[0002] The petroleum industry generally uses heated heat conduction oil to provide the required heat for various equipment such as reactors, rectifying columns, heat exchangers, etc. in the petroleum processing process, to achieve efficient heat transfer and ensure that the required temperature conditions of the process are met. The traditional process uses coal to heat heat conduction oil, which has high coal consumption and usually requires clean coal. Now, byproduct steam from other enterprises is used to exchange heat with heat conduction oil to achieve heat transfer, replacing coal for heating, thereby reducing costs.

[0003] Currently, the vertical heat conduction oil exchanger commonly used for heat transfer mainly uses a spiral pipe to perform heat transfer inside the tank body, and the outer wall area of the spiral pipe is relatively small, the heat transfer efficiency inside the tank body is relatively general, and if the heat transfer efficiency of the vertical heat exchanger can be improved, the cost can be further reduced. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes a high-efficiency vertical heat conduction oil heat exchanger, and the vertical heat conduction oil exchanger used in the related art mainly uses a spiral pipe to perform heat transfer inside the tank body, and the outer wall area of the spiral pipe is relatively small, the heat transfer efficiency inside the tank body is relatively general.

[0005] According to the high-efficiency vertical heat conduction oil heat exchanger of the present application, it comprises a storage main body part, a first heat conduction part, a second heat conduction part and a hot oil outlet part.

[0006] The storage main body part comprises a tank body and a tank cover, the tank cover covers the top of the tank body, and the bottom of the tank body is provided with a cold oil inlet pipe. The first heat conduction part comprises an air inlet pipe, a spiral pipe and a connecting pipe, the air inlet pipe and the connecting pipe are respectively communicated with both ends of the spiral pipe, and the top end of the air inlet pipe penetrates through the tank cover. The second heat conduction part comprises a lower cavity shell, an upper cavity shell and a flow guide plate, the flow guide plate is respectively communicated with the lower cavity shell and the upper cavity shell at both ends, and a plurality of groups of the upper cavity shell are located outside the spiral pipe, the bottom end of the connecting pipe is communicated with the lower cavity shell, and the top of the upper cavity shell is communicated with an air outlet pipe penetrating through the tank cover. The hot oil outlet part comprises a hot oil outlet pipe, and the bottom end of the hot oil outlet pipe penetrates through the tank cover and the upper cavity shell and is inserted into the inside of the spiral pipe.

[0007] The cold oil liquid enters the inside of the tank body from the cold oil inlet pipe at the bottom of the tank body, and is finally discharged through the hot oil outlet pipe after heat exchange. In the heat exchange process, the external steam enters the inside of the spiral pipe through the gas inlet end pipe in the first heat conduction part, and the spiral structure of the spiral pipe has a large contact area with the inside of the tank body, so that the heat is quickly conducted to the oil liquid in the inside of the tank body. The steam passing through the spiral pipe enters the lower cavity below the spiral pipe through the connecting pipe, and the steam in the inside of the lower cavity enters the inside of the upper cavity through the cavities in the plurality of guide plates on the periphery. No matter the steam is in the lower cavity, the upper cavity or the guide plate, it can conduct heat with the oil liquid in the outside tank body, especially the setting of the plurality of guide plates increases the heat conduction area of the steam and the oil liquid in the inside of the tank body, which can more efficiently exchange heat and further improve the heat exchange efficiency of the vertical heat exchanger. The steam entering the inside of the upper cavity is finally discharged from the gas outlet pipe. The steam flow direction of the high-efficiency heat-exchange vertical heat conduction oil heat exchanger is that the steam conducts heat from top to bottom through the gas inlet end pipe, the spiral pipe and the connecting pipe in the first heat conduction part, and then conducts heat from bottom to top through the lower cavity, the guide plate, the upper cavity and the gas outlet pipe, so that the oil liquid in each area of the inside of the tank body can be more uniformly heat-conducted, and the heat conduction efficiency between the steam and the oil liquid is further improved.

[0008] In some embodiments of the present application, the tank body bottom is provided with a blowdown pipe, and a valve is mounted outside the blowdown pipe.

[0009] In some embodiments of the present application, the tank cover and the upper cavity shell are both provided with first mounting holes matched with the hot oil outlet pipe.

[0010] In some embodiments of the present application, the tank cover and the upper cavity shell are both provided with second mounting holes matched with the gas inlet end pipe.

[0011] In some embodiments of the present application, the tank body top outer edge is provided with an upper edge ring plate, and the upper edge ring plate is detachably fixed and installed with the tank cover through fixing bolts.

[0012] In some embodiments of the present application, the storage main body part further comprises a sealing gasket, and the sealing gasket is arranged between the tank cover and the upper edge ring plate.

[0013] In some embodiments of the present application, the sealing gasket, the tank cover and the upper edge ring plate are all provided with through holes matched with the installation of the fixing bolts.

[0014] The high-efficiency heat-exchange vertical heat conduction oil heat exchanger further comprises a fixing frame, and the fixing frame is installed on the outer wall of the tank body.

[0015] In some embodiments of the present application, the fixing frame is provided in two groups, and the fixing frame side wall bottom is provided with a mounting port.

[0016] In some embodiments of the present application, the hot oil outlet portion further comprises a mesh cylinder, and the top end of the mesh cylinder is detachably connected with the bottom end of the hot oil outlet pipe.

[0017] The high-efficiency heat-conducting vertical heat-conducting oil heat exchanger further comprises a gas flow guide portion, the gas flow guide portion comprises a flow divider, a bearing seat and a rotating shaft, a conical cover is arranged at the bottom end of the connecting pipe and is in communication with the top wall of the lower cavity, and the conical cover is located at the upper middle part of the lower cavity, the flow divider comprises a bottom plate and a cylinder shell, an integral bottom shell is arranged at the bottom of the lower cavity, the bearing seat is arranged inside the bottom shell, the bottom end of the rotating shaft is connected with the bearing seat, the bottom plate is arranged at the bottom of the cylinder shell, the cylinder shell with a circular truncated cone structure is fixedly sleeved outside the rotating shaft, the outer wall of the cylinder shell is provided with inclined first and second leaf plates, and the first and second leaf plates are arranged at intervals, and the length of the first leaf plate is greater than that of the second leaf plate.

[0018] The steam enters into the inside of the lower cavity through the outlet pipe after passing through the inlet pipe, the spiral pipe and the connecting pipe in the first heat-conducting portion. At this time, the steam sprayed from the conical cover will be directly divided and guided through the cylinder shell with a circular truncated cone structure and the first and second leaf plates outside the cylinder shell. At the same time, the overpressure steam blown out from the conical cover will also drive the flow divider to rotate outside the rotating shaft as a whole under the action of the inclined first and second leaf plates, and the divided steam will be thrown out to the bottom end of each flow guide plate outside the lower cavity, so that the steam entering into the inside of the lower cavity from the connecting pipe and the conical cover can be more evenly dispersed into the inside of each flow guide plate, the heat exchange of the second heat-conducting portion will be more balanced, and the heat exchange efficiency between the oil and the steam is further improved. The length of the first leaf plate is greater than that of the second leaf plate, and the first and second leaf plates are arranged at intervals outside the cylinder shell, which can avoid that the area of the top of the leaf plate is too large to block the air vent at the bottom of the conical cover, so that the steam sprayed from the bottom of the conical cover can smoothly enter into the gap between the first and second leaf plates, and has a better division and guiding effect.

[0019] In some embodiments of the present application, the hot oil outlet pipe comprises an upper pipe, a lower pipe, a rotating sleeve, a threaded rod, a fine mesh plate, a threaded sleeve and a connecting block, the fine mesh plate is arranged inside the mesh cylinder, the bottom end of the lower pipe is screw-connected with the top end of the mesh cylinder, the top end of the lower pipe and the bottom end of the upper pipe are both provided with a connecting sleeve which is rotationally matched with the rotating sleeve, the bottom end of the threaded rod is rotationally connected with the fine mesh plate, the threaded sleeve is screw-connected and sleeved outside the threaded rod, and the connecting block connects the outer wall of the threaded sleeve and the inner wall of the rotating sleeve.

[0020] The original flow mode of the oil liquid of the heat conducting oil is that the oil liquid entering from the cold oil inlet pipe at the bottom of the tank body is finally discharged from the heat oil outlet pipe piece above the mesh cylinder through the mesh cylinder. The larger mesh hole outside the mesh cylinder can only coarsely filter the larger impurities in the oil liquid. The rotating sleeve in the rotating heat oil outlet pipe piece is driven to rotate by the connecting block, and the rotating sleeve drives the threaded sleeve inside to rotate. Since the threaded sleeve is provided with internal threads matched with the threaded rod, the rotating threaded sleeve drives the threaded sleeve to move upward, that is, the fine sieve plate at the bottom of the threaded rod moves upward, and the fine sieve plate moves to the bottom end of the lower pipe inside the mesh cylinder. At this time, the oil liquid entering the tank body from the cold oil inlet pipe is preliminarily coarsely filtered by the mesh cylinder, and then finely filtered by the fine sieve plate, so that the impurities in the heat conducting oil can be better cleaned. Moreover, when the impurities in the oil liquid in the heat conducting oil are less, the flow rate of the heat conducting oil discharged from the upper pipe can also be adjusted. That is, the rotating sleeve drives the threaded sleeve to rotate, and the rotating threaded sleeve drives the fine sieve plate to move inside the mesh cylinder to adjust the height through the cooperation of the threaded rod. At this time, the oil liquid entering the cold oil inlet pipe inside the cold oil inlet pipe can directly enter the lower pipe and the upper pipe from the mesh hole outside the mesh cylinder above the fine sieve plate, and the oil liquid entering the mesh hole outside the mesh cylinder below the fine sieve plate needs to pass through the fine sieve plate before entering the lower pipe and the upper pipe. Since the mesh hole on the fine sieve plate is more dense, the flow rate of the oil liquid entering the lower pipe through the fine sieve plate will decrease, that is, by adjusting the height of the fine sieve plate inside the mesh cylinder, the flow rate of the oil liquid discharged from the upper pipe is adjusted. When the heat exchanger stops running, the rotating sleeve adjusts the fine sieve plate to block at the bottom end of the lower pipe. Open the valve to pressurize the oil liquid from the upper pipe and back flush, and the high-pressure oil liquid back flushes the fine sieve plate and the mesh cylinder through the upper pipe and the lower pipe, so that the impurities remaining in the fine sieve plate and the mesh hole of the mesh cylinder are back flushed and cleaned, and the cleaned impurities are finally discharged through the blowdown pipe.

[0021] The beneficial effects of the present application are: the high-efficiency vertical heat conducting oil heat exchanger obtained by the above design, the cold oil liquid enters the tank body from the cold oil inlet pipe at the bottom of the tank body, and is finally discharged through the heat oil outlet pipe piece after heat exchange. During heat exchange, the external steam enters the spiral pipe inside through the inlet pipe in the first heat conducting part, and the spiral structure of the spiral pipe itself has a large contact area with the inside of the tank body, quickly conducting heat to the oil liquid inside the tank body. The steam passing through the spiral pipe enters the lower chamber below the spiral pipe through the connecting pipe, and the steam inside the lower chamber enters the upper chamber inside through the cavities in the multiple guide plates on the periphery. Whether the steam is inside the lower chamber, the upper chamber or the guide plate, it can conduct heat with the oil liquid in the external tank body, especially the multiple guide plates, which increase the heat conduction area of the steam and the oil liquid inside the tank body, can more efficiently exchange heat, and further improve the heat exchange efficiency of the vertical heat exchanger.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0039] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0040] A high-efficiency heat exchange vertical heat conducting oil heat exchanger according to an embodiment of the present application is described below with reference to the drawings.

[0041] Please refer to Figures 1-11 A high-efficiency heat exchange vertical heat conducting oil heat exchanger according to an embodiment of the present application includes a storage main body part 10, a first heat conducting part 20, a second heat conducting part 30, and a hot oil outlet part 40.

[0042] The oil liquid is heated rapidly by steam in the storage main body part 10 through the first heat conduction part 20 and the second heat conduction part 30, compared with the traditional single heat exchange mode of the spiral pipe, the high-efficiency heat exchange vertical heat conduction oil heat exchanger can increase the heat exchange area and improve the overall heat exchange efficiency of the heat exchanger.

[0043] Please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 9 , the storage main body part 10 includes a tank body 110 and a tank cover 120. The tank cover 120 is covered on the top of the tank body 110, and the bottom of the tank body 110 is provided with a cold oil inlet pipe 130. The first heat conduction part 20 includes an air inlet end pipe 210, a spiral pipe 220 and a connecting pipe 230. The air inlet end pipe 210 and the connecting pipe 230 are respectively communicated with the two ends of the spiral pipe 220, and the top end of the air inlet end pipe 210 penetrates the tank cover 120. The second heat conduction part 30 includes a lower cavity shell 310, an upper cavity shell 320 and a flow guide plate 330. The two ends of the flow guide plate 330 are respectively communicated with the lower cavity shell 310 and the upper cavity shell 320, and a plurality of upper cavity shells 320 are located outside the spiral pipe 220. The bottom end of the connecting pipe 230 is communicated with the lower cavity shell 310, and the top of the upper cavity shell 320 is communicated with an air outlet pipe 340 penetrating the tank cover 120. The hot oil outlet part 40 includes a hot oil outlet pipe 410, and the bottom end of the hot oil outlet pipe 410 penetrates the tank cover 120 and the upper cavity shell 320 and is inserted into the inside of the spiral pipe 220.

[0044] The working principle of the high-efficiency heat exchange vertical heat conduction oil heat exchanger is as follows: the cold oil liquid enters into the inside of the tank body 110 from the cold oil inlet pipe 130 at the bottom of the tank body 110, and is finally discharged through the hot oil outlet pipe 410 after heat exchange. In the heat exchange process, the external steam enters into the inside of the spiral pipe 220 through the air inlet end pipe 210 in the first heat conduction part 20, and the spiral structure of the spiral pipe 220 has a large contact area with the inside of the tank body 110, so that the heat is quickly conducted into the oil liquid in the inside of the tank body 110. The steam passing through the spiral pipe 220 enters into the lower cavity shell 310 below the spiral pipe 220 through the connecting pipe 230, and the steam in the inside of the lower cavity shell 310 enters into the inside of the upper cavity shell 320 through the cavities in the plurality of flow guide plates 330 on the periphery. The steam in the lower cavity shell 310, the upper cavity shell 320 or the flow guide plate 330 can conduct heat with the oil liquid in the outside tank body 110, especially the plurality of flow guide plates 330 increase the heat conduction area of the steam and the oil liquid in the inside of the tank body 110, so that the heat can be exchanged more efficiently, and the heat exchange efficiency of the vertical heat exchanger is further improved. The steam entering into the inside of the upper cavity shell 320 is finally discharged from the air outlet pipe 340.

[0045] The steam flow direction of the high-efficiency heat exchange vertical heat conducting oil heat exchanger is that the steam conducts heat from top to bottom through the inlet pipe 210, the spiral pipe 220 and the connecting pipe 230 in the first heat conducting part 20, and then conducts heat from bottom to top through the lower cavity 310, the guide plate 330, the upper cavity 320 and the outlet pipe 340, so that the oil in each area inside the tank body 110 can be more uniformly heat-conducted, and the heat conduction efficiency between the steam and the oil is further improved.

[0046] In the specific setting, please refer to Figure 1 The tank body 110 is provided with a blowdown pipe 140 at the bottom, and a valve 150 is installed outside the blowdown pipe 140. In long-term use, impurities may be left inside the tank body 110. By opening the valve 150 outside the blowdown pipe 140, the impurities inside the tank body 110 can be discharged along the blowdown pipe 140 at the bottom of the tank body 110.

[0047] Specifically, please refer to Figure 4 The tank cover 120 and the upper cavity 320 are both provided with a first mounting hole 121 which is penetrated by the hot oil outlet pipe 410. The hot oil outlet pipe 410 is fixed and sealed between the tank cover 120 and the tank body 110 by welding, and the gap between the hot oil outlet pipe 410 and the first mounting hole 121 is sealed. The tank cover 120 and the upper cavity 320 are both provided with a second mounting hole 122 which is penetrated by the inlet pipe 210. The inlet pipe 210 is fixed and sealed between the tank cover 120 and the upper cavity 320 by welding, and the gap between the inlet pipe 210 and the second mounting hole 122 is sealed.

[0048] Further, please refer to Figure 2 and Figure 4 The tank body 110 is provided with an upper ring plate 160 outside the top. The tank body 110 and the upper ring plate 160 can be integrally formed. The tank cover 120 is detachably fixed and installed on the tank body 110 by the fixing bolt 180. The storage main body part 10 further comprises a sealing gasket 170 which is arranged between the tank cover 120 and the upper ring plate 160. The sealing gasket 170, the tank cover 120 and the upper ring plate 160 are all provided with through holes which are matched with the fixing bolt 180. The tank cover 120 and the tank body 110 can be detached by the fixing bolt 180. When the tank cover 120 is detached, the hot oil outlet pipe 410 and the inlet pipe 210 are both welded to the tank cover 120, so that the tank cover 120, the second heat conducting part 30 and the hot oil outlet part 40 are taken out of the tank body 110 together when the tank cover 120 is taken out.

[0049] In the above specific embodiments, please refer to Figure 1 and Figure 3The high-efficiency heat exchange vertical heat conducting oil heat exchanger further comprises a fixing frame 50 installed on the outer wall of the tank body 110, and the fixing frame 50 and the tank body 110 can be fixed by welding.

[0050] In the specific setting, please refer to Figure 9 The hot oil outlet part 40 further comprises a mesh tube 420, and the mesh tube 420 is detachably installed by screwing the top end of the mesh tube 420 with the bottom end of the hot oil outlet pipe 410. The mesh holes on the mesh tube 420 can filter out larger impurities in the oil, and the filtered impurities will be deposited at the bottom of the tank body 110. By opening the valve 150 outside the blowdown pipe 140, the impurities deposited in the tank body 110 can be discharged from the blowdown pipe 140.

[0051] After the steam passes through the lower cavity shell 310, the spiral pipe 220 and the connecting pipe 230 into the inside of the lower cavity shell 310, the steam in the inside of the lower cavity shell 310 is difficult to enter the cavity of each guide plate 330 uniformly, which will affect the dispersion and heat conduction effect of the steam. Moreover, the gas outlet pipe 340 cannot be arranged at the middle part of the upper cavity shell 320, causing the distance between the top outlet of each guide plate 330 and the gas outlet pipe 340 to be different, which will further affect the uniform diffusion of the steam in the inside of the lower cavity shell 310 to the surrounding guide plates 330.

[0052] Please refer to Figure 6 、 Figure 7 and Figure 8 The high-efficiency heat exchange vertical heat conducting oil heat exchanger further comprises a gas flow guiding part 60, which comprises a flow dividing piece 610, a bearing seat 620 and a rotating shaft 630. The bottom end of the connecting pipe 230 is provided with a conical cover 240 in communication with the top wall of the lower cavity shell 310, and the conical cover 240 is located above the middle part of the lower cavity shell 310. The flow dividing piece 610 comprises a bottom plate 611 and a cylinder shell 612. The bottom of the cylinder shell 612 is provided with a bottom shell 350, the bearing seat 620 is installed in the inside of the bottom shell 350, and the bottom end of the rotating shaft 630 is connected with the bearing seat 620. The bottom plate 611 is arranged at the bottom of the cylinder shell 612, the cylinder shell 612 in the circular table structure is fixedly sleeved outside the rotating shaft 630, the outer wall of the cylinder shell 612 is provided with inclined first and second leaf plates 613 and 614, the first and second leaf plates 613 and 614 are spaced apart, and the length of the first leaf plate 613 is greater than that of the second leaf plate 614. Among them, the bottom plate 611, the cylinder shell 612, the first leaf plate 613 and the second leaf plate 614 can be integrally formed.

[0053] Steam through the first heat-conducting part 20 in the gas inlet end tube 210, spiral tube 220, connecting tube 230 after through the gas outlet tube 340 into the lower cavity shell 310 inside. At this time from the conical shell 240 spouted steam will be directly through the circular table structure of the cylinder shell 612 and its outside the first leaf plate 613 and the second leaf plate 614 for diversion. At the same time, the overpressure steam blown from the conical shell 240 will also be driven by the inclined first leaf plate 613 and the second leaf plate 614 under the action of the whole diversion piece 610 rotating outside the shaft 630, the diverted steam will be thrown to the bottom end of each guide plate 330 outside the lower cavity shell 310, realizing that the steam entering the lower cavity shell 310 from the connecting tube 230 and the conical shell 240 can be more evenly dispersed into each guide plate 330 inside, the heat exchange of the second heat-conducting part 30 will be more balanced, further improving the heat exchange efficiency between the oil and the steam.

[0054] Among them, the leaf plate length of the first leaf plate 613 is longer than the leaf plate length of the second leaf plate 614, and the first leaf plate 613 and the second leaf plate 614 are staggered outside the cylinder shell 612. This design can avoid the area of the top of the leaf plate being too large to block the air port at the bottom of the conical shell 240, so that the steam spouted from the bottom of the conical shell 240 can smoothly enter the gap between the first leaf plate 613 and the second leaf plate 614, having a better diversion effect.

[0055] During the long-term heat cycle of the oil liquid of the heat-conducting oil, the impurities deposited in the inner wall of the tube wall will enter the tank body 110 inside along with the heat-conducting oil. The mesh cylinder 420 at the bottom of the heat oil outlet pipe 410 can coarsely filter the larger impurities in the oil liquid, but cannot filter the smaller impurities in the oil liquid and quickly clean the impurities on the filter screen.

[0056] In the above specific embodiments, please refer to Figure 9 , Figure 10 and Figure 11 , the heat oil outlet pipe 410 includes an upper pipe 411, a lower pipe 412, a rotating sleeve 413, a threaded rod 414, a fine mesh screen plate 415, a threaded sleeve 417 and a connecting block 418. The fine mesh screen plate 415 is located inside the mesh cylinder 420, the lower pipe 412 is screw-connected with the top end of the mesh cylinder 420, the top end of the lower pipe 412 and the bottom end of the upper pipe 411 are provided with a connecting sleeve 416 rotatingly matched with the rotating sleeve 413, the bottom end of the threaded rod 414 is rotationally connected with the fine mesh screen plate 415, the threaded sleeve 417 is screw-connected outside the threaded rod 414, and the connecting block 418 connects the outer wall of the threaded sleeve 417 and the inner wall of the rotating sleeve 413.

[0057] The original flow mode of the oil liquid of the heat conducting oil is that the oil liquid entering from the cold oil inlet pipe 130 at the bottom of the tank body 110 passes through the mesh cylinder 420 and is finally discharged from the hot oil outlet pipe 410 above the mesh cylinder 420. The larger mesh holes outside the mesh cylinder 420 can only coarsely filter larger impurities in the oil liquid. The rotating sleeve 413 in the rotating hot oil outlet pipe 410 drives the threaded sleeve 417 inside the connecting block 418 to rotate. Since the threaded sleeve 417 is internally provided with an internal thread matched with the threaded rod 414, the rotating threaded sleeve 417 drives the threaded sleeve 417 to move upwards, that is, the fine mesh plate 415 at the bottom of the threaded rod 414 moves upwards, until the fine mesh plate 415 moves to the bottom end of the lower pipe 412 inside the mesh cylinder 420. At this time, the oil liquid entering the tank body 110 from the cold oil inlet pipe 130 is preliminarily filtered by the mesh cylinder 420, and then is finely filtered by the fine mesh plate 415, so that the impurities in the heat conducting oil can be better cleaned.

[0058] And the design can also adjust the flow rate of the heat conducting oil discharged from the upper pipe 411 when there are fewer impurities in the oil liquid in the heat conducting oil. That is, rotating the rotating sleeve 413 drives the threaded sleeve 417 to rotate, and the rotating threaded sleeve 417 drives the fine mesh plate 415 to move inside the mesh cylinder 420 to adjust the height through the cooperation of the threaded rod 414. At this time, the oil liquid entering the cold oil inlet pipe 130 from the cold oil inlet pipe 130 can directly enter the lower pipe 412 and the upper pipe 411 inside from the mesh holes outside the mesh cylinder 420 above the fine mesh plate 415, and the oil liquid entering the mesh holes outside the mesh cylinder 420 below the fine mesh plate 415 needs to pass through the fine mesh plate 415 before entering the lower pipe 412 and the upper pipe 411. Since the mesh holes on the fine mesh plate 415 are more dense, the flow rate of the oil liquid entering the lower pipe 412 through the fine mesh plate 415 will decrease, that is, by adjusting the height of the fine mesh plate 415 inside the mesh cylinder 420, the flow rate of the oil liquid discharged from the upper pipe 411 is adjusted.

[0059] When the heat exchanger stops running, the rotating sleeve 413 adjusts the fine mesh plate 415 to block at the bottom end of the lower pipe 412. Open the valve 150 to pressurize and backflush the oil liquid from the upper pipe 411. The high-pressure oil liquid backflushes the fine mesh plate 415 and the mesh cylinder 420 through the upper pipe 411 and the lower pipe 412, so that the impurities remaining in the fine mesh plate 415 and the mesh holes of the mesh cylinder 420 are backflushed and cleaned. The cleaned impurities are finally discharged through the blowdown pipe 140.
