Description

Technical Field

[0001] This invention relates to the field of condensate recovery technology, and in particular to a condensate recovery and circulation device for a desuperheater / pressure reducer. Background Technology

[0002] In industrial production, desuperheaters and pressure reducers are widely used in the cooling and depressurization processes of steam systems, generating a large amount of high-temperature condensate during operation. To conserve water and heat energy, this condensate is typically recycled and reused. However, existing condensate recovery equipment still has significant shortcomings in practical applications.

[0003] First, condensate often contains solid impurities such as rust and pipe debris, which can easily cause blockages or wear in subsequent water-using equipment if directly recycled. Second, the high temperature of the condensate means that direct reuse without effective cooling can affect system stability and even pose safety hazards. Third, existing equipment often uses simple filtration or heat exchange methods, lacking multi-stage purification capabilities for condensate, making it difficult to simultaneously remove impurities, regulate temperature, and stabilize water quality, resulting in poor recycled water quality that fails to meet reuse requirements. Furthermore, during operation, the filtration and heat exchange components of existing equipment are prone to reduced efficiency due to impurity buildup, and the lack of an effective online cleaning mechanism leads to significant performance degradation over long-term operation, frequent maintenance, and high operating costs. Therefore, we propose a condensate recycling system for desuperheaters and pressure reducers. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0018] 1. This invention, through the heat-conducting pipes, filter blocks, and rotating frame set in the filtration assembly, can achieve the cutting, crushing, and fine filtration of large particles of impurities in the early stage of condensate entering the equipment. Combined with the initial heat exchange of the heat-conducting pipes and heat-conducting blocks, it achieves the synergistic treatment of impurity removal and temperature reduction. Then, the condensate is subjected to secondary enhanced heat exchange through the threaded heat exchange pipes in the heat exchange assembly, further reducing the water temperature. Finally, the auxiliary components add rust remover and flocculant to the reaction vessel, and with the help of stirring, mixing, and settling, the iron components and suspended solids in the water are effectively removed, forming a purification process that combines multi-stage filtration, heat exchange, and chemical treatment, ensuring that the recycled water meets the reuse standards.

[0019] 2. The filter assembly of the present invention is equipped with a rotating frame driven by a mating rod. When the rotating frame rotates, it can scrape off the impurities attached to the side of the filter block, and the impurities can be automatically discharged through the corresponding connection between the dirt guide groove and the mating groove, which effectively avoids the clogging of the filter holes. In addition, in the heat exchange assembly, when the constraint cylinder rotates with the mating rod, it can drive the scraper to clean the inner wall of the first tube. At the same time, the physical isolation of the coolant channel is achieved through the cooperation of the trigger rod and the mounting frame, preventing cross-contamination between coolant and condensate during the cleaning process.

[0020] 3. This invention utilizes the interaction between the electric push rod and the mating rod in the drive assembly, along with the engagement and disengagement of the first, second, and third mating blocks at different positions, to flexibly switch between multiple working modes such as filtration, heat exchange, cleaning, sealing, and mixing within the same device. For example, when the mating rod moves upward, it can drive the rotating plate and heat-conducting pipe to rotate as a whole to enhance the heat exchange effect; when the mating rod moves downward, it can drive the rotating frame and scraper to perform cleaning operations on the filtration and heat exchange components respectively. This makes the device compact, easy to control, and adaptable to the treatment needs under different water quality conditions.

[0021] 4. This invention integrates filtration, heat exchange, chemical treatment, and self-cleaning functions into the same reactor and tube structure. The components are linked and driven by the connecting rods, eliminating the need for multiple additional power sources. The overall structure is compact, occupies little space, and is easy to install and maintain. It is suitable for the matching and modification of various desuperheating and pressure reducing systems.

[0038] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0039] Example: Figures 1 to 4As shown, a condensate recovery and circulation device for a desuperheater / pressure reducer includes a reactor 1, which is a hollow cylindrical tank. A first tube 11, a second tube 12, and a third tube 13 are equidistantly arranged on the upper side of the reactor 1. The reactor 1, the first tube 11, the second tube 12, and the third tube 13 are fixedly installed by bolts. A pipe is provided on the upper side of the third tube 13 for condensate to enter. A drain pipe 14 is fixedly installed through the reactor 1 on the lower side, and a liquid drain pipe 15 is fixedly installed through the reactor 1 on the side. A drive assembly 2 and a filter are installed inside the reactor 1. The system comprises component 3, heat exchange component 4, and auxiliary component 5. Specifically, condensate enters the second tube 12, the first tube 11, and the interior of the reactor 1 through the third tube 13. First, the condensate is filtered for impurities and undergoes preliminary heat exchange and cooling through the filter component 3. Then, it undergoes further heat exchange and cooling through the heat exchange component 4. Finally, the auxiliary component 5 is used to add rust remover and flocculant mixture. The auxiliary component 5 can also shut off the reactor 1, allowing the treated condensate to settle. The treated water is then discharged through the drain pipe 15, and the impurities accumulated at the bottom of the reactor 1 are discharged through the drain pipe 14.

[0040] like Figures 4 to 6 As shown, the drive assembly 2 includes a motor 21, which is located at the lower center of the reactor 1 and is fixedly connected to the lower side of the reactor 1 via a bracket. A connecting rod 22 is fixedly installed at the output end of the motor 21, extending through the reactor 1 into its interior. Stirring rods 221 are fixedly installed at equal intervals on the side of the connecting rod 22, and the stirring rods 221 are attached to the inner bottom of the reactor 1. A power supply module 231 and an electric actuator 23 are fixedly installed inside the motor 21, and the electric actuator 23 and the power supply module 231 are electrically connected to each other. The output end of the electric actuator 23 extends to the upper side of the connecting rod 22. The power supply module 231 is charged... The port is located at the lowest position of the connecting rod 22, with the lowest side of the connecting rod 22 located on the outside of the reactor 1. The power supply module 231 is a rechargeable lithium battery. A mating rod 24 is fixedly installed at the output end of the electric push rod 23, and the mating rod 24 extends into the first tube 11, the second tube 12, and the third tube 13. Specifically, when the motor 21 drives the connecting rod 22 to rotate, the connecting rod 22 can drive the stirring rod 221 to scrape the bottom side of the reactor 1. The power supply module 231 directly supplies power to the electric push rod 23, allowing the electric push rod 23 to push and pull the mating rod 24 to move its position, thus triggering different operations of each component.

[0041] like Figure 3 , Figure 4 and Figures 6 to 9As shown, the filter assembly 3 includes a first rotating plate 31 and a second rotating plate 32. The first rotating plate 31 is rotatably mounted on the inner side of the junction of the second tube 12 and the third tube 13. The second rotating plate 32 is rotatably mounted on the inner side of the junction of the reactor 1 and the first tube 11 and the second tube 12. A heat-conducting pipe 33 is fixedly installed through the sides of the first rotating plate 31 and the second rotating plate 32 at equal intervals. The heat-conducting pipe 33 is a hollow circular tube made of heat-conducting material. A rod 24 is movably disposed inside the heat-conducting pipe 33 located at the center position. Various parts are fixedly sleeved on the sides of the heat-conducting pipe 33 at equal intervals. A heat-conducting block 34 is a circular block of heat-conducting material. A filter block 35 is fixedly installed inside the heat-conducting pipe 33 and is flush with the first rotating plate 31. The filter block 35 is a circular block with holes on its side. A rotating frame 36 is rotatably installed inside the third tube 13 and is positioned above the first rotating plate 31. The rotating frame 36 is a circular frame with an "L"-shaped cross-section and damping rubber strips on its side. A discharge groove 361 is provided on the side of the rotating frame 36 corresponding to the position of the heat-conducting pipe 33, and a filter block 35 is fixedly installed at equal intervals inside the discharge groove 361. The cutting plate 363 has a guide groove 362 equidistantly provided on the lower side of the rotating frame 36, corresponding to the discharge groove 361. The guide groove 362 is a T-shaped groove. A first mating block 37 is fixedly sleeved on the upper side of the mating rod 24 and is located inside the rotating frame 36. A through-groove mating groove 38 is provided on the inner side of the third tube 13, corresponding to the horizontal position of the first rotating plate 31. Specifically, after the condensate enters the third tube 13, it flows into the heat pipe 33 through the discharge groove 361. At the same time, the cutting plate 363 removes larger impurities in the condensate. The filter blocks 35 cut and crush the impurities in the condensate, which are then filtered through the heat-conducting pipes 33 and 34 to cool the condensate. Additionally, when the electric push rod 23 pulls the mating rod 24 downward, the first mating block 37 is elastically engaged with the side of the rotating frame 36. At this time, the rotation of the mating rod 24 can drive the rotating frame 36 to rotate inside the third tube 13. When the rotating frame 36 rotates, it scrapes the impurities on the side of the filter blocks 35. After passing through the corresponding positions of the guide groove 362 and the mating groove 38, the scraped impurities can be discharged through the guide groove 362 and the mating groove 38.

[0042] like Figure 3 , Figure 4 , Figure 6 and Figures 10 to 12As shown, the heat exchange assembly 4 includes a heat exchange tube 41, which is located inside the first tube 11. The heat exchange tube 41 is a hollow, threaded, heat-conducting round tube. A water inlet pipe 411 is fixedly installed through the side of the second tube 12 and is connected to an external coolant supply. A connecting pipe 412 is fixedly installed through the side of the first tube 11 and the second tube 12, corresponding to the inlet port of the heat exchange tube 41. An electrically controlled valve is provided on the side of the connecting pipe 412. A drain pipe 413 is provided, corresponding to the discharge port of the heat exchange tube 41. Constraint cylinders 42 are fixedly sleeved on both sides of the heat exchange tube 41, and the constraint cylinders 42 are fitted against the inner side of the first tube 11. A scraper rod 43 is fixedly connected between the sides of the constraint cylinders 42. A reinforcing plate 44 is fixedly installed inside the constraint cylinders 42 and is movably sleeved on the side of the mating rod 24. The reinforcing plate 44 is located on the upper side of the heat exchange tube 41 and is an annular plate with rectangular grooves evenly spaced on its sides. It is fixed to the side of the mating rod 24. A second mating block 45 is fitted and snaps against the lower side of the second rotating plate 32. Specifically, when the electric push rod 23 pushes the mating rod 24 upward, the second mating block 45 snaps against the lower side of the second rotating plate 32, and the first mating block 37 disengages from the side of the rotating frame 36. At this time, the rotation of the electric push rod 23 and the mating rod 24 can drive the second rotating plate 32, the first rotating plate 31, and the heat pipe 33 to rotate as a whole. In this way, the condensate entering through the heat pipe 33 can exchange heat with the coolant discharged through the water inlet pipe 411, and then through the connecting pipe. 412 The coolant is drained into the heat exchange tube 41. The condensate is further cooled by heat exchange through the heat exchange tube 41. The coolant can then be drained through the drain pipe 413 for subsequent use. In addition, the electric push rod 23 pulls the mating rod 24 so that the second mating block 45 is disengaged from the lower side of the second rotating plate 32 and snapped onto the upper side of the reinforcing plate 44. The first mating block 37 snaps onto the side of the rotating frame 36. At this time, the rotating frame 36 can clean the impurities on the side of the filter block 35. The reinforcing plate 44 drives the constraint cylinder 42 and the scraper 43 to rotate inside the first tube 11 for cleaning.

[0043] Mounting brackets 46 are provided at both ends of the heat exchange tube 41, and the mounting brackets 46 are fixedly installed inside the corresponding first tube barrel 11. The mounting bracket 46 is a snowflake-shaped circular block. A trigger rod 47 is slidably installed at the center position of the mounting bracket 46, and a part of the trigger rod 47 extends into the heat exchange tube 41. The trigger rod 47 is a cylindrical rod with a cross-section in the shape of a Chinese character "tu" and its side surface is a conical surface. A return spring 48 is fixedly connected between the side surfaces of the trigger rod 47 and the mounting bracket 46, and the return spring 48 is movably sleeved on the side surface of the trigger rod 47. Specifically, when the constraint cylinder 42 is rotated as a whole, the positions of the heat exchange tube 41 and the mounting bracket 46 are staggered. At this time, the constraint cylinder 42 can squeeze the trigger rod 47, and the trigger rod 47 pulls the return spring 48 to deform, making it fit against the side surface of the mounting bracket 46. The trigger rod 47 blocks the mounting bracket 46, so that the coolant can be physically blocked during cleaning to prevent the coolant from leaking into the first tube barrel 11.

[0044] As Figure 4 , Figure 6 and Figures 13 to 15 shown, the auxiliary component 5 includes a fixing plate 51. The fixing plate 51 is fixedly arranged inside the junction of the reaction kettle 1 and the first tube barrel 11, and the fixing plate 51 is movably sleeved on the side surface of the matching rod 24. The fixing plate 51 is a circular ring plate. An inner cavity 52 is formed inside the fixing plate 51. The inner cavity 52 is a circular ring cavity with a cross-section in the shape of an "L". First slots 521 penetrating the fixing plate 51 are equidistantly arranged on the inner wall of the inner cavity 52. The first slots 521 are rectangular slots. A movable plate 53 is movably installed inside the inner cavity 52, and the movable plate 53 is movably sleeved on the side surface of the matching rod 24. The movable plate 53 is a circular ring plate. Second slots 531 penetrating it are equidistantly arranged on the side surface of the movable plate 53. The second slots 531 are rectangular slots. A third matching block 54 is clamped and fitted to the lower side of the movable plate 53, and the third matching block 54 is fixedly sleeved on the side surface of the matching rod 24. Specifically, when the matching rod 24 is pushed upward by the electric push rod 23 and the second matching block 45 is clamped and fitted to the lower side of the second rotating plate 32, at this time the third matching block 54 is clamped and fitted to the lower side of the movable plate 53. At this time, the rotation of the matching rod 24 can drive the movable plate 53 to rotate synchronously inside the inner cavity 52. When the second slots 531 correspond to the first slots 521, the first tube barrel 11 and the reaction kettle 1 can be connected. When the second slots 531 and the first slots 521 are staggered, the first tube barrel 11 and the reaction kettle 1 can be blocked.

[0045] A mating plate 55 is fixedly installed at equal intervals on the upper side of the connecting rod 22. The mating plate 55 is a rectangular rod. A connecting plate 56 is fixedly installed between the sides of the mating plate 55. The connecting plate 56 is an arc-shaped plate. A mating cavity 551 is opened on the side of the mating plate 55. The mating cavity 551 is a rectangular cavity with a convex cross-section. An opening 552 penetrating the mating plate 55 is opened at equal intervals on the bottom wall of the mating cavity 551. The opening 552 is a circular hole. A conveying pipe 57 is fixedly installed through the side of the reactor 1 and corresponds to the position of the mating cavity 551. The conveying pipe 57 is connected to the treatment solution supply point and can supply and transport flocculant and rust remover. Specifically, the rust remover and flocculant are transported through the conveying pipe 57, and the treatment solution can enter the interior of the mating cavity 551 and be discharged from the opening 552. When the connecting rod 22 drives the mating plate 55 to rotate, the treatment solution and condensate are stirred and mixed.

[0046] Working principle:

[0047] When the condensate enters the second tube 12 area: First step, preliminary filtration. The condensate enters the second tube 12 from the third tube 13. After being cut and broken by the cutting plate 363, the condensate is then filtered for impurities by the filter block 35.

[0048] In the second step, preliminary heat exchange occurs. When condensate is supplied, the electric push rod 23 pushes the mating rod 24 upward, the second mating block 45 engages with the lower side of the second rotating plate 32, and the first mating block 37 disengages from the side of the rotating frame 36. The motor 21 drives the connecting rod 22 to rotate, which in turn drives the second rotating plate 32, the first rotating plate 31, and the heat-conducting pipe 33 to rotate as a whole. At the same time, the water inlet pipe 411 delivers coolant, and the coolant contacts the heat-conducting pipe 33 and the heat-conducting block 34 to initially remove the heat from the condensate.

[0049] The third step is to clean and unclog the impurities. The electric push rod 23 pulls the mating rod 24 downward, so that the first mating block 37 is engaged and attached to the side of the rotating frame 36, and the second mating block 45 is disengaged from the lower side of the second rotating plate 32. The mating rod 24 rotates, causing the rotating frame 36 to rotate as well. The rotating frame 36 can then scrape and remove the impurities on the side of the filter block 35. Subsequently, when the guide groove 362 corresponds to the mating groove 38, the impurities are discharged under the flushing water flow and collected by the external device.

[0050] When the condensate enters the area of ​​the first tube 11, the first step is secondary heat exchange. After heat exchange through the heat pipe 33, the condensate flows into the interior of the first tube 11. At the same time, the coolant inside the second tube 12 is discharged into the heat exchange tube 41 through the connecting pipe 412. At this time, the coolant and condensate can perform secondary heat exchange, so that the coolant can completely absorb the heat of the condensate.

[0051] The second step is internal cleaning. When the electric push rod 23 pulls the mating rod 24 downward, the rotating frame 36 scrapes off the impurities on the side of the filter block 35. At the same time, the second mating block 45 is snapped and attached to the upper side of the reinforcing plate 44. The mating rod 24 can drive the reinforcing plate 44 to rotate, and the constraint cylinder 42 and the heat exchange tube 41 can rotate as a whole. The scraper 43 rotates accordingly to clean the inside of the first tube 11.

[0052] The third step is physical flow interruption. When the heat exchange tube 41 and the constraint tube 42 rotate, the constraint tube 42 can be squeezed against the side of the trigger rod 47. The trigger rod 47 can pull the return spring 48 to deform. The trigger rod 47 fits against the side of the mounting bracket 46 to block it. This can effectively ensure the cut-off of the connecting pipe 412 and the drain pipe 413 and avoid the mixing and contamination of coolant and condensate during cleaning.

[0053] When the condensate enters the reactor 1 area, the first step is to add the treatment solution. After the condensate has been heated, it flows into the reactor 1. At this time, the feed pipe 57 transports the treatment solution into the mating cavity 551. Then it is discharged from the opening 552 and comes into contact with the condensate. At the same time, the connecting rod 22 drives the mating plate 55 and the connecting plate 56 to rotate and stir, so that the treatment solution and condensate are effectively mixed, ensuring the effect of rust removal and flocculation sedimentation.

[0054] The second step is settling. Before the electric push rod 23 pulls the mating rod 24 downward to clean the components, the third mating block 54 is snapped onto the lower side of the movable plate 53. The mating rod 24 drives the movable plate 53 to rotate. When the second slot 531 and the first slot 521 are staggered, the movable plate 53 seals the space between the reactor 1 and the first tube 11. At this time, the electric push rod 23 can pull the mating rod 24 downward. The rotation of the mating rod 24 drives the rotating frame 36 and the scraper 43 to perform the cleaning operation. At this time, the water flow inside the reactor 1 is cut off. The motor 21 slowly drives the connecting rod 22 to rotate. The stirring rod 221 slowly stirs the condensate inside the reactor 1, waiting for the condensate to flocculate and settle.

[0055] The third step is to open the drain pipe 14 to discharge the flocculent material accumulated at the bottom of the reactor 1 after the condensate has settled. Then, open the drain pipe 15 to discharge the treated condensate. This process can purify the condensate.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
