[0002] The gas phase material at the top of the rectifying tower is transported to the inside of the shell of the shell-and-tube heat exchanger in the steam generator through a pipeline, the gas phase material flows in the shell side of the shell-and-tube heat exchanger, and the hot water flows in the tube side of the heat exchanger, the tube wall serves as a partition wall, heat is transferred from the gas phase material to the tube wall, and then the heat is transferred from the tube wall to the hot water in the tube, the hot water heat exchange generates steam, which can provide steam for the heat tracing pipeline, heat energy recycling is realized, and energy waste is reduced.

[0003] Since the gas phase material is in the form of high-temperature steam, the hot water pipeline near the steam inlet of the shell will absorb a large amount of steam heat during the transportation of the gas phase material in the inside of the shell, however, the hot water pipeline at the rear position can only absorb residual heat, thereby causing uneven heat exchange, the hot water pipeline near the steam inlet will have the phenomenon of excess heat energy, the overall heat exchange efficiency is reduced, and the local overheating or subcooling phenomenon affects the stability of the equipment and shortens the service life of the heat exchange pipeline of the equipment.

[0004] Therefore, the utility model provides a steam generator to solve the above problems. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a steam generator to solve the problem of uneven heat absorption of the hot water pipeline, excess heat energy, and reduced heat exchange efficiency as mentioned in the background.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented by the following technical scheme: a steam generator, comprising a bottom plate and a shell, two fixed plates are fixedly installed at the top of the bottom plate, the shell penetrates between the two fixed plates, rotating discs penetrate the two sides of the shell, first heat exchange pipes penetrate between the centers of the two sides of the rotating discs away from each other, conveying pipes are communicated at the two ends of the first heat exchange pipes, inner gear rings are fixedly installed at the two sides of the shell and outside the rotating discs, a plurality of connecting pipes are uniformly communicated around the first heat exchange pipes at the opposite ends of the two conveying pipes, a plurality of second heat exchange pipes are uniformly penetrated around the first heat exchange pipes between the two sides of the rotating discs away from each other and inside the inner gear rings, transmission gears are sleeved with the outside of each second heat exchange pipe and inside the inner gear ring, and the two ends of the second heat exchange pipes extend to the opposite ends of the two connecting pipes respectively.

[0007] Further, the connecting pipes installed at the opposite ends of the two conveying pipes are mirror-symmetric, and the two ends of the second heat exchange pipes are rotationally connected with the two connecting pipes through rotary joints.

[0008] Furthermore, the transmission gear meshes with the internal gear ring, and the transmission gear is fixedly connected to the second heat exchange tube.

[0009] Furthermore, both turntables are rotatably connected to the housing via bearings, and the diameter of the turntables is smaller than the inner diameter of the internal gear ring.

[0010] Furthermore, the top of the housing is connected to a gaseous material input pipe, and the bottom of the housing is connected to a gaseous material output pipe.

[0011] Furthermore, a rotary joint is installed at the opposite ends of the two conveying pipes. A drive mechanism is installed on the outside of one of the conveying pipes and on one side of a fixed plate. The drive mechanism includes a support plate and an external gear ring. The support plate is fixedly installed on the top of one side of the fixed plate. Two support rods are fixedly installed between the bottom side of the support plate and the top side of the base plate. The external gear ring is sleeved on the outside of one of the conveying pipes. A motor is fixedly installed on the bottom of the support plate via a base. A drive shaft is fixedly installed on the output end of the motor.

[0013] The beneficial effects of this utility model are:

[0014] By activating the drive mechanism, the hot water pipe group consisting of two conveying pipes, multiple connecting pipes, a first heat exchange pipe, and multiple second heat exchange pipes is rotated as a whole. This allows multiple second heat exchange pipes to pass through the bottom of the gas phase material input pipe in turn, thereby ensuring that each second heat exchange pipe is heated uniformly by steam. This avoids the phenomenon of local heat exchange pipes being too hot or having excess heat energy, effectively improving the heat exchange efficiency and heat energy utilization rate of the steam generator.

[0015] While the turntable drives multiple second heat exchange tubes to rotate, the transmission gears fixedly fitted on each second heat exchange tube mesh with the internal gear ring, allowing the second heat exchange tubes to rotate on their own axis as the turntable revolves around the first heat exchange tube inside the shell. This ensures uniform heat exchange within the shell. Simultaneously, the rotation of the second heat exchange tubes ensures uniform contact between the heated tube wall and the hot water transported inside the pipe, preventing localized overheating and achieving uniform heat absorption in the heat exchange pipes. This extends the service life of the internal pipes of the steam generator. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-5This utility model provides a technical solution: a steam generator, including a base plate 1 and a shell 3. Two fixing plates 2 are fixedly installed on the top of the base plate 1. The shell 3 passes through the two fixing plates 2. Turntables 4 pass through both sides of the shell 3. A first heat exchange tube 6 passes through the center of the two turntables 4 on opposite sides. Both ends of the first heat exchange tube 6 are connected to conveying pipes 7. Internal gear rings 5 ​​are fixedly installed on both sides of the shell 3 and outside the turntables 4. Multiple connecting pipes 8 are evenly connected around the first heat exchange tube 6 at opposite ends of the two conveying pipes 7. Multiple second heat exchange tubes 10 are evenly distributed around the first heat exchange tube 6 inside the internal gear ring 5. Each second heat exchange tube 10 is rotatably connected to two turntables 4 via bearings. A transmission gear 11 is fitted onto the outside of each second heat exchange tube 10 and inside the internal gear ring 5. Both ends of the second heat exchange tube 10 extend to opposite ends of two connecting pipes 8. The connecting pipes 8 installed at opposite ends of the two conveying pipes 7 are mirror-symmetrical. Both ends of the second heat exchange tube 10 are rotatably connected to the two connecting pipes 8 via rotary joints. Each second heat exchange tube 10 is connected to the connecting pipes 8 rotatably connected at both ends. Each of the disjointed ends of the conveying pipe 7 is connected to an external pipeline via a rotary joint, allowing for rotatable connection between the conveying pipe 7 and the external pipeline. One conveying pipe 7 can deliver hot water to the interior of multiple connecting pipes 8, while another conveying pipe 7 can discharge steam generated from heating the hot water and excess hot water. The rotary joint is a mechanical sealing device used to achieve connection, conveying, and rotation between pipes. During operation, the rotary joint, through the coordinated action of components such as the outer shell, seals, bearings, clamps, and guide sleeves, achieves connection, conveying, and rotation between pipes. When the pipeline needs... During connection, the two pipes are first fixed with clamps. The rotary joint housing fits tightly with the clamps. The internal seal is located between the bearing and the housing, which plays a sealing role to prevent liquid or gas leakage. The guide sleeve is on the outside of the seal to guide the pipe to maintain the correct position during rotation and prevent deviation from the track. The bearing plays a supporting and transmission role, ensuring that the seal and the housing fit tightly to achieve a stable connection. The transmission gear 11 meshes with the internal gear ring 5 and is fixedly connected to the second heat exchange tube 10. Both turntables 4 are rotatably connected to the housing 3 through bearings. The diameter of the turntable 4 is smaller than the inner diameter of the internal gear ring 5.

[0025] Please see Figures 2-4 The top of the shell 3 is connected to a gas phase material input pipe 12, and the bottom of the shell 3 is connected to a gas phase material output pipe 13. The inlet of the gas phase material input pipe 12 is connected to the outlet pipe of the external distillation column, so that excess gas phase material inside the external distillation column can be transported from the gas phase material input pipe 12 to the inside of the shell 3. The outlet of the gas phase material output pipe 13 is connected to an external pipeline, so that the gas and condensate inside the shell 3 can be discharged to the external pipeline through the gas phase material output pipe 13.

[0026] Please see Figure 2 and Figure 5 Two conveying pipes 7 are each equipped with a rotary joint at one of their separated ends. A drive mechanism 9 is installed on the outside of one of the conveying pipes 7 and on one side of a fixed plate 2. The drive mechanism 9 includes a support plate 91 and an external gear ring 96. The support plate 91 is fixedly installed on the top of one side of a fixed plate 2. Two support rods 92 are fixedly installed between the bottom side of the support plate 91 and the top side of the base plate 1. The external gear ring 96 is sleeved on the outside of one of the conveying pipes 7. A motor 93 is fixedly installed on the bottom of the support plate 91 via a base. The motor 93 is connected to an external power supply and is equipped with a power control switch. A drive shaft 94 is fixedly installed on the output end of the motor 93. A drive wheel 95 is sleeved on the outside of the drive shaft 94 and on top of the external gear ring 96. The external gear ring 96 meshes with the drive wheel 95. The external gear ring 96 is fixedly connected to one of the conveying pipes 7, and the drive wheel 95 is fixedly connected to the drive shaft 94.

[0027] Specific implementation method: By starting a conveying pipe 7, hot water is evenly conveyed from multiple connecting pipes 8 to the interior of the first heat exchange pipe 6 and multiple second heat exchange pipes 10. The hot water is then conveyed through the first heat exchange pipe 6 and multiple second heat exchange pipes 10 to the interior of multiple connecting pipes 8 on another conveying pipe 7. At the same time, the gas phase material input pipe 12 conveys the gas phase material inside the distillation column to the interior of the shell 3. The gas phase material is in the form of high-temperature steam. While the high-temperature steam flows inside the shell 3, the hot water flows inside the first heat exchange pipe 6 and each of the second heat exchange pipes 10. The pipe wall acts as a partition, and heat is transferred from the gas phase material to the pipe wall, and then from the pipe wall to the hot water inside the pipe. This heats the hot water inside the first heat exchange pipe 6 and the second heat exchange pipe 10. The heated hot water generates steam, which is discharged from the other conveying pipe 7 along with the remaining hot water. The generated steam can be conveyed to an external heat tracing pipe for secondary steam heat energy utilization.

[0028] Simultaneously, the motor 93 inside the drive mechanism 9 is started, driving the drive shaft 94 to rotate. The drive shaft 94 drives the drive wheel 95 to rotate, and the drive wheel 95 drives the external gear ring 96 to rotate, thereby driving one conveying pipe 7 to rotate. Since both turntables 4 are rotatably connected to the housing 3 through bearings, when one conveying pipe 7 rotates, the hot water pipe group consisting of the two conveying pipes 7, multiple connecting pipes 8, the first heat exchange pipe 6, and multiple second heat exchange pipes 10 rotates as a whole. This allows multiple second heat exchange pipes 10 to pass through the bottom of the gas phase material input pipe 12 in turn, thereby ensuring that each second heat exchange pipe 10 is uniformly heated by steam, avoiding the phenomenon of local heat exchange pipe temperature being too high and excess heat energy, and effectively improving the heat exchange efficiency and heat energy utilization rate of the steam generator.

[0029] As the turntable 4 drives multiple second heat exchange tubes 10 to rotate, the transmission gears 11 fixedly fitted on each second heat exchange tube 10 mesh with the internal gear ring 5, allowing the second heat exchange tube 10 to rotate on its own axis while the turntable 4 revolves around the first heat exchange tube 6 inside the shell 3. This ensures uniform heat exchange within the shell 3. Simultaneously, the rotation of the second heat exchange tube 10 allows for uniform contact between the heated tube wall and the hot water transported inside the pipe, preventing localized overheating of the heat exchange tube and achieving uniform heat absorption in the heat exchange pipe, thus extending the service life of the internal pipes of the steam generator.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
