がある。 A conventional fuel oil system is shown in FIG. That is, the fuel oil in the fuel oil tank 2, which is heated by the heating coil 1, is taken out by the fuel oil pump 3 into the settling tank 4, where it is heated by the heating coil 5. Then, the fuel oil in the settling tank 4 is supplied to a cleaner fuel oil heater 8 by a cleaner fuel oil supply pump 7 driven by a drive motor 6, where 95~
Heated to 98℃. The heated fuel oil is sent to the fuel oil cleaner 9 and cleaned. Cleaned 90
Fuel oil at ~95°C is supplied to a service tank 11 by a clean fuel oil delivery pump 10. The amount of fuel supplied at this time is greater than the amount consumed by the main engine 12, so excess fuel oil is returned to the settling tank 4 via the overflow pipe 13. 14 indicates an air vent pipe. The fuel oil in the service tank 10 is heated and kept warm by the heating coil 15, but the oil temperature in the service tank 11 is equal to or higher than the flash point (approximately 60°C) of the fuel oil even after deducting heat radiation, that is, 80°C. Temperatures reach ~85℃ and vapor is generated, which is dangerous. In addition, since the fuel oil purifier 9 passes excess fuel oil in excess of the amount consumed by the main engine 12, its cleaning effect is reduced, and since the purified fuel oil is temporarily stored in the service tank 11, heat radiation It tends to deteriorate when cooled. The fuel oil in the service tank 11 is supplied to the main engine fuel oil supply pump 1.
6 to the main engine fuel oil heater 17, where it is heated to 130 to 150°C and then supplied to the main engine 12. The surplus fuel oil from the main engine 12 is returned to the vapor separator 18, and the fuel oil separated from vapor here is circulated again by the main engine fuel oil supply pump 16. By the way, the excess fuel oil discharged from the main engine 12 has a considerably high temperature (100~
(approximately 140℃), and a large amount of vapor is generated as it is exposed to atmospheric pressure. The vapor separator 18 separates vapor from fuel oil, but if a large amount of vapor is generated, vapor containing a large amount of oil mist will be released into the atmosphere from the air vent pipe 19, which can be dangerous. Also, since the high temperature fuel oil separated from the vapor by the vapor separator 18 returns to the suction side of the main engine fuel oil supply pump 16, the vapor is removed from the suction side of the main engine fuel oil supply pump 16 and the fuel valve of the main engine 12. may occur, making it impossible to supply the desired fuel oil.

発生を極減することができる。 The present invention provides a fuel oil purifier that communicates with the settling tank, and supplies the fuel oil treated by the fuel oil purifier directly to the suction side of the fuel oil supply pump for the main engine, and connects the fuel oil purifier to the main engine. A service tank is connected between the fuel oil supply pump and an oil level detector is installed in this service tank, and the amount of oil flowing to the fuel oil purifier is determined based on the oil level detection signal from this oil level detector. The present invention provides a fuel oil treatment and supply device for a diesel engine, which is configured to control the fuel oil, has a fuel oil return path from the main engine opened in the service tank, and has a cooling device interposed in the fuel oil return path. . According to this configuration, the oil passage through the fuel oil cleaner can be reduced to the minimum required amount (fuel oil consumption of the main engine), and the cleaning effect of the fuel oil cleaner can be enhanced. In addition, by supplying clean fuel oil directly to the main engine, in other words, by using the service tank as a buffer tank,
It is possible to prevent an abnormal rise in oil temperature (for example, above the flash point) in the service tank. Furthermore, since the fuel oil can be sufficiently cooled by the cooling device during the fuel oil return path and is returned to the fuel oil in the service tank, the generation of vapor can be minimized.

Note that the same reference numerals as in the conventional example (FIG. 1) indicate the same or almost the same components. Namely, 1 is a heating coil, 2 is a fuel oil tank, 3 is a fuel oil pump, 4 is a settling tank, 5 is a heating coil, 6 is a drive motor, 7 is a fuel oil supply pump for the cleaner, and 8 is the fuel for the cleaner. 9 is a fuel oil purifier, 10 is a clean fuel oil discharge pump, 11 is a service tank, 12 is a main engine (diesel engine),
14 is an air vent pipe, 15 is a heating coil, 16 is a fuel oil supply pump for the main engine, 17 is a fuel oil heater for the main engine, 18 is a vapor separator, and 19 is an air vent pipe. In the present invention, the fuel oil treated by the fuel oil purifier 9 is directly supplied to the suction side of the main engine fuel oil supply pump 16 via the check valve 20.
And check valve 20 and main engine fuel oil supply pump 16
A service tank 11 is communicated between the two. This service tank 11 is provided with an oil level detector (hydraulic controller) 21.
The fuel oil purifier 9 is activated by the oil level detection signal 22 from the
This oil level detection signal 22 is used to control the amount of oil flowing to the
The drive motor 6 is controlled by. That is, while keeping the oil temperature in the service tank 11 below the flash point, the fuel oil purifier 9
In order to improve the cleaning effect of the fuel oil purifier 9, the fuel oil coming out of the fuel oil purifier 9 is not put into the service tank 11, but is directly supplied to the main engine fuel oil supply pump 16, and the service tank 11 is used to prevent the unbalance of the fuel oil amount. It is used as a buffer tank that absorbs water. And fuel oil heater 8 for purifier and fuel oil purifier 9
The amount of oil flowing to is determined by controlling the rotation speed of the drive motor 6 based on the oil level detection signal 22 from the oil pressure detector 21.
Only the amount of fuel oil consumed by the main engine 12 is allowed to flow. According to this, the fuel oil in the service tank 11 is in a storage state with almost no going in or out, so it never exceeds the flash point. Further, since the amount of oil passed through the fuel oil cleaner 9 is the minimum required amount (the amount consumed by the main engine), there is no need to dispose of excess fuel oil, and the cleaning effect of the fuel oil cleaner 9 is enhanced.
That is, the fuel oil purifier 9 is generally a centrifugal oil purifier, and has the performance that the smaller the amount of oil passed, the higher the cleaning effect. A hydraulic pressure control valve 23 is provided in the fuel oil return path from the main engine 12 to increase the fuel oil pressure between the main engine fuel oil supply pump 16 and the hydraulic pressure control valve 23. This is intended to prevent vapor lock in the fuel oil pump of the main engine 12. Furthermore, an oil cooler 24 is provided above the oil pressure control valve 23 to cool the return fuel oil and lower the oil temperature at the inlet of the main engine fuel oil supply pump 16. Prevent vapor lock. Further, the vapor separated by the vapor separator 18 is condensed in a vapor condenser 26 provided in the middle of an air vent pipe 25, and the outlet of the air vent pipe 25 is placed below the oil level of the service tank 11. In this way, the fuel oil vapor is prevented from escaping into the atmosphere by completely returning the vapor to oil using the low-temperature oil in the service tank 11. The oil cooler 24 and vapor condenser 26 described above constitute a cooling device.

料油の使用に対処できることになる。 According to the present invention described above, by controlling the amount of oil flowing to the fuel oil purifier based on the oil level detection signal and keeping the oil level in the service tank constant, the amount of oil flowing through the fuel oil purifier is minimized. The amount of fuel oil consumed by the main engine can be kept to the necessary limit (the amount of fuel oil consumed by the main engine), and the cleaning effect of the fuel oil cleaner can be enhanced. Further, by supplying clean fuel oil directly to the main engine, that is, by using the service tank as a buffer tank, it is possible to prevent the oil temperature from rising abnormally (for example, above the flash point) in the service tank. Furthermore, since the fuel oil can be sufficiently cooled by the cooling device during the fuel oil return path and is returned to the fuel oil in the service tank, the generation of vapor can be minimized. This allows the oil temperature from the service tank side to be kept low, preventing vapor from occurring on the suction side of the main engine fuel oil pump or the main engine fuel valve, thereby ensuring the safe supply of fuel oil. , can be carried out smoothly and reliably. These considerations make it possible to cope with the recent use of low quality fuel oil.
