EXAMPLE

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are flowcharts of one embodiment of a fuel oil feed apparatus according to the present invention, respectively.

In FIG. 1, reference numeral 7 denotes a fuel oil storage tank, and a vessel or the like usually stores high viscosity fuel oil such as heavy oil C. The fuel oil storage tank 7 communicates with the fuel oil removal tank 2 through the transfer pipe 14 provided in the transfer pump 3, and is equipped with a heating device not shown in the drawing.

The fuel oil cleansing tank 2 is furthermore connected to the fuel oil service tank 1 (fuel oil) through the connector 16 and through the heater 17 and the fuel oil cleaner 18 disposed in the connector 16. Communication tank). Furthermore, the fuel oil cleaning tank 2 and / or fuel oil service tank 1 are in communication with the fuel oil storage tank 7 through the valves 9, 10 and the suction pipe 13 together. The suction pipe 13 is provided with a flow pump 14. (11) and (12) are valves.

The present invention is characterized in that in the above-described configuration, the heater 8 is installed in the suction pipe 13, the temperature sensor 6 is installed in the transfer pipe 14, and further, the flow pump 4 installed in the suction pipe 13 and The heater 8 and the temperature sensor 6 and the transfer pump 3 provided in the transfer pipe 14 are connected to the controller 5, respectively.

The heater 8 is provided in any part of the suction pipe 13, but in order to avoid passage of the fuel oil heated by the heater 8 into the dripping pump 4, that is, downstream of the dripping pump 4, namely The suction pipe 13 on the outlet side of the flow pump 4 is preferably installed.

Furthermore, the above-described temperature sensor 6 is also provided in any part of the transfer pipe 14, but the direction downstream of the transfer pump 3, that is, the outlet side of the transfer pump 3, is in the direction of the fuel oil storage tank 7. It is good because the fuel oil temperature can be measured more correctly because it is farther away.

From the above configuration, the fuel oil transfer apparatus according to the present invention operates as follows and exhibits the operation of the present invention.

First, the transfer pump 3 is moved to transfer fuel oil from the fuel oil storage tank 7 to the fuel oil cleaning tank 2 through the transfer pipe 14. Subsequently, the fuel oil conveyed in the fuel oil removal tank 2 exits through the connecting pipe 16 after heating, and is reheated by the heater 17 disposed in the connecting pipe 16 and at the same time, the connecting pipe ( It is cleaned by the fuel oil cleaner 18 disposed in 16 and sent to the fuel oil service tank 1. In this way, the fuel oil cleaning tank 2 and the fuel oil service tank 1 are filled with heated fuel oil.

The heated fuel oil is supplied to the valves 9 and 10 by the movement of the lower pump 4 (variable flow pump) from at least one or both directions of the fuel oil cleaning tank 2 and the fuel oil service tank 1. It is reheated by the heater (8) through the suction pipe (13) and sent to the transfer pipe (14), and returned to the fuel oil storage tank (7) through the valves (11) and (12) to mix the fuel oil therein. Heat. At the same time, the fuel oil in the fuel oil service tank 1 is distributed and supplied to the main machine 19, the bogie 20, the boiler 21, and the like.

When the fuel oil in the fuel oil storage tank 7 is transferred to the fuel oil removal tank 2 by the transfer pump 3 through the transfer pipe 14, 3 to 5 minutes after starting the transfer pump 3. Then, the temperature sensor 6 detects the temperature of the fuel oil mixed and heated in the fuel oil storage tank 7. Based on the detected temperature, it is judged whether or not the heating fuel flow rate (heat amount) flowing down through the suction pipe 13 is appropriate, and the flow rate or temperature is adjusted. That is, in order to make it necessary heat amount, the flow volume may be increased or decreased, and temperature needs to be raised and lowered. Or decide which of these should take precedence. For example, when the capacity of the transfer pump 3 is small, the heater 8 is preferentially controlled. Also. When either the capacity of the transfer pump 3 or the capacity of the heater 8 is large, both can be changed simultaneously.

In order to transfer C heavy oil through the conveyance pipe 14, the viscosity must be 1000 cst or less. The set temperature to be set in the controller 5 is set to + 2 ° C of the temperature of this transferable viscosity of 100 sct, and this temperature is set in advance in the controller 5. For example, in the case of C heavy oil having a viscosity of 380 cst (50 ° C.), the temperature is set at a temperature of 35 ° C. + 2 ° C., that is, 37 ° C. with a viscosity of 1000 cst.

Further, according to the above, first, prior to the operation of the apparatus of the present invention, since the fuel oil is already filled in the transfer pipe 14, the fuel remaining in the transfer pipe 14 is operated by operating the transfer pump 3 for about 5 minutes. The oil is transferred to the fuel oil cleaning tank (2). This five-minute time is set by the timer by installing a timer in the transfer pump 3.

In this way, the fuel oil remaining in the transfer pipe 14 is moved, and then the fuel pump 4 is continuously operated to transfer the fuel oil heated in the fuel oil cleaning tank 2 to the fuel oil service tank 1. At the same time, the fuel oil storage tank (7) is either one or both of the fuel oil cleaning tank (2) and the fuel oil service tank (1) through the valves (9) and (10), and the suction pipe (13). It flows down into the internal fuel oil, and it mixes with the fuel oil of this, and heats.

Although the normal speed change pump is used as the flow pump 4, the flow rate is adjusted by providing the bypass valve 15 as shown in FIG. That is, the opening and closing degree of the bypass valve 15 is adjusted by a controller, and the flow volume which flows into a bypass is controlled. Opening the bypass valve 15 large increases the flow rate, while opening the bypass valve 15 decreases the flow rate.

In this case, the variable speed pump is not necessary and flow control is performed as a normal pump.

Fuel oil in the heated fuel oil storage tank 7 is transferred to the fuel oil cleansing tank 2 through the transfer pipe 14 by the operation of the transfer pump 3. The fuel oil temperature at this time is measured by the temperature sensor 6 and is in contact with the controller 5.

In the controller 5, the measured temperature at the temperature sensor 6 and the fuel oil in the fuel oil storage tank 7 preset in the controller 5 are transferred to the fuel oil cleaning tank 2 through the transfer pipe 14. The difference between the optimum temperature and the temperature obtained is read and understood, and this information is sent to the lower pump 4, the heater 8, and the transfer pump 3, respectively, and operated by the control of the controller 5 to correct the difference. Correct it.

Although the controller 5 is not shown in figure, the optimum temperature setting part A, the temperature information detection part B from the temperature sensor 6, the flow rate control part C of the flow pump 4, and the temperature of the heater 8 are shown. The control unit D is provided with the priority setting unit E of the flow pump flow rate control and the heater temperature control.

When the temperature of the temperature sensor 6 sensed by the temperature information detecting unit B is lower than the set temperature of the optimum temperature setting unit A, the flow rate of the flow pump 4 is operated by the operation of the flow rate control unit C. Increase or increase the temperature of the heater 8 by the operation of the temperature control unit D, thereby controlling the detected temperature of the temperature information detecting unit B to be the set temperature of the optimum temperature setting unit A. .

On the contrary, when the temperature of the temperature sensor 6 detected by the temperature information detecting unit B is higher than the set temperature of the optimum temperature setting unit A, the flow pump 4 is operated by the operation of the flow control unit C. The flow rate of the heater 8 is reduced or the temperature of the heater 8 is lowered by the operation of the temperature control unit D so that the detected temperature of the temperature information detecting unit B becomes the set temperature of the optimum temperature setting unit A. do.

The above-mentioned temperature control is performed by focusing both of the flow control unit C and the temperature control unit D on the basis of the priority set in the priority setting unit E.

For example, when the seawater temperature is 13 ° C. and the flow rate of oil from the fuel oil cleaning tank 2 or the fuel oil service tank 1 is appropriate at 3000 L / hr (80 ° C.), that is, the measurement from the temperature sensor 6. When the difference between the temperature and the optimum temperature preset in the controller 5 occurs, the temperature difference occurs because the sea water temperature drops to 8 ° C. To correct this temperature difference, the temperature is increased from the heater 8 to (85 ° C) so that the flow rate does not change, or 3000L / hr (85 ° C) or the flow rate is increased to 4,028.4ℓ / hr (80 ° C) so that the temperature does not change. do.

This selection is made by instructing the controller 5 of the degree of dominance.

As a result, the fuel oil through the transfer pipe 14 is always maintained at the optimum temperature.

As described above, the fuel oil transfer device according to the present invention does not require expensive and complicated equipment such as a boiler and a heating tube when the fuel oil is transferred from the fuel oil storage tank to the fuel oil cleaning tank. It is an extremely advantageous invention in practical use which can be transported at all times while heating to an optimum temperature.
