〔産業上の利用分野〕
本発明は荷電部と集塵部とからなる電気集塵器の構成に
間する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the structure of an electrostatic precipitator comprising a charging section and a dust collecting section.
従来の装置は、実開平１−１６３４５１号公報及び実開
平１−１６３４５２号公報に記載のように、陽極板に絶
縁性被膜を形成したり、または接地極板に導電性被膜を
形成し、粉塵が付着しても洗浄時には、粉塵が簡単に除
去できるとなっていた。Conventional devices, as described in Japanese Utility Model Application Publication No. 1-163451 and No. 1-163452, form an insulating film on the anode plate or a conductive film on the ground electrode plate to remove dust. Even if it gets stuck, the dust can be easily removed during cleaning.
上記従来技術は、粉塵が、陽極板及び接地極板に付着し
にくいため、集塵した粉塵の風圧による再飛散の問題や
、集塵した粉塵の保持の容量が少なく、洗浄の周期か短
くなってしまう問題があったＯ
また、第２図に示す従来の電極では樹脂膜８が簾いため
、−旦接地極板６に付着した塵埃１１は風力や振動なと
のため、接地極板から放れ、空気湊浄機吹出口へ流れて
行ってしまうという問題があった。With the above conventional technology, dust does not easily adhere to the anode plate and the ground electrode plate, so there are problems with the collected dust being re-dispersed due to wind pressure, the capacity for holding the collected dust is small, and the cleaning cycle is shortened. In addition, in the conventional electrode shown in Fig. 2, since the resin film 8 is a screen, the dust 11 that has adhered to the ground electrode plate 6 cannot be blown away from the ground electrode plate due to wind force or vibration. There was a problem in that the air flowed into the air outlet of the air purifier.
本発明は積極的に接地極板に粉塵を付着させ、集ｍ効率
の向上と粉塵保持容量のアップを図り、さらに粉塵の除
去は樹脂被膜こと両極板から除去する方式により粉塵除
去作業の容易化を図ることを目的とする。The present invention actively attaches dust to the ground electrode plate to improve m collection efficiency and increase the dust holding capacity, and also facilitates dust removal work by removing dust from the resin coating or both electrode plates. The purpose is to achieve this goal.
上記目的を達成するために、接地極板表面に樹脂層を形
成し、塵埃が静ｔｌｉＭ力により接地極板に付着する他
に、樹脂表面の粘着力により付着するようにしたもので
ある。さらに−旦付着した塵埃を放さず保持容量が向上
するので付着塵埃の除去周期が長くなるようにしたもの
である。In order to achieve the above object, a resin layer is formed on the surface of the ground electrode plate, so that dust adheres to the ground electrode plate not only by static tliM force but also by the adhesive force of the resin surface. Furthermore, the retention capacity is improved by not releasing the dust that has once adhered, so that the period for removing the adhered dust can be extended.
また、付着塵埃の除去作業は、接地極板表面の樹脂膜を
接地極板からはかすことにより容易にかつ完全に付着塵
埃が除去できる。Further, the attached dust can be easily and completely removed by removing the resin film on the surface of the ground electrode plate from the ground electrode plate.
樹脂膜は、機械的力、熱あるいは化学的力により極板か
らはかれ得る性質を有するものである。The resin film has a property that it can be peeled off from the electrode plate by mechanical force, heat, or chemical force.
電気集塵器に流入してくる空気中の塵埃に、荷電部のコ
ロナ放電により、陽電荷が与えられる。The dust in the air flowing into the electrostatic precipitator is given a positive charge by the corona discharge of the charged part.
陽電荷を与えられた塵埃は、集塵部に流れ、そこの陽電
荷と接地電極間に発生する電界の力により接地電極に引
かれ付着する。−旦付着した塵埃は接地電極表面の樹脂
膜の粘着力と、前述の静電気力によって、風圧、振動な
どの力では容易に放れなくなる。The positively charged dust flows to the dust collecting section, and is attracted to and adheres to the ground electrode by the force of the electric field generated between the positive charges there and the ground electrode. - Once attached, dust cannot be easily released by forces such as wind pressure or vibration due to the adhesive force of the resin film on the surface of the ground electrode and the aforementioned electrostatic force.
また、荷電部にて十分に陽電荷が与えられなかった塵埃
についても、空気流の乱れやブラウン運動により接地極
板；こ到達すると、樹脂膜の粘着力により１寸着し・、
前述の場合と同様容易に放れなくなる。In addition, dust that has not been given a sufficient positive charge at the charged section will arrive at the ground electrode plate due to airflow turbulence or Brownian motion, and will adhere to the ground electrode plate by an inch due to the adhesive force of the resin film.
As in the previous case, it will not be easy to release it.
二のようにして集塵効率の向上と粉塵保持用量の向上が
図れる。また粉塵保持容量の向上により付着塵埃の除去
周期か長くなりメンテナンスの手間が省ける。In the second way, it is possible to improve the dust collection efficiency and the amount of dust retained. In addition, the improved dust holding capacity lengthens the removal cycle for adhering dust, reducing maintenance effort.
さらに、樹脂膜は接地極板から、機械的力、熱゛あるい
は化学力により容易にはがれ得る性質を有している。し
たがって樹脂膜をはがすことにより、樹脂膜に付着の塵
埃も除去でき、集塵電板の再生が容易に行なうことがで
きる。Furthermore, the resin film has a property that it can be easily peeled off from the ground electrode plate by mechanical force, heat, or chemical force. Therefore, by peeling off the resin film, dust adhering to the resin film can also be removed, and the dust collecting plate can be easily recycled.
