Description

Technical Field

[0001] This invention relates to the technical field of condensers, and more specifically to steam condensers. Background Technology

[0002] A steam condenser is a heat exchange device that cools gaseous steam and converts it into liquid through a cooling medium. It is mainly used for steam recovery, condensation and heat removal, and is mainly applied in industries such as chemical, pharmaceutical and food.

[0003] Patent document CN222783956U discloses a steam condenser arranged above a steam pool. The condenser includes a condensing cylinder, a cover plate at the top of the steam pool with a through hole in the center, a water inlet assembly at the center of the top of the condensing cylinder, and an air inlet at the bottom connected to the through hole in the cover plate. Air outlet pipes are evenly arranged circumferentially along the top of the sidewall of the condensing cylinder. Multiple layers of grates are evenly arranged from top to bottom within the condensing cylinder's inner cavity, each grate having a number of evenly spaced circular holes. A number of limiting devices corresponding to each grate are evenly arranged circumferentially from top to bottom along the sidewall of the condensing cylinder's inner cavity. The locking block has one side attached to the inner wall of the condenser cylinder and the other side has a locking groove. The outer wall of the grate is locked in the locking groove. The water inlet assembly includes a top plate, a main water inlet pipe and several water inlet pipes. The top plate is located on the top of the inner wall of the condenser cylinder with evenly distributed protrusions. The center of the top plate has a water pipe installation hole. The bottom end of the main water inlet pipe passes through the water pipe installation hole and extends into the inner cavity of the condenser cylinder. Several water inlet pipes are evenly distributed at the bottom end of the main water inlet pipe and are connected to the main water inlet pipe. Several spray nozzles are evenly distributed on the water inlet pipes. The waste steam generated by the production of autoclaved aerated concrete enters the inner cavity of the condenser cylinder from the steam water pool through the through hole. The waste steam is condensed in the process of flowing through the multi-layer grate.

[0004] However, this solution has the following problems: when the steam contains crystallizable components such as inorganic salts, organic acids, and easily sublimable solids, these components will enter the condensation equipment along with the steam. During condensation, the steam gradually undergoes a phase change and liquefaction. The crystallizable components, due to decreased solubility or increased concentration, precipitate from the condensate in crystal form. These precipitated crystals have strong adhesion and easily adhere to and deposit on the inner wall of the condenser and the heat exchange surface. Under continuous condensation and continuous material flow, the initially deposited tiny crystals act as nuclei, continuously adsorbing and encapsulating newly formed crystals, causing the crystalline layer to continuously thicken, accumulate, and compact, gradually forming agglomerates and eventually developing into a dense, hard crystalline scale. This crystalline scale forms a stable insulating layer on the heat exchange surface, significantly reducing the heat transfer coefficient and heat exchange efficiency. Summary of the Invention

[0005] This invention provides a steam condenser designed to solve the problem in related technologies where crystallizable components easily crystallize and form scale inside the condenser, leading to a decrease in heat exchange efficiency.

[0006] The steam condenser of the present invention includes a condensing tank, which contains a condensing cylinder, an intermediate cylinder, a control component, and a scraper. The condensing cylinder and the inner wall of the condensing tank together form a chamber for the flow of coolant. The intermediate cylinder is rotatably mounted inside the condensing cylinder, forming a channel for the flow of steam between them. The control component is connected to the intermediate cylinder and is used to drive the intermediate cylinder to rotate and simultaneously drive the intermediate cylinder to reciprocate in a direction perpendicular to its axis. One side of the scraper is rotatably engaged with the outer wall of the intermediate cylinder, and the other side abuts against the side wall of the condensing cylinder. A torsion spring is provided at the connection between the scraper and the intermediate cylinder to keep the scraper abutting against the condensing cylinder. The side of the scraper near the condensing cylinder is inclined along the rotation direction of the intermediate cylinder. A discharge port is provided below the intermediate cylinder at a position corresponding to the scraper. The scraper scrapes away crystals from the inner wall of the condensing cylinder as the intermediate cylinder rotates, and the intermediate cylinder reciprocates synchronously to crush the crystals. The crushed crystals are discharged from the discharge port.

[0007] By setting up an intermediate cylinder, control components, and scrapers, the intermediate cylinder is driven to rotate by the control components and reciprocate along the vertical axis. In conjunction with the scrapers, which are always in contact with the inner wall of the condenser cylinder, the precipitated crystals are scraped off and broken up. Specifically, during steam condensation, the control components are activated synchronously, driving the intermediate cylinder to rotate at a constant speed around its own axis. Simultaneously, the intermediate cylinder moves back and forth in a direction perpendicular to its own axis, forming a combined rotational and reciprocating motion. The scraper is mounted on the outer wall of the intermediate cylinder via a rotating shaft. A torsion spring at the connection point continuously applies elastic preload. Combined with the structure where the scraper is tilted along the rotation direction of the intermediate cylinder, the other side of the scraper is always in close contact with the inner wall of the condenser cylinder, continuously scraping away the crystalline layer attached to the inner wall of the condenser cylinder. This prevents the crystallization from thickening and forming scale, which can obstruct heat exchange. The synchronous reciprocating movement of the intermediate cylinder causes the gap between it and the condenser cylinder to periodically narrow and widen. When the gap narrows, it forcefully squeezes and breaks up the accumulated crystal clumps. When the gap widens, the broken crystal particles settle downwards under gravity. The discharge port at the bottom of the intermediate cylinder, corresponding to the scraper, allows the crystals to settle smoothly and be discharged through the channel. This process achieves simultaneous condensation and crystallization, scraping and peeling, and crushing to prevent scaling and continuously ensure condensation heat exchange efficiency.

[0008] Preferably, the control assembly includes a drive component, a push component, a control rod, and a connecting plate. The control rod is rotatably mounted inside the condenser. The output end of the drive component is connected to the control rod to drive its rotation. The connecting plate is located inside the intermediate cylinder and connected to the intermediate cylinder. The push component is located at the lower end of the control rod, and its output end is connected to the connecting plate.

[0009] The driving component outputs rotational power, driving the control rod to rotate circumferentially. During rotation, the control rod, through its cooperating transmission structure, forms a linkage with the connecting plate, thereby driving the intermediate cylinder to rotate around the control rod as the center. Simultaneously, the pushing component applies a directional force to the connecting plate, causing the connecting plate to rotate with the control rod while also generating lateral displacement. This results in the intermediate cylinder not only rotating around the control rod but also displacing laterally, achieving a combined motion of rotation and lateral movement. During this combined motion, the intermediate cylinder drives the scraper on it to continuously scrape away the crystalline material. During the scraping process, the relative motion and squeezing action between the scraper and the material break down the scraped crystals.

[0010] Preferably, the pushing component includes a mounting frame, a cylinder, a slider, and a connecting rod. The mounting frame is fixedly connected to the lower end of the control rod. The slider is slidably assembled in the mounting frame in a direction perpendicular to the axis of the control rod. The connecting rod is connected to the slider and the connecting plate respectively. The cylinder is mounted on the mounting frame, and its output end is connected to the slider to drive the slider to move.

[0011] The cylinder serves as the power source, with its output end fixedly connected to the slider. The slider is slidably mounted inside the mounting frame. Driven by the cylinder, the slider can perform stable reciprocating linear motion along the guide direction of the mounting frame. A connecting rod is fixedly mounted on the slider, moving synchronously with it and transmitting power to the connecting plate, ensuring synchronized movement of the connecting plate, slider, and connecting rod. The connecting plate is fixedly connected to the intermediate cylinder, directly driving the intermediate cylinder to move together during its movement, ultimately achieving stable and synchronized reciprocating movement of the intermediate cylinder in the lateral direction.

[0012] Preferably, the control rod has an airflow channel inside and an opening at the upper end. A steam inlet pipe is provided on the condenser, which is sleeved on the outside of the control rod. The control rod and the steam inlet pipe are rotatably connected. A steam inlet plate communicating with the airflow channel is provided on the side of the control rod. The end of the steam inlet plate away from the control rod passes through the intermediate cylinder and extends to the space between the intermediate cylinder and the condenser cylinder.

[0013] Steam first enters the internal cavity of the control rod via the steam inlet pipe. The control rod has dedicated airflow channels along its axial or radial direction. Under pressure, the steam flows stably along these channels and then enters the steam inlet plate connected to the control rod. The steam inlet plate distributes and guides the steam, ensuring it enters the annular condensation chamber formed by the intermediate cylinder and the condenser cylinder evenly and smoothly. This creates conditions for sufficient contact between the steam and the condenser wall, achieving condensation and heat exchange. Simultaneously, the control rod and the steam inlet pipe employ a rotating fit structure, allowing relative rotational movement without causing jamming, collision, or interference with the control rod's rotation. This ensures continuous steam delivery and smooth control rod operation.

[0014] Preferably, the steam inlet plate and the intermediate cylinder are in sliding fit, and the sliding direction of the steam inlet plate is the same as the sliding direction of the slider.

[0015] The steam inlet plate and the intermediate cylinder are assembled using a sliding fit, with both sliding in the same direction and moving relatively linearly along the same axis. During the lateral movement of the intermediate cylinder, the steam inlet plate remains fixed relative to the control rod and does not move synchronously with the intermediate cylinder. Under this motion relationship, the steam inlet plate can slide relative to the intermediate cylinder in a preset direction. Because the sliding direction is consistent and the steam inlet plate and control rod remain relatively fixed, the intermediate cylinder will not interfere with the steam inlet plate during lateral movement, causing jamming or uneven wear. This achieves both the relative motion function between the two and ensures stable steam flow through the steam inlet plate.

[0016] Preferably, a baffle plate is provided below the intermediate cylinder, and the baffle plate slides against the lower part of the condenser cylinder, with the discharge port opened on the baffle plate; when the intermediate cylinder moves back and forth along the vertical axis, the baffle plate and the condenser cylinder always remain in contact.

[0017] As the intermediate cylinder reciprocates along its own axis, the baffle moves synchronously with it and maintains a continuous, close contact with the lower part of the condenser cylinder, without any separation gap. By forming a tight seal between the lower parts of the intermediate cylinder and the condenser cylinder through the baffle, the mating gap between them is effectively sealed, preventing material or gas leakage and ensuring the sealing reliability of the structure during relative sliding.

[0018] Preferably, an elastic telescopic plate is provided on the outer side of the intermediate cylinder, the elastic telescopic plate abuts against the inner wall of the condenser cylinder, the elastic telescopic plate and the scraper are spaced apart, and the elastic telescopic plate and the steam inlet plate are arranged sequentially in the direction away from the rotation of the intermediate cylinder.

[0019] When the intermediate cylinder rotates under the drive, the scraper first performs the main scraping of the crystals attached to the inner wall of the condenser cylinder. The elastic telescopic plate that follows then uses its own elastic telescopic properties to always keep close to the inner wall of the condenser cylinder, and performs secondary auxiliary scraping of the small amount of fine crystals and thin crystal layers left after the scraper. Through the synergistic effect of the main scraping of the scraper and the auxiliary cleaning of the elastic telescopic plate, the phenomenon of residual crystals attached to the inner wall is effectively eliminated, and the overall scraping effect of crystals on the inner wall of the condenser cylinder is greatly improved.

[0020] Preferably, the discharge port is arranged in an arc around the axis of the intermediate cylinder, and the discharge port is located below the scraper and the elastic telescopic plate.

[0021] The discharge ports correspond to the positions of the scraper and the elastic telescopic plate, ensuring that the crystals scraped off by the scraper and the crystals scraped and peeled off by the elastic telescopic plate can fall directly into the corresponding discharge ports under the action of gravity, achieving precise correspondence between scraping and discharge, so that all scraped crystals can be smoothly and without retention discharged out through the discharge ports.

[0022] Preferably, a top plate is provided on the outer side of the intermediate cylinder, and multiple top plates are arranged in a vertical direction. The top plates are located between the scraper and the intermediate cylinder. When the scraper rotates, it cooperates with the top plate to break the crystal.

[0023] By setting a top plate, when the scraper rotates and approaches the top plate, the two work together to break up the agglomerated crystals, thus improving the crystal breaking effect.

[0024] Preferably, the drive unit includes a motor and a bevel gear set. The drive unit is fixedly installed inside the condenser tank, and the output shaft of the drive unit is connected to the control lever via the bevel gear set.

[0025] The motor drives the control lever to rotate via a bevel gear set, thereby achieving the rotation adjustment of the intermediate cylinder.

[0026] Beneficial effects: This invention achieves efficient heat exchange and crystallization of steam, continuous scraping and fine crushing of crystalline materials, avoidance of scale buildup and blockage on the inner wall of the condenser, and long-term stable maintenance of high heat exchange efficiency by setting up an intermediate cylinder with combined rotational and horizontal reciprocating motion, scrapers and elastic telescopic plates that fit against the inner wall of the condenser, and a compression and shearing structure with the top plate.

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figures 1 to 7 As shown, the steam condenser of the present invention includes a condenser tank 1, and a condenser cylinder 11, an intermediate cylinder 2, a control component 3, and a scraper 4 are arranged inside the condenser tank 1. The condenser cylinder 11 and the inner wall of the condenser tank 1 cooperate with each other to form a closed chamber for the flow of coolant. An inlet and an outlet communicating with the closed chamber are provided on the side of the condenser tank 1. Coolant can be introduced into the chamber through the inlet and then discharged through the outlet to achieve circulation. The condensation and heat exchange of the internal steam is achieved by the circulation of coolant in the chamber. The intermediate cylinder 2 is rotatably assembled inside the condenser cylinder 11. The outer wall of the intermediate cylinder 2 is spaced apart from the inner wall of the condenser cylinder 11, that is, the outer diameter of the intermediate cylinder 2 is smaller than the inner diameter of the condenser cylinder 11. An annular channel for the flow of steam to be condensed is formed between the two. The steam exchanges heat with the wall of the condenser cylinder 11 in the channel and crystals are precipitated.

[0037] The control component 3 is connected to the intermediate cylinder 2, which can not only drive the intermediate cylinder 2 to rotate around its own axis, but also drive the intermediate cylinder 2 to reciprocate in a direction perpendicular to its axis, realizing a compound motion output. One side of the scraper 4 forms a rotational engagement with the outer wall of the intermediate cylinder 2, while the other side always abuts against the inner wall of the condenser cylinder 11. A torsion spring (not shown in the figure) is provided at the connection position between the scraper 4 and the intermediate cylinder 2. The elastic force of the torsion spring ensures that the scraper 4 and the inner wall of the condenser cylinder 11 remain stably abutted. At the same time, the side of the scraper 4 closest to the condenser cylinder 11 is inclined along the rotation direction of the intermediate cylinder 2 to improve the scraping effect and smoothness. A discharge port 5 is provided at the position corresponding to the scraper 4 below the intermediate cylinder 2.

[0038] During operation, coolant is first introduced into the condenser cylinder 11 to form a stable low-temperature heat exchange surface on the inner wall of the condenser cylinder 11. Then, the steam to be treated is introduced into the cavity between the intermediate cylinder 2 and the condenser cylinder 11. During the flow, the steam comes into full contact with the low-temperature inner wall of the condenser cylinder 11, resulting in heat exchange and condensation. The solute in the steam crystallizes and adheres to the inner wall of the condenser cylinder 11. During this process, the control component 3 drives the intermediate cylinder 2 and the scraper 4 to rotate synchronously. The scraper 4, closely attached to the inner wall of the condenser cylinder 11, rotates with the intermediate cylinder 2, continuously scraping off the crystallized material from the inner wall of the condenser cylinder 11. The intermediate cylinder 2 rotates simultaneously... It also reciprocates perpendicular to its own axis of rotation, causing the annular gap between the intermediate cylinder 2 and the condenser cylinder 11 to change periodically. When the intermediate cylinder 2 moves to a position where the gap between it and the condenser cylinder 11 decreases, it can squeeze and crush the scraped crystal material, refining the agglomerated or larger crystal particles. Finally, the crushed crystal material is discharged from the corresponding discharge port 5 at the bottom of the equipment under the action of gravity and structural guidance, thereby effectively avoiding the crystal from adhering to the inner wall of the condenser cylinder 11 for a long time and causing scaling and blockage, ensuring that the heat exchange surface works continuously and efficiently, and significantly improving the overall heat exchange efficiency.

[0039] The scraper 4 and the intermediate cylinder 2 are connected by a rotating fit, allowing the scraper 4 to rotate freely relative to the intermediate cylinder 2 around its own axis. When the intermediate cylinder 2 reciprocates axially, the scraper 4 can adaptively rotate according to the motion resistance and contact state to conform to the movement of the condenser cylinder 11 and avoid jamming or scraping interference. In addition, a torsion spring is provided between the scraper 4 and the intermediate cylinder 2. Under the preload torque of the torsion spring, the working edge of the scraper 4 always elastically abuts against the inner wall surface of the condenser cylinder 11, ensuring a stable and continuous contact pressure between the scraper 4 and the inner wall of the condenser cylinder 11.

[0040] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 The control component 3 includes a drive element 31, a pusher element 32, a control rod 33, and a connecting plate 34. The control rod 33 is rotatably mounted in the internal cavity of the condenser tank 1. The output end of the drive element 31 is directly connected to the control rod 33, providing a stable and controllable rotational driving force for the control rod 33. The connecting plate 34 is arranged in the internal cavity of the intermediate cylinder 2 and forms a fixed connection structure with the intermediate cylinder 2, allowing the two to move synchronously. The pusher element 32 is installed at the lower end of the control rod 33 and rotates synchronously with the control rod 33. Its output end is connected to the connecting plate 34, which can both transmit rotational torque and drive the connecting plate 34 to move relative to the control rod 33.

[0041] During normal operation of the condensation equipment, the drive unit 31 starts and outputs rotational power, directly driving the control rod 33 to rotate around its own axis. While rotating, the control rod 33 transmits power to the lower pusher 32, causing the pusher 32 to rotate synchronously with the control rod 33. The pusher 32 transmits rotational torque to the connecting plate 34 through its output end, which then drives the intermediate cylinder 2, which is fixed to it, to rotate together, achieving circumferential adjustment of the intermediate cylinder 2. Simultaneously, the pusher 32 drives the connecting plate 34 and the intermediate cylinder 2 to reciprocate linearly in a direction perpendicular to the axis of the control rod 33, giving the intermediate cylinder 2 a combined motion state of rotation and reciprocating movement.

[0042] Reference Figure 1 , Figure 5 , Figure 7 The driving component 31 includes a motor 311 and a bevel gear set 312. The motor 311 serves as a power source, with its output end connected to the driving end of the bevel gear set 312. The driven end of the bevel gear set 312 forms a transmission engagement with the control lever 33. The power output by the motor 311 is transmitted through the bevel gear set 312. Through the meshing transmission of the bevel gear set 312, the rotational motion is smoothly transmitted to the control lever 33, thereby driving the control lever 33 to move in a preset manner, thus realizing the rotational motion of the control lever 33 and the intermediate cylinder 2.

[0043] Reference Figure 1 , Figure 5 , Figure 6 , Figure 7 The pusher 32 includes a mounting frame 321, a cylinder 322, a slider 323, and a connecting rod 324. The mounting frame 321 is fixedly connected to the lower end of the control rod 33. The slider 323 is slidably mounted inside the mounting frame 321, and its sliding direction is perpendicular to the central axis of the control rod 33. The two ends of the connecting rod 324 are respectively connected to the slider 323 and the connecting plate 34. The cylinder 322 is fixedly mounted on the mounting frame 321, and its output end is connected to the slider 323 and used to drive the slider 323 to slide in the aforementioned direction.

[0044] When the control lever 33 rotates, the mounting frame 321, slider 323 and connecting rod 324 will rotate synchronously with the control lever 33. During this process, the cylinder 322 can drive the slider 323 to make reciprocating linear motion within the mounting frame 321. During the movement, the slider 323 drives the connecting plate 34 to move back and forth synchronously through the connecting rod 324, thereby driving the intermediate cylinder 2 to move back and forth along the set direction while rotating with the control lever 33.

[0045] Reference Figure 1 , Figure 5 , Figure 6 , Figure 7To facilitate the introduction of steam into the intermediate cylinder 2 and the condenser cylinder 11, a through-flow channel 331 is provided axially inside the control rod 33. The upper end of the control rod 33 has an opening communicating with the airflow channel 331. A steam inlet pipe 12 is fixedly installed on the condenser cylinder 1, located at the upper end of the condenser cylinder 1. The steam inlet pipe 12 is coaxially sleeved on the upper outer side of the control rod 33. The inner wall of the steam inlet pipe 12 and the upper outer wall of the control rod 33 form a rotational fit relationship, employing a rotational sealing structure to achieve relative rotation while ensuring a sealing effect. A steam inlet plate 6 is fixedly installed on the side of the control rod 33. The interior of the steam inlet plate 6 communicates with the airflow channel 331 inside the control rod 33, allowing steam to enter the interior of the steam inlet plate 6 through the airflow channel 331. The end of the steam inlet plate 6 furthest from the control rod 33 extends radially outward, passing through a corresponding through hole on the intermediate cylinder 2 and extending between the intermediate cylinder 2 and the condenser cylinder 11.

[0046] During operation, external steam enters through the steam inlet pipe 12, flows into the airflow channel 331 inside the control rod 33 through the opening at the upper end of the control rod 33, and is then guided by the steam inlet plate 6 into the cavity between the intermediate cylinder 2 and the condenser cylinder 11. When the intermediate cylinder 2 rotates around its axis, the control rod 33 rotates synchronously through the steam inlet plate 6. The control rod 33 and the steam inlet pipe 12 maintain relative rotation and remain sealed, effectively preventing steam leakage from the mating gap. This ensures that steam can stably and continuously enter the space between the intermediate cylinder 2 and the condenser cylinder 11, providing a stable steam source for condensation heat exchange.

[0047] Reference Figure 2 , Figure 3 , Figure 5 The steam inlet plate 6 and the intermediate cylinder 2 are assembled by a sliding fit, forming a movable connection structure that can slide relative to each other; at the same time, the sliding direction of the steam inlet plate 6 is designed to be consistent with the sliding direction of the slider 323.

[0048] By sliding the steam inlet plate 6 with the intermediate cylinder 2, the steam inlet plate 6 can rotate synchronously with the intermediate cylinder 2 and slide relative to the intermediate cylinder 2, thereby avoiding problems such as motion interference, jamming or collision between the steam inlet plate 6 and the intermediate cylinder 2.

[0049] Furthermore, after the end of the steam inlet plate 6 passes through the corresponding mounting hole or mating section of the intermediate cylinder 2, it continues to extend outward along the direction of movement for an effective length, forming sufficient axial overlap allowance and guide stroke. This extension structure ensures that the steam inlet plate 6 maintains an effective mating state with the intermediate cylinder 2 throughout its entire stroke, preventing separation, mating failure, or guide deviation due to excessive displacement, thereby ensuring the continuity and stability of the sliding fit between the steam inlet plate 6 and the intermediate cylinder 2.

[0050] Reference Figure 1 , Figure 4 ,Figure 5 A baffle plate 7 is fixedly installed below the intermediate cylinder 2. The baffle plate 7 has an overall annular plate structure, and its outer diameter is larger than the inner diameter of the condenser cylinder 11, so that it can cover the lower end of the condenser cylinder 11. The baffle plate 7 and the lower end face of the condenser cylinder 11 form a sliding abutment fit, which can completely block and seal the lower connection area between the intermediate cylinder 2 and the condenser cylinder 11; the discharge port 5 is opened on the baffle plate 7 for material discharge.

[0051] When the intermediate cylinder 2 reciprocates along its own axis under the driving action, the baffle plate 7 reciprocates synchronously with the intermediate cylinder 2. During the sliding process, the baffle plate 7 and the lower end face of the condenser cylinder 11 always remain in close contact, so that the lower fitting gap between the intermediate cylinder 2 and the condenser cylinder 11 is always sealed by the baffle plate 7, thereby effectively preventing the steam inside the condenser cylinder 11 from leaking out from the lower gap and ensuring the stability of the condensation operation.

[0052] Reference Figure 2 , Figure 3 , Figure 4 An elastic telescopic plate 8 is provided on the outer wall of the intermediate cylinder 2. The elastic telescopic plate 8 extends radially outward, and its outer edge maintains elastic contact with the inner wall of the condenser cylinder 11, allowing it to slide along the inner wall of the condenser cylinder 11 as the intermediate cylinder 2 rotates. The elastic telescopic plate 8 and the scraper 4 are arranged at intervals in the circumferential direction, and are arranged sequentially along the rotation direction of the intermediate cylinder 2. That is, the scraper 4, the elastic telescopic plate 8, and the steam inlet plate 6 are arranged sequentially along the rotation direction of the intermediate cylinder 2. The scraper 4 and the steam inlet plate 6 are respectively adjacent to the two sides of the elastic telescopic plate 8, forming a structure that is distributed sequentially in the circumferential direction.

[0053] Reference Figure 2 , Figure 3 The discharge port 5 is arranged in an arc shape around the rotation axis of the intermediate cylinder 2, and the discharge port 5 is located in the area below the scraper 4 and the elastic telescopic plate 8, corresponding to the falling path of the scraped material.

[0054] When the intermediate cylinder 2 drives the scraper 4 to rotate, the scraper 4 first scrapes off the crystals condensed and precipitated on the inner wall of the condensing cylinder 11. Subsequently, the elastic telescopic plate 8 continues to rotate with the intermediate cylinder 2, and uses its elastic contact with the inner wall of the condensing cylinder 11 to perform a secondary auxiliary scraping of the residual crystals that the scraper 4 did not completely remove, further improving the thoroughness of crystal removal. The crystals scraped off by the scraper 4 and the elastic telescopic plate 8 fall under the action of gravity and can be smoothly discharged through the corresponding arc-shaped discharge ports 5 below them, avoiding the accumulation of crystals in the cylinder.

[0055] By placing the steam inlet plate 6 on the side of the elastic telescopic plate 8 away from and adjacent to the scraper plate 4, the scraper plate 4 and the steam inlet plate 6 in front of it can maintain a large circumferential distance, thereby providing sufficient heat exchange and crystallization time for the steam to enter the inner wall area of ​​the condenser cylinder 11, ensuring that the crystals can be fully and stably precipitated.

[0056] Furthermore, while rotating around its own axis, the intermediate cylinder 2 also reciprocates horizontally, causing the annular gap between the outer wall of the intermediate cylinder 2 and the inner wall of the condenser cylinder 11 to periodically expand and shrink. This periodic change in the gap continuously disturbs the steam between the two, disrupting the stable laminar flow state of the steam and making its distribution within the annular space more uniform. This effectively enhances the contact frequency and area between the steam and the inner wall of the condenser cylinder 11, strengthening the heat exchange effect and significantly improving the precipitation efficiency and uniformity of crystals on the inner wall of the condenser cylinder 11.

[0057] Reference Figure 4 A top plate 9 is fixedly installed on the outer wall of the intermediate cylinder 2. The top plates 9 are arranged at intervals along the vertical direction to form a multi-layer crushing structure, and the top plates 9 are all located in the area between the scraper 4 and the intermediate cylinder 2.

[0058] During its rotation, the scraper 4 works in conjunction with the top plate 9 to crush the crystalline material. As the scraper 4 rotates, it first scrapes off the crystals adhering to the outer wall of the intermediate cylinder 2. The scraped-off crystals move towards the discharge port 5 under the influence of gravity and are eventually discharged through the discharge port 5. For larger crystalline clumps, they are subjected to the squeezing action of the intermediate cylinder 2 during the material flow, thus achieving initial crushing and decomposition.

[0059] Furthermore, when the intermediate cylinder 2 moves laterally, the scraper 4 rotates synchronously. As the scraper 4 rotates and gradually approaches the top plate 9, a relative squeezing and shearing action is formed between the scraper 4 and the top plate 9, further crushing the crystalline material. Since the top plates 9 are arranged at intervals along the vertical direction, they can form multi-point and layered crushing of the crystalline material at different heights, greatly improving the crushing effect and uniformity. This allows for more efficient crushing of the crystalline material to the preset particle size, ensuring that the crushed crystals meet the discharge requirements and are smoothly discharged through the discharge port 5. This ensures that the entire crystal scraping and crushing discharge process is continuous, stable, and smooth.

[0060] The implementation principle of this invention is as follows: When the system is working, coolant is first introduced between the condenser cylinder 11 and the condenser tank 1, and steam to be treated is introduced between the intermediate cylinder 2 and the condenser cylinder 11. The motor 311 drives the control rod 33 to rotate through the bevel gear set 312. The control rod 33 drives the lower pusher 32 to rotate synchronously in the circumferential direction. The pusher 32 drives the intermediate cylinder 2 to rotate around its own axis through the connecting plate 34. At the same time, the cylinder 322 inside the pusher 32 drives the slider 323 to slide back and forth in the mounting frame 321. Then, through the connecting rod 324, the connecting plate 34 and the intermediate cylinder 2 move horizontally back and forth synchronously perpendicular to the axis of rotation, so that the intermediate cylinder 2 forms a compound motion of rotation and horizontal reciprocating motion.

[0061] The steam to be treated comes into contact with the inner wall of the low-temperature condenser 11 and undergoes heat exchange, causing the solute to crystallize and adhere to the cylinder wall. The scraper 4, rotating synchronously with the intermediate cylinder 2, remains in close contact with the inner wall of the condenser 11, continuously scraping away the crystals. The adjacent circumferential elastic telescopic plates 8 rotate synchronously, providing secondary auxiliary cleaning of residual crystals on the cylinder wall, improving the thoroughness of scraping. The horizontal reciprocating motion of the intermediate cylinder 2 causes the annular channel gap to periodically expand and contract, disturbing the steam and disrupting the laminar flow, enhancing heat exchange and improving crystallization uniformity. Simultaneously, it performs preliminary crushing of the scraped-off crystal clumps. During the rotation of the scraper 4, it forms a continuous squeezing and shearing action with the top plate 9, achieving multi-point, layered, and refined crushing of the crystal material. This effectively prevents scale buildup and blockage on the inner wall of the condenser 11, maintaining high heat exchange efficiency.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
