Description

Technical Field

[0001] The invention relates to the technical field of steam heat exchangers, and in particular to a heat exchanger device for a steam system. Background Art

[0002] A steam system is a heat transfer and utilization system that uses water vapor (steam) as the working medium. Heat exchangers are often used in steam systems, which enable heat exchange between two fluids (liquids or gases) at different temperatures without mixing.

[0003] The solid thermal storage steam unit is an efficient energy utilization device that combines solid thermal storage technology and steam generation technology. It can store electricity during periods of low electricity prices (such as the night off-peak period) and then release the stored heat to generate steam during peak electricity consumption periods. The steam system and the solid thermal storage steam unit complement each other in function and jointly achieve efficient and reliable steam production and supply.

[0004] At present, most of the steam heat exchangers used in solid thermal storage steam units are shell and tube steam heat exchangers. For example, the patent with announcement number CN212058370U discloses a steam heat exchanger. By setting a first partition, a first baffle and a second baffle, the movement time of water in the heat exchange tube is prolonged, thereby prolonging the heat exchange time between water and high-temperature steam, so that the heat exchange between water and high-temperature steam is sufficient; in the steam heat exchanger, the first baffle and the second baffle are both inclined, and the first baffle and the second baffle are both made of copper material, so that the heat of the high-temperature steam is quickly transferred to the first baffle, and then to the water in the heat exchange tube, which can further improve the heat exchange efficiency between the high-temperature steam and the water; the steam heat exchanger also includes a first baffle and a second baffle, and the steam moves in an S-shaped curve between the first baffle and the second baffle, thereby fully prolonging the heat exchange time between the steam and the water in the heat exchange tube and improving the heat exchange efficiency.

[0005] However, the above steam heat exchanger still has the following problems in actual use:

[0006] One end of the steam heat exchanger is a pipe box, where a fluid (such as water or oil) flows through the inlet here, passes through several pipes located inside the shell, exchanges heat with another fluid (steam), returns to the pipe box again, and is discharged from the outlet.

[0007] Because the condensate after steam condensation is usually purer and not easy to scale in the shell side, the cleaning frequency of the shell side is low. However, because water or other fluids often flow in the tube side, it is easy for dirt to remain on the inner wall of the pipe, so the inside of the pipe needs to be cleaned frequently.

[0008] The existing pipeline cleaning method is mostly to introduce cleaning liquid through the inlet, and then discharge it from the outlet after the cleaning liquid flows through the pipeline (the same process as during heat exchange). This method seems to be able to flush all pipes at one time, which seems to be very efficient. However, the dirt distribution in different pipes may be uneven, and some pipes may have stubborn dirt or sediment. In addition, during a one-time flushing, the pollutants may spread from one pipe to another under the action of water flow, causing secondary pollution. Summary of the invention

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] See also Figure 1-Figure 8 A heat exchanger device for a steam system comprises a shell 1, a mounting plate 14 installed inside the shell 1, a plurality of pipes 13 installed on the mounting plate 14, a pipe box 2 installed on one side of the shell 1, and a partition 15 installed in the pipe box 2. The outer wall of the pipe box 2 away from the shell 1 is fixedly connected with a protection box 3, and the side of the protection box 3 away from the pipe box 2 is provided with an operating chamber 12. The upper end of the inner wall of the operating chamber 12 is fixedly connected with a support plate 16, one end of the support plate 16 is connected with a moving mechanism, the output end of the moving mechanism is connected with a rotating mechanism, the output end of the rotating mechanism is connected with a transmission assembly, and the inner walls of the other two ends of the transmission assembly are connected with a connecting assembly Parts, one end of the two connecting components passes through the protection box 3 to the inside of the pipe box 2, the other ends of the two connecting components pass through the protection box 3 to the outside of the protection box 3 and are respectively connected with diversion components, the two connecting components located inside the pipe box 2 are respectively located on both sides of the partition 15, and are symmetrically arranged, the two connecting components located inside the pipe box 2 are connected with protection components and alignment components, one end of the two alignment components close to the connecting components is respectively located in the two protection components, the other ends of the two alignment components are matched and aligned with the mounting plate 14, and the two alignment components are respectively matched and aligned with the two ends of the pipeline 13, and a monitoring mechanism is also connected to the inside of one of the connecting components.

[0037] The heat exchanger device for a steam system in the present invention is similar in structure to the existing heat exchanger device for a steam system, such as a steam heat exchanger disclosed in patent publication number CN212058370U. Figures 1 to 8 As shown, the heat exchanger device for a steam system in the present invention can be used in the following steps:

[0038] First, the two inlets and outlets of the shell 1 and the two inlets and outlets on the pipe box 2 are respectively connected and sealed with the external pipelines, and then used normally through the heat exchanger device in conjunction with solid heat storage. After use, some impurities will inevitably remain inside the pipe 13, and the inside of the pipe 13 needs to be cleaned at this time.

[0039] Before cleaning the inside of the pipe 13 , the inside of the pipe box 2 may be flushed through the two inlets and outlets on the pipe box 2 to ensure that the inside of the pipe box 2 does not need to be cleaned later.

[0040] The rotating mechanism is then turned on by an external controller. After the rotating mechanism is started, the protection component and the alignment component inside the pipe box 2 are controlled to rotate to one side at a certain angle, so that the end of the alignment component is aligned with the opening of one of the pipes 13 on the mounting plate 14.

[0041] Then the moving mechanism is started again through the external controller. After the moving mechanism is started, it will push the rotating mechanism, transmission component, connecting component, etc. forward together. While the connecting component is moving, the diversion component, protection component and alignment component connected at both ends will move in the same direction together.

[0042] When the protection component and the alignment component move, they will slowly move toward the mounting plate 14 , and because the rotating mechanism has adjusted the angle before, when the moving mechanism moves to a certain position, it will just touch the opening of the first pipe 13 on the mounting plate 14 , and the interior of the alignment component will just be connected to the interior of this pipe 13 .

[0043] Similarly, due to the function of the transmission assembly, when the rotating mechanism initially adjusts the angle of the alignment assembly, it will also adjust the angles of the two alignment assemblies at the same time, so that the two alignment assemblies will be exactly connected to the two ends of the pipe 13.

[0044] Connect an external high-pressure pump to one end of one of the diversion components through a water pipe, and connect one end of the other diversion component to the external sewage pipe. After all the connections are completed, start the high-pressure pump through the external controller.

[0045] After the high-pressure pump is started, it will pump cleaning fluid into the diversion component connected to it, and then the cleaning fluid will enter the alignment component through the connecting component, and then enter the previously aligned pipe 13 through the alignment component, thereby flushing impurities on the inner wall of the pipe 13.

[0046] The cleaned sewage will be discharged into the external sewage pipe from another aligned component, connecting component and diversion component that are matched and aligned at the other end of the pipeline 13, and then this part of the sewage can be subsequently treated.

[0047] When the interior of the first pipe 13 is cleaned, turn off the external high-pressure pump, then start the moving mechanism again, retract the rotating mechanism, transmission components, etc. for a certain distance to reduce the friction between the alignment component and the mounting plate 14, then start the rotating mechanism again, align the alignment component with the second pipe 13 for cleaning.

[0048] When one circle on the mounting plate 14 has been cleaned (for example, cleaned from the inside out), after the moving mechanism pulls the rotating mechanism, transmission assembly, etc. back a certain distance, the protective assembly can push the alignment assembly outward for a certain distance, so that the alignment assembly can match and align with the outer circle of pipes 13, and then continue to repeat the above cleaning steps until all pipes 13 are cleaned.

[0049] After all the cleaning is completed, turn off the external high-pressure pump, then connect the output end of the external air compressor to the end of one of the diversion components away from the external high-pressure pump, and then start the external air compressor to introduce compressed air into the pipe 13 to accelerate the drying of the inside of the pipe 13.

[0050] After all drying, the moving mechanism is started to move the rotating mechanism, the transmission assembly, and the alignment assembly to a side of the pipe box 2 away from the mounting plate 14 to avoid obstruction of normal use of subsequent heat exchanger devices.

[0051] Special mention should be made here:

[0052] The shell 1, the mounting plate 14, the plurality of pipes 13, the pipe box 2 and the partition 15 are all existing structures inside the existing shell and tube steam heat exchanger. The connection relationship and operation principle between the various components are mature technologies, so they will not be described in detail this time.

[0053] The external high-pressure pump, external air compressor, external sewage pipe, and external controller mentioned above are all existing technologies, so their principles are not described in detail here. Because the positions of the several pipes 13 on the mounting plate 14 are fixed, the degree of each rotation angle (for example, 45°, 90°, etc. are not limited) can be programmed in advance on the external controller (such as a PLC controller). That is, after the rotating mechanism is started, each rotation will be exactly aligned with the next pipe 13. Similarly, each movement of the moving mechanism can also move the alignment component to a position aligned with the next pipe 13 each time.

[0054] Because the blockage degree inside different pipes 13 is different, when flushing the inside of the pipe 13, the cleaning condition inside the pipe 13 can be monitored in real time by a monitoring mechanism until the cleaning standard is reached and the flushing stops.

[0055] As a preferred solution of the present invention, the moving mechanism includes a moving motor 17, a screw rod 18 and a slider 39. A slide groove 38 is penetrated through the upper surface of the support plate 16. The outer wall of the moving motor 17 is fixedly connected to the end of the support plate 16 away from the pipe box 2. The output shaft of the moving motor 17 is fixedly connected to one end of the screw rod 18. The other end of the screw rod 18 penetrates the support plate 16, the slider 39 and the slide groove 38. The outer wall of the screw rod 18 is rotatably connected to the inner wall of the support plate 16. The outer wall of the screw rod 18 is threadedly connected to the inner wall of the slider 39. The outer wall of the slider 39 is slidably connected to the inner wall of the slide groove 38. The lower end of the slider 39 penetrates the slide groove 38 and is connected to the rotating mechanism.

[0056] More specifically, when it is necessary to control the movement of the rotating mechanism, it is only necessary to turn on the switch of the moving motor 17 through an external controller. After the moving motor 17 is started, the output end can control the rotation of the screw rod 18. After the screw rod 18 rotates, it can move the slider 39 in the slide groove 38. When the slider 39 moves, it will also move the rotating mechanism connected to it, thereby controlling its position to change.

[0057] As a preferred solution of the present invention, the rotating mechanism includes a moving plate 19, a rotating motor 20 and a transmission rod 41. The outer wall of the rotating motor 20 is fixedly connected to the lower end of the slider 39, the output shaft of the rotating motor 20 is fixedly connected to one end of the transmission rod 41, and the other end of the transmission rod 41 simultaneously penetrates the upper end of the transmission assembly and the upper end of the moving plate 19, and is rotatably connected to the inner wall of the moving plate 19 at the penetration point, and the upper surface of the moving plate 19 is slidably connected to the bottom surface of the support plate 16.

[0058] More specifically, when it is necessary to control the transmission component to rotate, it is only necessary to start the rotating motor 20 through an external controller. After the rotating motor 20 is started, the output shaft can rotate with the transmission rod 41. After the transmission rod 41 rotates, it can rotate with the transmission component.

[0059] Similarly, when the moving motor 17 is started, the slider 39 can move with the rotating motor 20 , and then can pull the moving plate 19 to move together through the transmission rod 41 .

[0060] As a preferred solution of the present invention, the transmission component includes a No. 1 gear 31, a No. 2 gear 32 and a No. 3 gear 33. The No. 1 gear 31 is sleeved and fixedly connected to the outer wall of the transmission rod 41, and the No. 2 gear 32 and the No. 3 gear 33 are respectively sleeved on the outside of the two connecting components. The No. 1 gear 31 is meshed with the No. 2 gear 32, and the No. 2 gear 32 is also meshed with the No. 3 gear 33. The sides of the No. 1 gear 31, the No. 2 gear 32 and the No. 3 gear 33 away from the rotating motor 20 are all against the surface of the movable plate 19.

[0061] More specifically, when the rotating motor 20 is started, the transmission rod 41 can rotate with the number one gear 31, and then the number one gear 31 can mesh with the number two gear 32 to rotate, and then the number two gear 32 will mesh with the number three gear 33 to rotate, so that the two connected components can be rotated together through the number two gear 32 and the number three gear 33, and because the rotation directions of the number two gear 32 and the number three gear 33 are opposite, the rotation directions of the two connected components are also opposite.

[0062] As a preferred embodiment of the present invention, the two connecting components include an outer tube 21, an inner tube 22, a fixed ring 34, a sealed bearing 35 and a docking tube 40. One end of the two fixed rings 34 is fixedly connected to the side of the second gear 32 and the third gear 33 away from the movable plate 19, respectively. The outer ring of the sealed bearing 35 is fixedly connected to the inner wall of the fixed ring 34, and the inner ring of the sealed bearing 35 is fixedly connected to the outer wall of the outer tube 21. One side of the docking tube 40 is abutted against one end of the outer tube 21 located in the sealed bearing 35, and the other side of the docking tube 40 is fixedly connected to one end of the inner tube 22. The other end of the inner tube 22 passes through the outer walls of the movable plate 19, the protective box 3 and the tube box 2 to the interior of the tube box 2, and is connected to the protective component and the alignment component. The outer walls of the two inner tubes 22 are also fixedly connected to the inner walls of the second gear 32 and the third gear 33, respectively. The end of the outer tube 21 away from the docking tube 40 passes through the inner wall of the protective box 3 to the outside of the protective box 3, and is connected to the diversion component.

[0063] More specifically, when the second gear 32 and the third gear 33 rotate, they will cause the fixing ring 34 and the inner tube 22 to rotate together. Since the fixing ring 34 and the outer tube 21 are rotatably connected via the sealing bearing 35, when the second gear 32 rotates, the outer tube 21 will not rotate together (because the other end of the outer tube 21 is restricted by the diverter component), and the butt joint 40 will rotate with the inner tube 22. However, since the butt joint 40 and the outer tube 21 are both located in the sealing bearing 35, the cleaning liquid will not leak. When the inner tube 22 rotates, it will also cause the protective component and the alignment component located inside the tube box 2 to rotate, so the above-mentioned purpose of cleaning the inside of the pipeline 13 can be achieved.

[0064] As a preferred solution of the present invention, the protective component includes a waterproof box 23, a connecting block 24 and an electric push rod 30. A storage cavity 42 is opened inside the waterproof box 23. The end of the inner tube 22 away from the docking tube 40 passes through the side wall of the waterproof box 23, and the outer wall of the inner tube 22 is fixedly connected to the inner wall of the waterproof box 23 at the penetration point, and the end of the inner tube 22 located in the waterproof box 23 is connected to the alignment component, the outer wall of the electric push rod 30 is fixedly connected to the bottom surface of the storage cavity 42, the output end of the electric push rod 30 passes through the inner wall of the waterproof box 23 to the outside of the waterproof box 23, and is fixedly connected to one end of the connecting block 24, and the other end of the connecting block 24 is connected to the alignment component.

[0065] More specifically, when the inner tube 22 rotates, the waterproof box 23 connected to the inner tube 22 will rotate together, and then the electric push rod 30 located in the internal storage cavity 42 of the waterproof box 23 and the connecting block 24 connected to the electric push rod 30 will rotate together, thereby achieving the purpose of adjusting the angle of the alignment component to align with the pipe 13.

[0066] In addition, when the height of the alignment assembly needs to be changed, it is only necessary to turn on the switch of the electric push rod 30. After the electric push rod 30 is started, the output end extends outward or retracts to pull the connecting block 24 to move together, and then move the alignment assembly together through the connecting block 24.

[0067] It should be noted here that: in actual application, the number of the same circle of the pipe 13 in the shell 1 may be greater, and the number of circles may also be greater. In this case, the electric push rod 30 can be set as a multi-stage electric push rod 30, thereby reducing the internal space occupied by the electric push rod 30 in the pipe box 2.

[0068] As a preferred embodiment of the present invention, the alignment assembly includes an L-shaped tube 25, a trumpet tube 26, a sealing ring 27, a waterproof solenoid valve 29 and a flexible hose 43, one end of the flexible hose 43 is fixedly connected to one end of the inner tube 22 located in the storage chamber 42, the other end of the flexible hose 43 is fixedly connected to one end of the L-shaped tube 25, the other end of the L-shaped tube 25 passes through the waterproof box 23 and the connecting block 24, and is fixedly connected to the narrower end of the trumpet tube 26, the wider end of the trumpet tube 26 is fixedly connected to one end of the sealing ring 27, the other end of the sealing ring 27 is abutted against the surface of the mounting plate 14, the outer wall of the L-shaped tube 25 is slidably connected to the inner wall of the waterproof box 23 at the penetration point, the outer wall of the L-shaped tube 25 is fixedly connected to the penetration point of the connecting block 24, and the waterproof solenoid valve 29 is arranged inside the end of the L-shaped tube 25 close to the trumpet tube 26.

[0069] More specifically, when the waterproof box 23 moves along with the inner tube 22, the connecting block 24 will pull the L-shaped tube 25 to move together, and then the L-shaped tube 25 can pull the horn tube 26, the sealing ring 27 and the waterproof solenoid valve 29 to move together, thereby reducing the wear between the sealing ring 27 and the mounting plate 14.

[0070] In addition, when cleaning liquid or compressed air is injected into the diverter assembly, the cleaning liquid will enter the butt joint pipe 40 and the inner pipe 22 through the outer pipe 21, then enter the flexible hose 43 through the inner pipe 22, then enter the L-shaped pipe 25, the bell pipe 26 and the sealing ring 27 through the flexible hose 43, and finally enter the pipe 13 along the sealing ring 27, thereby flushing the inside of the pipe 13. Similarly, the flushed sewage will enter another sealing ring 27 from the other end of the pipe 13, then follow the bell pipe 26, the L-shaped pipe 25, the flexible hose 43, the inner pipe 22, the butt joint pipe 40 and the outer pipe 21, and finally be discharged from another diverter assembly to the external sewage pipe.

[0071] Special mention should be made here:

[0072] The flexible hose 43 is provided in consideration of the fact that the L-shaped tube 25 , the trumpet tube 26 , etc. may change position following the electric push rod 30 . Therefore, the flexible hose 43 is provided to be deformable so as not to affect the overall connectivity and not to occupy the space in the storage cavity 42 .

[0073] By setting up a waterproof solenoid valve 29, the inside of the bell tube 26 can be sealed during the non-cleaning period, so as to prevent the normal heat exchange medium from entering the bell tube 26, L-shaped tube 25, flexible hose 43, inner tube 22, docking tube 40 and outer tube 21, causing waste of resources.

[0074] As a preferred solution of the present invention, the diversion component includes a three-way pipe 6, an inlet and outlet liquid pipe 7, an inlet and outlet air pipe 8 and two manual valves 9. One end of the three-way pipe 6 is fixedly connected to an end of the outer pipe 21 away from the docking pipe 40, and the other two ends of the three-way pipe 6 are respectively fixedly connected to one end of the inlet and outlet liquid pipe 7 and the inlet and outlet air pipe 8. The two manual valves 9 are respectively arranged inside the inlet and outlet liquid pipe 7 and the inlet and outlet air pipe 8.

[0075] More specifically, when cleaning is required, first ensure that the two manual valves 9 are closed, then connect the inlet and outlet liquid pipes 7 to the external high-pressure pump, and then connect the inlet and outlet air pipes 8 to the external air compressor, and then open the manual valves 9 on the inlet and outlet liquid pipes 7 and the inlet and outlet air pipes 8 respectively according to the cleaning steps.

[0076] As a preferred solution of the present invention, the monitoring mechanism includes a turbidity sensor 36 and a flow sensor 37. The turbidity sensor 36 and the flow sensor 37 are both embedded in and fixedly connected to the inner wall of the same outer tube 21, and the monitoring ends of the turbidity sensor 36 and the flow sensor 37 are both located inside the outer tube 21.

[0077] More specifically, during cleaning, the turbidity of the cleaning liquid circulating inside the outer tube 21 can be monitored in real time by the turbidity sensor 36, so that it can be determined more quickly whether the cleaning is complete.

[0078] Similarly, by setting up a flow sensor 37, the internal flow of the outer tube 21 can be monitored in real time to determine the blockage situation inside the pipeline 13. For example, if the difference between the outflow flow and the injection flow exceeds the range value, it means that the blockage is serious. At this time, you can consider increasing the injection volume for flushing, or directly open the pipe box 2 for maintenance.

[0079] As a preferred solution of the present invention, a plurality of installation openings 28 connected to the operating chamber 12 are provided on the side of the protective box 3 away from the pipe box 2, and the inner wall at the opening of the operating chamber 12 is slidably connected to the disassembly plate 4, and the side wall of the disassembly plate 4 is fixedly connected to a plurality of installation blocks 5, and the outer walls of the plurality of installation blocks 5 are respectively located in the installation openings 28 and are all fastened together by bolts, a heat dissipation port 11 is penetrated through the upper end of the disassembly plate 4, and a dustproof net 10 is fixedly connected to the inner wall of the heat dissipation port 11, the outer walls of the two outer tubes 21 both penetrate the lower end of the disassembly plate 4, and the outer walls of the outer tubes 21 are slidably connected to the inner wall of the disassembly plate 4, and the two diversion components are both located on the side of the disassembly plate 4 away from the protective box 3.

[0080] More specifically, by providing the disassembly plate 4 , it is possible to prevent external debris from falling into the operating cavity 12 from the opening of the operating cavity 12 , causing the first gear 31 , the second gear 32 , the third gear 33 and other components inside the operating cavity 12 to become stuck.

[0081] By providing the heat dissipation port 11 and the dustproof net 10 , the normal heat dissipation of the moving motor 17 and the rotating motor 20 can be maintained, and the dustproof effect can be continued to be achieved.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
