Description

本発明は、例えば、天ぷら油、エンジンオイル等の廃油を主燃料として燃焼させる廃油ストーブに関する。 The present invention relates to a waste oil stove that burns waste oil such as tempura oil and engine oil as a main fuel.

近年、産業廃棄物に対する規制が強化されており、牛脂などの動物性、大豆油などの植物性又は潤滑油、絶縁油、エンジンオイル等の鉱物性の廃油を処分するのに処理費用が必要になってきている。そこで、廃油をボイラやストーブなどの燃焼装置の燃料として利用することが考えられている（例えば、特許文献１参照。）。 In recent years, regulations on industrial waste have been strengthened, and processing costs are required to dispose of animal waste such as beef tallow, vegetable oil such as soybean oil, or mineral waste oil such as lubricating oil, insulating oil, and engine oil. It has become to. Therefore, it is considered to use waste oil as fuel for a combustion apparatus such as a boiler or a stove (for example, see Patent Document 1).

続いて、上述のような構成をした廃油ストーブ１の燃焼方法について説明する。 Then, the combustion method of the waste oil stove 1 comprised as mentioned above is demonstrated.

着火時には、廃油ストーブ１は、注ぎ口５１から、第１の燃焼室部材１０内部が廃油のみで燃焼できる温度になるだけの少量の灯油が注がれる。次に、空気供給部６０は、空気ノズル６３を介して、第１の燃焼室部材１０内部に空気を供給する。次に、廃油供給部４０は、その廃油流量調整バルブ４７ｂを調整し、第１の燃焼室部材１０内部に廃油を少量供給する。次に、第１の燃焼室部材１０内部に供給された廃油及び灯油は、着火孔２４及び着火孔１８を介して着火される。着火直後は、空気ノズル６３からの空気によって廃油ノズル４９からの廃油と灯油ノズル５３からの灯油を第１の燃焼室部材１０内部に供給する。第１の燃焼室部材１０内部の温度が廃油のみで燃焼が可能になり、灯油供給部５０からの灯油がなくなると、灯油供給部５０の注ぎ口５１から空気が導入される。また、火力調節は、廃油流量調整バルブ４７ｂ及び負圧調節レバー４９ａを操作して、適切な火力にすることができる。 At the time of ignition, a small amount of kerosene is poured into the waste oil stove 1 from the spout 51 so as to reach a temperature at which the inside of the first combustion chamber member 10 can be burned only with waste oil. Next, the air supply unit 60 supplies air into the first combustion chamber member 10 through the air nozzle 63. Next, the waste oil supply unit 40 adjusts the waste oil flow rate adjustment valve 47 b to supply a small amount of waste oil into the first combustion chamber member 10. Next, the waste oil and kerosene supplied into the first combustion chamber member 10 are ignited via the ignition holes 24 and 18. Immediately after ignition, the waste oil from the waste oil nozzle 49 and the kerosene from the kerosene nozzle 53 are supplied into the first combustion chamber member 10 by the air from the air nozzle 63. When the temperature inside the first combustion chamber member 10 can be burned only with waste oil and the kerosene from the kerosene supply unit 50 is exhausted, air is introduced from the spout 51 of the kerosene supply unit 50. In addition, the thermal power can be adjusted to an appropriate thermal power by operating the waste oil flow rate adjusting valve 47b and the negative pressure adjusting lever 49a.

通常運転時には、廃油ノズル４９から供給された廃油は、空気ノズル６３からの空気によって、第１の燃焼室部材１０の中央を上昇し、パンチングプレート１３に付着する。付着した廃油は、燃焼熱で気化する。気化した廃油は、第１の燃焼室部材１０の上部において、空気ノズル６３からの空気によって第１の燃焼室部材１０の胴回り部１０ａの内周部に広がり、対流制御板１１によって、胴回り部１０ａの内周部に沿って、上部から下部に向かってらせん状に対流しながら燃焼する。燃焼した廃油は、図３中の矢印Ａに示すように、上部噴出孔１７ａ及び下部噴出孔１７ｂから第１の燃焼室部材１０の外部に噴出する。第１の燃焼室部材１０内部から噴出した炎は、図１中の矢印Ｂのように、放熱部材３０へと上昇する。その際、第１の燃焼室部材１０から噴出した炎は、燃焼制御板１２に遮られて、外部エア導入孔２５からの空気と炎の中に含まれる燃え残った廃油とが混合され、完全燃焼する。燃焼により発生する熱は、放熱部材３０において放熱される。従って、ユーザは、特段の操作を要せずに、安定して廃油の燃焼が行われる。 During normal operation, the waste oil supplied from the waste oil nozzle 49 rises in the center of the first combustion chamber member 10 by the air from the air nozzle 63 and adheres to the punching plate 13. The adhering waste oil is vaporized by combustion heat. The vaporized waste oil spreads on the inner periphery of the waist portion 10a of the first combustion chamber member 10 by the air from the air nozzle 63 in the upper part of the first combustion chamber member 10, and the waist portion 10a by the convection control plate 11. It burns along the inner periphery of the tube while spirally convection from the top to the bottom. The burned waste oil is ejected to the outside of the first combustion chamber member 10 from the upper ejection hole 17a and the lower ejection hole 17b, as indicated by an arrow A in FIG. The flame ejected from the inside of the first combustion chamber member 10 rises to the heat radiating member 30 as indicated by an arrow B in FIG. At that time, the flame ejected from the first combustion chamber member 10 is blocked by the combustion control plate 12, and the air from the external air introduction hole 25 and the unburned waste oil contained in the flame are mixed together. Burn. Heat generated by the combustion is radiated in the heat radiating member 30. Therefore, the user can stably burn the waste oil without requiring any special operation.

消火時には、ユーザは、廃油コック４７ｃを閉じて、廃油の供給を停止させることで、燃焼は停止する。消火確認後、ユーザは、空気供給部５０を停止させることで、運転を終了する。 At the time of fire extinguishing, the user closes the waste oil cock 47c and stops the supply of the waste oil, thereby stopping the combustion. After confirming that the fire has been extinguished, the user stops the operation by stopping the air supply unit 50.

また、メンテナンス時には、ユーザは、固定部材１９をはずすことによって、廃油ストーブ１を放熱部材３０、第２の燃焼室部材２０、第１の燃焼室部材１４に分割することができ、内部壁面に付着したカーボンスラッジ等の汚れを落とすことが容易になる。 Further, during maintenance, the user can divide the waste oil stove 1 into the heat dissipating member 30, the second combustion chamber member 20, and the first combustion chamber member 14 by removing the fixing member 19, and adhere to the inner wall surface. It becomes easy to remove dirt such as carbon sludge.

以上のように構成された廃油ストーブ１は、廃油を主燃料としているので、廃油を効率よく処理することができる。また、空気供給部６０は、廃油の霧化に必要な低圧で足りるため、経済的である。 Since the waste oil stove 1 configured as described above uses waste oil as a main fuel, the waste oil can be efficiently processed. Further, the air supply unit 60 is economical because it requires a low pressure necessary for atomizing the waste oil.

また、第１の燃焼室部材１０は、気化した廃油及び灯油を第１の燃焼室部材１０内部を第１の燃焼室部材１０の上部から下部に向かってらせん状に対流させる複数の対流制御板１１と、第１の燃焼室部材１０の外部で胴回り部１０ａの内部に外部エア導入孔２５より取り込んだ空気と燃え残った廃油及び灯油とを混合させ燃焼する燃焼制御板１２とが設けられているので、燃料を完全に燃焼させることができ、煙がない。また、廃油は、廃油ノズル４９を介して第１の燃焼室部材１０内部に供給され、空気ノズル６３からの空気によって噴霧され、対流制御板１１により、第１の燃焼室部材１０内部を対流させているので、カーボンスラッジ等の付着が少なく、また付着したカーボンスラッジも柔らかいものになる。 Further, the first combustion chamber member 10 includes a plurality of convection control plates that convect the vaporized waste oil and kerosene in a spiral manner from the upper portion of the first combustion chamber member 10 toward the lower portion of the first combustion chamber member 10. 11 and a combustion control plate 12 for mixing and burning the air taken in from the external air introduction hole 25 and the unburned waste oil and kerosene outside the first combustion chamber member 10 inside the waist portion 10a. As a result, the fuel can be burned completely and there is no smoke. The waste oil is supplied into the first combustion chamber member 10 through the waste oil nozzle 49 and sprayed by the air from the air nozzle 63, and the convection control plate 11 convects the first combustion chamber member 10. Therefore, there is little adhesion of carbon sludge etc., and the adhered carbon sludge becomes soft.

さらに、第２の燃焼室部材２０と放熱部材３０と第１の燃焼室部材１０とは、固定部材１９により固定されており、分解が容易で、メンテナンスも楽な廃油ストーブである。 Further, the second combustion chamber member 20, the heat radiating member 30, and the first combustion chamber member 10 are fixed by a fixing member 19, and are a waste oil stove that is easy to disassemble and easy to maintain.
