Technical Field
[0001] This invention relates to the field of steam mechanical recompression technology, specifically to a centrifugal compressor MVR booster system. Background Technology
[0002] Mechanical vapor recompression (MVR) booster systems are highly efficient heat recovery technologies primarily used for the production of industrial steam and hot water. This system utilizes a centrifugal compressor to compress low-pressure steam to a high-pressure state, thereby increasing its temperature and energy density. The compressed steam is then fed into a heat exchanger to exchange heat with cold water, recovering the heat from the steam to generate high-temperature hot water or steam for industrial processes or heating. This cyclical process not only improves energy utilization efficiency but also reduces energy consumption and operating costs, resulting in significant economic and environmental benefits. MVR booster systems are widely used in industries such as chemical, food, and pharmaceutical, and are one of the effective means to achieve sustainable development.
[0003] Currently, traditional centrifugal compressor MVR booster systems have significant shortcomings in steam generation and heat exchange. First, most systems are open-loop, with high-temperature condensate being directly discharged, resulting in substantial sensible heat loss and low energy utilization. Second, the heat exchanger lacks an effective airflow distribution structure, leading to uneven distribution of high-temperature, high-pressure steam, causing localized overheating or undercooling. This not only reduces heat exchange efficiency but also easily causes thermal stress concentration in the heat exchange tubes, potentially leading to pipeline fatigue damage or compressor surge over long-term operation. Furthermore, uneven contact between steam and heat exchange tubes causes fluctuations in the compressor's booster load, resulting in poor system stability, increased failure rate, and overall energy efficiency failing to meet industrial energy conservation requirements.

[0018] This invention provides a centrifugal compressor MVR booster system. Compared with the prior art, it has the following advantages:
[0019] 1. In this invention, a steam generator produces steam by heating water. The steam is then transported to a centrifugal compressor through an outlet pipe. The centrifugal compressor uses its rotating components to rotate the steam at high speed, thereby increasing the steam's pressure and temperature. The compressed high-temperature, high-pressure steam is discharged from the centrifugal compressor's exhaust port and transported to a heat exchanger body through an exhaust pipe. In the heat exchanger body, the high-temperature steam exchanges heat with the incoming cold water. The internal heat exchange tubes of the heat exchanger body effectively transfer the steam's heat to the cold water, thus heating the cold water. At this time, the steam releases some heat, reducing its temperature and pressure, and condenses into water. The heated cold water is discharged through a cold water outlet pipe, becoming hot water. This hot water can be used in other industrial processes or heating systems. The condensed water is introduced into a recirculation pump through a drain pipe. The recirculation pump pumps the water back and sends it back to the steam generator through a connecting pipe. This recirculation process helps improve energy utilization and reduce energy consumption.
[0020] 2. In this invention, when high-temperature and high-pressure steam enters the heat exchanger body through the exhaust pipe, the external gear ring is driven to rotate by the drive motor. When the external gear ring rotates, it drives the auxiliary stationary plate to rotate at high speed through the connecting frame plate. When the auxiliary stationary plate rotates, it drives the rotating blades and guide arc plates to rotate through the cooperation of the drive rod and the adjustment component. The rotating guide arc plates can make the airflow discharged from the exhaust pipe evenly distributed into the heat exchanger body. At the same time, the airflow generated by the rotating blades can make the distributed high-temperature and high-pressure steam evenly contact the heat exchange tubes, avoiding local overheating or cooling, improving the efficiency of heat exchange, and improving the overall efficiency of the MVR booster system.
[0021] 3. In this invention, a hydraulic cylinder drives an adjusting block to move horizontally within the outer casing. The bearing and adjusting slide on the adjusting block move synchronously. By utilizing the limiting position of the adjusting slide and the drive rod, as well as the positioning and sliding of the stabilizing groove and the stabilizing slider, the adjusting slide ensures that the adjusting slide drives the rotating blade to adjust its position. The adjusting slide can utilize the positioning between the stabilizing groove and the stabilizing slider to keep the rotating blade in a rotating state. The position-adjustable and rotating blade not only improves the uniformity of high-temperature and high-pressure steam, but also enhances the efficiency of heat exchange, thereby improving the overall operating efficiency of the equipment.
[0022] 4. In this invention, when the adjusting slide cylinder moves horizontally, it drives the linkage push rod to move. The linkage push rod drives the auxiliary slip ring on the positioning crossbar to adjust its position. By utilizing the sliding contact between the pushing vertical rod and the guide arc plate on the auxiliary slip ring, the installation of the auxiliary fixed block and the guide arc plate, and the limiting of the reset rotating rod 35 on the auxiliary fixed block, the guide arc plate can be extended outward with the reset rotating rod 35 as the center. When the auxiliary slip ring reciprocates on the positioning crossbar, the extended guide arc plate can be restored to its original position by the reaction force of the reset torsion spring. Through the cooperation of the angle-adjustable guide arc plate and the far cone head, efficient heat exchange between high-temperature and high-pressure steam and heat exchange tubes is ensured, which greatly improves the energy utilization rate and reduces the energy consumption of the entire system.

[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 Figures 1-8This invention relates to a 5MVR centrifugal compressor booster system, comprising a device base 1, a steam generator 2 fixedly mounted on the device base 1, an outlet pipe 3 fixedly connected to the steam generator 2, a front support 4 fixedly mounted on the device base 1, a centrifugal compressor 5 fixedly mounted on the front support 4, an exhaust pipe 6 fixedly connected to the outlet of the centrifugal compressor 5, and symmetrically arranged rear supports 7 fixedly mounted on the device base 1 and to one side of the front support 4, a heat exchanger body 8 fixedly mounted on the rear support 7, a stabilizing frame 9 fixedly mounted on the rear support 7, a recirculation pump 10 fixedly mounted on the stabilizing frame 9, a drain pipe 11 fixedly connected to the inlet of the recirculation pump 10, and a connecting pipe 12 fixedly connected to the outlet of the recirculation pump 10. The heat exchanger body 8 includes... The outer casing 801 has a left cover 802 and a right cover 803 fixedly installed at its two ends. A cold water inlet pipe 804 and a cold water outlet pipe 805 are fixedly connected to the right cover 803. A heat exchange pipe 806 is fixedly connected to the cold water inlet pipe 804 and the cold water outlet pipe 805. The end of the exhaust pipe 3 away from the steam generator 2 is connected to the air inlet of the centrifugal compressor 5. The end of the exhaust pipe 6 away from the centrifugal compressor 5 passes through the left cover 802 and extends into the interior of the outer casing 801. The ends of the cold water inlet pipe 804 and the cold water outlet pipe 805 near the right cover 803 both extend into the interior of the outer casing 801. The heat exchange pipe 806 is located inside the outer casing 801. The end of the connecting pipe 12 away from the recirculation pump 10 is connected to the steam generator 2.
[0034] In operation, the steam generator 2 heats water to produce steam, which is then transported to the centrifugal compressor 5 through the outlet pipe 3. The steam enters the inlet of the centrifugal compressor 5, where its rotating components rotate the steam at high speed, increasing the steam's pressure and temperature. The compressed high-temperature, high-pressure steam is discharged from the outlet of the centrifugal compressor 5 and transported to the heat exchanger body 8 through the exhaust pipe 6. In the heat exchanger body 8, the high-temperature steam exchanges heat with the incoming cold water. The internal heat exchange tubes 806 of the heat exchanger body 8 effectively transfer the steam's heat to the cold water, thus heating the cold water. At this time, the steam releases some heat, lowering its temperature and pressure, and condenses into water. The heated cold water is discharged through the cold water outlet pipe 805, becoming hot water. This hot water can be used in other industrial processes or heating systems. The condensed water is introduced into the recirculation pump 10 through the drain pipe 11. The recirculation pump 10 pumps the water back and sends it back to the steam generator 2 through the connecting pipe 12. This recirculation process helps improve energy utilization and reduce energy consumption.

An external gear ring 16 is rotatably mounted between the left cover 802 and the outer shell 801. A connecting frame plate 17 is fixedly mounted on the inner side of the external gear ring 16. An auxiliary stationary plate 18 is fixedly mounted on the connecting frame plate 17. A drive rotating rod 19 is fixedly mounted on one side of the auxiliary stationary plate 18. An adjustment assembly is provided inside the outer shell 801. The adjustment assembly is provided with rotating blades 20 and multiple guide vanes. The flow guide vane 21 and the drive gear 15 are located outside the outer gear ring 16 and mesh with it. The rotating blade 20 is located inside the heat exchange tube 806, and the flow guide vane 21 is located at the outlet of the exhaust pipe 6. The gear ratio between the drive gear 15 and the outer gear is 1:2, and this gear ratio can be adjusted according to the needs of the personnel. At the same time, there is a sealing ring between the outer gear ring 16, the left cover 802, and the outer shell 801. This sealing ring ensures the effectiveness of the heat exchanger body 8 during operation. Since the sealing ring is a technology well known to those skilled in the art, it will not be described in detail here.
[0036] In this embodiment, when high-temperature and high-pressure steam enters the heat exchanger body 8 through the exhaust pipe 6, the external gear ring 16 is driven to rotate by the drive motor 14. When the external gear ring 16 rotates, it drives the auxiliary stationary plate 18 to rotate at high speed through the connecting frame plate 17. When the auxiliary stationary plate 18 rotates, it drives the rotating blade 20 and the guide arc plate 21 to rotate through the cooperation of the drive rod 19 and the adjustment component. The rotating guide arc plate 21 can make the airflow discharged from the exhaust pipe 6 evenly disperse into the heat exchanger body 8. At the same time, the airflow generated by the rotating blade 20 can make the dispersed high-temperature and high-pressure steam evenly contact the heat exchange tube 806, avoid local overheating or cooling, improve the efficiency of heat exchange, and further improve the overall efficiency of the MVR booster system.
[0037] The adjustment assembly includes a hydraulic cylinder 22 fixedly mounted on the right cover 803. An adjustment block 23 is fixedly mounted on the output shaft of the hydraulic cylinder 22. A bearing 24 is fixedly mounted on the adjustment block 23. An adjustment slide cylinder 25 is fixedly mounted on the bearing 24.

A rotating blade 20 is fixedly mounted on the adjustment slide cylinder 25. The adjustment slide cylinder 25 is slidably mounted on the drive rod 19. The stabilizing slider 27 is slidably mounted on the stabilizing groove 26.
[0038] In this embodiment, the hydraulic cylinder 22 drives the adjusting block 23 to move horizontally within the outer casing 801. The bearing 24 and the adjusting slide 25 on the adjusting block 23 move synchronously. By utilizing the limiting position of the adjusting slide 25 and the drive rod 19, and the positioning and sliding of the stabilizing groove 26 and the stabilizing slider 27, the adjusting slide 25 is ensured to drive the rotating blade 20 to adjust its position.

[0040] In this embodiment, when the adjusting slide 25 moves horizontally, it drives the linkage push rod 38 to move. The linkage push rod 38 drives the auxiliary slip ring 39 on the positioning crossbar 31 to adjust its position.

When the auxiliary slip ring 39 reciprocates on the positioning crossbar 31, the extended guide arc plate 21 can be restored to its original position by the reaction force of the reset torsion spring 37. Through the cooperation of the angle-adjustable guide arc plate 21 and the far cone head, the high-temperature and high-pressure steam and the heat exchange tube 806 are ensured to achieve efficient heat exchange, which greatly improves the energy utilization rate and reduces the energy consumption of the entire system.
[0041] Working principle: During operation, the steam generator 2 heats water to produce steam, which is then transported to the centrifugal compressor 5 through the outlet pipe 3. The steam enters the inlet of the centrifugal compressor 5. The centrifugal compressor 5 uses its rotating components to rotate the steam at high speed, thereby increasing the steam pressure and temperature. The compressed high-temperature, high-pressure steam is discharged from the exhaust port of the centrifugal compressor 5 and transported to the heat exchanger body 8 through the exhaust pipe 6. In the heat exchanger body 8, the high-temperature steam exchanges heat with the incoming cold water.The internal heat exchange tubes 806 of the heat exchanger body 8 effectively transfer the heat of the steam to the cold water, thereby heating the cold water. At this time, the steam releases some heat, reduces its temperature and pressure, and condenses into water. The heated cold water is discharged through the cold water outlet pipe 805, becoming hot water. This hot water can be used in other industrial processes or heating systems. The condensed water is introduced into the recirculation pump 10 through the drain pipe 11. The recirculation pump 10 pumps the water back and sends it back to the steam generator 2 through the connecting pipe 12. This recirculation process helps to improve energy utilization. When high-temperature and high-pressure steam enters the heat exchanger body 8 through the exhaust pipe 6, it drives the external gear ring 16 to rotate through the drive motor 14. When the external gear ring 16 rotates, it drives the auxiliary stationary plate 18 to rotate at high speed through the connecting frame plate 17. When the auxiliary stationary plate 18 rotates, it drives the rotating blades 20 and the guide arc plate 21 to rotate through the cooperation of the drive rod 19 and the adjusting component. The rotating guide arc plate 21 can make the airflow discharged from the exhaust pipe 6 evenly distributed into the heat exchanger body 8. At the same time, the airflow generated by the rotating blades 20 can make the high-temperature and high-pressure steam evenly contact the heat exchange tube 806, avoiding local overheating or cooling and improving the heat exchange efficiency. The hydraulic cylinder 22 drives the adjusting block 23 to move horizontally within the outer shell 801. The bearing 24 on the adjusting block 23 and the adjusting... The adjusting slide cylinder 25 moves synchronously. By utilizing the limiting positions of the adjusting slide cylinder 25 and the drive rotating rod 19, and the positioning sliding of the stabilizing groove 26 and the stabilizing slider 27, the adjusting slide cylinder 25 ensures that the rotating blade 20 is always in a rotating state, driven by the positioning between the stabilizing groove 26 and the stabilizing slider 27. The adjustable and rotating rotating blade 20 not only improves the uniformity of high-temperature and high-pressure steam but also enhances the efficiency of heat exchange, thus improving the overall operating efficiency of the equipment. When the adjusting slide cylinder 25 moves horizontally, it drives the connecting push rod 38 to move. The drive of the connecting push rod 38 enables the auxiliary... The position of the slip ring 39 is adjusted by utilizing the sliding contact between the push rod 40 on the auxiliary slip ring 39 and the guide arc plate 21, the installation of the auxiliary fixed block 36 and the guide arc plate 21, and the limiting of the reset rotating rod 35 on the auxiliary fixed block 36. This allows the guide arc plate 21 to unfold outward with the reset rotating rod 35 as the center. When the auxiliary slip ring 39 reciprocates on the positioning horizontal bar 31, the unfolded guide arc plate 21 can be restored to its original position by the reaction force of the reset torsion spring 37. Through the cooperation of the angle-adjustable guide arc plate 21 and the far cone head, efficient heat exchange between high-temperature and high-pressure steam and heat exchange tube 806 is ensured, which greatly improves the energy utilization rate and reduces the energy consumption of the entire system.
