【0018】
【発明の実施の形態】
以下,図面を参照して,この発明による散水式集塵装置の一実施例を説明する。図1はこの発明による散水式集塵装置の一実施例を示す概略説明図,図2は図1の散水式集塵装置の要部を説明する分解図,図3は図1の散水式集塵装置の原理を示す説明図,及び図4は図1の散水式集塵装置におけるロートの終端領域を示す斜視図である。
【0019】
この散水式集塵装置は,主として,塗料等の粉塵が発生する粉塵発生領域14の上方領域に粉塵含有空気を吸引する広角に開口する吸引口9を上部に且つ排気口10を下部に有するロート1,吸引口9に隣接して吸引口全域にわたってロート1内に水を散水する散水ノズル8,ロート1の底面に形成された粉塵含有水を排水する排水口26に連結された第1樋5を通じて粉塵含有水を回収するタンク4,ロート1の下部の上面28に開口した排気口10に連通する空気室29を形成するドラム2,及びドラム2に隣接して設けられ且つ粉塵発生領域14からロート1とドラム2を通って浄化された空気を外部に排気する吸引ファン12を有する。
【0020】
この散水式集塵装置において,ロート1は,ドラム2の上面開口部32を覆うように載置され,その際に,ロート1の底部17の湾曲面31がドラム2の当接フランジ33に当接して位置決めして安定して設定されている。散水ノズル8は,ロート1の天板部上に支持された散水管35に多数個のジョイント管を配備し,ジョイント管をロート1の内側へ押入れて構成されている。ロート1は,特に,吸引口9が形成されたロート1の上部から下部に向かって狭窄した湾曲通路30に形成されている。粉塵含有空気は,湾曲通路30を通過する際に,粉塵が散水された水へ混入されて移行する。ロート1の湾曲通路30を通過した粉塵含有空気と粉塵含有水は,ロート1の下部終端部材15の湾曲面31に沿ってロート1内で反転攪乱され,粉塵含有水と空気とに分離され,空気は上昇して上面の排気口10からドラム2内へ流入し,粉塵含有水は下降して排水口26から排水される。
【0021】
この散水式集塵装置において,粉塵発生領域14は,例えば,スプレーガン21等によって被塗装体である物体22の表面に対して塗装を施す塗装領域である。粉塵発生領域14には,その周囲にエアカーテン25を形成するエア噴口7が設けられている。粉塵発生領域14にエアカーテン25を形成することによって,発生した粉塵を粉塵発生領域14外に散乱させることなく,作業環境を汚染することを防止する。
【0022】
ドラム2の底部18に溜まった粉塵含有水は,ドラム2の底面に形成された第2排水口27から第2樋6を通じてタンク4に排水される。第1樋5及び第2樋6と,タンク4との間には,フィルタケース34に脱着可能に収容されるフィルタ3が設けられている。粉塵含有水は,フィルタ3によって浄化され,タンク4へと落下する。タンク4は,その内部の間には溢流堰13が設けられ,フィルタ3から送り込まれた水を溜める溜部19と,溢流堰13を越えた溢流水を溜める浄水部20とに区画されている。浄水部20の浄化された水は,再び散水ノズル8から散水するのに利用される。
【0023】
また,吸引ファン12は,浄化された空気をドラム2の排気口16から吸引して上方に向かって開口する排気口36からダクト24を通じて排気する。粉塵発生領域14を構成する領域には,ロート1の吸引口9に向かって延びる庇等のガイド部材11が設けられている。また,フィルタ3で浄化されてタンク4に回収された水は,循環して散水ノズル8からロート1内へ散水される。
【0024】
この散水式集塵装置は,上記のように構成されているので,粉塵発生領域14の粉塵含有空気は,吸引ファン12が作動することによって,エア噴口7からの補助気流に乗って上昇気流となり,庇等のガイド部材11に沿ってロート1の吸引口9からロート1内に吸い込まれ,塗装等で使用される有機粉末,有機溶剤等の粉塵が人体等に付着するのが軽減され,作業環境が良好になる。ロート1には,散水ノズル8から水が散水されるので,散水された水と粉塵含有空気とは,ロート1内の狭窄した湾曲通路30を通って遠心力によって,粉塵と水とがロート1の壁面に沿って膜状になって流下すると共に空気が加圧状態になって下方へ送られ,ロート1の底部17に達する。ロート1の底部17では,粉塵含有水と空気とがロート1の底部湾曲面31で反転攪乱され,空気と粉塵含有水とに分離され,空気は排気口10からドラム2内の空気室29に流入し,粉塵含有水は底面の排水口26から第1樋5を通ってフィルタ3へ流下する。
【0025】
また,ドラム2の空気室29に流入した空気には,多少の水が含まれているので,その水はドラム2の底部18に設けた排水口27から第2樋6を通ってフィルタ3へ流下する。ドラム2の空気室29における浄化された空気は,吸引ファン12によって排気口16を通じて吸引され,ダクト24から外部へ排気される。一方,フィルタ3へ送り込まれた粉塵含有水は,フィルタ3によって粉塵が捕集され,浄化された水がタンク4へ流下する。フィルタケース34に収容された袋状のフィルタ3は,粉塵の捕集量が所定量以上になれば,新しいフィルタ3に交換すればよい。また,タンク4内の浄化された水は,循環させて再度散水に利用することができる。
【0026】
【発明の効果】
この発明による散水式集塵装置は,上記のように構成されているので,粉塵の吸引分離と,粉塵の集塵廃棄を同時に行うことができ,従来のように,粉塵空気が下方へ移動して人体等に付着することが防止され,また,粉塵発生領域において飛散浮遊している粉塵を上昇気流に乗せてロートへ吸引し,直ちに下降する際に,粉塵含有空気に対して散水を浴びさせて粉塵含有空気から粉塵を水へと混入させて移行させると共に,ロート内での気流をロート終端で反転攪乱させて浄化させた空気をロートの下部の上面に形成された排気口からドラムへと吸引し,一方,粉塵は,水と一緒にロートの底部の排水口から落下させ,粉塵をフィルタで集塵回収し,浄化された水はタンクへ回収して再度散水ノズルへと循環させる。また,フィルタで集塵回収した粉塵はフィルタを所定の場所に廃棄処理すれば,粉塵で周囲環境を汚染させることがない。
【0027】
また,この散水式集塵装置は,ロートの湾曲通路によって粉塵含有空気を反転旋回させて攪拌し,空気中の粉塵を水中へ有効に混入させることができ,従来のような遮蔽板や邪魔板等を設ける必要がなく,空気抵抗が少なくなり,吸引ファンも小型で十分であり,省エネルギの装置を提供できる。また,散水に利用する水は,ロート内の攪拌や配管を流れる循環容量であればよく,少量でよく,汚水処理量は格段に少なくなる。

Since the sprinkling dust collector according to the present invention is configured as described above, it can simultaneously perform dust suction separation and dust collection and disposal, and dust air can move downward as in the past. In addition, the dust that is scattered and suspended in the dust generation area is sucked into the funnel and then sucked into the funnel, and when it descends immediately, the dust-containing air is sprayed with water. Dust is mixed with water from the dust-containing air and transferred, and the air purified in the funnel by reversing the airflow at the end of the funnel is transferred from the exhaust port formed on the upper surface of the funnel to the drum. While sucking, the dust is dropped together with water from the drain at the bottom of the funnel, and the dust is collected and collected by a filter. The purified water is collected in a tank and circulated again to the watering nozzle. The dust collected and collected by the filter is not contaminated by the dust if the filter is disposed in a predetermined place.
[0027]
In addition, this sprinkling dust collector can swirl the dust-containing air by the curved passage of the funnel, and can effectively mix the dust in the air into the water. Etc., air resistance is reduced, the suction fan is small and sufficient, and an energy-saving device can be provided. The water used for sprinkling may be a stirring capacity in the funnel or a circulation capacity that flows through the pipe, and may be a small amount, and the amount of sewage treatment will be greatly reduced.
