Description
本発明は船舶、発電機等のボイラ（以下、「船舶等」という。）の燃料油移送装置に係り、特に燃料油澄タンクおよび／または燃料油サービスタンク中の加熱された燃料油の停止中の自然流下ないしは逆流を防止する燃料油移送装置に関する。 TECHNICAL FIELD The present invention relates to a fuel oil transfer device for a boiler such as a ship or a generator (hereinafter referred to as “ship or the like”), and in particular, during the stop of heated fuel oil in a fuel oil tank and / or a fuel oil service tank. The present invention relates to a fuel oil transfer device that prevents natural flow or reverse flow of water.
船舶等において、燃料油を機関に供給する際に、通常、まず、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、次いで、この燃料油澄タンクから燃料油サービスタンク（燃料油小出タンク）に送り、ここから燃料油を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、加温されることが必要である。 When supplying fuel oil to an engine in a ship or the like, usually, the fuel oil is first sent from a fuel oil storage tank to a fuel oil tank through a transfer pipe by a transfer pump, and then from the fuel oil tank to a fuel oil service. It is sent to a tank (fuel oil dispensing tank), from which fuel oil is supplied to the engine. 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.
この種の加温設備を有する燃料油移送装置として、従来、図１における弁１５を備えない装置、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、または両方中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１において、８はヒータ、９は温度センサー、１０、１１、１２、１３はバルブである。 Conventionally, as a fuel oil transfer device having this kind of heating equipment, a device that does not include the valve 15 in FIG. 1, that is, a fuel oil storage tank 1 and a heating device (not shown) communicated with this via a transfer pipe 2. A fuel oil tank 3, a transfer pump 4 for transferring the fuel oil in the fuel oil storage tank 1 to the fuel oil tank 3, and 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, or both of the fuel oil tank 3 and the fuel oil service tank 5 are connected to the fuel oil storage tank 1. There is known an apparatus provided with a flow-down pump 7 for flowing the heated fuel oil in either one or both of them into the fuel oil storage tank 1. In FIG. 1, 8 is a heater, 9 is a temperature sensor, 10, 11, 12, and 13 are valves.
上述の弁１５を有しない図１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 of FIG. 1 that does not have the valve 15 described above, the fuel oil in the fuel oil tank 3 is heated by a heating device (not shown), and then cleaned by a fuel oil purifier (not shown) and sent to the fuel oil service tank 5. From here, it is distributed and supplied to a main machine, auxiliary machines, boilers and the like (not shown). 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.
上述の弁１５を有しない図１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、外気の温度変化に対応して変化させる必要がある。 In the apparatus of FIG. 1 that does not have the valve 15 described above, 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 to add the fuel oil in the tank 1. When warming, 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, or the temperature change of seawater and outside air.
すなわち、もどされる加熱された燃料油の熱量が適正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正に保つ必要がある。 That is, when the amount of heat of the heated fuel oil to be returned is larger than the appropriate value, the heat dissipation of the heat amount to the seawater or the outside air is increased, 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 returned properly.
しかし、上述の弁１５を備えない図１装置では、澄タンクおよび／またはサービスタンク中の加熱された燃料油の一部を燃料油貯蔵タンクに流下させる際に、燃料油は燃料油貯蔵タンクにもどらずに移送管方向に逆流してしまう。また、燃料油貯蔵タンクからの燃料油を移送管方向に送る際に空気の泡が発生してしまう。 However, in the apparatus of FIG. 1 that does not include the valve 15 described above, when a part of the heated fuel oil in the clarification tank and / or the service tank is caused to flow down to the fuel oil storage tank, the fuel oil enters the fuel oil storage tank. It does not return and flows backward in the direction of the transfer pipe. Also, air bubbles are generated when the fuel oil from the fuel oil storage tank is sent in the direction of the transfer pipe.
さらに、上述の弁１５を移送管２のみにしか備えない図１装置も知られている。（特許第３８０７５９７号） Furthermore, the apparatus of FIG. 1 is also known in which the valve 15 described above is provided only in the transfer pipe 2. (Patent No. 3807597)
この燃料油移送装置は停止中においても、入口側（吸入側）の圧力が高く、出口側（吐出側）の圧力が低い場合がほとんどである。これは燃料油澄タンク（ポンプの吸入側）が燃料油貯蔵タンク（ポンプの吐出側）より高いことによる。したがって、装置の停止中でも、この圧力により、意図せずに澄タンクおよび／またはサービスタンクから貯蔵タンクに自然に油が流れることになる。 Even when the fuel oil transfer device is stopped, the pressure on the inlet side (suction side) is high and the pressure on the outlet side (discharge side) is mostly low. This is because the fuel oil tank (pump suction side) is higher than the fuel oil storage tank (pump discharge side). Therefore, even when the apparatus is shut down, this pressure causes unintentional flow of oil from the clear tank and / or service tank to the storage tank.
そこで、本発明の解決しようとする課題は燃料油澄タンクおよび／または燃料油サービスタンク中の加熱された燃料油の運転停止中の自然流下ないしは逆流を防止する前述の公知技術に存する欠点を改良した燃料油移送装置を提供することにある。 Therefore, the problem to be solved by the present invention is to improve the drawbacks of the above-mentioned known techniques for preventing the natural flow or back flow of the heated fuel oil in the fuel oil tank and / or the fuel oil service tank during shutdown. Another object of the present invention is to provide a fuel oil transfer device.
上述の課題を解決するため、本発明によれば、吸入主管を備えた燃料油貯蔵タンクと、この貯蔵タンクに移送管を介して連通された燃料油澄タンクと、この移送管に設けられ、
移送管を通して前記貯蔵タンク中の燃料油を前記澄タンクに移送する移送ポンプと、前記澄タンクと連通した燃料油サービスタンクと、前記澄タンクおよび／または前記サービスタンクと前記貯蔵タンクとを連通する吸入管と、この吸入管に配置され、前記澄タンクおよび／または前記サービスタンク中の加熱された燃料油を前記貯蔵タンクに流下せしめる流下ポンプとを備え、前記加熱された燃料油を前記貯蔵タンクの燃料油に吸入主管を通して流下混合して前記貯蔵タンク中の燃料油を加熱する燃料油移送装置において、前記移送管の移送ポンプよりも下流側にスプリングを保持したバルブを設け、さらに吸入管の流下ポンプよりも下流側にもスプリングを保持したバルブを設け、前記スプリングは任意の圧力に設定し得、このようなスプリングを保持したバルブはスプリングの押圧力によって弁押えを弁座に当接し、加熱された燃料油の移送管への逆流を防止し、さらに、吸入管への流下を防止してなり、これにより前記澄タンクおよび／またはサービスタンク中の加熱された燃料油を移送管に逆流させずに、さらに前記澄タンクおよび／またはサービスタンク中の加熱された燃料油を吸入管に流下させずに、自然流下を防止しながら前記貯蔵タンクに移送することを特徴とする。
In order to solve the above-described problem, according to the present invention, a fuel oil storage tank provided with a suction main pipe, a fuel oil tank connected to the storage tank via a transfer pipe, and the transfer pipe are provided.
A transfer pump for transferring fuel oil in the storage tank to the clarifier tank through a transfer pipe, a fuel oil service tank in communication with the clarifier tank, and the clarifier tank and / or the service tank and the storage tank in communication. A suction pipe, and a flow-down pump disposed in the suction pipe and configured to flow the heated fuel oil in the clarification tank and / or the service tank to the storage tank, and the heated fuel oil is supplied to the storage tank. In the fuel oil transfer device for heating and mixing the fuel oil in the storage tank by flowing down through the main suction pipe, a valve holding a spring is provided on the downstream side of the transfer pump of the transfer pipe. A valve holding a spring is also provided downstream of the downflow pump, and the spring can be set to an arbitrary pressure. The valve holding the ring abuts the valve presser against the valve seat by the pressing force of the spring, prevents the backflow of heated fuel oil to the transfer pipe, and further prevents the flow down to the suction pipe. The heated fuel oil in the clarification tank and / or service tank does not flow back to the transfer pipe, and the heated fuel oil in the clarification tank and / or service tank does not flow down to the intake pipe. It transfers to the said storage tank, preventing a flow down.
上述の本発明は移送管の移送ポンプよりも下流側にスプリングを保持したバルブを設け、さらに吸入管の流下ポンプよりも下流側にもスプリングを保持したバルブを設けたから、加熱された燃料油の移送管への逆流を防止し、さらに吸入管への流下を防止し、これにより澄タンクおよび／またはサービスタンク中の加熱された燃料油を移送管に逆流させずに、さらに吸入管にも流下させずに自然流下を防止する。 In the present invention described above, the valve holding the spring is provided downstream of the transfer pump of the transfer pipe, and the valve holding the spring is provided further downstream of the downflow pump of the suction pipe. Prevents backflow to the transfer pipe, and further prevents flow to the suction pipe, so that the heated fuel oil in the clarification tank and / or service tank does not flow back to the transfer pipe, but also flows to the suction pipe. Prevent natural flow without letting.
図１において、本発明の燃料油移送装置は吸入主管１４を備えた燃料油貯蔵タンク１と、この貯蔵タンク１に移送管２を介して連通された燃料油澄タンク３と、移送管２に設けられ、この移送管２を通して貯蔵タンク１中の燃料油を澄タンク３に移送する移送ポンプ４と、澄タンク３と連通した燃料油サービスタンク５と、澄タンク３および／またはサービスタンク５と貯蔵タンク１とを連通する吸入管６と、この吸入管６に配置され、澄タンク３および／またはサービスタンク５中の加熱された燃料油を貯蔵タンク１に流下せしめる流下ポンプ７とを備え、加熱された燃料油を貯蔵タンク１の燃料油に吸入主管１４を通して流下混合して貯蔵タンク１中の燃料油を加熱するようにしたものである。図１中、８はヒータ、９は温度センサ、１０、１１、１２、１３はバルブである。 In FIG. 1, the fuel oil transfer device of the present invention includes a fuel oil storage tank 1 having a suction main pipe 14, a fuel oil tank 3 communicated with the storage tank 1 via a transfer pipe 2, and a transfer pipe 2. A transfer pump 4 for transferring the fuel oil in the storage tank 1 to the clear tank 3 through the transfer pipe 2, a fuel oil service tank 5 communicating with the clear tank 3, a clear tank 3 and / or a service tank 5; A suction pipe 6 communicating with the storage tank 1, and a flow-down pump 7 disposed in the suction pipe 6 and allowing the heated fuel oil in the clarification tank 3 and / or the service tank 5 to flow down to the storage tank 1, The heated fuel oil is mixed with the fuel oil in the storage tank 1 through the suction main pipe 14 to heat the fuel oil in the storage tank 1. In FIG. 1, 8 is a heater, 9 is a temperature sensor, 10, 11, 12, and 13 are valves.
そして、上述の本発明装置において、改良の主ポイントは移送管２の移送ポンプ４よりも下流側にスプリング１６を保持した弁１５を設け、さらに、吸入管６の流下ポンプ７よりも下流側にも、スプリング１６を保持した弁１５を設けたことに存し、これにより澄タンク３および／またはサービスタンク５中の加熱された燃料油を移送管２の方向に逆流させずに、さらに、前記澄タンク３および／またはサービスタンク５中の加熱された燃料油を吸入管６に流下させずに、自然流下を防止しながら、前記貯蔵タンク１に流下せしめるようにしたことを特徴とする。 In the above-described apparatus of the present invention, the main point of improvement is that a valve 15 holding a spring 16 is provided on the downstream side of the transfer pump 4 of the transfer pipe 2 and further on the downstream side of the downflow pump 7 of the suction pipe 6. In addition, the valve 15 holding the spring 16 is provided, so that the heated fuel oil in the clarification tank 3 and / or the service tank 5 does not flow backward in the direction of the transfer pipe 2, and The heated fuel oil in the clarification tank 3 and / or the service tank 5 is allowed to flow down to the storage tank 1 while not flowing down to the suction pipe 6 while preventing it from flowing down.
図２は弁１５の閉じた状態、図３は開いた状態の断面図であり、運転休止中は図２に示されるように、ハンドル１８を閉めて、弁押え２１を弁座２２に当接させておく。この状態では入り口１９からの燃料油は出口２０に進行することがない。 2 is a cross-sectional view of the valve 15 in a closed state, and FIG. 3 is a cross-sectional view of the valve 15 in an open state. During operation stop, the handle 18 is closed and the valve presser 21 is brought into contact with the valve seat 22 as shown in FIG. Let me. In this state, the fuel oil from the inlet 19 does not travel to the outlet 20.
運転中、通常は図３に示されるようにハンドル１８を開け、弁棒２３を上方に上げた状態にしておく。この状態でも、通常はスプリング１６の押圧力によって弁押え２１が座金１７を介して弁座２２に押圧される。このため弁押え２１は弁座２２に当接しており、入口１９からの燃料油は弁押え２１で阻止されて出口２０へは通じない。したがって、加熱された燃料油が移送管２の方向に逆流されることは防止され、かつ、加熱された燃料油が吸入管６の方向に自然流下されることも防止される。同時に、燃料油貯蔵タンク１から吸入主管１４を経て発生した空気泡もつぶされて消えてしまう。 During operation, the handle 18 is normally opened as shown in FIG. 3, and the valve stem 23 is raised upward. Even in this state, the valve presser 21 is normally pressed against the valve seat 22 via the washer 17 by the pressing force of the spring 16. For this reason, the valve presser 21 is in contact with the valve seat 22, and fuel oil from the inlet 19 is blocked by the valve presser 21 and does not pass to the outlet 20. Therefore, the heated fuel oil is prevented from flowing backward in the direction of the transfer pipe 2, and the heated fuel oil is also prevented from flowing naturally in the direction of the suction pipe 6. At the same time, air bubbles generated from the fuel oil storage tank 1 through the suction main pipe 14 are crushed and disappear.
スプリング１６は任意の圧力、例えば約０.０９８ＭＰａ．１.０Ｋｇｆ／ｃｍ２（全開時）に設定することができる。これにより、燃料油貯蔵タンク１からの加熱された燃料油は入口１９から弁押え２１を押し上げて出口２０方向に流れる。このとき、空気で発生して泡も圧力により消去する。 The spring 16 can be of any pressure, for example about 0.098 MPa. It can be set to 1.0 kgf / cm 2 (when fully open). Thereby, the heated fuel oil from the fuel oil storage tank 1 pushes up the valve presser 21 from the inlet 19 and flows in the direction of the outlet 20. At this time, bubbles generated by air are also erased by pressure.
本発明にかかる燃料油移送装置は移送管２の移送ポンプ４および吸入管６の流下ポンプ７よりも下流側にそれぞれスプリング１６を保持した弁１５を設けたから、澄タンク３および／またはサービスタンク５中の加熱された燃料油を移送管２に逆流させずに、かつ、吸入管６に自然流下させずに前記貯蔵タンクに流下せしめ、かつ、移送管２中の空気泡も、自動的につぶれて消えてしまい、産業上の利用可能性が高い。 Since the fuel oil transfer device according to the present invention is provided with the valve 15 holding the spring 16 on the downstream side of the transfer pump 4 of the transfer pipe 2 and the downflow pump 7 of the suction pipe 6, the clear tank 3 and / or the service tank 5 are provided. The heated fuel oil is not allowed to flow back to the transfer pipe 2 and is not allowed to flow naturally to the suction pipe 6 and is allowed to flow into the storage tank, and air bubbles in the transfer pipe 2 are automatically crushed. Disappears and the industrial applicability is high.
