Description

Technical Field

[0001] This invention relates to the field of steam compressor technology, specifically to an MVR centrifugal steam compressor. Background Technology

[0002] MVR evaporation systems are a new type of evaporation system used to replace conventional single-effect or multi-effect evaporation systems. Because they can significantly increase the saturation pressure and saturation temperature of the secondary steam by mechanically pressurizing it with relatively low electrical energy consumption, the amount of primary steam (also called live steam or power steam) used can be reduced or completely replaced. Thus, a large amount of the latent heat of vaporization in the secondary steam can be recovered with relatively low electrical energy consumption, significantly reducing energy consumption in the evaporation or concentration process and achieving significant energy-saving benefits.

[0003] In the prior art, Chinese patent publication number "CN212055169U" discloses a centrifugal steam compressor with a heat insulation mechanism. It is connected to a speed-reducing pipe through a mesh tube, and the mesh tube is equipped with heat dissipation fins to allow the high-temperature gas to dissipate heat more quickly. The speed-reducing pipe is connected to a heat insulation pipe, and a cooling pipe is installed inside the heat insulation pipe. A water pump is connected to the cooling pipe through a water tank, which allows the cooling water to circulate in the cooling pipe, keeping the heat insulation pipe at a low temperature. This avoids the risk of burns to personnel and protects personnel safety. At the same time, it is more convenient for personnel to work and improves work efficiency. It solves the problem that the high-temperature gas discharged from existing centrifugal steam compressors usually causes the pipe to overheat, which can lead to burns if personnel accidentally touch it, and it is also inconvenient for personnel to work.

[0004] As described above, heat is dissipated from the compressed gas by installing heat sinks on the perforated tube and circulating cooling water. However, in this scheme, external dust will fall on the heat sinks, and the adhesion of dust will affect the heat dissipation effect of the heat sinks. In addition, some existing schemes use heat exchangers to dissipate heat. Most heat exchangers use heat sink fins. However, during use, excessive heat will concentrate around the heat sink fins. If this heat is not dissipated quickly, it will eventually damage the heat sink fins, which will ultimately affect the performance of the MVR centrifugal steam compressor. Summary of the Invention

[0012] Preferably, the auxiliary component further includes a stabilizing rod fixedly installed on the two supporting uprights. A first sliding plate and a second sliding plate are slidably installed on the stabilizing rod. Multiple cleaning rods are fixedly installed on both the first and second sliding plates.

[0013] Preferably, a fixing rod is fixedly installed between the two U-shaped frame plates, and symmetrically arranged U-shaped fixed plates are fixedly installed on the fixing rod.

[0018] This invention provides an MVR centrifugal steam compressor. Compared with the prior art, it has the following advantages:

[0019] 1. In this invention, when steam exchanges heat through a heat exchanger, the heat is dissipated by the heat dissipation fins on the heat exchanger. At the same time, the switch of the spray head and the switch of the electric push rod are turned on. The electric push rod drives the U-shaped frame plate to rise. The first and second sets of teeth on the U-shaped frame plate mesh with the reciprocating gear on the rotating shaft in sequence. This causes the reciprocating gear to drive the cooling pipe to swing back and forth through the rotating shaft. The spray head on the cooling pipe will adjust its angle according to the swing of the cooling pipe, so that the spray head sprays cooling water evenly on the heat dissipation fins, thereby promoting the heat dissipation effect of the heat dissipation fins and ultimately improving the overall performance of the steam compressor.

[0020] 2. In this invention, when the U-shaped frame plate is raised, it will simultaneously drive the fixing rod to rise. The U-shaped fixed plate on the fixing rod will drive the first connecting frame and the second connecting frame to rise. The first driving rod and the second driving rod on the first connecting frame and the second connecting frame will rise simultaneously. Then, by utilizing the cooperation between the first driving rod and the L-shaped frame plate on the first slide plate, and the cooperation between the second driving rod and the L-shaped frame plate on the second slide plate, the cleaning rods on the first slide plate and the second slide plate will be limited by the stabilizing rod, thereby cleaning the dust between the heat dissipation fins, ensuring that the heat dissipation fins are not affected by dust, effectively maintaining the cleanliness of the heat dissipation fins, and thus ensuring the efficient operation of the heat exchanger.

[0021] 3. In this invention, the worm gear on the output shaft is driven to rotate by a motor. The worm gear and the driven worm wheel work together. When the driven worm wheel rotates, it drives the fan blades to rotate through the drive shaft. The airflow generated by the fan blades will quickly dissipate the heat dissipation fins and the heat around the heat dissipation fins, effectively enhancing the heat exchanger's performance.

[0022] 4. In this invention, when the worm rotates, it will engage with the worm gear teeth on the support block. The mounting block will adjust its angle on the support block through the engagement of the sliding block and the sliding groove. The fan blades on the mounting block will adjust their angles simultaneously. By adjusting the angle of the fan blades, the airflow generated by the fan blades can more effectively dissipate the heat on the heat dissipation fins, thereby effectively improving the overall performance and efficiency of the steam compressor.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-8 This invention relates to an MVR centrifugal steam compressor, comprising a base plate 1, a support frame 2 fixedly mounted on the base plate 1, an evaporation chamber 3 fixedly mounted on the support frame 2, a first pipe 4 fixedly connected to the evaporation chamber 3, a first fan 5 fixedly connected to the end of the first pipe 4 away from the evaporation chamber 3, a second pipe 6 fixedly connected to the output port of the first fan 5, a heat exchanger 7 disposed at the end of the second pipe 6 away from the first fan 5, a third pipe 8 fixedly connected to one end of the heat exchanger 7, a second fan 9 fixedly connected to the end of the third pipe 8 away from the heat exchanger 7, and a fourth pipe 10 fixedly connected to the output port of the second fan 9. The secondary steam (low pressure and low temperature) generated in the evaporation chamber 3 is drawn in and compressed by the first-stage fan, resulting in a slight increase in temperature and pressure. The compressed steam then enters the second-stage fan after passing through the heat exchanger 7, where it is compressed again to the target pressure / temperature. Finally, the high-temperature steam enters the heater as a heat source, condenses, and flows back to the evaporation chamber 3. Since this technology is well known to those skilled in the art, it will not be described in detail here.

[0034] Heat exchanger 7 is equipped with heat dissipation fins 11, and auxiliary components are provided on the device base plate 1 to improve the heat dissipation effect of the heat dissipation fins 11. The auxiliary components include two support plates 12 fixedly mounted on the device base plate 1, a rotating shaft 13 rotatably mounted between the two support plates 12, a cooling pipe 14 fixedly mounted on the rotating shaft 13, and multiple spray nozzles 15 fixedly connected to the cooling pipe 14. A reciprocating gear 16 is fixedly mounted at the end of the rotating shaft 13. Mounting plates 17 are fixedly mounted on both support plates 12, an electric push rod 18 is fixedly mounted on the mounting plate 17, and a U-shaped frame plate 19 is fixedly mounted on the electric push rod 18. The interior of the U-shaped frame plate 19 is provided with a first mounting surface 20 and a second mounting surface 20. The first mounting surface 20 has a first gear set 22 fixedly mounted on it, and the second mounting surface 21 has a second gear set 23 fixedly mounted on it. The first gear set 22 and the second gear set 23 are arranged in a cross pattern and mesh with the reciprocating gear 16 in sequence. The cooling pipe 14 is located directly above the heat dissipation fins 11. Multiple spray nozzles 15 are evenly distributed. The reciprocating gear 16 is located on the outside of the support plate 12, and the cooling pipe 14 is located on the inside of the support plate 12. The cooling pipe 14 is provided with a water inlet pipe, which facilitates the addition of cooling water to the cooling pipe 14. Since the water inlet pipe is a technology well known to those skilled in the art, it will not be described in detail here.

[0035] In this embodiment, when steam exchanges heat through heat exchanger 7, the heat is dissipated by the heat dissipation fins 11 on heat exchanger 7. At the same time, the switch of spray head 15 and the switch of electric push rod 18 are turned on. The electric push rod 18 drives the U-shaped frame plate 19 to rise. The first tooth set 22 and the second tooth set 23 on the U-shaped frame plate 19 mesh with the reciprocating gear 16 on the rotating shaft 13 in sequence. As a result, the reciprocating gear 16 drives the cooling pipe 14 to swing back and forth through the rotating shaft 13. The spray head 15 on the cooling pipe 14 will adjust its angle according to the swing of the cooling pipe 14. As a result, the spray head 15 sprays cooling water evenly on the heat dissipation fins 11, thereby promoting the heat dissipation effect of the heat dissipation fins 11 and ultimately improving the overall performance of the steam compressor.

[0036] The auxiliary components also include stabilizing rods 24 fixedly mounted on two supporting uprights 12. A first sliding plate 25 and a second sliding plate 26 are slidably mounted on the stabilizing rods 24. Multiple cleaning rods 27 are fixedly mounted on both the first and second sliding plates 25 and 26. Symmetrically arranged L-shaped frame plates 28 are fixedly mounted on the lower surfaces of both the first and second sliding plates 25 and 26. A fixing rod 29 is fixedly mounted between two U-shaped frame plates 19. Symmetrically arranged U-shaped fixed plates 30 are fixedly mounted on the fixing rod 29. A first connecting frame 31 and a second connecting frame 32 are fixedly mounted on the U-shaped fixed plates 30. A first drive rod 33 is rotatably mounted on the first connecting frame 31. A second drive rod 34 is rotatably mounted on the second connecting frame 32. Lifting grooves 35 are provided on both support plates 12. The stabilizing rod 24 is slidably mounted with the lifting grooves 35. The end of the first drive rod 33 away from the first connecting frame 31 is rotatably connected to the L-shaped frame plate 28 on the first slide plate 25. The end of the second drive rod 34 away from the second connecting frame 32 is rotatably connected to the L-shaped frame plate 28 on the second slide plate 26. Multiple cleaning rods 27 are respectively located between the heat dissipation fins 11. By using a single cleaning rod 27 to slide between two heat dissipation fins 11, it is convenient to clean the dust on the heat dissipation fins 11 and ensure the heat dissipation effect of the heat dissipation fins 11.

[0037] In this embodiment, when the U-shaped frame plate 19 is raised, it will simultaneously drive the fixing rod 29 to rise. The U-shaped fixed plate 30 on the fixing rod 29 will drive the first connecting frame 31 and the second connecting frame 32 to rise. The first driving rod 33 and the second driving rod 34 on the first connecting frame 31 and the second connecting frame 32 will rise simultaneously. Then, by utilizing the cooperation between the first driving rod 33 and the L-shaped frame plate 28 on the first slide plate 25, and the cooperation between the second driving rod 34 and the L-shaped frame plate 28 on the second slide plate 26, the cleaning rod 27 on the first slide plate 25 and the second slide plate 26 will be limited by the stabilizing rod 24, thereby cleaning the dust between the heat dissipation fins 11, ensuring that the heat dissipation fins 11 are not affected by dust, effectively maintaining the cleanliness of the heat dissipation fins 11, and thus ensuring the efficient operation of the heat exchanger 7.

[0038] A mounting plate 36 is fixedly installed between two supporting upright plates 12. A support block 37 is fixedly installed on the mounting plate 36. An arc-shaped groove 38 is formed on the support block 37. A worm gear 39 is fixedly installed inside the arc-shaped groove 38. A sliding groove 40 is formed on the outer side of the support block 37. A sliding block 41 is slidably installed on the sliding groove 40. A mounting block 42 is fixedly installed on the sliding block 41. A drive groove 43 is formed on the lower end face of the mounting block 42. A motor 44 is fixedly installed inside the drive groove 43. An output shaft 45 is fixedly installed at the output end of the motor 44. A worm gear 46 is fixedly installed on the output shaft 45. A drive shaft 47 is rotatably installed on the inner top of the drive groove 43. A driven worm gear is fixedly installed on the drive shaft 47. The fan blades 49 and worm gear 48 are driven by the worm gear 46 and the worm wheel 48 is located on one side of the worm 46. The driven worm wheel 48 is driven by the worm 46 and is located inside the drive groove 43. The fan blades 49 are located above the mounting block 42. In order to ensure that the driven worm wheel 48 can drive the fan blades 49 to rotate at a high speed, the number of teeth on the driven worm wheel 48 is several times the number of teeth on the worm 46. This ensures that when the worm 46 rotates one revolution, the driven worm wheel 48 can rotate several revolutions. Since this technology is well known to those skilled in the art, it will not be described in detail here. The motor 44 can rotate in both directions to ensure that the mounting block 42 can be adjusted at an angle on the support block 37.

[0039] In this embodiment, the worm gear 46 on the output shaft 45 is driven to rotate by the motor 44. The worm gear 46 and the driven worm wheel 48 work together, and the driven worm wheel 48 drives the fan blades 49 to rotate via the drive shaft 47. The airflow generated by the fan blades 49 quickly dissipates the heat dissipation fins 11 and the heat around them, effectively enhancing the performance of the heat exchanger 7. When the worm gear 46 rotates, it engages with the worm wheel teeth 39 on the support block 37. The mounting block 42 adjusts its angle on the support block 37 through the engagement of the sliding block 41 and the sliding groove 40. The fan blades 49 on the mounting block 42 adjust their angle simultaneously. By adjusting the angle of the fan blades 49, the airflow generated by the fan blades 49 more effectively dissipates the heat on the heat dissipation fins 11, effectively improving the overall performance and efficiency of the steam compressor.

[0040] Working principle:

[0041] During use, the secondary steam (low pressure and low temperature) generated in the evaporation chamber 3 is drawn in and compressed by the first-stage fan, and the temperature and pressure rise slightly. The compressed steam enters the second-stage fan after passing through the heat exchanger 7, and is compressed again to the target pressure / temperature. Finally, the high-temperature steam enters the heater as a heat source, and after condensation, it flows back to the evaporation chamber 3.

[0042] When steam exchanges heat through heat exchanger 7, the heat is dissipated by the heat dissipation fins 11 on heat exchanger 7. At the same time, the switch of spray head 15 and the switch of electric push rod 18 are turned on. The electric push rod 18 drives the U-shaped frame plate 19 to rise. The first tooth set 22 and the second tooth set 23 on the U-shaped frame plate 19 mesh with the reciprocating gear 16 on the rotating shaft 13 in sequence. The reciprocating gear 16 drives the cooling pipe 14 to swing back and forth through the rotating shaft 13. The spray head 15 on the cooling pipe 14 will adjust its angle according to the swing of the cooling pipe 14. The spray head 15 sprays cooling water evenly on the heat dissipation fins 11, thereby promoting the heat dissipation effect of the heat dissipation fins 11.

[0043] When the U-shaped frame plate 19 is raised, it will simultaneously drive the fixing rod 29 to rise. The U-shaped fixed plate 30 on the fixing rod 29 will drive the first connecting frame 31 and the second connecting frame 32 to rise. The first drive rod 33 and the second drive rod 34 on the first connecting frame 31 and the second connecting frame 32 will rise simultaneously. Then, by utilizing the cooperation between the first drive rod 33 and the L-shaped frame plate 28 on the first slide plate 25, and the cooperation between the second drive rod 34 and the L-shaped frame plate 28 on the second slide plate 26, the cleaning rod 27 on the first slide plate 25 and the second slide plate 26 will be limited by the stabilizing rod 24, thereby cleaning the dust between the heat dissipation fins 11, ensuring that the heat dissipation fins 11 are not affected by dust, and effectively maintaining the cleanliness of the heat dissipation fins 11.

[0044] The motor 44 drives the worm gear 46 on the output shaft 45 to rotate. The worm gear 46 and the driven worm wheel 48 work together. When the driven worm wheel 48 rotates, it drives the fan blades 49 to rotate through the drive shaft 47. The airflow generated by the fan blades 49 quickly dissipates the heat dissipation fins 11 and the heat around them, effectively enhancing the performance of the heat exchanger 7. When the worm gear 46 rotates, it engages with the worm wheel teeth 39 on the support block 37. The mounting block 42 adjusts its angle on the support block 37 through the engagement of the sliding block 41 and the sliding groove 40. The fan blades 49 on the mounting block 42 adjust their angle simultaneously. By adjusting the angle of the fan blades 49, the airflow generated by the fan blades 49 can more effectively dissipate the heat on the heat dissipation fins 11, effectively improving the performance and efficiency of the entire steam compressor.
