　本発明は、燃料供給路の途中に配され、液体燃料中に微細な酸素を含む気体等の気泡を混入させることで燃焼性の高い燃料に改質してボイラー等に送出する燃料改質装置に関する。 The present invention is a fuel reformer that is arranged in the middle of a fuel supply path and reforms into a highly combustible fuel by mixing bubbles such as gas containing fine oxygen into liquid fuel and sends it to a boiler or the like About.
  上記燃料改質装置の一例として、貯留槽と、貯留槽内に配され、酸素等から微細気泡（マイクロバブル）を生成するマイクロバブル生成器とを備え、貯留槽内の燃料に微細気泡を混入させて燃料の改質を行うものが存在する。 As an example of the fuel reformer, a storage tank and a microbubble generator that is arranged in the storage tank and generates microbubbles from oxygen or the like are mixed, and the microbubbles are mixed into the fuel in the storage tank. In some cases, the fuel is reformed.
　しかし、マイクロバブル生成器で生成された微細気泡は、時間の経過によってその径が拡大し、ボイラー等に改質燃料を送出するノズルにおいて、拡径したバブルによって改質燃料の送出が妨げられるという問題が生じた。また、貯留槽内の気体の酸素濃度が高いと、燃焼事故が発生するリスクが高まるという問題もあった。 However, the diameter of the fine bubbles generated by the microbubble generator increases with the passage of time, and in the nozzle that sends the reformed fuel to a boiler or the like, the expanded bubble prevents the reformed fuel from being sent out. There was a problem. Moreover, when the oxygen concentration of the gas in a storage tank is high, there also existed a problem that the risk that a combustion accident will generate | occur | produce increased.
　そこで、特許文献１には、貯留槽内に外気を供給するためのエアーポンプと、貯留槽の上部に接続されてミスト状の燃料及び気体を排出する排気管と、排気管から排出されたミスト状の燃料及び気体を分離する気液分離器と、気液分離器で分離された燃料を貯留槽内に戻すための燃料戻し管と、気液分離器で分離された気体の浄化を行うエアフィルタ等を備える燃料改質装置が開示される。この燃料改質装置によれば、拡径したバブルを外部へ排出することができると共に、外気を供給することで燃焼事故発生のリスクを低減することができる。 Therefore, Patent Document 1 discloses an air pump for supplying outside air into the storage tank, an exhaust pipe connected to the upper part of the storage tank for discharging mist-like fuel and gas, and mist discharged from the exhaust pipe. Gas-liquid separator for separating the fuel and gas in the form of a gas, a fuel return pipe for returning the fuel separated by the gas-liquid separator into the storage tank, and air for purifying the gas separated by the gas-liquid separator A fuel reformer including a filter or the like is disclosed. According to this fuel reformer, the expanded bubble can be discharged to the outside, and the risk of a combustion accident can be reduced by supplying outside air.

　しかし、上記特許文献１に記載の燃料改質装置では、気液分離器やエアフィルタを設ける必要があるために製造コストが増加すると共に、酸素等の微細気泡に用いる気体を損失するという問題があった。さらに、気液分離器や、エアフィルタに異常が生じた場合等には、ミスト状の燃料が外部に漏出するおそれも否定できない。 However, in the fuel reformer described in Patent Document 1, it is necessary to provide a gas-liquid separator and an air filter, which increases the manufacturing cost and causes a problem of loss of gas used for fine bubbles such as oxygen. there were. Furthermore, when an abnormality occurs in the gas-liquid separator or the air filter, there is no denying that mist-like fuel may leak out.
　そこで、本発明は上記従来技術における問題点に鑑みてなされたものであって、製造コストが低く、燃料漏れ等のリスクを低減し、改質燃料を燃焼装置に安定して効率よく供給することのできる燃料改質装置を提供することを目的とする。 Accordingly, the present invention has been made in view of the above-described problems in the prior art, and is low in manufacturing cost, reduces the risk of fuel leakage, etc., and stably and efficiently supplies reformed fuel to the combustion device. An object of the present invention is to provide a fuel reformer that can perform the above-described process.
　上記目的を達成するため、本発明は、燃料改質装置であって、液体燃料を加圧するポンプと、該ポンプによって加圧された前記液体燃料と、気体とが供給され、該液体燃料と該気体とを混合撹拌して該液体燃料中に該気体の微細気泡を生じさせた後貯留槽に吹き込むノズルと、前記貯留槽に貯留された改質燃料を抜き出して燃焼装置に供給する改質燃料供給手段とを備えることを特徴とする。 In order to achieve the above object, the present invention provides a fuel reformer comprising a pump for pressurizing a liquid fuel, the liquid fuel pressurized by the pump, and a gas, and the liquid fuel and the A gas that is mixed and agitated to produce fine bubbles of the gas in the liquid fuel and then blown into a storage tank, and a reformed fuel that is extracted from the reformed fuel stored in the storage tank and supplied to the combustion device And a supply means.
　本発明によれば、ノズルによって加圧した液体燃料と気体とを混合撹拌して液体燃料中に気体の微細気泡を生じさせた後貯留槽に吹き込むため、気液分離器やエアフィルタが不要となり、製造コストを低減することができる。また、ミスト状の燃料が外部に漏出するおそれもなく、改質燃料を燃焼装置に安定して効率よく供給することができる。 According to the present invention, since the liquid fuel pressurized by the nozzle and the gas are mixed and agitated to generate fine gas bubbles in the liquid fuel and then blown into the storage tank, a gas-liquid separator and an air filter become unnecessary. The manufacturing cost can be reduced. Further, there is no fear that the mist-like fuel leaks to the outside, and the reformed fuel can be stably and efficiently supplied to the combustion device.
　また、本発明は、燃料改質装置であって、気体を貯留槽に搬送する気体搬送管と、液体燃料を加圧するポンプと、該ポンプによって加圧された前記液体燃料と、前記貯留槽の上部に滞留する前記気体とが供給され、該液体燃料と該気体とを混合撹拌して該液体燃料中に該気体の微細気泡を生じさせた後前記貯留槽に吹き込むノズルと、前記貯留槽に貯留された改質燃料を抜き出して燃焼装置に供給する改質燃料供給手段とを備えることを特徴とする。 The present invention is also a fuel reformer, a gas transport pipe for transporting gas to a storage tank, a pump for pressurizing liquid fuel, the liquid fuel pressurized by the pump, and the storage tank The gas staying in the upper part is supplied, and the liquid fuel and the gas are mixed and stirred to generate fine bubbles of the gas in the liquid fuel, and then blown into the storage tank, and the storage tank And a reformed fuel supply means for extracting the stored reformed fuel and supplying it to the combustion apparatus.
　本発明によれば、ノズルによって貯留槽の上部に滞留する気体（運転開始後しばらくするとミスト状の燃料も含まれる）と液体燃料とを混合撹拌して液体燃料中に気体の微細気泡を生じさせた後前記貯留槽に吹き込むため、気液分離器やエアフィルタが不要となり、製造コストを低減することができる。また、ミスト状の燃料が外部に漏出するおそれもなく、改質燃料を燃焼装置に安定して効率よく供給することができる。 According to the present invention, gas stagnating in the upper part of the storage tank by the nozzle (including mist-like fuel after a while after the operation is started) and liquid fuel are mixed and stirred to generate fine gas bubbles in the liquid fuel. After that, since it is blown into the storage tank, a gas-liquid separator and an air filter become unnecessary, and the manufacturing cost can be reduced. Further, there is no fear that the mist-like fuel leaks to the outside, and the reformed fuel can be stably and efficiently supplied to the combustion device.
　上記燃料改質装置において、前記貯留槽内に貯留される燃料を前記ポンプの入口側へ搬送する循環路を設けることができる。貯留槽内に貯留される改質燃料中の微細気泡の濃度は時間の経過によって低減する。そこで、微細気泡の濃度が低減した燃料を循環路を介してポンプへ戻し、再度気体と共にノズルを介して貯留槽に吹き込むことで改質燃料中の微細気泡の濃度を高めることができる。 In the fuel reformer, a circulation path for conveying the fuel stored in the storage tank to the inlet side of the pump can be provided. The concentration of fine bubbles in the reformed fuel stored in the storage tank decreases with time. Therefore, the concentration of the fine bubbles in the reformed fuel can be increased by returning the fuel in which the concentration of the fine bubbles is reduced to the pump through the circulation path and blowing it again into the storage tank through the nozzle together with the gas.
