Description

【０００１】
【発明の属する技術分野】
本発明は油水分離回収装置、特に、油水の比重差を利用した油水分離回収装置に関するものである。
【０００２】
【従来の技術】
従来、飲食店、特に、らーめん店の使用済みの排出水には油分が多く含まれており、油水の分離回収装置を通して油分を分離回収する必要がある。この油分の分離には、水と油の比重差を利用したものが多い。
【０００３】
【発明が解決しようとする課題】
然しながら、このような油は、温度による粘土性変化が激しく、また、油分以外にも雑物などの固形不純物が混入し浮遊しているので比重差のみによって完全に回収するのは非常に難しい。
【０００４】
本発明は上記の欠点を除くようにしたものである。
【０００５】
【課題を解決するための手段】
本発明の油水分離回収装置は、処理水槽と、この処理水槽に油水混合液を導入する手段と、上記処理槽の下部に配置した発熱手段と、上記処理槽の下部に連通せしめた排油手段及び排水手段とより成ることを特徴とする。
【０００６】
また、本発明の油水分離回収装置は、処理水槽と、この処理水槽を油水混合液導入側と排油側の２部分に分離区劃する手段と、上記油水混合液導入側に配置した油水混合液導入手段、加熱手段、水道水導入手段、油分を上方にガイドするガイド手段及び排水手段と、上記排油側に設けた貯油部分及び排油手段とより成ることを特徴とする。
【０００７】
また、本発明の油水分離回収装置は、処理水槽と、この処理水槽を油水混合液導入側と排油側の２部分に分離区劃する手段と、上記油水混合液導入側に配置した油水混合液導入手段、加熱手段、油分を上方にガイドするガイド手段及び水道水導入手段と、上記排油側に設けた貯油部分、排油手段及び排水手段とより成ることを特徴とする。
【０００８】
【発明の実施の形態】
以下図面によって本発明の実施例を説明する。
【０００９】
本発明の第１の実施例においては図１に示すように処理水槽１の上部にホッパー２を設けて処理水槽１内の油水混合液を投入できるようにし、上記処理水槽１の底面上に発熱体３を配置し、上記処理水槽１の底面と側面下部に夫々排水弁４を有する排水パイプ５と、排油弁６を有する排油パイプ７とを設ける。
【００１０】
なお、８は処理水槽１内上部に設けた水位の上限設定センサー、９は処理水槽１内下部の上記発熱体３より上方位置に設けた水位の下限設定センサー、１０は排油貯槽である。
【００１１】
本発明の第１の実施例は上記のような構成であるから処理水槽１内に投入された油水混合液中の油は水との比重の差により分離浮上するばかりでなく、発熱体３によって例えば４３℃に加熱されるため油の浮上が促進され、ポンプ等の動力源を用いることなく油水分離が効果的に行われる。
【００１２】
従って油水混合液が上限設定値に達してから所定時間後排水弁４を開いて処理水槽１内下部の水を排水パイプ５を介して排水し、水位が下限設定値に達したとき、上記排水弁４を閉じ、排油パイプ７を介して排油貯槽１０内に処理水槽１内上部の油を排油する。排油終了後は排油弁６を閉じ、新たな油水混合液をホッパー２を介して処理水槽１内に導入し、以下上記のサイクルを繰り返すようにする。
【００１３】
図２は本発明の第２の実施例を示し、図１と同一部分には同一符号を付し、その詳細な説明は省略する。この第２の実施例においては処理水槽１内を、下部開口１１ａとより成るこの下部開口１１ａを塞ぐ位置でこれから離間して処理水槽１の下面から垂立したついたて板１１ｂとより成る仕切り板１１によって油水混合液導入側１ａと排油側１ｂの２部分に分離区劃せしめ、この排油側１ｂ内上部に貯油槽１２を設け、下部にフィルター１３を介して排油パイプ７を開口し、上記油水混合液導入側１ａ内の上昇油分を垂立する油通路１４を介して上記排油側１ｂの排油槽１２内に投入できるようにすると共に、ホッパー２の下端開口をシリンダー１５によって開閉制御される蓋１６によって塞ぎ、上記貯油槽１２の下面をシリンダー１７によって開閉制御される蓋１８によって塞ぎ、混合液導入側１ａ内下部に給水弁１９を介して給水パイプ２０を接続する。
【００１４】
この第２の実施例においては、シリンダー１５によってホッパー２の蓋１６を開き、貯油槽１２の蓋１８を閉じた状態でホッパー２を介して油水混合液を処理水槽１の油水混合液導入側１ａ内に投入し、油水混合液が上限設定値に達してから所定時間後蓋１６を閉じ、給水弁１９を開いて水道水を給水パイプ２０を介して処理水槽１内に導入し、上部に分離された油を水道水の水圧で油通路１４内に上昇せしめて貯油槽１２内に投入せしめる。
【００１５】
貯油槽１２内の油が所定量に達した後は、給水弁１９を閉じ排水弁４を開いて処理水槽１内の水を排水パイプ５を介して排水する。処理水槽１内の水位が下限設定値に達したとき排水弁４を閉じ、シリンダー１７によって排油槽１２の下面の蓋１８を開いて貯油槽１２内の油をフィルター１３を介して排油パイプ７から排油せしめる。この場合、排油側１ｂに落下した油はついたて板１１ｂの作用により油水混合液導入側１ａ内に還流されることはない。
【００１６】
図３は本発明の第３の実施例を示し、上記各実施例と同一部分には同一符号を付し、その詳細な説明は省略する。
【００１７】
この第３の実施例においては処理水槽１の上部に頂部開口を有するファンネル２１を配置し、発熱体３は処理水槽１の中間の高さに配置し、処理水槽１内は、処理水槽１の底面との間に僅かな隙間２２が形成されるように垂立せしめた仕切板２３によって仕切る。
【００１８】
また、処理水槽１内の排油側１ｂの下部にはフィルター１３を介して排水パイプ２４を開口し、上記ファンネル２１の上部に排油槽１２を形成し、この排油槽１２には排油パイプ７を開口せしめ、この開口には開閉蓋２５を設け、これをシリンダー２６によって常時閉じるように制御する。
【００１９】
更に、処理水槽１内には上記隙間２２を塞ぐ位置で略排水パイプ２４の高さに達するよう互いに離間して処理水槽１の底面から垂立する複数の隔壁２７ａ，２７ｂを設け、水位センサー２８を上記ファンネル２１の頂部開口に配置し、この水位センサー２８が作動したとき上記開閉蓋２５を開くようにする。
【００２０】
なお、上記仕切板２３は断熱材によって構成し、加熱された油水混合液の熱によってシリンダー２６が劣化しないようにするのが好ましい。
【００２１】
この第３の実施例においては排油パイプ７の開口をシリンダー２６によって開閉制御される蓋２５によって塞ぎ、排水パイプ２４を閉じ、ホッパー２を介して油水混合液を処理水槽１内に投入し、油水混合液が上限設定値に達してから所定時間後水道水を給水パイプ２０を介して処理水槽１内に導入し、上方に分離された油を水道水の水圧でファンネル２１の開口を超えるよう上昇せしめて貯油槽１２内に貯溜せしめる。処理水槽１内の水位が水位センサー２８に達した後は、給水パイプ２０を閉じ、排油パイプ７の開閉蓋２５を開いて貯油槽１２内の油を排油パイプ７から排油する。その後排水パイプ２４を開けば、処理水槽１内の水は排水パイプ２４を介して排水される。処理水槽１内の水位は隔壁２７ａ，２７ｂ以下となることはない。
【００２２】
また、排水パイプ２４側に落下した油は隔壁２７ａ，２７ｂの作用により油水混合液導入側内に還流されることはない。
【００２３】
なお、本発明においては油水混合液が必要以上に加熱されて固まることがないよう温度センサーを用い制御するのが好ましい。
【００２４】
【発明の効果】
上記のように本発明の油水分離回収装置によれば油と水をその比重差と加熱によって分離浮上せしめるようにしたので揚水用ポンプ等が不要となる大きな利益がある。
