Description

本発明は船舶等における燃料油貯蔵タンク中の燃料油の加熱方法に係り、詳細には、澄タンクで加熱された燃料油を澄タンクやサービスタンクから貯蔵タンクに流下混合して該タンク中の燃料油を所望温度に加温する加熱方法に係り、特にタンク中の燃料油の加温効率を部分的に向上させる燃料油貯蔵タンク中の燃料油の加熱方法に関する。   The present invention relates to a method for heating fuel oil in a fuel oil storage tank in a ship or the like. Specifically, fuel oil heated in a clear tank flows down from a clear tank or a service tank to a storage tank and is mixed in the tank. The present invention relates to a heating method for heating fuel oil to a desired temperature, and more particularly to a heating method for fuel oil in a fuel oil storage tank that partially improves the heating efficiency of the fuel oil in the tank.

船舶等において、燃料油を機関に供給する際に、通常、燃料油を燃料油貯蔵タンクから移送ポンプによって移送管を通して燃料油澄タンクに送り、ここで燃料油を加熱の後、燃料油サービスタンク（燃料油小出タンク）および燃料油清浄機等を介して機関に供給している。このとき、燃料油貯蔵タンク中の燃料油は粘度を低くして移送しやすくするために加温することが必要である。   When supplying fuel oil to an engine in a ship or the like, the fuel oil is usually sent from a fuel oil storage tank to a fuel oil tank through a transfer pipe by a transfer pump, where the fuel oil is heated and then the fuel oil service tank. It is supplied to the engine via a (fuel oil dispensing tank) and a fuel oil purifier. At this time, the fuel oil in the fuel oil storage tank needs to be heated in order to reduce the viscosity and facilitate transfer.

この種の加温設備として、従来、図８の設備、すなわち、燃料油貯蔵タンク１と、これと移送管２を介して連通された図示しない加熱装置を備えた燃料油澄タンク３と、燃料油貯蔵タンク１中の燃料油を燃料油澄タンク３に移送するための移送ポンプ４と、燃料油澄タンク３に連通された燃料油サービスタンク５と、燃料油澄タンク３および燃料油サービスタンク５のいずれか一方、または両方を燃料油貯蔵タンク１に連通する吸入管６と、吸入管６に設けられ、燃料油澄タンク３および燃料油サービスタンク５のいずれか一方、または両方の加熱された燃料油を燃料油貯蔵タンク１に流下せしめる流下ポンプ７とを備えた装置が知られている。図８において、８はヒータ、９は温度センサ、１０、１１、１２、１３はそれぞれバルブである。   Conventionally, as this type of heating equipment, the equipment shown in FIG. 8, that is, a fuel oil storage tank 1, a fuel oil tank 3 equipped with a heating device (not shown) communicated with the fuel oil storage tank 1, and a fuel, A transfer pump 4 for transferring the fuel oil in the oil storage tank 1 to the fuel oil tank 3, a fuel oil service tank 5 communicated with the fuel oil tank 3, the fuel oil tank 3 and the fuel oil service tank 5, a suction pipe 6 communicating with one or both of the fuel oil storage tank 1 and a suction pipe 6, and either one or both of the fuel oil tank 3 and the fuel oil service tank 5 are heated. There is known an apparatus including a flow-down pump 7 that causes the fuel oil to flow down to the fuel oil storage tank 1. In FIG. 8, 8 is a heater, 9 is a temperature sensor, 10, 11, 12, and 13 are valves.

上述の図８装置では、燃料油澄タンク３中の燃料油は図示しない加熱装置により加熱され、次いで図示しない燃料油清浄機で清浄されて燃料油サービスタンク５に送り込まれ、ここから図示しない主機、補機、ボイラ等に分配供給される。同時に、この加熱された燃料油の一部は流下ポンプ７の作動により燃料油貯蔵タンク１に該タンク１中の吸入主管１４を通して流下され、該タンク１中の燃料油を加温する。   In the apparatus shown in FIG. 8, the fuel oil in the fuel oil tank 3 is heated by a heating device (not shown), then cleaned by a fuel oil cleaner (not shown) and sent to the fuel oil service tank 5, from which the main machine (not shown) , Distributed and supplied to auxiliaries, boilers, etc. At the same time, part of the heated fuel oil is caused to flow down to the fuel oil storage tank 1 through the suction main pipe 14 in the tank 1 by the operation of the flow down pump 7, and the fuel oil in the tank 1 is heated.

上述の図８装置において、加熱された燃料油の一部を燃料油澄タンク３ないしは燃料油サービスタンク５から燃料油貯蔵タンク１にもどして該タンク１中の燃料油を加温するとき、このもどす量および温度は吸入管６や移送管２の長さ、あるいは海水や、外気の温度変化、さらには燃料油貯蔵タンク１の大きさに対応して変化させる必要がある。   In the apparatus shown in FIG. 8, when a part of the heated fuel oil is returned from the fuel oil tank 3 or the fuel oil service tank 5 to the fuel oil storage tank 1, the fuel oil in the tank 1 is heated. The amount and temperature to be returned need to be changed in accordance with the length of the suction pipe 6 and the transfer pipe 2, the temperature change of seawater and outside air, and the size of the fuel oil storage tank 1.

すなわち、もどされる加熱された燃料油の熱量が適性値より多い場合には、海水や外気への熱量の放熱が多くなり、少ない場合には、所要量の燃料油の移送ができなくなり、このため、もどされる加熱された燃料油の量と温度を適性に保つ必要がある。   That is, when the amount of heat of the heated fuel oil to be returned is greater than the appropriate value, the amount of heat released to the seawater and the outside air increases, and when it is less, the required amount of fuel oil cannot be transferred, It is necessary to keep the amount and temperature of the heated fuel oil to be returned adequate.

しかし、上述の図８装置では、燃料油貯蔵タンク１に吸入主管１４を通してもどされた加熱燃料油は温度が高くて比重が軽いため、すぐにタンク１内の上方に上昇してしまい、あるいは貯蔵タンク１全体に拡散し、放熱されてしまう。このため、吸入主管１４の周辺は高粘度な冷温油のままであり、吸入主管１４からの吸入が不良となり、熱効率がよくない。   However, in the above-described FIG. 8 apparatus, the heated fuel oil returned to the fuel oil storage tank 1 through the suction main pipe 14 has a high temperature and a low specific gravity, so that it immediately rises in the tank 1 or is stored. It diffuses throughout the tank 1 and is dissipated. For this reason, the periphery of the suction main pipe 14 remains a high-viscosity cold and hot oil, and suction from the suction main pipe 14 becomes poor, resulting in poor thermal efficiency.

特に、図１および図２に示されるように、船底１５に水のバラストタンク１６を設け、その上に燃料油貯蔵タンク１を設け、さらにその上に荷物層１７を設けて構成される三重底タイプの船舶Ａでは図１に示されるように、燃料油貯蔵タンク１内に区切りがなく、広くなっており、このため、加熱された燃料油はタンク１全体にすぐに拡散され、燃料油貯蔵タンク１中の燃料油の加温が難しい。   In particular, as shown in FIGS. 1 and 2, a triple bottom constructed by providing a water ballast tank 16 on a ship bottom 15, a fuel oil storage tank 1 thereon, and a luggage layer 17 thereon. As shown in FIG. 1, in the type of ship A, there is no separation in the fuel oil storage tank 1 and it is wide. Therefore, the heated fuel oil is immediately diffused throughout the tank 1 to store the fuel oil. It is difficult to heat the fuel oil in the tank 1.

この問題を解決する手段として、従来、貯蔵タンク１内の吸入主管１４前につい立てを建立して加熱された燃料油の拡散を防ごうとする装置が知られている〔特願２００１−１１５２９３（特開２００２−３０８３９９）参照〕。   As a means for solving this problem, conventionally, there has been known a device that is designed to prevent diffusion of heated fuel oil by erecting a stand in front of the suction main pipe 14 in the storage tank 1 [Japanese Patent Application No. 2001-115293 ( JP 2002-308399)].

しかし、この装置の場合、高いないしは深い燃料タンクでは効果が大きいが、低い平らなタンクでは施工コストがかかる。
特願２００２−１９８４０８ 特願２００１−１１５２９３（特開２００２−３０８３９９） However, in the case of this apparatus, a high or deep fuel tank is effective, but a low flat tank has a construction cost.
Japanese Patent Application 2002-198408 Japanese Patent Application No. 2001-115293 (JP 2002-308399)

そこで、本発明の課題は加熱された燃料油を澄タンクやサービスタンクから貯蔵タンクに流下混合して該タンク中の燃料油を所望の温度に加温するに際し、タンク中の燃料油加温効率を部分的に向上させ、上述の公知技術に存する欠点を改良した燃料油貯蔵タンクを提供することにある。   Accordingly, an object of the present invention is to mix the heated fuel oil from the clarification tank or the service tank to the storage tank and warm the fuel oil in the tank to a desired temperature. It is an object of the present invention to provide a fuel oil storage tank that partially improves the above-mentioned problems and improves the above-mentioned drawbacks of the known art.

上述の課題を解決するための、本発明の燃料油貯蔵タンク中の加熱方法によれば、加熱された燃料油を燃料油貯蔵タンク中の燃料油に、該タンク内に開孔された吸入主管を通して流下混合し、前記燃料油貯蔵タンク中の燃料油を加温する加熱方法において、区切り板を複数枚、燃料油貯蔵タンク内で縦方向および横方向に間隔をあけて配置して複数のボックス状小区画を縦および横方向に互いに隣接して形成し、いずれか一方のボックス状小区画内に吸入主管の先端が位置するとともに、各ボックス状小区画が区切り板に設けられた孔を通して互いに連通されてなることを特徴とする。
According to the heating method in the fuel oil storage tank of the present invention for solving the above-described problem, the heated fuel oil is converted into the fuel oil in the fuel oil storage tank, and the suction main pipe opened in the tank. In the heating method in which the fuel oil in the fuel oil storage tank is heated by being mixed down and through , a plurality of separator plates are arranged in the fuel oil storage tank with a plurality of boxes arranged at intervals in the vertical and horizontal directions. Are formed adjacent to each other in the vertical and horizontal directions, and the tip of the suction main pipe is located in one of the box-shaped small sections, and each box-shaped small section is mutually connected through a hole provided in the partition plate. It is characterized by being communicated.

上述の本発明は吸入主管の先端周辺を区切り板で囲って先端をボックス状の小区画内に位置するようにしたから、先端を通して燃料油中に流入された加熱燃料油は拡散放熱が防止され、ボックス状小区画内の燃料油は効率よく加熱され、粘度が低くなって移送しやすくなる。   In the above-described present invention, the periphery of the tip of the suction main pipe is surrounded by the partition plate so that the tip is positioned in the box-shaped small section, so that the heated fuel oil flowing into the fuel oil through the tip is prevented from diffusing and radiating heat. The fuel oil in the box-shaped small section is efficiently heated, and the viscosity becomes low, so that it can be easily transported.

A transfer pump 4 for transferring fuel oil to the fuel oil tank 3, a fuel oil service tank 5 communicated with the fuel oil tank 3, and one of the fuel oil tank 3 and the fuel oil service tank 5, Alternatively, a suction pipe 6 that communicates both with the fuel oil storage tank 1, and one of the fuel oil tank 3 and the fuel oil service tank 5, or both heated fuel oils are provided in the fuel pipe. A flow-down pump 7 that flows down to the storage tank 1 is provided. In FIG. 8, 8 is a heater, 9 is a temperature sensor, 10, 11, 12, and 13 are valves.

上述図８において、燃料油澄タンク３中の燃料油は図示しない加熱装置により加熱され、次いで図示しない燃料油清浄機で清浄されて燃料油サービスタンク５に送り込まれ、ここから図示しない主機、補機、ボイラ等に分配供給される。同時にこの加熱された燃料油の一部は流下ポンプ７の作動により燃料油貯蔵タンク１に該タンク１中の吸入主管１４を通して流下され、該タンク１中の燃料油を加温する。   In FIG. 8 described above, the fuel oil in the fuel oil tank 3 is heated by a heating device (not shown), then cleaned by a fuel oil cleaner (not shown), and sent to the fuel oil service tank 5, from which the main engine and auxiliary equipment (not shown) Distributed to machine and boiler. At the same time, part of the heated fuel oil is caused to flow down to the fuel oil storage tank 1 through the suction main pipe 14 in the tank 1 by the operation of the flow down pump 7, and the fuel oil in the tank 1 is heated.

本発明の特徴は参考例にかかる図３に示されるように、タンク１内を設置された吸入主管１４の先端１８周辺を一枚の区切り板１９で燃料油貯蔵タンク１を横切る方向に配置して囲み、燃料油貯蔵タンク１内にボックス状小区画２０を形成したことに存する。これにより、先端１８はボックス状小区画２０内に配置される。図３中、区切り板１９の上面には、エア抜き用孔２１が好ましくは複数個穿設され、下側には油通過用孔２２が好ましくは複数個穿設される。なお、孔２３は比較的大きな孔であって、油通過用ないしは人通行用の孔である。

FIG. 5 shows still another example of the fuel oil storage tank 1 as a reference example , in which a plurality of separator plates 19, 19... 19 are arranged at intervals in a direction crossing the fuel oil storage tank 1. A plurality of box-shaped subsections 20, 20,... 20 are formed adjacent to each other, and the tip of the suction main pipe 14 is disposed in one of the box-shaped subsections 20, for example, in the left box-shaped subsection 20 18 is located, and each box-shaped small section 20, 20... 20 is communicated with each other through holes 23, 23.

図６は本発明にかかる燃料油貯蔵タンク１であって、複数の区切り板１９、１９・・・１９を、燃料油貯蔵タンク１内で縦方向および横方向に間隔をあけて配置して複数のボックス状小区画２０、２０・・・２０を縦方向および横方向に互いに隣接して形成し、かつ、いずれか一方のボックス状小区画２０内に、例えば、左下のボックス状小区画２０内に吸入主管１４の先端１８が位置するとともに、各ボックス状小区画２０、２０・・・２０が区切り板１９に設けられた孔２３を通して互いに連通される。
FIG. 6 shows a fuel oil storage tank 1 according to the present invention, in which a plurality of separator plates 19, 19... 19 are arranged in the fuel oil storage tank 1 at intervals in the vertical and horizontal directions. Are formed adjacent to each other in the vertical direction and the horizontal direction, and in one of the box-shaped small sections 20, for example, in the box-shaped small section 20 on the lower left In addition, the distal end 18 of the suction main pipe 14 is positioned, and the box-shaped small sections 20, 20... 20 are communicated with each other through holes 23 provided in the partition plate 19.

図７は本発明にかかる他の例の燃料油貯蔵タンク１であって、複数の区切り板１９、１９・・・１９を、燃料油貯蔵タンク１内で縦方向および横方向に間隔をあけて配置して複数のボックス状小区画２０、２０・・・２０を縦方向および横方向に互いに隣接してＴ字形状に形成する。そして、いずれか一方のボックス状小区画２０内に、例えば、中央のボックス状小区画２０の下方外側に吸入主管１４が位置し、先端１８のみがボックス状小区画２０の内側に開孔する。さらに、各ボックス状小区画２０、２０・・・２０は区切り板１９に設けられた孔２３を通して互いに連通される。
FIG. 7 shows another example of the fuel oil storage tank 1 according to the present invention, in which a plurality of separator plates 19, 19... 19 are spaced in the fuel oil storage tank 1 in the vertical and horizontal directions. A plurality of box-shaped small sections 20, 20... 20 are formed in a T-shape adjacent to each other in the vertical and horizontal directions. Then, in any one of the box-shaped small sections 20, for example, the suction main pipe 14 is positioned on the lower outside of the central box-shaped small section 20, and only the tip 18 is opened inside the box-shaped small section 20. Further, the box-shaped small sections 20, 20... 20 are communicated with each other through a hole 23 provided in the partition plate 19.

すなわち、吸入主管１４は図３、図４、図５および図６に示されるように、先端がベルマウスで形成され、全体が燃料油貯蔵タンク1内に配置されてもよい。また、吸入主管１４は図７に示されるように、吸入主管１４の本体が燃料油貯蔵タンク１の外側に配置され、先端１８のみが燃料油貯蔵タンク1内に開孔されてもよい。   That is, as shown in FIGS. 3, 4, 5, and 6, the suction main pipe 14 may be formed with a bell mouth at the tip, and may be disposed in the fuel oil storage tank 1 as a whole. Further, as shown in FIG. 7, the main body of the suction main pipe 14 may be disposed outside the fuel oil storage tank 1, and only the tip 18 may be opened in the fuel oil storage tank 1.

上述図３、図４、図５、図６および図７にかかる燃料油貯蔵タンク１は吸入主管１４の先端１８が燃料油貯蔵タンク１内に形成されたボックス状小区画２０に位置するため、先端１８を通じて燃料油澄タンク３ないしは燃料油サービスタンク５から流入された加熱燃料油はボックス状小区画２０によって拡散、放熱が防止され、燃料油の加温効率がボックス状小区画２０内で部分的に向上する。
The fuel oil storage tank 1 according to FIGS. 3, 4, 5, 6, and 7 is located at the box-shaped subcompartment 20 formed in the fuel oil storage tank 1 at the tip 18 of the suction main pipe 14. The heated fuel oil flowing from the fuel oil tank 3 or the fuel oil service tank 5 through the tip 18 is prevented from diffusing and dissipating heat by the box-shaped small section 20, and the heating efficiency of the fuel oil is partially within the box-shaped small section 20. Improve.

燃料油貯蔵タンク１中にボックス状小区画２０を設け、この中に吸入主管１４の先端１８を配置することによって、ボックス状小区画２０内の燃料油が効率良く加温され、燃料油が低粘性になり、このため移送管２を通して燃料油澄タンク３への移送が容易となり、船舶への利用が期待される。   By providing the box-shaped small section 20 in the fuel oil storage tank 1 and disposing the tip 18 of the suction main pipe 14 therein, the fuel oil in the box-shaped small section 20 is efficiently heated, and the fuel oil is low. Therefore, the transfer to the fuel oil tank 3 through the transfer pipe 2 is facilitated, and utilization for a ship is expected.
