As a conventional reprocessing apparatus for emulsified waste oil, there is an apparatus that performs oil-water separation over an extended period of time or performs an electrochemical separation process.
The above-mentioned conventional apparatus has a problem that the ability to separate water in an emulsified state is limited, and it takes time and cost, and the present inventor is in a vacuum-reduced state in order to solve this problem. Vacuum depressurization apparatus having a vacuum depressurization chamber kept in a vacuum, and having a waste oil supply device for spraying or thinning emulsified waste oil into a dispersion device in the vacuum depressurization chamber, and having a storage tank for storing emulsified waste oil at the bottom A means for supplying emulsified waste oil in a pumped state to the vacuum decompression device, a steam duct for taking out water vapor evaporated in the vacuum decompression chamber, and communicating with the vacuum decompression chamber through the steam duct.

(Refer to Utility Model Registration No. 3148578)
しかしながら、上記真空式処理装置は、真空減圧室内で蒸発した水蒸気を蒸気ダクトに導いて、冷却液化するように構成されているので、真空減圧室内から水蒸気を完全に排除することが困難で、高純度の再生油にすることができないだけでなく、真空減圧室の外に蒸気ダクトや液化装置を装備するため装置が大型になる等の問題点があった。 However, the above-described vacuum processing apparatus is configured to guide the water vapor evaporated in the vacuum decompression chamber to the steam duct and liquefy it, so that it is difficult to completely remove the water vapor from the vacuum decompression chamber. In addition to being unable to make a regenerated oil of purity, there are problems such as the equipment becoming larger because a steam duct and a liquefaction device are provided outside the vacuum decompression chamber.
本発明が解決しようとする課題は、上記従来の処理装置の問題点を解決し、ほとんどの混入水分を除去して高純度の再生油を得ることができ、コンパクトで場所を取らない乳化廃油の再生処理装置および方法を提供することにある。 The problem to be solved by the present invention is to solve the above-mentioned problems of the conventional processing apparatus, remove most of the mixed water, and obtain a high-purity reclaimed oil. It is to provide a reproduction processing apparatus and method.

The emulsified waste oil regeneration treatment apparatus and method of the present invention have the following effects.
1) Since the emulsified waste oil is allowed to flow in a thin film on the surface of the dispersion plate in the decompression chamber set to a predetermined temperature and pressure, the water content in the waste oil is separated and evaporated. Moreover, it can be generated efficiently.
2) Since the waste oil containing moisture is returned to the waste oil feeder before being discharged to the reclaimed oil tank, the regenerated oil having a high purity can be recovered.
3) Since the condenser is provided in the decompression chamber, water vapor can be condensed reliably and efficiently.

上記圧力容器１は横向き円筒状であって、その内部は、上記真空ポンプ２により約６００〜７００ｍｍＨｇに減圧された減圧室Ａとなっている。該減圧室Ａの上部には、上記廃油供給器３が配設されている。本実施例において、該廃油供給器３は、軸方向にスリットが開設された管体であって、図１の紙面に対して垂直方向に配向されている。上記スリットからは、乳化廃油が薄膜状態で真下に流出するようになっている。該廃油供給器３と上記乳化廃油槽８の間には、供給パイプ３ａが配管されている。３ｂは供給ポンプである。 The pressure vessel 1 has a horizontal cylindrical shape, and the inside thereof is a decompression chamber A decompressed to about 600 to 700 mmHg by the vacuum pump 2. Above the decompression chamber A, the waste oil feeder 3 is disposed. In this embodiment, the waste oil feeder 3 is a tubular body having slits in the axial direction, and is oriented in a direction perpendicular to the paper surface of FIG. From the slit, the emulsified waste oil flows out directly below in a thin film state. A supply pipe 3 a is provided between the waste oil feeder 3 and the emulsified waste oil tank 8. 3b is a supply pump.
上記廃油供給器３の下方には、上記分散板４が傾斜状態で配設されている。該分散板４の上面には、メッシュ４ａが付設されていて、上記薄膜状態で供給された乳化廃油をゆっくりと流下せしめるようになっている。 Below the waste oil feeder 3, the dispersion plate 4 is disposed in an inclined state. A mesh 4a is attached to the upper surface of the dispersion plate 4, so that the emulsified waste oil supplied in the thin film state can flow slowly.
上記分散板４の下面に沿って、上記加熱器５が配設されている。該加熱器５の下端部には、加熱流体の供給パイプ５ａが、上端部には排出パイプ５ｂがそれぞれ接続されている。これら供給パイプ５ａおよび排出パイプ５ｂの他端側は加熱器１１に接続されていて、上記加熱器５内に、例えば５０〜５５℃に加熱された加熱油を供給するようになっている。なお、上記排出パイプ５ｂからは４５〜５０℃に減温された加熱油が出てくる。 The heater 5 is disposed along the lower surface of the dispersion plate 4. A heating fluid supply pipe 5 a is connected to the lower end of the heater 5, and a discharge pipe 5 b is connected to the upper end. The other end sides of the supply pipe 5a and the discharge pipe 5b are connected to the heater 11, and the heating oil heated to, for example, 50 to 55 ° C. is supplied into the heater 5. In addition, the heating oil reduced in temperature to 45-50 degreeC comes out from the said discharge pipe 5b.
上記凝縮器６は多数本の凝縮管６ａおよびこれら凝縮管６ａの下側に設けられた集水板６ｂから構成されている。各凝縮管６ａの一端側には供給パイプ６ｃが、他端側には排出パイプ６ｄがそれぞれ接続されている。これら供給パイプ６ｃおよび排出パイプ６ｄの他端側は冷却器６ｆに接続されていて、上記凝縮管６ａ内に、例えば水道水（常温）等の冷却水を供給するようになっている。上記集水板６ｂには集水パイプ６ｅが接続されており、該集水パイプ６ｅの先端部は上記排水槽１０上に臨んでいる。なお、上記凝縮管６ａには多数枚のフィンを等間隔に取り付けて、表面積を多くし、凝縮効率を向上せしめてもよい。６ｇはバルブであって、排水時を除いて、装置の作動中は原則として上記集水パイプ６ｅを閉じ、上記減圧室Ａ内を大気から遮断する。 The condenser 6 includes a large number of condensing pipes 6a and a water collecting plate 6b provided below the condensing pipes 6a. A supply pipe 6c is connected to one end side of each condensing pipe 6a, and a discharge pipe 6d is connected to the other end side. The other ends of the supply pipe 6c and the discharge pipe 6d are connected to a cooler 6f so that cooling water such as tap water (normal temperature) is supplied into the condensation pipe 6a. A water collection pipe 6 e is connected to the water collection plate 6 b, and the tip of the water collection pipe 6 e faces the drain tank 10. Note that a large number of fins may be attached to the condensing pipe 6a at equal intervals to increase the surface area and improve the condensing efficiency. Reference numeral 6g denotes a valve which, as a rule, closes the water collecting pipe 6e and shuts the decompression chamber A from the atmosphere during operation of the apparatus except during drainage.
上記液面調整堰７は上記圧力容器１の底部に設置されている。該圧力容器１は横向き円筒状の形状となっており、その底部は上向きに湾曲しているので、上記液面調整堰７の両側には、回収槽７ａと貯留槽７ｂが形成される。該回収槽７ａには回収パイプ９ａが接続されており、該回収パイプ９ａの先端部は上記再生油槽９に臨んでいる。９ｂは開閉弁、および９ｃはフィルターである。 The liquid level adjusting weir 7 is installed at the bottom of the pressure vessel 1. Since the pressure vessel 1 has a horizontal cylindrical shape and its bottom portion is curved upward, a recovery tank 7 a and a storage tank 7 b are formed on both sides of the liquid level adjusting weir 7. A recovery pipe 9a is connected to the recovery tank 7a, and a front end portion of the recovery pipe 9a faces the reclaimed oil tank 9. 9b is an on-off valve, and 9c is a filter.
上記貯留槽７ｂには排出パイプ７ｃが接続されており、該排出パイプ７ｃの他端部は、上記供給パイプ３ａの途中に設けられた切換弁３ｃに接続されている。該切換弁３ｃは、上記乳化廃油槽８と上記廃油供給器３を連通させて、該乳化廃油槽８内の乳化廃油を上記廃油供給器３に供給する場合と、上記貯留槽７ｂと上記廃油供給器３を連通させて、上記貯留槽７ｂ内の液体を上記廃油供給器３に送る場合と、に切り換えるようになっている。７ｄは流量調整弁である。 A discharge pipe 7c is connected to the storage tank 7b, and the other end of the discharge pipe 7c is connected to a switching valve 3c provided in the middle of the supply pipe 3a. The switching valve 3c allows the emulsified waste oil tank 8 and the waste oil supply device 3 to communicate with each other to supply the emulsified waste oil in the emulsified waste oil tank 8 to the waste oil supply device 3, and the storage tank 7b and the waste oil. The supply device 3 is communicated to switch the liquid in the storage tank 7b to the waste oil supply device 3. 7d is a flow regulating valve.
上記実施例の乳化廃油の再生処理装置は、以上のように構成されているので、上記乳化廃油槽８内に貯留されている乳化廃油（廃油と水とその他のスラッジ等の固形分のエマルジョン）は、上記供給パイプ３ａを通って上記供給ポンプ３ｂにより上記廃油供給器３に圧送される。 The emulsified waste oil regeneration treatment apparatus of the above embodiment is configured as described above, so that the emulsified waste oil stored in the emulsified waste oil tank 8 (emulsion of solids such as waste oil, water, and other sludge). Is pumped to the waste oil supplier 3 by the supply pump 3b through the supply pipe 3a.
上記廃油供給器３にはスリットが形成されているので、圧送された乳化廃油は、上記スリットから上記分散板４上に薄膜状に排出される。上記圧力容器１内は、上記真空ポンプ２により減圧されていると共に、上記加熱器５により高温になっているので、薄膜状に排出された乳化廃油は、降下中に水分の一部が蒸発して減圧室Ａ内に水蒸気となって漂う。 Since the slit is formed in the waste oil supply device 3, the emulsified waste oil that has been pumped is discharged from the slit onto the dispersion plate 4 in a thin film shape. Since the inside of the pressure vessel 1 is depressurized by the vacuum pump 2 and is heated to a high temperature by the heater 5, the emulsified waste oil discharged in the form of a thin film partially evaporates during the descent. And drifts into the decompression chamber A as water vapor.
上記分散板４上に薄膜状に排出され、降下途中に一部の水分が蒸発した乳化廃油は、斜めの分散板４上を薄膜状態で流下する。該分散板４は上記加熱器５により加熱されているので、上記乳化廃油は流下しながら加熱され、水分は更にその蒸発が促進される。水分が無くなるか若しくは少なくなった蒸発しない油分は、上記分散板４の下端部から上記回収槽７ａに滴下して回収される。なお、上記分散板４上のメッシュ４ａの抵抗により、薄膜状態で流下する乳化廃油は、ゆっくり時間をかけて流下するので、乳化廃油中の水分は油分を伴づれすることなく水蒸気となって、減圧室Ａ内に蒸発することができる。 The emulsified waste oil that has been discharged onto the dispersion plate 4 in a thin film form and part of the water evaporated during the descent flows down on the oblique dispersion plate 4 in a thin film state. Since the dispersion plate 4 is heated by the heater 5, the emulsified waste oil is heated while flowing down, and the moisture is further promoted to evaporate. The oil that does not evaporate when the moisture is lost or decreased is dropped and collected from the lower end of the dispersion plate 4 to the collection tank 7a. The emulsified waste oil that flows down in a thin film state flows slowly over time due to the resistance of the mesh 4a on the dispersion plate 4, so that the water in the emulsified waste oil becomes water vapor without accompanying oil, It can evaporate in the decompression chamber A.
上記分散板４の上方または面上で乳化廃油から蒸発して減圧室Ａ内を漂う水蒸気は、該減圧室Ａ内の上記凝縮器６により凝縮されて液体の水となる。すなわち、上記凝縮器６の上記凝縮管６ａ内には上記冷却器６ｆから冷却流体が供給されるので、該凝縮管６ａは冷却されており、その外表面に接触または近づいた水蒸気は、該凝縮管６ａに水滴となって付着し、成長した水滴は、上記集水板６ｂ上に滴下する。該集水板６ｂに集水された水は、上記集水パイプ６ｅを通って上記排水槽１０に排水される。 The water vapor evaporating from the emulsified waste oil above or on the surface of the dispersion plate 4 and drifting in the decompression chamber A is condensed by the condenser 6 in the decompression chamber A to become liquid water. That is, since the cooling fluid is supplied from the cooler 6f into the condenser pipe 6a of the condenser 6, the condenser pipe 6a is cooled, and the water vapor that comes into contact with or approaches the outer surface of the condenser pipe 6a The water droplets that adhere to the tube 6a as water droplets and grow are dripped onto the water collecting plate 6b. The water collected on the water collecting plate 6b is drained into the drainage tank 10 through the water collecting pipe 6e.
上記回収槽７ａに回収された廃油に依然として水分が混入している場合には、上記開閉弁９ｂを閉じて、回収槽７ａ内の廃油を上記液面調整堰７から上記貯留槽７ｂに越流させる。該貯留槽７ｂ内に貯留されている廃油は、上記切換弁３ｃを操作することにより、上記供給パイプ３ａを通って上記廃油供給器３に返送する。この時、上記乳化廃油槽８内の乳化廃油は供給されない。 When water is still mixed in the waste oil collected in the recovery tank 7a, the on-off valve 9b is closed, and the waste oil in the recovery tank 7a flows from the liquid level adjusting weir 7 to the storage tank 7b. Let The waste oil stored in the storage tank 7b is returned to the waste oil feeder 3 through the supply pipe 3a by operating the switching valve 3c. At this time, the emulsified waste oil in the emulsified waste oil tank 8 is not supplied.
上記廃油供給器３に返送された廃油は、再び上述の水分蒸発処理を受け、上記回収槽７ａに回収された廃油内の水分濃度が少なくなるまで、繰り返される。回収された廃油内の水分濃度が十分に少なくなると、上記開閉弁９ｂを開き、上記回収槽７ａ内の廃油を上記回収パイプ９ａを通って、上記再生油槽９に排出する。回収された廃油は、従来公知の分離技術によりスラッジ等の固形分を取り除かれ、再生油となる。 The waste oil returned to the waste oil supply device 3 is subjected to the above-described water evaporation process again, and is repeated until the water concentration in the waste oil recovered in the recovery tank 7a decreases. When the water concentration in the recovered waste oil becomes sufficiently low, the on-off valve 9b is opened, and the waste oil in the recovery tank 7a is discharged to the regenerated oil tank 9 through the recovery pipe 9a. From the recovered waste oil, solid content such as sludge is removed by a conventionally known separation technique to become regenerated oil.
上記回収槽７ａおよび上記貯留槽７ｂ内の廃油がほぼ無くなると、上記切換弁３ｃを閉じるとともに、上記切換弁３ｃを切り換えて上記乳化廃油槽８内の乳化廃油を上記廃油供給器３に供給する。 When there is almost no waste oil in the recovery tank 7a and the storage tank 7b, the switching valve 3c is closed and the switching valve 3c is switched to supply the emulsified waste oil in the emulsified waste oil tank 8 to the waste oil feeder 3. .
上記実施例において、上記廃油供給器３は、スリットを開けた管体に限定するものではなく、要するに、乳化廃油を薄膜状に排出できる構造のものであればよい。また、上記分散板４上に距離を隔てて配置することなく、該分散板４の上部表面に乳化廃油を薄膜状に直接排出する構造であってもよい。 In the said Example, the said waste oil supply device 3 is not limited to the pipe body which opened the slit, In short, what is necessary is just a structure which can discharge | emit emulsification waste oil in a thin film form. Further, the emulsified waste oil may be directly discharged in a thin film form on the upper surface of the dispersion plate 4 without being arranged on the dispersion plate 4 at a distance.
上記凝縮器６は、上記減圧室Ａ内に漂う水蒸気を効率よく凝縮回収できる構造であれば、上記構造に限定するものではなく、要するに、冷却された表面積を大きくでき、凝縮された水が速やかに滴下あるいは流下することのできる構造であればよい。 The condenser 6 is not limited to the above structure as long as it can efficiently condense and recover the water vapor drifting in the decompression chamber A. In short, the cooled surface area can be increased, and the condensed water can be quickly discharged. Any structure can be used as long as it can drop or flow down.
上記実施例では、乳化廃油の供給回路３ａを、貯留槽７ｂからの返送回路の一部に利用しているが、返送回路を別回路として、返送廃油を上記廃油供給器３に送るように構成してもよい。 In the above embodiment, the emulsified waste oil supply circuit 3a is used as a part of the return circuit from the storage tank 7b, but the return circuit is provided as a separate circuit so that the return waste oil is sent to the waste oil feeder 3. May be.
図２は、本発明装置の第２の実施例の説明図であって、図１に示す上記第１の実施例に対して下記の点で異なる。すなわち、上記第１の実施例では、廃油供給器３に圧送される乳化廃油は加熱処理されないで分散板４上に排出されるようになっているが、本第２の実施例では、上記廃油供給器３に連絡する供給パイプ３ａの途中に加熱手段３ｄを設ける。該加熱手段３ｄとしては、例えば、前記供給パイプ３ａの周囲に電気ヒーターや温水ジャケットを設ける手段があるが、要するに、乳化廃油を加熱する手段であれば、従来公知のいずれの加熱手段であってもよい。なお、この加熱手段３ｄは排出パイプ７ｃや貯留槽７ｂ内にも設けてもよい。上記加熱手段３ｄの配置は、上記複数個所、あるいは、選択されたいずれかの個所のいずれでもよい。上記加熱手段３ｄを設けることによって、加熱器５による廃油加熱を補助し、加熱器５を簡素に構成することができる。さらに、加熱手段３ｄを設けた場合、過熱器５を省略することもできる。 FIG. 2 is an explanatory diagram of a second embodiment of the apparatus of the present invention, and differs from the first embodiment shown in FIG. 1 in the following points. That is, in the first embodiment, the emulsified waste oil pressure-fed to the waste oil feeder 3 is discharged onto the dispersion plate 4 without being subjected to heat treatment. In the second embodiment, the waste oil is discharged. A heating means 3d is provided in the middle of the supply pipe 3a communicating with the supply device 3. As the heating means 3d, for example, there is a means for providing an electric heater or a hot water jacket around the supply pipe 3a. In short, any conventional heating means can be used as long as it is a means for heating the emulsified waste oil. Also good. The heating means 3d may also be provided in the discharge pipe 7c and the storage tank 7b. The arrangement of the heating means 3d may be any of the above-mentioned plurality of locations or any selected location. By providing the heating means 3d, the heating of the waste oil by the heater 5 can be assisted and the heater 5 can be simply configured. Furthermore, when the heating means 3d is provided, the superheater 5 can be omitted.
また、上記第１の実施例では圧力容器１を円筒状（断面が円形）に構成したが、図２に示すように、断面が縦長の楕円形あるいは小判状に形成してもよい。この場合、廃油供給器３や分散板４の上部に凝縮器６を配置して、その間に金網やパンチングメタルなどの油分捕捉用通気板１１を設置することができる。この油分捕捉用通気板１１は、分散板４から上昇する水蒸気の中に僅かに含まれる油分を付着せしめて捕捉する。その結果、この油分捕捉用通気板１１を通過する水蒸気は水分純度が高くなり、凝縮器６によって高純度の水が復水されることになる。なお、上記油分捕捉用通気板１１に捕捉された油分は、滴下や回収パイプなどの適宜回収手段（図示せず）によって上記回収槽７ａに回収される。 In the first embodiment, the pressure vessel 1 is formed in a cylindrical shape (circular in cross section). However, as shown in FIG. 2, the cross section may be formed in a vertically long oval or oval shape. In this case, the condenser 6 can be disposed above the waste oil supply device 3 and the dispersion plate 4, and an oil capturing trapping plate 11 such as a wire mesh or punching metal can be installed therebetween. The oil-capturing vent plate 11 captures an oil component that is slightly contained in water vapor rising from the dispersion plate 4. As a result, the water vapor passing through the oil-capturing ventilation plate 11 has a high water purity, and the high-purity water is condensed by the condenser 6. The oil captured by the oil capturing vent plate 11 is recovered in the recovery tank 7a by appropriate recovery means (not shown) such as dripping or a recovery pipe.
さらに、上記第１の実施例における排水槽１０内に、図２に示すように、堰板１０ａを設けて、排水槽１０の水面に浮く軽い油分を出来るだけ取り除いて、油分の出来るだけ少ない水を排水し、環境に配慮することができる。 Further, as shown in FIG. 2, a weir plate 10 a is provided in the drain tank 10 in the first embodiment to remove light oil floating on the water surface of the drain tank 10 as much as possible, and water with as little oil as possible. Can be drained and environmentally friendly.
本願発明、特に、第２の実施例の発明により、再処理された再生油槽９内の油分中の水分濃度が約２７０ｐｐｍ程度になるまで除去され、元の潤滑油等の基準値３００ｐｐｍ以下に純化されることが確認された。 According to the present invention, in particular, according to the invention of the second embodiment, the water content in the reprocessed oil tank 9 is removed until the water concentration is about 270 ppm, and purified to a reference value of 300 ppm or less of the original lubricating oil, etc. It was confirmed that
