以下、この発明につき図面を参照しつつ詳細に説明する。なお、この実施例によりこの発明が限定されるものではない。また、下記実施例における構成要素には、当業者が容易に想定できるもの、あるいは実質的に同一のものが含まれる。   Hereinafter, the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.

本発明による実施例に係る脱水処理装置について、図面を参照して説明する。図１は、実施例１に係る脱水処理装置の概略図である。
図１に示すように、水分含有油の脱水処理装置（以下「脱水装置」という）１０Ａは、水分含有油１１を導入した後静置し、油１１Ａと水１１Ｂとに分離する油水分離装置１２と、該油水分離装置１２で分離した油１１Ａ部分を別途投入して脱水処理する脱水装置１３と、該脱水装置１３に投入された油１１Ａ内に気泡１４を発生する気泡発生手段１５とを具備するものである。 A dehydrating apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a dehydration apparatus according to the first embodiment.
As shown in FIG. 1, a water-containing oil dehydrating apparatus (hereinafter referred to as “dehydrating apparatus”) 10 </ b> A is allowed to stand after introducing the water-containing oil 11 and is separated into oil 11 </ b> A and water 11 </ b> B. And a dehydrating device 13 for separately dehydrating the oil 11A portion separated by the oil / water separating device 12, and a bubble generating means 15 for generating bubbles 14 in the oil 11A charged in the dehydrating device 13. To do.

また、本実施例では、脱水装置１３の内部を加温する加温手段１６を設け、油１１Ａを加温するようにしている。
図１中、符号１３ａは蓋、１３ｂは本体、１８は乾燥気体、１９は脱水処理油、Ｌ1は水含有油導入ライン、Ｌ2は分離油供給ライン、Ｌ3は乾燥気体供給ライン、Ｌ4は排気ライン、Ｖ1〜Ｖ2は開閉バルブ、Ｐは乾燥気体供給ポンプを各々図示する。 Further, in this embodiment, a heating means 16 for heating the inside of the dehydrator 13 is provided to heat the oil 11A.
In FIG. 1, reference numeral 13 a is a lid, 13 b is a main body, 18 is a dry gas, 19 is a dehydrated oil, L 1 is a water-containing oil introduction line, L 2 is a separated oil supply line, L 3 is a dry gas supply line, L 4 exhaust line, V 1 ~V 2 opening and closing valve, P is respectively shown a dry gas supply pump.

そして、油水分離装置１２に水含有油１１を水含有油導入ラインＬ1により導入し、所定時間静置させることで、油１１Ａと水１１Ｂとにその比重差により分離するようにしている。 Then, water containing oil 11 in the oil-water separator 12 is introduced by the water-containing oil introduction line L 1, that is standing a predetermined time, so that the separation by specific gravity difference into an oil 11A and water 11B.

所定時間静置後、分離した油１１Ａのみを、分離油供給ラインＬ2を介して脱水装置１３に供給するようにしている。
静置する時間は、少なくとも５時間以上静置することが好ましい。これは、水分含有油１１が懸濁状態の場合、少なくとも５時間以上静置することで、分離水がわかれるからである。なお、静置時間は長いほど好ましい。 Predetermined time standing, only separated oil 11A, and then supplied to the dewatering device 13 via a separate oil supply line L 2.
The time for standing is preferably set to stand for at least 5 hours. This is because, when the water-containing oil 11 is in a suspended state, the separated water can be detected by standing for at least 5 hours. The longer the standing time, the better.

油１１Ａと水１１Ｂとの分離は、比重差により分離しており、バルブＶ1、Ｖ2のいずれかを操作して、下層部分から外部に抜き出している。 The oil 11A and the water 11B are separated by a difference in specific gravity, and one of the valves V 1 and V 2 is operated to draw out from the lower layer portion.

なお、油１１Ａと水１１Ｂとの分離のバルブの切替えには、配管の内部が確認できるような例えばカラーセンサ、紫外線センサ等を用いて、油１１Ａと水１１Ｂとを判別して、バルブＶ1、Ｖ2の切替え操作の自動化を図るようにしてもよい。 In order to switch the valve for separating the oil 11A and the water 11B, for example, using a color sensor, an ultraviolet sensor or the like that can confirm the inside of the pipe, the oil 11A and the water 11B are discriminated, and the valve V 1 is used. , V 2 switching operation may be automated.

これにより、脱水装置１３には油１１Ａのみが分離油供給ラインＬ2を介して供給されることとなり、脱水装置１３においては、分離水の除去が不要となる。
この結果、多量に水分が存在する場合の大部分の分離水をこの油水分離装置１２の静置処理により分離することができる。
すなわち、油水分離装置１２を設けない場合には、水分を含む油に単に気泡を長時間に亙って発生させ、水分を脱気するような場合では、長時間の時間を要する。
これに対し、本発明のように、油水分離装置１２を設け、分離水である水１１Ｂを予め除去し、油１１Ａ部分のみを分離し、油中にのみ溶解する水（溶解水分）を除去することで、脱水時間の短縮が可能となる。
本発明における水分の含有量は限定されるものではないが、数％から数１０％程度の水を含有する場合においても、本発明の脱水装置で迅速に処理することができる。 As a result, only the oil 11A is supplied to the dehydrating device 13 via the separated oil supply line L 2 , and the dewatering device 13 does not need to remove the separated water.
As a result, most of the separated water when a large amount of water is present can be separated by the stationary treatment of the oil / water separator 12.
That is, when the oil / water separator 12 is not provided, it takes a long time in the case where bubbles are simply generated over a long period of time in the oil containing water and the water is deaerated.
On the other hand, as in the present invention, the oil / water separator 12 is provided, the water 11B as the separated water is removed in advance, only the oil 11A portion is separated, and the water (dissolved water) dissolved only in the oil is removed. This makes it possible to shorten the dehydration time.
The water content in the present invention is not limited, but even when it contains several% to several tens% of water, it can be quickly treated with the dehydrating apparatus of the present invention.

ここで、本実施例では、油水分離装置１２の周囲を冷却する冷却手段２１が設けられている。
これは、油の温度が低い場合には、油１１Ａ側への水分の溶解量が小さくなるからである。 Here, in this embodiment, a cooling means 21 for cooling the periphery of the oil / water separator 12 is provided.
This is because when the temperature of the oil is low, the amount of water dissolved on the oil 11A side becomes small.

図４は脱水装置１３での脱水処理時間と油中の水分量との関係を示す図である。
図４では、試験例として脱水装置を加温し、そこに窒素ガスを導入した。
比較例１は脱水装置を加温したのみである。比較例２は窒素ガスを導入したのみである。
図４に示すように、脱水装置を加温しつつ窒素ガスを導入して脱水処理することで、水分除去率が大幅に向上するのが確認された。 FIG. 4 is a diagram showing the relationship between the dehydration time in the dehydrator 13 and the amount of water in the oil.
In FIG. 4, a dehydrator was heated as a test example, and nitrogen gas was introduced therein.
In Comparative Example 1, only the dehydrator was heated. In Comparative Example 2, only nitrogen gas was introduced.
As shown in FIG. 4, it was confirmed that the moisture removal rate was greatly improved by introducing nitrogen gas while heating the dehydrator and performing dehydration.

また、例えば、油と水とを５：１の割合（容量）で混合し、所定時間（１２時間）静置後、油を分離し、油中の水分をカールフィッシャー法測定器により計測した一例を、「表１」に示す。   Further, for example, an example in which oil and water are mixed at a ratio (volume) of 5: 1, allowed to stand for a predetermined time (12 hours), oil is separated, and moisture in the oil is measured by a Karl Fischer method measuring instrument. Is shown in Table 1.

下記「表１」に示すように、２８℃の場合では、溶解水分量が０．３６％であったものが、冷却手段で冷却して５℃の場合では、溶解水分量が０．２３％と、０．１３％も少ないことが判明した。   As shown in “Table 1” below, the dissolved water content was 0.36% at 28 ° C., but the dissolved water content was 0.23% when cooled at 5 ° C. by the cooling means. It was found to be as little as 0.13%.

Figure 0005409593
Figure 0005409593

よって、水含有油１１を油水分離装置１２に投入後、冷却手段２１により冷却することで、溶解水分量を１／３程度減らすことが可能となる。   Therefore, after the water-containing oil 11 is charged into the oil / water separator 12 and cooled by the cooling means 21, the amount of dissolved water can be reduced by about 1/3.

よって、静置する間に冷却手段２１で冷却することで、油中に溶解する水（溶解水分）を低減させることができ、脱水装置１３での溶解水分量を減らすようにしている。   Therefore, the water (dissolved water) dissolved in the oil can be reduced by cooling with the cooling means 21 while standing, and the amount of dissolved water in the dehydrator 13 is reduced.

本発明で処理する油の一例としては、燃料油、作動油、潤滑油等を挙げることができるが、水分が混入しやすい油であればいずれをも対象とすることができる。   Examples of the oil to be treated in the present invention include fuel oil, hydraulic oil, lubricating oil, and the like, but any oil can be used as long as it is easily mixed with moisture.

また、脱水装置１３においては、加温手段１６で加温することが、脱水効率を向上するので好ましい。
なお、加温手段１６での好適な加温温度としては、例えば３０℃以上に加温すればよく、対象とする油の耐熱温度以下とすることが必要である。これは、水分を除去するための、油自体が劣化するのを防止するためである。 Moreover, in the dehydrating apparatus 13, it is preferable to heat by the heating means 16 because the dehydrating efficiency is improved.
In addition, as a suitable heating temperature in the heating means 16, what is necessary is just to heat to 30 degreeC or more, for example, and it is necessary to make it below the heat-resistant temperature of the target oil. This is to prevent deterioration of the oil itself for removing moisture.

ここで、加温手段１６としては、本実施例のようにヒータを用いても良いが、冷却手段２１で用いる冷却装置から発生する廃熱を加温の熱源に用いるようにしてもよい。   Here, as the heating means 16, a heater may be used as in the present embodiment, but waste heat generated from the cooling device used in the cooling means 21 may be used as a heating heat source.

また、気泡発生手段１５に供給する気体として、空気を用いる場合には、供給する空気に含まれる水分を除湿する除湿手段を有するようにしてもよい。   Further, when air is used as the gas supplied to the bubble generating means 15, a dehumidifying means for dehumidifying moisture contained in the supplied air may be provided.

本発明による実施例に係る脱水処理装置について、図面を参照して説明する。図２は、実施例２に係る脱水処理装置の概略図である。なお、実施例１の脱水処理装置の構成部材と同一の部材については、同一符号を付してその説明は省略する。
図２に示すように、実施例２に係る脱水処理装置１０Ｂは、実施例１に係る脱水処理装置１０Ａにおいて、さらに脱水装置１３の気泡発生手段１５で発生させた気体を再循環する気体循環手段を有している。 A dehydrating apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a schematic diagram of a dehydration apparatus according to the second embodiment. In addition, about the member same as the structural member of the dehydration processing apparatus of Example 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
As shown in FIG. 2, the dehydrating apparatus 10B according to the second embodiment is a gas circulating means for recirculating the gas generated by the bubble generating means 15 of the dehydrating apparatus 13 in the dehydrating apparatus 10A according to the first embodiment. have.

本実施例の気体循環手段は、蓋１３ａから発生した気泡１４を集めて循環させる気体循環ラインＬ5と、循環気体１８ａに同伴される水分及び油を分離処理する気体処理装置３１と、気体処理装置３１の前後に設けられ、循環気体１８ａ中の水分及び油分を計測するガス測定手段３２Ａ、３２Ｂとを具備するものである。
図２中、Ｖ11〜Ｖ13は開閉バルブを図示する。 The gas circulation means of the present embodiment includes a gas circulation line L 5 that collects and circulates the bubbles 14 generated from the lid 13a, a gas treatment device 31 that separates moisture and oil accompanying the circulation gas 18a, and a gas treatment. Gas measuring means 32A and 32B are provided before and after the device 31 and measure moisture and oil content in the circulating gas 18a.
In FIG. 2, V 11 to V 13 indicate open / close valves.

気体処理装置３１は、循環気体１８ａを冷却して、脱水処理で同伴される水分及び油分を回収するものである。
図３は、気体処理装置の一例を示す図である。
図３に示すように、循環気体１８ａを導入する気体処理装置本体３１ａと、導入された循環気体１８ａを冷却する冷却手段２１と、気体処理装置本体３１ａの下側に設けられ、ガスから分離された水分及び油分を静置分離する分離装置３３とを具備するものである。図３中、符号Ｖ21〜Ｖ22は開閉バルブを各々図示する。
分離装置３３で分離された油１１Ａは、分離油供給ラインＬ2に供給して脱水装置１３に戻し、再度脱水処理を行い、乾燥気体１８ｂとするようにしている。 The gas processing device 31 cools the circulating gas 18a and recovers moisture and oil components accompanying the dehydration process.
FIG. 3 is a diagram illustrating an example of a gas processing apparatus.
As shown in FIG. 3, the gas processing device main body 31a for introducing the circulating gas 18a, the cooling means 21 for cooling the introduced circulating gas 18a, and the lower side of the gas processing device main body 31a are separated from the gas. And a separation device 33 for stationary separation of water and oil. In FIG. 3, reference numerals V 21 to V 22 denote open / close valves, respectively.
Oil 11A separated by the separator 33 is supplied to a separate oil supply line L 2 back to the dewatering device 13, so that performed again dehydrated, and dried gas 18b.

本実施例によれば、実施例１のように、脱水装置１３内に導入する乾燥気体１８を外部から連続して供給する必要がなくなる。   According to the present embodiment, unlike the first embodiment, it is not necessary to continuously supply the dry gas 18 introduced into the dehydrating apparatus 13 from the outside.

また、気体処理装置３１で冷却の際に発生する排熱は、実施例１と同様に脱水装置１３の加温手段１６に利用することができる。   Further, the exhaust heat generated at the time of cooling in the gas processing device 31 can be used for the heating means 16 of the dehydrating device 13 as in the first embodiment.

ガス測定手段３２Ａ、３２Ｂは、循環気体１８ａの性状を監視するものであり、気体処理装置３１での冷却能力の調整を行うようにしている。
すなわち、ガス測定手段３２Ａにおいて測定した結果、脱水装置１３から抜出した循環気体１８ａ中の水分含有量が高い場合には、気体処理装置３１での冷却手段２１の冷却効率を向上させて、より低温での水分分離を行うようにしている。 The gas measuring means 32A and 32B monitor the properties of the circulating gas 18a and adjust the cooling capacity in the gas processing device 31.
That is, when the moisture content in the circulating gas 18a extracted from the dehydrating device 13 is high as a result of measurement in the gas measuring means 32A, the cooling efficiency of the cooling means 21 in the gas processing device 31 is improved and the temperature is lowered. Water separation is performed at

また、ガス測定手段３２Ｂにおいて、処理後の乾燥気体１８ｂのガス性状を計測した結果、水分が規定値よりも高い場合には、バルブＶ11を閉じると共に、バルブＶ12を開けて、再度気体処理装置３１で処理を行うようにして、所定値以下の水分量の乾燥気体１８ｂとなるように再度脱水処理するようにしている。
なお、この再度脱水処理する場合においては、乾燥気体１８を乾燥気体供給ラインＬ3から脱水処置１３に導入して、脱水処理を継続するようにしている。 Further, the gas measuring means 32B, the results of the gas property of the dry gas 18b after processing were measured, if the moisture is higher than the specified value, it closes the valve V 11, by opening the valve V 12, again gassing The treatment is performed by the apparatus 31, and the dehydration process is performed again so that the dry gas 18b has a moisture amount equal to or less than a predetermined value.
Incidentally, in the case of the re-dehydration process, the dry gas 18 is introduced into the dehydration treatment 13 from the dry gas supply line L 3, and so as to continue the dewatering process.

本発明による実施例に係る脱水処理装置について、図面を参照して説明する。図５は、実施例３に係る脱水処理装置の概略図である。なお、実施例１の脱水処理装置の構成部材と同一の部材については、同一符号を付してその説明は省略する。
図５に示すように、実施例３に係る脱水処理装置１０Ｃは、実施例１に係る脱水処理装置１０Ａにおいて、さらに脱水装置１３の下端側から油１１Ａを抜出し、脱水装置１３の上方から再循環する油循環ラインＬ6を有している。
また、油循環ラインＬ6の導入側には、油をシャワー状に流すノズル４１が装着されている。 A dehydrating apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a schematic diagram of a dehydration apparatus according to the third embodiment. In addition, about the member same as the structural member of the dehydration processing apparatus of Example 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
As illustrated in FIG. 5, the dehydration apparatus 10 </ b> C according to the third embodiment further extracts oil 11 </ b> A from the lower end side of the dehydration apparatus 13 and recirculates from above the dehydration apparatus 13 in the dehydration apparatus 10 </ b> A according to the first embodiment. An oil circulation line L 6 is provided.
Further, a nozzle 41 for flowing oil in a shower shape is mounted on the introduction side of the oil circulation line L 6 .

このノズル４１を利用して脱水装置１３の上部から油１１Ａを導入することで、気泡発生手段１５から発生した気泡１４と対向接触するようにしている。この結果、気泡１４は、上方から導入される油１１Ａに押されながら上昇することとなるので、脱水装置１３内部での滞留時間が増加し、さらに脱水処理能力の向上を図ることができる。   The nozzle 11 is used to introduce the oil 11A from the upper part of the dehydrator 13 so that the air bubbles 14 generated from the air bubble generating means 15 are opposed to each other. As a result, the bubbles 14 rise while being pushed by the oil 11A introduced from above, so that the residence time inside the dehydrating apparatus 13 is increased and the dewatering capacity can be further improved.

以上のように、本発明に係る水分含有油の脱水処理装置及び方法によれば、水分を多量に含む油から溶解水を効率よく処理することができ、例えば燃料油、潤滑油の処理が簡易になる。   As described above, according to the apparatus and method for dehydrating water-containing oil according to the present invention, dissolved water can be efficiently processed from oil containing a large amount of water. For example, the processing of fuel oil and lubricating oil is simple. become.
