Description

【０００１】
【産業上の利用分野】
本発明は混合流体分離装置に係わり、特に各種工場における廃油を含んだ排水、切削油と防錆油の混合油等、比重の異なる流体混合物の分離に適した混合流体分離装置に関する。
【０００２】
【従来の技術】
従来、機械工場、ガソリンスタンド、金属表面処理工場、食品加工工場等における廃油を含んだ排水、切削油と防錆油の混合油等から、各成分を分離、回収、除去するため、下記のような装置があった。
【０００３】
（１）機械的混合流体分離装置、電気的混合流体分離装置、または溶剤、凝集剤、吸着剤やフィルターを使用した混合流体分離装置。
【０００４】
しかしながら、（１）の分離装置は、装置そのものが高価であり運転経費もかかるうえ、目詰り、故障の発生、排水中の油分濃度（以下原水負荷という）の巾が狭い等の難点があった。その解決策として、
（２）比重の異なる混合流体を分離するため、混合流体の比重差および水位差を利用し、運転経費もかからず、経済的な油水分離方法（特開昭５２−１１１０６０号公報）および（３）油水比重差分離装置（特開昭５３−９７６７０号公報）が提案されていた。
【０００５】
【発明が解決しようとする課題】
混合流体の比重差および水位差を利用する（２）の油水分離方法（特開昭５２−１１１０６０号公報）は、動力を使用せず、油と水の比重差および水位差により、油水分離、油分回収を行い、故障の発生はなく、原水負荷の変動にも対応し、運転経費は安価になったが、油と水の分離を促すための複数枚の斜板（ギャラリー）が原水の流れにそのまま対応しているため、原水の流れはスムーズとなり、結果的には油水分離が不完全で、かつ、装置が大き過ぎるという難点があった。
【０００６】
また、（３）の波状に屈曲した分離板を設けた油水比重差分離装置（特開昭５３−９７６７０号公報）は、ギャラリー内の構造を複雑にして、装置を小型にすると共に、油水分離を促進させようとしてはいるが、ギャラリー内の屈曲した分離板が複雑、過多のため、ギャラリーは一部分のみ機能するという欠点が生じていた。
【０００７】
更に、油回収部についてみると、（２）、（３）ともに、浮上した大きな油滴およびギャラリーで分離された油滴は浮上して油溜室に回収されるが、ギャラリーを通過した水分中の油は未回収のまま排水口から排出されてしまうという難点もあった。
【０００８】
本願出願人は、混合流体の比重差および水位差により混合流体を各構成流体に分離させる水槽として、図５、図６に示すように、混合流体の流入口１１と、分離された比重の軽い流体を貯留する複数個の貯留部Ｇ、Ｈ、Ｊ、Ｋ、２８４と、分離された比重の重い流体を流入口１１との水位差により排出する排出口１２とを備え、排出口１２に向う混合流体をさえぎり水槽１’内で溢流させる複数個の仕切部２、３、４と、分離された比重の軽い流体を貯留部に導く複数個の分取口５、６、７、８、２８５と、混合流体から比重の軽い流体を分離浮上させるため排出口側が高く流入口側を低く傾斜させた複数個の傾斜部材９０で構成する傾斜流路部９とを設けた混合流体分離装置を提案している（特願平５−１５７４８２号）。
【０００９】
そして複数個の貯留部の１つＧは、傾斜流路部９に対して流入口１１側に設け、複数個の貯留部の他の１つＨは傾斜流路部９に対して排出口１２側にそれぞれ設けたものである。
【００１０】
傾斜流路部９に対して流入口１１側に設けられた貯留部Ｇにおいて分離された比重の重い流体を排出口１２側に導く誘導管２８１を設け、この誘導管２８１によって排出口１２側に導びかれた比重の重い流体の動きを制限する流路制限部２８７、２８８を備え、排出口１２側に導びかれた比重の重い流体中に残存する比重の軽い流体を分離させる残存分離部２８２を設けたものである。
【００１１】
更に、複数個の仕切部２、３、４により水槽１’の混合流体の面を仕切る各室２１、２２、２３、２４、２５、２６、２７および貯留部Ｈ、Ｇ、Ｊ、Ｋ、２８４のうち少なくとも流入口に連結された室２１の角面を曲面構造Ｒとするものである。
【００１２】
この装置を設置配管後は動力源、フィルター、吸着剤等一切使用せず、効率良く油分を分離回収できると共に、非常に経済的で、設置スペースも小さく押えられるようになった。
【００１３】
しかしながら、分離された比重の軽い流体を貯留部Ｇに導く分取口５、貯留部Ｈに導く複数個の分取口６、７や、貯留部Ｇから貯留部Ｋへの分取口８、残存分離部２８２から貯留部２８４への分取口２８５の高さを処理流量にあわせてボルト締めするという微調整を行うが、分取口の数が7箇所と多いので調整に手間取るという難点があり、更に、全ての分取口がボルト締めによる固定式のため液量の変動により比重の重い流体が流入してしまうという難点があった。分取口の形状が概略円形のため、粘度の高い流体やゴミ等を回収する位置に高さ調整すると、排出口１２に向かうべき流体の捕集量が多くなるという難点もある。
【００１４】
また、傾斜流路部９を２個９ａ、９ｂ必要とし、組立時に部品が多くなると共に時間もかかり、装置の小型化にも限度があった。
【００１５】
更に、流入口１１側に比重の軽い流体を貯留し回収口Ｋ1に接続される貯留部Ｋが設けられ、排出口１２側にも比重の軽い流体を貯留し回収口２８６に接続される貯留部２８４が設けられるため、本体の小型化を阻む要因であった。また、これら２つの貯留部Ｋ、２８４から回収された回収流体に比重の重い流体も含まれるので、２箇所からロスが発生し効率が低下するという難点があった。
【００１６】
流入口１１側の貯留部Ｇから排出口１２に送られる誘導管２８１中の排水には、分離しきれない比重の軽い流体が約１０パーセント含まれ、分離効率を低下させていた。
【００１７】
本発明は、上記種々の難点を解決し、効率よく経済的に油水分離等が行なうことができるコンパクトな混合流体分離装置を提供することを目的とする。
【００１８】
【課題を解決するための手段】
上記の目的を達成するために、本発明による混合流体分離装置は、混合流体の比重差および水位差により混合流体を各構成流体に分離させる水槽を使用する混合流体分離装置であって、混合流体の流入口と、分離された比重の重い流体を流入口との水位差により排出する排出口と、分離された比重の軽い流体を貯留するため流入口側に設けられた主貯留部および排出口側に設けられた副貯留部とを備え、流入口から排出口に向かう混合流体をさえぎる複数個の仕切り部と、混合流体から比重の軽い流体を分離浮上させるため排出口側が高く流入口側を低く傾斜させた複数個の傾斜部材で構成する傾斜流路部と、主貯留部および副貯留部に比重の軽い流体を導く複数個の分取口と、主貯留部から比重の軽い流体を回収するための回収口とを設け、傾斜流路部を構成する傾斜部材の下面には、比重の軽い流体の浮上を流入口側から排出口側に誘導する溝と、溝への比重の軽い流体の集合を誘導する複数の帯状板とが設けられ、帯状板は溝に対して切妻屋根型または人字型に鋭角をもって設けられるものである。
【００１９】
本発明による混合流体分離装置は、回収口に比重の軽い流体の回収液面高を調整する調整板を取付け、調整板に回収口に相当する調整口を穿設し、調整板にエア駆動式エアシリンダーを連結して主貯留部に比重の軽い流体が溜まったときにエア駆動式エアシリンダーを駆動して調整板を下げ比重の軽い流体を調整口および回収口から回収するものである。
【００２０】

【００２１】
本発明による混合流体分離装置は、副貯留部に流入した比重の軽い流体を誘導管を介して主貯留部に還流させるものである。
【００２２】
また、本発明による混合流体分離装置は、混合流体の比重差および水位差により混合流体を各構成流体に分離させる水槽を使用する混合流体分離装置であって、混合流体の流入口と、分離された比重の重い流体を流入口との水位差により排出する排出口と、分離された比重の軽い流体を貯留するため流入口側に設けられた主貯留部および排出口側に設けられた副貯留部とを備え、流入口から排出口に向かう混合流体をさえぎる複数個の仕切り部と、混合流体から比重の軽い流体を分離浮上させるため排出口側が高く流入口側を低く傾斜させた複数個の傾斜部材で構成する傾斜流路部と、主貯留部および副貯留部に比重の軽い流体を導く複数個の分取口と、主貯留部から比重の軽い流体を回収するための回収口とを設け、主貯留部において分離された比重の重い流体を外設された逆流防止トラップを介して流入口に導くものである。
【００２３】
本発明による混合流体分離装置は、水槽の混合流体の面が仕切られた各室、貯留部および副貯留部のうち少なくとも流入口に連結された室の角面を曲面構造とするものである。
【００２４】
このように構成された本発明による混合流体分離装置は、装置を設置配管後は動力源、フィルター、吸着剤等一切使用せず、効率良く油分を分離回収できると共に、排水には油分を流出せず、非常に経済的で、設置スペースも最小限に押えられる。
【００２５】
【実施例】
以下に本発明による混合流体分離装置について図面を参照して詳述する。
【００２６】
図１（ａ）、（ｂ）に示すように、本発明による混合流体分離装置は、混合流体を通過させ比重差および水位差により各構成流体に分離させる水槽Ｚを使用する混合流体分離装置で、混合流体の流入口０１と、分離された比重の重い流体を流入口０１との水位差により排出する排出口０２と、分離された比重の軽い流体を貯留するため流入口０１側に設けられた主貯留部Ａ１および排出口０２側に設けられた副貯留部Ａ２とを備え、流入口０１から排出口０２に向かう混合流体をさえぎり水槽Ｚ内で溢流または伏流させる複数個の仕切り部Ｂ１、Ｂ２、Ｂ３、Ｂ４、Ｂ５と、混合流体から比重の軽い流体を分離浮上させるため排出口０２側が高く流入口０１側を低く傾斜させた複数個の傾斜部材ｆ、ｆ、…で構成する傾斜流路部０３と、主貯留部Ａ１に比重の軽い流体を導く分取口ａ１および副貯留部Ａ２に比重の軽い流体を導く分取口ａ２、ａ３と、主貯留部Ａ１から比重の軽い流体を回収するための回収口ｂとを設けたものである。
【００２７】
図１（ｂ）に示すように、仕切り部Ｂ１およびＢ４の底部は、水槽Ｚの底に連結され、仕切り部Ｂ４の上部は水槽Ｚの上部から乖離され、排出口０２に向う流体をさえぎりながら溢流させる高さに設定され、仕切り部Ｂ１の上部は流入口０１側にある傾斜流路部０３の底部に連結されている。仕切り部Ｂ２の底部は流入口０１側にある傾斜流路部０３の上部に連結され、上部は水槽Ｚの上部から乖離され、排出口０２に向う流体をさえぎりながら溢流させる高さに設定されている。仕切り部Ｂ３の底部は排出口０２側にある傾斜流路部０３の上部に連結され、上部は副貯留部Ａ２の底部に連結され、流体が排出口０２に向うのをさえぎり、流体を傾斜流路部０３へ導いている。仕切り部Ｂ５は上部が水槽Ｚの上部に連結され、下部は水槽Ｚから乖離している。
【００２８】
図２、図４に示すように、本発明による混合流体分離装置は、主貯留部Ａ１と回収部Ｋの間に設けられた回収口ｂに比重の軽い流体の回収液面高を調整する調整板Ｔを取付け、調整板Ｔに回収口ｂに相当する調整口Ｔｂを穿設し、調整板Ｔにエア駆動式エアシリンダーＳを連結して主貯留部Ａ１に比重の軽い流体が溜まったときにエア駆動式エアシリンダーＳを駆動して調整板Ｔを下げ、比重の軽い流体を調整口Ｔｂおよび回収口ｂから回収部Ｋを介して管Ｋ１より外部に回収するものである。
【００２９】
エアシリンダーＳは、水槽Ｚの上部に取付け台Ｓ０を設置して取付けられ、エアシリンダーＳの駆動軸Ｓ２に連結された調整板Ｔを上下動させる。調整板Ｔの素材としては、回収口ｂとの間で液漏れを生じることなく、かつ摩擦抵抗の少ない樹脂（ポリプロピレン、テフロン、デルリン、ポリエチレン）が好適である。
【００３０】
エアシリンダーＳのソケットＳ１に公知の電磁弁Ｖが接続され、電磁弁ＶにはツインタイマＷが接続され、主貯留部Ａ１に比重の軽い流体が溜まった時点でエアシリンダーＳを作動させる（図１（ｂ））。
【００３１】
複数個の分取口ａ１、ａ２、ａ３および回収口ｂの形状は、図１（ｂ）に示すように、水平方向に長軸を有する楕円形で、楕円形の短軸方向のうち底辺部にＶ字型の切り欠き０４を設ける。回収口ｂに当接する調整板Ｔの調整口Ｔｂにも対応する形体として底辺部にＶ字０４’が採用されている（図４）。
【００３２】
図１（ｂ）に示すように、混合流体から比重の軽い流体を分離浮上させる傾斜流路部０３は、排出口０２側を高く流入口０１側を低く傾斜させた平行な複数の傾斜部材ｆ、ｆ、…で構成され、傾斜部材ｆ、ｆ、…の下面ｆｕには、図３に示すように、比重の軽い流体の浮上を流入口０１側から排出口０２側に誘導する溝０５と、溝０５への比重の軽い流体の集合を誘導する複数の帯状板０６、０６、…とが設けられ、帯状板０６は溝０５に対して切妻屋根型（図３（ａ））または人字型（図３（ｂ））に鋭角をもって設けられている。
【００３３】
最も流入口０１側の傾斜部材ｆの下端部は仕切り部Ｂ１により水槽Ｚの底に連結され、排出口０２側に向って上向きに傾斜した最も流入口０１側の傾斜部材ｆの上端部は、排出口０２に向う流体をさえぎりながら溢流させる高さに設定された仕切り部Ｂ２に連結されている。最も排出口０２側の傾斜部材ｆの上部は仕切り部Ｂ３によって副貯留部Ａ２の下部に連結されている。傾斜流路部０３は原水中にあり、傾斜流路部０３を構成する傾斜部材ｆの傾斜角度θは、ストークスの原理により最適値が求められている。
油滴の浮上速度Ｖｔは、
【００３４】
【数１】

で与えられる。
【００３５】
Ｐｗ：水の密度
Ｐｏ：油の密度
Ｄｏ：油滴の直径
ｇ：重力の加速度
ｕ：水の絶対粘度
ここで、
Ｖｈ：水の径方向の流速
とすると、傾斜部材０３の傾斜角度θは、
【００３６】
【数２】

により求められる。
【００３７】
この傾斜角θを満たす傾斜部材ｆで構成される傾斜流路部０３内では原水に含まれる油滴は殆ど分離され、他の油滴と結合しながら浮上し、溝０５に対して切妻屋根型または人字型に鋭角をもって設けられた帯状板０６によって溝０５に誘導されながら上方へ集められて浮上する。
【００３８】
図１（ａ）に示すように、副貯留部Ａ２において貯留された比重の軽い流体を主貯留部Ａ１に還流させる誘導管ｄが、主貯留部Ａ１に併設された還流貯留室Ａ３の下部と副貯留部Ａ２の下部とを連結するかたちで水槽Ｚの外側に沿って設けられている。還流貯留室Ａ３の側部は孔ｙによって主貯留部Ａ１と連通している。
【００３９】
図１（ａ）および図２に示すように、主貯留部Ａ１において分離された比重の重い流体は、トラップ入り口０７から外設された逆流防止トラップｅを介して流入口０１に導かれる。主貯留部Ａ１から逆流防止トラップｅに至る間には、流体を伏流させるため下部が主貯留部Ａ１の底から乖離した仕切り部Ｂ６、Ｂ８、その間に流体を溢流させるため上部が水槽Ｚの上部から乖離した仕切り部Ｂ７が設けられ、逆流防止トラップｅのＵ字管を構成する混合流体分離装置Ｚ側にある入口管ｅ１と出口管ｅ２とには高低差を設け、出口管ｅ２が低く構成されている。
【００４０】
図１（ａ）、（ｂ）に示すように、水槽Ｚの流体面側には、流入口０１と主貯留部Ａ１の間の室Ｄ１、還流貯留室Ａ３と副貯留部Ａ２の間の室Ｄ２、副貯留部Ａ２と流体を溢流させるため上部が水槽Ｚの上部から乖離した仕切り部Ｂ４間の室Ｄ３と、仕切り部Ｂ４と流体を伏流させるため下部が水槽Ｚの底から乖離した仕切り部Ｂ５間の室Ｄ４、仕切り部Ｂ５と排出口０２間の室Ｄ５が形成される。これら各室Ｄ１、Ｄ２、Ｄ３、Ｄ４、Ｄ５、主貯留部Ａ１および副貯留部Ａ２のうち少なくとも流入口０１に連結された室Ｄ１の角面を曲面構造Ｒとする。
【００４１】
次に、本発明による混合流体分離装置の動作を説明する。
【００４２】
本発明による混合流体分離装置では、水槽Ｚの流体表面は多数の室に仕切られ、かつ水槽Ｚの上部から乖離した仕切り部Ｂ２、Ｂ４、下部が水槽Ｚの底から乖離した仕切り部Ｂ３、Ｂ５により、水槽Ｚ内を流入口０１から排出口０２に向う間に、流体は水槽Ｚ内を多数回上下流動させられて油水分離が促進される。
【００４３】
水槽Ｚ及び逆流防止トラップｅ内を精水で満たした後、水と油の混合した原水が流入口０１から供給される。原水内の比較的大きな油滴は、室Ｄ１で分離しつつ分取口ａ１から主貯留部Ａ１に流入する。分取口ａ１が水平方向に長軸を有する楕円形で、楕円形の短軸方向のうち底辺部にＶ字型の切り欠き０４を有する形状なので、切り欠き０４部分における表面張力で、粘度の高い流体、ゴミ等の回収効率が高まり、排出口０２に向かうべき流体の流入はわずかに押さえられる。
【００４４】
比較的小さな油滴を含む水は、主貯留部Ａ１の下を伏流して還流貯留室Ａ３の下に入り、仕切り部Ｂ１に遮られて仕切り部Ｂ２の上部を溢流し、傾斜流路部０３の上部より複数ある傾斜部材ｆの間を流下する。このとき、傾斜部材ｆの傾斜角θがストークスの原理によって設定されているので、残る比較的小さな油滴も徐々に傾斜流路部０３内で、水から分離され浮上する。
【００４５】
図３（ｂ）に示すように、傾斜流路部０３の下面ｆｕに設けられた溝０５と、溝０５に対して切妻屋根型または人字型に鋭角をもって設けられた帯状板０６によって、傾斜部材ｆのどの位置からも浮上する比重の軽い流体は溝０５に集合して効率的に分離が促進され、他の油滴と結合し大きな油滴となって分取口ａ２から副貯留部Ａ２に流入する。傾斜流路部０３は、排出口０２側を高く流入口０１側を低く傾斜させた平行な１８枚の２ｃｍ間隔の傾斜部材ｆで構成されているので、原水は、流入口０１から排出口０２へ向うのとは実質的に逆の流れとなり、装置内において油水分離のために好適な時間がかけられている。
【００４６】
傾斜流路部０３を流下した水は副貯留部Ａ２の下を伏流し仕切り部Ｂ３に遮られて仕切り部Ｂ４を上昇し、室Ｄ４に流入する。このとき残りの油滴は分取口ａ３から副貯留部Ａ２に流入する。油滴がほとんど分離回収された残りの水は仕切り部Ｂ５を伏流して室Ｄ５に入り上昇して排出口０２から排出される。
【００４７】
室Ｄ２、Ｄ３において分離浮上し分取口ａ２、ａ３から副貯留部Ａ２に入った油滴は、水槽Ｚに沿って外設された誘導管ｄを介して還流貯留室Ａ３に送られる。還流貯留室Ａ３に入った油滴は孔ｙを通り主貯留部Ａ１に流入する。
【００４８】
主貯留部Ａ１に比重の軽い流体が溜まったら、エアシリンダーＳを駆動して調整板Ｔを下げ、調整口Ｔｂを回収口ｂにあわせて油を回収部Ｋに流入させ、管Ｋ１より外部に回収する。主貯留部Ａ１に比重の軽い流体が溜まるまでは調整板Ｔによって回収口ｂは封じられている。
【００４９】
エアシリンダーＳのソケットＳ１には、公知の電磁弁Ｖが接続され、電磁弁ＶにはツインタイマＷが接続されているので、主貯留部Ａ１に油が溜まる時間をあらかじめセットし、主貯留部Ａ１に油が溜まった時にのみエアシリンダーＳを作動させ、溜まった油を回収する。
【００５０】
主貯留部Ａ１には比重の軽い流体と共に比重の重い流体も少しずつ溜まる。溜まった比重の重い流体は、図２に示すように、仕切り部Ｂ６、Ｂ７、Ｂ８によって伏流、溢流、伏流と動きを妨げられながら水槽上部から逆流防止トラップｅの入口管ｅ１に送られ、出口管ｅ２からは、直接あるいは消泡器等（図示せず）を介して流入口０１に導かれ、わずかに油分を含む流体はエンドレスに処理される。この逆流防止トラップｅを接続することによって、主貯留部Ａ１の液体をエンドレス処理して流入口０１に導くにあたり、混合流体分離装置にエアー式ダイヤフラムポンプを接続したとき、液体が混合流体分離装置に逆流するのを防止し、分離しきれない混合流体を脈動なく送り出すことができる。
【００５１】
本発明による混合流体分離装置は、混合流体の比重差および水位差により前記混合流体を各構成流体に分離させるため、流入口０１は排出口０２より高く、仕切り部Ｂ４はその間の高さであり、また、逆流防止トラップｅの入口管ｅ１に向かうトラップ入り口０７は流入口０１より低く、構成されている。
【００５２】
本発明による混合流体分離装置では、水槽Ｚの混合流体の面が仕切られた各室、貯留部および副貯留部のうち少なくとも流入口に連結された室Ｄ１の角面を曲面構造Ｒとするので、流入口０１から流入した混合流体の比重の軽い流体は、室Ｄ１の４隅に付着することなく、混合流体として室Ｄ２にスムーズに流動する。
【００５３】
本発明による混合流体分離装置で、一日５回、強制的に１回１０秒間、主貯留部Ａ１から油を回収したところ、５００ｃｃ中油以外の液体（水）は１０ｃｃしか含まれず、非常に効率よく混合流体を分離回収できることが確認された。
【００５４】
上記説明では、混合流体の構成流体を、水と油としたが、これに限定されず、切削油と防錆油の混合油等他の比重の異なる混合流体にも好適である。
【００５５】
【発明の効果】
以上の実施例からも明らかなように、本発明による混合流体分離装置は、回収口に比重の軽い流体の回収液面高を調整する調整板を取付け、調整板に回収口に相当する調整口を穿設し、調整板にエア駆動式エアシリンダーを連結して主貯留部に比重の軽い流体が溜まったときにエア駆動式エアシリンダーを駆動して調整板を下げ比重の軽い流体を調整口および回収口から回収し、傾斜流路部を構成する傾斜部材の下面には、比重の軽い流体の浮上を流入口側から排出口側に誘導する溝と、溝への比重の軽い流体の集合を誘導する複数の帯状板とが設けられ、帯状板は溝に対して切妻屋根型または人字型に鋭角をもって設け、副貯留部に流入した比重の軽い流体を誘導管を介して主貯留部に還流させ、主貯留部において分離された比重の重い流体を外設された逆流防止トラップを介して流入口に導き、流入口に連結された室の角面を曲面構造とするもので、装置を設置配管後は動力源、フィルター、吸着剤等一切使用せず、効率良く油分を分離できると共に、排水には油分を流出せず、非常に経済的で、設置スペースも最小限に押えられる。

[Industrial application fields]
The present invention relates to a mixed fluid separation device, and more particularly to a mixed fluid separation device suitable for separation of fluid mixtures having different specific gravities such as waste water containing waste oil in various factories, mixed oil of cutting oil and rust preventive oil, and the like.
[0002]
[Prior art]
Conventionally, each component is separated, recovered, and removed from wastewater containing waste oil, mixed oil of cutting oil and rust preventive oil, etc. in machine factories, gas stations, metal surface treatment factories, food processing factories, etc. There was a special device.
[0003]
(1) Mechanical mixed fluid separator, electrical mixed fluid separator, or mixed fluid separator using solvent, flocculant, adsorbent or filter.
[0004]
However, the separation device of (1) has the disadvantages that the device itself is expensive and expensive to operate, and clogging, failure occurs, and the oil concentration in the drainage (hereinafter referred to as raw water load) is narrow. . As a solution,
(2) In order to separate mixed fluids having different specific gravities, an economical oil / water separation method (Japanese Patent Laid-Open No. 52-1111060) and ( 3) An oil-water specific gravity difference separator (Japanese Patent Laid-Open No. 53-97670) has been proposed.
[0005]
[Problems to be solved by the invention]
The oil-water separation method (2) (Japanese Patent Laid-Open No. 52-1111060) utilizing the specific gravity difference and water level difference of the mixed fluid does not use power, and the oil-water separation is performed by the difference in specific gravity and water level between oil and water. The oil was recovered, no breakdown occurred, it was able to cope with fluctuations in the raw water load, and the operating cost was low. However, multiple swash plates (gallery) for promoting separation of oil and water flowed the raw water. Therefore, the flow of raw water becomes smooth, and as a result, the oil-water separation is incomplete and the apparatus is too large.
[0006]
Further, the oil-water specific gravity difference separation device (Japanese Patent Laid-Open No. 53-97670) provided with the wavyly bent separation plate (3) complicates the structure in the gallery, reduces the size of the device, and separates the oil-water separation. However, since the bent separating plate in the gallery is complicated and excessive, there is a disadvantage that the gallery functions only partially.
[0007]
Furthermore, regarding the oil recovery section, in both (2) and (3), the large oil droplets that floated and the oil droplets separated by the gallery float up and are collected in the oil sump chamber. There was also a problem that the oil was discharged from the outlet without being collected.
[0008]

[0013]
However, the separation port 5 that guides the separated light fluid with a specific gravity to the storage unit G, the plurality of separation ports 6 and 7 that guide the fluid to the storage unit H, and the separation port 8 from the storage unit G to the storage unit K, Although the fine adjustment of bolting the height of the separation port 285 from the remaining separation unit 282 to the storage unit 284 according to the processing flow rate is performed, there are many separation ports, so there is a difficulty that it takes time for adjustment. In addition, since all the dispensing ports are fixed by bolting, there is a problem that a fluid having a high specific gravity flows in due to a change in the liquid amount. Since the shape of the sorting port is substantially circular, if the height is adjusted to a position where high-viscosity fluid, dust, or the like is collected, there is a difficulty in that the amount of fluid collected toward the discharge port 12 increases.
[0014]

[0016]
The drainage in the guide pipe 281 sent from the storage part G on the inlet 11 side to the outlet 12 contains about 10 percent of a light fluid with a specific gravity that cannot be separated, and the separation efficiency was lowered.

[0039]
As shown in FIGS. 1A and 2, the heavy fluid separated in the main reservoir A <b> 1 is led from the trap inlet 07 to the inflow port 01 through the backflow prevention trap e. Between the main reservoir A1 and the backflow prevention trap e, the lower part is separated from the bottom of the main reservoir A1 in order to cause the fluid to flow down, and the upper part is in the tank Z to overflow the fluid between them.

Among these chambers D1, D2, D3, D4, D5, the main reservoir A1 and the sub reservoir A2, at least the corner surface of the chamber D1 connected to the inflow port 01 is defined as a curved surface structure R.
[0041]
Next, the operation of the mixed fluid separator according to the present invention will be described.
[0042]
In the mixed fluid separator according to the present invention, the fluid surface of the water tank Z is partitioned into a number of chambers, and the partition parts B2 and B4 are separated from the upper part of the water tank Z, and the partition parts B3 and B5 are separated from the bottom of the water tank Z. Thus, while the water tank Z moves from the inflow port 01 toward the discharge port 02, the fluid is caused to flow up and down many times in the water tank Z, and oil-water separation is promoted.
[0043]
After filling the water tank Z and the backflow prevention trap e with purified water, raw water mixed with water and oil is supplied from the inflow port 01. The relatively large oil droplets in the raw water flow into the main reservoir A1 from the sorting port a1 while being separated in the chamber D1. Since the sorting port a1 has an elliptical shape having a major axis in the horizontal direction and a shape having a V-shaped notch 04 at the bottom of the minor axis direction of the ellipse, the surface tension at the notch 04 portion causes the viscosity to be reduced. The recovery efficiency of high fluid, dust, etc. is increased, and the inflow of the fluid to be directed to the discharge port 02 is slightly suppressed.
[0044]
Water containing relatively small oil droplets flows down under the main storage part A1 and enters under the reflux storage chamber A3, is blocked by the partition part B1 and overflows the upper part of the partition part B2, and the inclined channel part 03 It flows down between a plurality of inclined members f from the upper part. At this time, since the inclination angle θ of the inclined member f is set according to the Stokes principle, the remaining relatively small oil droplets gradually separate from the water and float in the inclined flow path portion 03.
[0045]
As shown in FIG. 3B, the groove 05 provided on the lower surface fu of the inclined channel portion 03 and the belt-like plate 06 provided with a gable roof shape or a human character shape with an acute angle with respect to the groove 05 are inclined. The fluid having a low specific gravity that floats from any position of the member f is gathered in the groove 05 to be efficiently separated, and is combined with other oil droplets to form large oil droplets from the sorting port a2 to the auxiliary reservoir A2. Flow into. The inclined channel portion 03 is composed of 18 parallel inclined members f having an interval of 2 cm, with the discharge port 02 side being high and the inflow port 01 side being low, so that the raw water flows from the inflow port 01 to the discharge port 02. The flow is substantially opposite to the direction of the flow, and a suitable time is taken for oil-water separation in the apparatus.
[0046]
The water flowing down the inclined channel portion 03 flows down under the auxiliary storage portion A2, is blocked by the partition portion B3, rises up the partition portion B4, and flows into the chamber D4. At this time, the remaining oil droplets flow into the auxiliary reservoir A2 from the sorting port a3. The remaining water from which most of the oil droplets have been separated and collected flows down through the partition portion B5, enters the chamber D5, and is discharged from the discharge port 02.
[0047]
The oil droplets separated and floated in the chambers D2 and D3 and entered the sub-reservoir A2 from the sorting ports a2 and a3 are sent to the reflux storage chamber A3 via the guide pipe d provided along the water tank Z. The oil droplets entering the reflux storage chamber A3 pass through the hole y and flow into the main storage portion A1.
[0048]
When a fluid with a low specific gravity accumulates in the main reservoir A1, the air cylinder S is driven to lower the adjustment plate T, the adjustment port Tb is aligned with the recovery port b, and the oil is allowed to flow into the recovery unit K. to recover. The recovery port b is sealed by the adjustment plate T until a fluid having a low specific gravity is accumulated in the main reservoir A1.
[0049]
Since a known solenoid valve V is connected to the socket S1 of the air cylinder S, and a twin timer W is connected to the solenoid valve V, a time for oil to accumulate in the main reservoir A1 is set in advance, and the main reservoir The air cylinder S is operated only when oil has accumulated in A1, and the accumulated oil is recovered.
[0050]
In the main reservoir A1, a fluid with a high specific gravity and a fluid with a high specific gravity accumulate little by little. As shown in FIG. 2, the accumulated fluid with a high specific gravity is sent to the inlet pipe e1 of the backflow prevention trap e from the upper part of the water tank while being blocked by the partitioning parts B6, B7, B8 and the movement of the downflow, the overflow, and the downflow. From the outlet pipe e2, the fluid is guided to the inlet 01 directly or via a defoamer or the like (not shown), and the fluid containing a small amount of oil is processed endlessly. By connecting the backflow prevention trap e, the liquid in the main reservoir A1 is endlessly processed and led to the inlet 01. When an air diaphragm pump is connected to the mixed fluid separator, the liquid is supplied to the mixed fluid separator. It is possible to prevent the reverse flow and to feed the mixed fluid that cannot be separated without pulsation.
[0051]
In the mixed fluid separation device according to the present invention, the mixed fluid is separated into the constituent fluids by the specific gravity difference and the water level difference of the mixed fluid. Therefore, the inlet port 01 is higher than the outlet port 02, and the partition B4 is at a height therebetween. The trap inlet 07 toward the inlet pipe e1 of the backflow prevention trap e is configured to be lower than the inlet 01.
[0052]
In the mixed fluid separation device according to the present invention, the curved surface structure R is defined as the square surface of the chamber D1 connected to at least the inlet of each of the chambers, the storage unit, and the auxiliary storage unit in which the surface of the mixed fluid of the water tank Z is partitioned. The fluid having a light specific gravity of the mixed fluid flowing in from the inflow port 01 flows smoothly into the chamber D2 as a mixed fluid without adhering to the four corners of the chamber D1.
[0053]
In the mixed fluid separation device according to the present invention, when oil is forcibly collected from the main reservoir A1 5 times a day for 10 seconds once, only 10 cc of liquid (water) other than 500 cc of oil is contained, which is very efficient. It was confirmed that the mixed fluid can be separated and recovered well.
[0054]
In the above description, water and oil are used as constituent fluids of the mixed fluid. However, the present invention is not limited to this, and is suitable for other mixed fluids having different specific gravity, such as a mixed oil of cutting oil and rust preventive oil.
[0055]
【The invention's effect】
As is clear from the above embodiments, the mixed fluid separation device according to the present invention is provided with an adjusting plate for adjusting the recovered liquid level of a light fluid having a low specific gravity, and an adjusting port corresponding to the collecting port. When an air-driven air cylinder is connected to the adjustment plate and fluid with a low specific gravity accumulates in the main reservoir, the air-driven air cylinder is driven to lower the adjustment plate and adjust the fluid with a low specific gravity. In addition, on the lower surface of the inclined member that constitutes the inclined channel portion that is collected from the recovery port, a groove that guides the rising of the light fluid with a low specific gravity from the inlet side to the outlet side, and a collection of the low specific gravity fluid in the groove A plurality of belt-like plates are provided, and the belt-like plates are provided with a gable roof type or a human character shape with an acute angle with respect to the groove, and a fluid having a low specific gravity flowing into the sub-reservoir is passed through the guide pipe Heavy flow separated into the main reservoir Is connected to the inlet through an external backflow prevention trap, and the corner surface of the chamber connected to the inlet has a curved structure. After installing the equipment, the power source, filter, adsorbent, etc. are used at all In addition, oil can be separated efficiently, oil does not flow into the drainage, and it is very economical and installation space can be kept to a minimum.
