[0018] Figure 2-5 Schematic diagram of fire-resistant oil flow in different states of a fire-resistant oil processing system provided by some embodiments of the present invention. DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figure 1 The present invention provides a fire-resistant oil processing system 100, comprising: an oil circulation device 101, an oil processing component 102 and an oil monitoring device 103.

[0021] The oil circulation device 101 includes a first pipeline A, an oil pump 4 and a first switch valve 16 provided on the first pipeline A. The inlet of the first switch valve 16 is connected to the outlet of the oil pump 4 .

[0022] The oil processing component 102 includes a second pipeline C and an oil processor 110 and a second switch valve 6 arranged on the second pipeline C. The inlet C1 of the second pipeline C is connected to the first pipeline A and is located between the outlet of the oil pump 4 and the inlet of the first switch valve 16. The outlet C2 of the second pipeline C is connected to the first pipeline A and is located between the outlet of the first switch valve 16 and the outlet of the first pipeline A. The outlet of the second switch valve 6 is connected to the inlet of the oil processor 110.

[0023] The oil monitoring device 103 includes a third pipeline B-1 and a monitoring component 22 and a third switch valve 10 arranged on the third pipeline B-1. The inlet B-11 of the third pipeline B-1 is connected to the first pipeline A and is located upstream of the inlet of the oil pump 4. The outlet B-12 of the third pipeline B-1 is connected to the first pipeline A and is located between the outlet of the first switch valve 16 and the outlet of the first pipeline A. The outlet of the third switch valve 10 is connected to the inlet of the monitoring component 22, and the inlet of the monitoring component 22 is connected to the outlet of the second switch valve 6 through the fourth pipeline B-2.

[0024] The fire-resistant oil treatment system is configured such that when the monitoring component 22 detects that the oil is qualified, the second on-off valve 6 is closed, and the first on-off valve 16 and the third on-off valve 10 are opened. When the monitoring component 22 detects that the oil is unqualified, the second on-off valve 6 is opened, and the first on-off valve 16 and the third on-off valve 10 are closed.

[0025] The inlet and outlet of the first pipeline A are used to communicate with the oil tank of the oil-consuming equipment. The anti-fire oil in the oil tank enters the first pipeline A from the inlet of the first pipeline A and returns to the oil tank from the outlet of the first pipeline A, forming a circulating oil circuit.

[0026] See also Figure 2 In the initial state, or when the fire-resistant oil is in a qualified condition, a portion (most) of the fire-resistant oil entering the inlet of the first pipeline A enters the oil pump 4, passes through the first on-off valve 16, and exits the outlet of the first pipeline A. The remaining portion (a small portion) of the fire-resistant oil enters the third pipeline B-1 through the inlet B-11, passes through the third on-off valve 10, and then exits the outlet of the first pipeline A. It then returns to the first pipeline A through the outlet B-12 of the third pipeline B-1 and exits the outlet of the first pipeline A. In other words, the fire-resistant oil discharged from the outlet of the oil pump 4 does not enter the second pipeline C, that is, it is not processed by the oil treatment unit 110. Because the fire-resistant oil in the tank is in a circulating state, the third pipeline B-1 is connected to the first pipeline A, allowing the monitoring unit 22 to monitor the fire-resistant oil data in real time, resulting in more accurate monitoring results.

[0027] See also Figure 3 and Figure 4 When the monitoring assembly 22 detects that the fire-resistant oil indicators are unqualified, the first on-off valve 16 closes. The fire-resistant oil entering the inlet of the first pipeline A enters the oil pump 4. The fire-resistant oil discharged from the outlet of the oil pump 4 enters the second pipeline C and passes through the second on-off valve 6 and the oil treatment device 110. After being treated by the oil treatment device 110, the fire-resistant oil returns to the first pipeline A from the outlet C2 of the second pipeline C and flows out of the outlet of the first pipeline A. Simultaneously, the fire-resistant oil flowing out of the outlet of the second on-off valve 6 flows through the third pipeline B-2 and passes through the monitoring assembly 22 for real-time monitoring. The fire-resistant oil flowing out of the monitoring assembly 22 returns to the first pipeline A from the outlet B-12 of the third pipeline B-1 and flows out of the outlet of the first pipeline A. In other words, the fire-resistant oil entering the inlet of the first pipeline A does not enter the third on-off valve 10, and the fire-resistant oil discharged from the outlet of the oil pump 4 does not enter the first on-off valve 16.

[0028] Typically, when the fire-resistant oil passes the inspection, the oil entering the monitoring assembly 22 can meet the flow rate monitoring requirements without passing through the oil pump 4. If the fire-resistant oil fails the inspection and needs to be processed, the oil entering the monitoring assembly 22 passes through the oil pump 4, i.e., the oil pump 4 pumps the fire-resistant oil into the monitoring assembly 22. This accelerates the circulation of the fire-resistant oil entering the monitoring assembly 22, allowing the monitoring assembly 22 to promptly detect whether the treated fire-resistant oil passes the inspection. If so, the oil processor 110 can be shut down immediately, avoiding unnecessary processing operations and extending the service life of the oil processor 110.

[0029] In some embodiments, the fire-resistant oil processing system 100 includes a dehydrator 7 , a regenerator 9 , a fourth on-off valve 11 , and a fifth on-off valve 12 .

[0030] The dehydrator 7 and the regenerator 9 are arranged on the second pipeline C, the inlet of the fourth switch valve 11 and the inlet of the dehydrator 7 are connected to the first connecting point d1 on the second pipeline C, the first connecting point d1 is connected to the outlet of the second switch valve 6, the outlet of the fourth switch valve 11 and the outlet of the dehydrator 7 are connected to the second connecting point d2 on the second pipeline C, the inlet of the fifth switch valve 12 and the inlet of the regenerator 9 are connected to the third connecting point d3 on the second pipeline C, the third connecting point d3 is located downstream of or coincides with the second connecting point d2, and the outlet of the fifth switch valve 12 and the outlet of the regenerator 9 are connected to the fourth connecting point d4 on the second pipeline C.

[0031] The fire-resistant oil treatment system 100 is configured as follows: when the monitoring component 22 detects that the water content of the oil is unqualified, the second switch valve 6 and the fifth switch valve 12 are opened, and the first switch valve 16, the third switch valve 10, and the fourth switch valve 11 are closed; when the monitoring component 22 detects that the dielectric constant of the oil is unqualified, the second switch valve 6 and the fourth switch valve 11 are opened, and the first switch valve 16, the third switch valve 10, and the fifth switch valve 12 are closed.

[0032] See also Figure 3 When the monitoring assembly 22 detects that the oil contains unacceptable moisture, the fire-resistant oil discharged from the outlet of the oil pump 4 enters the second pipeline C, passes through the second on-off valve 6, the dehydrator 7, and the fifth on-off valve 12. After being dehydrated by the dehydrator 7, the fire-resistant oil returns from the outlet of the second pipeline C to the first pipeline A through the outlet C2, and finally flows out of the outlet of the first pipeline A. Simultaneously, the fire-resistant oil flowing from the outlet of the second on-off valve 6 flows through the monitoring assembly 22 via the third pipeline B-2 for real-time monitoring. The fire-resistant oil flowing from the monitoring assembly 22 returns to the first pipeline A through the outlet B-12 of the third pipeline B-1, and finally flows out of the outlet of the first pipeline A. In other words, the fire-resistant oil flowing from the outlet of the second on-off valve 6 does not pass through the fourth on-off valve 11 or the regenerator 9.

[0033] See also Figure 4When the monitoring assembly 22 detects that the dielectric constant of the oil is unacceptable, the fire-resistant oil discharged from the outlet of the oil pump 4 enters the second pipeline C, passes through the second on-off valve 6, the fourth on-off valve 11, and the regenerator 9 in sequence. After being processed by the regenerator 9, the fire-resistant oil returns from the outlet of the second pipeline C to the first pipeline A through the outlet C2, and finally flows out of the outlet of the first pipeline A. Simultaneously, the fire-resistant oil flowing out of the outlet of the second on-off valve 6 flows through the monitoring assembly 22 via the third pipeline B-2 for real-time monitoring. The fire-resistant oil flowing out of the monitoring assembly 22 returns to the first pipeline A through the outlet B-12 of the third pipeline B-1, and finally flows out of the outlet of the first pipeline A. In other words, the fire-resistant oil flowing out of the outlet of the second on-off valve 6 does not pass through the fifth on-off valve 12 or the dehydrator 7.

[0034] In some embodiments, the oil monitoring device also includes a sixth switch valve 24 and a seventh switch valve 23 arranged on the third pipeline B-1, the inlet of the sixth switch valve 24 is connected to the outlet of the third switch valve 10 and the outlet of the second switch valve 6, the outlet of the sixth switch valve 24 is connected to the inlet of the monitoring component 22, and the inlet of the seventh switch valve 23 is connected to the outlet of the monitoring component 22.

[0035] The monitoring component 22 includes a box body, a moisture sensor arranged in the box body, a dielectric constant monitor and a monitoring pump. The inlet of the box body is connected to the outlet of the sixth switch valve 24, and the outlet of the box body is connected to the inlet of the seventh switch valve 23. The power of the monitoring pump is less than the power of the oil pump 4.

[0036] Because third pipeline B-1, as a monitoring pipeline, typically has a relatively small diameter, the monitoring pump can meet the required flow rate of fire-resistant oil entering monitoring assembly 22 in the initial state or when the fire-resistant oil is qualified. If the fire-resistant oil fails to meet the requirements, oil pump 4 pumps the fire-resistant oil into monitoring assembly 22. At this time, the monitoring pump can be shut down to save costs.

[0037] See also Figure 5 In some embodiments, the inlet 71 of the dehydrator 7 is lower than the outlet 72 of the dehydrator 7, and the inlet 91 of the regenerator 9 is lower than the outlet 92 of the regenerator 9. An inlet switch valve 1 is provided on the first pipeline A. The outlet of the inlet switch valve 1 is connected to the inlet B-11 of the third pipeline B-1 and the inlet of the oil pump 4.

[0038] The fire-resistant oil treatment system 100 is configured as follows: when the dehydrator 7 and the regenerator 9 need to drain oil, the inlet switch valve 1, the second switch valve 6, and the fifth switch valve 12 are closed, and the third switch valve 10, the fourth switch valve 11 and the first switch valve 16 are opened.

[0039] When the dehydrator 7 and / or regenerator 9 needs to drain oil, the fire-resistant oil in the regenerator 9 and the fire-resistant oil in the dehydrator 7 enter the fourth pipeline B-2 from the inlet 91 of the regenerator 9 and the inlet 71 of the dehydrator 7 respectively. The fire-resistant oil flowing out of the outlet of the fourth pipeline B-2 enters the third pipeline B-1, passes through the third switch valve 10, and enters the first pipeline A from the inlet B-11 of the third pipeline B-1. It passes through the oil pump 4 and the first switch valve 16 on the first pipeline A in sequence and flows out from the outlet of the first pipeline A.

[0040] When the filter element in the dehydrator 7 and / or regenerator 9 needs to be replaced, the oil must be drained before the filter element is replaced. In the related art, the fire-resistant oil in the dehydrator 7 and / or regenerator 9 is manually drained before the filter element is replaced. This is not only inconvenient but also results in waste of fire-resistant oil. The disclosed technical solution, based on the existing pipeline, uses an oil pump to discharge the fire-resistant oil in the dehydrator 7 and / or regenerator 9 from the outlet of the first pipeline A and return it to the oil tank of the oil-consuming equipment, thereby improving oil drainage efficiency and avoiding fire-resistant oil waste.

[0041] In some embodiments, see Figure 5 The inlet C1 of the second pipeline C is connected to the fifth connection point on the first pipeline A. A pressure transmitter 5 is provided on the first pipeline A, and the inlet of the pressure transmitter 5 is connected to the fourth connection point d4. The fire-resistant oil treatment system 100 is configured such that when the pressure transmitter 5 detects that the oil pressure exceeds a threshold, the inlet on-off valve 1, the second on-off valve 6, and the fifth on-off valve 12 are closed, and the third on-off valve 10, the fourth on-off valve 11, and the first on-off valve 16 are opened.

[0042] During the oil treatment process, if the pressure transmitter 5 detects that the oil pressure exceeds the threshold, the oil can be drained from the dehydrator 7 and / or regenerator 9 through the oil pump so that the filter element of the dehydrator 7 and / or regenerator 9 can be replaced in time.

[0043] During the oil draining process of the dehydrator 7 and / or the regenerator 9, the sixth switch valve 24 can be closed to prevent the anti-fire oil in the monitoring component 22 from flowing back, and the seventh switch valve 23 can be closed to prevent the anti-fire oil in the first pipeline A from flowing into the monitoring component 22.

[0044] In some embodiments, the fire-resistant oil treatment system 100 further includes a first filter 18 disposed on the first pipeline A. The inlet of the first filter 18 is connected to the outlet B-12 of the third pipeline B-1, the first switch valve 16 and the outlet C2 of the second pipeline C.

[0045] In the initial state, when the fire-resistant oil is qualified, when the fire-resistant oil index is unqualified, and when draining the dehydrator 7 and / or regenerator 9, the fire-resistant oil before the outlet of the first pipeline A is first filtered through the first filter 18. Two first filters 18 can be provided, and the two first filters 18 are connected in parallel on the first pipeline A.

[0046] In some embodiments, the fire-resistant oil treatment system 100 further includes a second filter 14 and a one-way valve 15 arranged on the second pipeline C, the inlet of the second filter 14 is connected to the fourth connection point d4, the filtering accuracy of the second filter 14 is lower than the filtering accuracy of the first filter 18, and the inlet of the one-way valve 15 is connected to the outlet of the second filter 14.

[0047] When the fire-resistant oil index is unqualified, the fire-resistant oil after being processed by the oil processor 110 is first coarsely filtered by the second filter 14 and then finely filtered by the first filter valve 18. The two-stage filtration improves the filtering effect.

[0048] When the dehydrator 7 and / or the regenerator 9 is drained, the one-way valve 15 prevents the fire-resistant oil in the first pipeline A from flowing back into the second pipeline C.

[0049] In some embodiments, the fire-resistant oil processing system 100 further includes a sampling line E. The inlet of the sampling line E is connected to the second line C and is located downstream of the outlet of the first filter 18 . The sampling line E is provided with a sampling valve 19 .

[0050] The treated fire-resistant oil collected through sampling line C can be measured in a laboratory, which provides more accurate measurement results. Furthermore, the laboratory measurement results can be compared with the monitoring results of the moisture sensor and dielectric constant monitor to calibrate the moisture sensor and dielectric constant monitor and determine whether the monitoring results of the moisture sensor and dielectric constant monitor are accurate.

[0051] In some embodiments, the fire-resistant oil treatment system 100 further includes a differential pressure sensor 17. The inlet of the differential pressure sensor 17 is connected to the inlet of a first filter 18, and the outlet of the differential pressure sensor 17 is connected to the outlet of the first filter 18. The filter material in the first filter 18 may experience excessive resistance after prolonged use. When the pressure difference between the inlet and outlet of the first filter 18 is too large, the filter material in the first filter 18 is experiencing excessive resistance, and the differential pressure sensor 17 issues a prompt to prompt timely replacement.

[0052] In some embodiments, the fire-resistant fuel oil processing system 100 further includes an oil suction filter 2 and a relief valve 3. The inlet of the oil suction filter 2 is connected to the outlet of the inlet on-off valve 1, and the outlet of the oil suction filter 2 is connected to the inlet of the oil pump 4. The inlet of the relief valve is connected to the outlet of the oil pump 4, and the outlet of the relief valve 3 is connected to the inlet of the oil suction filter 2. If the oil flow pressure in the fire-resistant fuel oil processing system 100 is excessive, the pressure can be relieved through the relief valve 3, thereby protecting the fire-resistant fuel oil processing system 100.
