Description

Technical Field

[0001] The invention relates to the field of screw compressors, and in particular to a skid-mounted screw compressor for argon recovery. Background Art

[0002] "Skid-mounted" is a way of installing equipment, which means that the equipment or system is installed on a base (skid). The screw compressor is a positive displacement compressor that compresses gas through a pair of intermeshing screws (commonly called rotors). When the screws rotate, they form sealed chambers at the suction end. As the screws rotate, these chambers gradually reduce in volume, thereby compressing the gas. The compressed gas is discharged through the exhaust end. During the compression process, the purity of the argon gas can be further improved through the filtration and purification system to ensure that it meets the requirements of specific applications and to achieve recovery or use of the argon gas.

[0003] As the screw compressor compresses argon, the internal energy of the gas increases, causing the temperature of the gas discharged from the exhaust end to usually increase. If not intervened in time, it will cause subsequent equipment damage or aging. Due to the variability of the external environment, such as the different initial temperatures and pressures of argon entering the screw compressor, these will cause different temperatures of the compressed argon. Existing screw compressors are not convenient for adaptive cooling based on the temperature of the compressed argon to reduce it to a safe temperature range. Summary of the invention

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. During the operation of the screw compressor body, the detection unit monitors the temperature of the argon passing through the exhaust pipe. When the monitored argon temperature is lower than the preset temperature threshold, a first temperature information value is generated. The control system controls the blower mechanism to blow out airflow to take away the heat on the surface of the heat exchange tube, and cools down the argon flowing through the heat exchange tube to meet the specified recovery temperature. Due to the variability of the external environment, such as the different initial temperatures and pressures of the argon entering the screw compressor body, these will often cause the compressed argon temperature to be too high, and the temperature cannot be reduced to a safe temperature range by a simple airflow. Therefore, when the detection unit detects that the temperature value after compression reaches or exceeds the set threshold, a second temperature information value is generated. The control system controls the blower mechanism to continue to operate while also controlling the heat dissipation enhancement mechanism to operate. With the help of the heat dissipation enhancement mechanism, the blower mechanism is assisted to take away the heat on the surface of the heat exchange tube, which is conducive to accelerating the cooling speed of the argon, so that it can be reduced to a safe temperature range, thereby avoiding the subsequent equipment damage or aging caused by the temperature increase caused by compression; the temperature of the argon is monitored by the set detection unit, and the control system is used to perform adaptive cooling operations to speed up work efficiency and reduce work energy consumption.

[0045] 2. After the control system controls the switching mechanism and the water supply unit to start, and after the four arc-shaped shells gather to form an annular structure, it also controls the second motor to start. The output shaft of the second motor will drive the second gear to rotate. Since the second gear is meshed with the second outer gear ring, the second outer gear ring connected to the surface of the second annular shell will be driven to rotate while the second gear rotates, thereby realizing the rotation of the second annular shell relative to the circular tube. The rotating second annular shell, connected with the four sets of telescopic rods, synchronously drives the four arc-shaped shells that are gathered to rotate. The arc-shaped opening at the end of the arc-shaped shell will slide over the end surface of the cylinder as the arc-shaped shell rotates. By rotating the four arc-shaped shells that are gathered, it is beneficial to expand the spraying area of ​​the atomized water droplets, further reduce the atomization dead angle, and help to fully take away the heat from the surface of the heat exchange tube with the evaporation of water droplets, thereby improving the heat exchange efficiency.

DETAILED DESCRIPTION

[0060] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0061] like Figures 1 to 13A skid-mounted screw compressor for argon recovery shown in the figure comprises a base 1, a screw compressor body 2 is fixedly mounted on the top of the base 1, a suction end 201 and an exhaust end 202 are arranged on the screw compressor body 2, and further comprises:

[0062] An exhaust pipe 3, the exhaust pipe 3 is fixedly connected to the exhaust end 202;

[0063] A detection unit, arranged on the exhaust pipe 3, for monitoring the temperature of the compressed argon gas;

[0064] The support frame 4 is fixedly connected to the side wall of the base 1, and the top of the support frame 4 is fixedly connected to a round tube 5 through two support seats;

[0065] The heat exchanger is fixedly arranged inside the circular tube 5 by two supports. The heat exchanger is composed of a circular shell 6 at both ends and a plurality of heat exchange tubes 7. The circular shell 6 near the exhaust end 202 of the heat exchanger is fixedly connected to the exhaust pipe 3.

[0066] The blower mechanism is arranged inside the circular tube 5 and removes the heat on the surface of the heat exchange tube 7 by blowing out air flow;

[0067] The heat dissipation enhancement mechanism is arranged inside the round tube 5 and is used to assist the air blowing mechanism in removing the heat from the surface of the heat exchange tube 7;

[0068] The control system controls the heat dissipation enhancement mechanism to assist the blowing mechanism to take away the heat from the surface of the heat exchange tube 7 according to the temperature value detected by the detection unit; during operation, the argon gas in the external environment is sucked into the screw compressor body 2 from the suction end 201 on the screw compressor body 2 for compression, and the compressed argon gas is discharged through the exhaust pipe 3 at the exhaust end 202, and the argon gas discharged from the exhaust pipe 3 is subjected to heat exchange operation through multiple heat exchange tubes 7 of the heat exchanger, thereby reducing the temperature of the compressed argon gas, and avoiding the subsequent equipment damage or aging caused by the temperature increase of the argon gas due to compression. The detection unit is specifically a temperature sensor. During the operation of the screw compressor body 2, the detection unit monitors the temperature of the argon gas passing through the exhaust pipe 3. When the monitored argon gas temperature is lower than the preset temperature threshold, a first temperature information value is generated, and the control system controls the blowing separately. The air flow blown out by the mechanism takes away the heat from the surface of the heat exchange tube 7, and cools the argon gas flowing through the heat exchange tube 7 to meet the specified recovery temperature. Due to the variability of the external environment, such as the different initial temperatures and pressures of the argon gas entering the screw compressor body 2, these will often cause the compressed argon gas to be too hot, and the temperature cannot be reduced to a safe temperature range by a simple airflow. Therefore, when the detection unit monitors that the temperature value after compression reaches or exceeds the set threshold, a second temperature information value is generated. The control system controls the air blowing mechanism to continue operating while also controlling the heat dissipation enhancement mechanism to operate. The heat dissipation enhancement mechanism assists the air blowing mechanism in taking away the heat from the surface of the heat exchange tube 7, which is beneficial to speed up the cooling speed of the argon gas so that it can be reduced to a safe temperature range, thereby avoiding subsequent equipment damage or aging due to the temperature increase caused by compression.

[0069] As an embodiment of the present invention, the hair dryer mechanism comprises:

[0070] Two annular plates 8 are rotatably connected to the surfaces of the two circular shells 6, respectively. The two annular plates 8 are rotatably connected to the inner wall of the circular tube 5. Two exhaust fans 9 are fixedly installed on the annular plates 8 away from the exhaust pipe 3.

[0071] Four blowing components, which are distributed in a circular array inside the circular tube 5, each of which includes two sliding plates 10, which are respectively slidably connected to the opposite side walls of the two circular shells 6, and a storage shell 11 is fixedly connected between the two sliding plates 10, and a plurality of air outlet holes 12 are opened on the surface of the storage shell 11;

[0072] Two first annular shells 13 are symmetrically fixedly connected to the surface of the circular tube 5. The inner wall of each first annular shell 13 is fixedly connected with four first telescopic tubes 14 in a circumferential array. The ends of all the first telescopic tubes 14 extend to the inside of the circular tube 5 and are fixedly connected with the adjacent storage shells 11.

[0073] The blower 15 is fixedly installed on the top of the support frame 4. A three-way pipe is fixedly connected to the air outlet pipe of the blower 15. The two ends of the three-way pipe are respectively fixedly connected to the delivery pipes 16. The two delivery pipes 16 are respectively fixedly connected to the two first annular shells 13. When working, the control system controls the blower 15 and the exhaust fan 9 to start. The blower 15 uses the three-way pipe connected to the delivery pipe 16 to transport air to the inside of the two first annular shells 13. The airflow entering the first annular shell 13 will pass through the first telescopic tube 14 on the inner wall thereof and stay in the four storage shells 11. Then, it will be ejected from the multiple air outlet holes 12 on the surface of the storage shell 11. The ejected airflow will be dispersed into the inside of the circular tube 5. As the exhaust fan 9 exhausts the inside of the circular tube 5, the airflow will be discharged through the exhaust fan 9. In the process of the airflow inside the circular tube 5 being discharged outward by the exhaust fan 9, the flowing airflow will take away the heat on the surface of the heat exchange tube 7, thereby realizing heat exchange and cooling the argon gas.

[0074] As an embodiment of the present invention, the heat dissipation enhancement mechanism includes:

[0075] The switching mechanism is used to gather the airflow blown out by the blower mechanism and blow it toward the surface of the heat exchange tube 7 located in the middle position;

[0076] An annular opening is provided through the middle of the circular tube 5, and the annular opening divides the circular tube 5 into a first tube and a second tube. A second annular shell 17 is provided in the annular opening, and two sides of the second annular shell 17 are rotatably connected to the opposite ends of the first tube and the second tube, respectively. The end of the second annular shell 17 is rotatably connected to a rotating ring plate 1701, and a water delivery pipe is fixedly connected to the rotating ring plate 1701, and the water delivery pipe is fixedly connected to the water supply unit;

[0077] Four groups of telescopic rods 18 are fixedly connected to the inner ring wall of the second annular shell 17 in a circumferential array, and the piston rod end of each group of telescopic rods 18 is commonly fixedly connected to an arc shell 19, and a plurality of atomizing nozzles 20 are installed on the inner ring wall of each arc shell 19;

[0078] Four second telescopic tubes 21 are fixedly connected to the inner wall of the second annular shell 17 in a circumferential array, and the ends of the four second telescopic tubes 21 are fixedly connected to the four arc-shaped shells 19 respectively;

[0079] Pulling mechanism, during the operation of the switching mechanism, the linkage pulling mechanism drives the four arc-shaped shells 19 to gather toward the middle to form a ring structure; during operation, when the detection unit monitors that the temperature value after compression reaches or exceeds the set threshold, the airflow cannot reduce the temperature to a safe temperature range, so the control system controls the blowing mechanism to continue to operate while also controlling the switching mechanism and the water supply unit to start. The operation of the switching mechanism drives the four storage shells 11 to move toward the middle and gather together, so that the gathered storage shells 11 are inserted next to the heat exchange tube 7 near the middle position, so that the airflow blown out of the storage shell 11 is conveniently introduced into the surface of the heat exchange tube 7 at the middle position, and the exhausted airflow after gathering diverges outward, passing through the surface of the heat exchange tube 7 at the middle position, and then It is convenient for the airflow to fully contact the surfaces of the multiple heat exchange tubes 7, thereby improving the heat conversion efficiency. The water supply unit is provided to facilitate the delivery of cooling water to the inside of the second annular shell 17 through the water pipe. The cooling water entering the inside of the second annular shell 17 flows into the inside of the four arc-shaped shells 19 through the four second telescopic tubes 21, and is sprayed out through the multiple atomizing nozzles 20 on the inner ring wall of the arc-shaped shell 19. The cooling water is atomized into fine water droplets by the atomizing nozzles 20 and sprayed onto the surface of the heat exchange tube 7. These water droplets evaporate on the surface of the heat exchange tube 7 and absorb heat, thereby reducing the temperature of the argon passing through the heat exchange tube 7. On the basis of heat dissipation by airflow, heat is dissipated by spraying water mist, which is beneficial to improving the heat exchange efficiency, facilitating timely cooling of the high-temperature argon, and facilitating the handling of argon at different temperatures.

[0080] The pulling mechanism is provided to facilitate the four arc-shaped shells 19 to gather together to form a ring in the middle when the switching mechanism drives the four storage shells 11 to move together, thereby shortening the distance between the atomizing nozzle 20 and the heat exchange tube and reducing the atomization dead angle range. The second telescopic tube 21 and the telescopic rod 18 are provided to extend or shorten axially as the four arc-shaped shells 19 gather or expand.

[0081] The water supply unit includes a water supply tank and a water pump installed on the side wall of the water supply tank. The cooling water inside the water supply tank is transported to the second annular shell 17 through a water pipe by the water pump. The water supply principle of the water supply unit here is the operation method in the prior art, which will not be elaborated in detail and is not illustrated in the figure. By fixing the water pipe on the rotating ring plate 1701 and fixing the water pipe to the water supply unit, if the second annular shell 17 rotates later, the rotating ring plate 1701 can be fixed relative to the second annular shell 17.

[0082] As an embodiment of the present invention, the switching mechanism includes:

[0083] Two driving mechanisms, used to drive the two annular plates 8 to rotate;

[0084] Two groups of guide components are respectively arranged on the side walls of the two annular plates 8, and together drive the four storage shells 11 to move toward the middle and gather together. Each guide component includes four guide grooves 22, and the four guide grooves 22 are arranged in a circular array on the side wall of the annular plate 8. The inner walls of the four guide grooves 22 are all inserted with sliding pins 23, and each sliding pin 23 is respectively connected to the side wall of the adjacent sliding plate 10 for rotation. When working, the control system controls the operation of the two driving mechanisms, and the two driving mechanisms drive the two annular plates 8 to rotate ninety degrees. During the rotation of the annular plate 8, the groove wall of the guide groove 22 will push the end of the sliding pin 23, so that the end of the sliding pin 23 is forced to drive the sliding plate 10 to slide along the side wall of the circular shell 6 The sliding sliding plate 10 drives the storage shell 11 to move synchronously. Therefore, during the rotation of the annular plate 8, the four storage shells 11 are moved to the middle and gathered together by means of the cooperation between the four guide grooves 22 on its surface and the corresponding sliding pins 23, so that the gathered storage shells 11 are inserted next to the heat exchange tube 7 near the middle position, which is convenient for introducing the airflow blown out of the storage shell 11 into the surface of the heat exchange tube 7 at the middle position, and facilitating the full contact of the airflow with the surfaces of multiple heat exchange tubes 7, thereby improving the heat conversion efficiency and avoiding the airflow failing to contact the surface of the heat exchange tube 7 located in the middle position in time and being discharged by the exhaust fan 9, thereby causing the heat on the surface of the heat exchange tube 7 installed in the middle position to not be fully taken away, affecting the cooling effect.

[0085] As an embodiment of the present invention, the driving mechanism includes a first outer gear ring 24 and a first motor 25. The first outer gear ring 24 is fixedly connected to the side wall of the annular plate 8. The first motor 25 is fixedly connected to the inner wall of the circular tube 5 through a mounting plate. The end of the output shaft of the first motor 25 is fixedly connected to a first gear 26, and the first gear 26 is meshed with the first outer gear ring 24. When working, the first motor 25 is started through the control system, and the output shaft of the first motor 25 will drive the first gear 26 to rotate a specified number of circles. Since the first gear 26 is meshed with the first outer gear ring 24, the rotating first gear 26 will drive the first outer gear ring 24 connected to the side wall of the annular plate 8 to rotate, thereby driving the first outer gear ring 24 to rotate ninety degrees along the inner wall of the circular tube 5.

[0086] As an embodiment of the present invention, the pulling mechanism includes eight connecting frames 27, which are fixedly connected to the side walls of the eight sliding plates 10 respectively, and a cylinder 28 is rotatably connected to the side wall of each connecting frame 27. The four arc-shaped shells 19 are provided with arc-shaped openings 29 at both ends, and the ends of the eight cylinders 28 are respectively inserted into the inside of the adjacent arc-shaped openings 29; when working, in the process of the sliding plate 10 moving along the side wall of the annular shell, the moving sliding plate 10 drives the cylinder 28 to move synchronously with the help of the connecting frame 27, and the moving cylinder 28 pushes the inner wall of the arc-shaped opening 29, thereby driving the arc-shaped shell 19 to move and pulling the second telescopic tube 21 and the telescopic rod 18 to extend. Therefore, when all the sliding plates 10 move to the middle and gather together, the synchronously moving cylinder 28 pushes the inner wall of the corresponding arc-shaped opening 29, thereby prompting the four arc-shaped shells 19 to move to the middle and gather together to form an annular structure, shortening the distance between the atomizing nozzle 20 and the heat exchange tube, and reducing the atomization dead angle range.

[0087] As an embodiment of the present invention, the heat dissipation enhancement mechanism also includes a second outer gear ring 30 and a second motor 31. The second outer gear ring 30 is fixedly connected to the surface of the second annular shell 17. The second motor 31 is fixedly installed on the top of the support frame 4. The output shaft end of the second motor 31 is fixedly connected to the second gear 32. The second gear 32 is meshed with the second outer gear ring 30. The control system is also used to control the operation of the second motor 31. When working, the control system controls the switching mechanism and the water supply unit to start, and after the four arc-shaped shells 19 gather to form a ring structure, it also controls the second motor 31 to start. The output shaft of the second motor 31 will drive the second gear 32 to rotate. Since the second gear 32 is meshed with the first The two outer gear rings 30 mesh with each other, so when the second gear 32 rotates, the second outer gear ring 30 connected to the surface of the second annular shell 17 will be driven to rotate, so that the second annular shell 17 can rotate relative to the circular tube 5. The rotating second annular shell 17, connected with the four sets of telescopic rods 18, synchronously drives the four gathered arcuate shells 19 to rotate. The arcuate opening 29 at the end of the arcuate shell 19 will slide over the end surface of the cylinder 28 as the arcuate shell 19 rotates. By rotating the four gathered arcuate shells 19, it is beneficial to expand the spraying area of ​​the atomized water droplets, further reduce the atomization dead angle, and help to fully take away the heat on the surface of the heat exchange tube 7 with the help of water droplet evaporation, thereby improving the heat exchange efficiency.

[0088] As an embodiment of the present invention, the control system includes a controller, and the controller is arranged on the side wall of the support frame 4. The monitoring process of the detection unit includes the following steps:

[0089] When the argon gas temperature monitored by the detection unit is lower than a preset threshold, a first temperature information value is generated;

[0090] The detection unit sends the first temperature information value to the control system to control the blower mechanism to blow out air to take away the heat on the surface of the heat exchange tube 7;

[0091] When the argon gas temperature monitored by the detection unit reaches or exceeds a set threshold, a second temperature information value is generated;

[0101] Working principle of the present invention: argon gas in the external environment is sucked into the screw compressor body 2 from the suction end 201 on the screw compressor body 2 for compression, and the compressed argon gas is discharged through the exhaust pipe 3 of the exhaust end 202, and the argon gas discharged from the exhaust pipe 3 is subjected to heat exchange operation through multiple heat exchange tubes 7 of the heat exchanger, thereby reducing the temperature of the compressed argon gas, and avoiding the subsequent equipment damage or aging caused by the temperature increase of the argon gas due to compression. The detection unit provided is specifically a temperature sensor. During the operation of the screw compressor body 2, the detection unit monitors the temperature of the argon gas passing through the exhaust pipe 3. When the monitored argon gas temperature is lower than the preset temperature threshold, a first temperature information value is generated, and the control system independently controls the blower mechanism to blow out an airflow to take away the heat on the surface of the heat exchange tube 7, and to cool the argon gas flowing through The argon gas in the heat exchange tube 7 is cooled to meet the specified recovery temperature. Due to the variability of the external environment, such as the different initial temperatures and pressures of the argon gas entering the screw compressor body 2, these will often cause the compressed argon gas to be too hot, and the temperature cannot be reduced to a safe temperature range by simple airflow. Therefore, when the detection unit monitors that the temperature value after compression reaches or exceeds the set threshold, a second temperature information value is generated. The control system controls the air blowing mechanism to continue operating while also controlling the heat dissipation enhancement mechanism to operate. With the help of the heat dissipation enhancement mechanism, the air blowing mechanism is assisted to take away the heat from the surface of the heat exchange tube 7, which is beneficial to speed up the cooling speed of the argon gas so that it can be reduced to a safe temperature range, thereby avoiding subsequent equipment damage or aging due to the temperature increase caused by compression.
