Description

本発明は、燃料油、水及び乳化剤等の添加剤の混合液を攪拌してエマルション燃料を製造するエマルション燃料製造装置に関する。   The present invention relates to an emulsion fuel production apparatus for producing an emulsion fuel by stirring a mixed liquid of additives such as fuel oil, water and an emulsifier.

２００８年７月７日から始まる洞爺湖サミット（主要国首脳会議）では、地球温暖化防止に向けた対策が主要議題として扱われる。
燃料油の価格高騰、環境悪化、地球温暖化等の諸問題に対応するため、燃料油中に水粒子が分散したエマルション燃料が実用化されている。エマルション燃料は、燃焼効率が高く、油消費量が少なくて済み、燃焼による窒素酸化物や粒子状物質の発生を抑制する効果がある。特に、近年では、水を多く加えて、油と水を１：１の比率で混合したエマルション燃料も開発されている。
このようなエマルション燃料は、油と水が分離するのを防ぐために、粒子径をできる限り微細化する必要がある。 At the Toyako Summit (major summit meeting) starting on July 7, 2008, measures to prevent global warming will be treated as the main agenda.
Emulsion fuels in which water particles are dispersed in fuel oil have been put into practical use in order to cope with various problems such as a rise in the price of fuel oil, environmental deterioration, and global warming. Emulsion fuel has high combustion efficiency, requires less oil consumption, and has an effect of suppressing generation of nitrogen oxides and particulate matter due to combustion. In particular, in recent years, an emulsion fuel in which a large amount of water is added and oil and water are mixed at a ratio of 1: 1 has been developed.
Such an emulsion fuel needs to be made as fine as possible in order to prevent the oil and water from separating.

従来、攪拌効率を高めて、短時間で燃料油と水を微細混合するエマルション燃料製造装置が種々提案されている。
例えば、特許文献１には、攪拌容器の上部周壁に、攪拌容器内の混液に第１の旋回流を形成する噴射ノズルを設置し、攪拌容器の底部に第２の旋回流を形成する攪拌翼を設けたエマルジョン燃料製造装置が記載されている。
しかし、この装置は、２種類の攪拌装置が必要なので攪拌容器が大型化し、構造も複雑であり、攪拌を行なうのにエネルギー消費量が増加するだけでなく、混液を噴射する噴射ノズルが目詰まりを起こしやすい。 Conventionally, various emulsion fuel production apparatuses that improve the stirring efficiency and finely mix fuel oil and water in a short time have been proposed.
For example, in Patent Document 1, an injection nozzle that forms a first swirling flow in a mixed liquid in a stirring vessel is installed on the upper peripheral wall of the stirring vessel, and a stirring blade that forms a second swirling flow at the bottom of the stirring vessel An emulsion fuel production apparatus is provided.
However, since this apparatus requires two types of stirring devices, the size of the stirring container is increased and the structure is complicated, and not only the energy consumption increases to perform stirring, but also the injection nozzle that injects the mixed liquid is clogged. It is easy to cause.

また、特許文献２には、複数枚の翼からなる回転翼状体と、ねじり方向を逆向きにした回転翼状体を交互に複数枚配置して、管内に挿入した列状集合体と、中央に穿孔された半球面状体と、周辺部に複数の微小孔を設けた半球面状体を複数個組み合わせて配置して、管内に挿入した列状集合体とを有し、エマルジョン流体が列状回転翼状体及び列状半球面状体を通過して微細混合されるエマルジョン製造装置が開示されている。
しかしながら、この装置はさらに構造が複雑であって、列状回転翼状体を回転させるのに多くの電力を消費し、半球面状体も目詰まりしやすいという欠点がある。 In Patent Document 2, a rotating wing-like body composed of a plurality of wings and a plurality of rotating wing-like bodies having opposite torsional directions are alternately arranged, and a row-like assembly inserted in the tube, A perforated hemispherical body and an array of rows of hemispherical bodies with a plurality of micro-holes in the periphery are combined and placed in the tube, and the emulsion fluid is in a line An emulsion production apparatus is disclosed that is finely mixed through a rotating wing and a row of hemispheres.
However, this apparatus is further complicated in structure, and consumes a lot of power to rotate the row-shaped rotary wings, and the hemispherical body is easily clogged.

本発明が解決しようとする課題は、攪拌効率が高く、しかも、構造が簡単で、製造コスト及び運転コストが低廉で済むエマルション燃料製造装置を提供することにある。   The problem to be solved by the present invention is to provide an emulsion fuel production apparatus which has high stirring efficiency, has a simple structure, and can be produced at low manufacturing and operating costs.

本発明は、燃料油、水及び乳化剤等の添加剤の混合液を周方向の旋回流により攪拌する攪拌槽を備えたエマルション燃料製造装置に関し、前記攪拌槽の内面から中心部に向けて、軸方向に沿う少なくとも１枚のフィンを張り出し、該フィンの中心部寄り側縁に矩形の突出部を少なくとも１つ形成してある。
複数のフィンを前記攪拌槽の内面に、その周方向に等間隔で配置するのが望ましい。
前記フィンにそれぞれ複数の突出部を形成し、前記突出部の軸方向の寸法を前記突出部間の距離よりも大きくすると良い。 The present invention relates to an emulsion fuel production apparatus provided with an agitation tank that stirs a mixed liquid of additives such as fuel oil, water and an emulsifier by a swirling flow in a circumferential direction. At least one fin extending in the direction is projected, and at least one rectangular protrusion is formed on the side edge closer to the center of the fin.
It is desirable to arrange a plurality of fins on the inner surface of the stirring tank at equal intervals in the circumferential direction.
A plurality of protrusions may be formed on each of the fins, and the axial dimension of the protrusions may be larger than the distance between the protrusions.

前記突出部の張り出し幅を前記フィンの本体部分の幅よりも大きくしても良い。
前記攪拌槽へ水を供給する経路に、水流と交差する磁場を形成する改質装置を設け、前記攪拌槽から延びる給油路を燃料備蓄槽に連結すると共に、前記給油路に攪拌パイプを設置し、前記燃料備蓄槽から延びる循環路を前記攪拌槽と攪拌パイプとの間において前記給油路に接続してあり、前記攪拌パイプの内面は、その一端から軸方向中間部に向けて段階的に径が狭くなり、軸方向中間部から他端に向けて段階的に径が広くなる多数の段を有するのが望ましい。
この場合、前記攪拌パイプの軸方向中間部には、内径が全長に亘って均一な円柱状流路を形成すると良い。 The projecting width of the protruding portion may be larger than the width of the main body portion of the fin.
A reformer that forms a magnetic field that intersects the water flow is provided in a path for supplying water to the agitation tank, an oil supply path extending from the agitation tank is connected to a fuel storage tank, and an agitation pipe is installed in the oil supply path. A circulation path extending from the fuel storage tank is connected to the oil supply path between the agitation tank and the agitation pipe, and the inner surface of the agitation pipe has a diameter stepwise from one end toward an intermediate portion in the axial direction. It is desirable to have a large number of steps that become narrower and gradually increase in diameter from the intermediate portion in the axial direction toward the other end.
In this case, it is preferable to form a cylindrical flow path having a uniform inner diameter over the entire length in the axially intermediate portion of the stirring pipe.

請求項１に係る発明によれば、旋回流がフィンにぶつかって乱流が発生し、しかも、突出部が形成されている部分と形成されていない部分とでは流速が異なると共に、軸方向への流れも発生するので、短時間で燃料油中に微細な粒子を分散できる。
また、突出部が矩形なので、角がなだらかなものに比べて抵抗が大きくなり、攪拌効率が高まる。
さらに、攪拌槽の内面にフィンを固定しただけなので、一般的なタンクを利用することができ、旋回流を発生する攪拌装置を増やしたり、特別な攪拌装置を設置する必要が無く、装置全体が小型化されて一般家庭や小型船舶等でも利用しやすく、運転に要するエネルギーも少なくて済む。 According to the first aspect of the present invention, the turbulent flow is generated by the swirling flow hitting the fins, and the flow velocity is different between the portion where the protrusion is formed and the portion where the protrusion is not formed. Since a flow is also generated, fine particles can be dispersed in the fuel oil in a short time.
Moreover, since a protrusion part is a rectangle, resistance becomes large compared with a thing with a gentle angle | corner, and stirring efficiency increases.
Furthermore, since the fins are only fixed to the inner surface of the stirring tank, a general tank can be used, and it is not necessary to increase the number of stirring devices that generate a swirl flow or install a special stirring device. Miniaturized and easy to use in ordinary homes and small ships, and requires less energy for operation.

請求項２に係る発明によれば、旋回流を複数のフィンにぶつけて多くの乱流を形成することができる。
請求項３に係る発明によれば、突出部間の隙間を狭くすることにより、この隙間を通過する流れを速め、攪拌槽内の流速の差を大きくして攪拌効率を高めることができる。
請求項４に係る発明によれば、突出部による抵抗を大きくして、旋回流が突出部にぶつかる際の衝撃を大きくし、水粒子の微細化を促進する。 According to the invention which concerns on Claim 2, many turbulent flows can be formed by colliding a swirl flow with several fins.
According to the invention which concerns on Claim 3, by narrowing the clearance gap between protrusion parts, the flow which passes this clearance gap can be accelerated | stimulated, the difference of the flow velocity in a stirring tank can be enlarged, and stirring efficiency can be improved.
According to the invention which concerns on Claim 4, the resistance by a protrusion part is enlarged, the impact at the time of a swirling flow colliding with a protrusion part is enlarged, and refinement | miniaturization of a water particle is accelerated | stimulated.

請求項５に係る発明によれば、攪拌槽から燃料備蓄槽へエマルション燃料を移動させる際、及び、燃料備蓄槽内のエマルション燃料を循環させる際に、攪拌パイプを通過させることにより、次第に径が狭くなる部分では流れに交差する段状の面にぶつかって拡販され、次第に径が広くなる部分では急激な径の変化によって攪拌され、この結果、燃料油と水との分離を防ぐことができる。
また、攪拌パイプは、その軸方向中間部で狭くなって両端部で広くなっているので、一端から他端に向かって次第に細くしたものよりも内径を小さくでき、このため、流れの中心部分をも確実に攪拌することが可能であり、エマルション燃料を一端から他端に向かって流しても、他端から一端に向かって流しても同様の攪拌効果が得られる。
さらに、エマルション燃料中の不純物が多数の段にぶつかって除去され、燃料備蓄槽内に侵入しにくい。
また、磁場を通過した水分子が帯電して活発に衝突するため、攪拌による微細化が促進される。
請求項６に係る発明によれば、攪拌パイプの軸方向中間部において、断面積の小さい円柱状流路により流速を上昇させて圧力を低下させ、段階的に断面積が増加する部分へ流れた時の流速及び圧力の変化を大きくし、攪拌効率を高める。 According to the invention of claim 5, when the emulsion fuel is moved from the agitation tank to the fuel storage tank and when the emulsion fuel in the fuel storage tank is circulated, the diameter is gradually increased by passing the agitation pipe. In the narrowed part, it hits a stepped surface that intersects the flow and expanded, and in the gradually widened part, it is stirred by a sudden change in diameter, and as a result, separation of fuel oil and water can be prevented.
In addition, since the stirring pipe is narrow at the middle in the axial direction and wide at both ends, the inner diameter can be made smaller than that gradually narrowed from one end to the other, so that the central portion of the flow can be reduced. However, even if the emulsion fuel is flowed from one end to the other end or from the other end to the one end, the same stirring effect can be obtained.
Furthermore, impurities in the emulsion fuel are removed by hitting a large number of stages, and do not easily enter the fuel storage tank.
Further, since water molecules that have passed through the magnetic field are charged and collide actively, miniaturization by stirring is promoted.
According to the invention of claim 6, in the middle part in the axial direction of the stirring pipe, the flow rate is increased by the cylindrical flow path having a small cross-sectional area to decrease the pressure, and the flow has flowed to the part where the cross-sectional area increases stepwise. Increase the flow rate and pressure change at the time to increase the stirring efficiency.

以下、本発明の実施例を図面に基づいて詳細に説明する。
図１に示すように、本発明のエマルション燃料製造装置は、攪拌槽１及び燃料備蓄槽２を備え、攪拌槽１から延びる給油路３を燃料備蓄槽２に連結すると共に、給油路３に攪拌パイプ４を設置し、燃料備蓄槽２から延びる循環路５を、攪拌槽１と攪拌パイプ４との間に設置された切換弁１３を介して給油路３に接続してある。
攪拌槽１には、重油、軽油等の燃料油と、水と、乳化剤等の添加剤とが供給され、水を供給する経路には水流と交差する磁場を形成する改質装置６を設置してある。なお、燃料油と水との比率は、９０％：１０％〜５０％：５０％とすることができる。
また、循環路５には切換弁１４を介して燃料排出路１５が接続され、燃料排出路１５の先端にボイラー等の燃焼装置８が連結される。燃料排出路１５には、必要に応じて加温装置を有するサービスタンク７を設置しても良い。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the emulsion fuel production apparatus of the present invention includes an agitation tank 1 and a fuel storage tank 2, connects an oil supply path 3 extending from the agitation tank 1 to the fuel storage tank 2, and agitates the oil supply path 3. A pipe 4 is installed, and a circulation path 5 extending from the fuel storage tank 2 is connected to the oil supply path 3 via a switching valve 13 installed between the stirring tank 1 and the stirring pipe 4.
Fuel oil such as heavy oil and light oil, water, and additives such as emulsifiers are supplied to the stirring tank 1, and a reformer 6 that forms a magnetic field that intersects the water flow is installed in the water supply path. It is. The ratio of fuel oil to water can be 90%: 10% to 50%: 50%.
In addition, a fuel discharge path 15 is connected to the circulation path 5 via a switching valve 14, and a combustion device 8 such as a boiler is connected to the tip of the fuel discharge path 15. A service tank 7 having a heating device may be installed in the fuel discharge path 15 as necessary.

攪拌槽１は、図２及び図３に示すように、所定容量の円筒体であり、その中心下部に回転翼９を設置してある。回転翼９は図示省略した電動モータにより回転させられる。そして、回転翼９が形成する周方向の旋回流により、攪拌槽１内に収容されている燃料油、水及び添加剤の混合液を攪拌して、油中に水粒子を分散させるようになっている。
また、攪拌槽１の内面から中心部に向かって、軸方向に沿う少なくとも１枚のフィン１０を張り出してある。本実施例では、フィン１０を周方向に等間隔で４枚配置してあるが、攪拌槽１の直径によってフィン１０の数は任意に変更できる。 As shown in FIGS. 2 and 3, the agitation tank 1 is a cylindrical body having a predetermined capacity, and a rotary blade 9 is installed at the center lower part thereof. The rotary blade 9 is rotated by an electric motor (not shown). Then, the mixture of fuel oil, water, and additive contained in the agitation tank 1 is agitated by the swirling flow in the circumferential direction formed by the rotor blades 9, and the water particles are dispersed in the oil. ing.
Further, at least one fin 10 extending in the axial direction is projected from the inner surface of the stirring tank 1 toward the center. In the present embodiment, four fins 10 are arranged at equal intervals in the circumferential direction, but the number of fins 10 can be arbitrarily changed depending on the diameter of the stirring tank 1.

図４に示すように、フィン１０の中心部寄り側縁には、矩形の突出部１２を少なくとも１つ形成してある。
フィン１０及び突出部１２の寸法と突出部１２の数は攪拌槽１の大きさによって適宜変更することができるが、突出部１２の張り出し幅ａをフィン１０の本体部分の幅ｂよりも大きくし、複数の突出部１２を形成する場合、突出部１２の軸方向の寸法ｃを突出部１２間の距離ｄよりも大きくするのが望ましい。 As shown in FIG. 4, at least one rectangular protrusion 12 is formed on the side edge closer to the center of the fin 10.
The dimensions of the fins 10 and the protrusions 12 and the number of the protrusions 12 can be appropriately changed according to the size of the stirring tank 1, but the protruding width a of the protrusion 12 is made larger than the width b of the main body portion of the fin 10. When forming the plurality of protrusions 12, it is desirable that the dimension c in the axial direction of the protrusions 12 be larger than the distance d between the protrusions 12.

例えば、攪拌槽１の直径が６００ｍｍ、高さが６００ｍｍであれば、攪拌槽１の底から長さＬが４８０ｍｍのフィン１０を起立させ、フィン１０の上端及びその下方に合計二つの突出部１２を形成する。また、突出部１２の張り出し幅ａを７０ｍｍ、フィン１０の本体部分の幅ｂを３０ｍｍとし、突出部１２の軸方向の寸法ｃを１４０ｍｍ、突出部１２間の距離ｄを５０ｍｍとする。
攪拌槽１の直径が６００ｍｍ、高さが１２００ｍｍの場合、フィン１０の長さＬを６７０ｍｍとし、フィン１０の上端及びその下方に合計三つの突出部１２をそれぞれ５０ｍｍの距離をあけて形成する。その他の寸法は、攪拌槽１の高さが６００ｍｍの場合と同じである。 For example, if the diameter of the stirring tank 1 is 600 mm and the height is 600 mm, the fin 10 having a length L of 480 mm is erected from the bottom of the stirring tank 1, and a total of two protrusions 12 are provided at the upper end of the fin 10 and below the fin 10. Form. Further, the protruding width a of the protruding portion 12 is 70 mm, the width b of the body portion of the fin 10 is 30 mm, the axial dimension c of the protruding portion 12 is 140 mm, and the distance d between the protruding portions 12 is 50 mm.
When the diameter of the stirring tank 1 is 600 mm and the height is 1200 mm, the length L of the fin 10 is 670 mm, and a total of three projecting portions 12 are formed at a distance of 50 mm on the upper end of the fin 10 and below the fin 10. Other dimensions are the same as the case where the height of the stirring tank 1 is 600 mm.

回転翼９を駆動して混合液を攪拌すると、旋回流がフィン１０にぶつかって乱流が発生する。突出部１２は矩形でフィン１０の本体部分から幅広く張り出しているので、抵抗が大きくて旋回流がぶつかったときの衝撃は激しく、また、突出部１２にぶつかった混合液の一部は突出部１２間の隙間に流れ込むため、突出部１２が張り出した部分と突出部１２間の隙間とでは流速が異なり、しかも、攪拌槽１内には軸方向の流れも発生する。
このため、燃料油と、水と、乳化剤との混合液は短時間で微細混合され、エマルション燃料となる。 When the rotating blade 9 is driven and the mixed liquid is stirred, the swirling flow collides with the fins 10 to generate turbulent flow. Since the protrusion 12 is rectangular and extends widely from the main body portion of the fin 10, the impact is great when the swirl flow is large due to high resistance. Since it flows into the gap between them, the flow velocity differs between the portion where the protruding portion 12 protrudes and the gap between the protruding portions 12, and an axial flow also occurs in the stirring tank 1.
For this reason, the liquid mixture of fuel oil, water, and an emulsifier is finely mixed in a short time, and becomes an emulsion fuel.

攪拌が終了すると、攪拌槽１内のエマルション燃料は給油路３を通り、切換弁１３及び攪拌パイプ４を経て燃料備蓄槽２へ移送され、ここに備蓄される。
燃料備蓄槽２に長時間貯蔵しておくと、エマルション燃料が油と水とに分離してしまうので、燃料備蓄槽２内のエマルション燃料は、定期的に循環路５及び攪拌パイプ４を通して循環させる。 When the stirring is completed, the emulsion fuel in the stirring tank 1 passes through the oil supply passage 3 and is transferred to the fuel storage tank 2 through the switching valve 13 and the stirring pipe 4 and stored therein.
When stored in the fuel storage tank 2 for a long time, the emulsion fuel is separated into oil and water, so the emulsion fuel in the fuel storage tank 2 is periodically circulated through the circulation path 5 and the stirring pipe 4. .

図５に示すように、攪拌パイプ４は、長さ２００ｍｍ、外径３０ｍｍ程度の寸法を有し、内部の流路は両端において最も太く、軸方向中間部において最も細くなっており、両端の内径が約１６ｍｍ、軸方向中間部の内径が約５ｍｍである。
攪拌パイプ４の軸方向中間部には、内径が全長に亘って均一な円柱状流路１７を形成してある。円柱状流路１７の長さは約１０ｍｍとする。
また、攪拌パイプ４の内面は、図６の（ア）に示すように、その一端から軸方向中間部の円柱状流路１７に向けて階段状に段階的に径が狭くなり、図６の（イ）に示すように、軸方向中間部の円柱状流路１７から他端に向けて階段状に段階的に径が広くなる多数の段１６を有する。 As shown in FIG. 5, the stirring pipe 4 has a length of about 200 mm and an outer diameter of about 30 mm, and the internal flow path is the thickest at both ends and the thinnest at the intermediate portion in the axial direction. Is about 16 mm, and the inner diameter of the intermediate portion in the axial direction is about 5 mm.
A cylindrical flow path 17 having an inner diameter that is uniform over the entire length is formed at an axially intermediate portion of the stirring pipe 4. The length of the cylindrical channel 17 is about 10 mm.
Further, as shown in FIG. 6A, the inner surface of the stirring pipe 4 gradually decreases in diameter stepwise from one end thereof toward the cylindrical channel 17 at the axially intermediate portion. As shown in (a), it has a large number of steps 16 whose diameter gradually increases stepwise from the cylindrical channel 17 at the axially intermediate portion toward the other end.

従って、エマルション燃料を攪拌パイプ４に通すと、階段状に段階的に径が狭まっていく部分では、多数の段１６にぶつかって攪拌される。円柱状流路１７は、流路断面積が小さいので流速は上昇し、それに反比例して圧力が低下し、他端に向かって階段状に段階的に径が広がる部分では、流路断面積が増大し、流速が下がって圧力が増し、流速及び圧力が急激に段階的に変化することにより攪拌される。   Therefore, when the emulsion fuel is passed through the stirring pipe 4, it is agitated by hitting a large number of steps 16 in a portion where the diameter gradually decreases stepwise. The cylindrical channel 17 has a small channel cross-sectional area, so that the flow velocity increases, the pressure decreases in inverse proportion to it, and the channel cross-sectional area increases in a stepwise manner toward the other end. Stirring is achieved by increasing, decreasing the flow rate, increasing the pressure, and rapidly and gradually changing the flow rate and pressure.

エマルション燃料を使用する時は、切換弁１４を切り換えて燃料備蓄槽２から燃料排出路１５を通り、サービスタンク７を経て燃焼装置８へエマルション燃料を送る。
なお、攪拌パイプ４は軸方向中間部を挟んで両側が同じ形状となっているので、エマルション燃料を循環させる際に、攪拌パイプ４の一端から他端に向かってエマルション燃料を流しても、他端から一端に向かってエマルション燃料を流しても同様に攪拌することができる。
また、攪拌パイプ４の寸法は、処理するエマルション燃料の量に応じて適宜調整する。 When using the emulsion fuel, the changeover valve 14 is switched, the emulsion fuel is sent from the fuel storage tank 2 through the fuel discharge path 15 to the combustion device 8 through the service tank 7.
In addition, since the stirring pipe 4 has the same shape on both sides with respect to the intermediate portion in the axial direction, when the emulsion fuel is circulated, even if the emulsion fuel flows from one end to the other end of the stirring pipe 4, other Even if the emulsion fuel is allowed to flow from one end to the other, stirring can be similarly performed.
Moreover, the dimension of the stirring pipe 4 is suitably adjusted according to the quantity of the emulsion fuel to process.
