Description
【０００１】[0001]
本考案は、高電圧を印加した電極間に空気を流通させ、工場排煙中の白煙やミ ストを静電吸着除去する電気集塵装置に関するものである。 The present invention relates to an electrostatic precipitator that allows air to flow between electrodes to which a high voltage is applied to electrostatically remove white smoke and mist in factory exhaust.
【０００２】[0002]
電気集塵装置は、線状または針状の荷電電極により空気中の塵埃や工場排煙等 の微小粒子を帯電させた後、極性の異なる集塵電極板を通過させることで、クー ロン力により微小粒子を静電吸着して大気を浄化している。従来、工業用電気集 塵装置の構造は、円筒状の集塵極の中心にコロナ放電を行う放電極を設けており 集塵極と放電極の間隔は１２．５ｃｍという値が採用されており、近来では２０ から３０ｃｍという大きな間隔値の採用が普及している。また白煙を消去する装 置としてアフターバーナを用いて飽和蒸気以下にして白煙を局部的に消去する方 法もあるが装置が大がかりになりランニングコストも高く、重油を燃焼するので さらに環境を汚染するという致命的な欠陥もある。 The electrostatic precipitator uses a linear or needle-shaped charging electrode to charge fine particles in the air, such as dust in the air and factory flue gas, and then passes the dust collecting electrode plates with different polarities to generate Coulomb force. It cleans the atmosphere by electrostatically adsorbing fine particles. Conventionally, in the structure of an industrial electrostatic precipitator, a discharge electrode for corona discharge is provided at the center of a cylindrical dust collecting electrode, and the distance between the dust collecting electrode and the discharge electrode is 12.5 cm. In recent years, the adoption of a large gap value of 20 to 30 cm has become popular. There is also a method of locally eliminating white smoke by using an afterburner as a device for eliminating white smoke to reduce it to saturated steam or less, but the equipment becomes bulky, the running cost is high, and heavy oil is burned to further reduce the environment. There is also the fatal flaw of pollution.
【０００３】[0003]
しかし、このような従来の構造の集塵電極は、工場排煙中のダストのように有 害な物質については基準値をクリアしているが白煙などのミスト状の物質に関し ては効果が無く工場の煙突から白煙を消去する電気集塵装置はこれまで発明され ていなかった。 However, the dust collecting electrode with such a conventional structure clears the standard value for harmful substances such as dust in factory smoke, but is not effective for mist-like substances such as white smoke. No electric dust collector has ever been invented to eliminate white smoke from a factory chimney.
【０００４】 本考案は以上の問題点を解決するためになされたものであって、工場排煙中の 白煙および霧状の微量汚染物質の除去を目的とする。The present invention has been made to solve the above problems, and its purpose is to remove white smoke and mist-like trace pollutants in factory exhaust gas.

本考案の白煙除去装置は、金属円筒管中に張った金属細線に高電圧を印加し工 場排煙等の浮遊微粒子を静電吸着、除去する円筒型電気集塵装置において、高圧 放電線（１）と円筒電極（２）の間隔を４０ｍｍ以下と狭く帯電した粒子に十分 強力なクーロン力が働き、円筒電極（２）に吸引、液化させ、白煙やミスト状物 質の除去を可能とする構造としている。 The white smoke removing device of the present invention is a cylindrical electrostatic precipitator that electrostatically adsorbs and removes suspended particles such as factory smoke by applying a high voltage to a thin metal wire stretched in a metal cylindrical tube. The distance between (1) and the cylindrical electrode (2) is as narrow as 40 mm or less, and a sufficiently strong Coulomb force acts on charged particles, and the cylindrical electrode (2) is sucked and liquefied to remove white smoke and mist-like substances. And the structure.

以上の構成の白煙除去装置によれば、空気取入口（３）から円筒電極（２）内 へ入った白煙は、円筒電極（２）の中心に張った高圧放電線（１）により帯電し た後、円筒電極（２）に静電吸着され、清浄な空気となって空気吹出口（４）か ら排出される。 According to the white smoke removing device having the above structure, the white smoke that has entered the cylindrical electrode (2) from the air intake (3) is charged by the high-voltage discharge wire (1) stretched at the center of the cylindrical electrode (2). After that, it is electrostatically adsorbed on the cylindrical electrode (2) and becomes clean air, which is discharged from the air outlet (4).

FIG. 1 is a side sectional view showing the internal structure of an embodiment of the present invention, and FIG. 2 is a perspective view showing its appearance. In the figure, (8) is a casing of the white smoke removing device of the present invention, which is formed of a rigid material such as a thin metal plate into a columnar shape or a prismatic shape, and the inside thereof has a cylindrical electrode (2) and a high voltage. A discharge line (1) is formed. (3) is an air inlet provided on the lower surface of the casing (8) for removing white smoke and mist-like substances by introducing them into the cylindrical electrode (2) through the tapered tube (5). (4) is an air outlet for discharging the air purified by the cylindrical electrode (2).

(2) is a cylindrical electrode formed by forming a thin metal plate into a cylindrical shape, and is erected at the center of the device by a tapered tube (5). (1) is a high-voltage discharge wire using a stainless wire, which is stretched at the center of the cylindrical electrode (2) by a high-voltage connector (7) installed on the upper surface of the device and an insulator (6) installed on the lower surface. ing.
【０００９】 以上の構成の白煙除去装置において、その集塵作用について説明する。図示し ない高圧電源をＯＮにすると、高圧電源にて発生したプラス電圧が高圧放電線（ １）へ、同様にマイナス電圧が円筒電極（２）へそれぞれ印加された状態で円筒 電極（２）内でコロナ放電が開始する。このとき工場排煙中の比較的大きな塵埃 は従来の工業用電気集塵機により捕集され円筒電極（２）には捕集できなかった 白煙やミストといった浮遊微粒子が吸い込まれている。円筒電極（２）へ吸い込 まれた白煙は高圧放電線（１）のコロナ放電によって塵埃や白煙といった微小粒 子をプラスに帯電し、マイナス電圧が印加されている円筒電極（２）に静電吸着 されるが、本考案では高圧放電線（１）と円筒電極（２）の間隔を２０ｍｍ〜４ ０ｍｍと極端に狭くした事により白煙やミストといった微小粒子が吸着除去でき る。出願人が行ったミスト吸着試験では、円筒電極（２）の大きさを内径４０ｍ ｍ、長さ５００ｍｍ、風速２ｍ／ｓとした場合、印加電圧７ｋＶでミストを完全 に除去できかなりの効果が得られた。The dust collecting function of the white smoke removing device having the above configuration will be described. When a high-voltage power supply (not shown) is turned on, the positive voltage generated by the high-voltage power supply is applied to the high-voltage discharge line (1), and similarly, the negative voltage is applied to the cylindrical electrode (2) inside the cylindrical electrode (2). Then the corona discharge starts. At this time, relatively large dust in the factory flue gas is collected by the conventional industrial electrostatic precipitator, and suspended particulates such as white smoke and mist which cannot be collected in the cylindrical electrode (2) are sucked. The white smoke sucked into the cylindrical electrode (2) positively charges fine particles such as dust and white smoke by corona discharge of the high-voltage discharge line (1), and the cylindrical electrode (2) to which a negative voltage is applied. It is electrostatically adsorbed, but in the present invention, fine particles such as white smoke and mist can be adsorbed and removed by making the distance between the high-voltage discharge line (1) and the cylindrical electrode (2) extremely narrow, from 20 mm to 40 mm. According to the mist adsorption test conducted by the applicant, when the size of the cylindrical electrode (2) is 40 mm in inner diameter, 500 mm in length, and 2 m / s in wind speed, the mist can be completely removed at the applied voltage of 7 kV, and a considerable effect can be obtained.

【００１０】 なお、本実施例では、単体で実験を行っているが実際の煙突に装着するには、 煙突の内径にあわせて複数の装置を並列に接続しコストおよび必要とされる集塵 効率との兼ね合いで任意に設定してもよい。In addition, in this embodiment, an experiment is conducted by itself, but in order to install the device in an actual chimney, a plurality of devices are connected in parallel according to the inner diameter of the chimney, and the cost and required dust collection efficiency are set. It may be arbitrarily set in consideration of the above.
