The heat conducting oil transmits the temperature to the seal oil by the heat exchanger 12, so that the seal oil avoids direct contact with the heat resistance heater 11, and the heat conducting oil and the seal oil are circulated in their respective loops during the heating process, preventing the uneven heating of the seal oil during the heating process from causing local temperature to be too high to cause the seal oil to be scorched and deteriorated, and ensuring that the seal oil after dehydration has sufficient sealing effect.

[0024] Specifically, the heat conducting oil is heated by the heater 11 to be warmed to 105-120 DEG C. The seal oil and the heat conducting oil are respectively introduced into the heat exchanger 12, the heat conducting oil transmits the temperature to the seal oil by the heat exchanger 12, so that the seal oil avoids direct contact with the heat resistance heater 11, and the heat conducting oil and the seal oil are circulated in their respective loops during the heating process, preventing the uneven heating of the seal oil during the heating process from causing local temperature to be too high to cause the seal oil to be scorched and deteriorated, and ensuring that the seal oil after dehydration has sufficient sealing effect. The dehydration process in the present application is not limited by the water content of the seal oil, has high water removal rate, and will not cause the seal oil to be scorched and deteriorated.

Specifically, in the initial process, the heater 11 maintains constant power, and the heat conducting oil circuit is formed through the second oil pump 13 to constantly heat the heat conducting oil, so that the heat conducting oil is heated to 105℃-120℃; in the process of heating the oil seal oil, the power of the heater 11 is adjusted through the data of the second temperature sensor, so that the temperature of the heat conducting oil discharged from the outlet of the heater 11 is in the temperature range of 105℃-120℃, maintaining the stability of the temperature of the heat conducting oil.

The first temperature sensor 16 is used to detect the temperature of the heat conducting oil in the heat conducting oil tank 15; in the initial process, the heat conducting oil in the heat conducting oil tank 15 needs to be heated to 105℃-120℃, and then the heat conducting oil is used to heat the oil seal oil, realizing the dehydration of the oil seal oil by heating.

[0026] In the embodiment, the third temperature sensor 2 is arranged in the oil seal oil tank 1, and the temperature of the oil seal oil in the oil seal oil tank 1 is detected to avoid the temperature of the oil seal oil being too high. When the temperature of the oil seal oil exceeds 120℃, the controller sends an electric signal to stop the first oil pump 7. The oil seal oil tank 1 is also provided with a liquid level sensor 17 and a water content sensor 3. The liquid level sensor 17 is used to detect the liquid level of the oil seal oil in the oil seal oil tank 1, and the oil seal oil tank 1 is connected to an oil injection valve 9. When the liquid level of the oil seal oil is too low, new oil seal oil can be injected into the oil seal oil tank 1 through the oil injection valve 9. The water content sensor 3 is a sensor for detecting water content of the AFO series of KOBOLD or the MT162 sensor of Vaisala technology. Of course, other specifications of water content sensors 3 can also be used, which are not limited here. The water content sensor 3 is used to detect the water content in the oil seal oil. When the water content in the oil seal oil is less than 300ppm, it is considered that the dehydration process of the oil seal oil has been completed.

[0027] The first electromagnetic valve 5 is arranged on the connection circuit of the oil seal oil tank 1 and the first oil pump 7, the second electromagnetic valve 14 is arranged on the connection circuit of the heat conducting oil tank 15 and the second oil pump 13, and the first electromagnetic valve 5 and the second electromagnetic valve 14 are in a normally closed state after dehydration is completed to avoid affecting the normal work of the oil seal oil. The oil seal oil tank 1 is connected to the first blowdown valve 6, and the heat conducting oil tank 15 is connected to the second blowdown valve 4. When necessary, the oil seal oil in the oil seal oil tank 1 can be discharged through the first blowdown valve 6, and the heat conducting oil in the heat conducting oil tank 15 can be discharged through the second blowdown valve 4. The connection circuit of the first oil pump 7 and the heat exchanger 12 is also provided with an oil filter 8, which is used to filter the oil seal oil to ensure the purity of the oil seal oil and thus ensure the oil sealing effect of the oil seal oil. The third electromagnetic valve 10 is arranged between the oil filter 8 and the heat exchanger 12, and the third electromagnetic valve 10 is in a normally closed state after dehydration is completed.

[0028] The first oil pump 7, the second oil pump 13, the first temperature sensor 16, the second temperature sensor, the third temperature sensor 2, the liquid level sensor 17, and the battery valve are all mature existing technologies, and their specific structures are not limited here.

[0029] Referring to Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the heat exchanger 12 comprises: a base 121; the base 121 is the structural basis of the heat exchanger 12, and other structures on the heat exchanger 12 are directly or indirectly mounted to the heat exchanger 12. A heat exchange tank 122 is arranged on the base 121; an end head 127 is connected to the heat exchange tank 122, and the end head 127 is provided with an upper chamber and a lower chamber; an end plate 1226 is arranged between the heat exchange tank 122 and the end head 127; the heat exchange tank 122, the end head 127 and the end plate 1226 are connected together by a screw rod and a locking nut. A heat exchange pipeline 1218 is arranged on the end plate 1226; the heat exchange pipeline 1218 is generally in the shape of U, one end of the heat exchange pipeline 1218 communicates with the upper chamber, and the other end of the heat exchange pipeline 1218 communicates with the lower chamber, and the heat exchange pipeline 1218 is connected with the end plate 1226 by a clamping, bonding or pipe fitting connection. A first oil port 128 is arranged on the end head 127, and the first oil port 128 communicates with the upper chamber; a second oil port 126 is arranged on the end head 127, and the second oil port 126 communicates with the lower chamber; the oil seal oil flows into the upper chamber from the first oil port 128, flows into the lower chamber through the heat exchange pipeline 1218, and finally flows out from the second oil port 126. A first medium port is arranged on the heat exchange tank 122; a second medium port 123 is arranged on the heat exchange tank 122. The heat conducting oil flows into the heat exchange tank 122 from the first medium port and flows out from the second medium port 123. The heat exchange pipeline 1218 is arranged in the heat exchange tank 122, and the oil seal oil in the heat exchange pipeline 1218 is fully exchanged with the heat conducting oil in the heat exchange tank 122, so that the oil seal oil is quickly heated, and the heat conducting oil can uniformly heat the oil seal oil in the heat exchange pipeline 1218. The temperature of the heat conducting oil is also in the range of 105-120°C, so that the oil seal oil is almost impossible to coke during the heating process. The heat exchange between the heat conducting oil and the oil seal oil is realized by the heat exchange tank 122 and the heat exchange pipeline 1218, and the heat conducting oil and the oil seal oil circulate in different circuits, which can uniformly heat the oil seal oil to the dehydration temperature without affecting the oil seal oil, and effectively complete the dehydration of the oil seal oil.

[0030] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the heat exchanger 12 further comprises: a steam outlet 1219 arranged on the end head 127. In the process of continuously circulating and heating the oil seal oil, water vapor will also accumulate in the upper chamber of the end head 127, and the arrangement of the steam outlet 1219 can better discharge these water vapor.

[0031] It can be understood that the oil seal oil tank 1 is also provided with an exhaust port for discharging water vapor to avoid the danger caused by the accumulation of water vapor. After the water vapor is discharged, it can effectively avoid the condensation of the water vapor mixed into the oil seal again, ensuring the dehydration effect.

[0032] Referring to Figure 2 , Figure 3 and Figure 4 In some embodiments, the heat exchanger 12 further comprises: a mounting rod, the end plate 1226 is provided with the mounting rod; the end plate 1226 is screwed with the mounting rod, and a plurality of baffles 1217 are arranged on the mounting rod. The baffles 1217 are connected to the mounting rod by welding or bonding. The arrangement of the baffles 1217 can bend the flow path of the heat transfer oil, effectively lengthening the flow path of the heat transfer oil, so that the heat transfer oil can better contact and exchange heat with the oil seal oil in the heat exchange pipeline 1218, improving the heat exchange effect.

[0033] Referring to Figure 2 , Figure 3 and Figure 4 In some embodiments, the heat exchanger 12 further comprises: a first mounting plate 125, the heat exchange tank 122 is mounted to the base 121 through the first mounting plate 125. The first mounting plate 125 is connected to the heat exchange tank 122 by welding, and the first mounting plate 125 is detachably mounted to the base 121 by fasteners, realizing the connection between the base 121 and the heat exchange tank 122.

[0034] Referring to Figure 3 , Figure 7 and Figure 8As shown, in some embodiments, the heat exchanger 12 further comprises: two pull plates 1216; the two pull plates 1216 are connected with a tensioning screw 1214 and a locking nut; a plurality of heat exchange plates 1213; the plurality of heat exchange plates 1213 are arranged between the two pull plates 1216; two adjacent heat exchange plates 1213 enclose a flow cavity; the flow cavity comprises a heat conduction oil cavity and an oil seal oil cavity; the heat conduction oil cavity and the oil seal oil cavity are arranged at intervals; the plurality of heat exchange plates 1213 in the middle are pressed together by the tensioning screw 1214, the locking nut and the two pull plates 1216. A third oil port 1224 is arranged on the pull plate 1216, and the third oil port 1224 communicates with the oil seal oil cavity; a fourth oil port 1212 is arranged on the pull plate 1216, and the fourth oil port 1212 communicates with the oil seal oil cavity; the fourth oil port 1212 communicates with the first oil port 128; a third medium port 1210 is arranged on the pull plate 1216, and the third medium port 1210 communicates with the heat conduction oil cavity; the third medium port 1210 communicates with the second medium port 123; a fourth medium port 1211 is arranged on the pull plate 1216, and the fourth medium port 1211 communicates with the heat conduction oil cavity. The third oil port 1224 is connected with the first oil pump 7; the oil seal oil discharged from the oil seal oil tank 1 flows into the plurality of oil seal oil cavities through the third oil port 1224, and then flows out from the fourth oil port 1212; after flowing out, the oil seal oil flows into the heat exchange pipeline 1218 through the first oil port 128 to perform secondary heat exchange. The heat conduction oil flows into the heat exchange tank 122 through the first medium port, and then flows to the third medium port 1210 through the second medium port 123; the heat conduction oil flows to the plurality of heat conduction oil cavities through the third medium port 1210, and exchanges heat with the oil seal oil in the oil seal oil cavities; finally, the heat conduction oil flows to the heat conduction oil tank 15 through the fourth medium port 1211.

[0035] In this embodiment, the arrangement of the pull plate 1216 and the heat exchange plate 1213 can, on the one hand, effectively extend the heat exchange path, improve the heat exchange efficiency between the heat transfer oil and the oil seal oil, and enable the oil seal oil to quickly heat up to the dehydration temperature. On the other hand, the pull plate 1216 and the heat exchange plate 1213 form a preheating zone, and the heat exchange tube forms a dehydration zone. Since the temperature of the heat transfer oil is not high, the temperature of some of the heat transfer oil will drop rapidly during the heat exchange process, making it impossible to quickly heat the oil seal oil to the dehydration temperature, affecting the heating efficiency. Furthermore, continuous heating will cause the heat transfer oil to deteriorate rapidly, which is not conducive to the long-term use of the heat transfer oil. The separation of the preheating and dehydration zones effectively heats the oil-sealing oil to its dehydration temperature rapidly. In the preheating zone, the oil-sealing oil has a large heat exchange area with the heat transfer oil, allowing it to be quickly heated to 80℃-100℃. In the dehydration zone, the heat transfer oil content is much higher than the oil-sealing oil content, enabling the oil-sealing oil to be heated to its dehydration temperature quickly, and the temperature of the heat transfer oil decreases more slowly. By continuously introducing heat transfer oil heated by heater 11, the temperature of the heat transfer oil in the dehydration zone can be maintained above 105℃, effectively heating the oil-sealing oil to its dehydration temperature. The heat transfer oil discharged from the dehydration zone is used to preheat the oil-sealing oil, maximizing the utilization of its heat. This partitioned structural design effectively accelerates the dehydration speed; a single cycle is sufficient to heat the oil-sealing oil to its dehydration temperature, completing the dehydration process, and achieving high energy utilization.

[0036] The connecting pipe between the third medium port 1210 and the second medium port 123 is located at the bottom of the substrate (not shown in the figure). A reinforcing screw is also provided between the two pull plates 1216, with a locking nut and a reinforcing block 1215 screwed onto the screw. The two ends of the reinforcing block 1215 abut against the two pull plates 1216 respectively to improve the stability of the pull plates 1216 and the heat exchange plate 1213. A sealing element 1220 is provided between two adjacent heat exchange plates 1213. The sealing element 1220 enhances the sealing performance between the two heat exchange plates 1213, preventing oil leakage from the heat transfer oil cavity or the oil seal cavity.

[0037] See Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the heat exchanger 12 further includes a turbulence element 1221, which is disposed on the heat exchange plate 1213. The turbulence element 1221 is spaced apart on the heat exchange plate 1213. The turbulence element 1221 disturbs the oil flow in the heat transfer oil cavity or the oil seal oil cavity, thus preventing the formation of laminar flow and enabling better heat exchange between the heat transfer oil and the oil seal oil.

[0038] In the embodiment, the turbulence member 1221 includes a transition portion 1222 and a flat portion 1223, the turbulence member 1221 is integrally formed with the heat exchange plate 1213, the transition portion 1222 can effectively reduce stress concentration in one aspect. In another aspect, the transition portion 1222 can effectively guide the oil liquid, so that the oil liquid collides in the area where the flat portion 1223 is located, thereby uniformly mixing the oil liquid and reducing the temperature gradient in the oil liquid, so that the heat transfer oil and the oil seal oil can be better heat exchanged.

[0039] Referring to Figure 3 , Figure 7 and Figure 8 In some embodiments, the heat exchanger 12 further includes a double-headed connector 129, and the third oil port 1224, the fourth oil port 1212, the third medium port 1210 and the fourth medium port 1211 are provided with the double-headed connector 129. The third oil port 1224, the fourth oil port 1212, the third medium port 1210 and the fourth medium port 1211 are connected to the corresponding pipelines through the double-headed connector 129, and the double-headed connector 129 is connected to the pipelines by clamping, bonding or screwing. Similarly, the double-headed connector 129 can also be connected to the third oil port 1224, the fourth oil port 1212, the third medium port 1210 and the fourth medium port 1211 by the above connection methods.

[0040] Referring to Figure 3 , Figure 7 and Figure 8 In some embodiments, the heat exchanger 12 further includes a second mounting plate 1225, and the pull plate 1216 is mounted to the base 121 through the second mounting plate 1225.
