개략적으로 나타낸 것으로서, 상측과 하측에는 좌우로 연장 형성된 지지프레임(10)이 구비되고, 상기 지지프레임(10)의 사이에는 지그재그 형상인 복수의 집진판(20)이 좌우로 결합되어 있다.1 and 2 schematically show the installation state of the dust collecting plate 20 according to the prior art, the upper and lower side is provided with a support frame 10 extending from side to side, between the support frame 10 in a zigzag shape A plurality of phosphor collecting plate 20 is coupled to the left and right.

상기 지지프레임(10)은 도 2에서 나타낸 바와 같이 집진판(20)의 전면과 후면에 각각 볼트 및 너트에 의해 결합되며, 이렇게 조립된 복수의 집진판 유니트는 전후로 간격을 이루며 설치되고, 각 집진판(20)의 사이에는 방전극(도면 미표시)이 설치된다.The support frame 10 is coupled to the front and rear of the dust collecting plate 20 by bolts and nuts, respectively, as shown in Figure 2, the plurality of dust collecting plate units assembled in this way are installed at intervals before and after, each dust collecting plate 20 Is provided between the discharge electrodes (not shown).

그러나 상기와 같은 종래 집진판 구조에서 이 집진판에 부착된 분진을 털어내기 위해 추타장치 운전시 이 추타장치의 외력에 의하여 현수 형태로 매달린 집진판에 휨과 스윙(Swing) 현상이 발생하게 되며, 이러한 휨 변형에 의한 집진판은 방전극과 간격이 좁아져서 집진판에서 방출한 양이온과 방전극에서 방출한 음이온이 순간적으로 결합하여 스파크가 발생하고 전압이 0으로 떨어지면, 분진을 이온화 시키지 못하므로 포집되지 않는 먼지가 굴뚝을 통해 대기로 방출되어 대기오염이 발생하는 문제점이 있었다.However, in the conventional dust collecting plate structure as described above, in order to shake off the dust attached to the dust collecting plate, the bending and swinging phenomenon occurs in the dust collecting plate suspended in the suspension form by the external force of the thrusting device during the operation of the thruster. The dust collector plate has a narrow gap with the discharge electrode, so that the cations emitted from the dust collector and the anion emitted from the discharge electrode instantly combine with sparks, and when the voltage drops to zero, the dust cannot be ionized. There was a problem that air pollution is emitted to the atmosphere.

이에 따라 작업자가 집진판의 사이로 진입하여 교정작업을 수행해야 하기 때문에 유지관리가 매우 번거로우며 안전사고가 발생하는 문제점이 있었다.Accordingly, since the worker has to enter the dust collecting plate and perform the calibration work, maintenance is very troublesome and there is a problem that a safety accident occurs.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 집진판의 휘어짐과 비틀림을 미연에 방지하여 집진효율을 높일 수 있는 전기집진기의 집진판용 휨 방지구를 제공하는 데 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a bending prevention device for a dust collector plate of an electrostatic precipitator, which can prevent the bending and torsion of the dust collector in advance.

또한, 본 발명의 다른 목적은 단순한 구성 및 결합구조에 의해 제작비용 및 설치비용을 절감할 수 있는 전기집진기의 집진판용 휨 방지구를 제공하는 데 있다.In addition, another object of the present invention is to provide a bending prevention tool for the dust collector plate of the electrostatic precipitator which can reduce the manufacturing cost and installation cost by a simple configuration and coupling structure.

본 발명에 의한 전기집진기의 집진판용 휨 방지구는 전후로 간격을 이룬 지지프레임의 사이에 복수의 집진판이 좌우로 결합된 전기집진기에 있어서, 집진판의 설치가 모든 완료된 후에, 집진판(20)의 휘어짐과 비틀림을 방지할 수 있도록 지지프레임에는 금속판을 절곡 형성하여 형성된 휨방지구가 상측에서 삽입고정되되, 상기 휨 방지구는 수직으로 형성되어 지지프레임의 배면에 밀착되는 밀착부와; 상기 지지프레임의 전면에 탄성력에 의해 고정되는 지지부와; 상기 밀착부와 지지부의 상측에 상기 지지프레임에 고정될 수 있도록 형성된 절곡부와; 탄성력에 의해 집진판을 후방으로 압착하는 탄성부를 포함하여 구성된 것을 그 기술적 특징으로 한다. The deflection prevention tool for the dust collector of the electrostatic precipitator according to the present invention is an electrostatic precipitator in which a plurality of dust collecting plates are coupled from side to side between supporting frames spaced forward and backward, and after the installation of the dust collecting plate is completed, the bending and twisting of the dust collecting plate 20 are completed. A bending prevention tool formed by bending a metal plate is inserted into and fixed from an upper side of the support frame so as to prevent the bending, and the bending prevention tool is formed vertically and in close contact with a rear surface of the support frame; A support part fixed to the front surface of the support frame by an elastic force; A bent portion formed to be fixed to the support frame on an upper side of the contact part and the support part; The technical feature is that it comprises an elastic portion for pressing the dust collecting plate backward by the elastic force.

본 발명에 따른 전기집진기의 집진판용 휨 방지구에 의하면, 탄성력이 있는 지지부에 의해 지지프레임의 상측에 간단히 고정할 수 있으며, 소정의 각도로 절곡된 탄성부가 집진판을 전면에서 후방으로 압착하여 집진판의 휘어짐과 비틀림에 의한 방전극과의 접촉을 방지함으로써 스파크의 발생을 억제하고 전기진집기의 집진효율을 대폭 향상시킬 수 있는 효과가 있다.According to the anti-bending tool for the dust collector plate of the electrostatic precipitator according to the present invention, the elastic support portion can be easily fixed to the upper side of the support frame, and the elastic portion bent at a predetermined angle is pressed against the dust collector plate from the front side to the rear of the dust collector plate. By preventing the contact with the discharge electrode due to bending and torsion there is an effect that can suppress the occurrence of sparks and significantly improve the dust collection efficiency of the electrostatic precipitator.

또한, 단순한 구조로 이루어져 설치 및 제작에 소요되는 비용을 절감할 수 있으며, 유지관리가 용이하여 더욱 경제적인 효과가 있다.In addition, the simple structure can reduce the cost required for installation and manufacturing, there is a more economical effect because of easy maintenance.
