DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] Reference Figure 1 , Figure 1 1 is a simplified structural diagram of a fuel oil monitoring and purification device 100 according to some embodiments of the present disclosure. The present invention provides a fuel oil monitoring and purification device 100, comprising: an oil delivery component 110, a moisture monitoring component 20, and a particle monitoring component 21.

[0022] The oil delivery assembly 110 includes a first pipeline A, an oil-water separator 8 and an oil filter 13. A first switch valve 9 and a second switch valve 12 are provided on the first pipeline A. The inlet 81 and the outlet 82 of the oil-water separator 8 are both connected to the first pipeline A, and the oil-water separator 8 is connected in parallel with the first switch valve 9. The inlet 131 and the outlet 132 of the oil filter 13 are both connected to the first pipeline A, and the oil filter 13 is connected in parallel with the second switch valve 12.

[0023] The moisture monitoring component 20 is in communication with the first pipeline A and is used to monitor the moisture content of the oil in the first pipeline A. The particle monitoring component 21 is in communication with the first pipeline A and is used to monitor the particles in the oil in the first pipeline A.

[0024] The fuel oil monitoring and purification device 100 is configured as follows:

[0025] When the moisture monitoring component 20 detects that the moisture content of the oil exceeds the standard moisture value, the first switch valve 9 is closed and the second switch valve 12 is opened, so that the oil in the first pipeline A passes through the oil-water separator 8.

[0026] When the moisture monitoring component 20 detects that the moisture content of the oil is lower than or equal to the standard moisture value and the particle monitoring component 21 detects that the oil particles exceed the standard particle value, the first switch valve 9 opens and the second switch valve 12 closes, so that the oil in the first pipeline A passes through the oil filter 13.

[0027] When the moisture monitoring component 20 detects that the moisture content of the oil exceeds the standard moisture value and the particle monitoring component 21 detects that the oil particles exceed the standard particle value, the first switch valve 9 is first closed and the second switch valve 12 is opened, so that the oil in the first pipeline A is first processed by the oil-water separator 8. When the moisture content of the oil is lower than or equal to the standard moisture value, the first switch valve 9 is opened and the second switch valve 12 is closed, so that the oil in the first pipeline A with moisture content lower than or equal to the standard moisture value and oil particles exceeding the standard particle value passes through the oil filter 13.

[0028] When the moisture monitoring component 20 detects that the moisture content of the oil is equal to or lower than the standard moisture value and the particle monitoring component 21 detects that the particles in the oil are equal to or lower than the standard particle value, both the first on-off valve 9 and the second on-off valve 12 are opened, allowing the oil to pass through the first on-off valve 9 and the second on-off valve 12 and be transported in the first pipeline A. In other words, the oil does not pass through the oil-water separator 8 and the oil filter 13.

[0029] In the above technical solution, since the oil particle value monitored by the particle monitoring component is accurate when the oil moisture content is qualified, if the particle monitoring component monitors that the oil particles are unqualified, the oil is filtered through the oil filter 13, which reduces unnecessary filtering operations, reduces the consumption cost of consumables inside the oil filter, and at the same time improves the purification efficiency.

[0030] First pipeline A is the main pipeline for transporting oil in fire-resistant fuel monitoring and purification device 100. First pipeline A includes an oil inlet A1 and an oil outlet A2. Oil inlet A1 can be connected to an oil storage tank, and oil outlet A2 can be connected to an oil storage tank. Oil in the oil storage tank enters first pipeline A through oil inlet A1 and then returns to the oil storage tank through oil outlet A2. For example, oil inlet A1 can be connected to the bottom of the oil storage tank, and oil outlet A2 can be connected to the top of the oil storage tank.

[0031] Initially, oil enters first pipeline A through oil inlet A1, passes through oil pump 4, first on / off valve 9, second on / off valve 12, and drain valve 17, and flows out of oil outlet A2. Simultaneously, moisture monitoring component 20 and particle monitoring component 21 are activated to monitor the oil in first pipeline A.

[0032] When the moisture monitoring component 20 detects that the moisture content of the oil exceeds the standard moisture value (when the moisture content of the oil is unqualified), the first switch valve 9 is closed and the second switch valve 12 is opened. The oil in the first pipeline A enters the oil-water separator 8 through the first oil delivery bypass A-1 for dehydration. The oil after dehydration does not enter the oil filter 13, but flows out from the oil outlet A2 through the second switch valve 12.

[0033] If the particle monitoring component 21 detects that the oil particles are unqualified when the oil moisture content is unqualified, the oil particle monitoring result may be inaccurate. In other words, the oil particle size may actually be qualified. If the oil is allowed to enter the oil filter 13, unnecessary operation will be caused, shortening the service life of the oil filter 13. Therefore, when the moisture monitoring component 20 detects that the oil moisture content exceeds the standard moisture value, the oil in the first pipeline A enters the oil-water separator 8 for dehydration treatment, and does not enter the oil filter 13, thereby reducing unnecessary filtering operations.

[0034] When the moisture monitoring component 20 detects that the oil moisture content is less than or equal to the standard moisture content (when the oil moisture content is qualified) and the particle monitoring component 21 detects that the oil particles exceed the standard particle content (when the oil particles are unqualified), the oil particle monitoring result is accurate. The first on-off valve 9 can be opened and the second on-off valve 12 can be closed, preventing the oil in the first pipeline A from entering the oil-water separator 8. Instead, the oil enters the oil filter 13 through the second oil delivery bypass A-2 for filtration. This allows for targeted oil filtration and reduces the cost of the oil filter 13.

[0035] When the moisture monitoring component 20 detects that the moisture content of the oil exceeds the standard moisture value and the particle monitoring component 21 detects that the oil particles exceed the standard particle value, that is, when both the moisture content of the oil and the oil particles are unqualified, the oil particle monitoring result may be inaccurate at this time, so dehydration treatment is required first. First, close the first switch valve 9 and open the second switch valve 12, so that the oil in the first pipeline A is processed by the oil-water separator 8. When the moisture content of the oil after dehydration treatment is lower than or equal to the standard moisture value (when the oil moisture content is qualified), if the particle monitoring component 21 detects that the oil particles are still unqualified at this time, the oil particle monitoring result at this time is accurate, and the first switch valve 9 can be opened and the second switch valve 12 can be closed, so that the oil in the first pipeline A enters the oil filter 13 for filtration treatment.

[0036] In some embodiments, the inlet 81 of the oil-water separator 8 is connected to the inlet of the first switch valve 9 through a first connecting point d1 on the first pipeline A, and the outlet of the oil-water separator 8 is connected to the outlet of the first switch valve 9 through a second connecting point d2 on the first pipeline A; the inlet 131 of the oil filter 13 is connected to the inlet of the second switch valve 12 through a third connecting point d3 on the first pipeline A, and the outlet 132 of the oil filter 13 is connected to the outlet of the second switch valve 12 through a fourth connecting point d4 on the first pipeline A, and the second connecting point d2 is located upstream of the third connecting point d3.

[0037] During the oil circulation in first pipeline A, the location the oil passed through at the previous moment is considered upstream, and the location it passes through at the next moment is considered downstream. That is, the location the oil reaches first is considered upstream, and the location it reaches later is considered downstream. Initially, the oil in first pipeline A reaches the second connection point d2 before reaching the third connection point d3.

[0038] The oil-water separator 8 can be connected in parallel with the first switch valve 9 via the first oil delivery bypass A-1. The oil filter 13 can be connected in parallel with the second switch valve 12 via the second oil delivery bypass A-2.

[0039] Whether the oil dehydrated by the oil-water separator 8 and the oil filtered by the oil filter 13 are qualified can be measured by the moisture monitoring component 20 and the particle monitoring component 21. For example, the oil dehydrated by the oil-water separator 8 and the oil filtered by the oil filter 13 can be measured by the moisture monitoring component 20 and the particle monitoring component 21 to determine whether they are qualified.

[0040] The oil dehydrated by the oil-water separator 8 can also be tested for quality by sampling and measuring the oil through the sampling line C provided on the first pipeline A. The inlet of the sampling line C is located downstream of the fourth connection point d4, and the sampling line C is provided with a sampling valve 15. The processed oil collected through the sampling line C can be measured in a laboratory, which provides more accurate results. The laboratory measurement results can be compared with the measurement results of the moisture monitoring component 20 and the particle monitoring component 21 to calibrate the moisture monitoring component 20 and the particle monitoring component 21 and determine whether the monitoring results of the moisture monitoring component 20 and the particle monitoring component 21 are accurate.

[0041] In some embodiments, the fire-resistant fuel monitoring and purification device 100 further includes a second pipeline B, which is connected to the first pipeline A. The moisture monitoring component 20 and the particle monitoring component 21 are arranged on the second pipeline B, and the outlet of the moisture monitoring component 20 is connected to the inlet of the particle monitoring component 21.

[0042] During the oil circulation process in first pipeline A, a portion of the oil in first pipeline A flows into the inlet of second pipeline B and flows out of the outlet of second pipeline B. Moisture monitoring assembly 20 and particle monitoring assembly 21 are connected in series to second pipeline B. The oil in first pipeline A first passes through moisture monitoring assembly 20 and then through particle monitoring assembly 21, reducing the complexity of the design of second pipeline B.

[0043] Furthermore, the inlet of the second pipeline B is located upstream of the first connecting point d1, that is, the inlet of the second pipeline B is connected to the first pipeline A and is located upstream of the first connecting point d1; the outlet of the second pipeline B is connected to the second oil delivery bypass A-2, and a check valve 10 is provided on the second oil delivery bypass (A-2), and the outlet of the second pipeline B is located between the inlet of the oil filter 13 and the outlet of the check valve 10.

[0044] The oil entering the inlet of second pipeline B is pre-processed oil to ensure measurement accuracy. The oil flowing out of the outlet of second pipeline B is filtered by oil filter 13 before flowing out of oil outlet A2 of first pipeline A. The oil in second pipeline B is also filtered, reducing oil contamination.

[0045] Furthermore, an inlet valve 18, a pressure reducing valve 19 and an oil outlet valve 23 are also provided on the second pipeline B. The inlet valve 18, the pressure reducing valve 19, the moisture monitoring component 20, the particle monitoring component 21 and the oil outlet valve 23 are distributed in sequence in the oil flow direction of the second pipeline B.

[0046] In some embodiments, an oil suction filter 2 is further provided on the first pipeline A. The outlet of the oil suction filter 2 is located upstream of the inlet of the second pipeline B. The filtering accuracy of the oil suction filter 2 is lower than that of the oil filter 13.

[0047] Before the oil in the first pipeline A enters the second pipeline B, it is first coarsely filtered by the oil suction filter 2 to filter out larger particles and other impurities, and then enters the second pipeline B, reducing damage to the moisture monitoring component 20 and the particle monitoring component 21 on the second pipeline B.

[0048] Furthermore, the inlet of the oil pump 4 is connected to the outlet of the oil suction filter 2, and the outlet of the oil pump 4 is connected to the inlet of the second pipeline B. The oil entering the oil pump 4 is first filtered by the oil suction filter 2 to reduce damage to the oil pump 4.

[0049] Furthermore, the fuel-resistant oil monitoring and purification device 100 includes a relief valve 3. The inlet of relief valve 3 is connected to the outlet of the oil pump 4, and the outlet of relief valve 3 is connected to the inlet of the oil suction filter 2. If the oil flow pressure in the fuel-resistant oil monitoring and purification device 100 is too high, the pressure can be relieved through relief valve 3, thereby protecting the fuel-resistant oil monitoring and purification device 100.

[0050] In some embodiments, a flow sensor 22 is further provided on the second pipeline B, disposed between the outlet of the particle monitoring assembly 21 and the inlet of the oil outlet valve 23. Excessive or insufficient oil flow in the second pipeline B may cause inaccurate monitoring by the moisture monitoring assembly 20 and the particle monitoring assembly 21. Monitoring the oil flow in the second pipeline B through the flow sensor 22 facilitates timely monitoring of the oil flow status and facilitates timely adjustments.

[0051] The fire-resistant fuel oil monitoring and purification device 100 also includes a differential pressure alarm 14. One end of the differential pressure alarm 14 is connected to the inlet of the oil filter 13, and the other end of the differential pressure alarm 14 is connected to the outlet of the oil filter 13. If the filter material in the oil filter 13 is not replaced for a long time, it will develop excessive resistance and need to be replaced promptly. When the pressure difference between the inlet and outlet of the oil filter 13 is too large, it indicates that the filter material in the oil filter 13 is too high, and the differential pressure alarm 14 will sound an alarm, so that it can be replaced promptly.

[0052] In some embodiments, the fuel oil monitoring and purification device 100 includes a first pipeline A, a second pipeline B, an oil-water separator 8 and an oil filter 13 .

[0053] The first pipeline A is equipped with, in order from upstream to downstream, an oil inlet valve 1, an oil suction filter 2, an oil pump 4, an oil pump outlet valve 5, a pressure transmitter 6, a temperature sensor 7, a first on-off valve 9, a check valve 10, a second on-off valve 12, a second one-way valve 16, and an oil drain valve 17. The inlet of the relief valve 3 is connected to the outlet of the oil pump 4 and is located between the oil pump 4 and the oil pump outlet valve 5. The outlet of the relief valve 3 is connected to the inlet of the oil filter 2 and is located between the inlet valve 1 and the oil filter 2. The oil-water separator 8 is connected in parallel with the first on-off valve 9 via the first oil supply bypass A-1. The oil filter 13 is connected in parallel with the second on-off valve 12 via the second oil supply bypass A-2. The inlet of the differential pressure alarm 14 is connected to the inlet of the oil filter 13, and the outlet of the differential pressure alarm 14 is connected to the outlet of the oil filter 13. A pre-filter pressure sensor 11 is also installed in the pipeline connecting the inlet of the differential pressure alarm 14 to the inlet of the oil filter 13. The pressure transmitter 6, pre-filter pressure sensor 11, and differential pressure alarm 14 constitute the system's pressure monitoring unit, responsible for monitoring the pressure and differential pressure data of various components of the fire-resistant fuel monitoring and purification device 100. The differential pressure alarm 14 generates an alarm in the event of overpressure. The temperature sensor 7 forms the temperature monitoring unit within the fire-resistant fuel monitoring and purification device 100, responsible for monitoring the system's operating temperature.

[0054] The inlet of second pipeline B communicates with first pipeline A and is located between pressure transmitter 6 and temperature sensor 7. The outlet of second pipeline B communicates with second oil delivery bypass A-2 and is located between the inlet of oil filter 13 and the outlet of check valve 10. Second pipeline B is equipped with an inlet valve 18, a pressure reducing valve 19, a moisture monitoring assembly 20, a particle monitoring assembly 21, a flow sensor 22, and an outlet valve 23, in the order in which the oil flows from the inlet to the outlet.

[0055] A sampling pipeline C is further provided on the second pipeline B. The inlet of the sampling pipeline C is located between the inlet of the second one-way valve 16 and the oil filter 13 . The sampling pipeline C is provided with a sampling valve 15 .

[0056] The working process of the fuel oil monitoring and purification device 100 is as follows:

[0057] After the system is started, open the oil inlet valve 1, the oil pump 4, the oil pump outlet valve 5, the first switch valve 9, the second switch valve 12, the second one-way valve 16, and the oil drain valve 17 to put the first pipeline A in a circulating flow state; after the pressure monitored by the pressure sensor is in a stable state, open the inlet valve 18 and the outlet valve 23 of the second pipeline B, so that the oil in the first pipeline A enters the second pipeline B through the inlet of the second pipeline B located between the oil pump outlet valve 5 and the temperature sensor 7, and the pressure reducing valve 19 adjusts the oil pressure to the working pressure range of the sensors in the moisture monitoring component 20 and the particle monitoring component 21, and at the same time starts the moisture monitoring component 20 and the particle size monitoring component 21 to monitor the particle size and moisture index in the fuel oil; at the same time, the flow sensor 22 monitors the flow in the second pipeline B The oil flow is monitored; if the moisture monitoring component 20 detects that the moisture content of the oil is unqualified, the first switch valve 9 is closed, and the oil in the first pipeline A enters the dehydrator 8 for dehydration. After the moisture index of the oil is qualified, the first switch valve 9 is opened, and the oil no longer passes through the oil-water separator 8; if the moisture index of the oil is qualified and the particle monitoring component 21 detects that the particle size exceeds the standard, the second switch valve 12 is closed, and the oil in the first pipeline A enters the oil filter 13 for particle pollutant purification. At this time, the pressure difference alarm 14 connected to the inlet and outlet ends of the oil filter 13 is in operation to avoid operational failures caused by overpressure of the oil filter 13; after the particle size index is qualified, the second switch valve 12 is opened, and the oil no longer passes through the oil filter 13.

[0058] This fire-resistant fuel oil monitoring and purification device monitors the oil's moisture and particle size in real time, and provides feedback on temperature and pressure during the oil purification process. If either moisture or particle size exceeds the standard, targeted treatment can be provided. If both exceed the standard, the offending indicators can be addressed sequentially, preventing the oil's moisture content from interfering with the particle size index. This allows for refined fire-resistant fuel oil processing, avoids excessive oil treatment, saves filter material, and improves efficiency.

[0059] It should be noted that each of the aforementioned valves, such as the first on-off valve 9, the second on-off valve 12, the oil inlet valve 1, the oil pump outlet valve 5, the pressure reducing valve 19, the oil delivery valve 23, and the oil drain valve 17, can be solenoid valves. These valves can be connected to a host computer signal, allowing the host computer to control the opening and closing of the corresponding valves. Furthermore, the moisture monitoring component 20, the particle size monitoring component 21, the temperature sensor 7, and the oil filter pre-pressure sensor 11 can also be connected to the host computer signal, transmitting the monitored data to the host computer in real time. The host computer can then control the opening and closing of the corresponding components based on the received oil data.
