Description

本発明は、主としてスプレー塗装作業を行う塗装ブース等の処理対象気体を吸引して清浄化を図る集塵装置に関するものである。   TECHNICAL FIELD The present invention relates to a dust collector for sucking and purifying a gas to be treated such as a painting booth that mainly performs spray painting work.

例えばスプレー塗装作業時においては、被塗装物に対して塗料を噴霧状で吹き付け、被塗装物の塗装を行う際に、被塗装物に塗着しない噴霧状態の塗料(塗料ミスト:塗料や有機溶剤の微粒子)は飛散状態となり、この塗料ミストが飛散状態のまま屋外に排出することを防止するために、塗装ミストの捕捉回収を行う必要がある。この塗料ミストの捕捉回収は、局所的吸引ではなくある程度広い範囲が対象となり、平行吸引を行うもので、その吸引排出流は0.4〜0.6m/秒程度の風速で行われている。   For example, at the time of spray coating work, the sprayed paint is sprayed on the object to be coated, and when the object to be coated is applied, the sprayed paint that does not adhere to the object to be coated (paint mist: paint or organic solvent) In order to prevent the paint mist from being discharged to the outside in the scattered state, it is necessary to capture and collect the paint mist. The paint mist is captured and collected over a wide range rather than local suction, and parallel suction is performed. The suction / discharge flow is performed at a wind speed of about 0.4 to 0.6 m / sec.

具体的には、特許文献1に開示されている水洗式塗装ブースと称されている集塵装置があり、当該装置は、塗装作業箇所の前面(スプレー噴射の対向面)に水流板を設け、前記水流板に水を流下させてウォーターカーテンを形成し、吸引排出流がこのウォーターカーテンに添って下降し、水と接触した塗装ミストが、水流と共に下方水槽に叩き落とされ、更に排気流路の途中に水シャワーを設けて、浮遊している塗装ミストを捉える構造を備えている。更に排気路にフィルターを配置し、当該フィルターで塗装ミストを捕捉する手段も知られている。   Specifically, there is a dust collector called a flush-type paint booth disclosed in Patent Document 1, the device is provided with a water flow plate on the front surface (opposite surface of spray spray) of the painting work location, Water is made to flow down on the water flow plate to form a water curtain, and the suction discharge flow descends along the water curtain, and the paint mist that has come into contact with the water is knocked down into the lower water tank together with the water flow, and further the exhaust flow path A water shower is provided on the way to capture floating paint mist. Furthermore, a means is also known in which a filter is disposed in the exhaust passage and the paint mist is captured by the filter.

また泡を使用した集塵装置も種々提案されている。例えば特許文献2には、泡生成液をして泡生成を行う泡発生板に粉塵流を衝突させて、粉塵を泡に付着させて泡溜りに落下させる泡を使用した集塵手段が示されているが、塗装ブースのように広い範囲から吸引排出による低速排出流では、吸引排出流による泡発生が困難であり、また別に泡生成を行って網状面(パンチグメタル面)に泡を供給する手段を採用しても、低速排出流の場合は、糖が泡面を通過することが困難であり、塗装ブース用の集塵装置としては適用できない。   Various dust collectors using bubbles have also been proposed. For example, Patent Document 2 discloses a dust collecting means that uses foam that causes a foam flow to collide with a foam generation plate that generates foam by using a foam generation liquid, attaches the dust to the foam, and drops it to the foam reservoir. However, it is difficult to generate bubbles due to the suction discharge flow with a low speed discharge flow by suction discharge from a wide range like a painting booth, and bubbles are generated separately to supply bubbles to the mesh surface (punched metal surface) Even in the case of adopting a means to do so, it is difficult for sugar to pass through the bubble surface in the case of a low-speed discharge flow, and it cannot be applied as a dust collector for a painting booth.

泡を使用した塗装ブースに対応できる集塵装置として、特許文献3に、塗装ミストの排気流路の途中にマイクロバブル発生器と攪拌機構を設けて、マイクロバブルに塗装ミストを付着させて捕捉する手段が開示されている。   As a dust collector capable of handling a paint booth that uses foam, Patent Document 3 provides a microbubble generator and a stirring mechanism in the middle of the exhaust flow path of the paint mist, and attaches the paint mist to the microbubble and captures it. Means are disclosed.

広い範囲からの吸引排気流に対応できる集塵として、前記特許文献1に開示されているような、排気流に乗って移動する飛散状態の塗装ミストをウォーターカーテンで捕捉する手段では、塗装ミストとウォーターカーテンとの接触確率が必ずしも高くなく、吸引排出流が水と非接触の状態のままウォーターカーテンの表面を流れてしまうことが多く、塗装ミストの捕捉効率が悪い。   As a dust collection that can handle a suction exhaust flow from a wide range, as disclosed in Patent Document 1, a means for capturing a scattered paint mist moving on an exhaust flow with a water curtain, The probability of contact with the water curtain is not necessarily high, and the suction discharge flow often flows on the surface of the water curtain in a non-contact state with water, so that the efficiency of capturing the paint mist is poor.

また排気路においての塗装ミスト捕捉においては、水シャワーを使用する場合には水と接触しない塗装ミストを捕捉できないという問題があり、またフィルターを採用する場合には、捕捉効率を高めるために細かいフィルターを採用すると、当然に強い排気能力を備えた排気ファンを採用する必要があり、効率的であるとは言えない。   In addition, when using a water shower, there is a problem that the paint mist that does not come into contact with water cannot be captured when using a water shower. When a filter is used, a fine filter is used to increase the capture efficiency. Of course, it is necessary to use an exhaust fan with a strong exhaust capacity, which is not efficient.

また排気流路に、前記の水シャワーに替えてマイクロバブルを採用して塗装ミストの捕捉する手段は、上部の排気ファンによって塗装ミストを含む排気流を下方から吸い上げ、噴霧されるマイクロバブル(泡状水微粒子群)の落下で上昇する塗装ミスト混在排気流を抑え込んで、塗装ミストをマイクロバブルに付着させるものである。   In addition, the means for capturing the paint mist by adopting micro bubbles instead of the water shower in the exhaust flow path is a micro bubble (foam) that sucks the exhaust flow containing the paint mist from below by the upper exhaust fan and sprays it. The coating mist adhering to the microbubbles is suppressed by suppressing the exhaust flow of the coating mist rising due to the fall of the fine water particles).

このため排気能力を高めてしまうと、塗装ミストがマイクロバブルに付着した状態で、排気流と共に流されてしまうので、マイクロバブルが所定の空間内である程度の衝突合体を繰り返し、相応の大きさの水粒子となって落下させるために排気能力を低くすると、逆に塗装作業空間(塗装ミスト発生源)における塗装ミスト吸引がスムーズに行われないので、排気流の排出能力と、マイクロバブルの発生量の制御が煩雑であるという問題が生ずる。   For this reason, if the exhaust capacity is increased, the paint mist adheres to the microbubbles and flows along with the exhaust flow. Therefore, the microbubbles repeatedly collide and collide to some extent in a predetermined space, and have a corresponding size. If the exhaust capacity is lowered in order to drop it as water particles, the paint mist suction in the painting work space (paint mist generation source) is not performed smoothly, so the exhaust flow discharge capacity and the amount of microbubbles generated There arises a problem that the control of is complicated.

そこで本発明は、広い範囲からの吸引排出を行うと共に、前記排出流と接触面積が大きい泡による塗装ミスト等の捕捉を行うことで、塗装作業空間における塗装ミスト等を確実に捕捉できる集塵装置を提案したものである。   Accordingly, the present invention provides a dust collector capable of reliably capturing paint mist and the like in a painting work space by performing suction and discharge from a wide range and capturing the paint mist and the like by bubbles having a large contact area with the discharge flow. Is proposed.

本発明(請求項1)に係る集塵装置は、泡液(泡の他に非泡の水分の含有量が多く、流動性を有する泡を意味する)を受け入れる下方水槽と、ミスト含有の吸引排出流を泡と接触させてミスト除去を行うミスト除去機構部と、ミスト除去機構部の背面空間からミスト除去の気体を排出して吸引排出流を作りだす排気機構部からなる集塵装置であって、ミスト除去機構部が、流動性を有する泡液を生成して供給する泡発生部と、平面扁平コの字状板体を、表裏交互に適宜間隔を開けて噛み合うように配置して、吸引排出流が衝突する衝突面、及び衝突後に前記噛み合い箇所から背後へ通過する通気路を設けると共に、前記泡発生部から供給される泡液が流下する衝突板部と、衝突板部の背面に多数の小孔を穿設した泡阻止板と、泡阻止板の表面へシャワー水を浴びせるシャワー部を備えてなることを特徴とするものである。 The dust collector according to the present invention (Claim 1) includes a lower water tank for receiving a foam liquid (meaning a foam having a high content of non-foamed moisture in addition to foam and having fluidity), and a suction containing mist. A dust collector comprising a mist removal mechanism that removes mist by bringing the exhaust flow into contact with bubbles, and an exhaust mechanism that discharges mist removal gas from the back space of the mist removal mechanism to create a suction discharge flow. The mist removing mechanism part generates and supplies a foam liquid having fluidity, and the flat flat U-shaped plate body is arranged so that the front and back are alternately meshed with each other at appropriate intervals. A collision surface on which the discharge flow collides , and a ventilation path that passes from the meshing location to the back after the collision are provided, and a large number of collision plate portions on which the foam liquid supplied from the bubble generation portion flows down are provided on the back surface of the collision plate portion. Foam prevention plate with a small hole and the surface of the foam prevention plate It is to characterized in that it comprises a shower unit hurl shower water.

而して排気機構部を動作させると、ミスト除去機構部の背面空間が負圧になり、ミスト除去機構部前面側の広い範囲から処理対象気体(ミスト含有気体)を吸引することになる。この時に泡発生部で泡液を生成して衝突板部に供給すると、泡液は衝突板部表面をゆっくり(目安として10cm/秒)と流下し、処理対象気体は、遅速の吸引排出流となり、処理気流は衝突板部の前面板と後面板に衝突して横流し、前後板の縁板間を通過して衝突板部の背後に流れる。従って吸引排出流は、流下する泡液との接触が確実になされ、泡の表面にミストが付着し、ミストは泡液と共に下方水槽に流下することになる。 Thus, when the exhaust mechanism is operated, the back space of the mist removing mechanism becomes negative pressure, and the processing target gas (mist-containing gas) is sucked from a wide range on the front side of the mist removing mechanism. At this time, when foam liquid is generated in the foam generating part and supplied to the collision plate part, the foam liquid slowly flows down the surface of the collision plate part (as a guideline, 10 cm / second), and the gas to be processed becomes a slow suction discharge flow. The processing airflow collides with the front plate and the rear plate of the collision plate portion and crossflows, passes between the edge plates of the front and rear plates, and flows behind the collision plate portion. Therefore, the suction discharge flow is surely brought into contact with the falling foam liquid, and mist adheres to the foam surface, and the mist flows down to the lower water tank together with the foam liquid.

特に泡液は、液量が少なく泡が多い場合には、流動性が少なく泡全体で衝突板部の前面全体を覆ってしまい、衝突板部の通路も塞がれ、吸引排出流がミスト除去機構部を抜けることができず、ミスト除去効率が低下する。また逆に液量が多く泡量が少ないと、流動性が大きく通路の閉塞が生じないが、泡へのミスト付着が少なくなりやはりミスト除去効率が悪くなる。泡量と流動性を加味すると、前記したとおり流下速度が10cm/秒程度となるように相応の比重となる泡液を生成するものである。   In particular, when the amount of foam liquid is small and the amount of foam is large, the fluidity is low and the entire foam covers the entire front surface of the collision plate, and the passage of the collision plate is also blocked, and the suction discharge flow is removed by mist. The mechanism cannot be removed, and the mist removal efficiency is reduced. Conversely, if the amount of liquid is large and the amount of foam is small, the fluidity is large and the passage is not blocked, but mist adherence to the foam is reduced and mist removal efficiency is deteriorated. When the amount of foam and fluidity are taken into account, as described above, a foam liquid having an appropriate specific gravity is generated so that the flow-down speed is about 10 cm / second.

衝突板部で泡にミストを付着させ、下方水槽に流下してミスト除去を行うが、ミストの付着が充分になされるように泡量を増加すると、当然に泡の一部は空中浮遊することになり、ミストを付着した泡の一部は、吸引排出流に乗って衝突板部の通路を通過して衝突板部の背後に流れ込む。吸引排出流のうち泡以外の気体は、小孔を通じて背後空間に達し、ミストを付着した泡は、小孔を通過することができず、泡阻止板にぶつかり当該泡阻止板に付着し、更にシャワー水で下方水槽に流れ落ちることになる。   Mist is attached to the foam at the collision plate, and it flows down to the lower water tank to remove the mist, but if the amount of foam is increased so that the mist adheres sufficiently, naturally part of the foam will float in the air Then, a part of the foam with the mist adheres to the suction discharge flow, passes through the passage of the collision plate portion, and flows behind the collision plate portion. Gases other than bubbles in the suction discharge flow reach the back space through the small holes, and the bubbles attached with mist cannot pass through the small holes, collide with the bubble blocking plates, adhere to the bubble blocking plates, and It will flow down to the lower tank with shower water.

従って塗装作業における被塗装物に塗着しない噴霧状態の塗料(塗料ミスト)等を含んだ処理対象気体は、吸引排出流となって衝突板部で泡と接触して、気体中のミストが泡に付着し、前記のミストを付着した泡は衝突板の表面を流れ落ち、空中に飛散したミストを付着した泡は、泡阻止板に付着してシャワー水で流下し、ミスト除去機構部の背後にはミストが除去された吸引排出流となって流れ込み、外気に放出されるものである。   Therefore, the gas to be treated, including sprayed paint (paint mist) that does not adhere to the object to be coated in the painting operation, becomes a suction discharge flow and comes into contact with the foam at the collision plate portion, and the mist in the gas is foamed. The bubbles attached to the mist flow down the surface of the collision plate, and the bubbles attached to the mist scattered in the air adhere to the bubble prevention plate and flow down with shower water, behind the mist removing mechanism. Is a suction exhaust flow from which mist is removed and flows into the outside air.

また本発明(請求項2)に係る集塵装置は、特に、衝突板部における衝突面に、泡液流下ガイド凹凸面を形成してなるもので、泡液流は、収束する性質が認められるが、前記のガイドによって泡液流が偏ることなく衝突面全体を流下し、ミストの付着効率の低下を防ぐ。   In addition, the dust collector according to the present invention (Claim 2) is formed by forming a foam liquid flow lower guide uneven surface on the collision surface of the collision plate portion, and the foam liquid flow has a converging property. However, the above-described guide causes the foam liquid flow to flow down the entire collision surface without being biased, and prevents the mist adhesion efficiency from being lowered.

本発明は上記のとおりで、塗装ミスト等を含む処理対象気体を、泡と接触させてミストを泡に付着させてミスト除去を行う集塵手段において、流下泡液との衝突接触並びに、浮遊泡の水シャワーによる流下の組み合わせを採用することによって、広範囲から吸引する排出流から、揮発性有機溶剤を含む塗料ミストの殆どを除去できる集塵装置を実現したものである。   The present invention is as described above. In the dust collecting means for removing the mist by bringing the gas to be treated including the coating mist and the like into contact with the foam and attaching the mist to the foam, the collision contact with the falling foam liquid and the floating foam By adopting a combination of flow down by water shower, a dust collector capable of removing most of the paint mist containing the volatile organic solvent from the exhaust flow sucked from a wide range is realized.

次に本発明の実施の形態について説明する。図示した集塵装置は、塗装対象物Aに対して塗料噴霧器Bで塗装を行う塗装ブースに設置されるもので、前方開口の本体ボックス1或いは所定の前方開口の密閉空間を構成し、下方水槽1、ミスト除去機構部2、排気機構部3を組み込んでいるものである。   Next, an embodiment of the present invention will be described. The illustrated dust collecting apparatus is installed in a painting booth that paints a painting object A with a paint sprayer B, and constitutes a main body box 1 with a front opening or a sealed space with a predetermined front opening, and a lower water tank. 1. A mist removing mechanism 2 and an exhaust mechanism 3 are incorporated.

下方水槽1は、ミスト除去機構部2及び排気機構部3の下方全体を占める大きさで、塗装ミストを受け入れるもので、必要に応じて沈殿する塗料スラッジの強制排出機構を付設するものである。   The lower water tank 1 occupies the entire area below the mist removing mechanism section 2 and the exhaust mechanism section 3 and receives the coating mist, and is provided with a forcibly discharging paint sludge for sedimentation as required.

ミスト除去機構部2は、泡発生部21、衝突板部22、泡阻止板23、及びシャワー部24で構成される。泡発生部21は、界面活性剤を混入した泡生成液と泡の生成に必要な空気供給部と攪拌部を備えたもので、所定の流動性を備えた泡液(28g/L程度)Dを生成し、放出筒211から、下方の衝突板部22の衝突板の衝突面221に流下させるものである。   The mist removing mechanism unit 2 includes a bubble generation unit 21, a collision plate unit 22, a bubble prevention plate 23, and a shower unit 24. The foam generating unit 21 includes a foam generating liquid mixed with a surfactant, an air supply unit necessary for generating foam, and a stirring unit. The foam generating liquid 21 has a predetermined fluidity (about 28 g / L) D. And flow down from the discharge cylinder 211 to the collision surface 221 of the collision plate of the lower collision plate portion 22.

衝突板部22は、衝突面221の左右縁を前後方向に折曲した平面扁平コの字状板体を、前記折曲縁222が適宜間隔を開けて噛み合うように多数横列配置すると共に、噛み合い箇所を背面への通過路223に形成して、塗装ブースに対応する広い範囲からの平行吸引が行われるようにしたもので、下方水槽1の集塵水Cの水面直上或いは水面下まで設けている。更に前記衝突面221には、泡液流下ガイド凹凸面を形成してなるものである。   The collision plate portion 22 has a plurality of flat, flat, U-shaped plates that are bent in the front-rear direction on the left and right edges of the collision surface 221 so that the bent edges 222 mesh with each other at appropriate intervals. The part is formed in the passage 223 to the back so that the parallel suction from a wide range corresponding to the painting booth is performed, and provided up to the water surface of the collected water C in the lower water tank 1 or below the water surface. Yes. Further, the impingement surface 221 is formed with a bubble liquid flow guide uneven surface.

泡阻止板23は、衝突板部22の背後に設けたもので、多数の小孔231を穿設してなるもので、前記小孔231は、泡発生部21で生成した泡の大きさよりも充分に小径としたものである。   The bubble prevention plate 23 is provided behind the collision plate portion 22 and is formed with a large number of small holes 231. The small holes 231 are larger than the size of the bubbles generated by the bubble generation portion 21. The diameter is sufficiently small.

シャワー部24は、泡阻止板23の上方に配置し、泡阻止板23の前面にシャワー水Eを降り注ぐようにしたものである。   The shower unit 24 is arranged above the foam prevention plate 23 so as to pour shower water E onto the front surface of the foam prevention plate 23.

排気機構部3は、泡阻止板23の背後空間31の気体を外気に排出する排気路32及び排気ファン33を備えたもので、排気ファン33は、本集塵機を塗料ブースに採用した場合には、塗料ミストの捕捉に適する平行集塵流となる吸引排出流(0.4〜0.6m/s)Fが生ずるような出力で動作させるものである。   The exhaust mechanism unit 3 includes an exhaust path 32 and an exhaust fan 33 for exhausting the gas in the space 31 behind the foam prevention plate 23 to the outside air. The exhaust fan 33 is used when the dust collector is used in a paint booth. The suction discharge flow (0.4 to 0.6 m / s) F, which is a parallel dust collection flow suitable for capturing the paint mist, is operated at an output.

而して前記集塵装置を塗装ブースに設置して使用するもので、装置は、泡発生部21で、所定の流動性を備えた泡(泡液D)を生成して、衝突板部22の前面の衝突面221に供給してゆっくりと流下させ、シャワー部24から泡阻止板23に向けてシャワー水Eを降り注ぎ、排気ファン33を駆動することで、その機能を発揮するものである。   Thus, the dust collecting device is used in a painting booth. The device generates a bubble (foam liquid D) having a predetermined fluidity at the bubble generating unit 21, and the collision plate unit 22. It is supplied to the front collision surface 221 and slowly flows down, shower water E is poured from the shower portion 24 toward the bubble prevention plate 23, and the exhaust fan 33 is driven to exert its function.

排気ファン33の駆動によってミスト除去機構部2の背面空間31が負圧となり、ミスト除去機構部2の前面側から当該空間の気体を吸引することになる。即ち塗装対象物Aに対して塗料噴霧器Bで塗装作業を行うと、当該作業空間に漂う塗装ミストは、吸引排出流Fと共にミスト除去機構部2側に流れる。   By driving the exhaust fan 33, the back space 31 of the mist removing mechanism 2 becomes negative pressure, and the gas in the space is sucked from the front side of the mist removing mechanism 2. That is, when a painting operation is performed on the coating object A with the paint sprayer B, the coating mist drifting in the working space flows to the mist removing mechanism 2 side together with the suction discharge flow F.

前記吸引排出流Fは、衝突板部22の衝突面221に衝突し、衝突後に気流の方向を変えて通過路223を通過して、衝突板部22の背後に流れ込む。この吸引排出流Fが衝突面221に衝突すると、当該衝突面221をゆっくりと流下する泡液Dと接触し、泡の表面に塗装ミスト(塗料や溶剤の微粒子)が付着する。従って塗装ミストは泡液Dと共に下方水槽1に流下し、塗装ミストを含む集塵水Cは、適宜処理されることになる。   The suction exhaust flow F collides with the collision surface 221 of the collision plate portion 22, changes the direction of the airflow after the collision, passes through the passage 223, and flows behind the collision plate portion 22. When this suction / discharge flow F collides with the collision surface 221, it comes into contact with the foam liquid D that slowly flows down the collision surface 221, and coating mist (fine particles of paint or solvent) adheres to the surface of the foam. Therefore, the coating mist flows down to the lower water tank 1 together with the foam liquid D, and the dust collection water C containing the coating mist is appropriately processed.

また泡液Dは相応の流動性を備えているので衝突面221に添ってゆっくりと流下するが、塗装ミストの付着効率を高めるために、当然に泡量をできるだけ多くするので、泡液Dから離脱して浮遊する泡D1も生ずる。この浮遊した泡D1にも塗料ミストが付着し、吸引排出流Fに乗って通過路223を通って衝突板部22の背後に流れ込む。   Further, since the foam liquid D has appropriate fluidity, it slowly flows down along the collision surface 221. Naturally, in order to increase the adhesion efficiency of the coating mist, the amount of foam is naturally increased as much as possible. The bubble D1 which detaches and floats is also generated. The paint mist also adheres to the suspended bubble D1 and rides on the suction discharge flow F and flows into the back of the collision plate portion 22 through the passage 223.

衝突板部22に流れ込んだ吸引排出流Fは、小孔231を通過して背後空間31に入り、排気ファン33によって排気路32から外気に放出されるものであるが、前記の衝突板部22の背後に流れ込んだ塗装ミストが付着した泡D1は、小孔231によって背後空間31に流れ込むことが阻止され、小孔231を塞いだり、泡阻止板23に付着することになる。そこにシャワー部24からシャワー水Eが浴びせられるので、泡D1は破裂し、泡D1に付着した塗装ミストは、シャワー水Eと共に下方水槽1に流れ込むものである。   The suction / discharge flow F that has flowed into the collision plate portion 22 passes through the small hole 231 and enters the back space 31 and is discharged from the exhaust passage 32 to the outside air by the exhaust fan 33. The bubbles D1 to which the coating mist that has flown behind the mist adheres are prevented from flowing into the back space 31 by the small holes 231 and close the small holes 231 or adhere to the bubble prevention plate 23. Since the shower water E is showered there, the foam D1 is ruptured, and the coating mist adhering to the foam D1 flows into the lower water tank 1 together with the shower water E.

従って塗装ミストは、泡(流下している泡及び浮遊する泡)に接触して付着し、泡液Dやシャワー水Eと共に下方水槽1に流れ込むようにして、吸引排出流Fからの塗装ミスト除去を確実に行う様にしたもので、特に本発明は、泡によって遅速の吸引排出流の流路が塞がれることが無く、且つ塗装ミストを含む吸引排出流と泡との接触を確実になされるように、流動性を有する泡液を採用すると共に、浮遊するミスト付着の泡の捕捉をも確実に行い、泡による塗装ミスト(塗料や揮発性有機溶剤を含む種々溶剤の微粒子等)の捕捉除去を実現したものである。   Therefore, the paint mist contacts and adheres to the foam (flowing foam and floating foam) and flows into the lower water tank 1 together with the foam liquid D and the shower water E to remove the paint mist from the suction discharge flow F. In particular, according to the present invention, the flow path of the slow suction discharge flow is not blocked by the foam, and the suction discharge flow including the paint mist and the foam are reliably in contact with each other. In addition to adopting fluid foam liquid, it also reliably captures floating mist adhering bubbles, and captures paint mist (fine particles of various solvents including paints and volatile organic solvents) by foam. Removal is realized.

尚本発明は、塗装ブースに採用する以外にも、他の集塵装置としても適用できるものである。   In addition, this invention is applicable also as another dust collector other than employ | adopting as a painting booth.
