Abstract
Description
Technical Field
[0001] The present application relates to the technical field of heat exchangers, and in particular to a high-efficiency heat exchanger for petrochemical industry. Background Art
[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.
[0003] When a chemical heat exchanger is working, hot fluid is usually continuously put into the shell side, and chemical petroleum raw materials that need heat exchange treatment are put into the tube side. Heat exchange treatment is carried out through the circulation of petroleum raw materials and heat medium. In order to ensure that the petroleum raw materials and heat medium can effectively exchange heat, baffles are usually set in the shell side. Through the guidance of the baffles, the flow path of the heat medium in the shell side of the heat exchanger is extended, the residence time of the heat medium in the shell side is increased, and the heat transfer area of the heat medium to the tube side is increased to improve the heat exchange efficiency.
[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: only setting baffles in the shell side of the heat exchanger cannot guide the uniform distribution of the crude oil in the tube side, so that the crude oil will form a laminar flow or uneven flow in the tube side, so that some heat exchange tubes fail to fully exert their heat transfer capacity, resulting in a reduction in the contact area between the crude oil and the inner wall of the heat exchange tube, which is not conducive to the effective transfer of heat in the tube side, thereby reducing the heat transfer efficiency of the crude oil, and long-term use will cause the heat exchange tube to be unevenly heated and generate thermal stress. Long-term thermal stress will cause the heat exchange tube to deform, crack or fail, reducing the service life of the heat exchanger; After long-term use of the heat exchanger, the heat exchange tubes and heat exchange shells will usually be ruptured and pits will appear on the heat exchange shell wall due to the erosion of petroleum raw materials and heat media. Therefore, the heat exchanger needs to be disassembled and repaired regularly. However, the ruptures of the heat exchange tubes and the pits of the heat exchange shell are usually very small, and it is difficult to find them during disassembly inspection. Therefore, it takes a lot of time for the staff to detect and search, which increases the labor intensity of the staff. Summary of the invention
[0005] In order to solve the problem that only setting baffles in the shell side of the heat exchanger cannot guide the uniform distribution of the petroleum raw materials in the tube side, causing the petroleum raw materials to form laminar flow or uneven flow in the tube side, the present application provides a high-efficiency heat exchanger for petrochemical industry.
[0006] The present application provides a high-efficiency heat exchanger for petrochemical industry using the following technical solution: A high-efficiency heat exchanger for petrochemical industry, comprising a heat exchange shell, a corrosion inhibition box fixed on the heat exchange shell, a plurality of heat exchange tubes and two baffles rotatably arranged on the heat exchange shell, a processing mechanism for scraping, crack detection and marking the plurality of heat exchange tubes, a rotating assembly for rotating the plurality of heat exchange tubes, a translation assembly for translationally driving the two baffles, and a testing assembly for deformation detection of the inner wall of the heat exchange shell; The corrosion inhibitor box is used to store the corrosion inhibitor, and the heat exchange shell is provided with a control component for controlling the release amount of the corrosion inhibitor; The test assembly includes a second marking pen rotatably disposed on the baffle plate and a power member for driving the second marking pen to translate; The translation assembly includes two baffles rotatably arranged in the heat exchange shell and a translation member for driving the two baffles to translate respectively; The processing mechanism includes a scraping and brushing assembly, a detection assembly and a marking assembly, wherein the scraping and brushing assembly includes baffle frames movably arranged on a plurality of heat exchange tubes and a scraping and brushing member for driving the plurality of baffle frames to translate; The detection assembly includes detection rings movably disposed on a plurality of heat exchange tubes, first sensors fixed in the plurality of detection rings, discharge plates movably disposed on the plurality of detection rings, induction members for inductively driving the first sensors, and moving members for translationally driving the discharge plates; The marking assembly includes a first marking pen rotatably arranged on a plurality of detection rings and a swinging member for swingingly driving the first marking pen; The control assembly includes two discharge pipes fixed on the corrosion inhibition box, control plates movably arranged on the two discharge pipes, and control members for driving the two control plates to translate respectively; The heat exchange shell is also provided with a synchronization member for synchronously driving the scraping member and the translation member, and a disassembly member for disassembling and assembling the heat exchange tube; The swinging member includes two ejection springs fixed on the detection ring and two adjustment frames rotatably arranged on the detection ring. The first marking pen is fixedly connected to the adjustment frame, the two ejection springs are respectively fixedly connected to the two adjustment frames, and the two adjustment frames are both hinged to the detection ring.
[0007] By adopting the above technical scheme, the scraping and brushing components, the detection components and the marking components in the processing mechanism directly cooperate to detect the rupture of multiple heat exchange tubes respectively, mark the position of the rupture of the heat exchange tubes, and scrape and brush multiple heat exchange tubes at the same time, and ensure the effect of heat transfer of the heat medium in the shell of the heat exchange shell. The rotating component can drive the multiple heat exchange tubes to rotate, and can roll and stir the heat medium in the heat exchange shell and the petroleum raw materials in the multiple heat exchange tubes, which can enhance the effect of the tumbling of the heat medium on the inner side of the heat exchange shell and enhance the efficiency of heat exchange between the petroleum raw materials and the heat medium. At the same time, the translation component, the test component and the scraping and brushing component can be driven. The translation component can scrape and brush the outer sides of multiple heat exchange tubes in multiple ranges and detect ruptures. The test component can scrape and brush the inner wall of the heat exchange shell in multiple ranges and detect deformation. The control component can quantitatively add corrosion inhibitors to the petroleum raw materials and the heat medium, and can automatically control the amount of corrosion inhibitors according to the amount of the petroleum raw materials and the heat medium, so as to avoid scaling and stains on the heat exchange shell and multiple heat exchange tubes as much as possible. Petroleum raw materials have a certain viscosity and flow in the pipe for a long time. Some of the petroleum raw materials will adhere to the inner wall of the heat exchange tube. Therefore, the heat exchanger needs to be disassembled and cleaned regularly to prevent the petroleum raw materials from forming sediments and salt scales that adhere to the heat exchange tube wall and pollute the heat exchange tube wall, thereby corroding and rupturing the heat exchange tube and affecting its heat transfer efficiency. However, this method requires regular and frequent disassembly and cleaning of the heat exchanger. The disassembly and cleaning process of the heat exchanger is relatively complicated, which will increase the workload of the staff. In addition, it is difficult to control the tightness of the heat exchanger if it is frequently assembled. Over-tight assembly will cause damage to the metal plate or gasket. Insufficient tightness will cause leakage of petroleum raw materials and heat medium. In addition, if the staff forgets to clean the heat exchanger regularly, sediments and salt scales will accumulate on the inner wall of the heat exchange tube, making it difficult to clean the sediments and salt scales on the inner wall of the heat exchange tube in the subsequent sequence. Forced cleaning will cause scratches, wear and rupture on the inner wall of the heat exchange tube, affecting the performance and service life of the heat exchange tube. Frequent disassembly and cleaning of the heat exchanger. The disassembly and cleaning process of the heat exchanger is relatively complicated, which will increase the workload of the staff. In addition, it is difficult to control the tightness of the frequent assembly of the heat exchanger. Over-tight assembly will cause damage to the metal plate or gasket. Insufficient tightness will cause leakage of oil raw materials and heat medium. If the staff forgets to clean the heat exchanger regularly, the sediment and salt scale on the inner wall of the heat exchange tube will accumulate, making it difficult to clean the sediment and salt scale on the inner wall of the heat exchange tube in the subsequent sequence. Forced cleaning will cause scratches, wear and rupture on the inner wall of the heat exchange tube, affecting the performance and service life of the heat exchange tube; The heat exchanger tubes and shells will be corroded and damaged due to the erosion of petroleum raw materials and heat media after long-term use. If corrosion inhibitors are not added to the petroleum raw materials and heat media, the speed of erosion of the heat exchange tubes and shells by the petroleum raw materials and heat media will be accelerated, causing the heat exchange tubes and shells to often be cracked and pitted, and the heat exchanger needs to be frequently disassembled for inspection and maintenance. Therefore, in order to avoid corrosion of the heat exchanger shell and tube caused by petroleum raw materials and heat media, corrosion inhibitors need to be added to the petroleum raw materials and heat media to slow down the corrosion of the shell and tube caused by petroleum raw materials and heat media, reduce the frequency of heat exchanger disassembly, inspection and maintenance, and try to avoid The seal of the heat exchanger is affected by frequent disassembly, but currently the corrosion inhibitor is usually added directly to the petroleum raw material and the heat medium. Although this adding method is convenient, it is not convenient to control the amount of corrosion inhibitor added according to the amount of petroleum raw material and the heat medium. If the amount of petroleum raw material and the heat medium is too much, and the amount of corrosion inhibitor added is too little, it will lead to insufficient corrosion inhibition effect on the shell and the pipe, and sediment will still form. If the amount of petroleum raw material and the heat medium is too little, the amount of corrosion inhibitor added is too much, which will cause unnecessary cost waste, and excessive corrosion inhibitor will have adverse effects on petroleum raw materials and heat medium, and increase the generation of sediment; The power part can drive the second marking pen to mark the position of the pit on the inner wall of the heat exchange shell, so that the staff can quickly know the position of the pit inside the heat exchange shell for maintenance. The translation part can drive the two baffles to move left and right on multiple heat exchange tubes, and can perform multi-range scraping and inspection on the outside of multiple heat exchange tubes. The scraping and brushing part can drive multiple baffle frames to move left and right in multiple heat exchange tubes respectively, and can scrape and brush the inner walls of multiple heat exchange tubes, and can ensure the baffle heat transfer effect of petroleum raw materials in multiple heat exchange tubes. The induction part can let the staff know that the heat exchange tube is broken and needs to be repaired, and can let the staff know that the heat exchange tube is broken and needs to be repaired. The operator knows which heat exchange tube is broken and needs to be repaired. The swinging part can drive the first marking pen to swing and mark the position of the broken heat exchange tube, so that the operator can quickly know the position of the broken heat exchange tube for repair. The moving part can release the leaked oil raw material in the detection ring to return the first marking pen to the initial state to avoid the first marking pen from continuously fitting and marking the heat exchange tube. The control part can adjust the outlet size of the two discharge pipes and can add a specified amount of corrosion inhibitor according to the amount of oil raw material and heat medium. The synchronous part can synchronously drive the scraping part and the translation part. The disassembly part can disassemble and repair the specified damaged heat exchange tube. Since the two adjustment frames are hinged to the detection ring, the two adjustment frames will be pushed to swing when the sensing element is driven, so that the two compression springs will be stretched. Therefore, when the two adjustment frames swing, they can respectively drive the two first marking pens to swing. When the two first marking pens swing, the heat exchange tube can be marked, which indicates that there is a crack on the heat exchange tube, and the position of the crack is between the two first marking pens. Therefore, the staff can quickly know the position of the crack in the heat exchange tube without the need for the staff to search laboriously. The position of the heat exchange tube that needs to be repaired can be quickly found, thereby improving the speed of heat exchange tube repair.

[0009] By adopting the above technical scheme, the heat medium will impact on the two hydraulic racks when flowing in the oil inlet pipe and the liquid outlet pipe, driving the two hydraulic racks to rotate clockwise, which can respectively drive two transmission gears, two power gears, two partition plates, multiple heat exchange tubes, two baffles and two groups of baffle racks to rotate on the heat exchange shell, so that the heat medium in the heat exchange shell and the petroleum raw materials in the multiple heat exchange tubes can be tumbled and stirred, and the tumbling effect of the heat medium on the inside of the heat exchange shell can be enhanced. At the same time, the positions of the multiple heat exchange tubes can be adjusted so that the outer surfaces of the multiple heat exchange tubes can be evenly in contact with the heat medium, the inner surfaces of the multiple heat exchange tubes can be evenly in contact with the petroleum raw materials, and the petroleum raw materials on the inside of the multiple heat exchange tubes can be evenly in contact with the heat medium for heat exchange.

[0011] By adopting the above technical solution, when the two partition plates rotate, they will also drive the two second bidirectional screws and the two sets of connecting gears to rotate in a circle. The two internal gears can respectively drive the two sets of connecting gears and the two second bidirectional screws to rotate on their own, and can respectively drive the two baffles and the multiple detection rings to move left and right on the multiple heat exchange tubes. The left and right movement of the two baffles and the multiple detection rings can be used to scrape the outer sides of the multiple heat exchange tubes and the inner side of the heat exchange shell to prevent stains and particles of the heat medium from sticking to the outer sides of the heat exchange tubes and the inner sides of the heat exchange shell, thereby enhancing the effect of uniform heat exchange of the heat medium on the outer surfaces of the multiple heat exchange tubes.

[0013] By adopting the above technical scheme, when the two partition plates rotate, they will also drive the two groups of first bidirectional screws and two groups of movable gears to rotate in a circle. The two internal gears can respectively drive the two groups of movable gears and the two groups of first bidirectional screws to rotate on their own. Then, while the two groups of first bidirectional screws rotate on their own, they can respectively drive the two fixed rings, two groups of connecting frames and two groups of baffle frames to move left and right on the inner sides of multiple heat exchange tubes respectively. By scraping the inner sides of multiple heat exchange tubes through the left and right movement of the two groups of baffle frames, stains and particles of petroleum raw materials can be prevented from sticking to the inner sides of the heat exchange tubes. At the same time, when the two groups of baffle frames move left and right in the multiple heat exchange tubes, the effect of baffle of petroleum raw materials in the heat exchange shell and tube process can be enhanced.
[0014] Optionally, the sensing component includes adjusting blocks movably arranged on the multiple detection rings, annular springs fixed on the multiple adjustment blocks, sealing rings fixed on the multiple detection rings, and an alarm fixed on the heat exchange shell; the multiple detection rings are each provided with a heat exchange hole equal to the diameter of the heat exchange tube; the multiple detection rings are each provided with a detection cavity; the multiple adjustment blocks are movably fitted with the multiple first sensors, the multiple first sensors are electrically connected to the alarm; the multiple sealing rings are respectively located in the multiple heat exchange holes; the multiple heat exchange tubes are respectively slidably connected with the multiple sealing rings; the multiple annular springs are respectively fixedly connected with the multiple detection rings; the number of the multiple detection rings is divided into two groups; the two groups of detection rings are respectively fixedly connected with two baffles; and the two adjustment frames are movably fitted with the adjusting blocks.
[0015] By adopting the above technical solution, multiple detection rings can move left and right on multiple heat exchange tubes respectively, and can detect the rupture of multiple heat exchange tubes respectively. When the heat exchange tube is ruptured, the detection ring moves left and right on the outside of the heat exchange tube, and the petroleum raw materials in the heat exchange tube will flow into the detection cavity in the detection ring through the crack of the heat exchange tube. Filling the detection cavity will squeeze and push the adjustment block, so that the annular spring is in a compressed state, which can drive the adjustment block to move. When the adjustment block moves, it will contact with the first sensor and be triggered, and then the first sensor will transmit the signal to the alarm to alarm, which can remind the staff that the heat exchange tube is ruptured and needs to be repaired or replaced. At the same time, according to the triggered first sensor, the staff can know which heat exchange tube is ruptured.
[0016] Optionally, the movable part includes a second wedge block movably arranged in the detection ring, a third wedge block fixed on a plurality of second wedge blocks, a connecting rod fixed on a plurality of discharge plates, a first spring and a connecting pipe fixed on a plurality of detection rings, and a second spring and a one-way valve fixed on a plurality of connecting pipes, a plurality of the first springs are fixedly connected to a plurality of third wedge blocks, a plurality of the second springs are fixedly connected to a plurality of connecting rods, a plurality of the connecting rods are movably fitted with the inclined surfaces of a plurality of third wedge blocks, and a plurality of the adjustment blocks are movably fitted with the inclined surfaces of a plurality of second wedge blocks.
[0017] By adopting the above technical solution, when the adjusting block moves, it will push the second wedge block to move, so that the first spring is squeezed and then the third wedge block can be pushed to move. When the third wedge block moves, the elastic force of the second spring can adjust the position of the connection rod and the third wedge block to fit and contact each other, and then the connection rod and the discharge plate can be driven to move in turn, so that the discharge plate can open the connecting pipe, and the petroleum raw materials in the detection chamber can be released through the connecting pipe, so that the adjusting block can be restored to its initial state. Through the elastic force of the annular spring and the two compression springs, the two adjusting frames and the two first marking pens can also be restored to their initial states, so as to avoid the two first marking pens continuously contacting and marking the heat exchange tubes after marking the heat exchange tubes.
[0018] Optionally, the power component includes a second sensor and a coil spring respectively fixed on the two baffles, a connecting block respectively fixed on the two coil springs, and a movable rod respectively fixed on the two connecting blocks, the two coil springs are respectively fixedly connected to the two connecting blocks, the two connecting blocks are respectively fixedly connected to the two second marking pens, the two movable rods are both movably connected to the heat exchange shell, the two second sensors are respectively movably fitted to the two connecting blocks, and the two second sensors are both electrically connected to the alarm.
[0019] By adopting the above technical solution, when the two baffles move, they will also drive the two moving rods, the two connecting blocks and the two second marking pens to move, and then the two moving rods can detect the inner wall of the heat exchange shell when they move. When there is a pit on the inner side of the heat exchange shell, the elastic force of the coil spring can drive the moving rod and the second marking pen to move in turn, and when the moving rod moves to the pit, the second marking pen can mark the side of the pit, so that the staff can quickly know the position of the pit of the heat exchange shell. At the same time, when the moving rod detects the pit and moves, it will contact and trigger the second sensor, and then the second sensor will transmit the signal to the alarm to alert the staff that there is a pit in the heat exchange shell and it needs to be disassembled and repaired, so as to avoid the heat exchange shell from being broken due to continuous use.
[0020] Optionally, the control component includes an oil inlet pipe and an oil outlet pipe fixed on the heat exchange shell, wedge-shaped adjustment blocks movably arranged on the liquid inlet pipe and the oil inlet pipe, first wedge blocks fixed on the two wedge-shaped adjustment blocks, movable rods fixed on the two control plates, telescopic springs fixed on the two outlet pipes, and connecting springs fixed on the liquid inlet pipe and the oil inlet pipe, the two telescopic springs are fixedly connected to the two movable rods, the two connecting springs are fixedly connected to the two first wedge blocks, the two movable rods are movably fitted with the inclined surfaces of the two first wedge blocks, and the two outlet pipes are connected to the liquid inlet pipe and the oil inlet pipe, respectively.
[0021] By adopting the above technical scheme, when the heat medium and the petroleum raw material flow in the liquid inlet pipe and the oil inlet pipe respectively, the pressure of the heat medium and the petroleum raw material in the liquid inlet pipe and the oil inlet pipe can be detected by the two wedge-shaped adjustment blocks. When the heat medium and the petroleum raw material flush the two wedge-shaped adjustment blocks respectively, the two connecting springs are compressed and then drive the two first wedge blocks to move respectively. The elastic force of the two telescopic springs can be adjusted to adjust the position of the two movable rods and the two first wedge blocks to fit and contact respectively, and the two movable rods and the two control plates can be driven to move respectively, so that the two control plates open the two discharge pipes respectively, and the corrosion inhibitor in the corrosion inhibition box will be put into the liquid inlet pipe and the oil inlet pipe respectively through the two discharge pipes, so that the corrosion inhibitor is separated and the oil inlet pipe is opened. The heat medium and petroleum raw materials are mixed, so that the corrosion inhibitor is added to the heat medium, which can slow down the corrosion of the heat medium on the inner wall of the heat exchange shell and the outer sides of multiple heat exchange tubes. Adding the corrosion inhibitor to the petroleum raw materials can slow down the corrosion of the inner wall of the heat exchange shell and the inner walls of multiple heat exchange tubes by the petroleum raw materials. Through the moving range of the two wedge-shaped adjustment blocks and the pressure of the two connecting springs, the more the pressure feeding amount of the heat medium and the petroleum raw materials is, the more the corrosion inhibitor is released from the two discharge pipes. The smaller the pressure feeding amount of the heat medium and the petroleum raw materials is, the smaller the openings of the two discharge pipes are, and the less the corrosion inhibitor is released from the two discharge pipes. The amount of corrosion inhibitor added can be automatically controlled according to the feeding amount of the heat medium and the petroleum raw materials.
[0022] Optionally, the disassembly and assembly parts include two heat exchange covers movably arranged on the heat exchange shell and two groups of support rods and two groups of rolling bearings rotatably arranged in the heat exchange shell, the two heat exchange covers are connected to the heat exchange shell through connecting bolts, the inner side of the left partition plate is provided with a plurality of first convex holes, the inner side of the right partition plate is provided with a plurality of second convex holes, the plurality of heat exchange tubes are movably fitted with the plurality of first convex holes, the plurality of heat exchange tubes are movably fitted with the plurality of second convex holes, the plurality of heat exchange tubes are connected to the two partition plates through connecting screws, the number of each group of support rods and each group of rolling bearings is two, the four support rods are movably connected with the four first bidirectional screws, the four support rods are fixedly connected with the four rolling bearings, the two groups of rolling bearings are fixedly connected with the two partition plates, and the support rods and the first bidirectional screws are movably connected through movable bolts.
[0023] By adopting the above technical solution, when it is necessary to disassemble and repair the designated heat exchange tube, the two heat exchange covers on the heat exchange shell are disassembled first. The first bidirectional screw rod and the support rod are connected by movable bolts and can be easily disassembled. Therefore, after the two heat exchange covers are disassembled, the two fixing rings, two sets of connecting frames, two sets of baffle frames, two sets of first bidirectional screw rods and two sets of movable gears can be pulled out from the heat exchange shell, and then the damaged heat exchange tube can be disassembled to facilitate the repair or replacement of the damaged heat exchange tube.
[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The heat medium can be poured into the shell side of the heat exchange shell through the liquid inlet pipe, and then the petroleum raw material can be poured into the heat exchange shell through the oil inlet pipe, and then the petroleum raw material will flow into multiple heat exchange tubes, so that the petroleum raw material flows in the tube side of the heat exchange shell, the heat medium will flow out through the liquid outlet pipe, and the petroleum raw material will flow out through the oil outlet pipe. The heat exchange treatment can be carried out through the flow contact between the petroleum raw material and the heat medium in the shell side and the tube side of the heat exchange shell. The two partition plates and two baffles can improve the efficiency of heat exchange between the petroleum raw material and the heat medium, and can generate baffles in the heat exchange shell, and form a certain multi-directional flow in the heat exchange shell, so that the heat medium is evenly distributed on the surface of multiple heat exchange tubes, and the heat transfer of the heat exchange surface is fully utilized, which can force the heat medium to change direction multiple times and increase the flow rate between the tubes. The two fixing rings, two sets of connecting frames and two sets of baffle frames can further improve the efficiency of heat exchange between the petroleum raw material and the heat medium. Bending flow is generated in the multiple heat exchange tubes, and a certain multi-directional flow is formed in the heat exchange tubes, so that the crude oil is evenly distributed on the inner side of the multiple heat exchange tubes, further fully utilizing the heat exchange surface for heat transfer, and also extending the flow path length of the crude oil in the tube. When the heat medium flows in the oil inlet pipe and the liquid outlet pipe, the heat medium will impact on the two hydraulic racks and then drive the synchronous parts, which can drive the two partition plates and the multiple heat exchange tubes to rotate on the heat exchange shell, and can roll and stir the heat medium in the heat exchange shell and the crude oil in the multiple heat exchange tubes. At the same time, the positions of the multiple heat exchange tubes can be adjusted, so that the outer surfaces of the multiple heat exchange tubes can be evenly contacted with the heat medium, the inner surfaces of the multiple heat exchange tubes can be evenly contacted with the crude oil, and the crude oil on the inner side of the multiple heat exchange tubes can be evenly contacted with the heat medium for heat exchange, and thus the crude oil can be evenly heat exchanged. 2. When the synchronous member is driven, the translation member can be driven, and then the two baffles and the multiple detection rings can be driven to move left and right on the multiple heat exchange tubes respectively. The two baffles and the multiple detection rings can be moved left and right to scrape the outer sides of the multiple heat exchange tubes and the inner side of the heat exchange shell, so as to avoid the stains and particles of the heat medium from adhering to the outer sides of the heat exchange tubes and the inner side of the heat exchange shell. At the same time, the two baffles and the multiple detection rings can move left and right on the multiple heat exchange tubes to enhance the baffle effect of the heat medium in the heat exchange shell, further improve the flow state of the heat medium, and enhance the heat medium on the multiple The outer surface of the heat exchange tube has a uniform heat exchange effect. When the synchronous part is driven, the scraping and brushing part can be driven to move left and right on the inner side of the multiple heat exchange tubes respectively. The inner side of the multiple heat exchange tubes can be scraped and brushed by the left and right movement of the two groups of baffles, which can prevent the stains and particles of the petroleum raw materials from adhering to the inner side of the heat exchange tubes. At the same time, the two groups of baffles can move left and right in the multiple heat exchange tubes to enhance the baffle effect of the petroleum raw materials in the heat exchange shell and tube process, further improve the flow state of the petroleum raw materials, and enhance the uniform heat exchange effect of the petroleum raw materials on the inner surface of the multiple heat exchange tubes; 3. When the translation part is driven, it can drive the sensing part, the swinging part and the moving part to move, so as to detect the rupture of multiple heat exchange tubes respectively. When the heat exchange tube is broken, the detection ring moves left and right on the outside of the heat exchange tube, and the petroleum raw material in the heat exchange tube will flow through the crack of the heat exchange tube to the detection cavity in the detection ring to fill it. When the detection cavity is filled with the petroleum raw material, the adjustment block will be squeezed and pushed, so that the annular spring can be compressed, thereby driving the adjustment block to move. When the adjustment block moves, it will contact with the first sensor and be triggered, and then the first sensor will transmit the signal to the alarm to alarm, which can remind the staff that the heat exchange tube is broken and needs to be repaired or replaced. At the same time, according to the triggered first sensor, the staff can know which heat exchange tube is broken, and can remind the staff to stop processing and exchanging the petroleum raw material, so as to avoid leakage and waste of petroleum raw material as much as possible, so as to quickly detect and repair the heat exchange tube, so as to facilitate work. The personnel dismantle and replace the designated broken heat exchange tubes without having to pull out all the heat exchange tubes from the heat exchange shell, which can improve the efficiency of heat exchange tube maintenance. At the same time, the swinging piece can drive the two first marking pens to swing respectively. The two first marking pens can mark the heat exchange tube when they swing, which indicates that there is a rupture on the heat exchange tube, and the location of the rupture is between the two first marking pens, which allows the staff to quickly know the location of the rupture of the heat exchange tube, without the need for the staff to search laboriously, and can quickly find the location of the heat exchange tube that needs to be repaired, thereby improving the speed of heat exchange tube maintenance. In addition, the moving piece can enable the discharge plate to open the connecting pipe, and the petroleum raw materials in the detection chamber can be quickly released through the connecting pipe, so that the adjustment block and the two first marking pens are restored to their initial states, and the two first marking pens are separated from the heat exchange tube, so as to avoid that after the two first marking pens mark the heat exchange tube, when the detection ring drives the two first marking pens to move, the two first marking pens continue to contact and mark the heat exchange tube; 4. The translation part can drive the power part when it is driven. When there is a pit on the inner side of the heat exchange shell, the elastic force of the spiral spring can drive the moving rod and the second marking pen to move in turn. When the moving rod moves to the pit, the second marking pen can mark the side of the pit, so that the staff can quickly know the location of the pit of the heat exchange shell. The staff does not need to search laboriously, and can quickly find the location of the heat exchange shell that needs to be repaired, thereby improving the speed of heat exchange shell repair. At the same time, when the moving rod detects the pit and moves, it will contact with the second sensor and be triggered, and then the second sensor will transmit the signal to the alarm to alarm, which can remind the staff that the heat exchange shell has a pit and needs to be disassembled for repair, so as to avoid the heat exchange shell from being broken due to continuous use; 5. When the heat medium and the petroleum raw material flow in the liquid inlet pipe and the oil inlet pipe respectively, the control components can be driven to make the two control plates open the two discharge pipes respectively, and then the corrosion inhibitor in the corrosion inhibition box will be put into the inner side of the liquid inlet pipe and the oil inlet pipe respectively through the two discharge pipes, so that the corrosion inhibitor will be mixed with the heat medium and the petroleum raw material respectively, so that the corrosion inhibitor is added to the heat medium, which can slow down the corrosion of the heat medium on the inner wall of the heat exchange shell and the outer side of multiple heat exchange tubes, and the corrosion inhibitor is added to the petroleum raw material, which can slow down the corrosion of the petroleum raw material on the inner wall of the heat exchange shell and the inner wall of multiple heat exchange tubes, so as to further enhance the heat exchange effect between the heat medium and the petroleum raw material, and at the same time Through the moving range of the two wedge-shaped adjustment blocks and the pressure strength of the two connecting springs, the feeding amount of the heat medium and the petroleum raw material can be detected, and then the opening size of the two discharge pipes of the two control plates can be adjusted according to the movement of the two wedge-shaped adjustment blocks. The more the pressure feeding amount of the heat medium and the petroleum raw material, the larger the opening of the two discharge pipes, and the more the corrosion inhibitor is released by the two discharge pipes. The smaller the pressure feeding amount of the heat medium and the petroleum raw material, the smaller the opening of the two discharge pipes, and the less the corrosion inhibitor is released by the two discharge pipes. The amount of corrosion inhibitor can be automatically controlled according to the feeding amount of the heat medium and the petroleum raw material to avoid corrosion. Adding too much or too little corrosion inhibitor can ensure the optimization effect of corrosion inhibitor on heat medium and petroleum raw materials, guide the uniform distribution of petroleum raw materials in the pipe process, avoid the formation of laminar flow or uneven flow of petroleum raw materials in the pipe process, improve the heat transfer efficiency of petroleum raw materials, prevent the heat exchange tube from being heated unevenly to produce thermal stress, prevent the heat exchange tube from being deformed, cracked or failed due to thermal stress, and increase the service life of the heat exchanger. There is no need to frequently disassemble and clean the heat exchanger, which can reduce the probability of corrosion of the heat exchanger shell and pipe process. The amount of corrosion inhibitor added can be controlled according to the amount of petroleum raw materials and heat medium to avoid excessive amounts of petroleum raw materials and heat medium. However, if the amount of corrosion inhibitor added is too little, the corrosion inhibition effect of the shell and the tube will be insufficient, and precipitates will still be formed. To avoid too little amount of petroleum raw materials and heat medium, too much corrosion inhibitor will be added, causing unnecessary cost waste. Preventing excessive corrosion inhibitor from having adverse effects on petroleum raw materials and heat medium can reduce the generation of precipitates and try to avoid the heat exchange tubes from being broken and damaged due to pressure. The staff does not need to frequently pull the heat exchange tubes out of the shell for inspection, but can directly detect whether the heat exchange tubes are broken. The inspection method saves time and effort, and the heat medium can evenly exchange heat with the petroleum raw materials on the inside of the heat exchange tubes, thereby improving the efficiency of heat exchange of petroleum raw materials.

[0039] The implementation principle of a high-efficiency heat exchanger for petrochemical industry in the embodiment of the present application is as follows: (1) The heat medium can be poured into the shell side of the heat exchange shell 1 through the liquid inlet pipe 2, and then the petroleum raw material can be poured into the heat exchange shell 1 through the oil inlet pipe 4, and then the petroleum raw material will flow into the plurality of heat exchange tubes 10, so that the petroleum raw material flows in the tube side of the heat exchange shell 1, the heat medium will flow out through the liquid outlet pipe 3, and the petroleum raw material will flow out through the oil outlet pipe 5. Heat exchange treatment can be performed through the flow contact between the petroleum raw material and the heat medium in the shell side and the tube side of the heat exchange shell 1; (2) The two partition plates 9, the two sealing grooves and the two baffles 14 can improve the efficiency of heat exchange between the petroleum raw material and the heat medium, generate baffles in the heat exchange shell 1, and form a certain multi-directional flow in the heat exchange shell 1, so that the heat medium is evenly distributed on the surface of the plurality of heat exchange tubes 10, and the heat exchange surface is fully utilized for heat transfer, which can force the heat medium to change direction multiple times, improve the convective heat transfer coefficient of the heat medium shell side, and improve the flow state of the heat medium, reduce the influence of vortex and backflow in the shell side, thereby reducing the degree of pressure drop, and can also extend the flow channel length of the heat medium in the shell side, increase the flow velocity between the tubes, thereby maintaining a high heat transfer effect while reducing the pressure drop caused by the excessively high flow velocity of the heat medium; (3) The two fixing rings 36, the two sets of connecting frames 37 and the two sets of baffle frames 38 can further improve the efficiency of heat exchange between the crude oil and the heat medium, generate baffles in the multiple heat exchange tubes 10, and form a certain multi-directional flow in the heat exchange tubes 10, so that the crude oil is evenly distributed on the inner side of the multiple heat exchange tubes 10, further fully utilizing the heat exchange surface for heat transfer, forcing the crude oil to change direction multiple times, improving the convective heat transfer coefficient of the crude oil tube pass, and improving the flow state of the crude oil, reducing the influence of vortex and backflow in the tube pass, thereby reducing the degree of pressure drop, and extending the flow path length of the crude oil in the tube pass, thereby reducing the pressure drop caused by the excessively high flow rate of the crude oil while maintaining a high heat transfer effect; (4) When the heat medium flows in the oil inlet pipe 4 and the liquid outlet pipe 3, the heat medium will impact on the two hydraulic racks 6, thereby driving the two hydraulic racks 6 to rotate clockwise, which can respectively drive the two transmission gears 7, the two power gears 8, the two partition plates 9, the multiple heat exchange tubes 10, the multiple detection rings 15, the two baffles 14, the two fixing rings 36, the two sets of connecting racks 37 and the two sets of baffle racks 38 to rotate on the heat exchange shell 1, so as to tumble and stir the heat medium in the heat exchange shell 1 and the oil raw materials in the multiple heat exchange tubes 10, thereby enhancing the tumbling effect of the heat medium inside the heat exchange shell 1. The position of the plurality of heat exchange tubes 10 can be adjusted at the same time, so that the outer surfaces of the plurality of heat exchange tubes 10 can be evenly contacted with the heat medium, the inner surfaces of the plurality of heat exchange tubes 10 can be evenly contacted with the petroleum raw materials, the petroleum raw materials inside the plurality of heat exchange tubes 10 can be evenly contacted with the heat medium for heat exchange, and the petroleum raw materials can be evenly heat exchanged. At the same time, when the plurality of heat exchange tubes 10 rotate, the pressure of the heat medium on the plurality of heat exchange tubes 10 is reduced, the probability of damage to the heat exchange tubes 10 is reduced, and the plurality of heat exchange tubes 10 can be evenly contacted with the heat medium for stamping; (5) When the two partition plates 9 rotate, they will also drive the two second bidirectional screws 12 and the two sets of connecting gears 13 to rotate in a circle. When the two sets of connecting gears 13 rotate in a circle, they can respectively drive the two sets of connecting gears 13 and the two second bidirectional screws 12 to rotate by themselves through meshing with the two internal gears 49. Then, while the two second bidirectional screws 12 rotate by themselves, they can respectively drive the two baffles 14 and the multiple detection rings 15 to move left and right on the multiple heat exchange tubes 10. By moving the two baffles 14 and the multiple detection rings 15 left and right, the outer sides of the multiple heat exchange tubes 10 and the inner side of the heat exchange shell 1 are scraped and brushed, which can prevent the stains and particles of the heat medium from adhering to the outer sides of the heat exchange tubes 10 and the inner side of the heat exchange shell 1. At the same time, when the two baffles 14 and the multiple detection rings 15 move left and right on the multiple heat exchange tubes 10, the baffle effect of the heat medium in the shell of the heat exchange shell 1 can be enhanced, which can further improve the flow state of the heat medium and enhance the uniform heat exchange effect of the heat medium on the outer surfaces of the multiple heat exchange tubes 10. (6) When the two partition plates 9 rotate, they also drive the two sets of rolling bearings 50, the two sets of support rods 51, the two sets of first bidirectional screws 34 and the two sets of movable gears 35 to rotate in a circular manner. When the two sets of movable gears 35 rotate in a circular manner, they can respectively drive the two sets of movable gears 35 and the two sets of first bidirectional screws 34 to rotate by meshing with the two internal gears 49. Then, when the two sets of first bidirectional screws 34 rotate by themselves, they can respectively drive the two fixing rings 36, the two sets of connecting frames 37 and the two sets of baffles. The racks 38 move left and right on the inner sides of the plurality of heat exchange tubes 10 respectively. The inner sides of the plurality of heat exchange tubes 10 are scraped and brushed by the left and right movement of the two sets of baffle racks 38, so as to prevent the stains and particles of the petroleum raw materials from adhering to the inner sides of the heat exchange tubes 10. Meanwhile, the two sets of baffle racks 38 move left and right in the plurality of heat exchange tubes 10, so as to enhance the baffle effect of the petroleum raw materials in the heat exchange shell 1, further improve the flow state of the petroleum raw materials, and enhance the uniform heat exchange effect of the petroleum raw materials on the inner surfaces of the plurality of heat exchange tubes 10; (7) At the same time, the multiple detection rings 15 move left and right on the multiple heat exchange tubes 10 respectively, and the multiple heat exchange tubes 10 can be detected for rupture. When the heat exchange tube 10 is ruptured, the detection ring 15 moves left and right on the outside of the heat exchange tube 10, and the oil raw material in the heat exchange tube 10 will flow into the detection cavity in the detection ring 15 through the crack of the heat exchange tube 10, and then the detection cavity can be filled. When the oil raw material fills the detection cavity, it squeezes and pushes the adjustment block 16, and then the annular spring 17 is in a compressed state, thereby driving the adjustment block 16 to move. When the adjustment block 16 moves, it will contact the first sensor 18 The first sensor 18 is triggered by contact, and then the first sensor 18 transmits a signal to the alarm 47 to alarm, which can remind the staff that the heat exchange tube 10 is broken and needs to be repaired or replaced. At the same time, according to the triggered first sensor 18, the staff can know which heat exchange tube 10 is broken, and can remind the staff to stop processing and exchanging heat for the petroleum raw materials, and try to avoid leakage and waste of petroleum raw materials, so as to quickly detect and repair the heat exchange tube 10, so that the staff can disassemble and replace the specified broken heat exchange tube 10, without having to extract all the heat exchange tubes 10 from the heat exchange shell 1, which can improve the efficiency of heat exchange tube 10 repair; (8) At the same time, because the two adjustment frames 19 are hinged to the detection ring 15, the adjustment block 16 will push the two adjustment frames 19 to swing when it moves, so that the two injection springs 20 are stretched. Therefore, when the two adjustment frames 19 swing, they can respectively drive the two first marking pens 21 to swing. When the two first marking pens 21 swing, they can mark the heat exchange tube 10, which means that there is a rupture on the heat exchange tube 10, and the position of the rupture is between the two first marking pens 21. Therefore, the staff can quickly know the position of the rupture of the heat exchange tube 10, without the staff having to search laboriously, and can quickly find the position of the heat exchange tube 10 that needs to be repaired, thereby improving the speed of repairing the heat exchange tube 10; (9) When the adjusting block 16 moves, it pushes the second wedge block 22 to move, so that the first spring 23 is squeezed and the third wedge block 24 is pushed to move. When the third wedge block 24 moves, the elastic force of the second spring 27 can adjust the position of the connecting rod 26 and the third wedge block 24 to fit in contact with each other, and then the connecting rod 26 and the discharge plate 25 can be driven to move in turn, so that the discharge plate 25 opens the connecting pipe 28, and then the elastic force of the annular spring 17 can quickly release the petroleum raw materials in the detection chamber through the connecting pipe 28, so that the adjusting block 16 returns to its initial state, and then the elastic force of the two injection springs 20 , the two adjustment racks 19 and the two first marking pens 21 will also return to their initial state, so that the two first marking pens 21 are separated from the heat exchange tube 10, so as to avoid that after the two first marking pens 21 mark the heat exchange tube 10, when the detection ring 15 drives the two first marking pens 21 to move, the two first marking pens 21 continue to contact and mark the heat exchange tube 10, so as to avoid that the two first marking pens 21 mark the unbroken parts of the heat exchange tube 10, so that the two first marking pens 21 can quickly return to their original state after marking the broken parts of the heat exchange tube 10, so that the detection ring 15 and the two first marking pens 21 can continue to detect and mark the heat exchange tube 10; (10) When the two baffles 14 move, they will also drive the two moving rods 30, the two connecting blocks 52 and the two second marking pens 33 to move, so that the two moving rods 30 can detect the inner wall of the heat exchange shell 1 when they move. When there is a pit on the inner side of the heat exchange shell 1, the elastic force of the spiral spring 31 can drive the moving rod 30 and the second marking pen 33 to move in sequence. When the moving rod 30 moves to the pit, the second marking pen 33 can mark the side of the pit, so that the staff can quickly know the location of the pit in the heat exchange shell 1. The staff does not need to search laboriously, and can quickly find the location of the heat exchange shell 1 that needs to be repaired, thereby improving the speed of repairing the heat exchange shell 1. At the same time, when the moving rod 30 detects the pit and moves, it will contact the second sensing pen 33. The second sensor 32 is triggered by contact with the heat exchange shell 1, and then the second sensor 32 transmits a signal to the alarm 47 to alarm, which can remind the staff that there is a pit in the heat exchange shell 1 and needs to be disassembled and repaired to avoid the heat exchange shell 1 from being broken due to continuous use. At the same time, when the baffle 14 moves, the moving rod 30 will also be moved out of the pit, so that the second marking pen 33 is separated from the heat exchange shell 1 to avoid the second marking pen 33 marking the heat exchange shell 1. After that, when the baffle 14 drives the second marking pen 33 to move, the second marking pen 33 continues to contact and mark the heat exchange shell 1, so that the coil spring 31 returns to the compressed state, and the moving rod 30 and the second marking pen 33 return to the initial state, so that the second sensor 32 and the second marking pen 33 continue to detect and mark the heat exchange shell 1; (11) When it is necessary to dismantle and repair the designated heat exchange tube 10, the two heat exchange covers 53 on the heat exchange shell 1 are first dismantled. Since the first bidirectional screw 34 is connected to the support rod 51 by a movable bolt, the first bidirectional screw 34 and the support rod 51 can be easily dismantled. Therefore, after the two heat exchange covers 53 are dismantled, the two fixing rings 36, the two sets of connecting frames 37, the two sets of baffle frames 38, the two sets of first bidirectional screws 34 and the two sets of movable gears 35 can be pulled out from the heat exchange shell 1, and then the damaged heat exchange tube 10 can be dismantled to facilitate the repair or replacement of the damaged heat exchange tube 10. By respectively providing a plurality of first convex holes and a plurality of second convex holes on the two partition plates 9, the sealing between the plurality of heat exchange tubes 10 and the two partition plates 9 can be ensured to prevent the petroleum raw materials from mixing with the heat medium. (12) When the heat medium and the oil raw material flow in the liquid inlet pipe 2 and the oil inlet pipe 4 respectively, the pressure of the heat medium and the oil raw material in the liquid inlet pipe 2 and the oil inlet pipe 4 can be detected by the two wedge-shaped adjustment blocks 41. When the heat medium and the oil raw material flush the two wedge-shaped adjustment blocks 41 respectively, the two connecting springs 43 are compressed and then the two first wedge blocks 42 are driven to move respectively. When the two first wedge blocks 42 move, the elastic force of the two telescopic springs 46 can adjust the two movable rods 4 5 are respectively in contact with the two first wedge-shaped blocks 42, and then the two movable rods 45 and the two control plates 44 can be respectively driven to move, so that the two control plates 44 can respectively open the two discharge pipes 40, and then the corrosion inhibitor in the corrosion inhibition box 39 will be respectively put into the inner side of the liquid inlet pipe 2 and the oil inlet pipe 4 through the two discharge pipes 40, so that the corrosion inhibitor will be mixed with the heat medium and the petroleum raw material respectively, so that the corrosion inhibitor is added to the heat medium, which can reduce the heat medium The impact on the inner wall of the heat exchange shell 1 and multiple heat exchangers The corrosion of the outer side of the tube 10 is prevented by adding the corrosion inhibitor into the petroleum raw material, which can slow down the corrosion of the inner wall of the heat exchange shell 1 and the inner walls of multiple heat exchange tubes 10 by the petroleum raw material, so as to further enhance the heat exchange effect between the heat medium and the petroleum raw material. At the same time, the moving range of the two wedge-shaped adjustment blocks 41 and the pressure of the two connecting springs 43 can be used to detect the feeding amount of the heat medium and the petroleum raw material, and then the opening size of the two control plates 44 to the two discharge pipes 40 can be adjusted according to the movement of the two wedge-shaped adjustment blocks 41. The more the pressure feeding amount of the heat medium and the petroleum raw material, the larger the opening of the two discharge pipes 40, and the more the corrosion inhibitor is released by the two discharge pipes 40. The smaller the pressure feeding amount of the heat medium and the petroleum raw material, the smaller the opening of the two discharge pipes 40, and the less the corrosion inhibitor is released by the two discharge pipes 40. The amount of corrosion inhibitor can be automatically controlled according to the feeding amount of the heat medium and the petroleum raw material to avoid excessive or insufficient addition of corrosion inhibitor, so as to ensure the optimization effect of the corrosion inhibitor on the heat medium and the petroleum raw material.
[0040] Compared with the prior art, the overall structure is simple and easy to use, and can guide the uniform distribution of the petroleum raw materials in the pipe process, avoid the phenomenon of laminar flow or uneven flow of the petroleum raw materials in the pipe process, prevent the heat exchange tube 10 from failing to fully exert its heat transfer capacity, ensure the contact area between the petroleum raw materials and the inner wall of the heat exchange tube 10, facilitate the effective transfer of heat in the pipe process, improve the heat transfer efficiency of the petroleum raw materials, prevent the heat exchange tube 10 from being heated unevenly to generate thermal stress, prevent the heat exchange tube 10 from being deformed, cracked or failed due to thermal stress, and increase the service life of the heat exchanger. There is no need to frequently disassemble and clean the heat exchanger, which can reduce the probability of corrosion of the heat exchanger shell and the pipe process, and can control the amount of corrosion inhibitor added according to the amount of petroleum raw materials and heat medium to avoid the petroleum raw materials and heat medium. Too much amount and too little corrosion inhibitor will result in insufficient corrosion inhibition effect on the shell and tube side, and precipitates will still form. Avoid too little amount of petroleum raw materials and heat medium and too much corrosion inhibitor, which will cause unnecessary cost waste. Prevent excessive corrosion inhibitor from having adverse effects on petroleum raw materials and heat medium, reduce the generation of precipitates, and try to avoid the heat exchange tube 10 from being broken and damaged due to pressure. The staff does not need to frequently pull the heat exchange tube 10 out of the shell side for inspection, and can directly detect whether the heat exchange tube 10 is broken. The detection method saves time and effort and improves the use efficiency of the heat exchanger. The heat medium can evenly exchange heat with the petroleum raw material on the inside of the heat exchange tube 10, improve the efficiency of heat exchange of petroleum raw materials, and ensure the performance and effect of the heat exchanger.
[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
