本発明は、燃料油、特にディーゼル機関に使用される品
質の粗悪な燃料油を処理して、品質を向上させ機関運転
に支障なからしむることを目的とする。[Detailed Description of the Invention] 3. Detailed Description of the Invention The present invention is a method for treating fuel oil, particularly poor-quality fuel oil used in diesel engines, to improve its quality and to prevent it from interfering with engine operation. The purpose is to
従来、ディーゼル機関に使用された燃料油は２５０セン
チストークス（５０℃）以下の良品質のものであって、
加熱後ディスク型遠心清浄機で油中に含まれている水分
、固形物等の不純物を分取した清浄な油を機関内に供給
して順調に燃焼されていた。Conventionally, the fuel oil used in diesel engines is of good quality with a temperature of 250 centistokes (50°C) or less,
After heating, a disk-type centrifugal cleaner was used to remove impurities such as moisture and solids from the oil, and the clean oil was then fed into the engine, where it was combusted smoothly.
しかしながら、２５０センチストークス（５０”Ｃ）以
下の油であっても、ディスク型遠心清浄機は、ディスク
間の間隙が極めて狭い構造上の特性から、処理運転の初
期から次第にディスクの間隙に固形物の堆積が始まる。However, even with oil of 250 centistokes (50"C) or less, disk-type centrifugal cleaners are structurally characterized by extremely narrow gaps between the disks, so solids gradually accumulate in the gaps between the disks from the beginning of processing operation. begins to accumulate.
比重の重い固形物は、回転筒から連続的に、あるいは、
間歇的に排出されてわいろが、１５〜３０日間連続運転
すると運転を停止し、分解掃除しなければならない状態
となる。この分解掃除は人力で行５ので、省力化の進ん
だ今日では機関員の大きな負担となっている。Solids with heavy specific gravity are transported continuously from a rotating cylinder or
The bribe is discharged intermittently, but after 15 to 30 days of continuous operation, the system must be stopped and disassembled for cleaning. This disassembly and cleaning is done manually5, which is a heavy burden on the engine staff in today's age of labor-saving technology.
更に、最近は２５０センチストークス（５０°Ｃ）以下
の油とわ言っても、均一な品質の油で構成されているも
のではなく、低粘度の油と高粘度の油を混合して、他の
物性に係りな（粘度だけを調製した油が多くなり、比重

ムを交換する必要から、その都度機械の停止を行わねば
ならず、時にはリング・ダムの比重調整の限界を越え、
処理不能となるような極端な場合も発生する。Furthermore, even though oil is said to be 250 centistokes (50°C) or less these days, it is not composed of oils of uniform quality, but rather is made up of a mixture of low viscosity oil and high viscosity oil, and other oils. Regarding the physical properties of oil (only the viscosity has been adjusted), there is a large amount of oil, and the specific gravity is not constant.As a result, it is necessary to replace the ring tom of the de-isk type separator, and the machine must be stopped each time. Sometimes exceeding the limits of specific gravity adjustment of ring dams,
Extreme cases may occur where processing becomes impossible.
また、上記のような混合された油は、船舶に貯油されて
いる間に、低比重の７スフアルテンが生成され、油部分
と共に分離されて機関入口に導入され、この入口に設置
されている目の細いストレーナ−の目を詰めるので、頻
繁に掃除を行う必要に迫られる。In addition, while the above-mentioned mixed oil is stored on a ship, 7-sulfaltenes with low specific gravity are generated, separated along with the oil part, and introduced into the engine inlet, which is then introduced into the engine inlet. Because the eyes of the thin strainer become clogged, it is necessary to clean it frequently.
更に、近来船舶よりの排水忙対し、国際的に厳しい規制
が定められるようになり、高比重の未処理油より分離さ
れて出て来る排水には、近来増加傾向の油中に含まれた
不純物と乳化した水が多（なり、規制の基準値に合わせ
るための後処理に特別の処理装置を設備しなければなら
ぬこととなった。Furthermore, with the recent increase in wastewater discharge from ships, strict regulations have been established internationally, and the wastewater that is separated from high-density untreated oil is subject to impurities contained in the oil, which has been increasing in recent years. This resulted in a large amount of emulsified water, necessitating the installation of special treatment equipment for post-treatment to meet regulatory standards.
以上のように、昔日の高品質の均一な燃料油と異なり、
昨今では劣悪な油を使用する結果、種々の処置すべき問
題点が生じているのである。As mentioned above, unlike the high quality uniform fuel oil of the past,
Nowadays, the use of inferior oils has resulted in various problems that need to be addressed.
今後は、原油の重質化、および軽質油回収率増大主義の
石油精製法が取られていることに依って燃料油の低質化
が益々進み、比重が１．００（１５／４°Ｃ）を越える
７００センチ・ストークス（５０℃）以上の粘度を有す
る燃料油の供給も予想される。In the future, as crude oil becomes heavier and petroleum refining methods are adopted that emphasize increasing light oil recovery, the quality of fuel oil will continue to decline, with a specific gravity of 1.00 (15/4°C). The supply of fuel oils with viscosities in excess of 700 centiStokes (50° C.) is also anticipated.
このような燃料油を従来法で処理すれば、上述の問題点
に加えて、ディスク型遠心分離機の回転筒の封水が不可
能となり、多量の燃料油損失が見込まれる。If such fuel oil is treated by the conventional method, in addition to the above-mentioned problems, it becomes impossible to seal the rotating tube of the disk centrifuge, and a large amount of fuel oil is expected to be lost.
従って、省力化による小人数でも不安なく、安全な航行
ができるような燃料油の清浄装置が求められており、本
発明は、この要求を満すものである。Therefore, there is a need for a fuel oil purifying device that saves labor and allows even a small number of people to sail safely without anxiety, and the present invention satisfies this need.
本出願人は、昭和５４年特許願第２９９８６号において
、「舶用燃料油の処理方法」について述べているが、本
発明はその後における処理燃料油の品質が一段と更に低
下していることに対応して、この「方法」を更に改良し
た装置を提供するものである。In Patent Application No. 29986 filed in 1972, the present applicant has described a "method for treating marine fuel oil," but the present invention addresses the further deterioration in the quality of treated fuel oil. Therefore, we provide an apparatus that further improves this "method".
以下、図面にもとづき、本発明の詳細につき述べる。The details of the present invention will be described below based on the drawings.
本発明の構成に不可欠のものは、ヒーター５と改良され
たデカンタ−型遠心分離機と遠心フィルター１５を配設
することである。Essential to the configuration of the present invention is the provision of a heater 5, an improved decanter type centrifuge, and a centrifugal filter 15.
第６図に実施例を示し、この燃料油清浄装置による清浄
の作用工程を詳細に説明する。An example is shown in FIG. 6, and the cleaning process by this fuel oil cleaning device will be explained in detail.
前述のように品質の低下した燃料油は、第３図に示すよ

。The fuel oil whose quality has deteriorated as described above is transferred from the fuel tank 1 to the settling tank 3 by the pump 2 as shown in FIG.
The fuel oil is put into a heater 5 by a pump 4 and reheated to 80 to 100°C to lower the viscosity and specific gravity and improve the settling properties of water and sludge particles in the fuel oil, and then heated to an improved decanter.
type centrifuge 11. Moisture and relatively large sludge are separated and removed by the separator 11 under a large centrifugal force, and the purified oil is transferred to the storage tank 12.
and is supplied to a centrifugal filter 15 by a pump 14.

た。The oil supplied to the centrifugal filter 15 is re-cleaned of fine sludge and cut of asphaltene by a special element inside the filter that rotates at high speed, so that its properties become stable and the oil is homogenized, drawn, diameter-serviced, etc. It was sent to tank 8 and supplied to the diesel main engine via a pump.

主機入口のストレーナ−の目詰りも大巾に改善されるこ
とが確認された。In the conventional method shown in Figure 1 and the improved method shown in Figure 2, if the disk type centrifuge becomes clogged, the strainer at the main engine inlet will become clogged, which will hinder ship navigation. According to the present invention, even when using fuel oil having centistokes (50°C) properties, since a disc centrifuge is not used, there is no need to worry about clogging of the disc (9).
It was confirmed that clogging of the strainer at the main engine inlet was also significantly improved.
従って、本発明によれば、粘度１８０センチストークス
（５０℃）以下の性状を有する燃料油はもとより、４５
０センチストークス（５０°Ｃ）程度の低品質の燃料油

で、デ・イーゼル主機の船舶に使用すれば、港に依り、
受入燃料油の性状が異る場合にも、安心して航行の安全
が保障され、省力化の面でも多大の効果がある。Therefore, according to the present invention, not only fuel oil having a viscosity of 180 centistokes (50°C) or less, but also fuel oil having a viscosity of 45 centistokes or less
Even with low-quality fuel oil of around 0 centistokes (50°C), continuous cleaning operation can be performed over a wide range, so if it is used on a ship with a de-easel main engine, it can be cleaned depending on the port.
Even when the properties of the received fuel oil are different, safe navigation is guaranteed and there is a great effect in terms of labor savings.
また、本発明によれば、ディスク型遠心分離機を必要と
しないので、その保守、省力、設計、経済の面でも優れ
た効果がある。Further, according to the present invention, since a disk type centrifuge is not required, there are excellent effects in terms of maintenance, labor saving, design, and economy.
