【００３５】
【発明の実施の形態】
以下、この発明の廃油処理再資源化システム及び廃油処理再資源化装置の実施の形態を、図面に基づいて説明するが、この発明は、この実施の形態に限定されない。
【００３６】
図１は廃油処理再資源化システム及び廃油処理再資源化装置の概略図である。この実施の形態の廃油処理再資源化システム１は、濾過工程Ａと、保管工程Ｂと、混合工程Ｃとを有する。
【００３７】
濾過工程Ａは廃油に混入されている不純物を濾過する。この濾過工程Ａには、濾過ポンプＰ１、濾過室１０が配置されている。廃油となった灯油、軽油、ナフサ等をタンクローリ２にて回収し、受入口１１に接続し、タンクローリ２に設置したポンプにより廃油を供給経路１２を介して濾過室１０に送られる。この供給経路１２には、濾過ポンプＰ１、バルブＶ１〜Ｖ３が配置されている。
【００３８】
タンクローリ２にて回収した廃油は、地下保管タンクに保管する場合は、濾過ポンプＰ１を使用する場合と使用しない場合がある。濾過ポンプＰ１を使用しない場合は、バルブＶ１，Ｖ３を閉じ、バルブＶ２を開き、濾過ポンプＰ１を駆動しないで、タンクローリ２に設置したポンプにより廃油を送る。濾過ポンプＰ１を使用する場合は、バルブＶ２を閉じ、バルブＶ１，Ｖ３を開き、濾過ポンプＰ１を駆動する。
【００３９】
濾過室１０には、自動ストレーナＦ１、濾過器Ｆ２，Ｆ３が配置され、さらにバルブＶ４〜Ｖ８が配置されている。また、濾過室１０の前後には、圧力計ＰＧ１，ＰＧ２が配置され、さらに自動ストレーナＦ１と濾過器Ｆ２の間には圧力計ＰＧ３が配置され、濾過器Ｆ２と濾過器Ｆ３との間には圧力計ＰＧ４が配置されている。
【００４０】
自動ストレーナＦ１は、濾過器Ｆ２，Ｆ３の濾過材の耐久性の延長及び保護する。また、濾過器Ｆ２，Ｆ３は、廃油に混入しているゴミ類の不純物を濾過して清浄な油に再生する。圧力計ＰＧ１〜ＰＧ４は、自動ストレーナＦ１、濾過器Ｆ２，Ｆ３の濾過材の詰まり状態を計測する。即ち、圧力計ＰＧ１と圧力計ＰＧ３の圧力差（以下差圧という）が大きくなると自動ストレーナＦ１が詰まり、圧力計ＰＧ３の圧力と圧力計ＰＧ４の差圧が大きくなると濾過器Ｆ２が詰まり、圧力計ＰＧ４の圧力と圧力計ＰＧ２の差圧が大きくなると濾過器Ｆ３が詰まり、この濾過器Ｆ２，Ｆ３の濾過材の詰まり状態を計測すると、濾過材の交換を行う。
【００４１】
濾過器Ｆ２の濾過材の交換は、バルブＶ４，Ｖ５を閉じて行ない、濾過器Ｆ３の濾過材の交換は、バルブＶ５，Ｖ６を閉じて行なう。また、バルブＶ７を開けて濾過器Ｆ２のドレンを排出し、バルブＶ８を開けて濾過器Ｆ３のドレンを排出する。
【００４２】
この実施の形態では、濾過工程Ａに、自動ストレーナＦ１、濾過器Ｆ２，Ｆ３を備え、濾過器Ｆ２の濾過材より濾過器Ｆ２の濾過材をメッシュを小さくし、廃油を複数段階で順次濾過精度を上げることで、微細な不純物まで除去でき品質の良い清浄油を得ることができる。
【００４３】
保管工程Ｂには、地下保管タンク２０を備え、濾過工程Ａで混入しているゴミ類等の不純物を除去した清浄油を混合工程Ｃに送る前に保管する。地下保管タンク２０は、中仕切り２１，２２で３区分されている。区分室２０ａの前後には、バルブＶ１０，１１が設けられ、区分室２０ｂの前後には、バルブＶ１２，１３が設けられ、区分室２０ｃの前後には、バルブＶ１４，１５が設けられ、例えば灯油の清浄油、軽油の清浄油、ナフサの清浄油を区分して区分室２０ａ，２０ｂ，２０ｃに保管する。区分室２０ａ，２０ｂ，２０ｃには、油面計２３〜２５が備えられ、保管量の表示を行なう。さらに、
地下保管タンク２０には、エアー抜き２６が備えられ、このエアー抜き２６により自然気化物を放出し、地下保管タンク２０内を常圧に維持する。
【００４４】
地下保管タンク２０に保管される清浄油は、移送経路Ｄにより送られる。移送経路Ｄには、移送ポンプＰ２、バルブＶ３０〜Ｖ３４、流量計ＦＭ１が備えられている。バルブＶ３４を閉じ、バルブＶ３３を開き、移送ポンプＰ２を駆動することで、地下保管タンク２０に保管される清浄油が出荷される。
【００４５】
一方、バルブＶ３３を閉じ、バルブＶ３４を開き、移送ポンプＰ２を駆動することで、地下保管タンク２０に保管される清浄油を混合工程Ｃへ送られる。
【００４６】
このバルブＶ３３とバルブＶ３４とで、混合工程Ｃへ送る経路と混合工程Ｃへ送らないで出荷する経路との切り換えを行なう切換手段が構成される。
【００４７】
また、この実施の形態では、濾過工程Ａに清浄油を循環するさせる循環経路Ｅを備えることができる。この循環経路Ｅには、バルブＶ４０，Ｖ４１が備えられ、バルブＶ４０，Ｖ４１を開き、バルブＶ３２，Ｖ４を閉じ、移送ポンプＰ２を駆動することで、地下保管タンク２０に保管される清浄油が濾過器Ｆ２の前段に移送される。このように、濾過工程Ａに清浄油を循環するさせることで、微細な不純物まで除去でき品質の良い清浄油を得ることができる。
【００４８】
流量計ＦＭ１は、０戻し付きの積算表示であり、混合工程Ｃでの混合量は、例えば再生油の１０％が適量である。この混合量を計測するために、流量計ＦＭ１に積算表示が付属していることで、混合量の記録が作成される。
【００４９】
混合工程Ｃは、混合器３０が配置され、不純物が除去された清浄油に再生油及び／又は混合物として高粘度油を混合して再生燃料油を得る。この混合器３０には、攪拌機３１、エアー抜き３２、油面計３３が備えられている。攪拌機３１は、再生油及び高粘度油と清浄油がよりよく混合するように強制攪拌する。エアー抜き３２は、自然気化物を放出し、混合器３０内を常圧に維持する。油面計３３は、再生油及び高粘度油の混合量を計測し、また再生燃料油の保管量の表示を行なう。
【００５０】
高粘度油は、特殊な高温溶解機器４０（スチームで加温）で溶解して混合する。高粘度油（固形状のものも含む）は混合器３０で、他の液状物と混ざり切れない場合があるため、高温溶解機器４０で溶解して混合し易く、また混合した後液体中で粒状固形に戻るのを防止する。この高粘度油は、粘度の高い油脂類例えばグリス、ワックス等、通常燃料としては不向きなものであり、温度をかけて溶融し粘度調整する。
【００５１】
この混合工程Ｃでは、不純物が除去された清浄油に応じて再生油及び高粘度油の混合量を決定して混合し、この混合工程Ｃで粘度等一定化した再生油を製造、また低カロリー焼却物と混合しての燃焼し易い再生燃料油を製造することができる。
【００５２】
混合器３０に保管される再生燃料油は、出荷経路Ｆにより送られる。出荷経路Ｆには、出荷ポンプＰ３、流量計ＦＭ２、バルブＶ５０〜Ｖ５２が配置されている。バルブＶ５１を閉じ、バルブＶ５０，Ｖ５２を開き、出荷ポンプＰ３を駆動することで、タンクローリ２に再生燃料油を積み込み、タンクローリ２で顧客へ配送する。流量計ＦＭ２は、０戻し付きの積算表示であり、タンクローリ２への積み込み量の計測を行なう。積算表示が付属していることで、出荷量の記録を作成することができる。
【００５３】
図２は廃油処理再資源化のフローチャートである。この実施の形態の廃油処理再資源化システムでは、まず、タンクローリ２により排出事業者（ステップａ１）から廃油を回収し（ステップｂ１）、廃油処理再資源化システム１に受け入れる（ステップｃ１）。濾過ポンプＰ１の駆動で（ステップｄ１）、廃油を濾過室１０に移送し、この濾過室１０に配置される自動ストレーナＦ１、濾過器Ｆ２，Ｆ３で濾過を行ない、廃油に混入されている不純物が除去された清浄油を得る（ステップｅ１）。
【００５４】
この清浄油を地下保管タンク２０に保管し（ステップｆ１）、移送ポンプＰ２を駆動することで（ステップｇ１）、地下保管タンク２０に保管される清浄油を混合工程Ｃへ送らないで出荷する（ステップｈ１）。
【００５５】
一方、混合工程Ｃへ移送して不純物が除去された清浄油に再生油及び高粘度油を混合して再生燃料油を得え（ステップｉ１）、この再生燃料油を製品として出荷し（ステップｊ１）、廃油を焼却する等資源を無駄にすることなく、有効活用することができる。
【００５６】
この実施の形態では、廃油となった灯油、軽油、ナフサ等の処理について説明したが、その他の多油分、少油分廃液も同様に処理でき、その他の多油分、小油分廃液は、切替弁Ｖ６０により濾過工程Ａから保管工程Ｂを経ないで混合工程Ｃへ送られて処理される。
【００５７】
図３は廃油処理再資源化システム及び廃油処理再資源化装置の他の実施の形態の概略図である。この実施の形態は、図１の混合工程Ｃにおいて、混合器３０に代えて、混合器６０と攪拌タンク７０とを配置したものであり、他の構成は同様に構成されるので同じ符号を付して説明を省略する。
【００５８】
この実施の形態では、混合工程Ｃで製品助燃油のカロリーを定め、不純物が除去された清浄油に応じて複数の混合物を選択し、目標カロリーに合うように混合器６０で混合する。複数の混合物として、例えば油泥、多油分排水、小油分排水、高粘度油等を用いることができ、産業廃棄物となっている燃焼可能な廃棄物を低カロリー助燃油としてリサイクルさせるのに好ましい。
【００５９】
この混合の後、攪拌タンク７０で再生油と混合攪拌し、混合された製品は攪拌タンク７０で確認され、目標カロリー値と差がある場合には、循環ポンプＰ１０を駆動して混合器６０へ戻して目標カロリー値になるように複数の混合物を選択して混合し、再調整されて再生燃料油を得ることができ、製品タンク８０は例えば２基準備し、低カロリーと高カロリー製品に区分して保管する。
【００６０】
図４は廃油処理再資源化の他の実施の形態のフローチャートである。この実施の形態の廃油処理再資源化システムでは、まず、タンクローリ２により排出事業者（ステップａ２）から廃油を回収し（ステップｂ２）、廃油処理再資源化システム１に受け入れ、濾過ポンプＰ１の駆動で、廃油を濾過室１０に移送し、この濾過室１０に配置される自動ストレーナＦ１、濾過器Ｆ２，Ｆ３で濾過を行ない（ステップｃ２）、廃油に混入されている不純物が除去された清浄油を得て、この清浄油を地下保管タンク２０に保管する（ステップｄ２）。移送ポンプＰ２を駆動することで、地下保管タンク２０に保管される清浄油を混合工程Ｃへ送らないで出荷する（ステップｅ２）。
【００６１】
一方、混合工程Ｃへ移送して不純物が除去された清浄油は、混合器６０に送られ、この混合器６０で複数の混合物を選択し目標カロリーに合うように混合する（ステップｆ２）。
【００６２】
混合物が複数でありその性状は多種類である。また混合した後混合物が分離する様ならば安定したカロリーとならないため、この混合の後、攪拌タンク７０で再生油と混合攪拌し、目標カロリー値と差がある場合には、循環ポンプＰ１０の駆動により混合物の混合へ戻して目標カロリー値になるように混合する（ステップｇ２）。この循環ポンプＰ１０は、例えば粉砕刃を保有しポンプ・ミキサー能力と、せん断能力を兼ね備えた温式微粉砕機（三井鉱山製：トリゴナルマシン）を主体とした混合装置である。
【００６３】
製品タンクは複数基準備し、低カロリーと高カロリー製品に区分して保管する（ステップｈ２）。
【００６４】
この実施の形態でも、廃油となった灯油、軽油、ナフサ等の処理について説明したが、その他の多油分、小油分廃液も同様に処理できるが、その他の多油分、小油分廃液は、切替弁Ｖ６０により濾過工程Ａから保管工程Ｂを経ないで混合工程Ｃへ送られて処理される。

In this supply path 12, a filtration pump P1 and valves V1 to V3 are arranged.
[0038]
When the waste oil collected by the tank lorry 2 is stored in an underground storage tank, the filtration pump P1 may or may not be used. When the filtration pump P1 is not used, the valves V1 and V3 are closed, the valve V2 is opened, and the waste oil is sent by the pump installed in the tank lorry 2 without driving the filtration pump P1. When using the filtration pump P1, the valve V2 is closed, the valves V1 and V3 are opened, and the filtration pump P1 is driven.
[0039]

A pressure gauge PG4 is provided.
[0040]
The automatic strainer F1 extends and protects the durability of the filter media of the filters F2 and F3. In addition, the filters F2 and F3 filter impurities of garbage mixed in the waste oil to regenerate the clean oil. The pressure gauges PG1 to PG4 measure the clogged state of the filter materials of the automatic strainer F1 and the filters F2 and F3. That is, when the pressure difference between the pressure gauges PG1 and PG3 (hereinafter referred to as differential pressure) increases, the automatic strainer F1 becomes clogged. When the pressure difference between the pressure of PG4 and the pressure gauge PG2 increases, the filter F3 is clogged. When the clogging state of the filter media of the filters F2 and F3 is measured, the filter media is replaced.
[0041]
The filter material of the filter F2 is replaced by closing the valves V4 and V5, and the filter material of the filter F3 is replaced by closing the valves V5 and V6. The drain of the filter F2 is discharged by opening the valve V7, and the drain of the filter F3 is discharged by opening the valve V8.
