この発明は、廃油タンク内の廃油からの水分除去方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for removing water from waste oil in a waste oil tank.
従来、例えば、船舶内において生じる廃油は、廃油タン
クに一旦溜められ、その後、燃焼させて処理するが、廃
油内に水分が多量に含まれているので、この水分を除去
するために第２図に示すように、廃油タンクｌ内に蒸気
配管２を設け、加熱蒸気によって廃油を加熱して廃油中
の水分を蒸発させている。Conventionally, for example, waste oil generated on board a ship is temporarily stored in a waste oil tank and then burned to be disposed of.However, since the waste oil contains a large amount of water, in order to remove this water, a method is used to remove this water. As shown in the figure, a steam pipe 2 is provided in a waste oil tank 1, and the waste oil is heated by heated steam to evaporate water in the waste oil.
しかし、上述した水分蒸発方法は、以下の問題点を有し
ている。即ち、蒸気を長時間使用するので、多量のエネ
ルギーを要し、廃油の加熱は自然対流によるために加熱
効率が悪く、さらに、廃油タンク１に設けられている空
気抜き管３内の蒸気の流速が遅いので、−度蒸発した水
分が空気抜き管３内で復水して廃油タンク１に逆流する
。However, the above-described water evaporation method has the following problems. That is, since steam is used for a long time, a large amount of energy is required, and the heating efficiency of the waste oil is poor because it is heated by natural convection.Furthermore, the flow rate of the steam in the air vent pipe 3 provided in the waste oil tank 1 is Since it is slow, the evaporated water condenses in the air vent pipe 3 and flows back into the waste oil tank 1.
この発明は、廃油タンク内の底部に、被数個のノズルを
有するヘッダ管を設け、前記ヘッダ管に、内燃機関の過
給機出口からの高温高圧掃気用空気の一部を供給して、
前記廃油タンク内の廃油を加熱することに特徴を有する
ものである。This invention provides a header pipe having several nozzles at the bottom of a waste oil tank, and supplies a portion of high-temperature, high-pressure scavenging air from a supercharger outlet of an internal combustion engine to the header pipe,
The present invention is characterized in that the waste oil in the waste oil tank is heated.
次に、この発明の、廃油タンク内の廃油からの水分除去
方法の一実施態様を図面を参照しながら説明する。Next, an embodiment of the method for removing water from waste oil in a waste oil tank according to the present invention will be described with reference to the drawings.
第１図は、この発明の、廃油タンク内の廃油からの水分
除去方法の一実施態様を示す概略構成図である。FIG. 1 is a schematic diagram showing an embodiment of the method for removing water from waste oil in a waste oil tank according to the present invention.
第１図に示すように、この発明は、船舶内の廃油タンク
１内の底部に、複数個のノズル４を有するヘッダ管５を
設け、ヘッダ管５に、主機関６の過給機７の出ロアＡか
らの高温高圧の掃気用空気の一部を供給するものである
。過給機７からの残りの高温高圧の掃気用空気は、従来
と同様に空気冷却器８と掃気マニホールド９を経て、主
機関６に供給される。As shown in FIG. 1, the present invention provides a header pipe 5 having a plurality of nozzles 4 at the bottom of a waste oil tank 1 in a ship, and a supercharger 7 of a main engine 6 is connected to the header pipe 5. It supplies a portion of the high-temperature, high-pressure scavenging air from the outlet lower A. The remaining high-temperature, high-pressure scavenging air from the supercharger 7 is supplied to the main engine 6 via an air cooler 8 and a scavenging manifold 9, as in the conventional case.
廃油タンク１内に掃気空気が噴射されると、廃油タンク
１内の廃油は、掃気空気の保有する熱によって加熱され
て、廃油中に含まれる水分が蒸気化する。廃油は、掃気
空気によって攪拌されるので、廃油は効率良く加熱され
る。廃油タンク１内の蒸気は、廃油タンク１の頂部に接
続された空気抜き管３から大気に放出される。When the scavenging air is injected into the waste oil tank 1, the waste oil in the waste oil tank 1 is heated by the heat held by the scavenging air, and the water contained in the waste oil is vaporized. Since the waste oil is agitated by the scavenging air, the waste oil is efficiently heated. Steam in the waste oil tank 1 is released to the atmosphere from an air vent pipe 3 connected to the top of the waste oil tank 1.

流速が速まり、この結果、空気抜き管内で蒸気が復水す
る虞れは皆無である等、種々の有用な効果がもたらされ
る。As explained above, according to the present invention, the waste oil in the waste oil tank is heated while being stirred by the excess high temperature and high pressure scavenging air from the supercharger, so that energy can be saved and the waste oil can be heated efficiently. Moreover, since scavenging air is supplied into the waste oil tank, the flow rate of steam in the air vent pipe increases, and as a result, there is no risk of steam condensation in the air vent pipe, and various other useful effects are achieved. brought about.
