Description

本発明は、空調機の上流側に設置し、雰囲気中のオイルミストを含む塵埃を捕集する電気集塵装置に関するものである。 TECHNICAL FIELD The present invention relates to an electrostatic precipitator installed upstream of an air conditioner to collect dust including oil mist in the atmosphere.

空調機の上流側に設置して、空調機による気流を利用して工場内のオイルミストを含む塵埃を捕集する電気集塵装置が広く使用されている。この電気集塵装置は、上流側で空気に含まれる塵埃に電荷を付与する帯電部と、下流側で帯電した塵埃を捕集する集塵部とを有する構造とされている。 2. Description of the Related Art An electrostatic precipitator installed upstream of an air conditioner to collect dust including oil mist in a factory using airflow from the air conditioner is widely used. This electrostatic precipitator has a structure including a charging section that charges dust contained in the air on the upstream side and a dust collecting section that collects the charged dust on the downstream side.

工場の大きさ等により空調機のサイズは様々であり、空調機のサイズに合わせて電気集塵装置を製造する場合には、帯電部及び集塵部を大型化する等の製造に手間を要する。 The size of the air conditioner varies depending on the size of the factory, etc., and when manufacturing the electrostatic precipitator according to the size of the air conditioner, it takes time and effort to manufacture, such as enlarging the charging part and the dust collection part. .

また、特許文献１に開示された電気集塵装置のように、通常では帯電部や集塵部のメンテナンス作業を行う際に、帯電部や集塵部を装置本体部に出し入れする方向は、装置内を流れる空気の気流方向に対する直交面の水平方向、つまり装置の側面から帯電部や集塵部を引き出してメンテナンス作業を行っている。 Further, like the electrostatic precipitator disclosed in Japanese Patent Laid-Open No. 2002-200001, when performing maintenance work on the charging section and the dust collecting section, the direction in which the charging section and the dust collecting section are inserted into and removed from the main body of the apparatus is usually different. Maintenance work is performed by pulling out the charging section and dust collection section from the horizontal direction of the plane perpendicular to the airflow direction of the air flowing inside, that is, from the side of the device.

本発明を図示の実施例に基づいて詳細に説明する。
図１は電気集塵装置１０を左側から見た状態の分解斜視図であり、図２は電気集塵装置１０に収容される塵埃捕集部を右側から見た際の分解斜視図である。電気集塵装置１０は前面が開放された箱状の筐体部２０と、筐体部２０の中空部２１に収容され、塵埃を含む空気が通過する塵埃捕集部３０とから構成されている。電気集塵装置１０は電気集塵システムを構成する最小単位のユニット体であり、例えば縦横７５０ｍｍ、奥行き６５０ｍｍ程度の直方体状とされている。電気集塵装置１０を縦横に連結することで、任意の面積の吸気口を有する電気集塵システムを製造することが可能である。 The present invention will be described in detail based on the illustrated embodiments.
FIG. 1 is an exploded perspective view of the electrostatic precipitator 10 as seen from the left side, and FIG. 2 is an exploded perspective view of the dust collecting portion accommodated in the electrostatic precipitator 10 as seen from the right side. The electric dust collector 10 is composed of a box-shaped casing 20 with an open front surface, and a dust collector 30 which is housed in a hollow part 21 of the casing 20 and through which air containing dust passes. . The electrostatic precipitator 10 is a unit body of the minimum unit constituting the electrostatic precipitator system, and has, for example, a rectangular parallelepiped shape of about 750 mm in length and width and 650 mm in depth. By connecting the electrostatic precipitators 10 vertically and horizontally, it is possible to manufacture an electrostatic precipitator system having an air intake of any area.

筐体部２０の前面には、塵埃捕集部３０を収容するための中空部２１が、略直方体状に開口して形成されている。中空部２１の開口サイズは、クリアランスを確保するために塵埃捕集部３０のサイズよりも若干大きくされている。中空部２１に塵埃捕集部３０を挿入すると、中空部２１の開口の周縁部には僅かな空隙部が生じて、塵埃捕集部３０の収容が円滑となる。 A hollow portion 21 for accommodating the dust collecting portion 30 is formed on the front surface of the housing portion 20 so as to have a substantially rectangular parallelepiped shape. The opening size of the hollow portion 21 is made slightly larger than the size of the dust collecting portion 30 in order to ensure clearance. When the dust collecting portion 30 is inserted into the hollow portion 21, a slight gap is formed in the periphery of the opening of the hollow portion 21, and the dust collecting portion 30 can be accommodated smoothly.

筐体部２０の中空部２１の底面２１ａは、前面側が低くなるように若干傾斜している。 The bottom surface 21a of the hollow portion 21 of the housing portion 20 is slightly inclined so that the front side is lower.

この傾斜に沿って底面２１ａの右側に仕切板部２２が配置されている。仕切板部２２によって底面２１ａが仕切られて、中空部２１の右側面２１ｂと仕切板部２２の間には、オイル回収路２２ａが形成されている。なお、仕切板部２２は省略することも可能である。 A partition plate portion 22 is arranged on the right side of the bottom surface 21a along this inclination. The bottom surface 21 a is partitioned by the partition plate portion 22 , and an oil recovery path 22 a is formed between the right side surface 21 b of the hollow portion 21 and the partition plate portion 22 . Note that the partition plate portion 22 may be omitted.

底面２１aの傾斜は、中空部２１の前面の枠部２１ｃの下辺部に向かって形成されており、枠部２１ｃの下辺部には後述する排出管に接続されるオイル排出口２３が突出している。つまり、塵埃捕集部３０から滴り落ちたオイルは、前方に若干傾斜している底面２１aを前端に向かって流れ、前端に設けられたオイル排出口２３から外部に排出される構造となっている。なお、オイル排出口２３は排出管に接続されていない場合には、キャップ等の封止材により閉塞されている。 The bottom surface 21a is inclined toward the lower side of a frame portion 21c on the front surface of the hollow portion 21, and an oil discharge port 23 connected to a discharge pipe, which will be described later, protrudes from the lower side of the frame portion 21c. . In other words, the oil dripping from the dust collector 30 flows toward the front end of the bottom surface 21a which is slightly inclined forward, and is discharged to the outside from the oil discharge port 23 provided at the front end. . When the oil discharge port 23 is not connected to the discharge pipe, the oil discharge port 23 is closed with a sealing member such as a cap.

また底面２１ａには、オイル流出孔２２ｂが設けられている。このオイル流出孔２２ｂの直上の位置には、筐体部２０の中空部２１の頂面２１ｄにオイル流入孔２４が設けられている。縦方向に電気集塵装置１０を連結する際には、底面２１ａから下方に突出するオイル流出孔２２ｂの下端円環部をオイル流入孔２４の内側に嵌め込んで、上段の筐体部２０の底面と下段の筐体部２０の天面を隙間なく密着させて、接続できる構造とされている。 An oil outflow hole 22b is provided in the bottom surface 21a. An oil inflow hole 24 is provided in the top surface 21d of the hollow portion 21 of the housing portion 20 at a position directly above the oil outflow hole 22b. When connecting the electrostatic precipitator 10 in the vertical direction, the lower annular portion of the oil outflow hole 22b protruding downward from the bottom surface 21a is fitted inside the oil inflow hole 24, and the upper housing portion 20 is connected. The structure is such that the bottom surface and the top surface of the lower housing part 20 can be brought into close contact with each other without a gap, and can be connected.

なお、オイル流出孔２２ｂ、オイル流入孔２４は、他の電気集塵装置１０のオイル流出孔２２ｂ、オイル流入孔２４と接続されていない場合には、キャップ等の封止材で閉塞しておく。例えば、縦方向に電気集塵装置１０を３個連結する際には、上段の電気集塵装置１０のオイル流入孔２４を封止材で閉塞し、上段の電気集塵装置１０のオイル流出孔２２ｂを中段の電気集塵装置１０のオイル流入孔２４に接続する。中段の電気集塵装置１０のオイル流出孔２２ｂを、下段のオイル流入孔２４に接続し、下段の電気集塵装置１０のオイル流出孔２２ｂを封止材により閉塞する。 When the oil outflow hole 22b and the oil inflow hole 24 are not connected to the oil outflow hole 22b and the oil inflow hole 24 of the other electrostatic precipitator 10, the oil outflow hole 22b and the oil inflow hole 24 are closed with a sealing material such as a cap. . For example, when connecting three electrostatic precipitators 10 in the vertical direction, the oil inflow hole 24 of the upper electrostatic precipitator 10 is closed with a sealing material, and the oil outflow hole of the upper electrostatic precipitator 10 is closed. 22b is connected to the oil inlet hole 24 of the electrostatic precipitator 10 in the middle stage. The oil outflow hole 22b of the middle electric dust collector 10 is connected to the lower oil inflow hole 24, and the oil outflow hole 22b of the lower electric dust collector 10 is closed with a sealing material.

このように、縦方向に連結した電気集塵装置１０のオイル流出孔２２ｂ、オイル流入孔２４を相互に接続することによって、それぞれの電気集塵装置１０で捕集されるオイルを最下段の電気集塵装置１０に集約することが可能である。そして、最下段の電気集塵装置１０のオイル排出口２３から後述する排出管に排出することができる。 By connecting the oil outflow holes 22b and the oil inflow holes 24 of the electrostatic precipitators 10 connected in the vertical direction to each other in this way, the oil collected by each electrostatic precipitator 10 is It is possible to concentrate on the dust collector 10 . Then, the oil can be discharged from the oil discharge port 23 of the lowermost electric dust collector 10 to a discharge pipe described later.

また、中空部２１の底面２１ａ上には、塵埃捕集部３０が収容し易いように、摺動時の滑りを良くする左右一対の合成樹脂等から成る摺動板部２５が、筐体部２０の前面から背面方向に載置されている。中空部２１の右側面２１ｂの内側には、前面から背面に向かって、塵埃捕集部３０の摺動方向を案内するレール状の突条部２６が水平方向に沿って配置されている。この突条部２６は、塵埃捕集部３０の後述する切欠溝と噛み合わせることで、塵埃捕集部３０の取り付け方向を間違えないように案内する。 Further, on the bottom surface 21a of the hollow portion 21, a pair of right and left sliding plates 25 made of synthetic resin or the like, which improves sliding during sliding, is provided so that the dust collecting portion 30 can be easily accommodated. 20 is placed from the front to the back. Inside the right side surface 21b of the hollow portion 21, a rail-shaped ridge portion 26 for guiding the sliding direction of the dust collecting portion 30 is arranged along the horizontal direction from the front surface to the rear surface. The ridges 26 are engaged with later-described notch grooves of the dust collecting portion 30 to guide the mounting direction of the dust collecting portion 30 so as not to be mistaken.

中空部２１の前面を囲む周縁部２１ｅの上下縁の裏面側には図示しない上溝部と下溝部２７が設けられており、上溝部及び下溝部２７の両端から直交する個所に設置面部２８が設けられている。後述する塵埃捕集部３０のフィルタ部３１の上下の縁部を上下に移動させて上溝部及び下溝部２７に嵌合させ、左右の縁部の裏面を設置面部２８に当接させることで、フィルタ部３１を中空部２１の前面に対して容易に取り付けることができる。 An upper groove portion and a lower groove portion 27 (not shown) are provided on the back side of the upper and lower edges of the peripheral edge portion 21e surrounding the front surface of the hollow portion 21, and a mounting surface portion 28 is provided at a position perpendicular to both ends of the upper groove portion and the lower groove portion 27. It is By vertically moving the upper and lower edges of the filter portion 31 of the dust collecting portion 30 to be described later and fitting them into the upper groove portion and the lower groove portion 27, and by bringing the back surfaces of the left and right edges into contact with the installation surface portion 28, The filter part 31 can be easily attached to the front surface of the hollow part 21 .

中空部２１の右上端には、図１に点線で示した給電部２９が配置されており、この給電部２９には塵埃捕集部３０の収納方向に沿った主電力架２９ａに板ばね等の塵埃捕集部３０の接点部への接触構造を設けた複数個の接点部２９ｂが並列に配置されている。 A power feeder 29 indicated by a dotted line in FIG. A plurality of contact portions 29b provided with a contact structure for the contact portions of the dust collecting portion 30 are arranged in parallel.

これらの接点部２９ｂが、後述する塵埃捕集部３０の各部に設けた接点部に接触することで塵埃捕集部３０の各部に電力が供給される。 Electric power is supplied to each part of the dust collecting part 30 by contacting these contact parts 29b with contact parts provided in each part of the dust collecting part 30, which will be described later.

また、図示は省略しているが、筐体部２０の背面は空気の通過可能な、例えば多孔質やメッシュ状又は中央に大きく孔を開けた板面体とされ、中空部２１に収容される塵埃捕集部３０の挿入に伴う摺動を、所定位置で止めるストッパ部として機能している。 Although not shown, the rear surface of the housing 20 is made of, for example, a porous or mesh-like plate or a plate with a large hole in the center through which air can pass. It functions as a stopper portion that stops the sliding accompanying the insertion of the collecting portion 30 at a predetermined position.

塵埃捕集部３０は、フィルタ部３１と、荷電部３２と、２個の捕集部３３とから構成され、中空部２１に収納する際に一体化される。筐体部２０の前面からフィルタ部３１、荷電部３２、２個の捕集部３３の順で、中空部２１に格納されることになる。図１では２個の捕集部３３を格納可能としているが、１個又は３個以上の捕集部３３を格納可能としてもよい。なお、捕集部３３の増加に伴い集塵効率は向上する。 The dust collecting portion 30 is composed of a filter portion 31, a charging portion 32, and two collecting portions 33, which are integrated when housed in the hollow portion 21. As shown in FIG. The filter section 31 , charging section 32 , and two collection sections 33 are stored in the hollow section 21 in this order from the front surface of the housing section 20 . Although two collection units 33 are storable in FIG. 1, one or three or more collection units 33 may be storable. It should be noted that the dust collection efficiency is improved as the number of collecting portions 33 is increased.

フィルタ部３１は、矩形環状の枠体３１ａと、この枠体３１ａの内側に取り付けられた金属等の網状体３１ｂと、網状体３１ｂ間に固定された不織布等から成るフィルタ材３１ｃとから構成されている。枠体３１ａの上縁には、段差部３１ｄが形成されている。中空部２１内の上述の上溝部に、枠体３１ａの上端である段差部３１ｄを斜め方向から挿入した後に、枠体３１ａの下端を下溝部２７に嵌合させて、左右端を周縁部２１ｅの左右縁の設置面部２８に当接させることで、筐体部２０の中空部２１の前面にフィルタ部３１を取り付ける。 The filter portion 31 is composed of a rectangular annular frame 31a, a mesh 31b made of metal or the like attached inside the frame 31a, and a filter material 31c made of nonwoven fabric or the like fixed between the mesh 31b. ing. A stepped portion 31d is formed on the upper edge of the frame 31a. After the stepped portion 31d, which is the upper end of the frame 31a, is inserted obliquely into the above-described upper groove portion in the hollow portion 21, the lower end of the frame 31a is fitted into the lower groove portion 27, and the left and right ends are fitted into the peripheral edge portions 21e. The filter portion 31 is attached to the front surface of the hollow portion 21 of the housing portion 20 by abutting on the installation surface portions 28 on the left and right edges of the housing portion 20 .

荷電部３２は、図示しない高電圧を印加された複数のイオン化線と、これらのイオン化線を挟むように配置され、気流の流路に対して平行に配置された多数の対向電極板３２ａとを有している。そして、荷電部３２の内部を通過する空気内の塵埃に対して、イオン化線と対向電極板３２ａの間にコロナ放電を発生させて、塵埃をプラスに荷電してイオン化させる。 The charging section 32 includes a plurality of ionization lines (not shown) to which a high voltage is applied, and a large number of counter electrode plates 32a arranged so as to sandwich the ionization lines and parallel to the flow path of the airflow. have. Then, a corona discharge is generated between the ionizing wire and the counter electrode plate 32a for the dust in the air passing through the inside of the charging section 32, and the dust is positively charged and ionized.

捕集部３３は、高電圧側に接続された非集塵電極板と、アース側に接続された集塵電極板とから成り、これらは交互に配置され、電圧印加ないし集塵を行う多数の電極板３３ａが、気流の流路に平行に配置されている。荷電部３２によりイオン化した塵埃を、電極板３３ａの集塵電極板に集塵させることで捕集する。 The collecting part 33 consists of a non-collecting electrode plate connected to the high voltage side and a collecting electrode plate connected to the ground side. An electrode plate 33a is arranged in parallel with the flow path of the airflow. The dust ionized by the charging section 32 is collected by collecting the dust on the dust collection electrode plate of the electrode plate 33a.

捕集する塵埃はオイル成分を含んでおり、集塵電極板に付着したオイル成分が、集塵電極板から底面に滴り落ちることになる。 Dust to be collected contains an oil component, and the oil component adhering to the dust collection electrode plate drips from the dust collection electrode plate to the bottom surface.

また、捕集部３３の前面及び背面には、他の捕集部３３との当接時に、他の捕集部３３のねじやリベットの頭が接触する個所に、予めねじやリベットの頭の直径より大きい穴部が設けられている。そして、捕集部３３同士が当接した際に、ねじやリベットの頭が穴部に挿入されることで、捕集部３３同士が密着可能とされ、捕集部３３に隙間が発生することを防止している。 Further, on the front surface and the back surface of the collecting portion 33, screw or rivet heads are preliminarily attached to the portions where the screws or rivet heads of the other collecting portion 33 come into contact when the other collecting portion 33 abuts thereon. A larger diameter hole is provided. When the collecting portions 33 come into contact with each other, the heads of the screws or rivets are inserted into the holes, so that the collecting portions 33 can be brought into close contact with each other, and a gap is generated between the collecting portions 33. prevent

なお、上述の穴部は荷電部３２の背面にも同様に設けられており、荷電部３２及び捕集部３３を密着可能としている。従って、塵埃捕集部３０の荷電部３２と捕集部３３、及び捕集部３３同士は、気流が外部にリークすることなく密着されているので、塵埃捕集部３０には外部とは独立した気流の流路が形成される。 The above-described hole is also provided on the rear surface of the charging section 32, so that the charging section 32 and the collection section 33 can be brought into close contact with each other. Therefore, the charging portion 32 and the collecting portion 33 of the dust collecting portion 30, and the collecting portions 33 are in close contact with each other without airflow leaking to the outside. An air flow path is formed.

荷電部３２及び捕集部３３の右側面には、図２に示すように切欠溝３２ｂ、３３ｂが設けられており、前述の突条部２６と切欠溝３２ｂ、３３ｂとが噛み合うので、荷電部３２及び捕集部３３を一体化させて塵埃捕集部３０として中空部２１内に格納する際に、取付方向を間違えることなく行うことができる。なお、中空部２１に切欠溝を設け、荷電部３２及び捕集部３３に突条部を設けるようにしてもよい。 Notch grooves 32b and 33b are provided on the right sides of the charging portion 32 and the collecting portion 33 as shown in FIG. 32 and the collecting part 33 can be integrated and stored in the hollow part 21 as the dust collecting part 30 without making a mistake in the mounting direction. Note that a notch groove may be provided in the hollow portion 21 and a ridge portion may be provided in the charging portion 32 and the collecting portion 33 .

荷電部３２及び捕集部３３の上面端部には、接点部３２ｃ、３３ｃが設けられている。前述の板ばね等の接触構造を設けた給電部２９の接点部２９ｂが接点部３２ｃ、３３ｃに接触した際に、板ばねの押圧力により確実に通電され、後述する電源部から荷電部３２及び捕集部３３に電力が供給される。 Contact portions 32 c and 33 c are provided at the upper surface end portions of the charging portion 32 and the collecting portion 33 . When the contact portion 29b of the power supply portion 29 provided with the contact structure such as the leaf spring described above contacts the contact portions 32c and 33c, the pressing force of the leaf spring reliably energizes the power supply portion 32 and the charging portion 32 from the power supply portion described later. Power is supplied to the collection unit 33 .

中空部２１内に塵埃捕集部３０を格納する場合は、捕集部３３、荷電部３２の順に、摺動板部２５上を摺動させながら押し込んだ後に、フィルタ部３１を中空部２１の前面に取り付ける。フィルタ部３１は荷電部３２及び捕集部３３を若干、押圧した状態で周縁部２１ｅに取り付けることになり、この押圧力によって荷電部３２と捕集部３３とが密着し、各部間から塵埃捕集部３０を流れる空気が外部に漏れることはない。 When the dust collecting portion 30 is housed in the hollow portion 21 , the collecting portion 33 and the charging portion 32 are pushed in in this order while being slid on the sliding plate portion 25 , and then the filter portion 31 is inserted into the hollow portion 21 . Install on the front. The filter portion 31 is attached to the peripheral edge portion 21e with the charging portion 32 and the collecting portion 33 pressed slightly. The air flowing through the collecting portion 30 does not leak to the outside.

従って、中空部２１内に塵埃捕集部３０を格納した際に、荷電部３２及び捕集部３３の外面と頂面２１ｄの内面との間には、給電部２９を配置可能なクリアランスによる空隙部が存在するが、荷電部３２及び捕集部３３が一体化することで、塵埃捕集部３０の流路から空隙部を隔離することができる。また、フィルタ部３１が周縁部２１ｅに取り付けられているので、空隙部を外気からも隔離することができる。従って、空隙部内は電気集塵装置１０の手前の外気や塵埃捕集部３０を流れる気流によって汚染されにくいので、メンテナンス作業時に清掃等が容易となる。 Therefore, when the dust collecting portion 30 is housed in the hollow portion 21, there is a gap formed by a clearance that allows the feeding portion 29 to be arranged between the outer surfaces of the charging portion 32 and the collecting portion 33 and the inner surface of the top surface 21d. However, by integrating the charging section 32 and the collecting section 33 , the air gap can be isolated from the flow path of the dust collecting section 30 . Moreover, since the filter portion 31 is attached to the peripheral edge portion 21e, the gap can be isolated from the outside air. Therefore, the inside of the gap is less likely to be contaminated by the outside air in front of the electrostatic precipitator 10 or the airflow flowing through the dust collecting section 30, so that cleaning is facilitated during maintenance work.

中空部２１内から塵埃捕集部３０を取り外す場合は、フィルタ部３１を中空部２１の前面の上溝部及び下溝部２７から外して、荷電部３２及び捕集部３３を引き出す。引き出した後に、荷電部３２及び捕集部３３の点検、保守、清掃等を行うことができる。 When removing the dust collecting part 30 from the inside of the hollow part 21, the filter part 31 is removed from the upper groove part and the lower groove part 27 on the front surface of the hollow part 21, and the charging part 32 and the collecting part 33 are pulled out. After being pulled out, the charge section 32 and the collection section 33 can be inspected, maintained, cleaned, and the like.

Link. Then, a connection pipe 41 is arranged to connect the oil discharge ports 23 provided in the housing portion 20 of the electric dust collector 10 in the lower stage, and the collected oil is discharged from the connection pipe 41 connected in the horizontal direction 1 . A main discharge pipe 42 is connected to the connecting pipe 41 . This discharge pipe 42 is arranged so as to pass through the inside of the base portion 40, and is collected by each electrostatic precipitator 10, and the oil discharged from the side surface of the base portion 40 is stored in an oil reservoir installed separately from the apparatus. Stored in unit 43 .

３個の基台部４０の上面に下段の３個の電気集塵装置１０がそれぞれ載置され、各基台部４０にボルト等で固定される。下段の３個の電気集塵装置１０は、側面同士が隙間なく当接し、横方向に並置される。下段の３個の電気集塵装置１０の各筐体部２０に設けられたオイル排出口２３に、接続管４１が接続される。下段の３個の電気集塵装置１０の各底面に設けられたオイル流出孔２２ｂは、使用されないのでキャップ等で閉塞される。 The lower three electrostatic precipitators 10 are respectively placed on the upper surfaces of the three bases 40 and fixed to the respective bases 40 with bolts or the like. The three electrostatic precipitators 10 in the lower row are arranged side by side in the lateral direction with their side surfaces in contact with each other without gaps. A connection pipe 41 is connected to the oil discharge port 23 provided in each housing portion 20 of the three electric dust collectors 10 in the lower stage. The oil outflow holes 22b provided in the bottom surfaces of the lower three electrostatic precipitators 10 are closed with caps or the like because they are not used.

下段の３個の電気集塵装置１０の上面に中段の３個の電気集塵装置１０がそれぞれ載置され、ボルト等で固定される。その結果、中段の３個の電気集塵装置１０は、側面同士が隙間なく当接し、横方向に並置される。その際に、下段の３個の電気集塵装置１０の各頂面に設けられたオイル流入孔２４の内側面に、中段の３個の電気集塵装置１０の各底面に設けられたオイル流出孔２２ｂがそれぞれ嵌め込まれ、装置間の縦方向のオイル排出経路が接続される。 The three electric dust collectors 10 in the middle stage are placed on the upper surfaces of the three electric dust collectors 10 in the lower stage and fixed with bolts or the like. As a result, the side surfaces of the three electric dust collectors 10 in the middle row are in contact with each other without gaps, and are arranged side by side in the horizontal direction. At that time, the inner surface of the oil inflow hole 24 provided on each top surface of the three electric dust collectors 10 in the lower stage and the oil outflow provided on each bottom surface of the three electric dust collectors 10 in the middle stage The holes 22b are fitted respectively to connect the longitudinal oil discharge paths between the devices.

同様にして中段の３個の電気集塵装置１０の上面に上段の３個の電気集塵装置１０がそれぞれ載置され、ボルト等で固定される。その結果、上段の３個の電気集塵装置１０は、側面同士が隙間なく当接し、横方向に並置される。その際に、中段の３個の電気集塵装置１０の各頂面に設けられたオイル流入孔２４に、上段の３個の電気集塵装置１０の各底面に設けられたオイル流出孔２２ｂがそれぞれ嵌め込まれ、装置間の縦方向のオイル排出経路が接続される。また、上段の３個の電気集塵装置１０の各頂面に設けられたオイル流入孔２４は、使用されないのでキャップ等で閉塞される。 Similarly, the upper three electrostatic precipitators 10 are placed on the upper surfaces of the middle three electrostatic precipitators 10 and fixed with bolts or the like. As a result, the side surfaces of the upper three electrostatic precipitators 10 are in contact with each other without gaps, and are arranged side by side in the horizontal direction. At that time, the oil inflow holes 24 provided in the top surfaces of the three electric dust collectors 10 in the middle stage and the oil outflow holes 22b provided in the bottom surfaces of the three electric dust collectors 10 in the upper stage are connected. They are fitted into each other and connect the longitudinal oil drain paths between the devices. Also, the oil inlet holes 24 provided on the top surfaces of the upper three electrostatic precipitators 10 are closed with caps or the like because they are not used.

このように、縦方向に３段の電気集塵装置１０を積載すると、上段及び中段の電気集塵装置１０で捕集された塵埃に含まれるオイルミストが液化してオイルとなり、オイル流出孔２２ｂ及びオイル流入孔２４を介して下段の電気集塵装置１０に滴下されて溜まる。下段の電気集塵装置１０で捕集された塵埃に含まれるオイルミストが液化したオイルと合わせて、下段の電気集塵装置１０に溜まったオイルは、オイル排出口２３から接続管４１、排出管４２を通ってオイル貯留部４３に排出される。 In this way, when the three stages of the electrostatic precipitator 10 are vertically stacked, the oil mist contained in the dust collected by the upper and middle stages of the electrostatic precipitator 10 is liquefied to become oil, and the oil outflow hole 22b. Then, the oil drips and accumulates in the lower electric dust collector 10 through the oil inflow hole 24 . The oil accumulated in the lower electrostatic precipitator 10 together with the liquefied oil of the oil mist contained in the dust collected by the lower electrostatic precipitator 10 is discharged from the oil outlet 23 to the connecting pipe 41 and the discharge pipe. 42 to the oil reservoir 43 .

電気集塵システムの最右列の電気集塵装置１０の右側面２１ｂの外側には、図３に示すように、３個の駆動監視部５０がそれぞれボルト等で固定されて取り付けられている。電気集塵システムの右上部に配置された電気集塵装置１０の頂面２１ｄ上には、制御部６０が取り付けられている。 As shown in FIG. 3, three drive monitoring units 50 are fixed with bolts or the like to the outside of the right side surface 21b of the rightmost electrostatic precipitator 10 in the electrostatic precipitator system. A control unit 60 is attached on the top surface 21d of the electrostatic precipitator 10 arranged in the upper right part of the electrostatic precipitator system.

駆動監視部５０は、電気集塵装置１０に電力を供給する電源部と、電気集塵装置１０の塵埃捕集部３０の動作状態をチェックする監視部とから構成されている。３×３に連結された電気集塵装置１０の各段に対して、１個の駆動監視部５０が配置されている。下段の駆動監視部５０の電源部は、図示しない配線を介して、下段の３個の電気集塵装置１０の給電部２９に並列に接続されており、塵埃捕集部３０を駆動する電力を供給している。中段及び上段の駆動監視部５０の電源部についても、同様に図示しない配線を介して、中段及び上段の各３個の電気集塵装置１０に対して電力を供給している。 The drive monitoring unit 50 includes a power supply unit that supplies electric power to the electrostatic precipitator 10 and a monitoring unit that checks the operating state of the dust collecting unit 30 of the electrostatic precipitator 10 . One drive monitoring unit 50 is arranged for each stage of the electrostatic precipitator 10 connected in 3×3.

The power supply units of the drive monitoring units 50 in the middle and upper stages similarly supply power to the three electric dust collectors 10 in the middle and upper stages via wiring (not shown).

また、下段の駆動監視部５０の監視部は、図示しない配線を介して下段の３個の電気集塵装置１０の塵埃捕集部３０の荷電部３２、捕集部３３にそれぞれ接続されており、荷電部３２及び捕集部３３の動作状態を監視している。中段及び上段の駆動監視部５０の監視部についても、同様に図示しない配線を介して、中段及び上段の各３個の電気集塵装置１０の動作状態を監視している。 The monitoring unit of the drive monitoring unit 50 in the lower stage is connected to the charging unit 32 and the collecting unit 33 of the dust collecting units 30 of the three electric dust collectors 10 in the lower stage via wiring (not shown), respectively. , the charging unit 32 and the collecting unit 33 are monitored. The monitoring units of the drive monitoring units 50 in the middle and upper stages similarly monitor the operating states of the three electrostatic precipitators 10 in each of the middle and upper stages via wiring (not shown).

３個の駆動監視部５０は、それぞれの信号送受信線５１を介して、制御部６０と接続されている。下段の駆動監視部５０は、監視対象である下段の３個の電気集塵装置１０の駆動状況、特に塵埃捕集部３０の荷電部３２及び捕集部３３の動作状況を、制御部６０に送信する。中段及び上段の駆動監視部５０も、同様にして監視対象である中段及び上段の各３個の電気集塵装置１０の駆動状況を、制御部６０に送信する。また、３個の駆動監視部５０は、後述するように制御部６０から信号送受信線５１を介して制御指示の信号を受信して、制御指示に従って監視対象の電気集塵装置１０への電力供給を制御する。 The three drive monitoring units 50 are connected to the control unit 60 via respective signal transmission/reception lines 51 . The drive monitoring unit 50 in the lower stage notifies the control unit 60 of the driving conditions of the three electric dust collectors 10 in the lower row to be monitored, particularly the operating conditions of the charging unit 32 and the collecting unit 33 of the dust collecting unit 30. Send. The driving monitoring units 50 in the middle and upper stages also transmit the driving states of the three electrostatic precipitators 10 to be monitored in the middle and upper stages to the control unit 60 in the same manner. In addition, the three drive monitoring units 50 receive a control instruction signal from the control unit 60 via the signal transmission/reception line 51 as described later, and supply power to the electric dust collector 10 to be monitored according to the control instruction. to control.

制御部６０は、各種の表示操作等を行う操作部６１と、駆動監視部５０を介して収集される各電気集塵装置１０の駆動状態等を表示するモニタ部６２と、駆動状態をまとめて表示させる代表灯部６３とから構成されている。操作部６１、モニタ部６２、代表灯部６３は、電気集塵システムの右側面に向くように配置されており、電気集塵装置１０を縦に積み重ねて、高所に制御部６０を設置する場合でも操作可能とするため、各部が斜め下側に向くように配置されている。制御部６０及び駆動監視部５０は、図３に示す設置位置に対し左右対称の位置に配置されてもよい。 The control unit 60 includes an operation unit 61 for performing various display operations and the like, a monitor unit 62 for displaying the driving state of each electrostatic precipitator 10 collected via the driving monitoring unit 50, and the driving state collectively. It is composed of a representative lamp portion 63 to be displayed. The operation part 61, the monitor part 62, and the representative lamp part 63 are arranged to face the right side of the electrostatic precipitator system, and the electrostatic precipitator 10 is stacked vertically, and the control part 60 is installed at a high place. Each part is arranged so that it faces diagonally downward so that it can be operated even in the case of The control unit 60 and the drive monitoring unit 50 may be arranged at symmetrical positions with respect to the installation position shown in FIG.

On/off control of the power supply of the electrostatic precipitator 10 can be performed. The content of the control instruction is transmitted to the drive monitoring unit 50 that monitors the electrostatic precipitator 10 to be operated via the signal transmission/reception line 51 . A touch panel type may be adopted as the monitor unit 62 .

このように実施例の電気集塵装置によれば、縦及び横方向に複数個の電気集塵装置１０を連結して、容易に任意のサイズの電気集塵システムを組み上げることができる。上述の実施例では、９個の電気集塵装置１０を３×３に配置した電気集塵システムを示しているが、縦及び横方向に配置する電気集塵装置１０の個数は、電気集塵システムの背面側に設置する空調機のサイズに合わせて、適宜に変更できる。 Thus, according to the electrostatic precipitator of the embodiment, a plurality of electrostatic precipitators 10 can be connected in the vertical and horizontal directions to easily build up an electrostatic precipitator system of any size. In the above-described embodiment, an electrostatic precipitator system in which nine electrostatic precipitators 10 are arranged in 3×3 is shown, but the number of electrostatic precipitators 10 arranged in the vertical and horizontal directions It can be changed as appropriate according to the size of the air conditioner installed on the back side of the system.

また、例えば空調機の形状が矩形状ではなく、特殊な形状をしている場合には、その形状に合わせて使用されない部分の筐体部２０には電気集塵装置１０を格納せずに、中空部２１の前面の枠部２１ｃに開口を閉塞する閉鎖板を取り付けることができる。電気集塵システムを構成する複数個の電気集塵装置１０の一部に、突然に塵埃捕集部３０の故障が発生した場合にも、故障している電気集塵装置１０の塵埃捕集部３０のみを筐体部２０から取り出して、同様にして中空部２１の前面の枠部２１ｃに開口を閉塞する閉鎖板を取り付けることができる。従って、故障により停止した電気集塵装置１０から空調機内に汚染された空気が流れ込むことはなく、継続して電気集塵システムと空調機を運転させることができる。なお、閉鎖板の外形はフィルタ部３１と同一であり、全面が板状とされている。 Further, for example, if the shape of the air conditioner is not rectangular but has a special shape, the electric dust collector 10 is not stored in the unused portion of the housing 20 according to the shape. A closing plate that closes the opening can be attached to the frame portion 21 c on the front surface of the hollow portion 21 . Even if a sudden failure occurs in the dust collection unit 30 in some of the plurality of electric dust collectors 10 constituting the electric dust collection system, the dust collection unit of the malfunctioning electric dust collector 10 Only 30 can be taken out from the housing part 20, and a closing plate for closing the opening can be attached to the frame part 21c on the front surface of the hollow part 21 in the same manner. Therefore, polluted air does not flow into the air conditioner from the electrostatic precipitator 10 stopped due to failure, and the electrostatic precipitator system and the air conditioner can be operated continuously. The outer shape of the closing plate is the same as that of the filter portion 31, and the entire surface is plate-like.

更に、空調機の風量の面内分布が大きい場合には、電気集塵システムを構成する複数個の電気集塵装置１０の中で、風量が大きい部分の電気集塵装置１０には捕集部３３が３個で構成された塵埃捕集部３０を格納し、風量が小さい部分の電気集塵装置１０には捕集部３３が１個で構成された塵埃捕集部３０を格納し、風量が平均的な値の部分の電気集塵装置１０には捕集部３３が２個で構成された塵埃捕集部３０を格納して、効率的に集塵効果を高める運用を行うこともできる。 Furthermore, when the in-plane distribution of the air volume of the air conditioner is large, the collection unit 33 accommodates the dust collecting unit 30 composed of three pieces, and the dust collecting unit 30 composed of one collecting unit 33 is housed in the electric dust collector 10 of the part where the air volume is small, and the air volume is The electrostatic precipitator 10 in the portion where is the average value can also be operated to efficiently enhance the dust collection effect by storing the dust collection unit 30 composed of two collection units 33. .

図３、図４に示す電気集塵システムの電気集塵装置１０の１個に、例えば電源異常等の故障が発生した場合には、制御部６０の代表灯部６３による点灯を確認した作業者は、モニタ部６２で異常が発生している電気集塵装置１０を把握する。また、異常が発生している電気集塵装置１０の電源は自動的にオフ状態とする制御が行われる。制御部６０は、この電源オフ指令信号を異常が発生している電気集塵装置１０を監視している駆動監視部５０に、信号送受信線５１を介して送信する。電源オフ指令信号を受信した駆動監視部５０は、直ちに異常が発生している電気集塵装置１０への電源供給を停止する。 3 and 4, when a failure such as a power failure occurs in one of the electrostatic precipitators 10, a worker who confirms lighting by the representative light unit 63 of the control unit 60 grasps the electrostatic precipitator 10 in which an abnormality has occurred in the monitor section 62 . Further, control is performed to automatically turn off the power supply of the electrostatic precipitator 10 in which an abnormality has occurred. The control unit 60 transmits this power-off command signal to the drive monitoring unit 50 that monitors the electrostatic precipitator 10 in which an abnormality has occurred via the signal transmission/reception line 51 . Upon receiving the power-off command signal, the drive monitoring unit 50 immediately stops power supply to the electrostatic precipitator 10 in which the abnormality has occurred.

異常が発生し、電源供給が停止された電気集塵装置１０は、作業者により修理を行うために、フィルタ部３１が筐体部２０から取り外され、一体化されている荷電部３２及び捕集部３３が筐体部２０から取り出される。装置の前面側から塵埃捕集部３０を取り出すことを可能とすることで、異常の発生している電気集塵装置１０のみに対して、対処することが可能である。従って、荷電部３２や捕集部３３の故障が原因の場合には、直ちに正常な荷電部３２や捕集部３３に交換することができ、短時間で修理を完了し、正常な運転状態に電気集塵システムを復帰させることができる。 In order to repair the electrostatic precipitator 10 in which an abnormality has occurred and the power supply has been stopped, the filter unit 31 is removed from the housing unit 20 and integrated charging unit 32 and collecting unit 31 are removed for repair by an operator. The portion 33 is removed from the housing portion 20 . By making it possible to take out the dust collecting part 30 from the front side of the device, it is possible to deal with only the electrostatic precipitator 10 in which an abnormality has occurred. Therefore, when the charge part 32 or the collection part 33 malfunctions, the charge part 32 or the collection part 33 can be immediately replaced with a normal charge part 32 or the collection part 33, the repair can be completed in a short time, and the normal operating state can be restored. The electrostatic precipitator system can be reactivated.

また、異常の原因が容易には判明せず、修理に時間を要する場合には、異常が発生している電気集塵装置１０から汚染された空気が、中空部２１を通って空調機に流れ込むのを防止するために、上述のフィルタ部３１に代えて、上述の閉鎖板を中空部２１の前面の枠部２１ｃに取り付けて開口を閉塞する。閉鎖板を取り付けることで、継続して電気集塵システムと空調機を運転させることが可能である。 In addition, when the cause of the abnormality is not easily identified and it takes time to repair, the contaminated air from the abnormal electrostatic precipitator 10 flows into the air conditioner through the hollow portion 21. In order to prevent this, instead of the filter portion 31, the above-described closing plate is attached to the frame portion 21c on the front surface of the hollow portion 21 to close the opening. By attaching the closing plate, it is possible to operate the electrostatic precipitator system and the air conditioner continuously.

図３、図４に示す電気集塵システムの定期メンテナンス作業を運転中に行う場合には、まず作業者は制御部６０のモニタ部６２に、電気集塵システムを構成する各電気集塵装置１０の駆動状態及び点検履歴等を表示して確認する。メンテナンス対象となる電気集塵装置１０は、モニタ部６２に表示した駆動状態及び点検履歴等から決定される。 When the regular maintenance work of the electrostatic precipitator system shown in FIGS. display and check the driving status and inspection history of the The electrostatic precipitator 10 to be maintained is determined based on the drive state and inspection history displayed on the monitor section 62 .

メンテナンス対象の電源供給が停止された電気集塵装置１０は、作業者によりフィルタ部３１が筐体部２０から取り外され、一体化されている荷電部３２及び捕集部３３が筐体部２０から取り出される。フィルタ部３１、荷電部３２、捕集部３３等の汚染や劣化の状況を確認して、必要であれば各部の清掃や正常品への交換を行う。 In the electrostatic precipitator 10 to be maintained, the power supply is stopped, the filter unit 31 is removed from the housing unit 20 by the operator, and the integrated charging unit 32 and collection unit 33 are removed from the housing unit 20. taken out. The state of contamination and deterioration of the filter section 31, charging section 32, collection section 33, etc. is checked, and if necessary, each section is cleaned or replaced with a normal product.

また、電気集塵システムの運転継続に伴って、上段及び中段の電気集塵装置１０内に貯まったオイルはオイル流出孔２２ｂ及びオイル流入孔２４を介して下段の電気集塵装置１０の底面２１aに貯まり、下段の電気集塵装置１０で捕集されたオイルと合わさり、接続管４１、排出管４２を通ってオイル貯留部４３に徐々に溜まってゆく。従って、メンテナンスの際に定期的にオイル貯留部４３に溜まったオイルの廃棄も行う。 As the electrostatic precipitator 10 continues to operate, the oil accumulated in the upper and middle electrostatic precipitators 10 flows through the oil outflow hole 22b and the oil inflow hole 24 to the bottom surface 21a of the lower electrostatic precipitator 10. , is combined with the oil collected by the lower stage electrostatic precipitator 10 , passes through the connection pipe 41 and the discharge pipe 42 , and gradually accumulates in the oil reservoir 43 . Therefore, the oil accumulated in the oil reservoir 43 is also discarded periodically during maintenance.

本発明に係る電気集塵装置１０によれば、１種類のユニットの連結する個数を変更するだけで、様々なサイズや風量帯の空調機に対応する任意のサイズの電気集塵システムを構築することが可能である。また、塵埃捕集部３０の出し入れを上流側である筐体部２０の前面側から行うことが可能であり、複数のユニットを連結した後の電気集塵システムの大小に拘らず、メンテナンススペースを前面部のみに集約することができる。更に、制御部６０を設けることで、塵埃捕集部３０の不具合を個々にチェックでき、不具合の発生している塵埃捕集部３０のみに対して、メンテナンス作業を行うことが可能である。 According to the electrostatic precipitator 10 according to the present invention, an electrostatic precipitator system of any size corresponding to air conditioners of various sizes and air volume ranges can be constructed simply by changing the number of units to be connected of one type. Is possible. In addition, the dust collection unit 30 can be taken in and out from the front side of the housing unit 20, which is the upstream side. It can be concentrated only on the front part.
