Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, and specifically relates to an energy-saving fuel release system. Background Technology

[0002] Ships burning heavy fuel oil and diesel fuel typically have fuel spill tanks to collect spilled or leaked fuel oil. These tanks usually contain a mixture of fuel oil and a large amount of water, which is generally not suitable for recycling. It is typically pumped to a sludge tank and then discharged ashore for treatment or incinerated. Treating this waste oil requires significant manpower and resources. Therefore, utilizing this waste fuel oil would have considerable economic and commercial value. Many ships equip themselves with a fuel oil separator to repeatedly separate the fuel oil from the fuel spill tank for reuse. However, the fuel oil separator system consumes initial investment and electricity during multiple separation processes, ultimately failing to achieve the ideal cost-effectiveness. Therefore, most ships simply transfer the waste fuel oil from the fuel spill tank directly to the sludge tank and discard it. In today's era of energy conservation and emission reduction, coupled with rising fuel prices, how to conserve every drop of fuel oil has become an essential issue to consider. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes an energy-saving fuel release system.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: An energy-saving fuel release system includes a fuel release chamber, an oil residue chamber, and a fuel clarification chamber. The fuel release chamber has a first chamber and a second chamber connected at the top, and heating components are installed in both the first chamber and the second chamber. The first chamber is connected to a fuel release main pipe and is connected to the oil residue chamber via an oil residue conveying pipe. The second chamber is connected to the fuel clarification chamber via a fuel conveying pipe. An oil residue pump and a fuel conveying pump are respectively installed on the oil residue conveying pipe and the fuel conveying pipe.

[0005] Furthermore, the inner cavity of the fuel release chamber is divided into the first chamber and the second chamber by a partition. A fuel through hole is provided on the upper part of the partition. The lower edge of the fuel through hole is located at 70% to 80% of the height of the partition from the bottom wall of the fuel release chamber.

[0006] Furthermore, the system also includes a control system, which includes an electrical control box, a moisture detection sensor located in the first chamber, and a high liquid level sensor located in the second chamber. The moisture detection sensor is linked and controlled by the oil sludge pump, the high liquid level sensor, and the fuel delivery pump through the electrical control box. The height difference between the sensing end of the moisture detection sensor and the lower edge of the fuel through hole is not less than 9% of the height of the partition.

[0007] Furthermore, a drain pipe is connected between the oil residue conveying pipe and the fuel oil conveying pipe. A first valve is provided on the drain pipe.

The third valve is located on the side of the drain pipe and the fuel oil conveying pipe near the fuel oil clarification chamber. A moisture detection sensor is provided in the second chamber. The moisture detection sensor is linked to the oil residue pump through the electrical control box for linkage control.

[0008] Furthermore, the control system also includes a low liquid level sensor installed on the first chamber. The installation height of the low liquid level sensor is 20% to 30% of the chamber height and it is located above the suction port of the oil residue conveying pipe. The low liquid level sensor and the oil residue pump are linked and controlled through the electrical control box.

[0009] Furthermore, a low liquid level sensor is provided on the second chamber. The installation height of the low liquid level sensor is 20% to 30% of the chamber height and it is located above the fuel delivery pipe suction port.

[0010] Furthermore, there are multiple fuel passage holes, which are arranged at intervals along a straight line; multiple vent holes are provided on the top surface of the partition, and the multiple vent holes are evenly distributed above the multiple fuel passage holes.

[0011] Furthermore, a depth measuring device is provided in both the first chamber and the second chamber; a vent pipe is provided at the fuel through hole.

[0012] Furthermore, the electrical control box is communicatively connected to the ship's monitoring and alarm system and the ship's automation system.

Detailed Implementation

[0018] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. Any similar structures or variations thereof employing the present invention are within the protection scope of the present invention.

[0019] like Figures 1-2 As shown, an energy-saving fuel release system includes a fuel release chamber 1, an oil residue chamber 2, and a fuel clarification chamber 3. The fuel release chamber 1 has a first chamber 101 and a second chamber 102 connected at the top. Heating components are provided in both the first chamber 101 and the second chamber 102. The first chamber 101 is connected to a fuel release main pipe 4, and the first chamber 101 is connected to the oil residue chamber 2 through an oil residue conveying pipe 5. The second chamber 102 is connected to the fuel clarification chamber 3 through a fuel conveying pipe 6. An oil residue pump 7 and a fuel conveying pump 8 are respectively provided on the oil residue conveying pipe 5 and the fuel conveying pipe 6. In some embodiments, the heating component is a steam heating coil 9, which can be used in each chamber or shared by two chambers.

[0020] Preferably, the inner cavity of the fuel release chamber 1 is divided into a first chamber 101 and a second chamber 102 by a partition 10. A fuel through hole 1001 is provided on the upper part of the partition 10, and the lower edge of the fuel through hole 1001 is at a height of 70% to 80% of the height of the partition 10 from the inner bottom wall of the fuel release chamber 1. In some embodiments, the lower edge of the fuel through hole 1001 is at a height of 75% of the height of the partition 10 from the inner bottom wall of the fuel release chamber 1. There are multiple fuel through holes 1001, which are arranged sequentially at intervals along a straight line. Multiple vent holes 1002 are provided on the top surface of the partition 10, and the multiple vent holes 1002 are evenly distributed above the multiple fuel through holes 1001.

[0021] Understandably, this invention divides a traditional fuel spill chamber 1 into two interconnected chambers at the top, with the two chambers connected at approximately 75% of their height. Fuel is spilled through pipelines into the first chamber 101 of the spill chamber for settling and clarification. This chamber is connected to a steam heating coil. Due to fuel's lower density than water, it naturally floats above the water. The steam heating coil, located at the bottom of the chamber, further promotes the separation of fuel from the water, causing it to accumulate on the surface. As the fuel level rises, when the fuel level exceeds 75% of the height of the first chamber 101, it enters the second chamber 102 under gravity. This uses a physical method to promote the separation of fuel and water, leaving a large amount of water in the first chamber 101 and a large amount of fuel in the second chamber 102. The piping inlet of the first chamber 101 is connected to the ship's sludge pump 7 and transports water to the sludge tank 2. The piping inlet of the second chamber 102 is connected to the ship's fuel oil transfer pump 8 and transports fuel oil to the fuel oil clarification tank 3 for recycling. The fuel oil in the fuel oil venting tank 1 is a mixture of fuel oil and diesel oil. It is permissible for such a mixture to be transported to the fuel oil clarification tank 3 when the fuel oil is used.

[0022] The system also includes a control system, which includes an electrical control box 12, a moisture detection sensor 13 located in the first chamber 101, and a high-level sensor 11 located in the second chamber 102. The moisture detection sensor 13 is linked and controlled by the oil sludge pump 7, the high-level sensor 11, and the fuel oil transfer pump 8 through the electrical control box 12. The height difference between the sensing end of the moisture detection sensor 13 and the lower edge of the fuel oil through-hole 1001 is not less than 9% of the height of the partition 10. The electrical control box 12 is communicatively connected to the ship's monitoring and alarm system and the ship's automation system. In some embodiments, the sensing end of the moisture detection sensor 13 and the lower edge of the fuel oil through-hole 1001 are located at 65% of the height of the partition 10.

[0023] A moisture detection sensor 13 is designed and installed at 65% height of the first chamber 101 to detect moisture in the oil. When the moisture sensor detects a large amount of moisture, it will issue an alarm to prevent water from the first chamber 101 from entering the second chamber 102.

[0024] Furthermore, a drain pipe 14 is connected between the oil residue conveying pipe 5 and the fuel oil conveying pipe 6. A first valve 15 is provided on the drain pipe 14. A second valve 16 is provided on the oil residue conveying pipe 5 on the side of the oil residue pump 7 near the first chamber 101. A third valve 17 is provided on the fuel oil conveying pipe 6 on the side of the fuel oil conveying pump 8 near the fuel oil clarification chamber 3. The second valve 16 is located on the side of the connection point between the drain pipe 14 and the oil residue conveying pipe 5 near the first chamber 101, and the third valve 17 is located on the side of the drain pipe 14 and the fuel oil conveying pipe 6 near the fuel oil clarification chamber 3. A moisture detection sensor 13 is provided in the second chamber 102, installed at 5% below the low-level alarm sensor of the second chamber. The moisture detection sensor 13 is linked and controlled by the oil residue pump 7 through the electrical control box 12.

[0025] Furthermore, the control system also includes a low liquid level sensor 18 installed on the first chamber 101. The installation height of the low liquid level sensor 18 is 20% to 30% of the chamber height and is located above the suction port of the oil residue conveying pipe 5. The low liquid level sensor 18 and the oil residue pump 7 are linked and controlled by the electrical control box 12.

[0026] Furthermore, a low liquid level sensor 18 is provided on the second chamber 102. The installation height of the low liquid level sensor 18 is 20% to 30% of the chamber height and is located above the suction port of the fuel delivery pipe 6. The low liquid level sensor 18 is linked and controlled by the fuel delivery pump 8 through the electrical control box 12.

[0027] Furthermore, a depth measuring device 19 is provided in both the first chamber 101 and the second chamber 102; a vent pipe 20 is provided at the fuel through hole 1001; a vacuum pressure gauge and a pressure gauge are respectively provided on the front and rear sides of the sludge pump 7 and the fuel delivery pump 8; and a filter 21 is provided on both the sludge delivery pipe 5 and the fuel delivery pipe 6.

[0028] When the moisture detection sensor 13 in the first chamber 101 detects a large amount of moisture, it sends an alarm signal to the electrical control box 12 and the ship's automated monitoring and alarm system. The crew starts the sludge pump 7 on the electrical control box 12. All valves in the pipelines before and after the sludge pump 7 are normally open, and the moisture in the first chamber 101 is transferred to the sludge tank 2 by the sludge pump 7. When the liquid level in the first chamber 101 drops to the height of the low liquid level alarm switch, the low liquid level switch is triggered and sends a control signal to the electrical control box 12, automatically shutting down the sludge pump 7. The low liquid level switch is installed at a height of approximately 25% of the tank height and above the suction port. This ensures the normal operation of the sludge pump 7 while preventing the water in the chamber from being pumped out, causing dry friction and damage to the pump. The sludge pump 7 can also be manually started and automatically stopped. The liquid level in the first chamber 101 can be measured by the depth sounding device 9.

[0029] High-level and low-level switches are installed in the second chamber 102. When the high-level switch in the second chamber 102 sends an alarm signal to the electrical control box 12 and extends to the ship's entire automation system, the crew starts the fuel transfer pump 8 through the electrical control box 12 to pump fuel. All valves on the pipelines before and after the fuel transfer pump 8 are normally open. The fuel in the second chamber 102 is transferred to the fuel sludge tank by the fuel transfer pump 8, and then separated by the fuel separator for recycling. When the fuel transfer pump 8 is working, the fuel level in the second chamber 102 drops to the low-level switch, which automatically stops the fuel transfer pump 8 through the electrical control box 12. The low-level switch is installed at a height of about 25% of the tank height and above the suction port. This ensures the normal operation of the sludge pump 7 while preventing water in the chamber from being pumped out, which could cause dry friction and damage to the pump. The fuel transfer pump 8 can also be manually started and automatically stopped.

[0030] If a large amount of water enters the second chamber 102 for any reason, the moisture detection sensor 13 of the second chamber 102 will send an alarm to the electrical control box 12 and extend to the ship-wide monitoring and alarm system. The first valve 15 between the two pumps will be opened, while the second valve 16 and the third valve 17 will be closed. The oil sludge pump 7 will be manually started through the electrical control box 12 to transfer water to the oil sludge tank 2. The liquid level in the second chamber 102 can be detected by the depth sounding device to ensure that the tank is completely emptied of water or fuel oil.
